The Company runs mining operations in Colombia and Nicaragua and holds a pipeline of development and exploration assets, including the La Pepa project in Chile and an exploration project in Tolima, Colombia. Its shares trade on the Toronto Stock Exchange under MSA, the Colombian Stock Exchange under MINEROS, and the OTCQX Best Market under MNSAF.

Adoption of Formal Strategic Gold Reserve Policy Establishing Physical Gold Bullion as Core Treasury Asset

Mineros has approved a Strategic Gold Reserve Policy that formally designates physical gold bullion as a core asset within the Company's treasury. The Board and management cite persistent inflation, sustained central bank gold purchases, and continued pressure on the purchasing power of monetary assets as the basis for allocating a measured portion of treasury assets to physical gold.

As a gold producer, Mineros will retain a portion of its own output in bullion form rather than converting all production to cash.

Chief Executive Officer Daniel Henao said:

"We produce gold because we believe in gold. The Policy formalizes a natural extension of our business: retaining a measured portion of our output in its most elemental form. Gold is the asset we understand best and holding it in treasury aligns the Company with shareholders who own Mineros for exposure to gold."

The gold will be accounted for as inventory of precious metals at the lower of cost and net realisable value, under the accounting standard IAS 2. Gold linked derivative instruments not designated as hedging instruments will be measured at fair value through profit or loss under IFRS 9.

Investment Committee Governance Framework and Quantitative Risk Limits Supporting Disciplined Capital Stewardship

Mineros has created an Investment Committee responsible for overseeing custody arrangements and setting risk limits for the gold reserve. The bullion will be held with institutional custodians and managed as a distinct asset class within the Company's treasury portfolio.

Chief Financial Officer Natalia Correa said:

"The Policy is supported by disciplined governance. We have established an Investment Committee, quantitative risk limits, and transparent reporting, including a new subtotal within our statement of cash flows that isolates strategic gold purchases, so that investors can evaluate the treasury position alongside operating performance."

The Policy sets out custody, accounting, and risk oversight parameters ahead of implementation, with the Investment Committee holding ongoing responsibility for how the reserve is managed under those parameters.

New Financial Reporting Subtotal and Strategic Liquidity Position Measure Enhancing Investor Transparency

Beginning with the quarter ended June 30, 2026, Mineros will include a new subtotal in its statement of cash flows: "operating cash flows before strategic gold purchases." This separates cash generated from mining operations from cash used to purchase gold for the treasury.

The Company has also introduced "Strategic Liquidity Position," a supplementary measure combining cash and cash equivalents with the value of physical gold bullion held. Mineros has updated its Net Free Cash Flow calculation to reconcile from the new operating cash flow subtotal. These measures supplement, and do not substitute for, the Company's IFRS financial statements.

The new subtotal separates recurring operating cash generation from period specific gold purchases within the statement of cash flows, so the two can be assessed independently of one another.

Milestones and Next Steps

The Strategic Gold Reserve Policy takes effect immediately, with the first financial statements reflecting the new cash flow subtotal and Strategic Liquidity Position measure due for the quarter ended June 30, 2026. Those results will show the initial scale of the gold allocation and how the new reporting measures are applied in practice.
