Marmota Energy (ASX: MEU) has secured further evidence supporting the potential for copper/nickel mineralisation at the Durkin prospect of its Pundinya project in South Australia.
Calcrete sample assay results from 197 samples covering the main target zone have included anomalous grades for nickel of up to 343ppm with associated vectoring elements chromium and cobalt returning grades of up to 5224ppm and 39.3ppm respectively.
The association of copper, nickel, cobalt and chromium is considered critical and a positive sign for the project as they are all very common in other nickel/copper projects of this type.
Coincident anomalous copper results with grades of up to 129.8ppm copper were also returned from assay as well as anomalous silver ranging up to 0.78 grams per tonne silver.
The survey is designed to assist in identifying targets for drill testing within the large anomaly zone that extends for more than 5 kilometres.
A 1.2 kilometre main target zone is considered to be the highest priority zone for this drill testing.
Further assay results covering the northern half of this zone are expected to be received shortly.
Marmota is also acquiring high resolution ground gravity survey data over the project with a 500x500 metre fixed grid gravity station network.
This will complement the multi component infill surface sampling which has focused on the large coincident copper and nickel-in-calcrete anomaly.
The new survey will replace regional spaced historic gravity data acquired at a roughly 4 mile spacing during the 1970’s. Acquisition is continuing on schedule with about 70% of the survey completed.
It is estimated that the survey will be completed in coming days with final results expected to be delivered within a week of end of acquisition.
Preliminary results indicate the data will greatly improve the company’s understanding of the geological framework of the area and be a great aid in targeting drilling.
Marmota will also start a airborne electromagnetic over the northern half of the Pundinya tenement.
This is expected to provide vital information relating to the potential depth extent and shape of any conductive features mapped.
