Cow Mountain Phase I Drilling
As per the Company's directive to optimize a new, geologically constrained gold resource at Cow Mountain potentially amenable to either open pit and or underground mining methods, 242 drillholes totaling 32,290 metres have now been completed in the 2016 Phase I drilling program. Assay results for the final 40 drillholes are pending and will be made public once available. The purpose of the Cow Mountain 2016 campaign was to confirm and upgrade auriferous drill intersections by previous operators from 1938-1981 that were classified as inferred mineralization because of lessened data confidence and not simply a function of wider drillhole spacing. The 2016 Phase I program was explicitly targeting these areas by replacing the historical gold intersections with modern drilling that conforms to CIM best practices and QAQC procedures. Based upon the 2016 drilling results to date, there has been excellent correlation between the historic mineralized intervals and the new 2016 drilling.
Island Mountain Exploration Update
With the Cow Mountain drilling now completed, three drill rigs have been mobilized to Island Mountain and are currently performing a first pass, 20,000 metre Phase I drilling program. The vein style of gold mineralization that dominates on Cow Mountain also occurs on Island Mountain but was never the primary focus of exploration or past development because of the incidence of higher grade massive sulphide replacement style mineralized bodies. As such, the 2016 Phase I program is designed to determine the extents of these vein systems, as well as test the down plunge extensions of the replacement bodies in areas that have never been drilled.
Qualified Persons Exploration activities at the Cariboo Gold Project are jointly administered on site by the Company's Project Managers, Maggie Layman, P.Geo. and Wanda Carter, 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 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 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 5ppb and upper limit of 10,000ppb. Samples with gold assays greater than 10,000ppb are re-analyzed using 50g fire assay with gravimetric finish, as well as 1,000g screen metallic fire assay. 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).
