Mamba Exploration (ASX:M24) has identified new copper potential in an area where the company’s main focus has been gold at the Meeka East project tenure in Western Australia.

The internal review of historical geological, drilling and geophysical data across the Copper Hills/Gabanintha area within Meeka East was prompted by renewed regional exploration interest in copper systems in the broader Murchison region, including activity by Solstice Minerals (ASX:SLS) at its Nanadie copper-gold project. That matters for Mamba because the company is now re-examining existing tenure data for a second mineral system without stepping away from its current gold program.

The review has identified potential sediment-hosted copper trends that were not the focus of earlier exploration on the tenure.

Executive director Matt Freedman said the work represents a standalone copper prospect assessment that also supports the company’s ongoing primary gold-focused program at Meeka East.

“The reappraisal points to the potential of a sediment-hosted copper system at Copper Hills, a target style not previously tested on the tenure,” Mr Freedman said.

“A low-cost program of relogging, mapping and geophysical reinterpretation will determine whether dedicated exploration is warranted. While we undertake this work, we continue to prepare to drill at Meeka East Gold, which we look forward to commencing as soon as possible following heritage and regulatory approvals.”

The Copper Hills area has a documented history of small-scale copper mining. In the 1950s, narrow high-grade veins in the “Lady Alma Intrusive” area were worked to recover approximately 971 tonnes at 7.1% copper, which was sold as an agricultural additive.

Mr Freedman said that while these workings were narrow and are not indicative of bulk tonnage, they confirm an active copper-bearing hydrothermal system in the immediate area.

The historic Gabanintha mine, within the same broader tenure, produced copper and gold, consistent with the sediment-hosted hydrothermal model now being applied.

Under the revised sediment-hosted model, Mamba plans to relog historic diamond core against the new stratigraphic framework and rock classification. The company will also generate drill targets for a future dedicated copper program, while continuing the separate permitting path for the gold drilling campaign at Meeka East.

M24 was steady at 1.7 cents, giving the company a market capitalisation of $8.288 million.
