Barkerville Gold Mines Ltd. announced additional drilling results from the 2017 Phase II Island Mountain exploration and infill drilling program at the company's Cariboo Gold Project. The company is currently exploring and delineating the Shaft Zone with seven drill rigs. Detailed drilling results, a drill hole location plan map and vertical sections are presented at the end of this release. The exact geometry and hence true width of the mineralized zones cannot be assuredly concluded at this time therefore core lengths. Drilling Highlights: IM-17-217: 7.28 g/t Au over 12.50 meters. IM-17-217: 16.67 g/t Au over 5.20 meters. IM-17-219: 12.40 g/t Au over 7.00 meters. IM-17-223: 11.15 g/t Au over 7.30 meters. IM-17-224: 8.71 g/t Au over 3.00 meters. The company reported new mineralization expansion from the ongoing drilling at Island Mountain. Phase II drillhole IM-17-219 intersected 12.40 g/t Au over 7.00 meters at a vertical depth of 280 meters from surface. This new intersection is 135 meters down dip from previously reported hole IM-17-016 that assayed 5.62 g/t Au over 11.40 meters and 12.27 g/t Au over 7.45 meters. These correlating intercepts are a potential new vein corridor at Island Mountain. Additional drill highlights include 7.28 g/t Au over 12.50 meters intersected in IM-17-217 at a vertical depth of 400 meters from surface, demonstrating wide corridors of mineralization at depth in the Shaft Zone. Drilling below 300 vertical meters is widely spaced in this area and additional drilling is warranted to expand known mineralization at depth. Shaft Zone - Corridors Discussion: The sandstone hosted veining which constitutes the newly named Alpha, Beta and Gamma Corridors of the Shaft Zone are manifested as an anastomosing network of high vein density with an overall sub-vertical dip and northeast strike. Based upon drilling results to date, estimated horizontal widths of the corridors are variable and range from 5 to 35 meters. These corridors, as well as others that are developing in the Shaft and Valley Zones have been defined from surface to a vertical depth of 600 meters and remain open for expansion to depth and down plunge. Drillhole spacing in the corridors currently averages 25 meters between drilling sections with vertical drilling separations ranging from 20 to 75 meters with hole spacing increasing to depth. Gold grades are intimately associated with vein-hosted pyrite as well as pyritic, intensely silicified wall rock haloes in close proximity to the veins. Quality Assurance – Quality Control: Once received from the drill and processed, all drill core samples are sawn in half, labelled and bagged. The remaining drill core is subsequently stored on site at the Company's secure facility in Wells, BC. Numbered security tags are applied to lab shipments for chain of custody requirements. The Company inserts quality control (QC) samples at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance. The QAQC program was designed and approved by Lynda Bloom, P.Geo. of Analytical Solutions Ltd., and is overseen by the Company's Qualified Person, Paul Geddes, P.Geo, Vice President Exploration. Drill core samples are submitted to ALS Geochemistry's analytical facility in North Vancouver, British Columbia for preparation and analysis. The ALS facility is accredited to the ISO/IEC 17025 standard for gold assays and all analytical methods include quality control materials at set frequencies with established data acceptance criteria. The entire sample is crushed and 250 grams is pulverized. Analysis for gold is by 50g fire assay fusion with atomic absorption (AAS) finish with a lower limit of 0.01 ppm and upper limit of 100 ppm. Samples with gold assays greater than 100 ppm are re-analyzed using a 1,000g screen metallic fire assay. A selected number of samples are also analyzed using a 48 multi-elemental geochemical package by a 4-acid digestion, followed by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS).
