Minera Alamos Announces Positive Pre-Feasibility Study for the Copperstone Gold Project in ArizonaMay 27, 2026 5:00 PM
NewsfileBoard of Directors Approves Fast-Track ConstructionToronto, Ontario--(Newsfile Corp. - May 27, 2026) - Minera Alamos Inc. (TSXV: MAI) (OTCQX: MAIFF) ("Minera Alamos" or the "Company") is pleased to announce the results of a pre-feasibility study (the "PFS") on its 100%-owned, past-producing Copperstone project ("Copperstone" or the "Project") located in La Paz County, Arizona, USA. A technical report for the Copperstone PFS is being prepared in accordance with National Instrument 43-101 ("NI 43-101") and will be filed under the Company's profile on SEDAR+ and on the Company's website within 45 days of this news release.All dollar amounts in this news release are expressed in U.S. dollars, unless otherwise noted. Metric tonnes are referred to as "t", imperial short tons as "st", grams as "g", gold as "Au", troy ounces as "oz", thousands of troy ounces as "koz", and millions as "M".Copperstone Pre-Feasibility HighlightsStrong project economics:At base case gold price of $3,500/oz, after-tax net present value 5% ("NPV5%") of $374 M, internal rate of return ("IRR") of 108%, payback period of 1.2 years, and net cashflow of $512 M.At spot gold price of $4,500/oz, after-tax NPV5% of $537 M, IRR of 154%, payback period of 0.8 years, and net cashflow of $725 M.Resilient, low-cost mine plan: PFS life-of-mine ("LOM") plan shows an initial 6.3-year mine life producing a total of 291 koz gold with average annual production of 46 koz at total cash costs1 of $1,070/oz gold and all-in sustaining costs1 ("AISC") of $1,314/oz gold. Initial production anticipated in mid-2027, more than doubling the Company's projected annual gold production: Based on the PFS results and current estimates, project construction is expected to take approximately one year, with initial gold production anticipated by mid-2027. Given Copperstone's average annual production of 46 koz gold per year, the project has the potential to more than double the Company's consolidated annual gold production, as compared with the 2026 guidance for 32 koz – 38 koz from the Pan mine in Nevada.Low capital intensity: Total initial capital cost ("capex") of $58 M and sustaining capex of $77 M over the LOM. Based on initial capex, the Project has a NPV-to-capex ratio of 6.4x using base case gold price of $3,500/oz, and NPV-to-capex ratio of 9.2x using spot gold price of $4,500/oz. The initial capex of $58 M to be comfortably financed by the Company's existing cash balance (Q1 2026, $46 M), excess capacity under the recently closed $75 M revolving credit facility, and ongoing cash flow from the Pan mine in Nevada. Increased Resources and maiden Reserves: Increased Measured & Indicated ("M&I") Resources to 4,054 kt grading 4.83 grams per tonne gold ("g/t") and containing 630 koz gold, representing a 110% increase in contained gold ounces compared to the previous mineral resource estimate. Maiden Proven & Probable Reserves are 1,934 kt grading 4.87 g/t and containing 303 koz gold.Fully permitted for construction: Copperstone is a previously mined property with active mining and environmental permits.Significant exploration potential to increase mine life: Approximately half of the Measured & Indicated Resources were not converted to Reserves. Further drilling, mine development, and mine optimization could increase the likelihood of future conversion to Reserves. Additionally, the down-plunge extension potential of the underground mineralization will be further evaluated from underground drill stations after production starts, where much of the known mineralized zones are open at depth.Additional Open Pit Potential: The Copperstone project has an extensive history of both open pit and underground mining. For the purposes of the updated Copperstone PFS, only underground accessible Resources were considered. A portion of these Resources exist in near-surface areas in proximity to the historic open pit excavations ("Open Pit Potential"), and the Company believes there is potential for gold mineralization to be extracted via open pit mining methods. 1 Total cash costs and AISC are non-IFRS measures. For more details refer to the "Non-IFRS Measures" section of this release.Darren Koningen, President & COO, commented, "The Copperstone PFS results show a high-return, low capital underground gold mining project with first gold production anticipated in mid-2027 and which will more than double our Company's annual gold production once ramped up. Our Board has made a formal investment decision for construction of the Copperstone project, with full-scale engineering, procurement and construction activities commencing in June, and mobilizing the underground mining contractor in the near-term. The increase in initial capital cost versus the 2025 PEA allows for an expanded process plant capable of increasing throughput from 600 tons per day to 1,000 tons per day. In addition, a planned 3-month ore stockpile ahead of mill startup helps to de-bottleneck the commissioning and ramp-up of the project."The PFS represents an excellent starting point for the project while the Company continues to evaluate opportunities for resource expansion underground and potentially including a new open pit."Figure 1 – Copperstone project site overviewTo view an enhanced version of this graphic, please visit:

The site access road is located about 9 miles north of Quartzsite along US Highway 95. The access road is a well-maintained gravel road, the Cyprus Mine Road, that travels west for 5.5 miles to the project site.The Project is situated on the flat, sandy desert terrain of the La Posa Plain, at the northeastern end of the Dome Rock Mountains, and is surrounded by a natural desert scrub environment. Major supply centres and ample skilled and unskilled labour are available locally, in Phoenix and in Yuma. Access to the Sante Fe rail line is available nearby, and international air service and railway access are both available in Phoenix.The project benefits from the presence of significant existing operations infrastructure including power distribution, buildings, roads, tailings storage facility, water rights, and part of the process facility.Updated Mineral Resource EstimateThe Copperstone mineral resource estimate ("MRE") is presented in Table 3 below. The MRE is reported at an underground mining cut-off of 0.064 oz/ton gold (2.2 g/t Au). Resources were estimated using an inverse-distance-squared methodology within an overall indicator-kriged model boundary to approximately delineate the boundary between mineralized and unmineralized material. After the block grade estimations were complete, Deswik Stope Optimizer was used as a guide to generate mineralized zones based on $3,000/oz gold price and minimum mining widths and economic parameters consistent with the type of mineral system present at Copperstone. This Resource is considered by the author to have reasonable prospects for eventual economic extraction.Table 3 – Copperstone Mineral Resource estimate, effective December 1, 2025ClassificationTonnes

The cut-off is based on the following assumptions: a gold price of $3,000/oz; assumed mining cost of $102.87/ton ($113.16/tonne), process costs of $42.64/ton ($46.90/tonne), general and administrative and property/severance tax costs of $16.39/ton ($18.03/tonne), refining and shipping costs of $12.00/oz, a metallurgical recovery for gold of 95%, and a 4.5% gross royalty.Resources are reported using at a minimum overall gold cut-off grade of 0.064 oz/ton Au (2.2 g/t Au). Internal dilution is incorporated into the MSO shape volumes as part of the estimated quantities and grades.Previously mined areas were modelled based on all available records and were excluded from reporting of this mineral resource.Mineral Resources are reported inclusive of Mineral Reserves. Mineral Reserves are estimated from Measured and Indicated Mineral Resources. Inferred Mineral Resources are not included in the Mineral Reserves.Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability and may be materially affected by modifying factors including but not restricted to mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors. There has been insufficient exploration to define the Inferred Resources tabulated above as an Indicated or Measured Mineral Resource, however, it is reasonably expected that the majority of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. There is no certainty that any part of the Mineral Resources estimated will be converted into Mineral Reserves.Numbers in the table have been rounded to reflect the accuracy of the estimate and may not sum due to rounding.Scott Zelligan, P. Geo. is responsible for reviewing and approving the Copperstone mine underground Mineral Resource Estimate. Mr. Zelligan is a Qualified Person ("QP") as set out in NI 43-101Mineral Reserve EstimateThe mineral reserves for the Copperstone underground gold project are estimated in accordance with the CIM Definition Standards. Measured mineral Resources are converted to Proven Reserves, while Indicated mineral Resources are converted to Probable Reserves. Inferred Resources are excluded from the reserve calculation and are treated as waste.Table 4 – Copperstone Mineral Reserve estimate, effective December 1, 2025ClassificationTonnes

Costs were based on the operating costs ranges as outlined in Table 1.Mineral Reserves were estimated using a gold price of $3,000/oz, metallurgical recovery of 95%, and a cut-off grade of 0.0642 oz/ton Au (2.2 g/t Au). Mining recovery of 95% and external dilution of 10% at zero grade applied. Inferred mineral resources are not mineral reserves and do not have demonstrated economic viability. Inferred resources are excluded from this reserve estimate and treated as waste. Numbers are rounded to the nearest ton or ounce; rounding may cause minor discrepancies in totals. Reserves are contained within the measured and indicated mineral resources. No additional material has been added. Peter Szkilnyk, P.Eng., is responsible for reviewing and approving the Copperstone mine underground Mineral Reserve Estimate. Mr. Szkilnyk is a Qualified Person ("QP") as set out in the NI 43-101.Mine Design and Production ProfileThe proposed mining method for the Copperstone Project is an overhand mechanized cut-and-fill approach utilizing cemented rock fill. This method was selected for its flexibility in efficiently extracting ore from zones with low vein dip angles. It also helps minimize dilution through precise geological control and disciplined mining practices. Underground mining methods were evaluated with the objectives of minimizing dilution, capital and operating costs, and maximizing resource recovery while sustaining the planned mill throughput. The Copperstone mineralization is relatively shallow, with an average dip of approximately 38 degrees. Although certain zones exceed a 45-degree dip and can be mined using gravity-assisted methods, most of the deposit is too flat to be efficiently mined using long hole stoping.Figure 2 – Copperstone PFS LOM Plan Tonnes and GradeTo view an enhanced version of this graphic, please visit:

https://images.newsfilecorp.com/files/4183/299120_2dc5bec7e433daaf_006full.jpgProcess Plant DesignThe proposed flowsheet will incorporate crushing, grinding, flotation, and cyanide leaching circuits to produce a gold concentrate and gold-loaded carbon products. The saleable gold concentrate will be shipped to a port on the west coast for shipping to a refinery, while the loaded carbon will be transported to the Company's Pan mine processing facility for further processing (refining). The "hybrid" process was selected to provide maximum flexibility to maintain overall high gold recoveries regardless of fluctuations in the mineralization recovered from the mine.The process plant is designed wherever possible to maximize the use of existing plant infrastructure and equipment, including the primary and secondary crushers, screens, ore bin conveyors, laboratory, and electrical distribution systems. The plant has been designed with an anticipated availability of 92% and projected overall gold recovery of approximately 96%. Initial effective processing capacity is expected to be 544 tpd (600 stpd) during the first year of operations, increasing to 907 tpd (1,000 stpd) from the second year onward.Tailings Storage FacilityPart of the existing infrastructure at the Copperstone project is a previously constructed and permitted tailings storage facility ("TSF"). Based on current production rate assumptions used in the PFS, the existing TSF is estimated to provide approximately 1.5 years of tailings storage capacity. The Company has planned a TSF expansion to accommodate production beginning late in year 1 of operations, with an additional lift planned later in the mine life. These planned expansions are already considered in the TSF permits for the project.Operating Cost EstimatesThe operating costs include the ongoing cost of operations related to mining, processing, tailings disposal, and general administration activities. The operating costs were determined based on the Company's in-house database of projects and studies, budgetary mining contractor quotes and data/estimates provided by GR Engineering Services Inc. ("GRES"). LOM average costs are summarized in the table below. Table 5 – Operating Cost SummaryOperating Costs $/oz Au$/tonne oreTotal Mining$654$98.39Total Processing$158$23.79Total Site G&A$53$8.06Transportation and Refining$13$2.01Cash Operating Costs$878$132.24Royalties$158$23.71Production Taxes$34$5.19Total Cash Costs$1,070$161.15Corporate G&A$10$1.55Reclamation cost - prorated$17$2.59Exploration costs - sustaining$28$4.16Capital costs - sustaining$189$28.43AISC$1,314$197.88 Capital Cost EstimatesThe basis of the PFS capital cost estimate included capacity sufficient for an expansion in processing throughput up to 1,000 stpd after the initial production startup.Cost estimates are based on the Company's in-house database of operations, projects, and prior studies, as well as budgetary quotations from mining contractor and mine equipment suppliers. GRES prepared the capital estimates for the re-build of the process plant. Apart from the primary grinding mill, process plant estimates are based on new equipment pricing. However, the Company intends to utilize a combination of new and refurbished equipment to optimize capital costs while minimizing the risk of cost overruns.Pre-production capital includes mine refurbishment and underground development activities, including the establishment of a planned three-month ore stockpile to support smooth commissioning and ramp-up of the new milling complex. Two planned phases of expansions of the tailings facility have been accounted for in the sustaining capital period.A summary of the initial and sustaining capital costs over the LOM are shown below.

The construction period is expected to last approximately one year, with initial production anticipated by mid-2027.Pre-construction activities commenced earlier this year, with select major process plant components having been delivered to the project site in recent weeks. Mobilization of an underground mining contractor is expected to occur in the coming 2-3 months. Benefitting from over 4 km of existing underground development, the overall goals for underground work this year will be to rehabilitate areas where required, access new stoping areas, and establish all underground infrastructure required for mining operations.RecommendationsThe Copperstone project has an extensive history of both open pit and underground mining. For the purposes of the Copperstone PFS, only underground accessible Resources were considered. A portion of these Resources exist in near-surface areas in proximity to the historic open pit excavations ("Open Pit Potential"). The Company believes there is potential for gold mineralization to be extracted via open pit mining methods which would allow for the consideration of reduced cut-off grades. This opportunity will be more fully evaluated over the course of 2026 and 2027.Additional mine development optimization is ongoing to look at opportunities to delay some of the mine preproduction activities for completion after the start of production. In addition, studies continue to evaluate potential updates to mine stope sequencing and different cut-off grades to maximize gold production throughout the mine plan.Follow-up underground in-fill drilling is planned to commence once operations are underway to support mine planning and sequencing and will also target future Resource expansions.Non-IFRS Measures. This news release refers to certain financial measures, such as cash costs and all-in-sustaining costs, which are not measures recognized under IFRS and do not have a standardized meaning prescribed by IFRS. These measures may differ from those used by other companies and, accordingly, may not be comparable to such measures as reported by other companies. These measures have been derived from the Company's financial statements because the Company believes that they are of assistance in understanding the results of operations and its financial position. Certain additional disclosures for these specified financial measures have been incorporated by reference and can be found in the Company's MD&A, available on SEDAR+.Total cash costs. The Company uses total cash costs per gold ounce sold to monitor its operating performance internally. The most directly comparable measure prepared in accordance with IFRS is cost of sales. The Company believes this measure provides investors and analysts with useful information about its underlying total cash costs of operations. The Company also believes it is a relevant metric used to understand its operating profitability and ability to generate cash flow. Total cash costs are measures developed by metals companies in an effort to provide a comparable standard; however, there can be no assurance that the Company's reporting of these non-GAAP financial measures are similar to those reported by other mining companies. They are widely reported in the metals mining industry as a benchmark for performance, but do not have a standardized meaning and are disclosed in addition to IFRS measures. Total cash costs include production costs, refinery and transportation costs, royalties and production taxes. Total cash costs exclude non-cash depreciation and depletion and site share-based compensation. Production costs include mining, crushing, processing, and direct overhead at the operation sites.AISC. AISC more fully defines the total costs associated with producing precious metals. The AISC is calculated based on guidelines published by the World Gold Council (WGC), which were first issued in 2013. In light of new accounting standards and to support further consistency of application, the WGC published an updated Guidance Note in 2018. Other companies may calculate this measure differently because of differences in underlying principles and policies applied. Differences may also arise due to a different definition of sustaining versus growth capital. Note that in respect of AISC metrics within the technical reports, because such economics are disclosed at the project level, corporate general and administrative expenses were not included in the AISC calculations. AISC per ounce includes mining, processing, direct overhead, reclamation and sustaining capital.Qualified Persons and NI 43-101 Technical ReportThe scientific and technical information contained in this news release has been reviewed and approved by Darren Koningen, P.Eng., President and COO of the Company, who is a "Qualified Person" ("QP") as defined under National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").

https://images.newsfilecorp.com/files/4183/295363_4709b04a741908ee_008full.jpgNon-IFRS Measures. This news release refers to certain financial measures, such as all-in-sustaining costs, which are not measures recognized under IFRS and do not have a standardized meaning prescribed by IFRS. These measures may differ from those made by other companies and, accordingly, may not be comparable to such measures as reported by other companies. These measures have been derived from the Company's financial statements because the Company believes that they are of assistance in understanding the results of operations and its financial position. Certain additional disclosures for these specified financial measures have been incorporated by reference and can be found in the Company's MD&A for Q4 2025, available on SEDAR+.Adjusted Net IncomeTo view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/4183/295363_4709b04a741908ee_009full.jpgTotal cash costs. The Company uses total cash costs per gold ounce sold to monitor its operating performance internally. The most directly comparable measure prepared in accordance with IFRS is cost of sales. The Company believes this measure provides investors and analysts with useful information about its underlying total cash costs of operations. The Company also believes it is a relevant metric used to understand its operating profitability and ability to generate cash flow. Total cash costs are measures developed by metals companies in an effort to provide a comparable standard; however, there can be no assurance that the Company's reporting of these non-GAAP financial measures are similar to those reported by other mining companies. They are widely reported in the metals mining industry as a benchmark for performance, but do not have a standardized meaning and are disclosed in addition to IFRS measures. Total cash costs include production costs, refinery and transportation costs, royalties and production taxes. Total cash costs exclude non-cash depreciation and depletion and site share-based compensation. Production costs include mining, crushing, processing, and direct overhead at the operation sites.AISC. AISC more fully defines the total costs associated with producing precious metals. The AISC is calculated based on guidelines published by the World Gold Council (WGC), which were first issued in 2013. In light of new accounting standards and to support further consistency of application, the WGC published an updated Guidance Note in 2018. Other companies may calculate this measure differently because of differences in underlying principles and policies applied. Differences may also arise due to a different definition of sustaining versus growth capital. Note that in respect of AISC metrics within the technical reports, because such economics are disclosed at the project level, corporate general and administrative expenses were not included in the AISC calculations. AISC per ounce includes mining, processing, direct overhead, reclamation and sustaining capital.Qualified PersonThe scientific and technical information contained in this news release has been reviewed and approved by Mr. Darren Koningen, P.Eng., Minera Alamos' CEO, who is the Company's Qualified Person under National Instrument 43-101.About Minera AlamosMinera Alamos is a growing North American gold production and development company with projects in Nevada, Arizona, and Mexico.
