![Highly Significant Channel Sampling Results Further Upgrades the Misima Porphyry Cu Au Project, PNG](https://www.goldseiten.de/media/goldseiten-news.jpg)
- results include 170.9m @ 0.36% Cu, 0.33 g/t Au and 10.10 g/t Ag
- confirms the existence and continuity of highly anomalous Cu Au and Ag geochemistry in the interpreted peripheral levels of a large porphyry Cu Au system
- mineralisation is similar to observed styles in other large porphyry deposits
- high order geochemistry is developed in propylitic and minor phyllic alteration assemblages which are typical of the outer zones or distal areas of a large porphyry system
Project Further Upgraded - World Class Porphyry Cu Ag Exploration Project:
- in addition to the exploration to date (soil sampling and aeromagnetic surveys recently completed) the channel sampling and mapping reinforces the status of this porphyry Cu Au project as a Tier 1 Exploration Asset
- the footprint of the project continues to grow
- mapping continues to expand the system
- drill targeting underway
VANCOUVER, July 9, 2013 - WCB Resources Ltd ("WCB" or the "Company") (TSX VENTURE:WCB) is pleased to announce the results for the recently completed sawn-channel sampling and mapping at the Misima Porphyry Cu Au Project in PNG. This program is part of an ongoing systematic exploration strategy which continues to upgrade the Misima Porphyry Cu Au Project. The receipt of this new data confirms the existence of a potentially significant precious metal rich porphyry Cu style target.
Cameron Switzer, President and CEO said "These channel sample results yet again highlight the robust nature and upside of this project. The data significantly upgrades the project from a number of perspectives.
Firstly, the surface expression or footprint where the stockwork veining and skarn is developed, is comparable to many other commercial projects throughout the world.
Secondly, the level of Cu Au and Ag anomalism is significant given that the alteration indicators, geological data and geochemical vectors point to the peripheral or distal regions of the system. Typically, in these types of deposits the zone where the majority of the metal is located has not yet been tested at Misima.
Thirdly, we have now demonstrated that this system has significant by-product precious metal credits which are critical additions to the overall potential value. In addition, the complex geological relationships, including the vein types and density, all point to a strong hydrothermal system with significant potential. Management and the Board are further encouraged as mapping continues to expand the system to the north, east and south. This data along with the magnetic data are critical for drill targeting."
Mapping and Channel Sampling Program
Detailed mapping and channel sampling have now been completed over an area measuring in excess of 800m by 500m. This area has been previously outlined by the soil sampling program which defined the large 1,100m by 900m coincident Cu Au Mo soil anomaly (see announcement 06/14/2012). This mapped area also covers the intense magnetic high as previously outlined (see announcement 08/07/2012).This data has been collected as a prelude for drill targeting.
Mapping and sampling have utilised old tracks and benches from the Umuna Gold Mine. Vegetation was cleared allowing for continuous exposure. Where Risk Assessment Analysis indicated areas of High Potential, no sampling was undertaken.
A total of 452 channel samples have been collected with 125mm grinder diamond blade in zones of hard material and with 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, standards and field blanks. All sample locations were surveyed using GPS devices. (For detailed information refer to QA/QC section).
Detailed geological mapping has recorded rock type, alteration type, vein type, vein percentage, structural orientation and sample interval. Data indicate a complex series of field geological relationships between the host Umuna Schist unit, the Ara Greenshist, the Halibu Limestone and the Boiou Granodiorite. Intense localised dykes, sills and small stocks of porphyritic andesite, dacite and latite intrusive are also observed.
Alteration observed is host rock dependent with the schist units, Boiou Granodiorite and Latite intrusives having variable illite-sericite-chlorite-hematite alteration. The Ara Greenschist typically has significant volumes of chlorite-hematite with localised accessory epidote. Actinolite has also been observed. Numerous limestone lenses are observed with alteration ranging from recrystalised marble to zones of intense magnetite-chlorite skarn.
Vein type ranges from classic porphyry style with well developed ex sulphide median line, to upper level quartz veins with open space and texturally non descript quartz veins. Minor quartz magnetite veining is observed at lower elevations. Late stage overprinting pyritic veins are also observed along with carbonate dominated veins. The veining is developed as multi directional veins, stockworks and vein swarms with mapping suggesting equal vein development in all rock types. Vein densities have been measured on a regular interval basis and vary from 1% to 2% by volume to greater than 50% in localised areas.
Structural data suggest multidirectional vein orientation within which several dominant directions can be related to larger major structural features that are readily observable in the magnetic data and geological data.
Highly anomalous channel sample results* have been received over an area measuring 800m by 500m where safe access was available from tracks and benches. Minor gaps are observed in the sampling as a result of the Risk Assessment indicating an area of high potential or area of slippage. Results from this sampling are expressed in metres. Where there are gaps in sample continuity but geological continuity continues from mapping, the gap is expressed as a percentage of the total channel.

Comparison of these results to historic previous channel sampling results completed by Misima Mines Pty Ltd show excellent correlation. Compilation and validation of this data including historic channel sampling is continuing.
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. Samples are dispatched via commercial transport to ALS Minerals Ltd Brisbane, an accredited laboratory in Australia for analysis. Results are routinely examined by a suitably qualified geologist to ensure laboratory performance meets required standards.
Results are reported using a 0.1% Cu (1000 ppm) 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.

About EL1747
From a geological and mineral deposits perspective, EL1747 is located in the same terrain and geological region that includes the deposits of Grasberg, Ok Tedi, Hidden Valley, Wafi-Golpu, Lihir, Simberi and Panguna as well as significant projects such as Tolukuma, Kainantu and Woodlark Island. Misima Island has previously demonstrated mineral deposit pedigree through the past recovered 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.
EL1747 Misima consists of 53 sub blocks covering an area of 180km2. The exploration license was targeted due to the presence of a significant high order copper stream sediment anomaly in multiple drainages which has received limited detailed follow up activity. Furthermore, additional high order gold and zinc anomalies have been identified and require follow up detailed work.
WCB can obtain up to a 70% interest in EL1747 Misima by spending a total of AUD$9.0M within a 4 year timeframe subject to standard regulatory approvals. Further details of this announcement and further technical information regarding Misima Island and EL1747, can be located at www.wcbresources.com/news-releases/.
