Mamba Exploration identifies new copper-silver targets at Copper Flats project

New tenement applications have also been lodged, doubling the size of the Copper Flats Project ahead of an airborne geophysical survey earmarked for the 2022 field season.
Mamba Exploration’s latest surface sampling at the Copper Flats Project in Western Australia’s Kimberley region has confirmed previous copper prospects and has identified several additional copper-silver targets.
These samples, in conjunction with a detailed review of previous exploration activities, have highlighted the potential of the area to the north of the original Copper Flats tenure.
As a result, Mamba (ASX:M24) has lodged applications for additional exploration licences with the Department of Mines, Industry Regulation and Safety (DMIRS), which more than doubles the size of the Copper Flats Project.
M24 managing director Mike Dunbar said it was very pleasing to confirm the presence of the high-grade copper and silver mineralisation in this underexplored portion of WA.
“To also have highly elevated silver grading up to 230 g/t at the same time is a great outcome,” he said.
“We believe this validates our belief that the Copper Flats Project has significant potential, the scale of which is not yet fully appreciated.
“Not only has the sampling confirmed the high grades from the known prospects, but it has also identified new areas of mineralisation and highlighted a number of structural and stratigraphic targets.
“To achieve this from the first reconnaissance field trip undertaken by Mamba is a great result.”
Notable results from the rock chip sampling include:
Dunbar added that after the field investigation, the technical team identified through historical exploration data that the sedimentary basin is considerably shallower than initially interpreted.
He said as a result, it was identified that the open ground to the north of the project was highly prospective and “that the depth to the basement unconformity target zone would not be an impediment to exploration.”
“Additional tenement applications were therefore lodged with the mines department, more than doubling the size of the project to approximately 2,320 sq km,” he said.
“Given the open file historical exploration identified significant copper and silver mineralisation in the area, it was particularly surprising that this area was vacant and available to be pegged.
“We are now in the process of evaluating and interpreting the available geophysical datasets for the expanded project and planning the next airborne geophysical surveys for the project, which are expected to be undertaken early in the 2022 field season.”
