Global Geoscience Makes Groundbreaking Discovery – Heap Leach Lithium-Boron Extraction at Rhyolite Ridge

Highlights:

  • In an industry first, Global Geoscience has successfully demonstrated heap leach processing of Rhyolite Ridge lithium-boron mineralisation by achieving:
    • Lithium and boron recoveries of 88-92%
    • Rapid leach times at ambient temperature with moderate acid consumption rates
  • Heap leach processing provides substantially lower operating and capital costs compared to other forms of acid-leach processing as grinding, flotation, filtration and leach tanks are not required
  • Global’s Rhyolite Ridge is the only lithium deposit in the world that has been demonstrated to be amenable to simple heap leach processing, reinforcing it as a credible alternative to spodumene and brine deposits as a major, low-cost and long-term source of lithium
  • Further metallurgy and mining studies are in progress, with engineering studies about to commence.  All are part of the Company’s Rhyolite Ridge Pre-Feasibility Study (PFS)
