Minera Alamos Inc. (TSX-V: MAI) (OTCQX: MAIFD) is pleased to report preliminary operational results for the three months ended December 31, 2025  from the Pan Operating Complex. All amounts are in United States dollars, unless otherwise stated.

Minera Alamos CEO, Darren Koningen, commented, “Having closed the acquisition of the Pan Operating Complex on October 1, 2025, Q4 was our inaugural quarter as a gold producer in Nevada, USA. Our strong operating team at Pan showed a seamless transition under Minera Alamos ownership, resulting in gold production of 9,165 ounces at AISC of US$1,604 per ounce. Combined with continued operating cost discipline and strong gold prices in Q4, we ended the year with a record cash balance of US$34 million.”

“With the Pan mine as our cash flow engine, Minera Alamos is well positioned to execute on our strategy to become a leading, Americas-focused intermediate gold producer by growing production and developing our pipeline of high-quality, low-capital projects while expanding gold resources across our portfolio.”

The Pan mine produced 9,165 ounces of gold and sold 8,492 ounces in Q4 2025, with the remaining 673 produced ounces sold at the beginning of 2026. This exceeded the Company’s previously forecasted range of 8,500–9,000 ounces for Q4 2025, as announced in the News Release dated October 28, 2025. Full-year 2025 gold production of 35,303 ounces achieved annual guidance of 30,000–40,000 ounces. Preliminary cash costs at Pan were US$1,549 per ounce for Q4 2025 and preliminary AISC were US$1,604 per ounce. Final reconciled cash costs and AISC will be reported in the coming months in the Company’s full quarterly report.

The Company’s unrestricted cash balance (unaudited) increased to US$34 million as of December 31, 2025. Minera Alamos anticipates announcing 2026 guidance for Pan in the coming weeks.

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 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, available on SEDAR+.

Cash costs. The Company uses 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 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. 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. Cash costs include production costs, refinery and transportation costs, royalties and production taxes. 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 is a performance measure that reflects the total expenditures that are required to produce an ounce of gold from current operations. While there is no standardized meaning of the measure across the industry, the Company’s definition is derived from the definition as set out by the World Gold Council in its guidance dated June 27, 2013 and November 16, 2018, respectively. The World Gold Council is a non-regulatory, non-profit organization established in 1987 whose members include global senior mining companies. The Company believes that this measure is useful to external users in assessing operating performance and the ability to generate free cash flow from operations. The Company defines AISC as the sum of total cash costs, corporate general and administrative expenses (excluding one-time charges), reclamation accretion related to current operations and amortization of asset retirement obligations (“ARO”), sustaining capital (capital required to maintain current operations at existing production levels), lease repayments, and exploration expenditures designed to increase resource confidence at producing mines. AISC excludes capital expenditures for significant improvements at existing operations deemed to be expansionary in nature, exploration and evaluation related to resource growth, rehabilitation accretion not related to current operations, financing costs, debt repayments, and taxes. Total AISC is divided by gold ounces sold to arrive at a per ounce figure.
