BGM intersects 23.86 g/t Au over 6.65 meters at Shaft Zone 12.16 g/t Au over 13.30 meter intersected at depth

2018-02-21 / @newswire

 

TORONTO, Feb. 21, 2018 /CNW/ - Barkerville Gold Mines Ltd. (TSXV: BGM) (the "Company" or "Barkerville") is pleased to announce additional drilling results from the 2017 Phase II Island Mountain exploration and infill drilling program at the Company's flagship Cariboo Gold Project. The Company is currently exploring and delineating the Shaft Zone with seven drill rigs. Detailed drilling results, a drill hole location plan map and vertical sections are presented at the end of this release. The exact geometry and hence true width of the mineralized zones cannot be assuredly concluded at this time therefore core lengths are reported.

Drilling Highlights

  • IM-17-201: 104.5 g/t Au over 1.00 meter
  • IM-17-215: 23.86 g/t Au over 6.65 meters
  • IM-17-215: 12.16 g/t Au over 13.30 meters
  • IM-17-226: 28.73 g/t Au over 4.45 meters
  • IM-17-231: 24.76 g/t Au over 5.10 meters

The Company is pleased to report new mineralization expansion from the ongoing drilling at Island Mountain. Phase II drillhole IM-17-201 intersected 104.5 g/t Au over 1.00 meters at a vertical depth of 10 meters from surface. This new intersection is 40 meters up dip from previously modelled vein corridor, therefore potentially extending this vein corridor near surface.  

IM-17-215 intersected 23.86 g/t over 6.65 meters at a vertical depth of 400 meters from surface and, further down hole, intersected 12.16 g/t Au over 13.30 meters at a vertical depth of 570 meters from surface, demonstrating wide corridors at depth. IM-17-215 represents one of the deepest intercepts to date, drilling at these depths are widely spaced and untested at depth. Additional drilling is warranted to expand this mineralization.

Shaft Zone - Corridors Discussion

Mineralized quartz veins at the Shaft Zone on Island Mountain are hosted within the sandstones and are an anastomosing network of high vein density with an overall sub-vertical dip and northeast strike. Recent modelling of veins at Shaft Zone proposes 50 mineralized vein corridors with an estimated horizontal width of 3 meters and a strike length of up to 300 meters. These corridors, as well as others that are developing in the Shaft and Valley Zones have been defined from surface to a vertical depth of 600 meters and remain open for expansion to depth and down plunge. Drillhole spacing in the corridors currently averages 25 meters between drilling sections with vertical drilling separations ranging from 20 to 75 meters with hole spacing increasing at depth. 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 Exploration Manager, Maggie Layman, 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 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., and is overseen by the Company's Qualified Person, Paul Geddes, P.Geo, Vice President Exploration.

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 land package located in the historical Cariboo Mining District of central British Columbia. Barkerville's mineral tenures cover 1,950 square kilometres along a strike length of 67 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 Barkerville 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 2015 with 91,489 tonnes of material milled producing 25,464 ounces of gold. The Company has completed several drilling and exploration programs over the past 20 years and has compiled this data with all historical information in order develop geologic models which are assisting management in defining new deposits in the Cariboo Gold Project. An extensive drill program is currently underway with the goal of delineating additional high grade gold mineralization.
