Miramar Resources Limited (ASX:M2R) has identified multiple large late-time EM anomalies via its recently completed airborne EM survey at its 100% owned Mt Vernon target in Western Australia.
The company believes the large late-time EM anomalies may indicate the presence of Ni-Cu-PGE mineralisation.
Mt Vernon is one of several Exploration Licences and/or Applications which make up the company’s “Bangemall Project”, in the Gascoyne region of WA, which Miramar believes is prospective for Ni-Cu-PGE (+/- REE) mineralisation.
The Mt Vernon target is characterised by several large historic PGE stream sediment and/or soil anomalies associated with Proterozoic dolerite sills and adjacent to major crustal-scale structures.
The “VTEM Max” survey was completed by UTS Geophysics and covered the tenement with N-S flight lines with a line spacing of 400m, compared with the five km spaced government TEMPEST EM survey lines.
Preliminary data has been received and has highlighted at least 13 late-time EM anomalies that may indicate the presence of bedrock Ni-Cu-PGE sulphides associated with dolerite sills.
In the northeast corner of the tenement, several large late-time EM anomalies are seen associated with a dolerite sill.
The anomalies range in strike length from 500m to over 1.2km. Historical soil sampling to the west of these anomalies outlined a large, almost 10km long, PGE anomaly with Pd results up to 25ppb, however there is limited previous sampling, and no recorded drilling, in the vicinity of the new EM anomalies.
Executive Chairman, Allan Kelly, said the company was very excited about the results of the survey and looked forward to following them up on the ground.
“We’ve outlined a number of large late-time EM anomalies, apparently associated with Ni, Cu and PGE anomalism, in a virtually unexplored area,” Mr Kelly said.
“These results are exactly what we would have hoped to see from this survey, validate our views on the prospectivity of this project and give us numerous targets for follow-up work,” he added.
Magnetic data collected with the EM survey also shows a large elliptical feature in the west of the project which may represent an unmapped intrusion.
Gravity data is too widely spaced to provide any useful information about this feature.
Proposed further work
The company is waiting on the final data from the Contractor and will model the most prospective anomalies once this data is received.
Future work will include field checking of the anomalies, along with surface geochemical sampling and prospecting, with a view to conducting ground EM surveys in order to define potential drill targets.
