MULGARRIE - Western Australia
Falcon 30%, Hemisphere 70%
The Mulgarrie Project comprises tenement E27/314, covering prospective komatiite stratigraphy, 15 - 20km north and along strike from the Silver Swan nickel deposit
Widespread nickel anomalism was returned by previous aircore drilling at the Drumstick, Wishbone East and Wishbone West Prospects, together with several shallow EM conductors (See Figure 6). Further deeper drilling is warranted to test for primary nickel sulphides beneath the weathering zone.
During the year Hemisphere completed one follow-up diamond drill hole (HMDD002) to a final depth of 303 metres at the Drumstick Prospect (Figure 6). The drill hole was designed to test a strong off-hole conductor in HMDD001 for primary massive nickel sulphides. The geophysical modeling of the down hole and surface EM data indicates a steeply dipping body of about 300m in down dip extent and greater than 200m strike length located about 200m below the surface.
Drill hole HMDD002 was drilled to test the central portion of the geophysical anomaly discussed above and intersected three sulphidic zones with anomalous nickel in association with pyrrhotite and minor chalcopyrite (Table 3 below). Re-interpretation of the geological data suggests that the prospective basal mafic-ultramafic contact dips to the north-east and was intersected closer to the surface than expected. Further drill testing is required.
