Tambourah Metals (ASX: TMB) has completed a new reverse circulation (RC) drilling program at the Tambourah King lode system as it continues an aggressive examination of its Tambourah gold project in Western Australia’s Pilbara region.
The company’s latest drilling tested a section below a hole it diamond drilled in 2024 that indicated good potential for the definition of high-grade gold mineralisation.
The 2024 diamond hole hit 2.65 metres at 32.3 grams per tonne gold from 58.35m, including 1.05m at 77.4g/t gold from 59.05m.
Testing King lode
Tambourah commenced this latest RC drilling program at the King lode system in early March 2025 with the secondary aim of in-filling the existing drill coverage along strike.
To date, the company has traced approximately 300m of the system.
11 holes have successfully intersected the quartz lode structure.
WA government support
The company is using a WA government co-funded drilling grant of up to $180,000 to support the Tambourah King campaign.
The drilling program has initially focused on the Tambourah King and Western Chief lodes and is still to test multiple workings at the site.
Tambourah now plans to expand the drilling coverage at the project to test areas it believes have previously been ineffectively explored.
Sizeable gold strike
The Tambourah goldfield extends over 3 kilometres and comprises a series of sub-parallel, northerly striking, steeply dipping quartz lodes, often within a wider halo of carbonate alteration.
The field has historic production of 5,445 tonnes for 148 kilograms of gold, equating to a 27.35 grams per tonne gold head grade.
The company is looking to extend the areas of known gold mineralisation at Tambourah, both along strike and beneath shallow workings, with its ongoing drilling campaigns.
