| ABSTRACT: | Further drill assays from the on-going drill programme at Impact Minerals Limited’s (ASX:IPT) emerging gold-silver discovery at the Silica Hill Prospect, part of the 100% owned Commonwealth Project 100 km north of Orange in New South Wales, continue to confirm and expand the bulk-tonnage potential close to the near-surface high grade massive sulphide resource at Main Shaft, with only 10% of the target area tested to date close to surface. In addition the closed spaced drilling completed to date has elucidated further important structural controls on high grade shoots as well as the broad vertical and lateral metal zonation within the stockwork vein system (Figures 1 and 2). East-west trending structures have now been identified as an important control of the high grade zones and shoots within the overall north east trending zone of mineralisation, and it has been shown that the entire vertical extent of the mineralised system has been preserved from an upper barren silica-pyrite zone that passes progressively down and laterally through low grade silver +/- gold veins; higher grade gold and silver veins; and a lower zinc-lead-copper zone containing “feeder veins” of massive base metal sulphides that also have high grade gold and silver in places. An intial interpretation of these results combined with detailed logging of the diamond core, shows that the overall north east trending corridor of mineralisation at Silica Hill is resolving into several mineralised domains related to east-west trending, steeply south dipping structures (Figure 1). The intersection of the east-west and north east trending structures appears to be a strong control on the higher grade portions and shoots of the mineralised system. At least two east-west structures have been identified, each over at least 400 metres of strike and both open along trend and at depth. | |
