Castillo Copper Limited reported the updated JORC (2012) compliant total Mineral Resource Estimate ("MRE") for Cangai Copper Mine which came in at 4.6Mt @ 2.5% Cu for ~114kt contained copper metal. In addition, reflected in the overall MRE are zinc, gold and silver credits that modestly boost the result (15.3g/t Ag; 0.29g/t Au and 0.57% Zn). Castillo's geology team, working in conjunction with a specialist geological consultancy, have produced an updated JORC (2012) compliant Mineral Resource Estimate for Cangai Copper Mine at: o 4.4Mt @ 2.5% Cu inferred insitu and 0.2Mt @ 1.35% Cu indicated from historic stockpiles for ~114kt contained copper metal; augmented further by zinc, gold, and silver credits, In calculating the updated MRE from the 2017 work (MRE: 3.3Mt @ 3.35% Cu for 108,000t1), the geology team factored in reverse circulation and diamond core drilling campaigns undertaken across 2017-18 and used more conservative assumptions to boost the confidence in the revised 2023 MRE, The geology team noted several encouraging observations that underpins significant exploration potential for Cangai Copper Mine, including: The underlying orebody - which commences from surface - is not fully defined, as it remains open to the east, south-east and down dip, There are several sizeable downhole electromagnetic ("DHEM") conductors, proximal to the line of lode, that can potentially extend known mineralisation along strike, With the revised 2023 MRE enhancing Cangai Copper Mine's fundamentals, the Board is highly optimistic Castillo can align with a strategic partner to fully develop the copper potential and map out a viable path to market.
