Castillo Copper (ASX:CCZ) has received compelling new assays at the Fence Gossan and Ziggy’s Hill Prospect within the Defined Target Area near Broken Hill.
The new cobalt assays for the Fence Gossan and Ziggy’s Hill Prospects are both within the Defined Target Area.
In addition, over 170m of diamond drill-core from five holes within the north-west quadrant (BH1 & BH2; RH3, DD80_IB3 & DD80_RW4/1) have been sent to the laboratory for analysis to test for cobalt, zinc and PGEs.
Defined Target Area
Within the Defined Target Area new cobalt assays – from relatively shallow drilling programmes (surface to circa 100m) undertaken by North Broken Hill Ltd – were discovered for the Fence Gossan and Ziggy’s Hill Prospects, with the best intercepts comprising:
- 23m @ 660ppm Co from 28m including 3m @ 1,300ppm Co from 37m (3E49N)
- 4m @ 925ppm CO from 53m including 2m @ 1,300ppm Co from 55m (3E45N)
- 4m @ 647ppm Co from 46m including 1m @ 1,700ppm Co from 48m (TT05W10N)
- 3m @ 620ppm Co from 52m including 1m @ 1,100ppm Co from 54m (TT05W14N)
- 2m @ 500ppm Co from 7m (TT4W035S)
- 14m @ 262ppm Co from 84m including 1m @ 600ppm Co from 93m (ZIG01)4
- 6m @ 336ppm Co from 39m (RABZIG097)
- 7m @ 250ppm Co from 5m (ZH0210W)
Notably, the Fence Gossan Prospect assays are compelling and align with Tors & Reef Tank results, providing incremental evidence there is potentially an extensive underlying cobalt system within the BHA Project’s East Zone. The new assays are set to be codified then factored into the block model and JORC compliant MRE.
The Fence Gossan Prospect assays are outstanding and provide the Board with increased confidence there is potentially a significant underlying cobalt system within the BHA Project’s East Zone,” Castillo Copper’s CEO Dr Dennis Jensen said.
“In addition, the Board looks forward to receiving the assays for >180m of diamond core from five drill-holes, as it will clarify, firstly, the cobalt potential at The Sister Prospect; and, secondly, if the north-west quadrant is prospective for cobalt, zinc and PGE mineralisation.”
CCZ’s geology team have spent considerable time and effort to prepare 184 one metre lengths of diamond core (at the Broken Hill core library) for follow up analysis.
Pending cobalt assays relating to The Sisters Project (drill-holes BH1 & BH2) are significant, since they will be factored into the block model and JORC compliant MRE. The other drill-holes (RH3, DD80_IB3 & DD80_RW4/1), which includes the Iron Blow Prospect, should provide considerable insight into the cobalt, zinc and PGE potential in the tenure’s north-west quadrant.
