Tierra Group supervisó las 3 primeras fases de mapeo geológico e instalación de instrumentación y desarrolló un diseño de muro de tierra estabilizado mecánicamente en la mina Topia de Great Panther Silver en Durango, México.
Hydrogeologic Characterization Tierra Group provided hydrogeological support for data characterization and developed a conceptual and groundwater model to evaluate mine water inflows and the associated groundwater drawdown due to mine dewatering activities. Water Management Technical Review Tierra Group provided a…
Dry Stack Tailings Options Analysis Tierra Group performed an independent TSF expansion engineering design peer review. The review resulted in cost savings ($650,000) without compromising the facility's design integrity over the original design. Tierra Group also provided full-time CQA. Tierra…
Dam Safety Review Tierra Group performed a Dam Safety Review (DSR) for Nyrstar’s tailings storage facility (TSF) located in Campo Morado (Guerrero, Mexico). Tierra Group served as the Tailings Reviewer to ensure conformity with local regulations, the Nyrstar Tailings Storage…
Tierra Group began work at La Trinidad providing heap leach pad construction recommendations and a water balance. Tierra Group continued support with a heap leach pad expansion design, slope stability analyses, hydrologic analyses, diversion design, liner design, and leach solution…
Tierra Group designed and implemented a stability and safety monitoring plan for Torex Gold’s Morelos Mine dry stack tailings storage facility (TSF). The monitoring plan includes installing inclinometers and vibrating wire piezometers, and training operations staff to download instrumentation readings.…
Tierra Group was selected to assist Goldcorp with global Tailings Stewardship Strategy (TSS) implementation at all of Goldcorp’s active tailings sites in Latin America (Mexico, Argentina, and Guatemala). Tierra Group worked in conjunction with Goldcorp and another global engineering consulting…
The Bolivar mine is a 3,000 tonne per day underground mining operation in Chihuahua, Mexico producing copper, zinc, silver, and gold. Space constraints in mountainous terrain require dewatering tailings to reduce required area for tailings storage. Tierra Group is assisting…
Tierra Group performed a tailings storage facility safety (TSF) audit for the 90 m high upstream constructed tailings dam at La Negra Mine in Querétaro, Mexico. The project included a TSF dam inspection and Dam Safety Inspection Report (DSIR) containing operational…
Tierra Group performed an independent technical peer review of the Boleo Mine’s operating tailings storage facility design. In doing so Tierra Group identified several design modifications that when implemented for future stages will reduce sustaining capital cost expenditures by several…
Tierra Group performed an initial site visit to Coeur Mining’s Palmarejo Mine to conduct dam safety inspections of the tailings storage facility, environmental control dam, water diversion dam, and water diversion channel. Prior to the site visit, Tierra Group reviewed…
Tierra Group provided Tailings Stewardship Services including a dam inspection, slope stability analysis review and operational improvements for Endeavour Silver’s El Cubo tailings storage facility in Guanajuato, Mexico.
Topia Mine Phases 1-3Tierra Group supervised the first 3 phases of Geologic Mapping and Instrumentation Installation and developed a Mechanically Stabilized Earth Wall Design at Great Panther Silver’s Topia Mine in Durango, Mexico.
