BGM EXPANDS MINERALIZATION AT DEPTH WITH 45.94 G/T GOLD OVER 5.2 METERS ON ISLAND MOUNTAIN
Barkerville Gold Mines Ltd. has provided 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.
New results from 24 recent holes on Island Mountain include 45.94 g/t Au over 5.2 meters including a sample of 399 g/t Au over 0.50 meter in exploration hole IM-19-043 located on the Island Mountain Mosquito Creek deposit and 95 meters down plunge from an existing vein corridor. Infill hole IM-19-029 intersected multiple vein corridors at Shaft Zone that assayed 14.91 g/t Au over 4.40 meters including a sample of 55.90 g/t Au over 0.80 meters. 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.
A total of 20,000 meters in 47 holes were drilled at Shaft Zone and Mosquito Creek on Island Mountain in 2019. The program focused on infill drilling modelled vein corridors and conducting exploration along strike and down dip of existing vein corridors to determine the depth extent of the mineralization.
Select Drilling Highlights :
IM-19-029: 14.91 g/t Au over 4.40 meters including 55.9 g/t Au over 0.80 meters
IM-19-032: 31.8 g/t Au over 1.20 meters
IM-19-036: 46.8 g/t Au over 0.65 meters
IM-19-039: 61.8 g/t Au over 0.5 meters
IM-19-039: 53.3 g/t Au over 0.5meters
IM-19-039: 27.23 g/t Au over 2.15 meters
IM-19-040: 8.94 g/t Au over 6.20 meters
IM-19-040: 21.18 g/t Au over 3.20 meters including 54.1 g/t Au over 0.90 meters
IM-19-040: 7.31 g/t Au over 7.85 meters including 68.5 g/t Au over 0.5meters
IM-19-043: 45.94 g/t Au over 5.20 meters including 399 g/t Au over 0.5meters
IM-19-045: 7.75 g/t Au over 6.50 meters including 40.4 g/t Au over 0.70 meters
IM-19-047: 45.5 g/t Au over 0.65 meters
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-19-024 to IM-19-47 is present below. The Cariboo Gold Project 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 within the axis of the F3 fold and hosted 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.
Qualified Persons
Exploration activities at the Cariboo Gold Project are administered on site by the Company's Project Geologists, Kyle Orr and Felipe Castaneda. 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 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 mineral rights package located in the historical Cariboo Mining District of central British Columbia. Barkerville's Cariboo Gold Project mineral tenures cover 1,950 square kilometres; along a strike length of 67 kilometres which includes several past producing placer and hard rock mines, making it one of the most well-endowed land packages in British Columbia. Since the management change in mid-2015, the Company has unlocked the fundamental structural controls of gold mineralization. The Company's Brownfield's exploration team is focused on upgrading and expanding the May 2018 43-101 compliant resource within the 8 kilometers of principle project area located near the town of Wells, British Columbia. The Company's Greenfield's team is developing quality exploration assets throughout the remaining land package through systematic, scientific, exploration. The operation's team is focused on completing required studies in order to permit underground mining on Cow and Island Mountains.
