Pioneer Resources pumps up lithium portfolio

THE DRILL SERGEANT: Pioneer Resources (ASX: PIO) has added to its recent lithium acquisitions by entering into an Option Agreement to acquire a 90 per cent interest in the Donnelly lithium project, located in the Greenbushes Mineral Field, in south-west Western Australia.

The Donnelly project extends from 12km to 60km southwest of the world-class Greenbushes lithium mine, and comprises two exploration licence applications (E70/4826 and E70/4829) covering a total area of approximately 220 square kilometres.

Pioneer considers the Donnelly project to be prospective for lithium contained in spodumene-bearing pegmatites of the Lithium-Caesium-Tantalum (LCT) geochemical family.

The company explained this type of pegmatite hosts the Greenbushes mine, and is similar to that intersected in drilling at its recently acquired Mavis lithium Joint Venture project in Canada, and targeted at the 100 per cent-owned Phillips River lithium project in the Great Southern region of WA.

“Lithium and other elements associated with LCT pegmatites are evident as anomalies in sampling undertaken by the Geological Survey of Western Australia,” Pioneer Resources said in its ASX announcement.

“To date no follow up exploration has been completed.

“Most of the project is covered with laterite – which is known to degrade and mask pegmatites, however laterite is an excellent geochemistry sampling medium and has been proven very effective by CSIRO to locate LCT-style mineralisation in the Greenbushes district.”

The Donelly project is readily accessible through a network of main, regional roads and forestry tracks for access, and water, power, while the Port of Bunbury is approximately 120km away.

Pioneer indicated its initial evaluation will comprise reasonably detailed, non-ground-disturbing surface sampling of laterite along forestry tracks, for a suite of elements including lithium, and other pathfinder elements.
