Melbourne-based Orion Minerals is nearing completion of its Prieska zinc-copper drill-out program and has now commenced near-mine exploration in South Africa.

The Prieska project is 270 kilometres south-west of Kimberley in the Northern Cape province.

Since May last year, 94 intersections — including 39 mother holes and 55 deflections — have been completed on the deep sulphide target of the Prieska project.

Orion managing director Errol Smart said, “With us now nearing the completion of the Prieska deeps drill-out, having drilled over 83,000 metres in 15 months, we are very pleased to move on to the exploration for satellite deposits to the exceptional Prieska volcanogenic massive sulfide (VMS) ore deposit. These large VMS bodies are known for their propensity of occurring in clusters.

“Prieska is one of the largest known VMS deposits and the surrounding area has not benefitted from any modern exploration for more than 35 years.”

Prieska houses one of the world’s top 30 VMS deposits, and is the largest of four South African exploration projects being advanced by Orion as of June 2018.

Orion aims to update Prieska mineral resource estimate, including upgrade in resource categories, by the fourth quarter (Q4) of this year. Eight diamond drill rigs remain deployed for infill drilling to increase sample density in the deep sulphide mineral resource.

Almost 2500 metres of diamond drilling will be completed before the update of Prieska mineral resource estimate. Orion anticipates drilling to conclude mid-October this year.
