Metallurgy

Oxide

The upper ~70 metres of the deposit are oxide. Column testwork on the oxide returned better than 85% in two weeks.
 

Gravity Testwork

More visible gold observed in the 2020-2024 programs than previous years. Recent testwork recovers between 42-45% by gravity alone.
 

Gravity +
Carbon-in-leach

Recoveries of up to 87.5% were obtained with an average of 77% recovery.
 

Additional studies underway aimed at increasing recovery to over 90% include the following methods with 40% recovery from gravity:

•  ALBION PROCESS™ OXIDATION-CIL: >93% recovery
•  POX-CIL: 92% gold recovery
•  BIOX®: 90% gold recovery
