GR Silver Mining (GRSL.V), which rose 10% on Thursday, said overnight that it received official notification from Mexico's Secretaria de Medio Ambiente y Recursos Naturales (SEMARNAT) that production of a new MIA, an Environmental Impact Authorization, for the former Plomosas Mine will not be required.
This decision is based on the existence of existing infrastructure, the company's plans to rehabilitate and modernize the existing infrastructure, no change in land use, and no expected increase in environmental impact or risk, the company said. The decision also allows the company to proceed with its plans for a Bulk Sampling Test Mining (BSTM) program without having to produce a new MIA.
"The principal secondary road from Durango to the project is currently being upgraded to facilitate faster supply and egress," said the company in a statement. "The company is targeting completion of its drill program in the second half of 2026, to be followed by an updated Mineral Resource Estimate and a Preliminary Economic Assessment integrating the Plomosas Mine Area and the San Marcial Area, with final timing dependent upon ongoing access."
Also, Eric Zaunscherb has resigned from his position as Executive Chair of the company's board to focus on the Interim President and Interim Chief Executive roles, it said. Director Larry Taddei has been appointed Lead Independent Director, the company added.
