HIGHLIGHTS · ·
The Board is pleased to announce the cobalt-focused drilling campaign at the BHA Project's East Zone is now underway Over the next four weeks, the team will complete one diamond core and 17 RC drill-holes for 2,100m across four prospects1: o The Sisters: two drill-holes testing for cobalt-copper-REEs o Reefs Tank, Tors Tank, Fence Gossan: 16 drill-holes testing for cobalt-copper-gold-silver
· A key focus is drilling two lower potentially cobalt-rich zones at Fence Gossan, Reefs Tanks & Tors Tank, which are interpreted to host higher-grade mineralisation than modelled to date1 · Holistically, the strategic intent remains extending known mineralisation plus enhancing the confidence & grade of the current global mineral resource estimate (MRE) - 21,556t cobalt (64Mt @ 318 ppm Co) and 44,260t copper (63Mt @ 0.07% Cu)2 Dr Dennis Jensen, Managing Director of Castillo Copper, commented: "This is an exciting time for Castillo Copper as drilling is now underway at our 100% owned BHA Project's East Zone. The geology team have designed a comprehensive drilling campaign and the Board is optimistic the strategic intent to increase the confidence and grade of the current MRE is achievable."
