Barkerville Gold Mines Ltd. (TSXV: BGM. the "Company" or "BGM") is pleased to announce 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 metersand 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 mineralization 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 mineralized 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 mineralization 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). Mineralization between vein corridors will significantly reduce mining dilution.
IM-19-012 is located at Shaft Zone and intersected previously unmodelled quartz vein mineralization that assayed 7.02 g/t Au over 10.25 meters.
IM-19-013 intersected three zones of mineralization. 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 mineralization 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.
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”.
