Figure 6: Location of the El Palmar project (and Verde Chico property) relative to the Llurimagua and Cascabel Alpala and TandayamaAmerica deposits, and the Toachi fault system which is considered important for the localisation of porphyry copper-gold-molybdenum mineralisation in northern Ecuador. Also shown are the concessions held by ENAMI that surround Llurimagua, and which Hanrine (a subsidiary of Hancock Prospecting) have committed to spend US$120 million to earn 49%. El Palmar Copper-Gold Porphyry Project – Northern Ecuador (Sunstone 74.5% - acquiring up to 100%) El Palmar is located in northern Ecuador, 60km north-west of Ecuador’s capital Quito. Sunstone is acquiring 100% of the El Palmar project and currently holds 74.5% under the Staged Acquisition Agreement. The agreement was initially signed on 12th August 2020, with an Amendment signed in June 2024 to enable Sunstone to acquire the outstanding percentage by 30 June 2026. The property sits on the regionally significant Toachi Fault Zone, the same regional structural belt that hosts the 2.66Bt Alpala copper-gold porphyry deposit grading 0.25g/t gold and 0.37% copper, and the 0.53Bt Tandayama-America deposit grading 0.19g/t gold and 0.24% copper within the Cascabel project (see www.solgold.com.au for details), and is in close vicinity of the 1Bt Llurimagua copper-molybdenum porphyry deposit grading 0.89% copper and 0.04% molybdenum (Figure 6). 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 target.
