Conductive plate’s interpreted to be ~500m from major magnetic anomaly, providing more compelling evidence of high-grade potential below established shallow mineralisation
Nimy Resources (ASX:NIM) is pleased to announce that it has made a significant breakthrough in its search for the source of the extensive copper-nickel mineralisation at its Masson discovery in WA. A DHEM survey at Masson, which was drilled to a depth of 444m south along strike from the Masson Discovery holes, has identified three conductive plates close to a large previously-identified magnetic anomaly.
Nimy considers the results to be highly significant because the close proximity of the plates to the magnetic body suggests this anomaly may be a source of the copper, nickel and PGE’s found in shallow drilling
The key points to note concerning these results are:
- The high conductance and size of the modelled plates (upper plate extending 240m at 5,250 S – Plate A, lower plate extending 100m at 4,000 S – Plate B) indicate that the mineralisation continues well beyond the deepest hole successfully targeting mineralisation drilled at Masson.
- Previous drilling has returned highly anomalous copper, nickel and PGE in sulphide mineralisation from a depth of 91m to 288m. The new upper plate indicates mineralisation extends to 340m with the lower plate extending the highly conductive trend by a further 100m.
- The high conductive trend is plunging to the south towards a high magnetic anomaly identified from VOXI depth slice modelling. This anomaly represents a possible source of Masson mineralisation.
- The dip direction and plunge of the lower plates indicates a levelling of the mineralised zone toward the magnetic anomaly.
- A third plate was modelled and is a lower-confidence plate surrounding Plate A with a much lower conductance of 350S and may indicate a broader, lower conductance Cu mineralised zone.
- Plates have been modeled to the limit of survey data collected, meaning that the mineralisation remains open at depth below the lower plate.
- Samples from the upper 208m (RC) of hole NRRD165 have been delivered for assay, diamond core has been delivered for detailed geological logging and initial box scan XRF, whereby core samples will be selected for assay.
Managing Director, Luke Hampson, commented:
These latest geophysics results provide more strong evidence of the potential for a significant body of high-grade copper and nickel at Masson. We now have three key pieces of firm supporting evidence: known shallow mineralisation, and three nearby connected conductive plates vectoring toward a large magnetic anomaly.
This survey has successfully expanded the footprint and indicates a substantial accumulation of copper dominant massive sulphide mineralisation.
Masson is the first of many targets generated from our large-scale VTEM survey to be drilled. Nimy Technical Geologist Dr John Simmonds is interpreting and prioritising a number of possible repeats of the Masson discovery.
Masson is developing into a large copper nickel PGE target with the target area now substantially increased at depth and along strike, and it remains open”.
