The Sandiman Project

Cobre has the right to earn up to 80% interest in the Sandiman Project, which consists of a single 202km² tenement held by private company GTTS Generations Pty Ltd. Accessible by road from Carnarvon to Gascoyne Junction, then 85km north along the Lyndon Road in an area subject to limited past exploration, Sandiman is a conceptual base-metals project.

Located in the Upper Gascoyne Shire on the eastern edge of the Southern Carnarvon Basin, 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.

Prospectivity of Sandiman is based on the cluster of barite veins in sedimentary basin rocks in a craton-margin geological setting. Barite has known association with Mississippi and VHMS base-metal deposits, along with mention of locally observed galena and sphalerite in historic exploration reports, gives the project area exciting exploration potential.

The deposit is situated on the complex boundary of two major tectonic units of Western Australia – the Proterozoic Gascoyne Province and the Palaeozoic Carnarvon Basin. The mineralisation comprises a series of Mississippi Valley Type (MVT) deposits that are hosted by Devonian aged Gneudna carbonate rocks.

A number of lithologies have been identified in these MVT deposits including the Barite Veining and Gneudna Formation Carbonate Rocks.
