COW MOUNTAIN DRILLING INTERSECTS HIGH GRADE GOLD MINERALIZATION
Barkerville Gold Mines Ltd. has released drilling results from the continuing 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.
Selected drilling highlights

Detailed drilling results are presented in the table. The Cow Mountain 3-D deposit model with assay highlights is located on the company's website.
The continuing 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 subvertical dip and northeast strike. These corridors have been defined from surface to a vertical depth of up to 300 metres 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.
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, Maggie Layman, PGeo, vice-president of 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 Canadian Institute of Mining, Metallurgy and Petroleum 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, B.C. Numbered security tags are applied to lab shipments for chain of custody requirements. The company inserts quality control samples at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance. The QA/QC program was designed and approved by Lynda Bloom, PGeo, of Analytical Solutions Ltd., and is overseen by Ms. Layman.
Drill core samples are submitted to ALS Geochemistry's analytical facility in North Vancouver, B.C., 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 are pulverized. Analysis for gold is by 50 g fire assay fusion with atomic absorption (AAS) finish with a lower limit of 0.01 part per million and upper limit of 100 ppm. Samples with gold assays greater than 100 ppm are reanalyzed using a 1,000 g screen metallic fire assay. A selected number of samples are also analyzed using a 48-multilemental geochemical package by a four-acid digestion, followed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and inductively coupled plasma mass spectroscopy (ICP-MS).
