Barkerville Gold Mines Ltd. (TSX-V: BGM) is pleased to announce drilling results from the 50,000-meter 2018 Island Mountain exploration and delineation programs at the Company’s flagship Cariboo Gold Project. Detailed drilling results, a drill hole location plan map and vertical sections are presented at the end of this release. True widths are estimated to be 50 to 75% of reported core length intervals. The Company currently has seven drill rigs exploring and delineating mineralized vein corridors on Island Mountain. An eighth drill rig is exploring regional targets 6 km south east of Barkerville Mountain.
Vein Zone Continuity on Island Mountain
The 2018 drill program at Island Mountain is designed to infill and expand known vein corridors on the property. Continuity and extensions of mineralized vein corridors on Island Mountain is demonstrated from recent results. Island Mountain hole IM-18-006 intersected 24.16 g/t Au over 14.55 meters, 140 meters up dip of IM-18-019 that assayed 11.35 g/t Au over 6.30 meters. These intercepts are within and adjacent to modelled vein corridors. IM-18-005 intersected 14.69 g/t Au over 15.80 meters, 35 meters up dip from a modelled vein corridor and IM-18-010 that assayed 19.64 g/t Au over 3.85 meters.
Mineralized quartz veins on the Cariboo Gold Project are hosted within the sandstones and are an anastomosing network of high vein density with an overall sub-vertical dip and northeast strike. Recent modelling of the vein corridors Island Mountain proposes 64 mineralized vein corridors. These vein corridors have estimated horizontal width of 3 meters and a strike length of up to 300 meters. These corridors have been defined from surface to a vertical depth of 600 meters and remain open for expansion at depth and down plunge. Drill hole 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 at 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.
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.
