Receives Improved Results for Dry Stacked Tailings at the Vizcachitas ProjectVancouver, British Columbia--(Newsfile Corp. - November 30, 2020) - Los Andes Copper Ltd. (TSXV: LA) (\"Los Andes\" or the \"Company\") is pleased to announce that it has received additional positive results from the ongoing Pre-Feasibility Study (\"PFS\") metallurgical testwork. These results show improved filtration rates for both the fine and coarse fraction tailings compared to the previous testing. These results reinforce the decision to adopt dry stacked tailings for the Company's Vizcachitas Project in Chile (\"Vizcachitas\" or the \"Project\").The News Release of October 22, 2020, regarding PFS metallurgical testwork carried out by SGS, demonstrated that the Vizcachitas tailings are amenable to being filtered and dry-stacked. The same coarse and fine representative tailings samples were sent to the TAKRAF laboratories, a global leader in filtration equipment with a strong operational track record, for further settling and filtration assessments. The TAKRAF testwork tested various different settling and filtration parameters, including those previously tested. The studies demonstrated that for the coarse fraction vacuum filtration, the rates improved from 1.9 t/h/m2 to 3.4 t/h/m2 when compared to the previous results. For the finer fraction, the settling velocities improved from 8.4 m/h to 16.0 m/h and the pressure filtration rates improved from 0.6 to 0.7 t/h/m2. The expected cake moistures for both filtration technologies are 15%. These improved results reinforce the previous assessment. These positive results mean that the Vizcachitas project, processing 110,000 tonnes per day of ore, would only need to use eleven standard 162 m2 belt filters and four 2.5 m by 2.5 m pressure filters for the tailings dewatering operation. Other operations in the world are successfully operating with a similar filter arrangements. Tailings filtration reduces water consumption by 50% when compared to thickened tailings disposal alternatives. Furthermore, filtered tailings can be handled by trucks, conveyors and shovels, eliminating the need for the construction and operation of a tailings dam. The adoption of this technology puts the Vizcachitas Project at the forefront of the environmentally responsible practices being adopted for the futur...
