Xanadu Mines provides update on Kharmagtai Copper-Gold Project

Xanadu Mines Ltd (ASX: $XAM) has announced successful metallurgical testwork for the Kharmagtai Copper-Gold Project in Mongolia, in partnership with Zijin Mining Group Co., Ltd. The testwork for assessing coarser grind options achieved compelling results, with up to 94% copper and 92% gold recovered in the HydroFloat stage, enabling a peak coarse reject of 43.8% by mass at 450um.

Executive Chairman and Managing Director, Colin Moorhead, on the testwork results

These results provide strong support for our Scoping Study uplift scenario using coarse ore flotation to improve overall project economics. This uplift is achieved through increasing throughput and accelerating mining and processing rates which ultimately accelerate revenue generation at Kharmagtai. It also promises to enhance the environmental sustainability aspects of Kharmagtai through the early separation of barren material and a coarser grind size, allowing for significant reduction in power and water requirements, and better tailings management. Given this separation method has been used successfully by bulk miners for over 20 years, we intend to leverage those learnings at Kharmagtai. We are now working with DRA, our process design engineers, to determine the optimal timing to include HydroFloat in the processing flowsheet, and maximise its beneficial impact for Kharmagtai.

Summary of Xanadu Mines' metallurgical testwork update

Xanadu Mines has reported successful metallurgical testwork for the Kharmagtai Copper-Gold Project, demonstrating compelling results for coarse ore flotation. The testwork achieved up to 94% copper and 92% gold recovery in the HydroFloat stage, with a peak coarse reject of 43.8% by mass at 450um. The company aims to leverage these results to improve overall project economics, increase throughput, accelerate mining and processing rates, and enhance environmental sustainability at Kharmagtai. Further studies and pilot testing are planned to optimize the inclusion of HydroFloat in the processing flowsheet and to inform the copper and gold recovery models, as well as operating cost estimates.
