Strategic Step Toward a Broader Capital Markets Platform

"This is an important step in positioning Silver X as a recognized silver growth story in the U.S. market," said Jose Garcia, President, Chief Executive Officer, and Director of Silver X Mining Corp. "We are building a scalable, district-scale platform in Peru with current production, near-term growth visibility, and significant exploration upside. Trading on OTCQX expands our reach to a broader U.S. investor audience, strengthens our access to capital markets, and supports the next phase of growth at our Nueva Recuperada Silver Project. With production at our Tangana Mining Unit, immediate development opportunities, and meaningful brownfield expansion potential across our district-scale land package, we believe Silver X is well positioned to build a premier silver company and deliver long-term value for shareholders."

Positioned for Near-Term Growth and Long-Term Scale

Silver X is actively advancing its Nueva Recuperada Silver District in central Peru, a 20,000+ hectare land package with multiple mining units and over 200 exploration targets. The Company is currently processing approximately 750 tonnes per day, with a clear path to increase throughput to 1,000 tonnes per day, supported by operational improvements and high-grade feed from satellite deposits.

Key growth drivers include:

• Tangana Mining Unit, the current production hub, with ongoing optimization and development

• Near-plant satellite deposits, including high-grade opportunities such as Blenda Rubia and Red Silver

• District-wide exploration upside, with over 200 targets across a consolidated land package

• Recently acquired Pampas Project, a high-grade gold-silver asset with potential to become a second production center

This integrated, multi-asset approach positions Silver X to evolve from a single-operation producer into a district-scale silver company with multiple production sources and processing hubs.

Building a Scalable Multi-Asset Platform

Silver X's strategy centers on consolidating and advancing the broader Huancavelica district into a scalable, long-life mining platform supported by existing infrastructure, near-plant development opportunities, and district-wide exploration potential. The Company is focused on increasing metal production through higher throughput and grade optimization, advancing satellite deposits to supplement plant feed, and unlocking additional value through district consolidation and exploration.

Enhanced Visibility in the U.S. Market

OTCQX is designed for established, investor-focused U.S. and international companies.
