Barkerville Gold Mines Reports Metallic Screen Fire Assay Results of Seven Diamond Drill Holes Conducted on Cow Mt. in 2011, Including 57.4 feet of 3.057 oz/t Gold

 

 

 

 

 

 

Barkerville Gold Mines Ltd. (TSXV: BGM) announced today results from its complete hole metallic screen fire assay program from seven diamond drill holes conducted on Cow Mt. in 2011. As recommended in the Company’s NI 43-101 Technical Report dated December 31, 2012 and mentioned in the Company’s news release dated December 9, 2013, all reject samples with standard fire assays completed in 2011 and infill core samples collected in 2013 have been sent to the assay lab for 500-1,000 gram metallic screen fire assaying.

 

Results from the first seven complete drill holes have been received thus far and significant intercepts are listed in Table 1. Highlights include:

All intercepts described may not be the true widths. Due to the complexity and mixture of three types of quartz veins; namely, strike, diagonal & orthogonal veins, true widths won’t be available until the 3D geological model is updated.

 

The standard fire assay technique was originally conducted on a relatively small (30 gram) aliquot of sample material that may or may not have been truly representative of the gold content of the sample as a whole. This can particularly be the case if coarse gold or visible gold was present, which is notoriously difficult to homogenize within a sample pulp. The Screen Metallic technique utilized in the Company’s Double Assay Program effectively evaluates 500 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.

 

Reject sampling, infill core sampling and core sample cutting and/or assaying representing complete holes from 128 of 239 Cow Mountain drill holes conducted between 2007-2011 continues. The sampling and cutting is expected to be completed in January, 2014. News highlighting additional complete holes from the metallic screen assay program will be published when available.

 

A reject fraction or sample is generally the coarse crushed portion of a sample that remains after a split of the sample has been removed for fine crushing (pulverizing) and for analysis including fire assay. The coarse crush reject is the unassayed portion of the sample that was not pulverized for analysis and the word reject does not reflect quality but rather that portion of the sample not used to prepare for analysis. It is a common practice that when high grade or coarse gold is found to be present, a metallic screen fire assay is performed on the coarse reject material utilizing higher subsample weight of 500 to 1000 grams of material, as opposed to 30 grams used in a conventional fire assay.

 

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 Inspectorate Exploration & Services Ltd. in Richmond, B.C. and ACME Analytical Laboratories Ltd. in Vancouver, B.C., both of which are Bureau Veritas Group companies, for analysis. Sample preparation and geochemical assaying is done at ACME and Inspectorate Labs respectively, following their own internal standards for quality control and verification. The gold assaying method uses a 500 and 1,000 grams metallic screen gold assay. Both ACME and Inspectorate are certified under the Assayers Certification Program of B.C.

The Company’s mineral tenures cover 1,164 km2 along a strike length of 60 km and approximate width of 20 km, including the Cariboo Gold Project, the Bonanza Ledge Gold Project, the Barkerville Mountain and Island Mountain exploration targets and seven past producing hard rock mines. The QR Property was acquired in February 2010 and includes a 900 tonne/day gold milling facility and a permitted gold mine located approximately 110 km by highway and all-weather road from the Barkerville Gold Camp. In November 2010, the Company acquired a second permitted mill currently on care and maintenance in Revelstoke, B.C. The Company has completed significant drilling and exploration programs and, together with the historical data, is compiling all information to determine the geologic models and updated technical reports to continue with exploration and development of the Cariboo Gold projects. This news release has been prepared on behalf of the Board of Directors of the Company which takes full responsibility for its contents.
