Project Development Program

The Company is currently advancing the Pre-Feasibility Study (PFS) for the Project.

The 2019 Preliminary Economic Assessment (PEA) showed that the Vizcachitas Project is a large copper deposit which can be exploited using conventional large scale open pit and concentrator technology with robust economics.

As part of the PEA three alternatives were evaluated for process plant throughputs namely, 55 ktpd, 110 ktpd and 200 ktpd, with the 110 ktpd case yielding the highest After-Tax IRR and shortest Payback Period.

Pre-Feasibility Study

Following the Company’s environmental guidelines and to ensure long term robust economics the PFS project design was tailored to ensure that the Project would:

  • Minimize water consumption
  • Minimize the project’s footprint
  • Minimize energy usage
  • Minimize dust emissions
  • Minimize impact on local communities
  • Facilitate daily commute of workforce to the project site
  • Ensure that the project is economically robust

Testwork as part of PEA and PFS identified the following technologies that among others will help meet these requirements.

  • High-Pressure Grinding Rolls (HPGR)
    • Reduce water consumption
    • Reduce energy consumption
    • Reduce dust emissions

For further information on HPGR

  • Dry-stacked tailings
    • Reduce water consumption by approximately 50% from thickened tailings
    • Reduce the Project’s footprint
    • Transport by trucks and/or conveyors
    • Eliminate the need for a dam wall

For further information on Dry Stacked Filtered Tailings

The combination of these technologies can reduce our water consumption by approximately 60-70% when compared to the PEA

The PFS is targeted for Q1 2023.

Note: The Preliminary Economic Assessment is considered preliminary in nature and 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 Preliminary Economic Assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
