Phase 1 drilling results extends mineralization and identifies new gold target at Cariboo Project. Results include 18.4 g/t over 3.35 m
VANCOUVER, BC / TheNewswire / August 12, 2015 - Barkerville Gold Mines Ltd. (TSXV: BGM) (the "Company" or "BGM") today announced results from the ongoing Phase I drilling program on Barkerville Mountain at the Company's flagship Cariboo Gold Project ("CGP") that identified a new exploration target and significantly improved the Company's understanding of the BC Vein and the TC Area mineralization.
Holes BGM-15-005 through BGM-15-007 were designed to explore the footwall rocks below the BC Vein ("BCV"), an area which had its geometry and gold grades validated during the Company's first drill results (see BGM News Release dated July 28, 2015), for the presence of Bonanza Ledge ("BL") style replacement mineralization. Holes BGM-15-008 through BGM-15-013 tested a mineralized occurrence (TC Area) located approximately 100 metres north of the Bonanza Ledge open pit. Table 1 (below), presents the results from these drillholes which totaled 1,524 metres.
"We are encouraged by these most recent results from our ongoing program," said Tom Obradovich, President and CEO of the Company. "In addition to finding mineralization in each of the holes, we gained valuable information about the style and extent of that mineralization. This data will be extremely valuable in establishing a geological model for the property and, ultimately, a development strategy."

Notes:
Core lengths represent 70-90% true widths. Rock not recovered by drilling was assigned zero grade and not included in the composites. Top cuts have not been applied to high grade assays. 1.0 ounces = 34.285 grams. BCV - BC Vein; HWV - Hanging Wall Vein.
Discussion of Results
Drillholes BGM-15-005 through BGM-15-007 tested the BLHorizon ~300 metres northwest of the BL open pit. Although no significant mineralization was intersected in this select area of the horizon, a near surface, previously undrilled hangingwall vein (HWV) set was encountered at the top of these holes and represents a new exploration target.

The TC Area was targeted by BGM-15-008 through BGM-15-013 and is located ~100 metres north of the BL open pit. The TC mineralization had very limited drilling performed in 2011 by previous operators, and is now defined by 2015 Phase I drilling as a series of sulphide bearing quartz veins striking at an oblique angle to the BCV. Further drilling for both of these areas is being planned to determine the extents of the mineralization.

Additional Diamond Drill Rigs Ordered
Two additional drill rigs have been ordered from Geotech Drilling Services Limited and are expected to arrive on the project site by the end of August 2015. These drill rigs will be employed on Barkerville Mountain with the ultimate goal of drill defining the BCV to a vertical depth of -400 metres as well as testing previously undrilled targets.
New Drilling Practices and Core Recovery
During the preliminary stages of the 2015 Phase I drilling campaign, it was observed that portions of the mineralized zones were not recovered by the drilling process. These intervals of lost core have been assigned zero gold grade. It has been ascertained that the high sulphide intervals were essentially "washed away" by the drilling process and hence not recovered in their entirety. In consultation with Geotech Drilling Services Limited, an industry standard, environmentally safe drilling additive is now being utilized in all holes and core recoveries have increased to greater than 95% through the mineralized sulphide zones.
Qualified Persons
Exploration activities at the Cariboo Gold Project are jointly administered on site by the Company's Project Managers Maggie Layman, P.Geo. and Wanda Carter, 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 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 byPaul Geddes, P.Geo, Vice President Exploration.
Drill core samples are submitted to SGS Canada's analytical facility in Burnaby, B.C. for preparation and analysis. The SGS 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 1,000 grams is pulverized. Analysis for gold is by 50g fire assay fusion with atomic absorption (AAS) finish with a lower limit of 5ppb and upper limit of 10,000ppb. Samples with gold assays greater than 10,000ppb are re-analyzed using 50g fire assay with gravimetric finish, as well as 1,000g screen metallic fire assay. Samples are also analyzed using a 49 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 BGM
The company is focused on developing its extensive land package located in the historical Cariboo Mining District of central British Columbia. BGM's mineral tenures cover 1,164 square kilometres along a strike length of 60 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 BGM 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 this year with 91,489 tonnes of ore milled producing 25,464 ounces of gold. BGM has completed a number of drilling and exploration programs over the past 20 years and is currently compiling this data with all historical information in order develop geologic models which will assist new management and provide the framework to continue to explore the Cariboo Gold Project. An extensive drill program is currently underway with the goal of delineating additional high grade gold mineralization.
