NEWS: Big improvements in metallurgical performance
The Board of SolGold (LSE & TSX code: SOLG) is pleased to announce significant improvements in copper and gold recoveries from metallurgical testing at Alpala.
Improved recoveries in metallurgical tests across all valuable minerals indicates a major value uplift for Alpala.
The current metallurgical test programme has expanded on that conducted during the PEA and has produced substantial improvements in copper, gold and silver recovery and in copper concentrate grade. These results are supported by both locked cycle and leach diagnostic tests.
These results include:
An estimated 3.8% increase in copper recovery to achieve a life of mine average of 93.4% recovery
An estimated 21.6% increase in gold recovery to achieve a life of mine average of 87.2% recovery
An estimated 28.3% increase in silver recovery to achieve a life of mine average of 87.6% recovery
An estimated 2.7% Cu increase in concentrate grade to achieve a life of mine average of 28.7% Cu, equating to a projected 9% decrease is transport and smelting charges per tonne of concentrate produced.
Ongoing large-scale tests will also evaluate CAPEX and OPEX changes to update economics
