BGM EXPANDS MINERALIZATION BY 175 METERS AT ISLAND MOUNTAIN
.
Barkerville Gold Mines Ltd. {TSX.V: BGM} has provided the new drilling results from the 2019 Island Mountain exploration and category conversion program at the Company’s flagship Cariboo Gold Project in central British Columbia.
.
In January 2019, BGM commenced diamond drilling with five diamond drill rigs on Island Mountain Shaft Zone and Mosquito Creek deposits to investigate down dip extensions on the mineralized vein corridors as well as shallow infill high-grade zones. New results include 19.34 g/t Au over 17.9 meters in IM-19-013, extending a mineralized vein corridor on Shaft Zone 70 meters down dip. The current mineralization on Mosquito Creek is modelled to a depth of 200 meters and recent high-grade intercepts include 10.65 g/t Au over 4.2 meters in IM-19-004 at a depth of 375 meters from surface. These results, as well as the highlights summarized below, demonstrate continuity of grade and widths within the modelled vein corridors, expansion of mineralisation at depth and anomalous mineralization between the vein corridors.
.
Select Drilling Highlights :
IM-19-004 is located at Mosquito Creek and intersected 10.65 g/t Au over 4.2 meters which extended the mineralization at Mosquito Creek from 200 meters to 375 meters. This is one of the deepest holes at Mosquito Creek to date.
.
IM-19-007 was designed to test for new vein corridors within the sandstone along strike of the Shaft Zone to the north west. IM-19-007 assayed 10.06 g/t Au over 13.15 meters and is 20 meters from surface.
.
IM-19-010 intersected a mineralised zone of fine disseminated pyrite within silica sericite alteration adjacent to the Mosquito Fault and modelled vein corridors. IM-19-010 assayed 1.25 g/t Au over 33.25 meters. A sample within this zone assayed 9.57 g/t Au over 1.5 meters. This mineralisation is hosted in calcareous sandstone between the vein corridors and is 120 meters down plunge of IM-18-102 that assayed 1.35 g /t Au over 32.8 meters (a sample in this zone assayed 20.1 g/t over 0.5 meter) and 60 meters down plunge of hole IM-18-155 that assayed 1.32 g/t over 45.2 meters (a sample within this zone assayed 8.89 g/t Au over 1.25 meters). Mineralisation between vein corridors will significantly reduce mining dilution.
.
IM-19-012 is located at Shaft Zone and intersected previously unmodelled quartz vein mineralisation that assayed 7.02 g/t Au over 10.25 meters.
.
IM-19-013 intersected three zones of mineralisation. At 92 meters down hole, IM-19-013 intersected 26.24 g/t Au over 2.4 meters meters infilling a vein corridor. Further down hole, IM-19-013 intersected quartz veins with pyrite mineralisation that assayed 19.34 g/t Au over 17.9 meters including a sample that assayed 151.5 g/t Au over 0.50 meter and extended a modelled vein corridor 70 meters down dip. At 442 meters down hole, 350 meters from surface, this hole intersected 15.78 g/t Au over 5.35 meters, approximately 160 meters down dip of the nearest modelled vein corridor. Visible gold was observed in this hole.
.
True widths are estimated to be 50 to 75% of reported core length intervals. Intervals not recovered by drilling were assigned zero grade. Top cuts have not been applied to high grade assays.
.
A complete table of assay highlights for IM-19-001 to IM-19-015 is present below. The Shaft Zone 3D deposit model with assay highlights is located on the Company’s website:

Barkerville Gold Mines Ltd. 3D Deposit Model
Mineralized quartz veins on the Cariboo Gold Project are overall sub-vertical dip and northeast strike. Vein corridors are defined as a high-density network of mineralized quartz veins within the sandstones. These corridors have been defined from surface to a vertical depth averaging 300 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.
.
Chris Lodder, President and CEO, comments, “again these drill results demonstrate the high probability to add significant resources below our present resources within the mineralized vein corridors on Island Mountain as well as connect the Shaft and Mosquito Creek zones”.

Qualified Persons
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.
.
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 pulverised. 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-analysed using a 1,000g screen metallic fire assay. A selected number of samples are also analysed 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).
