First Underground Equipment Arrives at Silverco Mining's Canadian Mine and Tailings Filtration Civil Works Contract Awarded

en.Wedoany.com Reported - On November 12, Canadian mining company Silverco Mining announced that the first newly purchased underground development drill rig for its La Negra silver mine in Querétaro State, Mexico, has arrived at the mine site and, after completing initial surface commissioning, has been transferred to underground commissioning. Meanwhile, the company has engaged M3 Engineering & Technology to manage construction of the tailings filtration project and has awarded the civil works contract, with site mobilization planned for the end of November. The two projects are key components of the mine's rehabilitation to restore the processing plant to its designed capacity of 2,500 tonnes per day, with completion targeted for the first half of 2027.

The underground equipment renewal program involves a total of 6 units, including 1 development drill rig, 4 underground load-haul-dump (LHD) machines, and 1 production drill rig. The remaining equipment will be delivered in batches from the fourth quarter of 2026 through the first quarter of 2027. Epiroc will also deploy training personnel and maintenance technicians, with maintenance staff planned to be stationed on site for 6 months to handle equipment commissioning and operations and maintenance training.

Detailed design of the thickening and filtration facilities is approximately 90% complete. The civil contractor is expected to mobilize at the end of November, and the thickener and filter press are scheduled to arrive in the first quarter of 2027. Once completed, the project will transition the mine from conventional tailings discharge to filtered tailings dry stacking, reducing the constraints that tailings water management places on processing throughput. The company plans to complete construction and commissioning in the first half of 2027, restoring the processing plant's capacity to 2,500 tonnes per day.

In addition, a 15,000-meter surface and underground exploration drilling program is underway at the mine site, with 4,123 meters completed to date. The company plans to add underground drill rigs and publish the first batch of assay results in the fourth quarter of 2026.
