SILICA HILL CONTINUES TO GROW
Mineralised vein system extended to 250 metres along trend and still open.
Potential further extension of 300 metres along trend indicated by extensive zones of narrow veins with gold-silver-pathfinder metals characteristic of the upper, less mineralised parts of the system. Priority drill target at depth below these veins.
Wide copper intersect indicates increasing copper and possible porphyry coppergold system at depth. Downhole EM survey to define more specific drill targets.
Mineralised system now extends over 500 metres of trend and 400 metres vertical extent.
A significant expansion of the exploration potential over at least several hundred metres along trend and also at depth is being revealed in the on-going drill programme at Impact Minerals Limited’s (ASX:IPT) high grade gold-silver discovery at the Silica Hill Prospect, part of the 100% owned Commonwealth Project, 100 km north of Orange in New South Wales. Recent diamond drill holes (CMIPT64 to 66) have now extended the mineralised vein system, which comprises a stockwork of quartz-sulphide veins about 40 metres wide, a further 50 metres along trend to the north east and comprising multiple narrow veins containing measurable silver with a hand held XRF instrument (Figure 1).The vein system is now about 250 metres in length and is still open along trend and at depth (see announcements dated 15 August 2017 and 4 August 2017)

FURTHER HIGH GRADE RESULTS AT SILICA HILL
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.
