Breaker Resources NL (ASX:BRB) has made a high-grade lithium discovery at its Lake Roe Gold Project in Western Australia, following a 1,503 metre reconnaissance reverse circulation (RC) drill program.
Five wide-spaced RC drill holes have all intersected significant widths of high-grade lithium mineralisation including:
• 17 metres at 1.80% lithium oxide from 36 metres;
• 14 metres at 1.03% lithium oxide from 92metres; and
• 9 metres at 1.60% lithium oxide from 97 metres.
The drill holes reported are the first drill holes of any kind to test the 3.4 x 1 kilometre lithium-bearing pegmatite zone at the Manna discovery.
Manna is located 15 kilometres south-southwest of Breaker’s 1.1 million gold ounces Bombora Gold Deposit.
Breaker drilling at Manna indicates a 150-200 metre-wide swarm of spodumene-rich dykes extending over a distance of at least 700 metres, with individual pegmatite dykes up to 15 metres in width.
Notably, the mineralised pegmatite encountered in the drilling can generally be linked to mineralised pegmatite observed at surface, suggesting good continuity in the dip dimension.
Further steps are planned to gauge the size and economic potential of the discovery to assist in formulating an appropriate strategy for monetising it in a way that yields the maximum benefit to Breaker’s core focus on gold.
A multi-element auger surface geochemistry program is underway over a 90 square kilometres area that will simultaneously assess the potential for gold, lithium and other pegmatite-related metals including tantalum, tin, niobium, cesium and rubidium.
A short program of diamond drilling is also planned to obtain samples for preliminary mineralogy and metallurgical studies and to confirm the pegmatite orientations.
