This Preliminary Economic Assessment (PEA) outlines the conceptual processing flowsheet for the Lac à l’Orignal Phosphate Property. The project involves open pit mining of mineralized material with a nominal capacity of 10,500 tpd. The process is designed to recover three distinct commodities: high-grade apatite for phosphoric acid production, high-purity magnetite, and moderate-grade ilmenite.

The GMC mineral processing plant, located at Cata, operates with a throughput of approximately 973 tonnes per operating day. The facility processes ore delivered from GMC’s mines, including San Ignacio and Santa Margarita, to produce a concentrate of iron sulphide (pyrite) enriched with gold and silver. The processing circuit consists of five stages: crushing, milling, flotation, thickening, and filtering. The plant has been in operation since at least 2006, with production data recorded through August 31, 2017.

This section of the NI 43-101 Technical Report details the recovery methods for the Barry Open Pit Project, utilizing the existing Bachelor Plant. The concentrator is designed for an initial throughput of 800 tpd, with a planned expansion to increase feed to 1,200 tpd to accommodate Barry mineralized material. The development of the new flowsheet prioritizes the use of existing equipment and building space where possible.

This technical report details the recovery methods and processing plant operations for the Dalny Mine Complex, prepared for New Dawn Mining Corp in December 2012. The mine operates as an underground facility where mineralized material is transported by tractors or hoisted to a grizzly. The processing circuit begins with crushing, where oversize material is processed by a 14/24′ Telsmith Jaw crusher and further reduced by Symons cone crushers in closed circuit with vibrating screens. Run of mine material and dump sands are treated through parallel ball mill circuits, with capacities ranging from 120 tpd to 1,000 tpd depending on the mill size and feed type.

The proposed potash processing plant is designed to produce up to 300,000 tonnes of potash annually, based on overall wellfield development. The facility targets two standard products: crystal granular and white standard. The processing plant is scheduled to operate at up to 8,000 hours per year, utilizing mechanical evaporation as the primary recovery method for KCl from sylvinite ore.

This section of the NI 43-101 Technical Report outlines the recovery methods considered for the Douay West Gold Property. Due to the current estimates of the quantity of potential mill feed, the construction of an on-site processing facility is not justified. Instead, the study evaluates potential off-site processing facilities within a moderate trucking distance.

The Arctic Project Feasibility Study Technical Report outlines the process plant design for the Arctic deposit, hosted in the Ambler Sequence within a VMS belt. The plant is designed to treat MS and SMS ores with a throughput of 10,000 t/d, operating two 12-hour shifts per day with 92% availability. The process will produce three concentrates: copper, zinc, and lead, with gold and silver recovered in the copper and lead concentrates.

The technical report section 17.0 outlines the proposed recovery methods for the Ilovitza porphyry Cu-Au system. The strategy involves a dual approach based on ore type: oxide material is targeted for leaching, while sulfide and mixed ore are processed via flotation. This separation allows for the recovery of copper, gold, and molybdenum from the sulfide circuit, with gold recovered in the copper float and a dedicated molybdenum circuit.

This Pre-Feasibility Study (PEA) by SRK Consulting evaluates four processing options for the Boa Fé gold project. The options range from conventional gravity and flotation with cyanidation to alternative lixiviants such as thiosulphate and halogens, largely driven by potential EU restrictions on cyanide usage. Recovery estimates vary significantly, with Options A and B at 85.5%, Option C at 73%, and Option D at 95%.
