42.61 G/T GOLD OVER 7.05 METERS AT MOSQUITO CREEK ZONE AND
20.27 G/T GOLD OVER 4.20 METERS AT SHAFT ZONE

TORONTO, Sept. 13, 2018 /CNW/ - Barkerville Gold Mines Ltd. (TSXV: BGM) (the "Company" or "Barkerville") is pleased to announce final drilling results from the 50,000-meter 2018 Island Mountain exploration and delineation program at the Company's flagship Cariboo Gold Project. The infill drilling results continue to expand known vein corridors at depth and demonstrate continuity at both Shaft Zone and Mosquito Creek Zone on Island Mountain.

Recent highlights include high-grade intersections at Mosquito Creek Zone hole IM-18-146 that assayed 42.61 g/t Au over 7.05 meters at a vertical depth of 130 meters. This intercept is 50 meters down dip from hole IM-18-147 that assayed 11.95 g/t Au over 1.30 meters.  At Shaft Zone, hole IM-18-152 intersected 23.70 g/t Au over 3.85 meters at a vertical depth of 550 meters and includes a sample of 120.50 g/t Au over 0.65 meter. IM-18-152 is one of the deepest mineralized intercepts to date. Detailed drilling results are presented in the table below. A drill hole location plan map is presented at the end of this release. The Company's 3D  deposit model with assay highlights is located here

Selected Drilling Highlights:

  • IM-18-130: 20.27 g/t Au over 4.20 meters

Infill Program on Island Mountain Successful in Delineation Vein Corridors and Expansion at Depth

The intervals noted above were intersected in holes from both Shaft Zone and Mosquito Creek Zone on Island Mountain. The holes were designed to infill and expand mineralized vein corridors. Vein corridors are defined as a high-density network of mineralized quartz veins within the sandstones.   Mineralized quartz veins on the Cariboo Gold Project are overall sub-vertical dip and northeast strike.  These corridors have been defined from surface to a vertical depth of up to 600 meters and remain open for expansion at depth and down plunge. Gold grades are intimately associated with vein-hosted pyrite as well as pyritic, intensely silicified wall rock haloes in close proximity to the veins.

The Company is currently exploring and delineating vein corridors with six drill rigs on Cow Mountain. Results from these holes will become available in the coming weeks.

Qualified Persons

Exploration activities at the Cariboo Gold Project are administered on site by the Company's Project Geologists, Kyle Orr and Felipe Castaneda. As per National Instrument 43-101 Standards of Disclosure for Mineral Projects, Maggie Layman, P.Geo. Vice President Exploration, is the Qualified Person for the Company and has prepared, validated and approved the technical and scientific content of this news release. The Company strictly adheres to CIM Best Practices Guidelines in conducting, documenting, and reporting its exploration activities on the Cariboo Gold Project.

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, Maggie Layman, 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).

About Barkerville Gold Mines Ltd.

The Company is focused on developing its extensive mineral rights package located in the historical Cariboo Mining District of central British Columbia. Barkerville's Cariboo Gold Project mineral tenures cover 1,950 square kilometres; along a strike length of 67 kilometres which includes several past producing placer and hard rock mines, making it one of the most well-endowed land packages in British Columbia. Since the management change in mid-2015, the Company has unlocked the fundamental structural controls of gold mineralization. The Company's Brownfield's exploration team is focused on developing and delineating a mineable resource within the 7 kilometers of principle project area located near the town of Wells, British Columbia.  The Company's Greenfield's team is developing quality exploration assets throughout the remaining land package through systematic, scientific, exploration.  The operation's team is focused on developing and mining the Bonanza Ledge and BC Vein deposits on Barkerville Mountain.  This operation allows the company to generate near term cash flow, train a local work force, keeps the present mining permit active, and de-risk's the project through staged production growth.  Processing of material from these deposits is processed at the QR mill.  QR is a fully owned, permitted mill and tailings facility, located approximately 110 kilometres away from Wells, and can be accessed by an all-season road.
