Rumble Secures 100% Ownership of Thunderstorm Gold Project with High-Grade Hits

Full Control Secured Over Thunderstorm Gold Project

Rumble Resources Limited has officially completed the acquisition of the remaining 70% interest in three key exploration tenements within the Fraser Range Province from IGO Limited. This move grants Rumble 100% ownership of the Thunderstorm Gold Project, a strategically located asset in Western Australia's Albany-Fraser Range region. The transaction was settled through the issuance of nearly 8.8 million Rumble shares valued at $300,000, with IGO retaining a modest 1.05% Net Smelter Return royalty on any future mineral production.

Promising High-Grade Gold Discoveries at Gazelle and Pion

The Thunderstorm Project encompasses six granted exploration licenses and two applications, covering a substantial 601 square kilometres. Notably, the project hosts the Gazelle and Pion gold prospects, where previous wide-spaced drilling has revealed encouraging high-grade gold mineralisation. Highlights include intersections such as 16 metres at 6.69 grams per tonne gold from 42 metres depth at Gazelle, and 6 metres at 9.15 grams per tonne gold from 48 metres. The Pion prospect also showed consistent gold anomalism across six consecutive drill holes, with a standout intercept of 4 metres at 3.80 grams per tonne.

Geological Potential and Exploration Outlook

Geological studies suggest the gold mineralisation style at Thunderstorm is complex, involving both palaeochannel (ancient river systems) and primary basement gold deposits. Advanced microscopic analysis indicates multiple gold grain types, pointing to a dynamic mineralisation process involving alluvial transport and chemical regrowth. This dual potential enhances the project's attractiveness as it could host both near-surface and deeper gold resources.

Next Steps, Drilling and Heritage Surveys

Rumble plans to initiate a significant ~5000-metre Aircore and Slimline Reverse Circulation drilling program in the first half of 2026. This campaign aims to better define and extend the mineralisation at Gazelle and Pion, targeting the palaeochannel systems and basement sources. Prior to drilling, a heritage survey will be conducted to ensure compliance and community engagement. Managing Director Peter Harold expressed optimism about the project’s potential and the upcoming exploration activities, highlighting the team’s eagerness to unlock further value.

Strategic Implications for Rumble Resources

By consolidating full ownership of the Thunderstorm Gold Project, Rumble strengthens its foothold in a highly prospective gold province adjacent to significant regional infrastructure and known deposits. This acquisition complements Rumble’s broader portfolio, which includes other promising projects like Western Queen and Earaheedy. The move signals Rumble’s commitment to advancing its gold exploration strategy in Western Australia, positioning the company for potential resource growth and value creation in the near term.
