All currency amounts herein are in US dollars unless otherwise indicated.

PEA Highlights

  • Total projected life of mine (“LOM”) production of approximately 1.74 million gold equivalent ounces averaging 155,500 ounces over the estimated 11 year life.
  • Projected LOM production of 1.29 million ounces of gold, 203.9 million pounds of copper and 2.98 million ounces of silver at recoveries of 91%, 80% and 64%, respectively.
  • After-tax Net Present Value (“NPV5%”) of approximately $279 million at base case commodity prices of $1,750 per ounce of gold, $21 per ounce of silver, and $3.50 per pound of copper; and approximately $442 million at spot commodity prices.
  • Total cash cost of $795 per ounce of gold and All-In Sustaining Cost (“AISC”) of $912 per ounce of gold (net of by-product credits).
  • Initial capital expenditures of approximately $425 million for a 15,000 tonne per day processing facility fed by a conventional truck and loader open pit mining operation with sustaining capital and mine closure expenditures of approximately $203 million.
  • After-tax IRR of 15.2% with a payback of 5.6 years.

1 Gold-equivalent grades were calculated using the following formula: AuEq = Au (g/t) + [Cu(%) x {Cu Price/Au Price} x 22.0462 x 31.1035] + [Ag (g/t) x {Ag Price/Au Price}].

2 Reported as AISC in the July 24, 2023 news release.

Compared to the PEA figures disclosed by the Company in the news release dated July 24, 2023, the results announced herein and in the Technical Report include minor corrections primarily to address the accounting of plant availability and clarifications on specific calculations.  For example, the total estimated mine life has been revised to 11.2 years from the previously announced 12.2 years as a result of an increase in annual throughput estimates to reflect nameplate capacity.

The PEA study results of La Mina are preliminary in nature and are intended to provide an initial assessment of the project’s economic potential and development options.  The PEA mine schedule and economic assessment includes numerous assumptions and is based on 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 project economic assessments described herein will be achieved or that the PEA results will be realized.

Readers should refer to the full text of the Technical Report, which is titled “NI 43-101 Technical Report and Preliminary Economic Assessment for the La Mina Project”, with an effective date of July 24, 2023 and is filed under the Company’s profile at www.sedarplus.ca.
