BGM INTERSECTS 18.84 G/T AU OVER 30.85 METRES AT SHAFT ZONE
Additional drilling results from the continuing 130,000-metre phase 2 Island Mountain exploration drilling program at Barkerville Gold Mines Ltd.'s flagship Cariboo gold project have confirmed short-range continuity of the vein systems and expanded a veining corridor at depth in the Shaft zone. The company is currently exploring and delineating the Valley and Shaft zones with seven drill rigs, while an eighth drill rig is testing a broad gold-in-soil anomaly on Barkerville Mountain. Given the continued drilling success at the project, the company has ordered two additional drill rigs for early August, 2017, bringing the total number of operating rigs to 10. Detailed drilling results, a drill hole location plan map, vertical section and longitudinal section are presented on the company's website.
Short-range continuity confirmed in Shaft zone
The company is very pleased to announce that phase 2 drill hole IM-17-024 has successfully demonstrated and enhanced the short-range grade continuity and width of one of the numerous Shaft zone veining corridors via the intersection of 18.84 grams per tonne gold over 30.85 metres. This intensely veined and silica-altered sandstone-hosted zone occurs 20 metres vertically below previously reported drill hole IM-17-078 which intersected 11.42 g/t Au over 28.55 metres at a vertical depth of 450 metres below surface. Because these stand-alone drill holes constitute only two intercepts that cannot be confidently corroborated by additional drill hole pierce points, the geometry and hence true width of the potential mineralized zone cannot be assuredly concluded at this time.
New Shaft zone high-tenor veining corridors intersected at depth
Approximately 19 metres downhole from the above-stated intersection a second zone grading 7.88 g/t Au over 7.70 metres was encountered followed by another high-tenor zone 55 metres more downhole in drill hole IM-17-124. This third veining corridor was intersected grading 12.76 g/t Au over 25.40 metres at a vertical depth of 540 metres below surface and is to date the deepest veining discovered in the Shaft zone. As such, this new occurrence is open for expansion and is supported by previously reported drill hole IM-17-097 which intersected analogous veining grading 40.19 g/t Au over 3.10 metres, 39.05 g/t Au over 8.25 metres and 10.34 g/t Au over 4.50 metres at vertical depth of 480 metres below surface. Drill hole IM-17-097 is located 50 metres to the east along vein strike.
Chris Lodder, president and chief executive officer, commented, "These infill drilling results and the nearby newly identified mineralized zones demonstrate the potential for large-tonnage, high-grade mineralized corridors which may be amenable to larger-tonnage underground mining methods."
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 standards of disclosure for mineral projects, Paul Geddes, PGeo, 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 (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, Mr. Geddes.
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 spectroscopy (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-gram screen metallic fire assay. A selected number of 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 hard-rock 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.

True widths cannot be accurately determined from the information available
therefore core lengths are reported. Rock not recovered by drilling was
assigned zero grade. Top cuts have not been applied to high-grade assays.
