Receives Final Molybdenum Assessment Results and Concentrate Specifications for the Vizcachitas ProjectVancouver, British Columbia--(Newsfile Corp. - June 23, 2021) - Los Andes Copper Ltd. (TSXV: LA) (\"Los Andes\" or the \"Company\") is pleased to announce that as a part of the ongoing Pre-Feasibility Study (\"PFS\") at the Vizcachitas Project in Chile (\"Vizcachitas\" or the \"Project\"), it has received molybdenum flotation results for the first 12 year samples, confirming the molybdenum recovery assumptions formed in the 2019 Preliminary Economic Assessment (\"PEA\") 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.Fernando Porcile, Executive Chairman of Los Andes, commented:\"We are delighted with the results of the PFS metallurgical test work as they have confirmed and improved the economical assumptions made in the PEA report. The results represent yet another accomplishment for the development of Vizcachitas, following the recent investment from Queen's Road Capital, the award of the environmental approvals for the drilling programmes and further metallurgical test work confirming a copper recovery rate of 91.4%. These updates illustrate the asset's significant potential. \"The out...
