Bradda Head Lithium Limited (AIM:BHL, OTCQB:BHLIF, TSX-V:BHLI)'s latest two drill holes of the Basin East Extension (BEE) 2023 drill programme in Arizona have returned the highest single interval grade so far, said the junior.

An intersection of 2,791 parts per million (ppm) lithium (Li) over 0.4 metres (m) and a separate sample of 641ppm molybdenum (Mo) over 1.22m was recorded within sections over 900ppm at widths of more than 75m in both holes.

Drilling at BEE has now finished with Bradda Head working on an upgraded mineral resource estimate (MRE) scheduled for mid-September.

As with earlier drilling during the programme, thicknesses of clay were better than expected, it added, confirming that lithium-bearing clays continue and appear to thicken to the north into the company's Basin North (BN) claims and likely west into Basin West (BW) claims.

Charles FitzRoy, chief executive, commented: “These latest assays solidify the resource expansion potential at Basin and the high-grade lithium intercepts encountered demonstrate the exceptional potential of the project.

"The company has now kicked off its Phase 3 drill programme at its 31sg km San Domingo pegmatite district in Arizona, with the main aim to delineate a resource," he added.
