VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jul 7, 2014) -
Channel Sampling and Mapping Highlights:
- porphyry style alteration and mineralisation extensions identified over a 400m by 150m area

Project Further Upgraded - Tier 1 Porphyry Cu Ag Exploration Prospect:
- high order gold results are associated with outer halo style alteration assemblages

- drill testing to commence shortly
WCB Resources Ltd. ("WCB" or the "Company") (TSX VENTURE:WCB) is pleased to announce the results of the recently completed channel sampling and mapping at the Misima Porphyry Cu Au Prospect on EL1747 in PNG. This program is part of an ongoing systematic exploration strategy which continues to upgrade the Misima Porphyry Cu Au Prospect in preparation for drill testing.
Mapping and Channel Sampling Program
Previous detailed mapping and channel sampling originally identified an area measuring in excess of 800m by 500m within which classic upper level or halo alteration and mineralisation returned highly anomalous copper and gold values (eg 170.9m @ 0.36% Cu, 0.33 g/t Au, 10.10 g/t Ag). These surface results also coincided with a large underlying magnetic high interpreted as possible magnetite alteration, as previously reported. Magnetite can be significant in these systems as it is frequently associated with highly elevated copper and gold grade (eg. Grasberg, Batu Hijau, Golpu, Ok Tedi, Alumbrera, Caspiche).
Recent mapping to the south east of this previously defined area has extended the porphyry style alteration and mineralisation over an area measuring an estimated 400m by 150m. This extension is associated with an interpreted significant north west orientated structure. This structure is defined by surface indications but importantly has a significant underlying elongate north west oriented magnetic high suggestive of magnetite alteration.
A total of 153 channel samples have been collected using a 125mm grinder diamond blade in zones of hard material and with a geological blade hammer in softer zones typically associated with clay alteration. Geological control at each sample ensured that care was taken to ensure accurate volume / hardness relationships remained consistent. Sampling was completed on a geological control basis rather than a set distance relationship to ensure a better understanding of controls on mineralisation. Appropriate QA/QC protocols were completed which included duplicate samples, certified standards and field blanks.
Highly anomalous channel sample results* have been received over an area measuring 400m by 150m where safe access was available from tracks. Minor gaps are observed in the sampling. Where there are gaps in sample continuity but geological continuity continues from mapping, the gap is expressed as a percentage of the total channel.
Results include:
Total Length m | Copper ppm | Gold g/t | Silver g/t | Sampled Length m | Unsampled gaps m | Gaps as % | |
South East Extension | |||||||
Channel 1 | 49 | 310 | 1.65 | 0.58 | 49 | 0.0 | 0 |
Channel 2 | 56.8 | 253 | 1.48 | 1.73 | 46.5 | 10.3 | 18 |
Channel 3 | 52.5 | 129 | 1.80 | 0.82 | 36.5 | 16.0 | 30 |
Comparison of these results with historic channel sampling results obtained by Misima Mines Pty Ltd show excellent correlation.
Cameron Switzer, President and CEO said "These channel sample results not only expand the footprint of the porphyry but also demonstrate the potential high precious metal accumulation in this system. Importantly these results are from halo style alteration styles. Upcoming drilling of the magnetic highs at depth in these areas is exciting."
Quality Assurance/Quality Control
Exploration at the Misima Project is supervised by Cameron Switzer, President and CEO, who is the Qualified Person under NI 43-101. All geochemical information for the Company's projects is obtained and reported under a quality assurance and quality control (QA/QC) program which includes the usage of Standard Operating Procedures and the insertion of Certified Geochemical Standards, appropriate collection of field duplicates.
Channel samples* are collected under the supervision of company geologists in accordance with standard industry practice and are a more accurate representation of the actual grade of the material sampled. Particular attention was taken in ensure accurate hardness volume relationships were maintained throughout the sample program. Results are reported using a 0.1 g/t Au cut off grade.
Sample locations are recorded by GPS devices in WGS84 projection.
Channel samples were assayed by ALS Minerals Brisbane using method 33 elements using ME-ICP61, and for gold by method Au-AA25. ME-ICP61 is a "near total" digestion using 4 acid and ICP-AES. Au-AA25 is used to detect ore grade levels from 0.01 to 100 g/t gold on a nominal 30 gram sample using fire assay with AAS. Cu values over 10,000 are analysed by Cu OG62, Ore Grade Cu - Four Acid. Results are routinely examined by a suitably qualified geologist to ensure laboratory performance meets required standards.
Mr. Cameron Switzer, BSc (Hons), MAIG (3384), MAUSIMM (112798), President and Chief Executive Officer of WCB Resources, is a qualified person as defined by National Instrument 43-101. He is responsible for quality control of exploration undertaken by WCB. Mr. Switzer has reviewed and approved the technical information in this release.
About Misima Project, PNG
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 4.0M ounces of gold and 20M 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. Most recently 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.
The Misima Project, 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 the project from Pan Pacific Copper by spending a total of AUD$9.0M within a staged timeframe subject to standard regulatory approvals.
