Executive Summary
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.
The selected process design is based on extensive test work and economic analysis, including comminution options that favored a SABC circuit with twin pinion mills. Key operational parameters include a primary grind size of 150µm, a copper recovery target of 85%, and gold recovery via gravity and CIL circuits. The facility includes dedicated infrastructure for concentrate dewatering, tailings management, and cyanide detoxification, reflecting a comprehensive approach to environmental and operational safety. The report details the equipment selection, reagent usage, and process control strategies required to achieve the design targets.
