Electromagnetic surveying at Mamba Exploration’s Darling Range nickel-copper-platinum group element project has discovered a series of significant bedrock conductors in the red-hot region. 

Thirteen significant late-time VTEM Max conductors were uncovered during initial work by Mamba (ASX:M24) at Darling Range, which sits in close proximity to Chalice Mining’s (ASX: CHN) Julimar discovery.

Five bedrock conductors were discovered at each of the Mistake Creek and Black Hills tenements, with a further three uncovered at the Batty Bog tenement. The baker’s dozen boasts a combined strike length of more than 7350m.

The conductors are typically associated with magnetic anomalies consistent with signatures of mafic or ultramafic rocks – the type known to host nickel-copper-PGE sulphide mineralisation as at Julimar’s Gonneville intrusion.

Detailed modelling of each conductor is now underway, with planning for ground-based EM and follow-up geochemical sampling also in planning. The modelling and interpretation process is expected to take around three weeks.

The identification of conductors at Mistake Creek also resulted in Mamba applying for a new tenement to cover the southern extension of the area, adding an extra 23km2 to the area.

Mamba’s Managing Director Mike Dunbar said the results were extremely encouraging for the company, which only listed earlier this year and has hit the ground running with exploration programs.

“This is a fantastic result and confirms our belief that this underexplored region of Western Australia has excellent exploration potential which is yet to be fully appreciated,” he said.

“We are very encouraged by the confirmation of the presence of bedrock conductors on each of our tenements, we are also excited to be expanding our tenement package with an additional tenement application to the south of our Mistake Creek tenement.

“Achieving these results, in such a short time from listing, is a significant milestone for the company, and leaves us in a financially strong position to continue our exploration, not only at or Darling Range project, but also at the Great Southern and Ashburton Gold projects, and the Kimberley copper, silver, nickel and cobalt projects as well.”

Chalice (ASX:CHN) is perhaps the best known operator in the Darling Range, with its Julimar discovery contributing to a share price rise of more than 2000% since the beginning of the pandemic.

Julimar sits on one side of Mamba’s Black Hills tenement, which also neighbours a recent EM conductor discovery by Pursuit Minerals (ASX:PUR).

Mandrake Resources’ (ASX:MAN) Jimperding project, which also recently demonstrated strong EM conductors, neighbours Mistake Creek, while Batty Bog is located in between projects owned by Caspin Resources (ASX:CPN) and a recent gold discovery by Liontown Resources (ASX:LTR).

The Darling Range project is situated on the Darling Scarp, a short distance from Perth.
