Miramar Resources Limited (ASX:M2R) has expanded its land position within the “Bangemall Project”, in the Gascoyne region of Western Australia, which Miramar believes is prospective for Ni-Cu-PGE (+/- REE) mineralisation.
The company has pegged a new application, E08/3498, immediately adjacent to an earlier application which is currently progressing to grant. Together, the two applications cover Proterozoic dolerite sills and the contact between the Edmund and Collier Basins.
In addition, several later NE-trending dolerite dykes of the Mundine Well suite are seen in the vicinity. These later dykes are apparently related to the Money Intrusion which hosts the high-grade Ni-Cu-PGE mineralisation discovered at Dreadnought Resources Limited’s “Mangaroon” project.
Historical exploration
A compilation of historic rock chip and stream sediment samples over the “Blue Bar” target has revealed several strongly anomalous Ni and Cu results. Of note, are several rock chip samples with strongly elevated Ni and Cu results (up to 738ppm Ni and 218ppm Cu respectively) in a “strongly weathered ironstone” located at the contact between the Edmund Basin and the Collier Basin (reference WAMEX a078053).
No Au, Pt or Pd assays are recorded. No dolerite is mapped is this area, but the regional magnetic data suggests the presence of a dolerite sill, and outcropping dolerite is recorded to the southeast. A cluster of strongly anomalous rock chips is also recorded along strike to the northwest and outside of Miramar’s tenement.
Sampling within Miramar’s tenements is sporadic and the total potential strike length is over 30km. In the north-western corner of the project tenements, a single rock chip sample, CAPR0428, returned 2,970ppm Ni and 1,230ppm Cu (reference WAMEX a081037). No geological information is recorded about the sample and no Au, Pt or Pd assays are recorded.
Based on the regional magnetic and geological data, this strongly anomalous sample lies close to or within one of the NE-trending Mundine Well dykes.
Historical stream sediment sampling parallel to the northern margin of the Kulkatharra dolerite sill shows multiple coincident anomalous Ni and Cu results in streams draining off the dolerite over a strike extent of approximately 8km (reference WAMEX a053636). No Pd or Pt assays are recorded for these samples.
Executive Chairman, Allan Kelly, said the presence of highly anomalous nickel and copper results apparently associated with Mundine Well dykes was extremely significant given the recent results coming from Dreadnought Resources Limited’s Mangaroon Project.
Blue Bar has the most significant historical nickel and copper assay results of any of the targets we have identified at Bangemall to date,” he said.
“The apparent spatial association of the results with the later Mundine Well dykes adds a further dimension to the prospectivity of our strategic Bangemall landholding and we look forward to getting on the ground and examining the opportunity further.”
Upcoming Work Plans
The company is finalising plans for a helicopter-supported geochemical sampling campaign over the multiple late-time EM anomalies outlined at Mt Vernon and will conduct a reconnaissance field visit to the Blue Bar target as part of this work programme.
Following grant of the Blue Bar tenements, the Company plans to conduct an airborne EM survey over the project and follow up with surface geochemical sampling.
