Los Andes Copper Ltd. announced that as a part of the ongoing Pre-Feasibility Study at the Vizcachitas Project in Chile, it has received molybdenum flotation results for the first 12 year samples, confirming the molybdenum recovery assumptions formed in the 2019 Preliminary Economic Assessment and confirming that the Vizcachitas operation will produce clean concentrates. As a part of the PFS metallurgical test work, representative samples of the first 12 years of operation were sent to SGS Minerals for rougher, cleaner-scavenger, and selective rougher copper-molybdenum flotation. Based on the PFS test work results and for the first 12 years of operation, the molybdenum recoveries are 90.3% in the rougher stage, 95.8% in the cleaner-scavenger stage, and 90.6% in the copper- molybdenum selective flotation; resulting in a projected overall molybdenum recovery of 76%, a slight improvement from the 75% recovery assumed in the PEA. Furthermore, analysis for the final copper concentrates confirmed that Vizcachitas will produce clean concentrates. Projected results show that final copper concentrate grades are between 22.9% and 24.4% copper, and a credit may be obtained for silver at grades between 46 to 65 grammes per tonne. No elements are present at penalty levels in the copper concentrates as the grades for antimony and bismuth are below 0.04% and 0.01% respectively, first 12 year weighed average of arsenic grades is 0.16% and mercury grades are approximately 5.2 ppm.
