Verde Chico Project Sunstone is acquiring the Verde Chico Project through a Staged Acquisition Agreement signed on 23 September 2022. Verde Chico is located to the west of Sunstone’s El Palmar gold-copper porphyry discovery and quadruples Sunstone’s land position to 3,672ha in this highly prospective copper-gold belt. The Verde Chico project was explored by the Rio Tinto group (then called RTZ) in 1992-1995, and by Canadian junior Balaclava Mines in 1998. No exploration has been undertaken on the land since 1998. The historical exploration identified a 1.1kmlong gold-in-soil anomaly that is open to the north and south, and which includes several high-grade gold-bearing veins at surface and wide lowergrade zones of gold mineralisation in some drill holes. A total of 12 trenches for 683m were opened and sampled following mineralised structures. A total of 28 drill holes for 4,436m were drilled by RTZ and Balaclava. Historical exploration comprised regional stream sediment sampling, soil sampling, limited geophysics (CSAMT), trench sampling, and diamond drilling. The soil sampling by Rio Tinto, which defined the >1.1km long gold-in-soil anomaly, is coincident with a CSAMT resistivity anomaly. This area was drilled at several locations and returned significant intervals of gold mineralisation including 68.5m at 1.05g/t gold from surface in hole RVC-08, including 1m at 11.3g/t gold from 40.5m.
