Mamba identifies several bedrock conductors at Copper Flats Project in WA

Mamba Exploration (ASX:M24) announces that detailed 2.5D inversion modelling of regional (20km spaced) airborne EM data has identified several bedrock conductors at the Copper Flats Project in the east Kimberley of Western Australia.

The conductors are coincident with the interpreted basin growth faults and ‘high-grade’ copper and silver grades identified in surface sampling.

In addition to the bedrock conductors, the modelling has clearly identified the regional stratigraphy and recognised a number of structures.

Commenting on the modelling, Mamba Managing Director Mike Dunbar said: “We are pleased to announce that the detailed inversion modelling of the regional AEM dataset has identified bedrock conductors at Copper Flats.

“It is very encouraging that the conductors are coincident with the interpreted basin growth faults and the high-grade copper and silver surface sampling”

It is very encouraging that the conductors are coincident with the interpreted basin growth faults and the high-grade copper and silver surface sampling that Mamba completed in 2021 and the historical surface data.

There are also several strong conductors in areas which have not had any surface sampling undertaken.

The AEM has not only identified bedrock conductors but has also clearly mapped out the basin stratigraphy and identified a number of structures which disrupt the EM response in several locations, confirming the company’s geological interpretations.

Given the regional lines are so wide spaced (20km) no interpretation between lines can be undertaken, however it is believed that acquisition of a detailed EM data will be invaluable in targeting high-grade copper and silver mineralisation.”

Mamba reports that it has already planned a large, detailed survey to cover the northeast portion of Copper Flats. A contract for the survey has been signed, with the survey to be flown in October this year.

The soil sampling program is also progressing over the Ord Hill prospect with around 60% of the 2,600 samples already collected with XRF analysis of the priority samples expected to be completed in the next two weeks, allowing follow-up sampling to be completed prior to the  field team mobilising to its other project.

Mamba is a Western Australia-focused exploration company, with four 100% owned geographically diverse projects which provide year-round access.

The projects are highly prospective mineral exploration assets in the Ashburton,  Kimberley, Darling Range and Great Southern regions of Western Australia.

The projects in the Ashburton and Great Southern are prospective for gold whilst those in the Kimberley and Darling Range are prospective for base metals such as copper, nickel, PGEs and manganese and REEs.
