Today, the De Grey Mining Limited (ASX: DEG) share price is down 5.76% to $0.87, despite a positive announcement from the miner revealing high gold recoveries at its Hemi site.
What was in the announcement?
The announcement detailed positive metallurgical testing of the composites from two diamond drill holes at the company's Hemi site. De Grey used two processes to extract gold from the composites, one which used a conventional carbon in leach method and one which used a pressure oxidation method.
The processes were focused on the Brolga section of the company's Hemi site. The average grade of all samples at Brolga was 1.5 grams of gold per tonne.
The overall gold recovery from the two metallurgical processes combined was 96.3%, however, the company still has three additional composites which are still undergoing testing. The grade of the composite tested was 2.62 grams of gold per tonne.
Commenting on the result, De Grey managing director Glenn Jardine said:
The gold recovery achieved in the initial metallurgical testwork of oxide, transition and fresh mineralisation at Brolga is very encouraging. The testwork significantly de-risks the potential development of Hemi as a Tier 1 gold project in a Tier 1 jurisdiction. The testwork flowsheet used for Hemi can also be applied to De Grey's other regional resources in the Mallina Basin.
Hemi is a growing resource and contains a combination of oxide, transitional and fresh sulphide mineralisation. We will continue to increase our understanding of the scale and metallurgical properties of each of these domains across the deposit with ongoing testwork.
Jardine also highlighted that the company's Hemi mine location – which is situated 60 kilometres from Port Hedland and along major transport, gas and power corridors – is a major advantage for a Tier 1 gold resource project.
