Dart Mining NL (ASX:DTM) has started drilling copper-gold mineralisation targets at the wholly-owned Granite Flat project in northeast Victoria.
The company has started with percussion drilling to test the extent of copper-gold mineralisation at Granite Flat.
Up to 24 low impact sites have been determined to target bulk-tonnage copper-gold mineralisation.
Previous explorers have identified a broad area of gold and copper mineralisation and the company’s initial focus is to verify and extend previously identified mineralisation.
This mineralisation remains open at depth and along strike from the previous drilling.
Drilling program
Drill Australia Ltd has been contracted to test the strike extent of known copper-gold mineralisation at Granite Flat.
Rotary Air Blast (RAB) percussion drilling started in early November with the first phase assessment of targets set to conclude in mid-December.
Silica-sulphide mineralisation containing abundant sphalerite and common chalcocite, with rare to occasional chalcopyrite has been intersected in the first drill holes.
The company is experiencing a delay in preliminary assay results due to the current boom in minerals exploration.
Comprehensive program for 2021
Previous explorers in the area have constructed a notable network of tracks and drill pads, providing ample worksites available to Dart Mining across several mineralisation targets.
In tandem with drilling, Dart is undertaking a regional sampling and geological mapping program to further assess the wider potential of Granite Flat.
Data obtained from the shallow exploration drilling program will be used to inform plans for a comprehensive, targeted reverse circulation (RC) and diamond drilling program in 2021.
Granite Flat
Granite Flat is adjacent to the Omeo Highway between Mitta Mitta and Glen Wills, about 74 kilometres southeast of Albury-Wodonga and 360 kilometres northeast of Melbourne.
The Granite Flat area has an orogenic mineralisation overprint along with northwest-oriented shears, making the area highly prospective for orogenic gold, as well as other precious and base metals.
Given the polyphase nature of the Banimboola Quartz Monzodiorite and the extensive gold and copper soil anomalism, the company believes that the Empress Tenement within the project has prime potential to host porphyry-style gold-copper mineralisation.
