Rumble and CSIRO to explore alteration zone in the Pilbara

By Justin Ware. Published at May 21, 2018, in Mining

Rumble Resources (ASX:RTR) has partnered with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), to investigate alteration mineral footprints at RTR’s Braeside Project, which is located in the Pilbara region of Western Australia.

With the CSIRO having expertise in mineral exploration interpretation, the duo will undertake a research program geared towards the wide pervasive alteration zones associated with base metal alteration on site.

At the same time, it’s worth noting that this is an early stage play and investors should seek professional financial advice if considering this company for their portfolio.

The collaboration will see the CSIRO aid in defining alteration signatures associated with base metal mineralisation. Importantly, previously completed drill hole spectral studies by RTR have confirmed widespread mineralisation at Braeside.

The company has received a $50,000 grant via the Australian Government’s Innovation Connection program, which is to be matched by RTR’s own funds. These funds will facilitate the commencement of the project.

RTR Technical Director Brett Keillor commented on the announcement, “Rumble has over 1000km2 of prospective tenure, much of it exposed and suitable for spectral mineral mapping. CSIRO is the premiere organisation in Australia with respect to the application of spectral research to exploration.

“The collaborative study with CSIRO will gain an understanding of the mineral alteration and mineralisation relationship that may lead to significantly expediting generation of high order targets for further geochemistry and possible drill testing.”

Previous exploration by RTR, including detailed surface geochemistry, prospect geological mapping and first pass RC drilling, has highlighted a strong association of base metal mineralisation with wide zones of pervasive silica-sericite-chlorite alteration.

The base metal mineralisation extends over a 34km strike within E45/2032 and is completely open. The mineralisation is associated with several altered structures which include the historic High Grade Ragged Hills Mine located at the southern end of the prospective zone.

Within the E45/2032 tenement are 11 instances of significant base metal in soil, with only four of these having been partly tested with the latest reconnaissance RC drilling, which identified a new high-grade zinc discovery at Devons Cut in the maiden drill program (below).

CSIRO will support RTR in their exploration R&D efforts as part of an Innovation Connections project.

The study by CSIRO will include:

  • Collection and evaluation of public (ASTER) and commercially (WorldView-3) available multispectral spaceborne data which will map:

- Background alteration

- Major geological units

- Alteration assemblages potentially associated with base metal mineralisation

- Dominant structures with additional aeromagnetic data

The study objectives are to:

  • Evaluate multispectral remote sensing imagery for mapping alteration
  • Evaluate the potential for extrapolating remotely sensed mineral footprints from outcrop/subcrop areas to in-situ covered areas
  • Investigate spatial and/or genetic relationships of sericite-silica and chlorite alteration with high grade sphalerite and galena values

RTR expects the study to be completed in five months, which will run parallel with its current exploration program at the Braeside Project.
