BARKERVILLE GOLD MINES REPORTS WHOLE HOLE METALLIC SCREEN FIRE ASSAY RESULTS OF THIRTY SEVEN DIAMOND DRILL HOLES CONDUCTED ON COW MOUNTAIN
Barkerville Gold Mines Ltd. has provided results from complete hole metallic screen fire assay results of 37 diamond drill holes conducted on Cow Mountain in 2011.
As recommended in the company's NI 43-101 report dated Dec. 31, 2012 (see news release dated June 19, 2013), and mentioned in the news release dated Dec. 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-gram metallic screen 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 have 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.
Metallic screen fire assay results of 37 drill holes have been received and significant intercepts are listed in the attached table. Highlights include the following.

All the significant intercepts in CM11 drill holes described above and in the table may not be the true width. Due to the complexity of analyzing three types of quartz veins; namely, strike, diagonal and orthogonal veins, the true width will be determined after the company's 3-D 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 and 2011 have 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 British Columbia. 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, for analysis. Sample preparation and geochemical assaying are done at ACME, following its own internal standards for quality control and verification. The gold assaying method uses a 1,000-gram metallic screen gold assay and 50 g lead collection fire assay. ACME is certified under the Assayers Certification Program of B.C.
