a low cost, less polluting alternative to smelting


  • Hydrometallurgical process (acid leaching)
  • 90% recovery possible
  • Low temperature (90-120 C)
  • No use of high pressure


  • Base metal producers (Copper, Zinc, Cobalt, Lead and other metals including PGMs)

Commercial Application


ARV Leach technology would give the ability of small-mid cap base metal producers to capture more of the value chain (e.g., ability to produce and sell copper cathode as opposed to discounted concentrate)

  1. Est US$12bn p.a. loss of revenue
  2. Low Capex/low Opex alternative to traditional smelting
  3. Environmentally friendlier


Potential to significantly improve the economic viability of certain mining projects.
