Tambourah Metals (ASX: TMB) has announced promising results from its initial exploration program at the Speewah Nth project in Western Australia, revealing high-grade antimony, silver, and copper assays from collected rock samples. Tambourah Metals is focused on exploring critical metals and energy resources. The company currently has tenements in the Pilbara, the Northeast Goldfields and the Southeast Goldfields regions of Western Australia.
A total of 35 rock samples, comprising quartz vein and gossanous material, were collected from outcrop and float within the 6-kilometre-long Chapman–Catto’s trend. Seven of these samples showed significant copper concentrations, ranging from approximately 0.1% to a maximum of 3.12%, accompanied by silver levels up to 512 parts per million and antimony grades reaching 4.54%.
These results confirm historical findings from surface programs at the Chapman–Catto’s corridor, which had previously focused on copper and gold exploration. The program represents Tambourah’s first exploration activity at Speewah Nth, an area of 181 square kilometres in the northern half of the Speewah Dome. Given the recent surge in antimony prices, from US$12,000 per tonne to US$60,000 per tonne, Tambourah has prioritised antimony as its primary exploration target at Speewah Nth.
The company plans to conduct follow-up outcrop mapping and sampling along the eastern margin of the Speewah Dome to pinpoint additional antimony-silver prospects, paving the way for future drilling operations. The Speewah Nth tenement is situated 4km from Tivan’s (ASX: TVN) Speewah Fluorite deposit. Executive chair Rita Brooks stated the company has identified untested antimony-silver targets and these will be incorporated into the exploration program as the company advances towards drilling.
