GR Silver Mining: Plomosas & San Marcial | RCTV at The Mining Investment Event of the North

Why It Matters

Accelerated production and a high‑grade, thick ore body position GR Silver Mining for earlier cash flow and a valuation premium, while mitigating security risks in a volatile region.

Key Takeaways

• Pilot plant at Plomosas could shave production timeline by two years.
• San Marcial drilling shows record grades, 22‑meter average thickness.
• 20,000‑meter drill program underway; 4,000 oz/meter efficiency claimed per hole.
• Office moved to Durango to avoid cartel‑blocked access routes.
• Founder Marcio Fav’s legacy fuels team dedication and project drive.

Summary

GR Silver Mining used the Mining Investment Event to update investors on its two flagship assets in Sinaloa, Mexico – the historic Plomosas mine and the adjacent San Marcial discovery. The company announced plans for a pilot plant at Plomosas that, if approved, could compress the path to commercial production from five years to three or four, leveraging an existing mining permit that now excludes the need for additional environmental authorization. The San Marcial project is the firm’s growth engine, with a 20,000‑meter drilling campaign already 4,000 m into execution. Recent holes have returned record‑high grades and an average ore‑body thickness of 22 metres, delivering roughly 4,000 ounces of silver per metre drilled – double the industry average. This geometry promises efficient long‑hole, open‑stoping methods and a strong resource upgrade once the full program is completed. Management highlighted operational challenges, noting the relocation of the exploration office from Rosario to Durango to sidestep cartel‑controlled routes. They also paid tribute to founder Marcio Fav, whose vision continues to motivate the team, describing the workforce’s commitment as “doing it for Marcio.” If the pilot plant proceeds and the San Marcial resource expands as projected, GR Silver could achieve cash flow several years earlier than peers, supporting a higher valuation given its low discovery cost and superior ounces‑per‑metre metrics. The strategic shift to a safer logistics hub and the ongoing drill results provide tangible catalysts for investors.

Original Description

RCTV speaks with Eric Zaunscherb, Interim President & CEO of GR Silver Mining, on the company’s past-producing Plomosas Project in Mexico and the ongoing drilling at San Marcial, where GR Silver recently reported its best-ever drill results. The discussion covers the planned Plomosas pilot plant, how bulk sample testing could help shorten the path to production, and major 2026 catalysts including San Marcial expansion drilling, an updated MRE, and a future PEA. Eric also provides insights into GR Silver’s discovery efficiency, including its cost of discovery and ounces per metre drilled compared with peers. The interview concludes with a reflection on the legacy of founder Marcio Fonseca and the team’s commitment to carrying forward his vision for the company.
