Munni Munni PGE Project

Artemis owns 70% of the Munni Munni PGE Project, located approximately 40km south of Karratha (Figure 11).

A Reverse Circulation (RC) drilling programme, consisting of 12 drill holes for 1,928 metres, was completed within the current reporting period.  Drill hole locations were spread throughout the entire upper portion of the mineralisation, to a maximum depth of 200 metres. Samples were sent to ALS Global with results pending at the end of this reporting period.

Several RC holes were targeted at replicating the historical diamond drill intersections and provide a comparison with the Artemis 2018 diamond drilling results.  Other zones targeted were designed to help define the position of the PGE horizon. Holes 20MMRC009 & 010 were targeted at shallow VTEM anomalies at the base of the overlying Fortescue Group on the Munni Munni Complex.

The PGE horizon at Munni Munni is a stratigraphic zone and historical drilling has been widely spaced and very selectively assayed.  The recent ARV drilling incorporated a multi-element analytical suite to better define the subtle lithological variations.

Essentially only gabbros and pyroxenites were recognised in the historic diamond drilling with the addition of sediments and various minor intrusive dykes recognisable in the RC chips. This highlights the difficulty in accurately identifying prospective rock types without expensive petrological studies.

When the multi-element results are received from the latest round of drilling, it is anticipated that they will allow more accurate definition of the subtle mafic lithologies based on Al2O3 and MgO content.
