Kootenay Silver Inc. is pleased to announce drill crews are on site at the Columba high-grade silver project (the “Property”), located in Chihuahua State, Mexico in preparation to begin the 2022 drill program. Two diamond core drills are scheduled to arrive within the next few days.
Drilling for this 15,000-meter program will focus on several areas on the property, including:
Initial focus of this program will be on deeper drill testing on the F Vein and expanding on the D and B Vein intercepts. This plan follows up promising results from previous drill programs highlighted by these examples of many:
F Vein
CDH-19-41: 787 gpt silver over 5.95 meters within 650 gpt silver over 7.45 meters and 159 gpt silver
D Vein
CDH-21-110: 932 gpt silver over 6.07 meters within 650 gpt silver over 17.8 meters and 453 gpt silver over 29.9 meters
B Vein
CDH-21-82: 1186 gpt silver over 4.6 meters within 9 meters of 691 gpt silver
JZ Trap Zone:
CDH-21-103; 2035 gpt silver over 6 meters within 805 gpt silver over 17 meters and 333 gpt silver over 44 meters
East Block:
CDH-21-101: 1190 gpt silver over 0.5 meters within 459 gpt silver over 1.6 meters

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 from core cut in half with a diamond saw under the direction of qualified geologists and engineers. Samples are then labeled, placed in plastic bags, sealed and with interval and sample numbers recorded. Samples are delivered by the Company to ALS Minerals (“ALS”) in Chihuahua. The Company inserts blanks, standards and duplicates at regular intervals as follows. On average a blank is inserted every 100 samples beginning at the start of sampling and again when leaving the mineral zone. Standards are inserted when entering the potential mineralized zone and in the middle of them, on average one in every 25 samples is a standard. Duplicates are taken in the mineralized zone, on average 1 to 2 duplicates for each hole.
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. All drilling reported is HQ core and has been contracted to Globexplore Drilling from Hermosillo, Sonora, Mexico.
