BGM Intersects 17.30 G/T Au Over 7.50 Metres at Valley Zone

Expansion of Vein Corridors Continues

TORONTO, July 5, 2017 /CNW/ - Barkerville Gold Mines Ltd. (TSXV: BGM) (the "Company" or "Barkerville") is pleased to announce additional drilling results from the ongoing 130,000 metre Phase II Island Mountain exploration drilling program at the Company's flagship Cariboo Gold Project. The Company is currently exploring and delineating the Valley and Shaft Zones with seven drill rigs, while an eighth drill rig is conducting exploratory drilling on Barkerville Mountain. Detailed drilling results, a drill hole location plan map, vertical section and longitudinal section are presented at the end of this release.

Veining Corridors Continue to Develop in Valley Zone

The ongoing exploration and delineation drilling program in the Valley Zone continues to corroborate veining corridors as demonstrated by drillhole CM-17-057 which intersected a broad network of veining averaging 17.30 g/t Au over 7.50 metres at vertical depth of 170 metres below surface. At the same elevation 130 metres along vein strike to the southwest, drillhole CM-17-048 delineated additional veining grading 12.27 g/t Au over 4.55 metres. In a previously unexplored portion of the Valley Zone, another new veining occurrence averaging 11.33 g/t Au over 3.00 metres was discovered by drillhole CM-17-053 at a vertical depth of 140 metres below surface. Because of the wide hole spacings and scarcity of historical drilling in these areas, all occurrences are open for expansion.

"The high-grade vein corridors in the Valley Zone continue to be identified and will require infill drilling later in the year." noted Chris Lodder, President and CEO of Barkerville Gold Mines. "Seven drills are focused on infill drilling on Island Mountain and one rig is conducting reconnaissance drilling on Barkerville Mountain. Regional exploration in the larger land package was reinitiated last week and will continue until late September. The objective of the regional exploration program is to continue the advancement of future drill targets. Underground mine development continues at Bonanza Ledge with processing at the QR mill to start in August."

Qualified Persons

Exploration activities at the Cariboo Gold Project are administered on site by the Company's Exploration Manager, Maggie Layman, P.Geo. As per National Instrument 43-101 Standards of Disclosure for Mineral Projects, Paul Geddes, 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, Paul Geddes, 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).

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 historic Barkerville Gold Mining Camp near the town of Wells, British Columbia. The QR Project, located approximately 110 kilometres by highway and all weather road from Wells was acquired by Barkerville in 2010 and boasts a fully permitted 900 tonne/day gold milling and tailings facility. Test mining of the Bonanza Ledge open pit was completed in March of 2015 with 91,489 tonnes of material milled producing 25,464 ounces of gold. The Company has completed several drilling and exploration programs over the past 20 years and has compiled this data with all historical information in order develop geologic models which are assisting management in defining new deposits in the Cariboo Gold Project. An extensive drill program is currently underway with the goal of delineating additional high grade gold mineralization.
