WCB is pleased to announce that logistical arrangements have been confirmed with the barge carrying the drill rig, support equipment and additional supplies for the previously announced Misima Porphyry Drill Program. The barge is set to depart the city of Lae on August 26, 2014 and is expected to take approximately 5 days to travel to Misima. Drilling is expected to commence approximately 7 days after the arrival of the drill rig on Misima.
About Misima Porphyry Prospect
Originally identified in the mid 1960's via a regional stream sediment sampling program, early drill testing in 1969 defined a modest 0.1% to 0.2% Cu porphyry. Interpretation at the time suggested that higher grade mineralisation could be located at depth. Subsequently the exploration focus shifted to the large area of gold mineralisation on the western side of the porphyry. Exploration drilling then defined the Umuna gold resource from which an estimated 4.0M oz's of Au and 20M oz's of Ag were recovered up until its closure by Misima Mines in 2004.
Regional exploration commenced in late 2011 which accurately defined a high order 1100m by 900m Cu Au anomaly in soils over the area of outcropping porphyry mineralisation. Mapping and channel sampling further refined the outcropping porphyry alteration and mineralisation enabling a higher degree of understanding with respect to the erosive level of the system. This data suggest the current exposure is in the outer or peripheral zone. Magnetic survey data aided in the proposed drill targeting.
WCB subsequently acquired the extensive Misima Mines Database in late 2012 which included over 20 years of exploration drilling, development activity and mining data. Acquisition of the Misima Mines database enabled the definition of the system with numerous halo style drill holes and broad areas of modest Cu in the blast hole data associated with material mined from the Umuna gold resource. This data suggest the current outcrop exposure level is in the outer or peripheral zone of a porphyry Cu Au system.
Synopsis of this data suggest that WCB has defined a zone with a footprint in excess of 1 Mt per vertical metre with an average grade of 0.37 g/t Au, 866ppm Cu and 3.1 g/t Ag (based on all data including Misima Mines' channel sampling and blast holes, as well as WCB's channel sampling). Importantly, higher economic Cu and Au grades are returned when magnetite alteration is observed. Magnetic data suggest that the large high order magnetic anomaly does not reach surface and has not been previously drill tested. This is further supported by previous exploration drill holes which return halo style intersections over a 1500 m by 1000 m area. Halo drill holes have been critical in several recent significant discoveries.
About EL1747 Misima
Giant Cu Au deposits such as Grasberg, Ok Tedi, Panguna and Wafi-Golpu, as well as the giant Au deposit Lihir are developed in this region. Misima Island is located on the extensions of this terrain and has previously demonstrated mineral deposit pedigree through the past production of 4.0 M ounces of gold and 20 M ounces of silver from various operations but most recently the Misima Mine owned by Placer Dome Asia Pacific. This mine ceased open pit production in 2001 and closed in 2004. WCB released a NI43-101 compliant inferred resource containing 1.57M ounces gold and 8M ounces silver associated with extensions of the previously mined zone.
EL1747 Misima consists of 53 sub blocks covering an area of 180km2. The exploration license was targeted due to the presence of a significant gold mineralising system in conjunction with significant high order copper stream sediment anomalies in multiple drainages which had received limited detailed systematic follow up.
WCB can obtain up to a 70% interest in EL1747 Misima from Pan Pacific Copper (through its subsidiary Gallipoli Exploration (PNG) Ltd) by spending a total of AUD$9.0 M within a staged timeframe subject to standard regulatory approvals. WCB has obtained an initial 30% equity interest in Gallipoli Exploration (PNG) Ltd and is well progressed towards an additional 19% interest.
