Mamba Exploration completes soil sampling at Copper Flats, airborne EM survey planned

Mamba Exploration (ASX: M24) has completed a wide-spread soil sampling program at its Copper Flats project, including areas where historical work uncovered up to 30% copper and 275 grams per tonne silver.

Samples were collected from 2,600 sites across the project, and portable XRF (pXRF) analysis has been completed on about half of the samples and returned a peak of 752 parts per million copper.

Readings from pXRF to-date have extended the strike length of the Ord Hill copper target to 4.5km, with mineralisation remaining open to the northeast and southwest.

Mamba managing director Mike Dunbar said Copper Flats covers a “massive area” that extends over 100km to the Northern Territory and Western Australian border.

“As the project name suggests, copper can be found in multiple locations across the project, so finding copper is not difficult – the challenge is finding the controlling structures and stratigraphic locations where the widespread copper mineralisation can ‘blow out’ and form significant zones of mineralisation,” he explained.

He said the latest work had been undertaken with the aim of better understanding the area, including the controls and region’s potential.

Ground truthing of airborne electromagnetic (EM) anomalies was also completed across the project’s eastern portion.

Six of the EM anomalies were visited with none possessing any obvious geological explanation at surface, which Mr Dunbar said was encouraging.

Advancing Copper Flats

A follow-up airborne EM survey is scheduled for next month and will test down dip extensions to where historical rock chips returned up to 30% copper and 275g/t silver.

As the program progresses, it will be expanded to include any additional anomalies.

The company will also use pXRF to test the remaining samples of the program once the team returns to site next week.

These will then undergo wet chemical analysis with results to be reported once they are at hand.
