Ann: High Grade Assays Continue at Callisto, page-3

HIGH GRADE ASSAYS CONTINUE AT CALLISTO Highlights • Assays from the ongoing RC drill program at Callisto confirm palladium-platinum-gold-copper-nickel in the western most drilling undertaken to date • Mineralisation completely open to the west-northwest where a three metre high-grade seam has been discovered in NRC309 • Significant new drill intersections include; o 11 metres @ 1.63 g/t 3E (1) (1.29 g/t Pd, 0.24 g/t Pt, 0.10 g/t Au), 0.22% Cu & 0.27% Ni from 143m (NRC309), including  3 metres @ 2.96 g/t 3E (2.37 g/t Pd, 0.41 g/t Pt, 0.18 g/t Au), 0.44% Cu & 0.43% Ni from 145m o 22 metres @ 1.64 g/t 3E (1.33 g/t Pd, 0.23 g/t Pt, 0.07 g/t Au), 0.23% Cu & 0.26% Ni from 111m (NRC310) o 23 metres @ 1.36 g/t 3E (1.11 g/t Pd, 0.19 g/t Pt, 0.06 g/t Au), 0.20% Cu & 0.23% Ni from 117m (NRC312) • Recent discovery of new disseminated nickel sulphide zone to the north (2), combined with the results from western most drill hole NRC309, highlights the opportunity for new discoveries • Follow up RC drilling planned for western and northern zones • Diamond drilling continuing at south-eastern end of Callisto Galileo Mining Ltd (ASX: GAL, “Galileo” or the “Company”) is pleased to announce drill assays from the ongoing RC drill program at the Callisto palladium-platinum-gold-rhodium-copper-nickel discovery within the Company’s 100% owned Norseman project in Western Australia. Galileo’s Managing Director Brad Underwood commented; “Today’s results show how much we have yet to learn about Callisto and the region’s potential as a newly discovered mineral domain. Metal grades in the western most drill hole NRC309 were a welcome surprise, and it appears that mineralisation is increasing in that direction. The new zone of disseminated nickel sulphides announced on Monday is just 300 metres north of NRC309 and, with no drill holes to the west or north, the capacity for new discoveries in this particular area is high. We are currently completing scout drilling on existing tracks up to one kilometre north of Callisto and then plan to undertake extensive drill programs to the west and north of NRC309 all the way up to the new nickel sulphide zone (see Figure 3). New mineral discoveries present a tremendous opportunity in the early stages of exploration and we believe Callisto is no exception. We look forward to providing updates as work progresses at this exciting new discovery.” Two rigs (one RC and one diamond drill) are continuing to drill at the Callisto discovery with assays received for RC drilling from the northern line 6,448,100N (Figure 2). Results from NRC309 on the western end of the line show that the sulphide zone is gently folded and that the grade in the west-northwest direction appears to be increasing. No drilling exists west or north of NRC309 and this area is now a priority target for follow up RC drilling. The appearance of disseminated nickel sulphides 300 metres to the north of NRC309 is particularly encouraging for the prospectivity of this location (see ASX announcement dated 10/10/2022). The occurrence of a three-metre seam in NRC309 with higher values of palladium, platinum, and gold, is also interpreted as a positive sign for the potential grade distribution in the new zone to the northwest.
