Ann: Assays Confirm Major Copper Discovery at Big One Deposit, page-14

Game changing assays as two 40-44m wide potentially economic intercepts from surface, with up to 16.65%, significantly extends known mineralisation at the high-grade Big One Deposit o The best apparent intercepts comprise: ❖ 303RC: 40m @ 1.64% from (fm) surface incl: 11m @ 4.40% fm 24m, 5m @ 7.34% fm 28m & 1m @ 16.65% fm 29m ❖ 301RC: 44m @ 1.19% Cu fm surface incl: 14m @ 3.55% fm 27m, 3m @ 10.88% fm 37m & 1m @ 12.6% fm 37m ❖ 213RC: 12m @ 0.79% Cu fm 52m incl: 8m @ 1.06% Cu fm 57m, 3m @ 2.03% Cu fm 58m, 1m @ 4.27% Cu fm 59m & 1m @ 1.46% Cu fm 62m1 ❖ 207RC: 8m @ 0.47% fm 84m incl: 2m @ 1.10% Cu fm 85m & 1m @ 1.49% fm 86m1 ❖ 306RC: 8m @ 0.41% Cu fm 16m and 4m @ 0.97% fm 96m incl: 2m @ 1.30% fm 96m ❖ 206RC: 8m @ 0.42% Cu fm 54m incl: 3m @ 1.02% Cu fm 59m, 1m @ 1.75% Cu fm 60m1 ❖ 302RC: 5m @ 0.66% Cu fm 35m incl: 1m @ 1.30% fm 37m ❖ 305RC: 5m @ 0.53% Cu fm 34m incl: 1m @ 1.19% Cu fm 38m o Encouragingly, the latest assays clearly make the case for potential scaling at Big One Deposit more compelling, especially as the results build materially on early high-grade findings, including: ❖ B07: 3m @ 12.25% Cu fm 42m incl: 2m @ 17.87% Cu fm 43m & 1m @ 28.4% Cu fm 44m ❖ B05: 8m @ 2.33% Cu fm 44m incl: 6m @ 3.00% Cu fm 45m & 5m @ 3.28% Cu fm 45m ❖ B06: 4m @ 2.20% Cu fm 44m incl: 2m @ 3.19% Cu fm 46m ❖ B25: 6m @ 1.55% Cu fm 66m incl: 5m @ 1.79% Cu fm 66m B02: 4m @ 1.45% Cu fm 36m incl: 1m @ 2.48% Cu fm 37m ❖ B26: 3m @ 1.36% Cu fm 73m incl: 2m @ 2.29% Cu fm 73m2 o Key observations CCZ’s geology team garnered from interpreting drill-holes 301RC and 303RC include: ❖ The mineralisation is spread out which is significant given the trachyte to diorite dyke is generally 4-6m wide; ❖ Secondary enrichment is apparent with several samples >10% Cu, likely due to intersected mineralisation occurring in the transitional zone between the oxide and sulphide domains; and ❖ High cobalt grades with 12m @ 912ppm Co fm 29m incl: 1m @ 1,435ppm Co fm 30m (301RC) o Further potential upside should become apparent when assays for drill-holes 307-14RC are received, as visible, shallow copper oxides & sulphides were intersected, comprising: ❖ 307RC: 10m fm 18-28m – Quartz veining, pyrite & chalcocite ❖ 308RC: 10m cumulative – 7m fm 20-27m & 3m fm 28-31m – Quartz veining, pyrite & chalcocite ❖ 313RC: 8.5m from 9.5-18m – Malachite & chalcocite
