WCB Resources is encouraged by recent diamond drilling at the Misima Porphyry Copper Prospect on Misima Island, where it is testing a potential tier-1 copper-gold porphyry target. WCB says one hole has encountered a major structural zone with alteration, veining and mineralization consistent with the upper levels of the porphyry system.
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 mineralisation and halo veining at surface.
The initial diamond hole was completed to a depth of 723.3 metres down-hole and encountered alteration and geochemistry consistent with the margin or shoulder of a porphyry system and provided an excellent vector for the second hole.
This hole was collared on section 240 metres to the southeast and encountered interbedded skarn and marble to a depth of 85 metres. Beneath the skarn zone the sequence was interbedded Ara Schist and intrusives to a depth of 550 metres when the hole intersected a post mineral intrusive to 768 metres, where the hole was completed.
Importantly, visible secondary copper including well developed gossanous zones were observed in the upper skarn zone. Minor visible gold was also observed in selected zones over several metres. Beneath the skarn, the interbedded intrusives and Ara Schist contained well developed sulphide including pyrite and accessory chalcopyrite to 550 metres. Included in this zone are three discrete zones totalling 180 metres downhole in which magnetite chalcopyrite stockwork of variable intensity is developed.
WCB’s president and CEO Cameron Switzer says, “This scout drill program continues to provide encouragement. The second hole has intersected a broad zone of sulphide development including magnetite alteration which has previously returned high grade results on surface. The third hole has commenced and will drill beneath well-developed surface geochemistry and geology.”
Drilling has progressed well with anticipated production rates and good recoveries achieved.
WCB Resources is an aggressive minerals exploration and development company that brings together a strong, interdisciplinary, and proven management team with the ability to take a project from discovery right through to operation. WCB is focused on the exploration and development of the Misima project.
Cameron Switzer says, “The drilling on this porphyry prospect is the result of a systematic exploration campaign that commenced in 2012 and marks an exciting phase of activity for WCB. All of our previous exploration supports the thesis that this is a tier 1 prospect. Deep drilling is the ultimate test in these porphyry systems.”
