Barkerville Gold Mines Ltd. announce the updated underground resource estimate for Cow, Island and Barkerville Mountain deposits at its 100% owned Cariboo Gold Project located in Wells, B.C. The mineral resource estimate incorporates the Cow and Valley Zones on Cow Mountain, Shaft and MosquitoCreek Zones on Island Mountain and BC Vein and Bonanza Ledge on Barkerville Mountain at a cut-off grade of 3.0 g/t Au ("grams per metric tonne"). The resource is defined over 6 kilometers of BGM's 67-kilometer-long land package. Infill and exploration drilling are ongoing on the property. The mineral resource estimate was conducted by Talisker Exploration Services Inc. under the supervision of InnovExplo Inc. The mineral resource estimate for Cow and Island Mountain deposits is built upon over 400,000 meters from BGM's 2015 to 2018 drill campaigns, and historically verified drill data using a total of 3,426 drillholes. A strong understanding of the controls of mineralization enabled the Company's technical team to construct a mineral resource estimate constrained by lithology, alteration, structure and mineralization. The mineral resource estimate is supported by a robust 3D litho-structural model of the gold-bearing vein corridors. The 2018 exploration and category conversion drill program was successful in improving the precision of vein corridors; a total of 249 vein corridor solids were individually modelled. Average dimensions of a vein corridor are 300 meters by 300 meters by 3 meters with thickness of the vein corridors ranging from 2 meters to 40 meters. The resource estimate includes the internal dilution of the sandstone host within the vein corridors. The vein corridors are modelled to an average depth of 350 meters, exploration drilling has intersected mineralization at depths below 700 meters from surface. BGM is currently drilling down dip and along strike of mineralized vein corridors to define additional resources at Cow and Island Mountain. BGM intends to drill from underground infrastructure once permitting and construction of an exploration drift is complete. The robust 3D litho-structural model that defines the controls of mineralization allows the exploration team to define additional mineral resource much more efficiently, lowering the cost per discoverable ounce. This model can be applied to the remaining 65 kilometers of strike. In accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101"), an updated technical report for the Cariboo Gold Project will be filed on SEDAR and the Company's website within 45 calendar days of this disclosure.
