Tambourah Metals (ASX: TMB) has continued its recent drilling success in Western Australia’s Pilbara region with promising hits from its Tambourah gold project.

The company has confirmed high-grade gold mineralisation in assays returned from its diamond drilling (DD) program at the Federal and World’s Fair prospects within the historic Tambourah project.

The successes at Federal and World’s Fair follow the recent discovery of new gold zones at the Tambourah King area.

Drill tests planned

The company told shareholders the gold mineralisation is likely associated with the eastern contact between the granite intrusion and the Apex Basalt.

It plans to further investigate this theory in future drilling campaigns.

The DD at World’s Fair followed up high-grade intercepts from a 2023 reverse circulation (RC) drilling program that returned shallow intercepts of 3 metres at 3.3 grams per tonne gold from 23m including 1m at 8.4g/t from 23m and 4m at 1.8g/t gold including 1m at 5.31g/t from 48m.

Depth extensions

For the first time, gold has been intersected at depth at the sparsely drilled Federal line of historic gold workings.

A single DD hole completed at the Federal prospect targeted depth extensions to the known mineralisation and was designed to determine the structural controls of the mineralisation.

The hole was drilled 100m south along strike from a previous Tambourah RC drill hole that reported 1m at 1.2g/t gold from 11m and 1m at 5.31g/t from 50m.

Tambourah King follow-up

Elsewhere, the company is planning follow-up drilling with 12 RC and DD holes south of Tambourah King to test the continuity of high-grade gold beneath historic pits along an additional 1,200m of strike where shallow drill intercepts were recorded at the Alexandria prospect.

The proposed program is designed to test for structurally-controlled gold mineralisation underneath the historic workings.

The work is co-funded by an Exploration Incentive Scheme grant of up to $180,000.
