Selkirk Copper's Final Phase 1 Drill Program Results Deliver High-Grade Mineralization Intersected Across Five Target Areas, and Rapid Progress on the Phase 2 Drill ProgramJune 3, 2026 7:00 AM
NewsfileHighlightsDrilling at Area 118 has confirmed discovery of the high-grade 301 Lens beneath previous drilling:4.39% Cu, 7.60 g/t Au, and 21.07 g/t Ag (10.22% CuEq) over 4.1 m, within a broader interval of 1.56% Cu, 2.26 g/t Au, and 7.63 g/t Ag (3.31% CuEq) over 15.7 m, from 278.6 m in 26SCM157Within this interval, individual one-meter bornite-rich samples returned grades as high as 4.6% Cu, 23.1 g/t Au, and 26.4 g/t Ag.Drilling at Minto East continues to intersect high-grade mineralization beneath the limits of previous drilling:3.77% Cu, 6.74 g/t Au, and 23.68 g/t Ag (8.99% CuEq) over 3.8 m, within a broader interval of 1.38% Cu, 2.34 g/t Au, and 8.67 g/t Ag (3.20% CuEq) over 11.3 m, from 639.7 m in 26SCM134Drilling at the 117 Lens beneath the Area 2 Pit has intersected broad zones of copper-gold-silver mineralization as well as high grade intervals, including:2.93% Cu, 1.50 g/t Au, and 16.37 g/t Ag (4.19% CuEq) over 5.0 m, from 325.4 m in 26SCM1420.63% Cu, 0.08 g/t Au, and 1.74 g/t Ag (0.70% CuEq) over 47.9 m, from 348.1 m in 26SCM167Drilling at Minto North continues to delineate high-grade mineralization in the 202 Lens:3.56% Cu, 2.34 g/t Au, and 21.42 g/t Ag (5.48% CuEq) over 3.7 m, within a broader interval of 0.89% Cu, 0.49 g/t Au, and 4.84 g/t Ag (1.29% CuEq) over 21.7 m, from 195 m in 26SCM131Drilling at Ridgetop continues to intersect broad intervals of near-surface mineralization: 0.46% Cu, 0.14 g/t Au, and 1.57 g/t Ag (0.58% CuEq) over 69.6 m, from 13.7 m in 26SCM137The 50,000 metre Phase 2 drill program is advancing rapidly, with 14,000 metres completed during the first month of drilling. Drilling productivity is averaging 120 metres per day per drill, with four drills active currently. This program is focused on resource expansion, infill drilling, geotechnical drilling, and geometallurgical data collection.Vancouver, British Columbia and Pelly Crossing, Yukon--(Newsfile Corp. - June 3, 2026) - Selkirk Copper Mines Inc. (TSXV: SCMI) (FSE: IO20) (OTCQB: SKRKF) ("Selkirk Copper" or the "Company") is pleased to announce final results from the Phase 1 drill program which was conducted between August 2025 and April 2026, as well as rapid progress on the Phase 2 drill program which was initiated in May 2026, at the Minto Project in Yukon, Canada. M. Colin Joudrie, President & CEO, commented: "The Phase 1 drill program has achieved exceptional results at each of the five primary target areas within the mine footprint – expanding known zones of mineralization, discovering several higher grade copper-gold-silver intervals within known zones, discovering several new lenses of high grade mineralization, and discovering mineralization at depths previously undrilled. The team successfully completed the largest drill program in the Yukon over the last ten years and did so safely, on-budget, and on-schedule through one of the coldest falls and winters on record. These results are being incorporated into an updated Mineral Resource Estimate and Preliminary Economic Assessment that remains on track for completion in mid-2026."We could not have asked for a better start to the 50,000 meter Phase 2 drill program with drill productivity exceeding already high performance from the Phase 1 drill program. The Phase 2 program is designed to inform a planned feasibility study in-fill drilling, resource definition, integrated mine planning, economic studies, and refinements to the restart development opportunity. The Phase 1 program has proven that there is still significant discovery potential in the near-mine environment, and supports our view that our commitment to the Phase 2 program, along with the first significant district and regional exploration in over a generation to be carried out this summer, will continue to deliver meaningful positive results for the Minto Project".2025-2026 Phase 1 Drill Program ResultsReported here is the final batch of results from the Phase 1 drill program that was completed earlier this year. This includes assay results from forty-six (46) holes drilled between February and March 2026.Figure 1: Plan view of the Minto Mine Property area showing surface projections of mineralized zones relative to Phase 1 and Phase 2 drill collars.To view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/11605/299936_figureone.jpgArea 118 and the 301 LensArea 118 hosts near-surface resources on a hillside that is located south of previous open pit mining. This area became a priority for exploration due to recognition of anomalous drill intercepts that had not been adequately followed-up beneath the known near-surface resources. Recognition of the additional potential at this target resulted from geological modelling and detailed data review completed by Selkirk Copper during early 2026. Reported here are eight holes from Area 118, seven of which intersected significant mineralization.The drilling completed at Area 118 has confirmed discovery of a high-grade mineralized lens at depth beneath the previously known resources in this area. This new discovery of mineralization at depth has been designated the 301 Lens. The 301 Lens is located between 100 and 140 metres below previously known resources in this area potentially repeating a pattern of stacked lenses of mineralization intersected elsewhere on the mine property. This lens has been intersected by widely spaced drill holes over an area approximately 500 x 300 metres, with thicknesses ranging from 4 to 20 metres thick.Mineralization within this area is characterized by bornite and chalcopyrite mineralization hosted within foliated and migmatized granodiorite. Bornite mineralization is associated with higher copper and gold grades, and thicker mineralized intervals. Locally, bornite mineralization occurs in coarse blebs up to 3 cm wide comprising up to 5% of the volume of the rock. These intervals can host high grades, such as the intercept from drill hole 26SCM157 which returned 1.56% Cu, 2.26 g/t Au, and 7.63 g/t Ag (3.31% CuEq) over 15.7 m. Within this interval, individual one-meter bornite-rich samples returned grades as high as 4.6% Cu, 23.1 g/t Au, and 26.4 g/t Ag. These gold and silver grades rank amongst the highest precious metal concentrations observed within all previous drilling at Minto, within a database of 163,000 historical samples. The discovery of additional mineralization in Area 118 and the 301 Lens represents an important opportunity for resource expansion. New drill intercepts are located within 300 meters of previous underground development, providing an opportunity for future mining at relatively low cost. Additional drilling of this area is planned as part of the Phase 2 drill program.Figure 2: Cross section view looking east showing recently discovered mineralization within the 301 Lens and 117 Lens, located in proximity to areas of previous underground mining.To view an enhanced version of this graphic, please visit:

https://images.newsfilecorp.com/files/11605/299936_figurethree.jpg117 LensIn central part of the Mine area, recent drilling has delineated mineralization underground in an area between two historical open pits, the Minto Main Pit and the Area 2 Pit. The discovery of mineralization at depth in this area has been designated the 117 Lens. Reported here are eight holes from the Minto Main area, all of which intersected significant mineralization. Mineralization within this area includes broad intervals of chalcopyrite mineralization, ranging from 20 – 90 metres thick with weighted average grades ranging from 0.3 – 0.7% copper. Narrower zones of higher-grade mineralization also occur within this area, such as in hole 26SCM142 which intersected 2.93% Cu, 1.50 g/t Au, and 16.37 g/t Ag (4.19% CuEq) over 5.0 m. Initial drilling of the 117 Lens is still relatively widely spaced, and more work is planned to understand the controls on high grade mineralization within the broader mineralized domain.Mineralization in the 117 Lens has been delineated over an area approximately 300 by 250 metres and remains open to the west. Also reported here is 26SCM168, one of the last holes of the Phase 1 drill program and a 150-metre step-out westwards from previous drilling in this area. This hole intersected 47.9 m grading 0.63% Cu, 0.08 g/t Au, and 1.74 g/t Ag (0.70% CuEq) and indicates potential for further expansion of the 117 Lens. Additional drilling of this area is planned as part of the Phase 2 drill program. Minto EastDrilling at Minto East targeted expansion of several stacked mineralized lenses, with a focus of expansion northwards and southwards from previously known resources. Reported here are eight holes from the Minto East area, five of which intersected significant mineralization. Three holes failed to intersect mineralization on the eastern and western edges of the Minto East zone, however mineralization remains open in some areas to the north and to the south.Hole 26SCM125 represents a relatively typical example of mineralization at Minto East, with three significant mineralized intercepts spaced approximately 100 m apart, including 1.4 m grading 11.23% CuEq at 211 m, 2.7m grading 5.41% CuEq at 336 m, and 4.8m grading 1.51% CuEq at 438 m (detailed assays in Table 2). The lower-most of these significant intercepts is located within 50 metres of historical underground workings, at the same elevation, providing an opportunity for future extraction at relatively low cost. Also reported from Minto East is hole 26SCM134 which intersected 3.77% Cu, 6.74 g/t Au, and 23.68 g/t Ag (8.99% CuEq) over 3.8 m, within a broader interval of 1.38% Cu, 2.34 g/t Au, and 8.67 g/t Ag (3.20% CuEq) over 11.3 m, from 639.7 m. Mineralization within this interval is characterized by folioform chalcopyrite and blebby disseminated bornite hosted within migmatized granodiorite. This hole represents the deepest intercept of high-grade mineralization that has ever been drilled at Minto; most previous drilling was limited to less than 500 metres below surface, and no comparable high-grade mineralization has previously been intersected beyond 550 metres below surface. Additional drilling is contemplated for this area once the underground workings are accessible.Figure 4: Cross section view looking west highlighting drill holes from the Phase 1 program that intersected mineralization at depth beneath previous underground mining areas.To view an enhanced version of this graphic, please visit:

https://images.newsfilecorp.com/files/11605/299936_figurefive.jpgRidgetopDrilling at Ridgetop was a significant focus throughout the Phase 1 drill program. This drilling targeted shallow mineralization that can potentially be mined via an open pit at a lower cut-off grade. Reported here are six holes from Ridgetop, five of which intersected significant mineralization. Mineralization at Ridgetop is typically characterized by a series of closely spaced, sub-parallel mineralized lenses that are typically 5 – 15 metres thick. In some areas, multiple mineralized lenses occur in proximity and result in thicker mineralized intervals. Drill hole 26SCM137 represents an example of this thicker, more continuous mineralization with an intersection of 0.46% Cu, 0.14 g/t Au, and 1.57 g/t Ag (0.58% CuEq) over 69.6 m, from 13.7 m. This mineralization begins at the top of bedrock beneath a thin veneer of overburden and represents a potential opportunity for extraction early in the mine life with minimal waste stripping. Minto NorthDrilling at Minto North was a major focus throughout the Phase 1 drill program, including focus on the expansion and delineation of the Minto North west zone. Reported here are results from eight holes from Minto North, four of which intersected significant mineralization. The Minto North west zone returned some of the highest grade and highest thickness drill intercepts during the Phase 1 drill program. Mineralization occurs within a lens-shaped area that is approximately 300 x 400 m, and up to 30 m thick. High-grade copper, gold, and silver grades are associated with blebby, folioform, net-textured, and semi-massive bornite and chalcopyrite mineralization. This area has been designated as the 202 Lens for purposes of geological modelling and resource estimation and is notably higher-grade than other parts of Minto North.Drill results reported here targeted the periphery of the 202 Lens and are generally lower grade than some results from this zone that were reported earlier during the Phase 1 drill program. Drill hole 26SCM131 is a notable exception and represents the high tenor of mineralization that occurs within the central portion of the 202 Lens. This hole intercepted 5.48% CuEq over 3.7 m, within a broader interval of 1.29% CuEq over 21.7 m, from 195 m (detailed assays in Table 2). Other holes reported here intersected thinner and lower grade intervals around the periphery of the 202 Lens. Four holes tested beyond the limits of the mineralized lens and failed to intersect significant mineralization; however, these holes do provide important information to constrain resource estimation and mine planning. Drilling in Other AreasReported here also is one drill hole from the Copper Keel area and two drill holes from an Exploration target called Trapline.At Copper Keel, drill hole 26SCM158 was a 50-metre step out northwards from resources that were previously delineated in this area. This hole returned an intersection of 0.53% Cu, 0.29 g/t Au, 2.18 g/t Ag (0.77% CuEq) over 9.9 metres. Other step-out drilling in this area failed to intersect significant mineralization. Results from drilling in this area suggest that further resource expansion potential at the north end of Copper Keel is limited. Trapline is a new name proposed for the northern half of the Minto claim block. This area is considered prospective for continuation of the mineralized trends observed within the Minto Project area. The Trapline area includes numerous geophysical and geochemical targets resulting from work by previous operators. During the 2025-2026 drill program, two drill holes totaling 750 metres were completed to test geophysical anomalies in the Trapline area.The first hole, 26SCM163, targeted an area containing several coincident geophysical anomalies, characterized by a conductive magneto-telluric (MT) response, a magnetic high response, and a moderate chargeability response. This area also contained weakly anomalous copper in soil values. This drillhole intersected foliated granodiorite, assimilation textures, and a narrow 4 m interval containing folioform chalcopyrite. Assay results were sub-economic and the drill hole is considered a "near-miss" that may warrant follow-up. The second hole, 26SCM167, targeted a northwest-trending magnetic high associated with a moderate chargeability feature at depth. This drill hole intersected foliated granodiorite and assimilation textures but did not intersect any sulphide mineralization. There were no obvious lithological features observed in this hole to explain the geophysical anomalies in this area.The results of this exploration drilling at Trapline demonstrate that further evaluation of geological and geophysical datasets is needed to guide exploration drilling in this area. Physical property samples and lithogeochemical samples were collected from these drill holes, and the results of these analyses may help inform future exploration. Additional geophysical surveys, geological mapping, and geochemical sampling will also help with identifying future exploration targets within the northern half of the Minto claim block.

Recoveries as estimated from historical mineral processing results. 2026 Phase 2 Drill ProgramFour drill rigs are active on the Phase 2 drill program, which commenced on May 1, 2026. This drill program is targeting approximately 50,000 metres with a focus on resource expansion, infill drilling, geotechnical drilling, and geometallurgical data collection to support increased resource confidence and mine planning for planned feasibility study work. Drilling productivity has been significantly higher than expected throughout the first month of the Phase 2 drill program. Daily drill productivity is currently averaging 120 metres per day, compared to 94 metres per day during the Phase 1 program. The team on site is ramping up to handle the increased productivity, with hiring and training of new staff, and obtaining additional equipment and supplies. As of June 1, 14,000 metres of drilling has been completed in 59 holes, comprising 28% of the planned 50,000 metres. Drilling has focused on resource expansion and infill at several locations within the deposit area, including Minto North, Copper Keel, Minto Main (117 Lens) and Area 118 (301 Lens). The first batches of samples have been shipped off site for laboratory analysis, and initial assay results are expected within eight weeks. Results from the Phase 2 program are expected to be released throughout the summer and fall of 2026.Marketing ServicesFurther to the Company's news release dated December 1, 2025 and subject to the approval of the TSX Venture Exchange, the Company has renewed its marketing services agreement with Triomphe Holdings Ltd., doing business as Capital Analytica (“Capital Analytica”), for an additional six-month term at a cost of $75,000, which was paid on May 27, 2026.

Following data collection, core is cut along the long axis, with half of the core going to the lab for chemical analysis and the remaining half kept in sequence as record. The half core samples are packaged with the corresponding sample tag id and sealed. All sampling is conducted by Selkirk Copper Mines Inc. and subject to Company standard internal quality control and quality assurance (QAQC) programs which include the insertion of certified reference material, coarse blank materials, and field duplicate analysis, on top of the standard laboratory QAQC procedures to monitor contamination during preparation and analytical accuracy and precision. QAQC insertion rates approximate 15% of all samples at set intervals. For the 2025 program all samples were sent to ALS Laboratory's prep laboratory in Whitehorse, YK, then shipped to ALS Vancouver for gold fire assay and four-acid multi-element analysis. All samples are prepared by crushing rock to 70% passing 2mm screen, then splitting a 250g sub-sample using a riffle splitter before being pulverized 85% passing 75 microns. Gold is analyzed by 30 g Fire Assay (Au-AA23) with atomic absorption (AAS) analysis followed by gravimetric finish for overlimit results. Copper is analyzed by four-acid digest (ME-ICP61) with inductivity coupled plasma – atomic emission spectroscopy (ICP-AES) finish. If copper overlimit results are triggered a second four-acid digest for high grade copper (Cu-OG62) is conducted. Samples containing greater than 1000 ppm copper are also analyzed for soluble copper using a sulphuric acid leach (Cu-AA05) analysis with AAS finish is performed. ALS Vancouver holds an ISO/IEC 17025 standard accreditation.QAQC results are reviewed open receipt of results. Overall QAQC results show strong analytical performance across Cu, Au, and Ag datasets. All control standards are within acceptable tolerance, with no significant outliers or systematic bias observed. Primary intervals are reported as drill core length, with true widths estimated to be approximately 90% of core lengths, based on the sub-horizontal to shallow-dipping nature of the modelled mineralized zones.

Selkirk Copper Discovers a New Mineralized Zone and Commences a Phase 2 Drill Program Targeting 50,000 Additional MetresMay 11, 2026 7:00 AM
NewsfileHighlightsA new mineralized zone, the 117 Lens, has been discovered beneath a previously mined open pit. Initial results indicate broad zones of copper-gold-silver mineralization, including:1.27% Cu, 0.89 g/t Au, and 5.91 g/t Ag (1.98% CuEq) over 12.6 m, within a broader interval of 0.41% Cu, 0.38 g/t Au, and 3.92 g/t Ag (0.58% CuEq) over 86.8 m, from 244.2 m in 26SCM126.Drilling at Minto East continues to intersect multiple lenses of high-grade mineralization:2.36% Cu, 0.85 g/t Au and 5.44 g/t Ag (3.04% CuEq) over 5.8 m, from 241.7 m, and a second mineralized intercept of 2.57% Cu, 0.66 g/t Au and 7.66 g/t Ag (3.13% CuEq) over 9.1 m, from 476 m in 26SCM128. Assay results from the Phase 1 drill program, completed in April, continue to delineate high-grade copper-gold-silver mineralization. Assay results have been released for approximately 78% of the Phase 1 drill program, with the remaining results expected to be released over the next month.As of May 1, Selkirk Copper has commenced its Phase 2 drill program, targeting up to an additional 50,000 metres to be completed during 2026. This drill program will continue to focus on resource expansion, while including infill drilling, geotechnical drilling, and geometallurgical data collection to support increased resource confidence and mine planning, all of which will inform planned feasibility study work. Vancouver, British Columbia and Pelly Crossing, Yukon--(Newsfile Corp. - May 11, 2026) - Selkirk Copper Mines Inc. (TSXV: SCMI) (FSE: IO20) (OTCQB: SKRKF) ("Selkirk Copper" or the "Company") is pleased to announce commencement of the Phase 2 drill program and additional drill results from the Phase 1 drill program at the Minto Mine in Yukon, Canada. M. Colin Joudrie, President & CEO, commented: "We are very pleased to announce the resumption of drilling and a significant Phase 2 drill program planned for 2026 that will build upon our successful Phase 1 drill program that was completed earlier this year. With the updated Mineral Resource Estimate and Preliminary Economic Assessment on track for completion in mid-2026, we are looking ahead towards additional requirements that will support a potential restart decision in mid-2027. The Phase 2 drill program will continue to focus on resource expansion while also prioritizing important geoscience and technical data collection that will support the restart decision. "Additionally, we are pleased that drilling continues to deliver positive results, including discovery of new mineralized zones located nearby to existing resource areas and adjacent to underground mine infrastructure and potential open pit locations. These results highlight that there is still significant discovery potential in the near-mine environment, and support our view that our commitment to exploration drilling will continue to deliver meaningful positive results."2026 Phase 2 Drill ProgramDrilling has commenced at the Minto Mine site for the Phase 2 drill program. This drill program is targeting up to 50,000 metres to be completed by November 2026. Drilling will continue to focus on resource expansion, while also prioritizing infill drilling, geotechnical drilling, and geometallurgical data collection to support increased resource confidence and mine planning for planned feasibility study work. Two drill rigs are active currently, with two additional rigs expected to commence drilling in the coming week. The drill program will be supported by the same team that successfully completed the Phase 1 drill program in 2025-2026, including Omineca Diamond Drilling Ltd. and Selkirk Copper's staff and exploration contractors. Geotechnical and geometallurgical objectives for the Phase 2 drill program are being developed in collaboration with Selkirk Copper's team of technical consultants. Resource expansion drilling will focus on further delineation and expansion of the most successful target areas identified during the Phase 1 drill program, including Minto North, Area 118, Ridgetop, and the 117 Lens. Exploration drilling will also include initial tests of new geophysical targets identified from historical magnetic and IP surveys. Additionally, planning is underway for exploration field activities this summer, with a focus on geological mapping and prospecting to identify new target areas and investigate known mineral occurrences within mineral claims owned by Selkirk Copper. Geological mapping is considered a fundamental dataset to guide subsequent exploration activities, and there is no record of geological mapping for many locations within the extensive mineral claims controlled by Selkirk Copper. In other locations, detailed geological mapping completed in the 1970s identified several "Minto-style" copper-gold-silver mineral occurrences that appear to have had no substantial follow-up. The team will employ a boots-on-the-ground approach to locate and validate these mineral occurrences and prioritize them for future evaluation including exploration drilling. 2025-2026 Phase 1 Drill Program ResultsAll samples from the Phase 1 drill program have been shipped from site. Near the end of the Phase 1 program, samples were shipped to two different ALS prep facilities in Whitehorse and Langley to minimize turnaround time. Reported here are assay results from eighteen (18) holes drilled between November 2025 and January 2026. Assay results have been released for approximately 78% of the Phase 1 drill program, with the remaining results expected to be released over the next month.Figure 1: Plan view of the Minto Mine Property area showing surface projections of mineralized zones relative to Phase 1 drill collars (orange and yellow circles).

https://images.newsfilecorp.com/files/11605/296870_figure%201.jpg117 LensStep-out drilling from historical drill intercepts has discovered a new mineralized lens located below the Area 2 open pit which is located just below the Minto Main label in Figure 1. Reported here are three holes that targeted the 117 Lens, all of which intersected significant mineralization.Mineralization in the 117 Lens is characterized by disseminated to folioform chalcopyrite and bornite, hosted in foliated granodiorite. Intense potassic alteration is also associated with mineralization, including orthoclase, biotite, and magnetite. Initial drill results indicate that the 117 Lens hosts broad intervals of moderate-grade mineralization and local areas of higher grades, such as 26SCM126 which intersected 1.27% Cu, 0.89 g/t Au and 5.91 g/t Ag (1.98% CuEq) over 12.6 m, within a broader interval of 0.58% CuEq over 86.8 m. The grade of mineralization correlates with intensity of foliation, with higher grades occurring in areas of more intense deformation. Initial drilling has delineated the 117 Lens as a tabular zone extending over an area of 250 by 200 metres and dipping gently to the north. Mineralization is located within 200 meters of previous underground development, suggesting low development costs would be required to access this zone. Assay results are pending for several additional holes targeting the 117 Lens, and mineralization in this area remains open to the west.Figure 2: Cross section looking east, showing the recently discovered 117 Lens located beneath the Area 2 open pit and between two areas of previous underground mining.To view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/11605/296870_figure%202.jpgMinto East and Copper KeelDrilling at Minto East targeted expansion of several stacked mineralized lenses, with a focus of expansion northwards and southwards from previously known resources. Reported here are two holes from Minto East, both of which intersected significant mineralization in step-outs from previous drilling.Drill hole 26SCM128 stepped out 70 metres from historical drilling and intersected a series of four mineralized lenses between 240 and 480 metres downhole. Each lens is characterized by foliated granodiorite and migmatite, with high-grade chalcopyrite-bornite mineralization. The elevation, mineralogy, and texture of these mineralized lenses correspond well with previously drill intercepts, suggesting continuity of the mineralized zone into this area. Additionally, a fifth mineralized lens was intersected at depth, beyond the extents of previous drilling, indicating potential to continue delineating new resources at depth. Drill hole 26SCM146 stepped out an additional 50 metres beyond 26SCM128. This hole also intersected several mineralized lenses at similar elevations as hole 26SCM128, suggesting geological continuity. However, the grade of mineralization intersected in 26SCM146 was lower than 26SCM128. Additional drill results are pending in this area which will better describe and delineate the extents of high-grade mineralization.Figure 3: Cross section looking north, showing recent drill results at Minto East that expand the extents of several mineralized lenses to the west and northwest. Also highlighted is discovery of a potential new mineralized lens at depth.To view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/11605/296870_figure%203.jpgAdditionally, reported here are two holes drilled northwards from the Copper Keel area, targeting the gap between Minto East and Copper Keel. Both of these holes intersected foliated granodiorite and low-grade chalcopyrite mineralization at the target depth, however neither hole produced a significant intercept. The team will continue to review geological and structural data to evaluate a potential linkage of the mineralized trends between Copper Keel and Minto East.Figure 4: Detailed photographs of high-grade mineralization in drill core from Minto East and the 117 Lens, showing a variety of sulphide textures including folioform, semi-massive, and massive chalcopyrite-bornite.To view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/11605/296870_figure%204.jpgMinto NorthDrilling at Minto North was a major focus throughout the Phase 1 drill program, with drilling in the later portion of the program focused on delineating the peripheral limits of this high-grade mineralized zone. Reported here are results from four additional holes at Minto North, all of which intersected significant mineralization. The holes from Minto North reported here are generally lower grade than some previous results in this area. These lower grade areas are characterized by a decrease in bornite and chalcopyrite, decreased intensity of migmatite textures, and decrease in overall thickness. This information will continue to support the development of a geological model for the Minto North area and support updated mineral resource estimation and mine planning studies. Ridgetop and Area 118Drilling at Ridgetop and Area 118 was a significant focus throughout the Phase 1 drill program. This drilling targeted shallow mineralization that can potentially be mined with an open pit at a lower cut-off grade. Reported here are seven holes from Ridgetop and Area 118, five of which intersected significant mineralization. Results from these holes include mineralized intercepts grading between 0.4 - 0.9% CuEq, which is above the cutoff grade of 0.3% CuEq over 5 metres that was used for the 2025 mineral resource estimation. Additional results from Ridgetop and Area 118 are pending.

Recoveries as estimated from historical mineral processing results. QAQC Procedures and Data ValidationThe Company is drilling NQ sized core. Following data collection, core is cut along the long axis, with half of the core going to the lab for chemical analysis and the remaining half kept in sequence as record. The half core samples are packaged with the corresponding sample tag id and sealed. All sampling is conducted by Selkirk Copper Mines Inc. and subject to Company standard internal quality control and quality assurance (QAQC) programs which include the insertion of certified reference material, coarse blank materials, and field duplicate analysis, on top of the standard laboratory QAQC procedures to monitor contamination during preparation and analytical accuracy and precision. QAQC insertion rates approximate 15% of all samples at set intervals. For the 2025 program all samples were sent to ALS Laboratory's prep laboratory in Whitehorse, YK, then shipped to ALS Vancouver for gold fire assay and four-acid multi-element analysis. All samples are prepared by crushing rock to 70% passing 2mm screen, then splitting a 250g sub-sample using a riffle splitter before being pulverized 85% passing 75 microns. Gold is analyzed by 30 g Fire Assay (Au-AA23) with atomic absorption (AAS) analysis followed by gravimetric finish for overlimit results. Copper is analyzed by four-acid digest (ME-ICP61) with inductivity coupled plasma - atomic emission spectroscopy (ICP-AES) finish. If Cu overlimit results are triggered a second four-acid digest for high grade copper (Cu-OG62) is conducted. For any samples where oxide copper minerals are identified, a sulphuric acid leach (Cu-AA05) analysis with AAS finish is performed. ALS Vancouver holds an ISO/IEC 17025 standard accreditation.QAQC results are reviewed open receipt of results. Overall QAQC results show strong analytical performance across Cu, Au, and Ag datasets. All control standards are within acceptable tolerance, with no significant outliers or systematic bias observed. Primary intervals are reported as drill core length, with true widths estimated to be approximately 90% of core lengths, based on the sub-horizontal to shallow-dipping nature of the modelled mineralized zones.

Selkirk Copper Reports Additional Intersections of High-Grade Cu-Au-Ag From the Phase 1 Drill Program at the Minto Copper-Gold-Silver MineApril 30, 2026 7:00 AM
NewsfileHighlightsDrilling at Minto North continues to deliver broad intervals of high-grade mineralization:
4.19% Cu, 2.50 g/t Au and 21.15 g/t Ag (6.2% CuEq) over 14.7 m, within a broader zone of 2.58% Cu, 1.50 g/t Au and 12.67 g/t Ag (3.8% CuEq) over 26.8 m from 177.9 m in drill hole 25SCM052.Drilling at Area 118 intersects high-grade Cu-Au-Ag mineralization at shallow depths. Subsequent drilling will prioritize follow-up in this area:
6.60% Cu, 5.18 g/t Au and 27.02 g/t Ag (8.3% CuEq) over 6.6 m, from 64 m in drill hole 25SCM098.2.68% Cu, 1.81 g/t Au and 11.91 g/t Ag (4.1% CuEq) over 14.4 m, from 79.2 m in drill hole 25SCM090.Drilling at Ridgetop South intersects high-grade mineralization at shallow depths in a 100-metre step-out beyond previous drilling:
2.75% Cu, 0.77 g/t Au and 10.86 g/t Ag (3.4% CuEq) over 5.7 m, from 99 m in drill hole 25SCM089.Vancouver, British Columbia and Pelly Crossing, Yukon--(Newsfile Corp. - April 30, 2026) - Selkirk Copper Mines Inc. (TSXV: SCMI) (FSE: IO20) (OTCQB: SKRKF) ("Selkirk Copper" or the "Company") is pleased to announce new assay results from the recently completed Phase 1 Drilling Program at the Minto Mine in Yukon, Canada. M. Colin Joudrie, President & CEO, commented: "We are very encouraged by the consistently high-grade results coming out of the Minto North west zones, which continue to demonstrate both continuity and strength of mineralization. Equally important is the confidence the exploration team has built through recent geological advancements which has allowed us to successfully execute large, 100-metre step-outs at Ridgetop and Area 118, each of which have delivered high grade intersections at shallow depths which are amenable to open pit extraction. Further, the exploration team's detailed review of historical data has directly contributed to the targeting of Area 118, where we've intersected one of the higher-grade zones encountered in our 2025 Phase 1 program. We fully expect the integration of these results to enhance our evolving geological understanding at Minto and to positively contribute to mine plans being developed as part of our Preliminary Economic Assessment, on-track for delivery mid-year." Phase 1 Drill Program 2025-2026Selkirk Copper has successfully completed its Phase 1 drill program, comprising 52,288 m of drilling in 175 holes. Drilling was conducted between August 2025 and March 2026 with four diamond drill rigs. This represents one of the largest drilling programs completed in Yukon in the last ten years. Drilling was completed safely, with no medical aid or lost-time injuries, and minimal downtime. Drilling productivity was very high, including individual drills producing more than 200 metres per day in some instances, with an average of 94 metres per day per drill throughout the entire program. High productivity and relatively low cost-per-metre enabled us to surpass the originally planned 50,000 m program, resulting in completion of 105% of the initial plan.Reported here are assay results from holes drilled in November and December 2025 (Figure 1). Results from approximately 63% of the Phase 1 drill program have now been released. The company expects to continue releasing assay results from the Phase 1 drill program as they are received throughout the first half of 2026.Table 1: Drilling by ZoneZoneHoles completedMetres drilledMinto North4313,613Ridgetop6813,940Minto East239,952Copper Keel103,475118195,648Minto Main125,660Total17552,288 Figure 1: Plan view of the Minto Mine showing surface projections of mineralization zones (Ridgetop (yellow), Copper Keel (green), 118 (blue), Minto East (purple) and Minto North (red)), relative to Phase 1 drill collars (yellow circles).

https://images.newsfilecorp.com/files/11605/295131_s_image2.jpgDrill ResultsMinto NorthDrilling at the Minto North zone continues to delineate the extents of high-grade mineralization in this area. Reported here are five drill holes from the Minto North west lens, three of which intersected significant mineralization. Recent drilling and geological modelling has defined the limits of this lens in most directions, although mineralization remains open to the south. Drill results reported here include 25SCM052, which was drilled in late October, 2025. Release of results from this hole were delayed due to necessary reanalysis flagged by our check-assay protocols. Selkirk Copper maintains rigorous QAQC procedures designed to monitor analytical accuracy, precision, sample handling, and potential contamination during preparation. In this instance, the QAQC procedures worked to identify a potential sample preparation concern, triggering a targeted reanalysis, leading to a collaborative review that identified opportunities to improve workflow for sample preparation. The final results for hole 25SCM052 include an intercept of 6.2% CuEq over 14.7 m, within a broader zone of 3.8% CuEq over 26.8 m. This represents one of the highest-grade intersections within the Phase 1 drill program and highlights the importance of rigorous QAQC procedures to ensure these results can be incorporated with confidence into future resource estimation and mine planning. An example of the high-grade mineralization in 25SCM052 is included as one of the photographs in Figure 2 above.Area 118Drilling at Area 118 initially focused on exploring historical (2007, 2011-2012) high-grade results south of the current 118 resource. These historical results indicated a potential for shallow near-surface mineralization. During the initial drilling, a new mineralized lens was discovered 130 metres beneath the original target area (Figure 3). Reported here are six drill holes targeting the upper mineralized lens in Area 118, five of which intersected significant mineralization. Additional drill results from the newly discovered lens at depth in Area 118 are pending.Recent drill results include 25SCM090 and 25SCM098. Both holes intersected very high-grade mineralization at shallow depths, stepping out 50 m from historical drilling. Hole 25SCM098, which assayed at 6.60% Cu, 5.18g/t Au, and 27.02g/t Ag (8.3% CuEq) over 6.6 m, ranks in the top 98th percentile for copper equivalent grade compared to all drilling within the Minto database, which spans six decades and includes more than 1,400 drill holes and more than 4,300 significant intercepts.Mineralization in Area 118 is hosted within strongly deformed, migmatized rock containing disseminated and folioform chalcopyrite and bornite. Migmatite foliation and mineralized lenses dip gently to the north. The upper mineralized lens, including new drill intercepts reported here, extends along strike over 700 metres and remains open to the west. During the winter, accessing additional drill sites further west in this area was challenging due to locally steep terrain and icy conditions. Additional drilling is planned to further delineate this near-surface, high-grade target.Figure 3: Plan view and accompanying cross sections of the 118 zone.To view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/11605/295131_s_image3.jpgRidgetop SouthDrilling at Ridgetop during the Phase 1 drill program focused on expansion of near-surface mineralized lenses, particularly to the southwest of the proposed open pit (Figure 4). Drill plans at Ridgetop evolved iteratively throughout the Phase 1 drill program as results were received. Reported here are seventeen drill holes targeting resource expansion at the Ridgetop zone, fourteen of which intersected significant mineralization.Figure 4: Plan view of the Ridgetop South drilling, highlighting select significant intervals.To view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/11605/295131_s_image4.jpgAssay intervals reported here from Ridgetop grade between 0.3 - 1.0% Cu, with thickness ranging from 5 - 18 metres. These intervals are above the 2025 MRE open pit cut-off grade of 0.30% CuEq. The majority of mineralized intercepts reported here are less than 50 meters below surface. Continuity of mineralization between drill holes is relatively high, with several stacked, closely spaced mineralized lenses extending over an area measuring 700 x 400 metres.Mineralization at Ridgetop remains open to the southwest. Drill hole 25SCM089, reported here, represents a 100 m step-out to the southwest of previous drilling. This hole intersected two mineralized intervals, including 1.29% CuEq over 11.9 m, from 35 metres below surface, and 3.4% CuEq over 5.7 m, from 99 m below surface. The high grades intersected in this hole are much higher than typical for the Ridgetop deposit, and more drilling is planned to investigate further to the southwest. Minto EastDrilling at Minto East continues to delineate a series of stacked, sub-horizontal lenses which are a target for underground mining. Reported here are three drill holes at Minto East, each of which stepped-out approximately 75 m beyond previous drilling on the western side of this target area. In each of these holes, moderate-grade mineralization was intersected, with the best result in 25SCM092 which intersected 1.07% CuEq over 6.3 m. Results from these holes indicate geological continuity of the mineralized lenses but marginal grades for underground mining in this location. Results from these drill holes have been used to guide exploration drilling towards other more prospective parts of the Minto East target.The location, azimuth, dip and depth of hole of drill holes reported here are summarized in Table 2 and significant intervals are summarized in Table 3.Table 2: Collar Locations and Header InformationHole IDEastingNorthingAziDipEOH (m)Zones25SCM052383888694594760-88.5291Minto North25SCM057384507694378965-70354Area 11825SCM072384408694374565-75291Area 11825SCM07338502269433790-90552RT South25SCM08338493769433130-90402RT South25SCM08438486169433330-90135RT South25SCM0863838866945952186-63327Minto North25SCM08838499369433160-90150RT South25SCM08938477469433490-90174RT South25SCM0903844276943880270-75264Area 11825SCM09138478769434080-90174Ridgetop25SCM0923851486945269295-80543Minto East25SCM093383883694594922963252Minto North25SCM09538483969434830-90150RT South25SCM098384426694388190-75300Area 11825SCM09938506369433400-90162RT South25SCM1003843516943925290-65297Area 11825SCM10138512269433210-90153RT South25SCM10238514669433780-90210RT South25SCM103A38497169451400-90363Minto East25SCM1043851386943405270-70150RT South25SCM10538486169436120-90270RT South25SCM1063841156945836135-72300Minto North25SCM10738511169433820-90174RT South25SCM10838518369433310-90129RT South25SCM10938487469435860-90173.7RT South25SCM11038496969451460-70357Minto East25SCM11138522869433530-90108RT South25SCM112384116694583428-75309Minto North25SCM11338528269434380-90207RT South25SCM1143843436944130200-74363Area 11825SCM11538526169434170-90162RT South Table 3: Significant Interval TableHole IDFromToLength (m)Cu %Au g/tAg g/tCuEq %Zone25SCM052177.9204.826.82.581.5012.673.81%Minto NorthIncl.190.1204.814.74.192.5021.156.23%Minto North25SCM05769789.00.550.111.790.65%Area 118And*212.1241.829.70.7650.423.561.1%Area 11825SCM072167.0185.518.50.600.292.870.85%Area 11825SCM07314.032.018.00.360.030.670.39%RT South25SCM083No Significant InterceptRT South25SCM08445.2856.4811.21.200.444.221.57%RT South25SCM085Assays pendingArea 11825SCM086175.9179.03.10.670.051.910.72%Minto North25SCM087Assays pendingArea 11825SCM08828.534.56.00.440.051.090.48%RT South25SCM08935.447.311.91.030.314.551.29%RT Southand98.9104.65.72.750.7710.863.42%RT South25SCM09024.038.014.00.470.321.410.72%Area 118and79.293.614.42.681.8111.914.13%Area 11825SCM09150.869.018.20.410.112.220.51%Ridgetop25SCM092461.6467.96.30.900.212.081.07%Minto East25SCM093No Significant InterceptMinto North25SCM094Assays pendingArea 11825SCM09562.078.016.00.720.263.470.94%RT South25SCM096Assays pendingMinto North25SCM097Assays pendingRT South25SCM09863.970.56.65.183.8527.028.28%Area 118and243.1253.110.00.480.382.690.79%Area 11825SCM09998.5108.510.00.810.052.490.87%RT South25SCM100No Significant InterceptArea 11825SCM10148.556.27.70.230.110.780.32%RT South25SCM10210.015.05.01.060.312.761.32%RT South25SCM103A211.5216.14.60.710.093.250.81%Minto East25SCM10415.422.77.30.980.313.241.24%RT South25SCM105No Significant InterceptRT South25SCM106No Significant InterceptMinto North25SCM10710.916.85.90.790.272.421.01%RT South25SCM108No Significant InterceptRT South25SCM10957.067.510.50.380.121.780.48%RT South25SCM110322.0333.011.00.370.092.160.45%Minto East25SCM11141.948.66.70.360.010.730.37%RT South25SCM112234.9244.09.11.430.568.451.92%Minto NorthIncl.237.5238.61.18.022.6349.5910.41%Minto North25SCM113No Significant InterceptRT South25SCM114220.0227.57.50.800.312.051.05%Area 11825SCM11529.448.118.70.300.080.780.37%RT SouthAt the Minto North and Minto East zones, the flat laying to shallowly dipping nature of the mineralized zones suggest that true widths are typically >90% of the reported drill intersection length.

Recoveries as estimated from historical mineral processing results. QAQC Procedures and Data ValidationThe Company is drilling NQ sized core. Following data collection, core is cut along the long axis, with half of the core going to the lab for chemical analysis and the remaining half kept in sequence as record. The half core samples are packaged with the corresponding sample tag id and sealed. All sampling is conducted by Selkirk Copper Mines Inc. and subject to Company standard internal quality control and quality assurance (QAQC) programs which include the insertion of certified reference material, coarse blank materials, and field duplicate analysis, on top of the standard laboratory QAQC procedures to monitor contamination during preparation and analytical accuracy and precision. QAQC insertion rates approximate 15% of all samples at set intervals. For the 2025 program all samples were sent to ALS Laboratory's prep laboratory in Whitehorse, YK, then shipped to ALS Vancouver for gold fire assay and four-acid multi-element analysis. All samples are prepared by crushing rock to 70% passing 2mm screen, then splitting a 250g sub-sample using a riffle splitter before being pulverized 85% passing 75 microns. Gold is analyzed by 30 g Fire Assay (Au-AA23) with atomic absorption (AAS) analysis followed by gravimetric finish for overlimit results. Copper is analyzed by four-acid digest (ME-ICP61) with inductivity coupled plasma - atomic emission spectroscopy (ICP-AES) finish. If Cu overlimit results are triggered a second four-acid digest for high grade copper (Cu-OG62) is conducted. For any samples where oxide copper minerals are identified, a sulphuric acid leach (Cu-AA05) analysis with AAS finish is performed. ALS Vancouver holds an ISO/IEC 17025 standard accreditation.QAQC results are reviewed open receipt of results. Overall QAQC results show strong analytical performance across Cu, Au, and Ag datasets. All control standards are within acceptable tolerance, with no significant outliers or systematic bias observed. Primary intervals are reported as drill core length, with true widths estimated to be approximately 90% of core lengths, based on the sub-horizontal to shallow dipping nature of the modelled mineralized zones.

Selkirk Copper Completes Phase 1 Drill Program and Assumes Site Responsibility for Minto Copper-Gold-Silver MineApril 15, 2026 7:00 AM
NewsfileHighlightsSelkirk Copper has successfully completed its Phase 1 drill program, comprising 52,288 m of drilling in 175 holes. This represents one of the largest drilling programs completed in Yukon in the last ten years. The drill program, employing four (4) diamond drills, was completed safely with zero medical aid or lost time injuries. The program was completed on-schedule with high productivity averaging 94 metres per day per drill, and relatively low cost-per-metre. Resource expansion and exploration drilling had a high rate of success with 87% of holes intersecting one or more mineralized lenses of significant grade and thickness. Assay results have been released for 48% of the Phase 1 drill program, with outstanding assays expected to be released over the next two months. As of April 1, 2026, Selkirk Copper assumed responsibility for site operations, including care and maintenance activities. Selkirk Copper expects to undertake several project readiness activities ahead of a potential restart decision in mid-2027.Leadership Team UpdateWe are pleased to announce the appointment of Shiro Rae as Director, Business Planning and Site Operations who will direct and support all aspects of Selkirk Copper's site-based work programs including safety, camp operations, environment, care and maintenance, and exploration and resource drilling program working closely with Selkirk Copper's leadership team.Vancouver, British Columbia and Pelly Crossing, Yukon--(Newsfile Corp. - April 15, 2026) - Selkirk Copper Mines Inc. (TSXV: SCMI) (FSE: IO20) (OTCQB: SKRKF) ("Selkirk Copper" or the "Company") is pleased to announce completion of the Phase 1 drill program, and assumption of responsibility for site operations at the Minto Mine in Yukon, Canada. M. Colin Joudrie, President & CEO, commented: "With the successful completion of the Phase 1 drill program, I want to extend sincere thanks to the Selkirk Copper exploration team, our exploration contractors including Omineca Drilling, and the Selkirk First Nation for all of their hard work. With drilling now completed we expect a steady flow of assay results from the Phase 1 drill program, that we will continue to release through the end of May, which will inform an updated Mineral Resource Estimate and a Preliminary Economic Assessment that is on schedule for completion by mid-2026."We are also pleased that Selkirk Copper has taken over responsibility for operations of the Minto Mine site. This marks an important milestone as the site transitions away from a focus on care and maintenance, towards resource expansion, engineering and trade-off studies, and site-wide technical data collection, to inform a potential restart decision in mid-2027."I would like to welcome Shiro Rae to the team. Shiro's leadership and experience managing large scale project activities with complex camp and site operations in the NW of British Columbia along with his experience working directly with First Nation Communities, First Nation Development Corporations, and local suppliers and service providers, will greatly assist Selkirk Copper's restart planning activities."2025-2026 Phase 1 Drill ProgramThe Phase 1 drill program was conducted between August 2025 and March 2026 with four diamond drill rigs. Drilling was continuous throughout this time, except for a six-week break during December to January when winter temperatures on site reached as low as -55°C. Drilling was completed safely, with no medical aid or lost-time injuries, and minimal downtime. Drilling productivity was very high, including individual drills producing more than 200 metres per day in some instances, with an average of 94 metres per day per drill throughout the entire program (Figure 1). High productivity and relatively low cost-per-metre enabled surpassing of the originally planned 50,000 m program, resulting in completion of 52,288 metres representing 105% of the initial plan. On-site activities related to the Phase 1 drill program, including core logging, cutting, and sampling, are expected to be completed before mid-April. Outstanding assay results are expected to be received and released over the next two months, with approximately 48% of the drill results reported to-date. Geological modelling is underway to incorporate drill results into the updated mineral resource estimate (MRE) which is expected to be completed in June 2026.Results from the Phase 1 drill program and updated MRE will be used to support a Preliminary Economic Assessment (PEA), which is scheduled for completion in mid-2026. Technical studies, engineering designs, and mine plan scheduling to support the PEA are advancing as planned.Figure 1: Summary of metres drilled by drill rig, highlighting the measured ramp up starting in August to our full production in October.

https://images.newsfilecorp.com/files/11605/292654_figure%202.jpgPhase 1 Drill Program HighlightsThe Phase 1 Drill Program targeted resource expansion in six locations within the Minto mine area. In each location, resource expansion drilling stepped-out along sub-horizontal mineralized lenses at varying distances ranging from 40 to 80 metres per hole. Drill plans and priorities evolved iteratively, with early results guiding subsequent work. Significant extensions to mineralized lenses were identified in several areas, most notably Minto North, Ridgetop and Minto East. Success for resource expansion drill holes was evaluated based upon grade and thickness of mineralized lenses that were intersected within each drill hole. Some holes intersected multiple stacked lenses of mineralization, producing several significant intercepts for each drill hole. Copper grades from assays released in the first half of the Phase 1 drill program correlate well with visual logged estimates of bornite and chalcopyrite mineralization. Based upon available assays and visual logged estimates, approximately 87% of Phase 1 drill holes are considered to have intersected notable mineralization, although assay results for the second half of the drill program are still pending. Highlights from resource expansion drilling (Figure 3) include expansion at the Minto North west zone which is estimated to have increased at least two times from the 2025 MRE modelled volume. Drilling in the Minto North west zone returned very high grades in multiple drill holes including 25SCM043 (see previous release on February 19, 2025). This drill hole intersected 3.52% Cu, 3.51 g/t Au and 17.04 g/t Ag (6.3% CuEq) over 16.7 m, within a broader zone of 2.09% Cu, 1.84 g/t Au and 9.48 g/t Ag (2.9% CuEq) over 32.9 m. This result is within the top 99th percentile of grade and thickness for all drilling within the Minto database, which spans six decades and includes more than 1,400 drill holes and more than 4,300 significant intercepts. Additional assay results are pending from the Phase 1 drill program at Minto North, and the mineralized lens remains open to the south and will be a priority for further follow-up during the Phase 2 drill program.Figure 3: Global long section looking East, highlighting holes 25SCM043, 26SCM128, 26SCM126, 26SCM157 and 25SCM057 as discussed in text.To view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/11605/292654_figure%203.jpgThe Phase 1 Drill Program also included more aggressive exploration drilling, including larger step-outs, targeting of untested geophysical anomalies, and targeting of new mineralized lenses at depth beneath known resource areas. Geophysical targeting was guided from a compilation of known and available property-wide geophysical data sets linked to the observed geology and associated mineralogy. The team continues to develop a deeper understanding of the lithological and mineralogical characteristics of the mineralized zones and how they relate to geophysical anomaly intensities most closely associated with copper-gold mineralization including moderate-to-high chargeability, low resistivity, and high magnetic intensity. Exploration targeting has also been guided by deposit model criteria that were developed during the Phase 1 drill program, including understanding of structural controls, mineralized trends, and sulphide zonation. Highlights from exploration drilling include discovery of a new mineralized lens in Area 118 approximately 120 metres below the previously known resource. Results from this new lens include drill hole 25SCM057 which intersected 0.76% Cu, 0.42 g/t Au, and 3.56 g/t Ag (1.15 % CuEq) over 29.7 m (see previous release on March 25, 2026). Subsequent exploration drilling has delineated this new lens over an area approximately 500 x 400 metres. Assay results are still pending for several drill holes in this area, including 26SCM157 which intersected a 14-metre interval containing disseminated bornite and chalcopyrite (Figure 4). This newly discovered lens remains open in several directions and will be a priority for further follow-up drilling during the Phase 2 drill program.Additional highlights from exploration drilling in the Phase 1 drill program include several of the deepest intercepts of mineralization that have been drilled at Minto over sixty years of previous work. Assay results are still pending for several deep drill holes, including 26SCM126 beneath Minto Main which intersected sparsely disseminated bornite-chalcopyrite mineralization over 60 m from 720-787 metres downhole; and 26SCM128 in Minto East which intersected a 10-metre interval containing bornite and chalcopyrite at a depth of 650 metres downhole. Both of these drill intercepts are indicative that mineralization remains open at depth beneath the limits of previous drilling and in several directions. Additional exploration drilling into these areas is proposed once access to the underground has been re-established.Figure 4: Detail photograph of semi-massive bornite and chalcopyrite mineralization in recently discovered mineralized lens located 120m below the Area 118 resource zone. This photograph is from within a 14-metre interval with visible sulphides. Assay results for this hole are pending.To view an enhanced version of this graphic, please visit:

Mr. Rae holds a B.Sc. (Honours) in Geology and a B.A. in Economics from the University of British Columbia.QAQC Procedures and Data ValidationThe Company is drilling NQ sized core. Following data collection, core is cut along the long axis, with half of the core going to the lab for chemical analysis and the remaining half kept in sequence as record. The half core samples are packaged with the corresponding sample tag id and sealed. All sampling is conducted by Selkirk Copper Mines Inc. and subject to Company standard internal quality control and quality assurance (QAQC) programs which include the insertion of certified reference material, coarse blank materials, and field duplicate analysis, on top of the standard laboratory QAQC procedures to monitor contamination during preparation and analytical accuracy and precision. QAQC insertion rates approximate 15% of all samples at set intervals. For the 2025 program all samples were sent to ALS Laboratory's prep laboratory in Whitehorse, YK, then shipped to ALS Vancouver for gold fire assay and four-acid multi-element analysis. All samples are prepared by crushing rock to 70% passing 2mm screen, then splitting a 250g sub-sample using a riffle splitter before being pulverized 85% passing 75 microns. Gold is analyzed by 30 g Fire Assay (Au-AA23) with atomic absorption (AAS) analysis followed by gravimetric finish for overlimit results. Copper is analyzed by four-acid digest (ME-ICP61) with inductivity coupled plasma – atomic emission spectroscopy (ICP-AES) finish. If Cu overlimit results are triggered a second four-acid digest for high grade copper (Cu-OG62) is conducted. For any samples where oxide copper minerals are identified, a sulphuric acid leach (Cu-AA05) analysis with AAS finish is performed. ALS Vancouver holds an ISO/IEC 17025 standard accreditation.QAQC results are reviewed open receipt of results. Overall QAQC results show strong analytical performance across Cu, Au, and Ag datasets. All control standards are within acceptable tolerance, with no significant outliers or systematic bias observed. Primary intervals are reported as drill core length, with true widths estimated to be approximately 90% of core lengths, based on the sub-horizontal to shallow-dipping nature of the modelled mineralized zones.
