Initial testwork demonstrates up to 99% gold recovery at McTavish East
Initial testwork has demonstrated recoveries of up to 99% at the McTavish East prospect within the Kookynie gold project in WA.
Carnavale Resources (ASX:CAV) completed initial leach test work over McTavish East with samples collected from aircore drilling completed in September 2022 and reverse circulation drilling completed in May 2023.
A total of 16 200-250gm ore grade samples were taken and leach tested for 24 hours. Samples were selected from both oxide and fresh rock material, with recoveries in the oxide totalling 99% and between 97% and 99% in the fresh rock.
Carnavale has planned further metallurgical testwork to boost these results with work including leach testwork and gravity separation techniques.
Chief executive Humphrey Hale called these results outstanding.
“The initial metallurgical results from McTavish East are outstanding, indicating the potential of excellent gold recoveries from traditional cyanide leaching processes,” he said.
“CAV is excited to continue the test work with further leach testing and the addition of gravity separation techniques to enhance the processing options and potentially reduce operating costs.”
McTavish East is a new discovery and has not been previously explored. It lies beneath a thin layer of cover consisting of transported material close to surface allowing for easy development.
Carnavale said these results give a good indication as to what can be expected from the oxidised and fresh rock areas of McTavish East.
