VANCOUVER , July 2, 2019 /CNW/ - Kootenay Silver Inc. (KTN.V) (the "Company" or "Kootenay") is pleased to announce a drill rig has been mobilized to commence a minimum 3,000-meter core drill program at the Columba silver project ("Columba" or "Property") located in Chihuahua State, Mexico.
Columba covers a large high-grade epithermal vein system which the Company has mapped and sampled with grades retuning up to 693 gpt silver on surface. The project area includes a network of underground workings comprised of 4 shafts and 6 levels of drifts reported to measure over 1,000 meters in length. Historic* mine records indicate grades from these underground workings to range from 600 to 900 gpt silver with highlights of 1,900 gpt silver over 4 meters and 679 gpt silver along 133 meters of vein strike and 1.3 meters of vein width.

Mineralization at Columba is text book low to medium sulfidation epithermal vein hosted, displaying the classic zonation from non or weakly anomalous silver at high elevations that increase with depth into the classic high-grade zones that make them such profitable deposit types.

Sampling and QA/QC
Surface samples reported herein are a combination of grab, chip and panel chip. All technical information for the Columba exploration program is obtained and reported under a formal quality assurance and quality control ("QA/QC") program. Samples are taken under the direction of qualified geologists. Samples are then labeled placed in plastic bags, sealed and with interval, location and sample numbers recorded. Samples are delivered by the Company via courier to ALS Minerals ("ALS") in Hermosillo . The samples are dried, crushed and pulverized with the pulps being sent airfreight for analysis by ALS in Vancouver, B.C. Systematic assaying of standards, blanks and duplicates is performed for precision and accuracy. Analysis for silver, zinc, lead and copper and related trace elements was done by ICP four acid digestion, with gold analysis by 30-gram fire assay with an AA finish.
