Gold rush at Klondyke for Calidus

Pilbara gold has gone from strength to strength after Calidus Resources announced exceptional recoveries at its emerging Warrawoona project.
Testing showed 63 per cent of gold at the Klondyke deposit was recoverable by using gravity alone, while the total gold recovered was 96 per cent through conventional cyanide leaching. The Klondyke deposit forms part of the Warrawoona Gold Belt, 25km south-east of Marble Bar.
The results support the inclusion of a gravity circuit into the processing plant and support the expectation the project will yield between 40 and 60 per cent of the total gold content via the gravity circuit alone.
Calidus managing director Dave Reeves said the organisation was pleased with initial results of the metallurgical testing.
“These metallurgical results position Calidus very favourably as we progress towards the commencement of the pre-feasibility study to evaluate the development options for the Klondyke project,” he said.
“Attractive resource grade, geometry well suited to open-pit mining and simple ore processing with high gold recoveries and low reagent consumption could underpin Klondyke as a low operating cost mine in Western Australia.”
The gold recoveries came from samples from three diamond drill holes that covered 1.2km of the Klondyke resource representing both oxide and fresh ore.
According to Calidus Resources, the fresh samples gave a higher proportion of gold than the oxide sample.
The exceptional recoveries follow an announcement of 45 high-priority gold targets at Warrawoona and the acquisition of another 100sqkm in the area.
