Tierra Group provided slope stability analysis for Agnico Eagle’s dry stack tailings storage facility containing 330,000 tonnes of tailings.
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 reviewed and provided pit slope recommendations and conducted hydrological assessments for the Resource 1 and 2 deposits water management system at Troy Resources’ Karouni Mine (Karouni). Advanced pre-feasibility level recommendations for pit development were provided based on benchmarking…
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 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…
Midas Gold’s project is located in the remote central Idaho Rockies near the town of Yellow Pine. It is a brownfields gold-antimony project featuring three open pits and an anticipated 22,000 tpd plant throughput, along with challenging terrain and environmental…
Tierra Group provided a Third-Party review of the Hermosa Project Tailings Storage Facility Design and Construction stages 1 & 2 in Patagonia, Arizona
Tierra Group evaluated the Tajo Crimea Pit’s geotechnical and hydrogeological characteristics to determine in-pit tailings storage feasibility. The project scope defined geotechnical and hydrogeologic site conditions through field investigations and in-situ pump testing. Tierra Group developed a 3D groundwater model…
Tierra Group provided a raise design for Doe Run's Brushy Creek tailings embankment, a facility first commissioned in 1973. Cone penetration testing, liquefaction analysis, seepage modeling, and slope stability modeling were performed for the embankment. Hydrology, spillway design, and impoundment layout…
Dam Breach Analyses Tierra Group prepared a DBA to evaluate potential downstream impacts due to a hypothetical failure (breach) in three components of Empire State Mines (ESM) tailings storage facility (TSF): North Dam (ND), South Dam (SD), and West Perimeter…
Tierra Group performed a Dam Safety Review (DSR) including geotechnical investigations and seepage and slope stability analyses for a 20-m high TSF at this 300‑tpd underground polymetallic mine. The audit was prepared following the Mt. Polley tailings dam failure in…
