Results Include 331m grading 0.63% Copper Equivalent on the largely undrilled Northeastern Side of the Deposit

Vancouver, British Columbia, London, UK and Santiago, Chile (May 30, 2022) – Los Andes Copper Ltd. (TSXV: LA) (OTCQX: LSANF) (“Los Andes”, “LA” or the “Company”) is pleased to report continued consistent positive results from recent drilling completed at the Vizcachitas Copper Project in Chile. The new results include 331 meters grading 0.63% Copper Equivalent (0.55 % Copper, 212 ppm Molybdenum and 1.28 g/t Silver) in hole CMV 012B on the northeastern edge of the deposit where almost no prior drilling has been completed. The results also include 122 meters grading 0.59% Copper Equivalent on the western edge of the deposit (0.55 % Copper, 223 ppm Molybdenum and 1.72 g/t Silver) in hole CMV 011.

The drill results continue to expand a Tier 1 large, advanced copper deposit, with a Pre-Feasibility Study (“PFS”) in progress, in a copper market with few development projects in the pipeline and a multi-million tonne supply deficit looming. Projects like Vizcachitas are expected to be in high demand by copper producers as they advance towards the development stage to help fill the supply gap.

The drill core assay results reported today will be also incorporated into the new resource assessment for the PFS targeted for the fourth Quarter 2022. 

R. Michael Jones CEO of Los Andes said, “the drill results continue to show that the limits of the Vizcachitas Porphyry Copper deposit still have not been determined. On the east, west and southern areas we have yet to close-off the deposit with drilling. Our recent previously announced results of 152 meters of 1% Copper Equivalent in the south (CMV 009) and the results announced today on the western and eastern sides, show that further drilling is required to determine the full scale of the deposit.”

Vizcachitas is a classic porphyry copper deposit in the same setting as some of the largest copper mines in the world, which surround it to the north and south in Chile. Current Resources, as estimated in the Preliminary Economic Assessment (the “PEA”), which will be updated with the new drilling in 2022, are Measured Resources of 254.4 million tonnes having a grade of 0.489% copper equivalent and Indicated Resources of approximately 1.03 billion tonnes having a grade of 0.442% Copper Equivalent.

Future milestones for the Company include additional drilling assay results in the coming weeks and completion of the PFS in the fourth Quarter of 2022. Vizcachitas represents one of the few truly Tier 1 copper assets, as being a large resource in a leading jurisdiction for copper development with no major company holdings or offtake commitments. Los Andes Copper owns 100% of the Vizcachitas Project.

* Copper Equivalent grade has been calculated using the following calculation: CuEq (%) = Cu (%) + 0.000333 x Mo (ppm) + 0.00826 x Ag (g/t), using the metal prices: 3.00 USD/lb Cu, 10.00 USD/lb Mo and 17.00 USD/oz Ag. No allowance for metallurgical recoveries has been considered. These are the same reference prices as in reporting of 2019 PEA. This means that the reported intercepts can be compared directly with the results published in the PEA. Approximate relative value on the PEA pricing is 93% Copper, 6% Molybdenum and 1% Silver. 

All thicknesses from the drill hole intersections are down-hole drilled thicknesses. True widths will be estimated as the deposit model is updated and information becomes available. Hole CMV-008 was drilled in an exploration area located on the southwestern side of the project site.   

The Company is preparing a filing for the Environmental Court in Chile on the issues raised in a recent injunction that suspended drilling. Following considerable detailed work and documentation, the Company plans to submit substantial evidence to demonstrate that the drilling project can continue, in accordance with the Company’s permits, with no significant negative effects to fauna and the environment. Los Andes Copper welcomes continued open dialogue with all stakeholders in a climate of mutual respect to protect the environment and maximize the value of the project.

About Los Andes Copper Ltd.

Los Andes Copper Ltd. is an exploration and development company with an 100% interest in the Vizcachitas Project in Chile. Los Andes Copper Ltd. is listed on the TSX-V under the ticker: LA.

The Project is a copper-molybdenum porphyry deposit, located 120 kilometres north of Santiago, in an area of very good infrastructure. The Company’s Preliminary Economic Assessment (the “PEA”), delivered in June 2019, highlights that the Project has a post tax NPV of $ 2.7 billion and an IRR of 26.7%, based on a $3.50 per pound copper price.

Please refer to the technical report, compatible with NI-4301,  dated June 13, 2019, with an effective date of May 10, 2019 and titled “Preliminary Economic Assessment of the Vizcachitas Project”, prepared by Tetra Tech.

The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.

Qualified Person (“QP”) and Quality Control and Assurance

Antony Amberg CGeol FGS, the Company’s Chief Geologist, is the qualified person who has reviewed and approved the scientific and technical information contained in this news release. The QP has validated the data by, supervising the sample collection process, through chain of custody records and inspecting the detailed technical data and quality control and assurance information.

Los Andes Copper has a strict Quality Assurance and Quality Control (“QA QC”) protocol, which is consistent with industry best practices. There is a strict chain of custody from the project site to laboratory via the Company’s core cutting facility. The QA QC protocol includes the insertion of field duplicates, coarse duplicates, pulp duplicate, pulp and coarse blanks and Certified Reference Materials supplied by Ore Research and Exploration, Australia. 

The core was analysed by ALS in Lima, Peru. All samples were assayed using the method ME-MS61, a four-acid digestion with an ICP-MS finish. Samples with grades above 0.7 % Cu were analysed using ALS method Cu-OG62, a four-acid digestion with an ICP-AES finish. The Company uses a program of detailed QA QC and monitors the performance of the laboratory.
