Aruma identify high-priority targets at Bortala Copper Project

2 July 2024 14:35

Aruma Resources Limited (ASX:AAJ) has announced the identification of multiple high-priority exploration targets at its recently acquired Bortala Copper Project in the Mt Isa copper belt, Queensland. This development comes as part of a broader portfolio of copper and uranium exploration assets Aruma acquired in Queensland and South Australia.

The Bortala Project is located just south of 29Metals’ high-grade Capricorn Copper Mine, and is interpreted as being prospective for uranium, stratiform copper-gold and iron-oxide copper gold (IOCG) mineralisation.

R9 target

The initial exploration has defined several high-priority copper-gold targets within the Bortala Copper Project. The work verified the presence of an outcropping epithermal-like vein at the R9 copper-gold target, containing rock chip assays with up to 1.9g/t gold.

Previous drilling by Ashton Mining in 1988 provided encouraging results, including:

      • 18m at 0.18% Cu from 29m
      • 2m at 0.25g/t Au from 46m
      • 4m at 0.36% Pb from 45m
      • 5m at 0.44% Zn from 41m

Exploration Plans

Aruma has outlined a clear path forward to further explore and define these targets. The next steps include surface sampling and geophysics, where a comprehensive surface sampling program will be initiated to refine drill targets. This will be supported by geophysical surveys, including ground gravity and Induced Polarisation (IP) studies.

Subject to the results of the surface sampling and geophysics, Aruma plans to commence drilling in 2024.

Management comments

Glenn Grayson, Aruma Resources Managing Director, expressed optimism about the initial findings. “We are encouraged by this initial appraisal of the [Bortala] Project. We see significant potential, highlighting the area around the R9 copper-gold anomaly. Notably, the presence of coincident uranium and copper-gold mineralisation underlines the Project’s IOCG potential, which will be a core focus of our exploration programs.

Bortala already displays a significant target footprint, with numerous prospective areas identified, but remains largely under-explored. In combination, this presents the Company with an exciting pipeline of exploration from which to drive shareholder value.”
