THE DRILL SERGEANT: Invictus Gold has commenced the maiden drill program at the Scartwater prospects located on the company’s 100 per cent-owned Drummond Basin project in Queensland.
The company will be conducting a program of 4,000 metres of reverse circulation (RC) drilling.
This will be carried out over the Scartwater prospects as well as the recently identified Whiteglow prospect.
“The Scartwater prospects, called West Porhyry and East Porphyry, were recognised in modest outcrops and in related anomalous gold-in-soil responses together with high-grade rock chip assays of up to 32 grams per tonne (one ounce per tonne),” Invictus Gold said in its ASX announcement.
According to Invictus, the rock chip assays it has received are associated with disseminated pyrite in altered porphyries.
The two porphyry bodies are each about 500m long and up to 300m wide.
“The East Porphyry is coincident with a magnetic anomaly and both porphyries are associated with elevated potassium responses in airborne geophysical data,” the company said.
“These geophysical and geochemical signatures are very similar to those at many porphyry-style deposits in Queensland, as at the Mount Wright and Mount Leyshon Mines about 100 kilometres to the north, and at the large Anthony porphyry-hosted molybdenum deposit about 100 kilometres to the south.”
The Whiteglow prospect is said to comprise a gold and silver-in-soil anomaly that measures 1,500m long and 500m wide.
At the northern end of the soil anomaly a rock chip sample from a mineralised and altered porphyritic rock returned an assay of:
– 7.3 grams per tonne gold and 200 grams per tonne silver.
Invictus indicated this northern area is close to three previous holes it has drilled which returned intercepts of:
– 34 m at 0.3 g/t gold from 24 m, 18 m at 23 g/t silver, and 0.6% lead from 26m.
The area tested by these previous drill holes lies outside the soil anomaly identified by Invictus, and that will be the focus of the company’s drill program.
