Confidential Project - Argentina

Project Highlights:

  • Due Diligence

Tierra Group was retained to perform metallurgical due diligence on two operating properties and two prospects in early stage development. The two existing operations consisted of a convention heap leach followed by ADR to produce a Dore on-site and a convention milling, CIL, ADR to produce Dore on-site. 

The two future opportunities consisted of an oxide resource with a proposed conventional milling, flotation, concentrate production flowsheet. The second was an underground resource with a complex carbonate/arsenic mineralization which requires a fairly complex flowsheet. This flowsheet was reviewed with site metallurgical staff and several challenges were identified which will require additional testing to confirm. Alternative solutions were offered and discussed, as well as recommended testwork.
