Future Battery Minerals (ASX:FBM) has uncovered new pegmatites during phase-four reverse circulation drilling at the northern end of its Kangaroo Hills Lithium Project in Western Australia.
Dubbed the ‘Potoroo’ discovery, it has extended the overall mineralised footprint of the Kangaroo Hills Project to roughly 900m of strike, which also includes the Big Red, Big Red Extension, and Rocky targets.
The drilling results from Potoroo will be used as proxies in delineating the thicker high-grade core of pegmatite in the region.
Managing Director and CEO Nick Rathjen says the newly discovered pegmatites not only extend the overall footprint of the project, but clearly represent further potential at Kangaroo Hills.
“The north-east extension of Big Red is set to be tested with the Phase 4B program, commencing in the coming weeks,” he says.
The second part of the fourth phase will consist of 3,000m of reverse circulation drilling.
The latest drilling program comprised 15 holes for 2,630m, focused on testing the northern continuity of Big Red and other high-potential resistivity anomaly targets.
Future Battery says the results from the Big Red Extension demonstrates northern continuity of Big Red pegmatite, with the best results including 31m @ 1.13% lithium oxide from 86m, including 20m @ 1.43% lithium oxide from 88m.
Rathjen says drilling at the Big Red Extension has also uncovered faults that have altered the company’s interpretation of Big Red’s geometry to the north.
“We believe that the larger Big Red pegmatite (inclusive of Big Red Extension) remains open to the north-east, rather than to the north/north-west coincident with the resistivity feature in this area,” he says.
“The resistivity may be highlighting shallower pegmatites in addition to Big Red, such as the newly discovered Potoroo, which will be investigated further in future drill programs.”
The Kangaroo Hills Project lies in the Goldfields region of Western Australia and is considered prospective for hard rock lithium.
