BARKERVILLE GOLD MINES: INFILL DRILLING CONFIRMS HIGH-GRADE GOLD MINERALIZATION
Barkerville Gold Mines Ltd. has released additional drilling results from the 50,000-metre 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 on the company's website. The infill drilling results continue to demonstrate continuity and expansion of modelled vein corridors.
Drilling highlights:
-
IM-18-023: 42.20 grams per tonne gold over 2.00 metres;
-
IM-18-023: 54.51 g/t Au over 1.75 metres;
-
IM-18-023: 73.8 g/t Au over 1.25 metres;
-
IM-18-033: 16.96 g/t Au over 9.30 metres;
-
IM-18-038: 12.54 g/t Au over 18.2 metres;
-
IM-18-038: 17.91 g/t Au over 5.65 metres;
-
IM-18-039: 22.87 g/t Au over 5.85 metres;
-
IM-18-041: 36.41 g/t Au over 4.30 metres;
-
IM-18-046: 27.41 g/t Au over 4.35 metres.
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 metres. The program consisted of 50,000 metres 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 subvertical 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 three metres and a strike length of up to 300 metres. These corridors have been defined from surface to a vertical depth of 600 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 exploration manager, Maggie Layman, PGeo. As per National Instrument 43-101, Paul Geddes, 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 (QC) 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 the company's qualified person, 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-gram 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. Selected samples are also analyzed using a 48-multielemental 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).
About Barkerville Gold Mines Ltd.
The company is focused on developing its extensive land package located in the historical Cariboo mining district of central British Columbia. Barkerville's mineral tenures cover 2,110 square kilometres along a strike length of 67 kilometres, which includes several past-producing hardrock mines of the historical Barkerville gold mining camp near the town of Wells, B.C. An extensive drill program is currently under way with the goal of delineating additional high-grade gold mineralization.

assigned zero grade. Top cuts have not been applied to high-grade
assays.
