An independent technical report for the PFS, prepared in accordance with NI 43-101, will be available under the Company’s SEDAR profile within the next 45 days.

Los Andes Copper’ CEO, Santiago Montt, commented on the PFS:

I am extremely pleased to announce the results of the Pre-Feasibility Study for the proposed Vizcachitas mine in Chile. It shows that Vizcachitas is clearly a Tier 1 asset that has the potential to join the ranks as one of the largest and most profitable copper mines in Chile.

The new mine design incorporates a number of optimizations including expanding access works, allowing for a faster ramp-up of production and minimizing uphill material movement and haulage distances. This has reduced the OPEX and led to a shorter payback further strengthening the economics of the Project. Our new sustainable and responsible design considers the use of HPGR to reduce energy consumption, dry-stacked filtered tailings to reduce water consumption and footprint, and desalinated water.

Vizcachitas benefits from being situated in a country with an established mining industry and in close proximity to existing infrastructure including power, roads and ports. All of these factors have enabled the Project to meaningfully reduce its initial CAPEX requirement. There is also a skilled labor force in the nearby towns and cities of Putaendo, San Felipe and Los Andes.

The Project is economically robust with the potential for considerable upside through further drilling to upgrade the Inferred Resource to Measured and Indicated, thereby bringing them into the mine plan.”

Los Andes Copper’ Chairman, Eduardo Covarrubias, commented on the PFS:

“The lack of new discoveries of this scale over the last 10 years and the increasing demand for copper highlights the importance of projects like Vizcachitas. The PFS demonstrates a robust, economically attractive project with long mine life and potential for significant further upside.

The study focused on ensuring Vizcachitas would lead the way in sustainable mining, and we are delighted to announce that our three key targets: to reduce water usage, power consumption and the footprint of the Project have all been met, allowing us to deliver a mine that minimizes its impact on the environment.

Project Description

The Vizcachitas Project is located in the Andes Mountains, in the Province of San Felipe, Fifth Region of Chile, approximately 150 km northeast of Santiago, Chile, and 46 km northeast of Putaendo, San Felipe Province. The Project is 100% owned by Los Andes Copper Ltd., a company based in Vancouver and listed on the TSX Venture Exchange. The Project is located at just 1,950 m.a.s.l., in proximity to other world-class copper-molybdenum porphyries that belong to the same metallogenic belt.

The Vizcachitas Project is a mineralized copper-molybdenum porphyry system associated with a complex

of hydrothermal breccias and porphyries within Miocene volcanic rocks. The Vizcachitas Project contains Measured and Indicated Resources of 14.801 billion pounds CuEq (Measured Resource of 2.605 billion lbs copper, 84 million lbs molybdenum and 11 million oz silver, and Indicated Resource of 10.416 billion pounds of copper, 442 million lbs of molybdenum, and 43 million oz of silver) and Inferred Resources of 15.444 billion pounds CuEq (13.747 billion lbs of copper, 495 million lb of molybdenum, and 55 million oz of silver). It is one of the largest undeveloped copper projects in South America not controlled by a major mining company.

The PFS contemplates that Vizcachitas would be mined using conventional open pit methods. From the open pit the ore would be trucked to a concentrator designed to process 136,000 tonnes per day of ore. The ore would be fed into a three-stage crushing plant using HPGR technology as the tertiary crusher. The ore would be crushed to 240 microns, and sent as a slurry to the flotation stage located further down the valley. The flotation stage would produce a clean copper and silver concentrate and a separate molybdenum concentrate. The tailings produced in the flotation stage would be thickened and filtered to 15% moisture. The filtered tailings would then be co-mingled with the mine waste rock and deposited in a combined tailings/waste rock facility.

The Vizcachitas Project is designed to use desalinated water, supplied by a third-party consortium. Power would be supplied via 60km line connecting to the national grid. Concentrate would be transported in rotainers (sealed rotating containers) by truck 145km to the Port of Ventanas with the Ports of Valparaiso and San Antonio as additional options. There are 35km of existing roads that would require upgrading between Vizcachitas and Putaendo. Rail transportation from San Felipe to any of the three ports is a further alternative to be evaluated.

Social & Environmental

The PFS was designed to adopt the latest proven sustainable mining technologies. The focus was on securing a desalinated water supply and reducing water consumption, power consumption and the footprint of the Project.

All of these targets have been met. The Company has signed a letter of intent with a desalinated water consortium to secure a water supply for the Project removing any concerns over the use of continental water in an area that has been heavily impacted by drought. The plan under discussion with the consortium also includes providing water at preferential rates to community groups along the pipeline route in the Putaendo and Petorca valleys.

The use of dry-stacked filtered tailings reduces the water consumption of the Project by approximately 50%, (compared to thickened tailings). It also reduces the footprint of the Project by 500 hectares compared to the PEA and is now designed to be situated in only one valley.

The introduction of HPGR technology has reduced power consumption by 25% vs a SAG circuit that was previously considered in the PEA.

The Company has projected low CO2 emissions. Scope 1: 178,389 t CO2e/year, or 1.02 t CO2 per t CuEq produced; potential to have Scope 2 at zero as long as the power market continues to have renewable availability for the full energy supply of the Project. The Company will continue to look for opportunities to further reduce Scope 1 emissions.

Communication with the local communities and public authorities has continued throughout the PFS with the Community and Corporate Affairs team working closely with all interested parties.

The PFS is based on open pit mining methods with conventional drilling, blasting and loading performed on 15m benches. Continuous mineralization occurring near the surface facilitates the start and lowers the strip ratio, avoiding a large initial CAPEX to access the grade.

The mine would use an autonomous fleet taking advantage of the technology’s proven productivity improvements, cost and energy savings. Extensive early access works would allow a faster ramp up of production.

The open pit would have a mine life of 26 years, operating 365 days a year with a life of mine strip ratio of 2.33:1 (including pre-stripping). The production plan would be based on the steady state processing of 49,640,000 tonnes per annum of ore. Once steady state production is reached, variations in cash-flow are due primarily to variations in head grade, strip ratio and recoveries.

The mined production profile, followed by the milled production profile, is presented below. Ores below variable mill cut-off grade are stockpiled in either high-grade, medium-grade or low-grade stockpiles and are subsequently rehandled and combined with mine feed to the mill.








Vizcachitas is a copper-molybdenum porphyry where its main copper species are primary sulphides. An optimal liberation is achieved at a P80 of 240 microns. Low presence of clays favours flotation and water recovery performance. These key ore characteristics allow the Project to:

  • Consume less energy in the grinding stage compared with other porphyries (10.8 kWh/t in the grinding stage and 16.6 kWh/t overall) with the use of the HPGR technology and with a target P80 of 240 microns.
  • Achieve recoveries over 90% (average of 91.1%), producing clean concentrates.
  • Use of filtered tailings technology to achieve a cake moisture of 15%. This results in substantial reductions of water consumption (below 0.2 m3/t) and dry tailings that do not require building a tailings dam, thus reducing the Project footprint, environmental impact and seismic risks.

The low altitude of the Project avoids the need for de-rating of equipment. Gravitation will be used to send ore from the crusher to the flotation plant which will also reduce energy consumption.

The Flotation area will be located downstream from the crushing plant in a natural plateau on the east side of the valley.


The Project is located in an infrastructure-dense region. Connection to the national grid would be via a 60km line. Concentrates would be transported in rotainers by truck 145km to the Port of Ventanas with the Ports of Valparaiso and San Antonio as additional options. There are 35km of existing roads that would require upgrading between Vizcachitas and Putaendo. Rail transportation from San Felipe to any of the three ports is a further alternative to be evaluated.

A site camp is not required for lodging due to a reduced commuting time to nearby towns and cities (Putaendo, San Felipe and Los Andes) which have skilled mining workforces.

Tailings would be dry stacked in layers with the mine waste rock in a co-mingled configuration. The Tailings Storage Facility would be located across the valley allowing the loaded waste mine trucks to operate in a favourable slope. The use of dry-stacked filtered tailings would reduce water consumption by approximately 50% (from the previous design), limit its footprint to one valley, and discard the use of tailings dams, minimizing seismic risk and environmental impacts.

The Rocin River would be diverted by a 40m high dam and a 5m diameter and 16.2km long tunnel. The Company signed a Letter of Intent with Desala Petorca SPA, a water supply company which will provide desalinated water to the Project thereby removing any concern over use of continental water in drought afflicted area.

Future opportunities and value enhancements

The PFS identified a number of potential optimizations to the Project. These include:

  • Further drilling to reclassify Inferred Resources to Measured and Indicated Resources and so incorporate them into the mine plan
  • Further drilling to define the extent of the mineralization both laterally and at depth

Both can potentially extend the mine life without expanding plant and infrastructure.

The use of rotainers to transport the concentrate creates a number of options to transport the concentrate to port. The base case currently contemplates trucking to the Port of Ventanas. Rotainers open the possibility of accessing (with minor incremental port handling investments) the ports of Valparaiso and San Antonio. The potential to use rail from San Felipe to any of these three ports is additional option, to be evaluated further.
