(TSXV: GRSL) has delivered a breakthrough discovery at its San Marcial project in Sinaloa, Mexico, with drill hole SMS25-09 intersecting 75 meters at 293 g/t silver equivalent, including a bonanza-grade core of 6.4 meters at 1,915 g/t AgEq. The results extend high-grade mineralization 100 meters below the current resource area, confirming continuity of what appears to be a large, well-preserved epithermal silver system.\nThe discovery represents a significant geological milestone, with CEO Marcio Fonseca explaining that the company believes it is \"scratching the upper portion of the system\" with potential for 500+ meters of additional depth. The presence of boiling textures—a critical indicator in epithermal systems—provides confidence that high-grade mineralization continues at depth. Structural analysis reveals intersecting northwest-northeast fault systems creating 25-meter-wide mineralized shoots in porous volcanic rocks, with only 20% of the identified geophysical anomaly currently tested.\nGR Silver Mining is pursuing a dual development strategy that balances near-term production potential with long-term exploration upside. The company's permitted Plomosas underground mine, which operated from 1985 to 2000, offers existing infrastructure and regulatory approvals for potential pilot-scale production within 12 months. Meanwhile, San Marcial represents substantial blue-sky potential, with the epithermal system remaining open both down-dip and laterally.\nRecent financing of C$13.8 million provides 12-15 months of operational funding, with 40% allocated to bulk sampling and test mining at Plomosas and the remainder focused on resource expansion drilling at San Marcial. The company maintains three drill rigs on site and...","thumbnail_url":"https://img.transistorcdn.com/1wv-MFlQAgnm-ca64e5kK4984dZB0os8-HJdRVsI74M/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzEzNTcyLzE2MjM5/NTQyMDctYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
