Carnavale Resources Ltd (ASX:CAV)’s exploration activities at the Ora Banda South Gold Project proceed apace, as it moves to drill the Carnage prospect.
The company’s first program of reverse circulation (RC) drilling at Carnage comes after it fielded some promising high-grade gold results following aircore drilling in the regolith.
Gold anomaly
This confirmed a gold anomaly with a strike length of 2.1 kilometres long within the Currawong sediment package along the Carnage shear.
The mineralisation is open to the northwest, south and southeast and the company believes it is orientated northwest along the Carnage Shear and modified to have a more north-south trend by the geology. Both trends are evident within the interpreted gold contours and geochemistry.
Previous significant results from the company’s aircore drilling at the prospect include:
- 4 metres at 30.20 g/t gold from 44 metres;
- 7 metres at 5.95 g/t from 80 metres (ending in mineralisation);
- 8 metres at 2.74 g/t from 48 metres;
- 4 metres at 2.69 g/t from 36 metres;
- 12 metres at 0.43 g/t from 44 metres; and
- 12 metres at 0.33 g/t from 40 metres.
The geology in the area is favourable to hosting a significant gold deposit, with major shear structures crosscutting a sedimentary basin with an identified felsic intrusion that correlates to a substantial regolith gold anomaly, identified by CAV during the aircore drilling.
Ignored by past explorers
CEO Humphrey Hale said: “Exciting times at Carnavale as we return to the Ora Banda Gold Project to drill test the substantial gold anomaly at the Carnage prospect with an RC rig.
“No previous RC drilling has been done at Carnage. Previous explorers ignored this area as the project area is covered by transported material overlying a sedimentary sequence.
“The excellent CAV aircore programs have defined a substantial gold anomaly with associated complementary geochemistry, a major shear and a newly mapped intrusion.”
Multi-element geochemistry
During its detailed exploration program, the company has collected detailed geochemistry along with the gold in the assay suite.
This multi-element geochemistry has demonstrated that the gold anomalism at Carnage is coincident with arsenic, tin, tungsten and bismuth, indicating a possible intrusive related source for the gold system.
The best gold anomalism identified in the saprock profile at the Carnage prospect is overlain by a significant gold anomaly in the transported material, interpreted to be derived from the local, primary bedrock gold source.
The prospect seems to have an analogous geological setting target to the +2.5-million-ounce at +4g/t Invincible Gold Mine, discovered by Gold Fields Limited near Kambalda in 2012.
