A 78-square-kilometre group of 100%-owned concessions on the southwestern edge of the Sierra Madre Occidental in the Rosario Mining District. The unified project includes San Marcial, the former Plomosas underground mine and San Juan-La Colorada. The March 2023 resource covers all three areas and remains at exploration stage because no preliminary economic assessment, feasibility study or reserve has been completed. GR Silver is conducting step-out drilling for a new resource estimate while evaluating bulk-sampling test mining and a pilot plant at the historic mine infrastructure. Those activities are test work and do not constitute commercial construction or current production.
