This NI 43-101 Technical Report outlines the Pre-Feasibility Study (PFS) for the Kharmagtai Project, a development-stage open-pit mine operated by Xanadu. The project design focuses on a staged production strategy targeting a peak milled tonnage of 52 Mt/y over a 26-year mine life. The processing plant is designed to handle both sulphide and oxide ore types, utilizing a comprehensive flowsheet that includes comminution, flotation, gravity concentration, and carbon-in-leach (CIL) circuits. The design incorporates significant contingency measures, such as parallel trains for Stage 2 expansion, to ensure operational robustness and economic viability.

This NI 43-101 Technical Report details the development and operational status of the Oyu Tolgoi project in Mongolia, managed by the Oyu Tolgoi Joint Venture (OTLLC). The project is currently in a phased development stage, with Phase 1 commissioned in 2013 and Phase 2 focused on integrating underground feed from the Hugo North deposit. The concentrator facilities are designed to process ore from both the Oyut open pit and the Hugo North underground mine, utilizing a conventional semi-autogenous grind (SAG) mill and ball mill circuit followed by flotation.

This section of the NI 43-101 Technical Report details the recovery methods employed at the San Martin Mill. The facility utilizes a conventional cyanidation process combined with the Merrill Crowe recovery method. The mill has a rated capacity of 1,100 tpd, though current operations average around 650 tpd based on data from April 2017 to April 2024. During this period, the mill achieved average recoveries of 86% for gold and 55% for silver.

This NI 43-101 Technical Report details the processing facility and operational status of the Langer Heinrich Uranium Project (LHU) in Namibia, operated by Paladin Energy Limited. The facility was historically operational until 2018 and is currently undergoing a Restart Project to resume production. The report outlines the beneficiation and hydrometallurgical circuits, including ore handling, scrubbing, classification, leaching, ion exchange, and precipitation processes. Historical data from 2014 to 2018 indicates uranium recoveries generally above 80%, with recent years achieving 85-90%.

This NI 43-101 Technical Report details the recovery methods and processing plan for the Great Atlantic Salt Project, operated by Atlas Salt Inc. The project involves underground mining of salt deposits to produce de-icing salt conforming to ASTM D632-12 specifications. The processing plant is designed to operate underground, utilizing conventional dry screening and crushing methods to achieve a maximum annual production rate of 4.0 million tonnes per annum (Mtpa). The facility includes a 190 m long processing area located at the bottom of a conveyor incline tunnel, equipped with double roll crushers and inclined vibrating screens.
