Miramar Resources Ltd (ASX:M2R) has identified multiple electromagnetic (EM) conductors within the Dooley Downs tenement application, part of the Bangemall Nickel-Copper-PGE Project in the Gascoyne region of Western Australia.
This follows a review of historical data from the Dooley Downs tenement (E09/2484), one of seven 100% owned-granted exploration licences held by Miramar in the region.
M2R believes the Bangemall Project is prospective for craton-margin nickel-copper-PGE mineralisation, such as that discovered at Nova-Bollinger and Nebo-Babel, and the giant Norilsk and Voisey Bay deposits.
The 160-metre line-spaced data shows a series of linear EM anomalies interpreted to be related to the various dolerite sills and/or sulphidic sediments.
Interestingly, several discrete EM anomalies, in the order of 400-500 metres diameter are adjacent to the stratigraphic conductors.
Bangemall projects showing regional geology, major structures and Proterozoic dolerite sills.
These smaller anomalies appear in both the late time (Channel 30 – 11.7 metres) and deeper depth slice (60-100 metres) images and appear to coincide with areas of demagnetisation within strike-parallel structures.
Historical EM survey data showing stratigraphic and pinpoint EM conductors.
Historical surface geochemical sampling has been sporadic and mostly focused on exploration for manganese.
Several historic rock chip samples are reported to contain malachite, but most samples have not been assayed for nickel or copper and no samples have been taken directly over the EM conductors.
Miramar plans to model the EM data and will field-check the anomalies once the tenement is granted.
