(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.The 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.GR 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.Recent 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 has a...","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}
