Musgrave Minerals Encounters New Gold at Cue
THE DRILL SERGEANT: Musgrave Minerals (ASX: MGV) announced hitting more gold via drilling of 56 aircore/reverse circulation (RC) drill holes on the company’s 100 per cent-owned ground at the Cue gold project in Western Australia.
Musgrave Minerals’ latest round of drilling is testing new Starlight analogue targets on trend from the high-grade Starlight gold discovery at the Break of Day deposit.
The regional drilling program targeting Starlight analogues at Cue intersected high-grade gold at Target 9 – also known as Leviticus, 1.8km south of Break of Day.
A single north-south aircore/RC traverse across the Leviticus target intersected two separate zones of high-grade, near-surface gold mineralisation.
Results include:
20MUAC058
4 metres at 13.1 grams per tonne gold from 1m, including 3m at 17.3g/t gold from 1m; and
20MUAC058
2m at 10.3g/t gold from 33m.
To date 20 traverses have been completed with assays received for 12 traverses and anomalous gold intersected at 10 of the targets, including high grade, near surface intersections at Target 9 (Leviticus) and Target 2.
Leviticus hosts an existing inferred resource of 42,000 tonnes at 6g/t gold for 8,000 ounces of gold.
“Positive results from the regional drilling program continue to highlight the upside gold potential following a re-interpretation of the gold lode geometries within the Break of Day shear corridor,” Musgrave Minerals managing director Rob Waugh said in the company’s announcement to the Australian Securities Exchange.
“Regional target drilling is continuing to test targets, and follow-up of the high-grade results at Target 2 is underway with Leviticus follow-up to follow.”
Musgrave Minerals also completed initial metallurgical test work on the Starlight gold lode at Break of Day, on the company’s wholly-owned ground at the Cue project in the Murchison region of Western Australia.
Musgrave Minerals described the results as being “exceptional” with testwork highlighting gravity and cyanide leach recoveries averaging 98 to 99 per cent across the different domains (oxide, transitional and fresh).
The testwork also highlighted the amenability to conventional gravity and leaching techniques using standard reagents.
Metallurgical recovery tests were completed on the four samples (oxide, transitional and 2 x fresh composites) at various grind sizes across the strike and depth extent of the Starlight lode.
The gravity recoverable component was initially concentrated using a conventional laboratory scale bench top Knelson concentrator, followed by amalgamation and intensive cyanide leaching of the concentrate.
A conventional 48hr cyanide leach was then carried out on reground (P80 75µm) residual material from the Knelson concentrator with readings taken periodically to determine leach kinetics of the samples.
The test work demonstrated very rapid leaching kinetics for all four samples and overall recovery of between 98.8 per cent and 99.5 per cent over short leach times.
“This is a fantastic result at Starlight – Break of Day,” Musgrave Minerals managing director Rob Waugh said in the company’s announcement to the Australian Securities Exchange.
“The very high total gold recovery and high gravity-only component recovery ensures that conventional processing options can be applied in any development scenario and also means the mineralisation is suitable for treatment through several of the nearby processing facilities currently in operation.”
