Sunstone Metals Annual Report 2024

Figure 5: Plan map showing the drilling to date at the T1 target at El Palmar, the location of recent trench results, and the relative locations of the T1-T2-T5 porphyry-epithermal cluster. Operating Review continued Sunstone has identified five porphyry gold-copper targets, with mineralisation extending from surface at the T1, T2 and T5 targets covering an area of 600m by 600m, and mineralisation at depth for the T3 and T4 targets. Trenching results returned in July 2024 continue to enhance the potential for a significant Mineral Resource. Assays expanded the shallow mineralisation adjacent to the T1 target while providing further evidence for deeper, larger porphyry deposits. Strong stockwork-hosted porphyry gold-copper mineralisation has been uncovered by trench P7-3e at the T5 target immediately south of the large T1 target (sampling intersected 30m at 1.18g/t gold, including a 2m interval of 9.99g/t gold and 0.11% copper). At the same time, porphyry-related epithermal mineralisation was also identified in trench P7-1 at the T2 target, located immediately east of the large T1 target (trench sampling intersected 13.0m at 0.47g/t gold in trench P7-1e and 8.0m at 0.82g/t gold in trench P7-1f, which correlated well with drill hole EPDD024).
