EL9330 Black Range
(Low Sulphidation Epithermal (Au, As, Pb and Zn)
The Black Range Project is in the Central Lachlan Fold Belt, NSW, which hosts world-class copper-gold orebodies including the Cadia-Ridgeway, North Parkes and Cowal Mines. Black Range provides Legacy district scale control of 100% of the known epithermal style mineralisation within the Mountain Creek Volcanics covered by a 905km2 licence and licence application.
The Black Range Project (EL9466/ELA6613) covers 905km2 of volcanics prospective for low sulphidation epithermals. It is located 65km from Legacy Minerals’ Bauloora Project (Newmont Joint Venture).
No significant exploration has been carried out on the project since 1992. Over 30km of underexplored strike between known epithermal occurrences including the high priority targets of Sugarbag Hill Prospect and Mylora Prospect.
Black Range is a late Devonian, early Silurian volcanic system dominated by acid volcanics. Rhyolite to dacitic volcanism with lavas, breccias and tuffs are widely distributed and associated with epithermal mineralisation. A 5.2 sq. km zone of silica-sericite-pyrite alteration has been mapped with low-sulphidation gold mineralisation intercepted in historical shallow percussion and diamond drilling. The interpreted low temperature quartz and low-iron sphalerite that is associated with gold mineralisation indicates the Projects may host a large, preserved epithermal environment.
Legacy Minerals will progressively develop the Black Range Project through systematic exploration work including data compilation and reprocessing, geological mapping, rock chip sampling and petrography before assessing the benefits of conducting further geophysical or geochemical surveys including drill campaigns.
