Calidus Resources has announced the discovery of a lithium pegmatite extending over 1km in strike length at Spear Hill in East Pilbara, Western Australia.
The Spear Hill area, about 50km SW of Marble Bar, is part of the historic Shaw River tin field which lies almost entirely within granitic rocks of the Shaw River batholith.
The discovery was made by Calidus’ 50% owned Pirra Lithium, a joint venture between Calidus and Haoma Mining NL.
Calidus Resources acquired the 50% in the new Pilbara lithium exploration company in January 2022.
According to the ASX announcement, Calidus is now undertaking further geological mapping to identify and confirm other pegmatites in the area and is planning to execute an initial 2,500m RC drilling program to test the thickness and down-dip extent of the pegmatite.
“It is already clear that we are in the early stages of an exciting lithium discovery with both scale and strong grades. There is a compelling business case to accelerate exploration now we have confirmed lithium grades for this significant outcropping pegmatite,” said Calidus Managing Director Dave Reeves.
“Despite the pegmatite being located close to the Hillside – Marble Bar Road, there is no record of geological mapping or sampling in the area and the area has never been drilled.
“These results highlight the immense prospectivity of the large tenement package and rights owned by Pirra Lithium.”
