Mineral Processing Circuit

The processing facility for the MacLellan and Farley Lake gold projects has been designed to ultimately process a nominal 2.63 Mt/a or 7.50 kt/d of a gold-silver mineralization. The mill will be built in two stages: in the first stage only sufficient equipment will be installed to permit the facility to process 1.31 Mt/a or 3.75 kt/d of material; the remaining equipment will be installed after four years to reach full capacity. This facility will produce an average of 145,092 troy oz/a of gold over the LOM and 198,763 troy oz/a of silver during the years when MacLellan is operation.

This NI 43-101 Technical Report details the recovery methods and plant design for the Blyvoor Gold Mine in South Africa. The plant is currently being ramped up to a full capacity of 40 kilotonnes per month (ktpm), with an expansion planned to 80 ktpm. The facility processes hard rock ore from underground operations, utilizing a comprehensive flow sheet that includes crushing, milling, gravity concentration, carbon-in-pulp leaching, elution, and electrowinning.

International Enexco’s October 2013 study crushes ore to 100% minus one inch, leaches it with weak sulfuric acid, and pumps solution at 7,000 gpm through a four-pond system to two parallel solvent extraction trains.

The Generation Mining Limited Marathon Property Pre-Feasibility Study (PEA) details a proposed open-pit mining operation in Ontario, Canada, targeting copper and platinum group metals (PGMs). The project utilizes a conventional crushing and grinding circuit followed by a split copper-PGM flotation flowsheet. The process plant is designed to treat 5 million tonnes per annum (Mtpa) in the first five years, with an expansion to 8 Mtpa planned for production year six onwards.

This NI 43-101 Technical Report and Preliminary Economic Assessment outlines the recovery methods and processing design for the Kwanika-Stardust Project. The plant is designed to process an average of 22,000 tonnes per day of mineralized material, with a total mill life of approximately 94 million tonnes. The flowsheet is based on preliminary testwork and financial evaluations, utilizing standard technologies widely used in copper flotation plants. The project focuses on the recovery of copper and gold from sulphide ore through a comprehensive comminution and flotation circuit.

This technical report section outlines the conceptual recovery methods for the Norra Kärr Project, developed by Tasman Metals Limited. The project focuses on the extraction of rare earth elements (REE), yttrium, and zirconium from peralkaline intrusive rocks. A conceptual flowsheet was developed by J.E. Litz and Associates, LLC, incorporating test work from SGS-Lakefield, the Geological Survey of Finland (GTK), and internal bench testing. The process is designed to handle the specific mineralogy of the deposit, which includes acid-soluble gangue minerals like natrolite and nepheline.
