Cosa Commences Partner Funded Ambient Noise Tomography Survey at the Astro Uranium Project, Athabasca Basin, SaskatchewanJune 26, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - June 26, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to announce the commencement of an ambient noise tomography ("ANT") survey at the Astro project ("Astro" or the "Project"). Astro is located in the eastern Athabasca Basin, approximately 28 kilometres west of Cameco's McArthur River uranium Mine. The survey and supporting work are fully funded by Cosa's partner, Global Uranium Corporation (CSE: GURN) (OTCQB: GURFF) (FSE: Q3J) ("Global") per the option agreement (the "Agreement") announced by the Company on April 9th, 2025. Global has the right to earn up to an 80% interest in the Astro project by sole-funding $9.5 million in exploration expenditures and completing cash and share payments.HighlightsANT survey and supporting work are 100% funded by GlobalSurvey will identify seismic anomalies potentially attributable to prospective geological features including unconformity offsets and zones of strong hydrothermal alterationResults of the survey to guide proposed follow-up ground EM surveying and diamond drilling Andy Carmichael, VP Exploration of Cosa, commented: "Building on the success of the 2025 airborne program which defined over 25 kilometres of prospective conductive strike, a significant partner-funded ANT program at Astro has potential to generate compelling drill targets in an area that is entirely untested for the presence of a tier-1 eastern Athabasca uranium deposit. We look forward to the results of the ANT survey and ultimately advancing the Project towards a potential inaugural drill program in 2027."ANT SurveySurveying will be completed by CAUR Technologies ("CAUR") of Quebec, Canada. CAUR's objective is to deliver high-resolution shear wave velocity models that will refine geological interpretations and guide drill targeting by delineating lithological contrasts, structural features, and alteration zones within the lower Athabasca sandstone and upper basement rocks. The area of interest for the survey is the AS-1 target area (Figure 2), which covers a significant portion of a 25-kilometre-long east-northeast trending conductive corridor defined by a Project wide airborne survey completed by Cosa in 2025. East-northeast trending conductive corridors are high priority exploration targets in the Athabasca Basin as they are known to host tier-1 deposits like McArthur River and Cigar Lake. The survey design will deploy 300 seismic sensors and is expected to take two months to complete. Next StepsResults of the survey will be used to identify and prioritize prospective strike for additional work. Follow up partner-funded work may include ground-EM surveying in Q1 2027 to define conductive drill targets with an inaugural drill program to follow. About AstroThe Astro Project is located roughly 28 kilometres west of Cameco's McArthur River Mine, the world's largest high-grade uranium mine, and approximately 10 kilometres west of CanAlaska Uranium Ltd.'s Pike Zone which boasts world-class intersections (Figure 2). Only one historical drill hole, EK-01, has been completed on the Project. EK-01 failed to explain the strong conductive response it was targeting, suggesting the hole was not ideally located. Historical drill log notes favourable features in the sandstone including a brecciated and silicified interval in the upper portion, decametre-scale intervals of illite-dominated clay mineralogy throughout, and moderately bleached and slightly friable intervals in the lower 150 metres. All features are commonly associated with unconformity related uranium deposits of the Athabasca Basin. Roughly 11 kilometres to the southwest of EK-01 and within 700 metres of the Astro Project, strongly anomalous uranium geochemistry and pervasive hydrothermal alteration was intersected in the lower to medial sandstone of historical drill holes CR-06 and CR-15. Drilling completed by Cosa in 2024 failed to explain the source of the geochemical anomaly however ground-based EM work completed by Cosa indicates that the targeted conductor likely trends onto the Astro Project. Notably, the Project is unexplored for the extension of regional structures related to both the McArthur River and Fox Lake uranium deposits located roughly 28 and 17 kilometres east of Astro, respectively. Cosa and Global Uranium will execute a work plan designed to rapidly and efficiently canvas much of the Astro Project for identification of the most compelling drill targets. The depth to the unconformity at Astro is estimated to be between 850 and 975 metres.Figure 1 - Cosa's Eastern Athabasca Uranium ProjectsTo view an enhanced version of this graphic, please visit:

Cosa Announces Summer Drill Plans for the Darby Joint Venture with Denison MinesJune 15, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - June 15, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to announce summer plans for the Company's Darby ("Darby") project. Darby is a joint venture (the "Joint Venture") between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN) ("Denison") and is located 10 kilometres west of Cameco's Cigar Lake Mine in the eastern Athabasca Basin, Saskatchewan (Figure 1). Cosa is the operator of Darby and holds a 70% interest with Denison holding a 30% interest. Drilling at Darby is expected after completion of a significant drill program at the Company's Murphy Lake North joint venture to follow up uranium mineralization intersected in winter 2026.HighlightsDrilling planned at the Gamma trend to follow up structure, alteration, and strongly anomalous uranium geochemistry intersected during the winter 2026 drill programDrilling planned at the Bravo trend to follow up weak uranium mineralization proximal to structure and alteration intersected by historical drillingDrilling at Darby expected following completion of the significant drill program at the Company's Murphy Lake North joint ventureAndy Carmichael, Vice President of Exploration, commented: "Second only to the summer drilling planned to follow up the recent intersection of 5.0 metres averaging 0.55% U3O8 at our Murphy Lake North joint venture, targets at Darby are among our most compelling. Uranium mineralization has been intersected by several drill holes at Darby, reflecting the prospective geology of the area between the Cigar Lake and McArthur River uranium mines. Our planned summer drilling will continue to test areas where uranium mineralization and highly prospective structure and alteration are in proximity, with a focus this season on the Bravo and Gamma trends." Planned Darby DrillingDrilling at Darby is planned to comprise up to 2,000 metres at the Gamma and Bravo trends (Figure 2). Drilling at Gamma will follow up Cosa's winter 2026 drill program which intersected a broad zone of structure with significant unconformity offset, alteration, and elevated to strongly anomalous uranium geochemistry on trend with historical uranium mineralization (Figures 2, 3). Drilling at Bravo will follow up compelling historical results including structure, alteration, and uranium mineralization. Next StepsThe Company remains on schedule and expects to announce the commencement of drilling at the Murphy Lake North joint venture in the coming days. Drilling at Murphy Lake North is expected to take a minimum of two months to complete and will be followed by drilling at Darby.

https://images.newsfilecorp.com/files/9865/301449_6da72ecbd4cfdb1c_005full.jpgAbout DarbyLocated 10 kilometres west of the Cigar Lake Mine, Darby contains multiple prospective conductive trends and several intersections of weak uranium mineralization (Figures 1 and 2). Historical drilling indicates that many of these trends are highly prospective for uranium deposits characteristic of the eastern Athabasca Basin, yet most of the strike length has not been effectively evaluated. Work by Cosa in 2025 prioritized these trends and identified several historical drill holes with results that suggest proximity to uranium mineralization (See Cosa's news releases dated October 14, 2025 and January 21, 2026). Initial drilling results from winter 2026 significantly upgraded multiple trends.

Cosa Announces Largest Drill Program to Date at Murphy Lake North with Participation from Denison MinesMay 28, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - May 28, 2026) - Cosa Resources Corp. (TSX-V: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to announce summer plans for the largest drill program to date at the Company's Murphy Lake North ("MLN") project. Drilling is set to commence in mid-June and will follow up on uranium mineralization intersected in winter 2026. Muphy Lake North is a joint venture (the "Joint Venture") between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN) ("Denison") and is located three kilometres east of IsoEnergy's Hurricane deposit, in the eastern Athabasca Basin, Saskatchewan. Cosa is the project operator and holds a 70% interest with Denison holding a 30% interest.HighlightsMultiple intersections of unconformity related uranium mineralization remain open along strike for 600 metres in both directions; drilling to focus on step-out tests of the Cyclone mineralization approximately 265 metres below surfaceLargest drill program to date at Murphy Lake North will commence in mid-June and comprise approximately 6,000 metres, 15 drill holesDenison participating in funding 2026 exploration at MLN to maintain its 30% interest Keith Bodnarchuk, President and CEO, commented: "Having intersected 5.0 metres averaging 0.55% U3O8 within an extensive structure and alteration zone that remains open along strike, we are eager to return to site and commence what will be the largest drill program for Cosa and the Murphy Lake North Joint Venture since the inception of the Company. With Denison's support and participation in the funding of ongoing exploration, we are very excited to follow up the uranium mineralization at Murphy Lake North." Andy Carmichael, Vice President of Exploration, commented: "Exploration at Cyclone has progressed from initial drilling on the trend to preparing to follow up multiple intersections of uranium mineralization with significant untested strike in both directions in less than one year. We draw great encouragement from the similarity of Cyclone's sandstone alteration patterns to those at Hurricane, and from the significant nickel and cobalt coincident with uranium mineralization similar to Key Lake, Cigar Lake, and Hurricane." Planned Murphy Lake North DrillingSummer drilling at Murphy Lake North is expected to comprise approximately 15 drill holes totaling 6,000 metres focused on following up uranium mineralization intersected during winter 2026 which is open along strike for 600 metres in both directions. Drilling on section 3200E (Figure 2) will target major faults with alteration which remain untested at the unconformity, including the area south of mineralized drill hole MLN26-016 where mineralization is open for 40 metres to the south (Table 1, Figure 3). Drilling on 3200E will be followed by progressive step outs along strike. Additional compelling targets have been generated 600 metres to the east and 600 metres to the west by reinterpreting summer 2025 drilling results in the context of the winter 2026 results.Next StepsCrews are preparing to mobilize, and a rapid start-up is expected as the drill and supporting equipment remains on site at MLN. The Company expects to announce the commencement of drilling in mid-June, which will take approximately two months to complete, and will be followed by drilling at the Company's Darby joint venture.Table 1 - MLN Winter 2026 Assay ResultsHole

Hurricane is the world's highest-grade indicated uranium resource and was discovered and delineated for IsoEnergy Ltd. by current members of Cosa's team. The Larocque Lake trend also hosts the high-grade Larocque Lake Zone, Yelka Prospect, and Alligator Lake Zone. MLN contains the along-strike extension of basement geology underlying the Hurricane deposit (the Hurricane trend), as well as a parallel conductive trend to the south (the Cyclone trend). Cosa's winter 2026 drill program intersected several metres of basement hosted uranium mineralization within a broader zone of strong structure and alteration at the Cyclone trend.

Data and reports related to the 2020 ground EM survey completed by Denison are not presently available via SMAD and were supplied to Cosa by Denison.Verification of historical drilling results included confirming historical drill hole collar locations from air photos and ground checking selected collars with a handheld GPS unit. Basement and lower sandstone sections from most historical drill holes were relogged in 2024 and 2025 by Cosa. Verification of historical geophysical results included confirming the locations of geophysical survey grids from air photos, compiling survey data and interpretations, and evaluating whether interpreted geophysical results could be reasonably explained by historical and current drilling results. For MLN, Cosa engaged a consultant to re-interpret historical geophysical surveys to validate selected previous interpretations. Anomalous radioactivity in drill core was measured by removing 0.5 metre intervals of drill core to an area of background radioactivity and scanning it with an RS-125 hand held spectrometer to determine average CPS. Sampling was completed by collecting half-core splits measuring 0.5 metres in length with intervals that align with radioactive measurement intervals. Samples were transported to SRC Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan (ISO/IEC 17025:2005 accredited) for U3O8 assay and multielement analysis. Cosa inserts certified reference material (CRM) blanks and standards into the split core sample series as a QA/QC measure. SRC conducts a QA/QC programme which includes repeat analyses and insertion of CRM standards CAR218, BL4A, and BL2A. SRC's CRM results are verified by Cosa staff. U3O8 assay results are compared to RS-125 hand held scintillometer readings and down hole gamma probe results to verify chemical assays and measured radioactivity align.Qualified PersonThe Company's disclosure of technical or scientific information in this press release has been reviewed and approved by Andy Carmichael, P.Geo., Vice President, Exploration for Cosa.

Cosa Intersects up to 1.7% U3O8 Within Interval of 5.0 m of 0.55% U3O8 at Murphy Lake North Joint Venture with Denison MinesMay 26, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - May 26, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to report that chemical assays confirm previously-announced radioactive intersections include up to 1.7% U3O8 within a broader interval of 5.0 metres of 0.55% U3O8 at the Company's Murphy Lake North ("MLN") project. Muphy Lake North is a joint venture (the "Joint Venture") between Cosa and Denison Mines Corp. ("Denison") (TSX: DML) (NYSE American: DNN) and is located three kilometres east of IsoEnergy's Hurricane deposit, in the eastern Athabasca Basin, Saskatchewan. Cosa is the project operator and holds a 70% interest with Denison holding a 30% interest.HighlightsUranium mineralization confirmed in three holes featuring a best intercept in MLN26-013 of 5.0 metres averaging 0.55% U3O8 including 0.5 metres 1.7% U3O8 along the Cyclone trendThe 5.0 metre uranium intersection in MLN26-013 also contains 4.1% nickel and 1.7% cobalt, consistent with multiple polymetallic eastern Athabasca uranium deposits including Cigar Lake, Key Lake, and HurricaneUranium mineralization is shallow at 265 metres depth and remains open along strike for 600 metres to the west and 600 metres to the east Joint Venture is in final stages of planning its largest drill program to date to follow up these resultsKeith Bodnarchuk, President and CEO, commented: "This is a significant result for Cosa, with the assays confirming that Cyclone hosts uranium mineralization comparable to discovery intersections from multiple Athabasca uranium deposits. The Cyclone trend is an extensive corridor of strong structure and alteration that now features uranium mineralization that is open along strike for 600 metres in both directions. We expect to update the market in the coming days with plans for our largest drill program to date as a company. We appreciate the continued support and participation from our largest shareholder and Joint Venture partner Denison, and we have never been more excited to return to site and resume drilling."Andy Carmichael, Vice President of Exploration, commented: "Winter drilling showed that the Cyclone sandstone alteration patterns, basement lithologies, and faulting are strikingly similar to those at the nearby Hurricane deposit. Chemical assays indicate that Cyclone uranium mineralization contains significant quantities of nickel and cobalt, consistent with Hurricane and current- and past-producing mines like Key Lake and Cigar Lake. We are very encouraged that results have continued to improve as exploration advances and we are eager to continue follow up both on section and along strike." Murphy Lake North Geochemical AssaysChemical assays confirm uranium mineralization is the source of anomalous radioactivity intersected in three of five winter drill holes at the Murphy Lake North Joint Venture announced April 13, 2026 (Table 1, Figures 2 and 3). The strongest uranium mineralization is in MLN26-013, which intersected up to 1.7% U3O8 over 0.5 metres (310.5 - 311.0 metres) within a broader interval averaging 0.55% U3O8 over 5.0 metres (308.5 - 313.5 metres). Like sandstone hosted uranium deposits such as Hurricane, Key Lake, and Cigar Lake, the mineralization is polymetallic and includes significant quantities of nickel and cobalt.The 1.0 metre mineralized interval directly below the unconformity in MLN26-016 is immediately north of the strongest basement faulting intersected at Cyclone and 40 metres north of the nearest hole on section, suggesting a potential near-miss of the ideal target with significant space for additional mineralization (Figure 3).All mineralized intersections remain open along strike for at least 600 metres to the east and 600 metres to the west.

Inside America's Largest Conventional Measured and Indicated Uranium Deposit: Eagle Nuclear Energy Advances Aurora Toward Pre-FeasibilityMay 14, 2026 10:57 AM
PR Newswire (US) Issued on behalf of Eagle Nuclear Energy Corp.Environmental baseline studies commence at flagship Aurora Uranium Project ahead of 27,000-foot, 47-hole drill program scheduled to commence in July 2026; PFS targeted second half of 2027NEW YORK, May 14, 2026 /PRNewswire/ -- Equity Insider News Commentary — The United States burns through roughly 50 million pounds of uranium each year to fuel the world's largest fleet of nuclear reactors, and imports approximately 95% of that uranium from foreign suppliers.[1] That structural import dependence — combined with accelerating demand projections for nuclear power across AI data centers, grid expansion, and emerging space-deployment mandates — has placed domestic uranium development firmly into the national security conversation. Spot uranium pricing reached approximately $86.55 per pound as of May 1, 2026, up 24% over the trailing twelve months, providing the price backdrop against which the small group of U.S.-asset uranium developers has been advancing through the spring of 2026.[2] Eagle Nuclear Energy Corp. (NASDAQ: NUCL) — a next-generation nuclear energy company that owns the rights to the largest conventional, measured and indicated uranium deposit in the United States— on May 5, 2026 announced the commencement of environmental baseline studies in advance of the Company's previously announced 27,000-foot, 47-hole Pre-Feasibility Study ("PFS")-related drill program at its flagship Aurora Uranium Project, located along the Oregon–Nevada border.[3] The studies are being conducted by numerous engaged consultants ahead of the drill program, which is scheduled to commence in early July 2026 using two to three rigs over an estimated three- to four-month period.[3]Aurora: A Defined Conventional Uranium ResourceThe Aurora Uranium Project hosts 32.75 million pounds of indicated and 4.98 million pounds of inferred uranium resource under the SK-1300 TRS reporting standard.[2] The adjacent Cordex deposit, also held by the Company, is positioned as offering significant potential to expand the project's overall resource inventory beyond Aurora's current indicated and inferred base.[3] Together, the assets anchor Eagle's stated long-term strategy to develop an integrated nuclear energy platform that combines domestic uranium resources with exclusive Small Modular Reactor (SMR) technology —the integrated platform strategy the Company has emphasized since its February 25, 2026 Nasdaq listing..[2]Drill Program Engineering and Permitting SequenceOn April 1, 2026, Eagle announced its plans to conduct a 27,000-foot drill program at Aurora — designed by resource consultants BBA USA Inc. ("BBA") to address data gaps identified through a comprehensive Gap Analysis study and advance the project toward a PFS.[4] On April 9, 2026, the Company signed a Drilling Services Agreement with Fallon, Nevada-based Harris Exploration Drilling & Associates Inc. ("Harris Drilling"), which committed up to three track-mounted core drill rigs to complete the 47-hole program designed by BBA.[5]The permitting workstream advanced in parallel. On March 18, 2026, Eagle selected SLR International Corporation to lead the permitting effort at Aurora — a leading global mining and environmental consulting firm bringing experience with the federal and state permitting process for U.S. uranium developments.[6] On March 10, 2026, the Company announced it had joined the Uranium Producers of America — an industry trade association that aligns Eagle with the broader U.S. domestic uranium policy conversation.[6]The Company on April 15, 2026 provided its first quarter 2026 corporate update and financial results — the first quarter following the February 24, 2026 completion of its business combination with Spring Valley Acquisition Corp. II and the February 25, 2026 commencement of Nasdaq trading under the symbol "NUCL."[7]A Tightening Uranium Market BackdropThe price environment for U.S. domestic uranium developers has continued to firm through Q2 2026. Spot uranium pricing at approximately $86.55 per pound as of May 1, 2026 represents one of the strongest sustained price ranges of the past decade for the metal.[2] White House National Science and Technology Memorandum 3, issued April 14, 2026, mandates space-based nuclear deployment by 2028 and lunar reactor deployment by 2030 — federal directives that have increased the strategic importance of domestic uranium and the enriched fuel cycle running adjacent to it.[8]Across the broader uranium sector, producers operating U.S. and adjacent assets continue to reinforce the growing demand backdrop Eagle is advancing into. .Cameco Corporation (NYSE: CCJ) (TSX: CCO), one of the world's largest publicly listed uranium producers, has continued to advance the Cigar Lake operation and the McArthur River/Key Lake restart in the Athabasca Basin of Saskatchewan — alongside its strategic 49% interest in Westinghouse Electric Company. The Company has remained the benchmark name for senior uranium production exposure in the public markets.Uranium Energy Corp. (NYSE American: UEC) has continued to advance its U.S.-based in-situ recovery uranium production platform across Texas and Wyoming, alongside development-stage assets in the Powder River and Great Divide basins. UEC's positioning as one of the larger pure-play U.S. uranium developers makes its operational cadence a useful read on the broader U.S. uranium production conversation that Eagle's Aurora development pathway sits within.Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR), the U.S.'s largest producer of uranium concentrates and a leading rare earth elements producer, operates the White Mesa Mill in Utah — the only fully licensed and operating conventional uranium mill in the United States. Energy Fuels' integrated U.S. uranium-and-critical-minerals positioning has continued to draw attention as the broader domestic supply chain policy conversation has accelerated.Denison Mines Corp. (NYSE American: DNN) (TSX: DML) has continued to advance its Phoenix In-Situ Recovery uranium project at Wheeler River in Saskatchewan toward final investment decision, with the project positioned as one of the lower-cost potential new uranium operations in North America. Denison's progress in the Athabasca Basin provides one of the more closely watched development timelines in the senior uranium developer cohort.Bottom Line on NUCL's PositionThe May 5, 2026 commencement of environmental baseline studies marks the start of the PFS-related workstream proper at Aurora. With the drill program scheduled to commence in July 2026 under a signed Drilling Services Agreement with Harris Drilling, permitting led by SLR, resource modelling by BBA, and the Company holding what it describes as the largest conventional measured and indicated uranium deposit in the United States, Eagle has translated its February 2026 Nasdaq listing into an operational execution profile aligned with the broader uranium sector's current growth cycle. . The PFS is targeted for the second half of 2027; the next several quarters will be defined by drill progress, baseline-study completion, and the permitting interface across federal and state regulators.[3]Read more about Eagle Nuclear Energy Corp. at: usanewsgroup.com/nucl-profileCONTACT:Equity Insider

Denison Reports Financial and Operational Results for Q1 2026, Highlighted by Commencement of Site Preparation and Early Works for the Phoenix ISR Uranium Mine, and the Results of its Shareholder MeetingMay 12, 2026 8:16 PM
PR Newswire (Canada) TORONTO, May 12, 2026 /CNW/ - Denison Mines Corp. ("Denison" or the "Company") (TSX: DML) (NYSE American: DNN) today filed its Condensed Consolidated Financial Statements and Management's Discussion & Analysis ('MD&A') for the quarter ended March 31, 2026. Both documents will be available on the Company's website (at www.denisonmines.com), SEDAR+ (at www.sedarplus.ca) and EDGAR (at www.sec.gov/edgar). The highlights provided below are derived from these documents and should be read in conjunction with them. All amounts in this release are in Canadian dollars unless otherwise stated. View PDF VersionDavid Cates, President and CEO of Denison commented, "In February, the Phoenix In-Situ Recovery ("ISR") uranium mine ("Phoenix") became the first large-scale Canadian uranium mining project in over 20 years to receive all regulatory approvals required to commence construction. Shortly after achieving this landmark permitting accomplishment, the Company made its final investment decision ("FID") for Phoenix construction and, by the end of the first quarter, our Denison-Wood integrated project management team mobilized to the Wheeler River property and began executing schedule-critical site preparation and early works construction activities. In less than two months of on-site activity, our dedicated teams have completed (i) tree clearing activities across the primary mine site area, (ii) installation of construction management facilities, (iii) construction of our on-site helipad, (iv) civil works for the concrete batch plant pad, and (v) commencement of aggregate production at a nearby quarry. Civil activities continue to advance on site, including those necessary to establish the future airstrip. Taken together, we are on track to ramp up construction staffing and activities to complete early works and commence full-scale construction by the end of the second quarter, which aligns with our target to achieve first uranium production in mid-2028. We are, however, closely monitoring the widespread flooding that is impacting a portion of the road network in northern Saskatchewan. While our personnel are able to access the Phoenix site via helicopter, our ability to mobilize additional heavy equipment and certain supplies to site as planned may be impacted if the flooding persists and/or key infrastructure remains impacted. We recognize the significant efforts of the Province of Saskatchewan to rapidly respond to this unprecedented situation and are hopeful that conditions will improve in the coming days. At our 22.5%-owned McClean Lake operation, mining activities at the McClean North SABRE mine were minimal in the first quarter, with work focused on the completion of resource confirmation drilling in advance of the planned resumption of active mining later in the second quarter. Denison's unique combination of physical uranium holdings, active mine production from McClean Lake, and large-scale expected future mine production from the Phoenix and Gryphon deposits has resonated positively with some of the world's largest nuclear power utilities. This is reflected by our continued success in growing our uranium sales book – which now includes contracted sales commitments for nearly 8 million pounds of U3O8 plus advanced negotiations for a further 8 million pounds of U3O8. Notably, our customers include leading North American nuclear power utilities collectively responsible for over 50 reactors. In the first quarter, we entered near-term sales commitments with an average realized price over US$99/lb U3O8 for deliveries within a year. These sales are part of our Phoenix project financing efforts stemming from our physical uranium purchase from 2021, and demonstrate how our disciplined long-term strategy has facilitated significant participation in a rising uranium price environment. While the large majority of our commercial activity is focused on market-related pricing, we have also recently observed base-escalated pricing above levels reported in industry price publications, including prices on a present value basis in excess of US$100/lb U3O8 We believe this and other positive market signals continue to point to robust uranium market fundamentals, which align well with Denison's unique position as one of the few uranium suppliers globally that is on track to bring a sizeable new source of production to market before the end of the decade."HighlightsRegulatory Approval Received and Final Investment Decision Made to Construct the Phoenix Uranium Mine In February 2026, the Company announced receipt of approval from the Canadian Nuclear Safety Commission ("CNSC") for the Environmental Assessment ("EA") and the Licence to Prepare a Site & Construct (the "Construction Licence") for Phoenix. Phoenix is situated on the Wheeler River property ("Wheeler River") and is the first uranium mine in Canada to receive federal approval for construction in over 20 years. With the EA having previously been approved by the Province of Saskatchewan, and other provincial approvals necessary to commence construction already received, federal approval of the EA and the issuance of the Construction Licence represented the final regulatory approvals required to commence construction of Phoenix.Following the receipt of the CNSC approvals, Denison announced approval by its Board of Directors of the FID.Significant Advancement of Phoenix Site Preparation and Commencement of Early WorksFollowing the FID in late February 2026, the Integrated Project Management Team mobilized to the Phoenix site in early March and began overseeing the execution of site preparation activities and certain early works activities. By the end of April 2026, significant progress was made on schedule-critical activities including the completion of tree clearing activities across the primary mine site area prior to the onset of the migratory bird season. See Figure 1 for an annotated illustration of the site clearing activities completed to the end of April 2026. Site clearing and civil works were also completed for the concrete batch plant pad, which will allow for the mobilization of the batch plant to site in May 2026. Additionally, a rock crusher was mobilized to a nearby quarry, allowing for the commencement of aggregate production to support site civil activities.Civil activities at the main Phoenix site continue to advance, including the initiation of the construction of access roads and clearings necessary to establish the future site airstrip. Prior to the completion of the airstrip, scheduled for later in 2026, the majority of construction personnel will be transported to site via an 18-passenger helicopter. Regular air transport commenced in April 2026, following the completion of the site helipad.As Phoenix is a greenfield mine development project, significant site preparation activities and early works are required prior to the commencement of full-scale construction. Based on the early works completed to date, the ramp up of construction staff and activities to achieve a full-scale rate of construction is expected to occur before the end of the second quarter of 2026. Once construction activities ramp up, it is anticipated to take approximately two years to complete construction at Phoenix. This execution timeline positions Denison as one of the few uranium suppliers globally that is on track to provide a sizeable new source of uranium production before the end of the decade.Uranium Marketing Efforts Translate into Growing Customer Base and Supply ContractsThe proceeds from the sale of the Company's physical uranium holdings and inventory is an important part of the Company's project financing plans for Phoenix. In the first quarter of 2026, Denison agreed to sell 550,000 pounds of U3O8 with deliveries between the second quarter of 2026 and the first quarter of 2027 at an average price of US$99.07 per pound. At the end of the first quarter of 2026, 1,350,000 pounds of U3O8 were committed for deliveries between the second quarter of 2026 and the second quarter of 2027. The sales price has been fixed for the delivery of 950,000 pounds U3O8 for gross proceeds of US$87.5 million (average price of US$92.05 per pound U3O8). The remaining 400,000 pounds U3O8 of committed near-term sales are subject to market-related pricing, and approximately 500,000 pounds U3O8 in physical holdings and inventories remain uncommitted.Including near-term commitments, the Company has contracted firm uranium sales commitments for nearly 8 million pounds of U3O8 from its physical uranium holdings and expected future uranium production, and is in advanced negotiations for additional sales commitments of approximately 8 million pounds of U3O8, resulting in total contracted and advanced negotiation sales commitments of approximately 16 million pounds of U3O8. Customers include several leading North American nuclear power plant operators, collectively responsible for over 50 nuclear reactors, as well as multiple reputable industry intermediaries, which have each demonstrated significant interest in securing supply from Denison. Pricing mechanisms include a mix of market-related with no floors and ceilings, market-related with floors and ceilings, and base-escalated pricing. The large majority of commitments are on a market-related basis with deliveries contemplated to occur during the expected mine life of Phoenix.Construction Management Contract Awarded for PhoenixAlso in February 2026, Denison announced that, following a competitive tender process, it awarded Wood Canada Limited ("Wood"), a global leader in consulting and engineering, with the construction management contract (the "CM Contract") to oversee construction of the Phoenix mine. The CM Contract currently contemplates procurement and construction management scopes, whereby Wood will be responsible for (i) construction management of the full processing plant scope, (ii) installation of certain site infrastructure, and (iii) integrated project controls, ongoing procurement support, on-site safety oversight, as well as maintaining reporting and performance management standards. Such services will be provided by Wood in close consultation with Denison, with certain members of Wood's team and Denison's team holding complementary roles in an integrated project management team.Capital Cost Update for PhoenixIn January 2026, the Company reported that, based on the substantial completion of project engineering and execution of significant procurement activities since the effective date of the 2023 feasibility study for Phoenix (the "Phoenix FS"), an updated initial capital cost estimate for the Project has been released. Accounting for increases in inflation, cost increases, and project refinements, the Company estimated the total post- FID initial capital estimate for the Project to be approximately $600 million.2026 Annual Shareholders MeetingDenison is also pleased to report the passing of all items of business presented to shareholders at the Company's annual and special shareholders meeting held in Toronto today (the "Meeting"), as disclosed in the management information circular dated March 30, 2026.

Denison's common shares are listed on the Toronto Stock Exchange (the "TSX") under the symbol 'DML' and on the NYSE American exchange under the symbol 'DNN'.Denison is a uranium mining, exploration and development company with interests focused in the Athabasca Basin region of northern Saskatchewan, Canada. The Company has an effective 95% interest in its flagship Wheeler River Uranium Project, which is the largest undeveloped uranium project in the infrastructure rich eastern portion of the Athabasca Basin region of northern Saskatchewan. In mid-2023, the Phoenix FS was completed for the Phoenix ISR mining operation, and an update to the 2018 Pre-Feasibility Study ("2018 PFS") was completed for the Gryphon deposit as a conventional underground mining operation (the "Gryphon Update"). Based on the respective studies, both deposits have the potential to be competitive with the lowest cost uranium mining operations in the world. Permitting efforts for Phoenix commenced in 2019 and the required permits have been obtained to commence construction – including the July 2025 approval of the project's EA by the Province of Saskatchewan and the February 2026 federal approval of the EA and issuance of the Construction Licence. This milestone supported the FID and the subsequent commencement of early works activities at the Phoenix mine. Denison's interests in Saskatchewan also include a 22.5% ownership interest in the MLJV, which restarted mining with SABRE in 2025) and the McClean Lake uranium mill (currently utilizing a portion of its licensed capacity to process the ore from the Cigar Lake mine under a toll milling agreement), plus a 25.17% interest in the Midwest Main and Midwest A deposits held by the Midwest Joint Venture ("MWJV"), and a 70.55% interest in the Tthe Heldeth Túé ("THT") and Huskie deposits on the Waterbury Lake Property ("Waterbury"). The Midwest Main, Midwest A, THT and Huskie deposits are located within 20 kilometres of the McClean Lake mill. Taken together, the Company has direct ownership interests in properties covering ~457,000 hectares in the Athabasca Basin region.Additionally, through its 50% ownership of JCU (Canada) Exploration Company, Limited ("JCU"), Denison holds further interests in various uranium project joint ventures in Canada, including the Millennium project (JCU, 30.099%), the Kiggavik project (JCU, 33.8118%) and Christie Lake (JCU, 34.4508%).In 2024, Denison celebrated its 70th year in uranium mining, exploration, and development, which began in 1954 with Denison's first acquisition of mining claims in the Elliot Lake region of northern Ontario.Technical Disclosure and Qualified PersonThe technical information contained in this press release has been reviewed and approved by Chad Sorba, P.Geo., Denison's Vice President Technical Services & Project Evaluation, who is a Qualified Persons in accordance with the requirements of NI 43-101.CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTSCertain information contained in this press release constitutes 'forward-looking information', within the meaning of the applicable United States and Canadian legislation concerning the business, operations, and financial performance and condition of Denison.

Cosa Reports Anomalous Uranium in Sandstone at Darby Joint Venture with Denison MinesMay 6, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - May 6, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to report drilling results for the Company's Darby ("Darby") project. Darby is a joint venture (the "Joint Venture") between Cosa and Denison Mines Corp. ("Denison") (TSX: DML) (NYSE American: DNN) and is located 10 kilometres west of Cameco's Cigar Lake Mine in the eastern Athabasca Basin, Saskatchewan (Figure 1). Cosa is the operator of Darby and holds a 70% interest with Denison holding a 30% interest.HighlightsHighly anomalous uranium in sandstone and weak basement uranium mineralization (0.04% U3O8 over 0.5 metres) intersected at Charlie TrendProspective sandstone and basement faulting, alteration, and unconformity relief identified at Gamma TrendInitial drill program significantly upgraded three trends at DarbyAssays remain pending on exceptional winter 2026 Murphy Lake North drill program that intersected anomalous radioactivityKeith Bodnarchuk, President and CEO, commented: "Prior to intersecting radioactivity at Murphy Lake North, we completed an exciting drill program at our Darby Lake Joint Venture with Denison. We are very encouraged by the results from Cosa's initial drill program at Darby, which have further upgraded multiple trends. We are in the process of finalizing summer plans, which will be released in the coming weeks and are expected to comprise a significant drill program at Murphy Lake North with drilling at Darby to follow. With assays pending at Murphy Lake North, we expect to have important news flow ahead of the resumption of drilling in June."Andy Carmichael, Vice President of Exploration, commented: "Drilling at Gamma revealed the trend hosts a more than 100-metre-wide graphitic structural corridor with the strongest sandstone alteration known on the project and significant unconformity relief. With mineralization on trend to the north, Gamma is a high priority for further exploration. Drilling at Charlie intersected outstanding sandstone uranium content and weak basement hosted uranium mineralization, confirming the strong exploration potential of this trend. The exceptional winter 2026 drilling results from Murphy Lake North will remain our primary exploration focus, and these initial results from Darby are compelling additions to our inventory of excellent drill targets." Darby Winter DrillingThree holes were completed at Darby to test priority targets at the Charlie, Gamma, and Delta trends identified by Cosa's 2025 core relogging and reinterpretation program. Charlie Trend Winter drill hole DB26-39A followed up basement structure and anomalous1 sandstone uranium content in historical drill hole DB-09 and successfully intersected the targeted graphitic unit at the unconformity. DB26-39A intersected very strongly anomalous uranium content in the sandstone, averaging 5.6 ppm over 103.5 metres (600.0 - 703.5 metres) including a subinterval averaging 9.5 ppm over 53.5 metres (650.0 - 703.5 metres) in the basal sandstone (Figures 2 and 3). These values exceed the strongly anomalous results of DB-09 which intersected 2.0 ppm uranium over 116.8 metres (543.2 - 660 metres). DB26-39A also intersected 0.04% U3O8 over 0.5 metres (707.8 - 708.3 metres), which is the second intersection of weak uranium mineralization on trend. Several high priority follow up targets remain untested at Charlie.Gamma TrendWinter drilling results significantly upgraded the Gamma trend and generated several follow-up targets.The Gamma trend was prioritized for drilling based on elevated to anomalous sandstone uranium content proximal to graphitic basement faults in historical drill hole DB-17, and the presence of numerous intersections of uranium mineralization along trend north of Darby (Figures 2 and 4). DB26-41 targeted the DB-17 basement faults at the unconformity.DB26-41 intersected two decametre-scale intervals of faulting and alteration in the lower sandstone, elevated to anomalous sandstone uranium content, and identified 35 metres of unconformity relief relative to DB-17. Basement rocks are graphitic and non-graphitic metasediments overlying granite. Graphitic fault zones intersected 30 to 124 metres below the unconformity are generally thicker than those in DB-17 and some are enveloped by metre-scale zones of hydrothermal alteration.DB26-41 and DB-17 define a highly prospective geological environment which includes an approximately 150-metre-wide corridor of graphitic basement faulting, zones of hydrothermal alteration and faulting in the sandstone and basement, and uranium enrichment in the sandstone. The prominent unconformity relief is similar to unconformity offsets from reverse faulting present at several Athabasca uranium deposits, most notably at Cameco's McArthur River mine. Delta TrendDB26-42 followed up historical drill hole DB-27 (Figure 2), which intersected a 48-metre interval of continuously anomalous uranium content in the sandstone above graphitic basement faulting. DB26-42 targeted the DB-27 basement faulting at the unconformity and did not intersect any significant results; geochemical results remain pending. Several kilometres of prospective strike length remain at Delta.Next StepsAssays remain pending for DB26-42. Planning is underway for a summer drilling campaign at Darby which is expected to commence following completion of summer drilling at Murphy Lake North.1 - When analyzed using SRC's partial digestion and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method, Cosa considers uranium concentrations in the Athabasca sandstone greater than 0.5 ppm to be elevated, greater than 1.0 ppm to be anomalous, and greater than 4 ppm to be strongly anomalous.Figure 1 - Cosa's Eastern Athabasca Uranium Projects with Joint Venture ProjectsTo view an enhanced version of this graphic, please visit:

https://images.newsfilecorp.com/files/9865/296203_289f6d6b1437a904_006full.jpgAbout DarbyLocated 10 kilometres west of the Cigar Lake Mine, Darby contains multiple prospective conductive trends and several intersections of weak uranium mineralization (Figures 1 and 2). Historical drilling indicates that many of these trends are highly prospective for uranium deposits characteristic of the eastern Athabasca Basin, yet most of the strike length has not been effectively evaluated. Work by Cosa in 2025 prioritized these trends and identified several historical drill holes with results that suggest proximity to uranium mineralization (See Cosa's news releases dated October 24, 2025 and January 21, 2026). Initial drilling results from winter 2026 significantly upgraded multiple trends. Future drilling will include follow up of anomalous results from both winter 2026 and historical drilling. About Cosa Resources Corp.Cosa Resources is a Canadian uranium exploration company operating in northern Saskatchewan. The portfolio comprises roughly 237,000 ha across multiple underexplored 100% owned and Cosa-operated joint venture projects in the Athabasca Basin region, the majority of which reside within or adjacent to established uranium corridors.In January of 2025, the Company entered a transformative strategic collaboration with Denison Mines (TSX: DML) (NYSE American: DNN) that has secured access to several additional highly prospective eastern Athabasca uranium exploration projects. As Cosa's largest shareholder, Denison gains exposure to Cosa's potential for exploration success and its pipeline of uranium projects. The Company's primary focus through the remainder of 2026 will be drilling at the Murphy Lake North and Darby projects in the eastern Athabasca Basin. Drilling at Murphy Lake North will follow up the newly identified zones of anomalous radioactivity within an extensive zone of strong structure and hydrothermal alteration at the Cyclone trend. Drilling at Darby will follow up on intersections of anomalous geochemistry, structure, and zones of hydrothermal alteration from both winter 2026 drilling and historical drilling. Cosa's award-winning management team has a track record of success in Saskatchewan. In 2022, members of the Cosa team were awarded the AME Colin Spence Award for the discovery of the Hurricane uranium deposit. Cosa personnel led teams or had integral roles in the discovery of Denison's Gryphon deposit and held key roles in the founding of both NexGen and IsoEnergy.Technical DisclosureHistorical drilling and geophysical results for Darby and MLN were sourced from the Saskatchewan Mineral Assessment Database (SMAD).

The Uranium Shortage: 78 Gigawatts Under Construction and Not Enough FuelApril 29, 2026 9:05 AM
PR Newswire (Canada)

Issued on behalf of Eagle Nuclear Energy Corp.VANCOUVER, BC, April 29, 2026 /CNW/ -- USANewsGroup.com News Commentary — Seventy-eight gigawatts of nuclear reactor capacity are now under construction across 15 countries, according to the International Energy Agency's 2026 Global Energy Review, and global installed nuclear capacity sits at 420 GW[1]. That building spree just got louder: at the Paris Nuclear Energy Summit in March, 38 nations signed on to triple nuclear capacity by 2050, locking in sovereign fuel commitments that tighten the supply picture for years[2]. The capital now rotating into this sector is targeting companies already past the starting line, and five names sit at the front of that queue: Eagle Nuclear Energy Corp. (NASDAQ: NUCL), Cameco Corporation (NYSE: CCJ) (TSX: CCO), Uranium Energy (NYSE-A: UEC), NexGen Energy (NYSE: NXE) (TSX: NXE), and Denison Mines (NYSE-A: DNN) (TSX: DML).
The World Nuclear Association projects government targets could push global nuclear capacity to 1,446 GWe by 2050, well past the 1,200 GW tripling goal set at COP28[3]. With over 12 GW of new nuclear construction starts in 2025 alone, according to the IEA, the asymmetric upside now favors companies holding permitted sites, funded drill programs, and active construction timelines over early-stage explorers still years from first approvals[4].Eagle Nuclear Energy (NASDAQ: NUCL) just reported its first quarter as a publicly traded company, and the numbers tell a clean story: $31.3 million in cash, zero interest-bearing debt, and a flagship uranium project that is now moving toward drilling.The company's Aurora Uranium Project, located along the Oregon-Nevada border, holds 32.75 million pounds of indicated uranium and 4.98 million pounds of inferred uranium. That makes it the largest conventional, measured and indicated uranium deposit in the United States. Eagle Nuclear Energy completed its business combination with Spring Valley Acquisition Corp. II in February 2026 and began trading on the Nasdaq on February 25 under the ticker NUCL.Since listing, Eagle Nuclear Energy has moved quickly. The company announced a 27,000 ft drill program at Aurora in early April, designed to advance the project toward a Pre-Feasibility Study. The program consists of 47 diamond drill holes planned by resource consultants BBA USA Inc., with objectives spanning resource expansion, classification enhancement, advanced metallurgy, rock mechanics, and hydrogeological analysis. Each hole was designed to serve multiple purposes simultaneously, keeping the overall program limited without sacrificing any of its goals.Days later, Eagle Nuclear Energy engaged Harris Exploration Drilling to provide up to three track-mounted core drill rigs for the campaign, which is scheduled to begin in July and expected to wrap within three to four months. The company's permitting manager, SLR International Corporation, has already filed permit applications with the Bureau of Land Management and the Oregon Department of Geology and Mineral Industries. Both agencies have acknowledged receipt, and Eagle Nuclear Energy anticipates approvals in time for the July start.The broader strategy here is vertical integration. Eagle Nuclear Energy is not just exploring uranium. The company is pairing domestic uranium resources with exclusive Small Modular Reactor technology to build what it calls an integrated nuclear energy platform. At a time when operating reactors in the United States source more than 95% of their fuel from foreign suppliers, a domestic project with a clear path to development carries real strategic weight. Eagle Nuclear Energy's membership in the Uranium Producers of America reinforces that positioning, and the Pre-Feasibility Study is slated for completion in the second half of 2027.With cash on hand, a drill program locked in, permits filed, and rigs secured, Eagle Nuclear Energy is approaching a summer that could meaningfully reshape how the market values Aurora. For a company that only began trading two months ago, the pace of execution stands out.Other industry developments and happenings in the market include:Cameco Corporation (NYSE: CCJ) (TSX: CCO) signed a long-term agreement to supply nearly 22 million pounds of uranium ore concentrate to India's Department of Atomic Energy over a nine-year period, with deliveries expected to run from 2027 through 2035. The contract carries an estimated total value of approximately $2.6 billion, based on a uranium spot price of US$86.95 per pound, and was celebrated in Delhi alongside Indian Prime Minister Narendra Modi, Canadian Prime Minister Mark Carney, and Saskatchewan Premier Scott Moe."Cameco is proud to be a strategic partner with India to help meet its civil nuclear fuel needs and support its trade relationship with Canada," said Tim Gitzel, CEO of Cameco Corporation. "India is embarking on an ambitious nuclear expansion to power its development plans and meet the future energy security needs of its people."India currently operates 24 reactors with plans to reach 100 GW of nuclear capacity by 2047, representing a significant long-term demand driver for uranium supply. The new agreement builds on a previous five-year contract Cameco Corporation held with India beginning in 2015, reinforcing the company's position as a trusted nuclear fuel supplier of choice for sovereign buyers globally.Uranium Energy (NYSE-A: UEC) announced production commencement at its Burke Hollow project in South Texas following approval from the Texas Commission on Environmental Quality, making Burke Hollow the world's newest in-situ recovery uranium mine and the first new U.S. ISR operation to start in over a decade. Combined with recent capacity expansion approvals at Christensen Ranch in Wyoming, Uranium Energy now operates two active ISR hub-and-spoke platforms and is the only U.S. uranium company with two producing ISR production systems."The startup of Burke Hollow is a significant achievement for UEC, advancing the project from a grassroots discovery in 2012 to production in 2026," said Amir Adnani, President and CEO of Uranium Energy. "With two ISR operations now producing, and our Ludeman ISR project planned for startup in 2027, we are building a scalable, multi-faceted platform supported by the largest uranium resource base in the United States."Burke Hollow is the largest ISR uranium discovery in the United States, with multi-phase development potential designed to scale production in line with market demand. Uranium Energy maintains a 100% unhedged production strategy, holds the largest uranium resource base in the U.S., and is targeting growth across its three-platform ISR network to meet strengthening market fundamentals.NexGen Energy (NYSE: NXE) (TSX: NXE) received final federal approval for the Rook I uranium project in Saskatchewan's Athabasca Basin, with the Canadian Nuclear Safety Commission issuing both an Environmental Assessment approval and a Licence to Prepare Site and Construct, the last regulatory hurdle required to begin full construction. When operational, Rook I will produce up to 30 million pounds of uranium annually, representing more than 20% of global uranium supply and more than 50% of western world supply."NexGen is the foundational and necessary key to fueling that growth," said Leigh Curyer, Founder and CEO of NexGen Energy. "Our team, our asset, and this moment are aligned in a way that comes along once in a generation. Together with our Nation partners and our many valued stakeholders, we are well prepared and ready to execute the construction phase of the Rook I Project with the same scope, schedule and cost precision that has defined NexGen since incorporation in 2011."NexGen Energy made its Final Investment Decision ahead of the approval, with official construction commencing in summer 2026 and expected to take four years. All procurement, engineering, vendors, and capital are in place, with the company having worked in lockstep with Indigenous communities throughout the multi-year approval process.Denison Mines (NYSE-A: DNN) (TSX: DML) filed its audited 2025 annual results alongside a Final Investment Decision to construct the Phoenix in-situ recovery uranium mine at the Wheeler River property in Saskatchewan's Athabasca Basin, with site preparation and construction commencing in March 2026 and first production targeted by mid-2028. Denison Mines secured US$345 million through a senior convertible notes offering, appointed Wood Plc as construction manager, and advanced engineering to nearly 90% completion."Over the past twelve months, Denison continued to make significant investments in its assets, including its flagship Phoenix project," said David Cates, President and CEO of Denison Mines. "With receipt of all regulatory approvals necessary to start construction, significant advancement of construction planning and procurement efforts, appointment of Wood Plc as construction manager, and a strong balance sheet, we are ready to commence site preparation for and construction of the Phoenix ISR uranium mine later this month."McClean North, operated by joint venture partner Orano Canada, deployed the patented SABRE mining method and produced nearly 650,000 pounds U3O8 in 2025, one of the most productive new uranium mines in North America. Denison Mines also advanced delineation drilling at the Gryphon deposit and expanded its exploration JV portfolio with Skyharbour Resources.CONTACT:

Cosa Reports Anomalous Radioactivity in Multiple Drill Holes at the Murphy Lake North Joint Venture with Denison MinesApril 13, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - April 13, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to report the intersection of anomalous radioactivity in multiple drill holes and completion of the winter 2026 drilling program at the Company's Murphy Lake North Project ("MLN" or the "Project"). MLN is a joint venture (the "Joint Venture") between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN) ("Denison") and is located 3 kilometres east of IsoEnergy's Hurricane deposit in the eastern Athabasca Basin, Saskatchewan (Figure 1). Cosa is the operator and holds a 70% interest with Denison holding a 30% interest.HighlightsRadioactivity intersected in three drill holes Radioactivity remains open in multiple directions including for at least 600 metres along strike to the east and 600 metres to the west within the larger kilometre-scale Cyclone alteration zoneDepth of the radioactivity is shallow at approximately 260 metres vertically from surfaceCyclone trend structural corridor is over 100 metres wide and hosts significant alteration consistent with major eastern Athabasca uranium depositsKeith Bodnarchuk, President and CEO, commented: "Intersecting radioactivity in multiple drill holes is a tremendous result for Cosa, emphasizing the potential size and scale of this mineralizing system. The radioactivity alone is significant, but when factoring in the open space, depth, strong alteration and structure, this suggests we may be on the cusp of even more exciting results. With strong support from Denison Mines, assays pending, a healthy treasury, and numerous follow up targets, 2026 is shaping up to be a transformational year for Cosa." Andy Carmichael, Vice President of Exploration, commented: "Intersecting 5 metres of continuously anomalous radioactivity in the second round of drilling at Cyclone significantly upgrades the trend. Though warming conditions curtailed follow up, the additional holes resulted in additional radioactive intercepts separate from that of MLN26-013 and a deeper understanding of the trend's geology which will be invaluable during future drilling. With 600 metres of open strike length in either direction along a mineralized structural corridor, we're eager to resume drilling in summer 2026."MLN Winter Drilling ApproachWinter drilling at MLN followed up structure and alteration intersected at the Cyclone trend in summer 2025 (Figure 2). Five drill holes totaling 2,015 metres were completed during the program with three drill holes intersecting anomalous radioactivity1. The first drill hole of the program, MLN26-013, intersected the strongest radioactivity including a 5.0 metre interval of continuously anomalous radioactivity in the upper basement (see Cosa's news release dated March 24, 2026). Two holes were completed to directly follow up radioactivity in MLN26-013. Two additional holes were completed to define underlying geology ahead of summer drilling and follow up another radioactive intersection. All drill holes were completed on Section 3200E.MLN Winter Drilling Results Three of five drill holes intersected anomalous radioactivity (Table 1) in two discrete zones. Drilling also defined highly prospective geology with similarities to the Hurricane deposit and other unconformity related uranium deposits of the eastern Athabasca Basin (Figure 3).

All radioactive intersections are associated with faulting and broad zones of strong hydrothermal alteration in the sandstone and basement. All radioactive intersections remain open along strike to the east and west for at least 600 metres and some intersections remain open on section.MLN26-013, the first hole of the winter program, intersected a significant zone of structure and alteration underlain by faulted graphitic gneiss hosting several intervals of anomalous radioactivity between 306.5 and 313.5 metres ranging from 400 to 13,900 cps.Radioactivity in MLN26-013 was followed up to the north (MLN26-014) and south (MLN26-015). MLN26-014 intersected anomalous radioactivity in the upper basement within a 0.5 metre strongly altered interval. Elevated radioactivity was intersected in the lower sandstone by MLN26-015. 50 metres north of MLN26-013, MLN26-016 intersected a 1.0 metre interval of anomalous radioactivity immediately below the unconformity associated with a broad zone of strong alteration and structure. Cyclone 3200E GeologyDrilling determined the Cyclone trend is underlain by a package of graphitic and non-graphitic pelitic gneisses and quartzite over 100 metres in width. The full width of the mineralized structural corridor is unknown as additional prospective graphitic rocks may lie north and south of current drilling. Graphitic basement units host faulting and alteration. Basement faulting is best developed in the northernmost graphitic unit where MLN26-016 and -017 intersected metre- to decametre-scale fault zones, including a 35 metre interval that is enveloped by moderate to strong alteration (Figure 6). At the unconformity, the northern edge of this fault zone hosts radioactivity (MLN26-016) which remains open in several directions. 100 metres to the south, MLN26-013 and -014 intersected another graphitic fault zone which is enveloped by alteration and remains untested at the unconformity. Significant zones of sandstone structure and alteration are present throughout, and sandstone alteration patterns are similar to the Hurricane deposit where widespread bleached zones and distal silicified zones envelop broad desilicified zones cored by clay alteration (Figure 3). MLN26-013, -014, and -016 all intersected decametre-scale zones of sandstone faulting and alteration overlying the northern graphitic fault zone (Figure 3). Zones of faulting and alteration in the upper to middle sandstones of MLN26-013 and -016 suggest additional potential north of existing drilling. Multiple altered basement fault zones remain untested at the unconformity and down-dip.Next StepsThe Company and its Joint Venture partner, Denison Mines, will be finalizing summer plans in the coming weeks. The drill remains on site for rapid startup when drilling resumes this summer. Assays for all winter drill holes remain outstanding. About Murphy Lake North MLN covers a portion of the Larocque Lake trend and is located 2.7 kilometres east of the Hurricane deposit (Figures 1 and 2). Hurricane is the world's highest-grade indicated uranium resource and was discovered and delineated for IsoEnergy Ltd. by current members of Cosa's team. The Larocque Lake trend also hosts the high-grade Larocque Lake Zone, Yelka Prospect, and Alligator Lake Zone. MLN contains the along-strike extension of basement geology underlying the Hurricane deposit (the Hurricane trend), as well as a parallel conductive trend to the south (the Cyclone trend). Cosa's winter 2026 drill program intersected several meters of basement hosted radioactivity within a broader zone of strong structure and alteration at the Cyclone trend. Following up these results is the primary objective for the remainder of 2026 at MLN.1 – Cosa considers radioactivity anomalous when it (i) exceeds 350 cps measured with a Radiation Solutions RS-125 hand held spectrometer, (ii) is accompanied by structure and/or hydrothermal alteration consistent with Athabasca unconformity related uranium deposits, and (iii) spectrometric assay by RS-125 indicates uranium is the dominant source.Figure 1 – Cosa's Eastern Athabasca Uranium Projects with Joint Venture ProjectsTo view an enhanced version of this graphic, please visit:

The portfolio comprises roughly 237,000 ha across multiple underexplored 100% owned and Cosa-operated joint venture projects in the Athabasca Basin region, the majority of which reside within or adjacent to established uranium corridors.In January of 2025, the Company entered a transformative strategic collaboration with Denison Mines (TSX: DML) (NYSE American: DNN) that has secured access to several additional highly prospective eastern Athabasca uranium exploration projects. As Cosa's largest shareholder, Denison gains exposure to Cosa's potential for exploration success and its pipeline of uranium projects. The Company's primary focus through the remainder of 2026 will be drilling at the MLN project. in the eastern Athabasca Basin. Drilling at MLN will follow up the zones of newly identified anomalous radioactivity within an extensive zone of intense structure and hydrothermal alteration at the Cyclone trend. Cosa's award-winning management team has a track record of success in Saskatchewan. In 2022, members of the Cosa team were awarded the AME Colin Spence Award for the discovery of the Hurricane uranium deposit. Cosa personnel led teams or had integral roles in the discovery of Denison's Gryphon deposit and held key roles in the founding of both NexGen and IsoEnergy.Technical DisclosureHistorical drilling and geophysical results for MLN were sourced from the Saskatchewan Mineral Assessment Database (SMAD). SMAD sources for MLN and adjacent projects include file numbers 64L05-0161, 64L05-0180, 74I-0060, 74I-0066, 74I-0067, 74I01-0114, 74I08-0056, 74I09-0053, 74I09-0057, 74I09-0061, 74I09-0064, 74I09-0066, 74I09-0071, 74I09-0077, 74I09-0079, 74I09-0087, 74I09-0088, 74I09-0090, 74I09-0091, 74I09-0092, 74I09-0098, MAW00510, MAW01939, MAW02327, MAW02599, and MAW02395. Data and reports related to the 2020 ground EM survey completed by Denison are not presently available via SMAD and were supplied to Cosa by Denison.Verification of historical drilling results included confirming historical drill hole collar locations from air photos and ground checking selected collars with a handheld GPS unit. Verification of historical geophysical results included confirming the locations of geophysical survey grids from air photos, compiling survey data and interpretations, and evaluating whether interpreted geophysical results could be reasonably explained by historical and current drilling results. Additionally, Cosa engaged a consultant to re-interpret historical geophysical surveys to validate selected previous interpretations. All drill core is scanned with an RS-125 hand held spectrometer to check for radioactivity. Intervals of anomalous radioactivity are removed in 0.5 metre core lengths to an area of background radioactivity and average radioactivity for the 0.5 metre interval is measured. Cosa drill holes are also surveyed using an Imdex EZ Gamma (NOVAx) down hole probe to provide a continuous log of radioactivity at 0.1 metre intervals. Down hole probe results are compared to RS-125 results to verify the depth and strength of radioactive intervals and to assess for radioactivity though sections of lost core.Qualified PersonThe Company's disclosure of technical or scientific information in this press release has been reviewed and approved by Andy Carmichael, P.Geo., Vice President, Exploration for Cosa.

Cosa Reports 5.0 metres of Anomalous Radioactivity up to 13,900 CPS Intersected at Murphy Lake North Joint Venture with Denison MinesMarch 24, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - March 24, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to report that the first winter 2026 drill hole at the Company's Murphy Lake North Project ("MLN" or the "Project") has intersected 5.0 metres of anomalous radioactivity. MLN is a joint venture (the "Joint Venture") between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN) ("Denison") and is located 3 kilometres east of IsoEnergy's Hurricane Deposit in the eastern Athabasca Basin, Saskatchewan (Figure 1). Cosa is the operator and holds a 70% interest with Denison holding a 30% interest.HighlightsMLN26-013 intersected 5.0 metres of anomalous radioactivity up to 13,900 CPS1 in the upper basement approximately 260 metres vertically from surfaceStrong, structurally controlled alteration in the sandstone and basement is open in all directionsMLN26-013 is the lone drill hole within a 1.2 kilometre section of the Cyclone trendDrilling is ongoing and will test the immediate area around the radioactivityKeith Bodnarchuk, President and CEO, commented: "This intersection is an exceptional result. The shallow depth, proximity to existing infrastructure, and our team's history with this area, elevates the significance of this result. With a healthy treasury and strong support from our largest shareholder and Joint Venture partner Denison Mines, we are well positioned to ambitiously drill test Murphy Lake North for the remainder of 2026."Andy Carmichael, Vice President of Exploration, commented: "We are very encouraged that our first drill hole of the winter program intersected a significant width of anomalous radioactivity while following up the alteration identified in 2025. The mineralization, structure, and alteration intersected by MLN26-013 are open in all directions and the nearest drilling is 600 metres away along strike to the east and west. We'd like to recognize the instrumental roles our technical team of Keane Baseden (Senior Geologist), Haley Kitt and Kelly Stasiuk (Exploration Geologists) played in achieving this excellent result. We plan to use the remainder of our winter program to follow up the results of MLN26-013."MLN Winter DrillingWinter drilling at MLN was planned to follow up summer 2025 results at the Cyclone trend where broad zones of structure and alteration were intersected over a 2 kilometre strike length (Figure 2). The program's objectives were to target a gap in drilling at Cyclone and evaluate a potential untested trend approximately 100 metres south of Cyclone. Both planned target areas are best accessed in winter due to the presence of lakes. MLN26-013 was the first drill hole of the program and targeted the main Cyclone trend within a 1,200-metre gap between existing drill fences. MLN26-013MLN26-013 intersected broad zones of moderately to strongly altered sandstone from 200 metres to the unconformity at 299.4 metres. The strongest structure was intersected from 221 to 242 metres and is pervasively bleached and desilicified. The basal 9 metres of sandstone contains metre-scale zones of moderate to strong argillization within broader pervasively bleached sections and hosts hydrothermal hematite in the basal 1 metre.The unconformity was intersected approximately 250 metres vertically from surface. The upper basement is strongly and pervasively argillized and variably limonitized, hematitized, and chloritized to 306 metres (Figure 3). Graphitic and sulphidic pelitic gneiss immediately below the strongly altered zone hosts several intervals of anomalous radioactivity1 between 306.5 and 313.5 metres ranging from 400 to 13,900 cps (Table 1). This broader zone includes a 5.0 metre interval of continuously anomalous radioactivity from 308.5 to 313.5 metres. Core recovery through the mineralized zone was 100%. Basement below the radioactive zone is a sequence of dominantly non-graphitic metasediments hosting graphitic faulting. The drill hole was terminated at 425 metres.Table 1 - Winter 2026 MLN Drilling Program ResultsHole

 Radioactivity is total gamma from drill core measured with an RS-125 hand-held spectrometerMeasurements of total gamma on drill core are an indication of uranium content, but may not correlate with chemical assaysNext StepsThe remaining two targets planned for the program have been deferred in favour of immediate follow up of MLN26-013 which is ongoing. Chemical assays from MLN26-013 are pending.About Murphy Lake North MLN covers a portion of the Larocque Lake trend and is located 2.7 kilometres east of the Hurricane deposit (Figures 1 and 2). Hurricane is the world's highest-grade indicated uranium resource and was discovered and delineated for IsoEnergy Ltd. by current members of Cosa's team. The Larocque Lake trend also hosts the high-grade Larocque Lake Zone, Yelka Prospect, and Alligator Lake Zone. MLN contains the along-strike extension of basement geology underlying the Hurricane deposit (the Hurricane trend), as well as a parallel conductive trend to the south (the Cyclone trend). Cosa's winter 2026 drill program intersected several meters of basement hosted radioactivity within a broader zone of strong structure and alteration at the Cyclone trend. Following up these results is the primary objective for the remainder of 2026 at MLN.1 - Cosa considers radioactivity anomalous when it (i) exceeds 350 cps measured with a Radiation Solutions RS-125 hand held spectrometer, (ii) is accompanied by structure and/or hydrothermal alteration consistent with Athabasca unconformity related uranium deposits, and (iii) spectrometric assay by RS-125 indicates a uranium to be the dominant source.Figure 1 - Cosa's Eastern Athabasca Uranium Projects with Joint Venture ProjectsTo view an enhanced version of this graphic, please visit:

https://images.newsfilecorp.com/files/9865/289682_a604561404c0fb07_005full.jpgAbout Cosa Resources Corp.Cosa Resources is a Canadian uranium exploration company operating in northern Saskatchewan. The portfolio comprises roughly 237,000 ha across multiple underexplored 100% owned and Cosa-operated joint venture projects in the Athabasca Basin region, the majority of which reside within or adjacent to established uranium corridors.In January of 2025, the Company entered a transformative strategic collaboration with Denison Mines (TSX: DML) (NYSE American: DNN) that has secured access to several additional highly prospective eastern Athabasca uranium exploration projects. As Cosa's largest shareholder, Denison gains exposure to Cosa's potential for exploration success and its pipeline of uranium projects. Cosa's award-winning management team has a track record of success in Saskatchewan. In 2022, members of the Cosa team were awarded the AME Colin Spence Award for the discovery of the Hurricane uranium deposit. Cosa personnel led teams or had integral roles in the discovery of Denison's Gryphon deposit and held key roles in the founding of both NexGen and IsoEnergy.The Company's focus throughout 2026 is drilling at the Darby and MLN projects in the eastern Athabasca Basin. Both projects are operated by Cosa and are 70/30 joint ventures between Cosa and Denison respectively. Drilling at Darby will evaluate target areas with anomalous uranium, clay alteration, and historical mineralization intersected nearby. Drilling at MLN will follow up a zone of newly identified anomalous radioactivity intersected by winter 2026 drill hole MLN26-013. Technical DisclosureHistorical drilling and geophysical results for MLN were sourced from the Saskatchewan Mineral Assessment Database (SMAD). SMAD sources for MLN and adjacent projects include file numbers 64L05-0161, 64L05-0180, 74I-0060, 74I-0066, 74I-0067, 74I01-0114, 74I08-0056, 74I09-0053, 74I09-0057, 74I09-0061, 74I09-0064, 74I09-0066, 74I09-0071, 74I09-0077, 74I09-0079, 74I09-0087, 74I09-0088, 74I09-0090, 74I09-0091, 74I09-0092, 74I09-0098, MAW00510, MAW01939, MAW02327, MAW02599, and MAW02395. Data and reports related to the 2020 ground EM survey completed by Denison are not presently available via SMAD and were supplied to Cosa by Denison.Verification of historical drilling results included confirming historical drill hole collar locations from air photos and ground checking selected collars with a handheld GPS unit. Verification of historical geophysical results included confirming the locations of geophysical survey grids from air photos, compiling survey data and interpretations, and evaluating whether interpreted geophysical results could be reasonably explained by historical and current drilling results. Additionally, Cosa engaged a consultant to re-interpret historical geophysical surveys to validate selected previous interpretations. All drill core is scanned with an RS-125 hand held spectrometer to check for radioactivity. Intervals of anomalous radioactivity are removed in 0.5 metre core lengths to an area of background radioactivity and average radioactivity for the 0.5 m interval is measured. Cosa drill holes are also surveyed using an Imdex EZ Gamma (NOVAx) down hole probe to provide a continuous log of radioactivity at 0.1 metre intervals. Down hole probe results are compared to RS-125 results to verify the depth and strength of radioactive intervals and to assess for radioactivity though sections of lost core.

Utah's Forgotten Uranium Belt Is Getting a Second Look. Here's Why the Timing Matters.March 23, 2026 2:14 PM
PR Newswire (Canada)

Issued on behalf of EagleOne Metals CorporationVANCOUVER, BC, March 23, 2026 /CNW/ -- Equity-Insider.com — Thirty-five miles south of Hanksville, Utah, in the heart of some of the highest-grade historical uranium country in the American West, there's a 206-acre property that was drilled once in 2008, returned mineralized intercepts across six commodities, and then sat untouched for nearly two decades.







It's not hard to understand why. Uranium spent most of the 2010s in the penalty box. Spot prices languished below $30 per pound. Nobody was acquiring uranium ground in Utah. Nobody was funding exploration for rare earths in the Colorado Plateau. The economics didn't work, and the geopolitical urgency didn't exist.Both of those conditions have reversed. Uranium is now approaching $92 per pound. The IEA projects a 30% copper supply shortfall by 2035. Rare earth supplies outside China cover less than 40% of projected demand. And the U.S. government has committed more than $30 billion to secure critical mineral supply chains in just the past six months, including a $12 billion Project Vault strategic stockpile and a $2.7 billion DOE enrichment expansion.The companies best positioned for this environment are the ones that already hold ground. Cameco (TSX: CCO) (NYSE: CCJ), the world's largest publicly traded uranium company, recently partnered with the U.S. Government and Brookfield to accelerate Westinghouse nuclear reactor deployments — backed by $80 billion in aggregate government investment. Cameco is extending its Cigar Lake mine to 2036 and ramping McArthur River toward 25 million pounds annually. The market is paying $1,416 per pound of Cameco's future uranium capacity.NexGen Energy (TSX: NXE) (NYSE: NXE) is building what it positions as the world's largest and lowest-cost uranium mine at Rook I in Saskatchewan's Athabasca Basin. With estimated production costs under $10 per pound and spot uranium near $92, the margin thesis is extraordinary. NexGen raised C$800 million for construction and expects its Canadian Nuclear Safety Commission hearings this year. Denison Mines (TSX: DML) (NYSE: DNN) announced a final investment decision in March 2026 to construct the Phoenix in-situ recovery uranium mine at Wheeler River — 56.7 million pounds of proven and probable reserves, a projected IRR exceeding 80%, and production targeted for 2028 using a method that costs 15–70% less than conventional mining.On the rare earth side, MP Materials (NYSE: MP) operates the only scaled rare earth mining and processing site in North America at Mountain Pass, California. As Beijing tightened export controls on seven strategic rare earth elements in early 2026, MP's position as the Western hemisphere's primary source of NdPr oxide became acutely strategic. The company is building downstream magnet manufacturing capacity to supply EV and defense customers directly.These are billion-dollar companies operating in the same commodity environment that just created an opportunity at the opposite end of the valuation spectrum.EagleOne Metals Corporation (CSE: EAGL) (FSE: IJ2) recently signed a binding Letter of Intent to acquire 100% of the Poison Springs Uranium/Rare Earths Project in Utah for US$50,000. The 206.6-acre property returned mineralized intercepts across uranium, copper, silver, cobalt, nickel, and rare earth elements neodymium, praseodymium, and europium from a single 2008 drill campaign. Both uranium and REEs appear on the U.S. Critical Minerals List. Historical drilling by Cotter Corporation in nearby Hatch Canyon during 1978–1979 confirmed widespread mineralization across the broader region. Follow-up targets sit at less than 100 metres depth. A Triassic Chinle formation target carries additional potential for copper, vanadium, zinc, nickel, cobalt, and REEs.The Utah play is one piece of a broader portfolio. EagleOne's 100%-owned Hébécourt Township property in Quebec's Abitibi Greenstone Belt — a jurisdiction that has produced over 200 million ounces of gold historically — returned two priority anomalies targeting gold and copper. The adjacent Magusi West project produced gold anomalies up to 0.156 ppm and copper anomalies up to 186 ppm across 618 soil samples. And through a non-binding LOI with Surupampa Metals, EagleOne has a path to a Peruvian copper-gold asset.Four properties. Three countries. Gold, silver, copper, uranium, and rare earth elements. A C$240,000 financing pending. Market capitalization: approximately C$5 million.The structural deficit across uranium, copper, and rare earths is no longer a forecast. It's the primary driver behind the largest government mineral investment in American history. EagleOne Metals (CSE: EAGL) is assembling multi-commodity critical minerals exposure at the exact moment the policy environment and the price environment are converging — and the market hasn't priced it in yet.For more information on EagleOne Metals Corporation (CSE: EAGL) (FSE: IJ2) and its critical minerals portfolio, visit Equity-Insider.comRead this and more on EagleOne at: Equity-Insider.comArticle Source: https://usanewsgroup.com/2026/03/12/exploring-the-minerals-powering-the-digital-and-energy-future/CONTACT:

Original: Utah's Forgotten Uranium Belt Is Getting a Second Look. Here's Why the Timing Matters.

Cosa Announces Expansions to Orion Project and Joint Ventures with Denison MinesMarch 3, 2026 8:00 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - March 3, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to announce expansions to the Murphy Lake North ("MLN"), Darby ("Darby"), and Orion ("Orion") projects (Figure 1). Darby and MLN are joint ventures (the "Joint Venture") between Cosa and Denison Mines Corp. ("Denison") (TSX: DML) (NYSE American: DNN) and are located 10 kilometres west of Cameco's Cigar Lake Mine and three kilometres east of IsoEnergy's Hurricane Deposit, respectively. Cosa is the operator of both and holds a 70% interest with Denison holding a 30% interest in each. Orion is 100% owned by Cosa and is located 5 kilometres northwest of Darby.HighlightsSix claims totalling 2,669 hectares added at Darby, MLN, and Orion to cover known conductive features, inferred extensions, and areas proximal to favourable drilling resultsAll claims acquired for minimal cash consideration with no encumbrancesJustin Rodko P. Geo, Vice President of Corporate Development, commented: "We are pleased to have expanded the Darby and Murphy Lake North Joint Ventures as well as our underexplored and prospective Orion project. All claims were acquired at low cost with no royalties and capture the interpreted extensions of known conductive and/or mineralized trends and expand the projects proximal to positive drilling results. We remain committed to advancing exploration and target generation across our eastern Athabasca portfolio as the Company is actively drilling the Darby JV, and winter drilling and ground-based resistivity surveying are planned to follow at MLN."DarbyTwo claims totalling 758 hectares were acquired and extend the northern border of Darby immediately south of the Tucker Lake Uranium Zone (Figures 1 and 2). The expanded area covers the strike extension of the Delta trend immediately northeast of the most recent electromagnetic (EM) survey completed at Darby. The 2011 survey defined the northeast-trending Delta conductor, which has not been drill tested and has been flagged by the JV for first pass drilling as early as H2-2026. Also in the expanded area, ZTEM survey results suggest potential for an extension of the Echo trend. The Darby claims were acquired from a third party for a cash payment with no encumbrances.Murphy Lake NorthThree claims totalling 345 hectares were acquired at Murphy Lake North to the south of the Cyclone trend where Cosa's 2025 drilling intersected broad zones of sandstone alteration and structure above graphitic basement rocks over a strike length of 2 kilometres (Figures 1 and 3). The claims were acquired by low-cost staking.OrionOne claim totalling 1,564 hectares was acquired at Orion. The claim extends Orion to the southeast and covers a zone of enhanced basement-hosted conductivity near the edge of the conductivity model generated from Z-Tipper Electromagnetic (ZTEM) surveying completed by Cosa in 2025. The zone of basement conductivity coincides with an historical conductor in a digital compilation by the Saskatchewan Government and is located within a magnetic high, suggesting a favourable structural setting. The Orion claim was acquired from a third party for a cash payment with no encumbrances.About DarbyLocated 10 kilometres west of the Cigar Lake Mine, Darby contains multiple prospective conductive trends and several historical intersections of weak uranium mineralization (Figures 1 and 2). Historical drilling demonstrates that many of these trends are highly prospective for uranium deposits characteristic of the eastern Athabasca Basin, yet most of the strike length has not been effectively evaluated. Work by Cosa in 2025 prioritized these trends and identified several historical drill holes with results that suggest proximity to uranium mineralization (See Cosa's news releases dated October 24, 2025 and January 20, 2026). Cosa is currently undertaking the first diamond drilling program at Darby since 2009.About Murphy Lake North MLN covers a portion of the Larocque Lake trend and is located 2.7 kilometres east of the Hurricane deposit (Figures 1 and 3). Hurricane is the world's highest-grade indicated uranium resource and was discovered and delineated for IsoEnergy Ltd. by current members of Cosa's team. The Larocque Lake trend also hosts the high-grade Larocque Lake Zone, Yelka Prospect, and Alligator Lake Zone. MLN contains the along-strike extension of basement geology underlying the Hurricane deposit (the Hurricane trend), as well as a parallel conductive trend to the south (the Cyclone trend). Drilling by Cosa in 2025 intersected zones of sandstone alteration and structure associated with graphitic basement structures along both trends. Following up these positive results is the primary 2026 objective at MLN.Cosa intends to commence drilling at MLN in Q1 2026 which will be followed by project-wide DC-Resistivity surveying ahead of an expanded summer drilling campaign. About OrionOrion is located 29 kilometres west of the Cigar Lake uranium mine and immediately east of Orano's Parker Lake Project. Orion covers approximately 25 kilometres of strike length of the interpreted extension of the Larocque Lake Trend and the interpreted intersection of the Larocque Lake and Cigar Lake-Tucker Lake trends. The fertile Larocque Lake Trend hosts numerous occurrences of high-grade mineralization to the northeast, including the Hurricane Deposit, while the portion covered by Orion is highly underexplored and has been tested by only two drill holes.Figure 1 - Cosa's Eastern Athabasca Uranium Projects with Joint Venture ProjectsTo view an enhanced version of this graphic, please visit:

https://images.newsfilecorp.com/files/9865/286087_bc8020ee5476b9d8_005full.jpgAbout Cosa Resources Corp.Cosa Resources is a Canadian uranium exploration company operating in northern Saskatchewan. The portfolio comprises roughly 237,000 ha across multiple underexplored 100% owned and Cosa-operated joint venture projects in the Athabasca Basin region, the majority of which reside within or adjacent to established uranium corridors.In January of 2025, the Company entered a transformative strategic collaboration with Denison Mines (TSX: DML) (NYSE American: DNN) that has secured access to several additional highly prospective eastern Athabasca uranium exploration projects. As Cosa's largest shareholder, Denison gains exposure to Cosa's potential for exploration success and its pipeline of uranium projects. Cosa's award-winning management team has a track record of success in Saskatchewan. In 2022, members of the Cosa team were awarded the AME Colin Spence Award for the discovery of the Hurricane uranium deposit. Cosa personnel led teams or had integral roles in the discovery of Denison's Gryphon deposit and held key roles in the founding of both NexGen and IsoEnergy.The Company's focus throughout 2026 is drilling at the Darby and MLN projects in the eastern Athabasca Basin. Both projects are operated by Cosa and are 70/30 joint ventures between Cosa and Denison respectively. Drilling at Darby will evaluate target areas with anomalous uranium1, clay alteration, and historical mineralization intersected nearby. Drilling at MLN will follow up 2025 drilling which intersected broad zones of structurally controlled alteration over roughly 2 kilometres of strike length. 1 - When analyzed using SRC's partial digestion and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method, Cosa considers uranium concentrations in the Athabasca sandstone greater than 0.5 ppm to be elevated, greater than 1.0 ppm to be anomalous, and greater than 4 ppm to be strongly anomalous.Technical DisclosureHistorical drilling and geophysical results for Darby and MLN were sourced from the Saskatchewan Mineral Assessment Database (SMAD). SMAD sources for Darby include file numbers 74H14-0021, 74H14-0023, 74H15-0041, 74H15-0053, 74H15-0055, 74H15-0056, 74H15-0066, 74H15-0067, 74I02-0031, 74I02-0042, 74I02-0053, 74I02-0080, 74I02-0095, and MAW00516.

Data and reports related to the 2020 ground EM survey completed by Denison are not presently available via SMAD and were supplied to Cosa by Denison.Verification of historical drilling results included confirming historical drill hole collar locations from air photos and ground checking selected collars with a handheld GPS unit. Basement and lower sandstone sections from most historical drill holes were relogged in 2024 and 2025 by Cosa. For Darby, verification of geochemical results for drill holes completed between 2008 and 2010 was facilitated by the reissuance of analytical certificates to Cosa by the Saskatchewan Research Council (SRC). Cosa thanks the SRC for its valued assistance in increasing confidence in the historical dataset. Verification of Orion drilling results includes relogging basement and lower sandstone from the two historical drill holes completed on the Project.Verification of historical geophysical results included confirming the locations of geophysical survey grids from air photos, compiling survey data and interpretations, and evaluating whether interpreted geophysical results could be reasonably explained by historical and current drilling results. For MLN, Cosa engaged a consultant to re-interpret historical geophysical surveys to validate selected previous interpretations.

Americas Mineral Infrastructure Draws Capital As Critical Materials Deficits DeepenFebruary 3, 2026 10:22 AM
PR Newswire (US)

Issued on behalf of Americore Resources Corp. VANCOUVER, BC, Feb. 3, 2026 /PRNewswire/ -- EquityInsider.com News Commentary — Across the Americas, leaders are urging action to meet the coming demand of all kinds of minerals and metals that are in increasingly higher demand. Treasury Secretary Bessent's January mobilization of 12 nations to secure critical mineral supply chains[1] was immediately reinforced by the Department of Energy's $134 million commitment to domestic rare earth production[2]. This structural realignment federalizes the de-risking of North American projects, creating a premium environment for Americore Resources Corp. (TSXV: AMCO) (OTCQB: AMCOF), USA Rare Earth (NASDAQ: USAR), Denison Mines (NYSE-A: DNN) (TSX: DML), Canada Nickel Company (TSXV: CNC) (OTCQB: CNIKF), and Bravo Mining (TSXV: BRVO) (OTCQX: BRVMF).







Fitch's BMI forecasts the global silver market deficit will persist throughout 2026 as industrial consumption eclipses mine supply for a fifth consecutive year[3]. With the International Energy Agency projecting 40-50% electricity demand growth by 2035[4], institutions are rotating capital toward the sovereign assets required to sustain this urgent infrastructure expansion.Americore Resources Corp. (TSXV: AMCO) (OTCQB: AMCOF) is advancing a strategic initiative at its Trinity Silver Project in Nevada that could unlock near-term cash flow in today's ~$100 silver market. The company announced it is evaluating options to monetize historic surface stockpiles that potentially contain approximately 400,000 ounces of silver in oxide material and 365,000 ounces in sulphide material, material that is already mined and sitting at surface without the typical delays associated with starting new mining operations.The timing matters because silver prices have surged past $100 per ounce, making previously marginal stockpiles economically interesting. Americore is reviewing two processing pathways: off-site toll processing that could enable rapid monetization with limited capital requirements, or construction of an on-site pilot plant offering greater control over recoveries and long-term scalability. The company plans reverse circulation drilling, backhoe trenching, and metallurgical testing to confirm grades and optimize processing methods, with results expected to guide processing decisions and economic evaluations."Evaluating the monetization of historic stockpiles is a highly strategic move," stated Jeff Poloni, CEO of Americore. "It provides potential near-term value, delivers critical metallurgical insights, and helps accelerate Trinity toward a PEA."The Trinity Project sits in Pershing County, Nevada, just 23 miles from Lovelock, in an area with established infrastructure and proven silver production history. Between 1987 and 1988, U.S. Borax mined over one million tons from the historic Trinity pit and produced approximately five million ounces of silver through heap-leach operations, proving the district can generate real metal.Americore has been aggressively expanding its land position over the past several months, which matters because controlling more prospective ground means more potential ounces. The company now controls approximately 22,700 acres through direct staking and a strategic option agreement with Primus Resources for claims that returned grab samples as high as 1,690 grams per tonne silver. This expansion means the company now controls all ground covered by a 2012 historic resource estimate that tripled the resource base to 36 million ounces of silver equivalent.The company recently completed a drone magnetometer survey covering 312 line kilometers to map structural trends, with results expected to support upcoming drill targeting. Near-term exploration plans include drilling 5 to 10 core holes twinning historic drillholes to verify data and provide fresh material for metallurgical testing, followed by step-out drilling toward a new mineral resource estimate targeted for Q2 2026.CONTINUED… Read this and more news for Americore Resources at:https://equity-insider.com/2026/01/12/the-only-silver-that-matters-now-is-silver-you-can-touch/ https://equity-insider.com/2025/04/14/with-funding-commitments-in-place-a-gold-mine-is-being-built-and-this-stock-is-still-under-0-20/In other industry developments and happenings in the market include:USA Rare Earth (NASDAQ: USAR) has announced entry into a non-binding Letter of Intent with the U.S. Department of Commerce covering $1.6 billion including $277 million in proposed federal funding and a $1.3 billion proposed senior secured loan under the CHIPS Act. The company has concurrently raised $1.5 billion in a private sector PIPE transaction anchored by Inflection Point, bringing total capital to $3.1 billion."This landmark collaboration with the U.S. Government represents a transformative step in USA Rare Earth's mission to secure and grow a resilient, independent domestic rare earth value chain," said Barbara Humpton, CEO of USA Rare Earth. "We are grateful to President Trump, Secretary Lutnick, and Secretary Wright for their support and recognition of the strategic importance of rare earth materials and permanent magnets."The capital will accelerate development of a mine-to-magnet platform that by 2030 will extract 40,000 metric tons per day of rare earth feedstock from the Round Top deposit beginning commercial production in 2028. USA Rare Earth will process 8,000 metric tons per annum of heavy rare earth elements and critical mineral oxides including dysprosium, terbium, yttrium, and hafnium.Denison Mines (NYSE-A: DNN) (TSX: DML) announced grid power availability at the future Phoenix in-situ recovery uranium mine site following completion of a new 138kV transmission line by SaskPower. The six-kilometer transmission line connects Phoenix to Saskatchewan's existing grid infrastructure and provides access to up to 8.8 MW of power under a five-year supply agreement."We thank SaskPower for the safe installation of the new high-voltage transmission line, on schedule and on budget," said David Cates, President and CEO of Denison Mines. "As power is a crucial component of planned site infrastructure for Project construction and future operation, the availability of grid power supply at the site represents a major Project milestone."The electrification milestone significantly de-risks Phoenix construction as grid power is on the critical path for establishing the freeze wall surrounding the initial mining area. Denison Mines has procured long-lead electrical distribution equipment including the main transformer, substation components, and switchgear, all scheduled for delivery and installation during the first construction year, subject to final regulatory approvals and investment decision.Canada Nickel Company (TSXV: CNC) (OTCQB: CNIKF) has awarded Ausenco Engineering Canada ULC a contract to commence detailed engineering for the Process Plant and supporting infrastructure at the Crawford Nickel Sulphide Project. The company targets commencing construction on Crawford by year-end following significant endorsements from the federal government with the referral to the Major Projects Office and last week's announcement naming Crawford to Ontario's One Project, One Process framework."After receiving significant endorsements from the federal government with the referral to the Major Projects Office, and last week's announcement naming Crawford to Ontario's One Project, One Process framework, we are very pleased to move to this next stage in Crawford's development with Ausenco, a global engineering and consulting leader," said Mark Selby, CEO of Canada Nickel Company. "Ausenco brings extensive experience to the project, having partnered with us since the completion of a Preliminary Economic Assessment in 2020, the Feasibility Study in 2023, and front-end engineering design in 2025."Ausenco has played a key role in the successful delivery of the Detour Gold project in this region and brings proven experience delivering large-scale greenfield processing plants in Ontario. Canada Nickel Company is building an Integrated Project Team to lead delivery of the Crawford Nickel Project.Bravo Mining (TSXV: BRVO) (OTCQX: BRVMF) has welcomed the publication of Presidential Decree No. 12,823 signed by President Luiz Inácio Lula da Silva formally creating the Export Processing Zone of Barcarena in the Municipality of Barcarena, State of Pará. Bravo Mining has been selected to anchor the ZPE Barcarena, becoming the first mineral project ever designated as an anchor tenant of a Brazilian ZPE."The signing of the Presidential Decree formally creating the ZPE Barcarena is a significant milestone for Bravo Mining and materially advances regulatory certainty around our development scenario," said Luís Azevedo, Chairman and CEO of Bravo Mining. "Coming on the heels of the recent closing of our oversubscribed equity financing for net proceeds of ~C$81.8 million, completed amid strong investor demand and an improving PGM price environment, with the 4PGE basket price now approximately 60% higher than the price used in our PEA, this development further reinforces our confidence in the long-term strategic positioning of the Luanga Project."The publication strengthens the company's Alternate Case development scenario detailed in its Preliminary Economic Assessment which contemplates use of the ZPE Barcarena fiscal framework to enable local processing and vertical integration of metals potentially produced from the Luanga palladium, platinum, rhodium, gold and nickel project. The ZPE provides access to structural benefits including potential capital and operating cost savings through exemptions on imported equipment and tax-advantaged export treatment.Article Source: https://equity-insider.com/2026/01/12/the-only-silver-that-matters-now-is-silver-you-can-touch/ CONTACT:Equity Insider
