Castillo Copper releases drilling update at Broken Hill project

Highlights:

• At the Fence Gossan prospect, within the BHA project’s east zone, four drill-holes for a total of 516 m were completed, with positive initial observations comparable to the Tors Tank prospect:
  • Targeted cobalt mineralisation zones were hit across the four drill-holes, as sequences intersected comprised clay, amphibolite, schist and gneiss.
  • Numerous disseminated sulfide layers (mostly pyrite linked to amphibolite), up to 17 m thick, were logged which could potentially host cobalt mineralisation.
  • Interpreting the intersected geology suggests it is consistent with observations noted by north Broken Hill in the 1970-80s, while XRF field observations (subject to final assays) indicated cobalt mineralisation is apparent.
• Similar to the Iron Blow Prospect, there are significant magnetite-rich zones – associated with pegmatite up to 19 m thick – which potentially hosts rare earth elements (REEs) and, based on field XRF observations and subject to final assays, PGEs. 
• With four drill-holes completed across the Fence Gossan prospect (eight including the Tors Tank prospect), there is clear positive interpretations implying the underlying geology has the potential, subject to final assays, to host cobalt, REEs and PGEs.

Dr Dennis Jensen, Managing Director of Castillo Copper, commented:

“With the drilling campaign at the halfway mark, the board is optimistic that known mineralisation at the Tors Tank & Fence Gossan prospects has potentially been extended. Moreover, for Fence Gossan in particular, the board is delighted to note the significant pegmatite intercepts which have the potential to host REEs as well as PGEs.”
