BARKERVILLE GOLD INTERSECTS 7.75 G/T GOLD OVER 46.0 METERS AND EXTENDS DEPTH OF MINERALIZATION 250 METERS AT SHAFT ZONE
Barkerville Gold Mines Ltd. has released the final drilling results from the 2018 Island Mountain exploration and category conversion program at the company's flagship Cariboo gold project and recent results from holes drilled for metallurgical testing.
Recent highlights from the Island Mountain Shaft zone exploration and delineation program include 9.72 grams per tonne gold over 14.4 metres in hole IM-18-169 located 15 metres from surface within a modelled vein corridor. Drill hole IM-18-176 intersected 32.44 g/t Au over 3.0 metres with a higher-grade intercept 97.80 g/t Au over 0.50 metre. These results, as well as the highlights listed below, demonstrate grade and widths within the modelled vein corridors amenable to successful resource conversion.
Recent intercepts at 600 m depth include 16.10 g/t Au over 0.55 metre and 14.05 g/t Au over 0.55 metre in hole IM-18-176. The current resource at Shaft zone deposit is modelled to an average depth of 350 metres. Barkerville is currently exploring downdip of the known gold mineralization on Shaft zone with three drill rigs. Barkerville is currently exploring on Mosquito Creek with two rigs, and testing targets on Barkerville Mountain, Williams Creek and Willow with an additional three rigs. See company news release dated
Jan. 17, 2019,
for additional information on the 2019 drill program.
In addition to the delineation drilling, the company drilled a total of 11 holes on Shaft zone and Cow Mountain in mineralized vein corridors to collect material for metallurgical testing purposes. The selected assay highlights are presented below and include 7.75 g/t Au over 46.0 metres within hole IM-MET-18-002.
Selected drilling highlights:
- IM-18-162: 14.55 g/t Au over 3.65 metres;
- IM-18-164: 34.90 g/t Au over 1.45 metres;
- IM-18-169: 9.72 g/t Au over 14.40 metres;
- IM-18-173: 24.97 g/t Au over 2.50 metres;
- IM-18-174: 9.01 g/t Au over 5.50 metres;
- IM-18-176: 32.44 g/t Au over 3.00 metres including 97.80 g/t Au over 0.50 metre;
- IM-18-176: 105.0 g/t Au over 0.65 metre;
- IM-MET-18-001: 63.63 g/t Au over 1.25 metres;
- IM-MET-18-001: 142.5 g/t Au over 0.50 metre;
- IM-MET-18-002: 7.75 g/t Au over 46.0 metres;
- IM-MET-18-003: 42.10 g/t Au over 1.20 metres;
- IM-MET-18-003: 110.5 g/t Au over 1.00 metre;
- IM-MET-18-004: 34.61 g/t Au over 5.00 metres including 137.5 g/t Au over 0.85 metre;
- CM-MET-18-001: 5.78 g/t Au over 8.25 metres.
True widths are estimated to be 50 to 75 per cent 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 drill hole location plan map and section are presented on the company's website. Detailed drilling results are presented at the end of this release. The Shaft zone 3-D deposit model with assay highlights is located on the company's website.
Mineralized quartz veins on the Cariboo gold project are overall subvertical 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 metres 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 chief executive officer, commented: "These drill results demonstrate the high probability to add significant resources to at least double the depth of our average depth of present resources. This year's drilling will continue to explore these areas to a depth of up to 650 m and extensions for two km to the northwest and four km to the southeast of the defined underground resources."
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, PGeo, 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 (Canadian Institute of Mining, Metallurgy and Petroleum) 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, B.C. Numbered security tags are applied to lab shipments for chain of custody requirements. The company inserts quality control samples at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance. The QA/QC program was designed and approved by Lynda Bloom, PGeo, of Analytical Solutions Ltd., and is overseen by Ms. Layman.
Drill core samples are submitted to ALS Geochemistry's analytical facility in North Vancouver, B.C., 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 are pulverized. Analysis for gold is by 50 g fire assay fusion with atomic absorption (AAS) finish with a lower limit of 0.01 part per million and upper limit of 100 ppm. Samples with gold assays greater than 100 ppm are reanalyzed using a 1,000 g screen metallic fire assay. A selected number of samples are also analyzed using a 48-multilemental geochemical package by a four-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 hardrock mines, making it one of the most well-endowed land packages in British Columbia.
