Mineral Processing Circuit

The Las Chispas Project Technical Report outlines a feasibility study for a gold and silver processing plant with a nominal throughput of 1,250 t/d. The flowsheet utilizes a conventional comminution circuit featuring a primary jaw crusher and a single-stage SAG mill closed with cyclones. The process includes bulk rougher flotation to generate a high-grade concentrate, followed by cyanide leaching circuits for both the concentrate and flotation tailings.

This section of the NI 43-101 Technical Report details the selected recovery methods for the Bamastar Graphite Project. The process design is based on a phased approach flowsheet optimized for graphite recovery while minimizing initial capital expenditure and operating costs. The design prioritizes equipment suitability, reliability, and ease of maintenance, with a plant layout that facilitates concurrent construction and operational access. The flowsheet is designed to handle both soft oxide material in the early years and harder fresh material in Phase 2.

Section 17 of the 2020 Preliminary Economic Assessment Study outlines the recovery method for the James Bay Niobium Project. The process selection was driven by metallurgical test work and current industry technology, designed for an annual ore production of 2,400,000 tonnes per year with a plant availability of 93%. The flowsheet incorporates a gravity circuit to remove approximately 42% of the mass early in the process, which minimizes energy requirements and reagent costs while limiting niobium losses.

This NI 43-101 Resource Update details the Preliminary Economic Assessment (PEA) for the Graphite One project, prepared by TRU Group in June 2017. The project envisions a vertically-integrated manufacturing model for high-grade coated spherical graphite, combining mining and mineral processing at the Graphite Creek property in Alaska with purification and value-added processing at a downstream Product Manufacturing Plant near a port.

This report outlines the recovery methods for the Decar Nickel Project, focusing on the beneficiation of awaruite ore. The process design is based on test work conducted by SGS, utilizing physical separation methods due to the high specific gravity and magnetic susceptibility of awaruite. The flowsheet includes three stages of crushing and grinding, magnetic separation, regrinding in tower mills, and gravity concentration using Knelson concentrators.

The Chidliak Project Preliminary Economic Assessment outlines a preliminary process flowsheet for the extraction and recovery of diamonds from CH-6 and CH-7 kimberlite material. Due to limited metallurgical data, the flowsheet relies on proven Northern Canadian kimberlite processing techniques designed for an Arctic operating environment. The plant is designed to treat 2,000 tonnes per day with a mine life of up to 13 years based on a potential mineable resource of 9.5 Mt.

This NI 43-101 Technical Report details the process design for the Farim Phosphate Project beneficiation plant and Mineral Terminal facility. The design utilizes physical separation processes to classify feed by size and reject impurities, producing a filtered bulk concentrate. The plant is designed to accommodate material from both the South pit (Years 1-7) and North pit (Years 8-25), with a nominal throughput of 219 dry t/h. The process includes scrubbing, desliming, classification, and dewatering stages before the concentrate is trucked to the Mineral Terminal for drying and ship loadout.

This NI 43-101 Technical Report details the processing operations at the Ahafo South mine in the Republic of Ghana, operated by Newmont. The facility commenced operations in 2006 and is designed to treat a blend of oxide and primary ore. The current throughput is projected to vary between 7.3 and 10.6 megatonnes per annum, depending on the ore blend from open pit and underground operations. The report outlines the existing Line 1 processing circuit and the planned Line 2 expansion project (AME), which aims to increase capacity by 3.5 Mt/a through the installation of new crushing and grinding equipment.
