INFILL DRILLING CONFIRMS HIGH-GRADE GOLD MINERALIZATION BGM INTERSECTS 12.54 G/T AU OVER 18.20 METERS ON ISLAND MOUNTAIN TORONTO, ON – May 8, 2018 –
Barkerville Gold Mines Ltd. (TSXV: BGM) (the “
Company” or “
Barkerville”) is pleased to announce additional drilling results from the 50,000-meter 2018 Island Mountain exploration and delineation program 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. The infill drilling results continue to demonstrate continuity and expansion of modelled vein corridors.

- IM-18-023: 54.51 g/t over 1.75 meters
- IM-18-023: 73.8 g/t over 1.25 meters
- IM-18-033: 16.96 g/t over 9.30 meters
- IM-18-038: 12.54 g/t over 18.2 meters
- IM-18-038: 17.91 g/t over 5.65 meters
- IM-18-039: 22.87 g/t over 5.85 meters
- IM-18-041: 36.41 g/t over 4.30 meters
- IM-18-046: 27.41 g/t over 4.35 meters
Vein Zone Continuity on Island Mountain The intervals noted above were intersected in holes designed to infill and expand known vein corridors on the property down to depths of 500 meters. The program consisted of 50,000 meters drilled in 162 holes, mainly in the Shaft Zone area. 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 101 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. 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 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).
