This Preliminary Economic Assessment (PEA) outlines the recovery methods for the Coles Hill Uranium Property, focusing on an alkaline processing circuit designed to extract uranium from underground ore resources. The project utilizes a standard mill and yellowcake facility configuration, employing carbonate reagents for leaching to maximize internal water recycling and conserve reagents. The design assumes a 35-year mine life with an average head grade of 0.098% U3O8 and a mill leach recovery of 85%.

This section of the NI 43-101 Technical Report details the recovery methods for the Magistral Project, focusing on the modification and operation of an existing processing plant. The plant is designed to treat the Magistral tailings deposit with a nominal throughput of 1,000 tonnes per day. The flowsheet includes grinding, cyanide leaching, countercurrent decantation (CCD), SART (Sulfidation, Acidification, Recycling and Thickening), Merrill-Crowe precipitation, and cyanide destruction circuits.

The South Deep processing facility is designed to treat 330,000 tonnes of ore per month, with a name plate capacity of approximately 4 million tonnes per annum. The plant currently treats a combination of underground ore and reclaimed tailings, utilizing a semi-autogenous grinding (SAG) and ball mill circuit integrated with gravity recovery, thickening, leaching, CIP, elution, and electrowinning technology.

This report details the Hatch scoping study conducted in 2011 for the Kingash project, evaluating beneficiation, smelting, and refining options for the Kingashsky, Verkhnekingashsky, and Kuyovsky deposits. Three beneficiation options were analyzed: the Gipronikel flow sheet, the Valleriite Regrind flow sheet, and the Sulphidisation flow sheet. The study utilized mass and energy balances developed through METSIM™ modeling to assess capital and operating costs, ultimately selecting Option 2 (Valleriite Regrind) for the financial assessment due to its balance of recovery and cost.

The Goldex Mine Technical Report dated October 14, 2012, outlines the recovery methods and processing plant status for the Goldex Mine. The plant was commissioned in 2008 and operated until October 2011, when mining was suspended and the facility entered care and maintenance. The report details a feasibility study proposing a reopening in 2013 with a design throughput of 5,100 tonnes per day.

The Old Nic Mine processing plant is designed to achieve an overall gold recovery rate of 90%, utilizing a combination of gravity concentration and carbon-in-pulp (CIP) leaching. Approximately 70% of the gold is recovered as free gold in gravity concentrators, specifically Knelson concentrators and James Tables, while the remaining gold is processed through a conventional CIP circuit. This hybrid approach targets the high proportion of free-milling gold (60-70%) found in the Old Nic ore.
