Castle Minerals (ASX: CDT) has identified several areas of lithium and coincident indicator-element anomalism from an in-depth geochemical review of historical auger drilling data at its Woodcutters Lithium Project in Western Australia.
The company reports that the results delivered from the review are indicative of possible hard-rock lithium mineralisation associated with lithium-caesium-tantalum pegmatites.
The project’s close proximity to several mapped granite intrusions also provides additional encouragement that the discovery of a ‘reasonably sizeable’ pegmatite field may be possible.
Addressing the update, Castle Minerals Managing Director Stephen Stone said: “The lithium and coincident indicator elements anomalism identified within historical geochemical sampling data at the Woodcutters lithium project, the confirmed presence of pegmatites by the GSWA and their proximity to granite intrusives are all positives for the project and provide a solid platform for the next phase of exploration in a region where there are already well-established lithium deposits such as Bald Hill and Buldania.”
“[the results] are all positives for the project and provide a solid platform for the next phase of exploration in a region”
Data for the review was sourced from a gold-focused soil-auger program carried-out by AngloGold Ashanti in 2009 and 2010, with preliminary results revealing several discrete lithium anomalies supported by coincident elevated levels of rubidium, beryllium, caesium, and tin.
Castle has also undertaken a field orientation and reconnaissance site visit as a precursor to a proposed program of mapping and rock chip sampling of any outcropping pegmatites, focusing initially on the highest-priority targets generated by the review, and subject to grant of the licences.

The 242km² Woodcutters project lies along a distinctive structural trend that runs from the pegmatite field hosting the Bald Hill lithium-tantalum deposit, within Western Australia’s “Lithium Corridor”.
The Project area is also parallel to the trend that hosts Liontown Resources’ Buldania lithium deposit, and the Mineral Resources-owned Mt Marion operating mine.
