Barkerville Gold Mines Ltd. is pleased to announce drilling results from the ongoing 2018 Cow Mountain exploration and category conversion program at the Company’s flagship Cariboo Gold Project. The drilling results demonstrate continuity of high grade gold mineralization within vein corridors. The Company is currently exploring and delineating high grade vein corridors with four diamond drills on Cow Mountain.

The ongoing drill program at Cow Mountain is designed to infill and expand high-grade gold-mineralized vein corridors modelled in the May 2018 Cow Mountain resource estimate. 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 300 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.
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).
