Minerals explorer buys Thunderdome project

Minerals exploration and development company Rumble Resources has expanded its footprint in Australia’s Fraser Range province by acquiring the Thunderdome project for a cash payment of A$60 000.

The company said last month that the new 100% Rumble-owned project and exploration licences expand Rumble’s Fraser Range footprint to 3 590 km2. Rumble now owns a 100% interest in 16 of the 17 Fraser Range tenements.

The Thunderdome project was a strategic low-cost acquisition, which will enable the company to use its cash for high-impact exploration.

The project covers 140 km2 in the main Fraser Range gravity ridge associated with dense mafic/ultramafic rocks of the Fraser Range.

The project is adjacent to the Rockford project acquired by ASX-listed exploration company Legend Mining from minerals exploration services provider Creasy Group, as announced on July 2.

The Thunderdome project has a large prominent dome feature clearly visible on regional airborne magnetic images. This large dome feature is one of the largest in the Fraser Range and has a fold axis of some 22 km. Within this larger target area are also several smaller features, which may represent later stage intrusions.

Previous exploration for nickel and copper on the project site was recently carried out by Creasy Group company Ponton Minerals.

This regional exploration comprised reconnaissance air core drilling on a 5 km × 15 km spacing with two holes within the current project area.

One of the historic air core drill holes, PNAC036, was highly anomalous in copper and zinc, and returned an intersection of 6 m at a copper content of 0.11% and a zinc content of 0.28% from 51 m. This intersection was within a carbonaceous unit, which is part of the cover sequence.

Work completed to date included a recent 100-m-spaced airborne magnetic survey, reprocessing of regional gravity data and petrology on end-of-hole rock chips from PNAC036.

Applications of the E28/2527, E28/2528 and E28/2529 tenements cover 160 km2 in the Fraser Range. There are portions of these tenements that are subject to competing tenement applications and Rumble has lodged objections to grant, which is scheduled for Kalgoorlie Warden’s Court, in Western Australia. These applications abut ASX-listed mineral resources exploration and development company Buxton Resources’ prospective Zanthus project that is currently reverse-circulation drill testing two high priority conductors on the project.

Previous drilling by Buxton identified three separate zones of finely disseminated, magmatic nickel-copper sulphides at the Zanthus project. The presence of magmatic nickel sulphides within mafic to ultramafic intrusive rocks indicates that the project is highly fertile and prospective for the discovery of nickel-copper sulphide mineralisation.

Application E28/2523 covers 206 km2 in the Northern Foreland of the Albany-Fraser Range. This has been interpreted to host similar intrusive features to that being explored by ASX-listed mining company Windward Resources’ at the Uraryie and Uraryie South prospects.

Drilling of the Urayie prospect last December returned anomalous nickel assays up to 0.55%. Initial drilling of the Uraryie South Intrusive complex is planned for the second quarter of the 2016 financial year following completion of a heritage survey.

Rumble will continue to evaluate Fraser Range projects to provide its shareholders with multiple opportunities to make the next significant nickel discovery in the Fraser Range.

Rumble’s technical team will continue to review the outcome of the company’s recent drilling programme at the Zanthus project. Rumble will assess the results of the down-hole electromagnetic, ground electromagnetic programmes, assays and petrology as it comes to hand, to help determine with the next phase of exploration.

Rumble is fully funded to advance preparations for the next stage of exploration at its other Fraser Range projects including Big Red and the Thunderdome project.

At the recently acquired Thunderdome, part of the preparations will include analysing the high-quality aeromagnetic data, gravity and geochemical data sets. Once this has been completed, a comprehensive exploration programme will be put together, which will include targeted geophysics and follow-up drill programmes.
