This technical report details the recovery methods and processing facility plans for the SKO Project operated by Alacer Gold Corporation in Western Australia. The document outlines the performance of the existing 1.2 Mtpa Jubilee Processing Facility and proposes a new 2.5 Mtpa processing facility as part of the SKO Expansion Project (SKOEP). The existing facility utilizes a CIP circuit with gravity concentration, while the proposed facility aims to increase throughput and recovery rates through a hybrid CIL circuit and upgraded grinding equipment.

The Imperial Gold Project Preliminary Economic Assessment (PEA) outlines a proposed open pit mining operation utilizing a conventional heap leach system for gold recovery. The project is designed to operate on a 365-day, 24-hour basis, processing run-of-mine (ROM) material delivered directly from the open pit to the heap via mine haul trucks. The heap leach facility is engineered to accommodate multiple lifts, targeting a total heap height of 328 ft (100 m), with potential for expansion up to 492 ft (150 m). The process relies on a lined pad system with a containment structure to manage leachate and ensure environmental compliance.

Section 17 of the technical report outlines the selected mineral processing flowsheet for the Silver Sand project based on metallurgical testwork results. After evaluating several options including heap leaching, froth flotation, and agitated tank cyanidation, an agitated tank cyanidation process was chosen for the PEA base case. This selection prioritizes a conventional, low-risk approach to silver extraction, balancing capital cost, operating cost, and metallurgical efficiency.

The KCC process plant consists of two main facilities: KTC and Luilu, located near Kolwezi. Historically, the plant treated mixed ore (predominantly oxide with disseminated sulphide) from KOV and sulphide ore from KTO through separate circuits. The new KTC circuit processes mixed ore from KOV OP and Mashambe East OP to produce a sulphide prefloat concentrate and oxide tailings, which are pumped to Luilu. Sulphide ore from KTO continues in a separate circuit.

This section of the NI 43-101 Technical Report details the recovery methods for the Lac-des-Îles Graphite Quarry. The Qualified Person (QP) from Soutex conducted a site visit on October 4, 2021, observing the process plant which was not operating at the time but appeared well-maintained. The processing circuit includes crushing, grinding, flotation, gravity separation, and drying.

The Los Azules Project is a copper development project located in San Juan, Argentina, operated by McEwen Copper. The project utilizes an open-pit mining method with an initial throughput of 25 million tonnes per year, ramping up to 50 million tonnes per year by Year 3. The mine life is established at 20 years, with a processing operating life of 22 years. The ore body contains predominantly secondary and primary sulfide mineralization, including chalcocite and chalcopyrite, with an average total copper grade of 0.453%.

This technical report analyzes the enrichment studies of the oxidized ore from the Archut deposit. Based on the results, a specific technological model for processing is recommended to maximize recovery of gold and silver.

This NI 43-101 Technical Report presents the Feasibility Study for the Windfall Project, developed by Osisko Mining Inc. The project is an underground mine located in Quebec, Canada, targeting gold and silver commodities. The study outlines a comprehensive processing plant design based on laboratory-scale testwork performed at SGS Québec and SGS Lakefield laboratories. The plant is designed for a nominal throughput of 3,400 tonnes per day (tpd) with a maximum capacity of 4,080 tpd, utilizing a SABC grinding circuit followed by gravity recovery and carbon-in-pulp leaching.
