Systematic Fieldwork: Super Copper's technical team conducted site visits to more than 15 historical mineral occurrences distributed across the Castilla claim block.
Rock Sampling: A total of 93 rock samples were collected from outcrops, historical mine workings, and surface veins exhibiting visible copper and iron-oxide mineralization.
Geological Observations: Mineralization was observed in quartz veins with sulphides, copper-bearing carbonates, and iron-oxide veins containing specular hematite and magnetite. Vein thickness ranged from a few centimetres up to 3 metres, hosted primarily within Cretaceous quartz diorite and tonalite intrusions.
Historical Grades: Previous surface sampling from 2023 returned values of up to 5.53% copper with 1.7 g/t gold from limited sampling, confirming the potential for significant polymetallic mineralization at low levels.
