Cobre is currently pursuing two base metal exploration projects, Perrinvale and Sandiman, which both represent under-explored areas within the low-risk mining jurisdiction of Western Australia.
With early confirmation of Volcanic-Hosted Massive Sulphide (VHMS) mineralisation at the Perrinvale Project. Cobre has now moved to 100% ownership of this asset.
Recent drilling at the Schwabe Prospect at Perrinvale has identified massive sulphide mineralisation at shallow depth, including 6m grading 8.93% copper, 3.1 g/t gold, 3.52% zinc, 30 g/t silver and 0.14% cobalt. Cobre is now focussed on follow-up exploration at Perrinvale to unlock the VHMS potential of the area.
The Perrinvale VHMS Project was the Company’s first and most advanced project with near surface high-grade copper and zinc-rich Volcanic Hosted Massive Sulphide (VHMS) mineralisation confirmed by drilling.
The Sandiman tenement is judiciously selected on the complex boundary of two major tectonic units of Western Australia – the Proterozoic Gascoyne Province to the east, and the Palaeozoic Carnarvon Basin to the west.

Base metal potential in the Lake Barlee area was first recognised in the early 1970s, but appears to have been overlooked by subsequent explorers. At that time, ground magnetics and early IP technology were the geophysical tools applied.
Today, EM survey technology is considered the primary geophysical tool used for VHMS exploration. In conjunction with our consultant Newexco, a first pass ground EM survey was completed in March 2019 over parts of the project area thought to be favourable for VHMS. This analysis identified 8 widely-spaced conductors up to 3km long which could be associated with VHMS mineralisation.
