Mineral Processing Circuit

This Pre-Feasibility Study (PEA) outlines the recovery methods for the Nico Young Project, located near Young, Australia. The project focuses on the extraction of Nickel and Cobalt from laterite ore bodies, specifically Limonite, Saprolite, and Serpentinite types. The proposed processing plant is designed for an annual throughput of 3 million tonnes per annum (Mtpa), utilizing a heap leaching circuit followed by a solvent extraction refinery to produce high-value nickel sulphate and cobalt sulphide products.

This technical report outlines the recovery methods for the Cobre Panamá Project, a large-scale open-pit sulphide mine located in Panama. The processing plant is designed to treat ore from multiple pits, including Botija, Colina, and Valle Grande. The initial throughput in 2018 is planned at 190,000 t/day, increasing to a nominal 246,575 t/day by 2023, with a design capacity of up to 274,000 t/day.

The Young-Davidson mine is an operating underground facility located in Matachewan, Ontario, with a processing plant commissioned in 2012. The mill processes ore from both the underground mine and low-grade surface stockpiles from a former open pit. The facility has a design throughput capacity of 8,000 tonnes per day (tpd), which was increased from an initial 6,000 tpd following a mill expansion study in 2012.

This technical report section details the recovery methods employed at the Summit Mine operated by Lordsburg Mining between March 2010 and October 2013. The processing plant was designed to produce two separate products for sale to local and overseas smelters: a precious-metal-bearing silica flux and a gold-silver flotation concentrate. The facility utilized a combination of crushing, grinding, and flotation circuits to upgrade the ore, with operations historically shipping significant quantities of both flux and concentrate to smelters in Arizona.

This section of the NI 43-101 Technical Report details the recovery methods for the Roca Honda Project. The mineralized material produced from the Roca Honda mine is transported to the Energy Fuels Inc.-owned White Mesa Mill near Blanding, Utah, for processing. The mill, originally built in 1980, is capable of processing 2,000 stpd but is designed for the Roca Honda project at 1,800 stpd.

The Lanigan mine has been in operation since 1968, producing high-grade finished potash products for agriculture and industry. The facility utilizes both flotation and crystallization methods to concentrate potash ore into near-pure KCl products. Production data from 2012 to 2014 shows annual output ranging from 1.653 to 2.241 million tonnes with an average grade of approximately 60.87% K2O.
