Elcora/Ermazon plans to develop the Sidi Yahia Outat operation in three distinct stages. Initially, the company intends to sell raw ore to local mineral dealers at LME prices. Subsequent phases involve the construction of processing infrastructure to increase value.

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.

The Zafranal Project in Peru features a dual processing strategy comprising a concentrator and a dump leach/SX-EW facility. The concentrator is designed to process 44,000 t/d of copper and gold-bearing plant feed material from an open pit operation, producing a marketable copper flotation concentrate containing 28% copper and approximately 3 g/t of gold. The metallurgical processing procedures were based on test work performed at G&T and Plenge.

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 report details the recovery methods for the Los Ricos North project, designed to treat both oxide and sulphide deposits. The process plant is designed for a nominal throughput of 8,000 tpd. Initially, four oxide deposits will be processed via conventional tank leaching and Merrill Crowe precipitation. Commencing in year nine, the plant will transition to processing sulphide material from the Orito Deposit via conventional flotation operations, at which point the leaching and Merrill Crowe operations will shut down.

This technical report outlines the recovery methods for the Yellow Giant mineralization on the Banks Island Mineral Property. The report establishes that gold is strongly associated with sulphide mineralization, specifically massive sulphides, which allows for effective separation from low-density gangue using gravity methods. Heavy Liquid Separation (HLS) testing conducted in 2011 demonstrated high gold recoveries of 87.6% at a coarse crush size of ¼ inch, supporting the viability of a gravity process.
