Mineral Processing Circuit

This 2012 Pre-Feasibility Study outlines the processing methodology for the Trinidad/Taunus Project, focusing on a heap leach recovery circuit. The proposed operation involves crushing run-of-mine ore to a fine size, agglomerating it with cement, and stacking it on a lined pad for cyanide leaching. The design targets an average throughput of 4,300 tonnes per day, with an annual capacity of 1.55 million tonnes.

This NI 43-101 Technical Report outlines the recovery methods for the Battery Hill Manganese Project located in New Brunswick, Canada. The project focuses on the production of High Purity Manganese Sulphate Monohydrate (HPMSM), a specialty product used primarily for battery applications. The process design is based on the reactivity of manganese silicate mineralization to dilute sulphuric acid, supported by developmental test programs and mass balance modeling using Metsim.

Quebec Iron Ore (QIO) operates the Bloom Lake Mine facilities, which include two distinct concentrator phases. Phase I was restarted in 2018, while Phase II commenced operations in 2022. The combined design yearly production capacity for the facility is 15 million tonnes per year (Mtpy) of concentrate, sourced from the Pignac, West, and Chief’s Peak pits. The processing flowsheets were developed based on initial Phase II designs and extensive testing and piloting results conducted in partnership with Mineral Technologies.

This NI 43-101 Definitive Feasibility Study outlines the Stage One project for Minera Salar Blanco located in the Atacama Region of Chile. The project focuses on the extraction of lithium from brine resources within the Salar de Maricunga area. The facilities are designed to produce an average of 15,200 tons per year of battery-grade lithium carbonate over a 20-year mine life. The process utilizes solar evaporation ponds to concentrate lithium-rich brine before further purification and precipitation in a production plant.

The Empire State Mines (ESM) concentrator, originally commissioned in 1970 and last shut down in 2008, was refurbished in late 2017 and resumed processing mineralization in 2018. The facility is designed to handle 5,000 short tons per day, though current operations run on a reduced schedule of one shift per day, four days per week, processing between 10,124 and 11,375 tons per week. The mine operates underground, with mining production typically not exceeding 2,275 tons per day, projected to peak at 2,800 tons per day in 2028.
