Durkin copper/nickel prospect – Pundinya project
(Marmota Energy Limited (ASX: MEU) 100%)
Calcrete sampling results
Marmota Energy (ASX:MEU) is pleased to announce that it has received calcrete sample assay results from sampling programs covering approximately 50% of the central target zone (Figure 1) at the Durkin copper/nickel prospect. Calcrete sampling is used to more accurately target priority drill zones through the detection of trace elements within a range of samples.
Results are from 197 samples submitted for assay covering the main target zone that extends for approximately 1.2 km, within a larger copper and nickel-in-calcrete anomaly previously defined that extends more than 5km (Figure 1). This is currently considered by the Company to be the highest priority zone for potential drill testing. Remaining assay results covering the northern half of this zone are expected to be received shortly.
The results continue to strongly support the potential for copper – nickel mineralisation at Durkin. The survey is designed to assist in identifying targets for drill testing within the large anomaly zone defined from previously acquired calcrete sampling.

Figure 1: Area of received calcrete assay results shown above within black outlined box.
Assay results* from calcrete samples 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 Ni/Cu projects of this type. Coincident anomalous copper results with grades of up to 129.8ppm Cu were also returned from assay as well as anomalous silver ranging up to 0.78 g/t Ag.

Summary of values for key elements of nickel, cobalt, chromium and copper over the main Durkin target area for 197 calcrete samples are below:
| Element | Samples |
Min | Max | Mean |
|---|---|---|---|---|
| Cu ppm | 197 | 2 | 129.8 | 26.49 |
| Ni ppm | 197 | 5 | 343 | 25.42 |
| Co ppm | 197 | 1.2 | 39.3 | 7.85 |
| **Crppm ** | 197 | 8 | 5224 | 164.88 |
Results from calcrete samples covering the northern half of the main target, along with rock chip samples from outcrop are pending.
- All analyses were undertaken by Genalysis Laboratory Services. The samples are pulverised to 85% passing 75 microns. An aqua-regia partial digest was used with multi-element assays based on ICP-OES (inductively coupled plasma optical (atomic) emission spectrometry) and ICP-MS (inductively coupled plasma mass spectrometry) methodology as appropriate.
Gravity survey
High resolution ground gravity survey data over the project with a 500x500 metre fixed grid gravity station network is being acquired across the Durkin Cu/Ni prospect. The survey results will complement the multi component infill surface sampling which has focused on the large coincident copper and nickel-in-calcrete anomaly (Figure 2).

The new survey will replace regional spaced historic gravity data acquired at an approximate 4 mile spacing during the 1970’s pre GPS. Acquisition is continuing on schedule with approximately 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. The preliminary results over part of the area indicate that the

data will greatly improve the Company’s understanding of the geological framework of the area and be a great aid in targeting drilling.
Airborne Electromagnetic Survey
Fugro Geophysics have mobilised a crew to the Durkin project area to commence a high resolution airborne electromagnetic (AEM) survey. The survey is scheduled to commence this weekend and will cover the northern half of the Pundinya tenement which hosts the Durkin Cu/Ni prospect.
The survey will be flown with Fugro’s HELITEM System which is the world’s most powerful helicopter timedomain electromagnetic system. The high power of HELITEM, coupled with the low noise at the receiver due to its placement above and not in the centre of the transmitting loop, ensures the greatest depth of penetration possible for any electromagnetic system.
HELITEM is offered with a high sensitivity magnetometer to detect magnetic anomalies and map geologic units and structure. The survey is expected to define any conductive features which may be related to the potential copper and nickel or any other mineralisation.
The survey is also expected to provide vital information relating to the potential depth extent and shape of any conductive features mapped. The duration of the survey is planned to be 2 weeks.
Combining the gravity data with good quality conductivity data over the target area will significantly improve the potential for drilling success.
