  • To optimize output, ongoing system updates and adjustments are expected over the next few months, including iron separation testing and production, expected to be completed in 6 weeks.

  • Five-thousand tonnes of copper-gold-iron material will be processed per month and is expected to produce 300 tonnes of copper/gold concentrate and 1,800 tonnes of iron concentrate.

  • Final tails will be "dry stacked" in a tailings compound where the Company is reviewing opportunities to sell this product to the agricultural/construction industries based on contained phosphorus. Final tails are expected to contain approximately 25% apatite.

  • First copper concentrate sales are expected in late-August, supported by the concentrate purchase and sale offtake agreement.

El Peñón

The El Peñón processing facility is a state-of-the-art Environmental Social Governance (ESG) focused operation designed to reduce transportation and processing costs. The plant utilizes nonchemical flotation and magnetic separation to generate copper/gold and magnetic iron concentrates as income streams. A dry stack tailings process generates dry tailings without the requirement of a conventional tailings dam and reduces water consumption through recycling by 75%.
