Kootenay Silver Inc announced assay results from the last seven core drill holes competed from its 2019 drill program at its Columba high-grade silver project, located in Chihuahua State, Mexico. Kootenay President and CEO James McDonald states, "We continue to be pleased with drill results from Columba that now indicate significant strike extensions to the F vein and a potential new zone in the B vein south of the old mine workings. Hole CDH-19-35 extends F vein mineralization approximately 225 meters from high grade intercepts in holes CDH-19-11 and 12. High silver grades have now been encountered in the F vein for over 700 meters of strike length and remains open to depth and strike. Additionally, hole CDH-19-38 is also very positive as it intercepted 628 gpt silver over 1.5 meters in the B vein; 650 meters from old mine workings."

Highlights of holes CDH-19-35 to CDH-19-041:

Hole CDH-19-035:
405 gpt silver over 2.28 meters within a wider interval of 103 gpt silver over 11.35 meters in a footwall vein to the F Vein;
494 gpt silver over 1.35 meters in the F Vein within 274 gpt silver over 3.0 meters and 60 gpt silver over 23.0 meters;
547 gpt silver over 1.0 metre within a wider interval of 114 gpt silver over 7.05 meters in a hydrothermal breccia in the E Vein.

Hole CDH-19-038:

628 gpt silver over 1.5 meters within a wider interval of 301 gpt silver over 4.63 meters and 175 gpt silver over 10.0 meters in the B Vein. Quartz, quartz-barite veins and veinlet stock work and silicified rhyolite.

The following are highlights of twinned holes to test triple tube drilling for achieving better recoveries. Results showed a 1 to 9% increase in recovery across mineralized intervals. Within intervals grade and widths with triple tube show both increases and decreases relative to better recoveries. More holes are needed to determine the effect of recovery on grade and widths.

Hole CDH-19-040: Twin of CDH-19-005:
808 gpt silver over 0.88 metres over a wider intercept of 194 gpt silver over 4.9 metres intercepting banded quartz vein (F Vein).

Hole CDH-19-041: Twin of CDH-19-008:
650 gpt silver over 7.45 meters within a wider interval of 159 gpt silver over 39.9 meters intercepting banded quartz vein (F Vein);
Including: 919 gpt silver over 1.15 meters; 953 gpt silver over 1 meter; 527 gpt silver over 1 meter; 860 gpt silver over 1 meter and 715 gpt silver over 1.8 meters.

A follow up drill program is being designed based on the results of the 2019 drill program. Numerous priority areas have been identified and additional structures remain untested all of which will be addressed in the upcoming 2020 drill program. This program is expected to start in the next few weeks toward the beginning of February and once the program has been reviewed and approved details of number of holes and meters will be provided.
