Resource Update on Cow Mountain to Commence
Vancouver, British Columbia / TNW-ACCESSWIRE / July 18 2014 / Barkerville Gold Mines Ltd. ("Barkerville" or the "Company") is pleased to announce today it has completed the infill and reject assaying program of the diamond drill hole database on Cow Mountain. With the completion of this program, the Company intends to commission an update to its NI 43-101 Technical Report ("Technical Report") dated December 31, 2012, which will include an update to the Cow Mountain mineral resource estimate.
The updated diamond drill hole database contains 26,728 drill core samples in total including (Table 1):
-11,611 infill drill core samples that were previously unassayed and not utilized in the Technical Report, of which 5,298 samples were analyzed for metallic screen fire assays and 6,313 samples analyzed for lead collection/gravimetric assays.
-15,117 original samples with standard fire assays that were utilized in the calculation of the Technical Report. Over approximately the past 18 months, 14,452 reject samples of the 15,117 original samples were analyzed for metallic screen fire assays.
These drill core samples were collected from 258 diamond drill holes (including 14 twinned holes) conducted in 2007, 2009, 2010, 2011 and 2012 and do not include abandoned drill holes.
Assaying of both the reject and infill core samples were done by ACME Analytical Laboratories Ltd. in Richmond and SGS Canada Inc. in Burnaby, BC, Canada.
As recommended in the Technical Report (see News Releases dated June 19 2013 and December 9, 2013), all available reject samples from drill core that was originally analyzed before 2012 with standard fire assays and unassayed infill core samples from those same holes collected in 2013, have been sent for 500/1,000 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.

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 500 - 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 244 Cow Mt. drill holes conducted in 2007, 2009, 2010 & 2011 started in 2013 was completed in the beginning of 2014. News on complete holes that included metallic screen fire assay results of reject samples and lead collection fire assay results of previously unassayed infill core samples were published as they became available (please see news releases dated May 01 & 22, March 24, February 12, 2014, and December 16, 2013). In early July 2014, the Company completed the update of new assay results which are currently being compiled in a format to be published in a news release shortly.
The Company intends to retain an independent consultant to complete a comparative analysis between new and original drill data which will be utilized in the updated NI 43-101 resource estimate on Cow Mountain.
The technical information contained in this news release has been reviewed and approved by the Company's Chief Geologist Jim Yin, Ph.D., a Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Project.
