Vancouver, BC / ACCESSWIRE / May 22 2014 / Barkerville Gold Mines Ltd. (TSXV: BGM) (the "Company") announced today, results from complete hole metallic screen fire with minor lead collection/gravimetric assay results of twenty one diamond drill holes conducted on Cow Mountain in 2011.
As recommended in the Company's NI 43-101 report dated December 31, 2012 (the "Technical Report", see News Release dated June 19 2013) and mentioned in the news release dated December 9, 2013, all reject samples from drill core that was originally analyzed in 2011 with standard fire assays and unassayed infill core samples from those same holes collected in 2013 have been sent for 1,000 g metallic screen and 50 g lead collection/gravimetric fire assay. Considering coarse grained gold is common in the area, it has been determined that the original 30 g standard fire assay method possibly undervalued gold grade. Once all drill data has been received, the Company will provide a comparative analysis between new and original drill data. The Company will also provide an updated NI 43-101 resource estimate.
Milling operations at the Company's QR facility have been ongoing. Updates and pictures are available for viewing on the Company's website at www.barkervillegold.com.
Metallic screen fire assay results of twenty one drill holes have been received and significant intercepts are listed in Table 1. Highlights include:

All the significant intercepts in CM11 drill holes described above and in Table 1 may not be the true width. Due to the complexity of analyzing three types of quartz veins; namely, strike, diagonal & orthogonal veins, the true width will be determined after the Company's 3D geological model is updated.
The standard fire assay technique was conducted on a relatively small (30 g) aliquot of sample material that may or may not be truly representative of the gold content of the sample as a whole, particularly if coarse gold or visible gold is present that is notoriously difficult to homogenize within a sample pulp. The Metallic Screen technique utilized in the Company's Double Assay Program effectively evaluates 1,000 grams of pulverized material for each sample and was specifically developed by laboratories to measure coarse or visible gold within pulverized sample materials to provide a more representative estimate of overall gold content.
The collection of reject samples, infill core sampling and core sample cutting of 239 Cow Mt. drill holes conducted in 2007, 2009, 2010 & 2011 has been completed. News on complete holes that include metallic screen fire assay results of reject samples and lead collection fire assay results of previously unassayed infill core samples will be published as they become available. The Company is in the process of utilizing this information to update the drill hole database.
Drill core processing included descriptive logging and sampling for geochemical analyses. The NQ-size drill core was cut/split in two halves using saws at the Company's Lowhee Creek Compound in Wells-Barkerville, central B.C. One-half of the core is put in a sample bag. After all the samples are placed in the rice bags at the mine site, they are transported by BGM's personnel to a shipping company in Quesnel for trans-shipment to ACME Analytical Laboratories Ltd. in Vancouver, which is under the Bureau Veritas Group Company, and to SGS Canada Inc. in Burnaby for analysis. Sample preparation and geochemical assaying is done at both ACME & SGS for better QA/QC, following their own internal standards for quality control and verification. The gold assaying method uses a 1,000 grams metallic screen gold assay and 50 g lead collection fire assay. Both ACME and SGS are certified under the Assayers Certification Program of B.C.
