Mineral Processing Circuit

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 2021 NI 43-101 Technical Report for the Woxna Graphite project by Zenito outlines a Pre-Feasibility Study (PEA) for the Woxna Concentrator and a Value Added Processing (VAP) facility. The project involves processing 160,000 tpa of Run of Mine (RoM) graphite ore with a grade of approximately 9.18% Cg. The concentrator produces graphite concentrate which is then transported to the VAP in Edsbyn for further processing into Cathode Spherical Graphite (CSPG) and micronized graphite.

Katanga Mining’s 2019 technical report describes the conversion of the Kamoto Copper Company plants at Kolwezi to a whole ore leach flowsheet, with cobalt hydroxide capacity planned to rise from 30 kt/y to 40 kt/y.

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.

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.
