28 Impact Minerals Ltd Annual Report 2022 Figure 7.2: View looking South of the copper halo (red bubbles >100 ppm copper, green bubbles >200 ppm copper) with an associated molybdenum halo (>2 ppm molybdenum). Thick intercepts of low to modest grade copper occur over an area of at least about one square kilometre. Figure 7.3: Summary of the geology and copper values around the Ridgeway deposit located near Orange in NSW. Note the very low levels of copper present in so called “unremarkable” altered rocks even as close as 200 metres to 300 metres away from the high grade core (RHS of Figure). Distinctive alteration halos only occur within 10’s of metres thick around high grade zones. The cross section shows a deposit would be easily missed unless the drill spacing was about 200 metres between holes. of many hundreds of metres between most drill holes (Figure 7.2). The Ridgeway deposit, which lies 400 metres below surface, was not discovered until the drill density was at a spacing of 200 metres by 200 metres between drill holes (Figure 7.3). Accordingly there is plenty of scope to find a Ridgeway sized deposit within the copper halo at Apsley. Three Areas For Follow Up Work Identified Within the large copper halo three broad areas for follow up work (T1, T2 and T3: Figure 7.4) have been identified based on zonation patterns in pathfinder and commodity metal assemblages which are being increasingly used as vectors towards ore in exploration for porphyry copper-gold deposits (ASX Release 10th August 2020).
