Initial assays from the first scout drill hole at WCB Resources’ Misima prospect on Misima Island have demonstrated a broad zone of anomalous copper over 188 metres. The diamond drilling is testing a potential tier-1 copper-gold porphyry target.
The first hole was completed to a depth of 723.3 metres. Observed alteration and first initial assays suggest the hole was drilled down the shoulder or pyrite halo of the porphyry system. A second hole is now in progress.
An initial program of up to 4000 metres of reconnaissance scout diamond drilling commenced in mid-September targeting deep strong magnetic features beneath an extensive 1sqkm copper-soil anomaly at the Misima porphyry prospect which coincides with extensive rock chips, shallow drilling and skarn mineralization and halo veining at surface.
Drilling has progressed well with anticipated production rates and good recoveries achieved.
WCB is encouraged by the observations, which suggest that the hole was drilled down the shoulder or pyrite halo of the porphyry system at the Misima prospect and may represent an important incremental step towards the central porphyry zone at depth.
Assay results have so far been received for the interval from 2 to 190 metres of the hole with analysis indicating that the entire interval averages 572 ppm (0.05%) copper. These results are similar to the previous 1969 drill testing completed by Noranda. Individual peak copper results correspond to peak molybdenum and silver results.
These results provide a vector to the southwest of this hole, suggesting that the target central porphyry zone may lie in this area. This gives the company confidence that the second diamond hole has been correctly located to test this target central porphyry zone, where stronger copper mineralization could be expected.
WCB’s president and CEO Cameron Switzer says, “We have made an encouraging start to this drill program at Misima, with the first deep hole targeting the highest order magnetic anomaly and coincident strong supporting geochemistry already completed. The first hole has intersected a broad zone of anomalous copper with some elevated copper values with supporting strong alteration and fracturing, typical of what we might expect to encounter on the shoulder or fringes of a large copper-gold porphyry system.”
