Bradda Head Lithium Limited (AIM:BHL, OTCQB:BHLIF, TSX-V:BHLI) said initial results from core drilling at San Domingo in Arizona have identified new deeper zones of lithium-bearing pegmatite.

Assays from 14 holes received so far showed grades of up to 0.83% Li2O over 6.35 metres (m) and 1.03% Li2O from the best results.

Drilling in this programme was focused on the Midnight Owl, Bolt, and Lone Giant targets in the northern part of San Domingo and comprised 1,877m in 22 shallow core holes.

Previous drilling at Midnight Owl's had shown a best of 31.85m at 1.60% Li2O.

Drilling at Bolt detected anomalous tantalum in intervals coincident with the lithium intercepts, while tin was also identified.

Ian Stalker, executive chair, commented: “The elevated Ta (tantalum) and Sn (tin) levels show encouragingly strong comparisons to LCT-type [lithium-caesium-tantalum] systems, evidence of our robust lithium pegmatite district.

“Importantly, both Midnight Owl and Bolt targets continue to provide opportunities to expand on the lithium mineralisation, with the goal of defining near-surface resources.

"The initial batch of drill hole geochemistry provides us with an improved understanding of pegmatite characteristics and mineralogical zoning at San Domingo, particularly at the Midnight Owl and Bolt targets."
