Tambourah Metals Ltd (ASX:TMB) has announced the identification of seven initial epithermal vein-related antimony targets at its Speewah Nth project (E80/5889), located 110km southwest of Kununurra in the Kimberley region of Western Australia. Tambourah Metals is a West Australian exploration company established in 2020 to develop gold and critical mineral projects. The company is now prioritising these targets for upcoming reverse circulation (RC) drilling, pending statutory approvals.
Ongoing field programs focusing on the mafic-sediment contact along the eastern margin of the Speewah Dome have yielded strongly anomalous antimony, silver, and copper results. Recent outcrop search and sampling in the Catto and Haydens areas have confirmed the Cattos West prospect as a significant area of interest. Substantial surface mineralisation has been identified north of the Cattos West prospect, where no drilling has occurred to date.
The seven identified drill targets align with the mafic-sediment contact along the eastern margin of the Speewah Dome, including the historic Chapmans and Haydens prospects. Previous exploration indicated that this contact is an important control on polymetallic mineralisation (Cu-Ag-Pb-As±Sb) hosted in flat-lying or shallow-dipping vein sets.
Tambourah is planning initial testing of the discrete epithermal vein targets, which are potential hosts for significant silver, copper, and antimony mineralisation, with up to 1200m of RC drilling planned. The POW approval is currently pending. Additional sampling and outcrop searches in the Chapmans, Haydens and Haydens NW areas have been carried out, with samples en route to Perth for assay.
