In alignment with GR Silver Mining Ltd.'s growth strategy, GR Silver Mining Ltd. has nominated Daniel Schieber as vice-president of corporate development and corporate relations, to foster existing and new relationships with shareholders and implement corporate development marketing planning under the leadership of Marcio Fonseca.

Mr Schieber has 15-plus years of experience in the capital markets associated with successful mining ventures particularly in the precious metals sector. In 2009, he co-founded Euroscandic International Group where he raised upward of $350-million in mining financing for specific development projects in the mining sector. He has recently pivoted to Canadian-investment vehicle Dynamis Capital Corp., which focuses on long-term, recession-proof investments with emphasis on gold and silver. Mr. Schieber currently serves on the board of directors and is CEO of American Copper Development Corp.

Mr. Fonseca comments: "Daniel brings 20 years of experience in raising capital and has already played a pivotal role in the recent recapitalization of GR Silver Mining. His continued contributions will be instrumental as the company advances to the next stage of growth in Mexico, driven by an active drilling program and a series of strategic initiatives supporting the development of the Plomosas project."

Mr. Schieber comments: "GR Silver Mining has reached a pivotal turning point -- fully funded, debt-free and ready to seize the opportunities of a strengthening silver market. Together with GR Silver Mining's team, I am committed to transforming the company into a successful enterprise, driven by substantial resource growth and a bold vision for long-term value creation."

About the Plomosas project

The Plomosas project, including the recent high-grade silver discovery in the San Marcial SE area, is progressing in 2025 as an emerging high-grade silver district located in southwestern edge of the Sierra Madre occidental, Sinaloa, Mexico. The Plomosas project, covering 7,823 hectares, including the historical Plomosas underground mine. benefits from mine infrastructure, road access and existing permits associated with past-producing mining sites. The district contains intermediate to low-sulphidation epithermal silver and gold mineralization, hosted in hydrothermal breccias and veins. Recent success in exploration and drilling has delineated wide, high-grade, shallow hydrothermal breccias in the San Marcial area, including the SE area discovery, where stepout drilling is under way in 2025, aiming for continuous resource growth. At the historical Plomosas mine, where Grupo Mexico operated the underground mine from 1985 to 2000, exploration, underground sampling and metallurgical programs are being conducted to support future decisions regarding the implementation of a bulk sampling test mining program
