Tungsten Discovery at Western Queen Could Shift Project Economics Significantly

Strong Gold Results Extend Mineralisation

Rumble Resources Limited has announced encouraging results from its latest diamond drilling campaign at the Western Queen Project in Western Australia. The drilling has successfully extended gold mineralisation down plunge at the Western Queen South deposit, with standout intercepts including 6.93 metres grading 4.10 grams per tonne gold from 362 metres depth and a high-grade 0.3 metres at 32.38 grams per tonne gold from 300.3 metres.

These results reinforce the continuity of the gold system and suggest potential for further resource growth. The mineralised zones are characterised by silicification and sulphide alteration, consistent with the known orogenic gold style at the project. Importantly, the gold mineralisation remains open at depth and along strike, inviting further exploration.

Tungsten Discovery Adds New Dimension

Alongside gold, the drilling has intersected significant tungsten mineralisation in the form of scheelite-bearing skarns at both Western Queen South and the nearby Princess deposit. Assays have returned impressive grades, including a 0.4-metre interval at 10.53% tungsten trioxide (WO3) and multiple other high-grade zones.

Petrographic studies confirm that the tungsten mineralisation represents an early prograde endoskarn event that predates the gold mineralisation. This geological relationship opens the possibility of mining tungsten as a co-product with gold, potentially enhancing the project's revenue profile.

Path to Maiden Tungsten Resource and Metallurgical Testing

Rumble is progressing with a maiden tungsten Mineral Resource Estimate, expected to be completed during the September quarter. Historical diamond core sampling for tungsten is underway, with assay results anticipated soon. Preliminary metallurgical testwork has been promising, indicating that tungsten-bearing material could generate a significant revenue stream when mined concurrently with gold.

The company is preparing bulk samples for advanced metallurgical testing to refine recovery rates and optimise processing. These efforts aim to integrate tungsten into the mine schedule, potentially improving the economics of the Western Queen South open pit operation.

Strategic Outlook and Exploration Potential

Rumble Resources holds 100% equity in the Western Queen Project, which is strategically located near several gold processing plants. The project has a history of high-grade gold production and now shows strong potential for tungsten as a valuable by-product.

With gold mineralisation open at depth and along strike, and tungsten mineralisation open in all directions, the company plans further drilling to extend resources. Mining studies for both open pit and underground scenarios are underway, aiming to unlock near-term cash flow and long-term growth.
