Tambourah Metals Strikes High-Grade Gold at Tambourah King: What’s Next?

Tambourah King Drilling Advances Resource Understanding

Tambourah Metals Ltd (ASX, TMB) has announced significant high-grade gold assay results from its recent diamond drilling campaign at the Tambourah Gold Project, located in the Pilbara region of Western Australia. The standout intersection came from hole TBRD25001 at the Tambourah King prospect, delivering 1.31 metres at 38.4 grams per tonne (g/t) gold from a depth of 82.14 metres. This result confirms the presence of high-grade mineralisation within a quartz vein system approximately 75 metres below surface.

The drilling program, supported by a Western Australian government co-funding grant, comprised eight diamond drill holes totalling 785.4 metres. These holes were strategically designed to test beneath and along strike from historic gold workings at Tambourah King, Alexandria, and Young Australian prospects. All holes successfully reached their planned target depths, providing robust data for geological interpretation.

Expanding the Gold Footprint at Alexandria and Young Australian

Beyond Tambourah King, maiden diamond drilling at the Alexandria and Young Australian prospects has confirmed gold mineralisation in previously underexplored areas. At Alexandria, hole TBRD25027 intersected 0.2 metres at 23.6 g/t gold from 67.7 metres, while Young Australian’s TBRD25031 returned 0.32 metres at 5.1 g/t gold from 53 metres. These results validate the continuity of mineralised quartz lodes over significant strike lengths and highlight the potential for further resource expansion.

Tambourah’s Executive Chairperson, Rita Brooks, emphasised the significance of these findings, noting that the high-grade intersections at Tambourah King reinforce the prospect’s potential for an initial resource estimate. She also highlighted the company’s commitment to accelerating exploration activities across its portfolio of more than 20 gold prospects within the Tambourah Goldfield.

Next Steps, Infill Drilling and Resource Modelling

To build on these encouraging results, Tambourah Metals plans to undertake an infill reverse circulation (RC) drilling program of approximately 1,000 metres at Tambourah King. This program aims to close existing drill spacing gaps to around 25 metres, enabling a more detailed understanding of grade distribution and mineralisation boundaries. Following the infill drilling, the company intends to commence geological modelling and prepare an initial resource estimate.

Further RC drilling is also planned to follow up on the promising first-pass results at Alexandria and Young Australian, with the goal of delineating the extent and grade continuity of the mineralised lodes. These efforts are part of Tambourah’s broader strategy to systematically explore and develop its Pilbara gold assets.

Exploration Context and Technical Assurance

The Tambourah Gold Project targets Archaean quartz lode-style gold mineralisation, a style known for its potential to host high-grade deposits. The recent drilling was conducted on granted tenements underpinned by heritage agreements with the Palyku People, ensuring responsible exploration practices. Sampling and assay procedures followed industry standards, with core samples processed by ALS Laboratories using fire assay methods considered total for gold.

While true widths of mineralisation are estimated at 50-60% of downhole lengths, the company acknowledges some uncertainties remain, particularly regarding coarse gold distribution and sample representativity. Nonetheless, the consistent geometry and strike extent of the mineralised shear zone at Tambourah King provide a solid foundation for resource development.
