A two-hole (339m) mud rotary/diamond drilling programme (see Figure 1) targeting the strike extensions of the Netherleigh Park Prospect, a north-south de-magnetised carbonaceous siltstone unit 1800m in strike and up to 400m wide, has returned encouraging results including 28m at 0.47% Copper and 12.7g/t Silver (ALDDH006, see Table 1). ALDDH006 finished in an altered zone of mineralisation. Significant Copper mineralisation has now been defined over 200m in strike and remains open both along strike and down dip.
The mineralisation identified to date occurs in breccia and shear zones, in country rocks consisting of early to middle Proterozoic mudstone, siltstone and hornfels. Primary mineralisation consists predominantly of variable amounts of bornite, chalcopyrite, chalcocite, pyrite and hematite, with traces of gold, silver and basemetals. Exploration completed to date indicates that the Alford prospect project shares some of the key features common to an IOCG Olympic Dam style mineralisation.
Recent exploration successes in the region suggest that the most prospective areas are de-magnetised zones with associated gravity highs along the main structural corridors. A number of targets which fit these criteria are present within EL 3037, but to date have been poorly tested or not tested at all. Geophysical modeling of these targets is currently underway and will be the prime focus of the next round of drilling, together with further drilling along strike from the Netherleigh Park mineralisation.
