Multiple, large electro-magnetic (EM) anomalies – which hold the secret to substantial nickel-copper-PGE mineralisation – have been identified across the Mt Vernon Project area. 

Miramar Resources engaged UTS Geophysics to complete the airborne EM survey at Mt Vernon, one of several exploration licences which make up the company’s larger Bangemall Project in Western Australia’s Gascoyne region.

The tenement was covered with N-S flight lines at a spacing of 400m, compared with the 5km spaced government TEMPEST EM survey lines.

Data received to date shows at least 13 late-time EM anomalies that may indicate the presence of bedrock nickel-copper-PGE sulphides associated with dolerite sills.

In the northeast corner of the tenement several large late-time EM anomalies ranging in strike length from 500m to more than 1.2km have been associated with a dolerite sill.

Historical sampling to the west of these anomalies outlined a large, almost 10km long, PGE anomaly with palladium results up to 25ppb Miramar (ASX:M2R) says, however there is limited previous sampling, and no recorded drilling in the vicinity of the new EM anomalies.

Numerous targets to follow-up

Miramar executive chairman Allan Kelly says the company is “very excited” about the results of the survey.

“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 said.

Next on the agenda

The West Australian focused exploration company is now waiting on 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 and define potential drill targets.
