/NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR DISSEMINATION IN OR INTO THE UNITED STATES/

 Silver Mountain Resources Inc. ("Silver Mountain" or the "Company") (TSX: AGMR) (OTCQB: AGMRF) (BVL: AGMR) is pleased to announce the commencement of the first phase of a 14,000-meter diamond drilling campaign at its Caudalosa Mine, alongside a significant operational advancement at the Reliquias Mine as the Company accelerates toward its fully funded Q3 2026 production restart.

Caudalosa Drill Program

The Company has commenced the first phase of a 14,000-metre drill program at Caudalosa, targeting resource expansion, grade enhancement, and the delineation of additional mineable zones. Initial drill results are expected in April 2026.

This program marks the beginning of a disciplined growth strategy designed to unlock Caudalosa's full geological potential, with a focus on converting mineralized targets into near-term production opportunities and long-term value for shareholders. With silver fundamentals strengthening and capital markets reopening to high-quality silver developers, Silver Mountain is advancing exploration at a critical moment in the cycle.

Reliquias Mine Restart

Development at the Reliquias Mine remains on track and on budget for a planned restart of operations in Q3 2026. Multiple workstreams are advancing in parallel in connection with the restart.

Key operational highlights include:

  • Raise boring operations have commenced, accelerating underground infrastructure readiness.

  • Approximately 5,000 tonnes of mineral have been stockpiled to date which will be supplemented by additional development ore to provide plant feed to the start of operations.

  • Installation of key new equipment is already complete or advancing according to schedule. Installation of refurbished plant components will begin by the end of March and other plant equipment is completing maintenance as per schedule.

  • Project expenditure tracking according to plan.

The restart of Reliquias is expected to materially reposition Silver Mountain as a producing silver company, with cash flow potential and operational leverage to silver prices.

Strategic Transition: From Restart to Expansion

With its recent TSX graduation completed, a strong treasury position, and operational execution advancing on schedule, Silver Mountain is entering a new phase defined by:

  • Production restart at Reliquias
  • Targeted resource growth and production pipeline expansion at Caudalosa
  • A strategy to build a multi-asset silver platform in Peru

The Company anticipates that 2026 could be a transformational year, with exploration catalysts in the near-term exploration catalysts at Caudalosa and medium-term production restart visibility at Reliaqias.

Alvaro Espinoza, Chief Executive Officer of Silver Mountain, commented: "We are executing our strategy decisively. Reliquias is advancing on schedule with infrastructure development underway, plant installation about to begin, and mineral already stockpiled for processing. At the same time, we have commenced a 14,000-meter drill campaign at Caudalosa targeting resource expansion. With initial results At Caudalosa expected in April 2026 and a Q3 2026 restart at Reliquias firmly in sight, we are positioning Silver Mountain for a re-rating as we transition into a growth-oriented silver producer."
