The Copalito Project is a classic low sulphidation epithermal vein system which has numerous small old workings and no evidence or reports of historic exploration drilling. The Property consists of seven concessions totaling approximately 3,700 hectares and is located 35 kilometres east of McEwen Mining’s “El Gallo Mine” complex in Sinaloa State, along the western fringes of the Sierra Madre Occidental in northwestern Mexico. Copalito has good access, topography and infrastructure. Kootenay can acquire a 100% ownership in the concessions by making staged payments over a 4-year period totaling US$985,000. The Company at its option may accelerate the payments due under the Agreement. Upon earn-in the vendors will retain a 0.5% net smelter return.
EXPLORATION WORK COMPLETED AT COPALITO
Extensive mapping and sampling work has been carried out by the Company in 2018 and 2019. The vein system comprised of numerous veins with many of the individual veins traced over strike lengths of up to two (2) kilometers. Veins vary in width from 0.5 to 15 meters at surface. Sampling in preparation for the initial drill program returned up to 7.2 gpt gold and 3,770 gpt silver in grab samples and up to 8.2 gpt gold including 583 gpt silver over a 1.1-meter chip sample.
2020 DRILL PROGRAM
The objective of the first phase drill program totaling 4,153 meters over 40 drill holes was to test each of the known vein structures to determine grade, continuity potential and build a prioritized inventory of veins. The Program successfully verified the existence and continuity of mineralized gold and silver veins at the project, where there is no evidence of modern exploration. Results demonstrate several areas having potential to host high grade deposits that will be the focus of follow up drilling.
Results of forty short holes, averaging approximately 100 meters a hole, targeting a range from 50 to 184 meters in depth, confirm that gold and silver mineralization continue at depth. This mineralization is associated with a significant percent of other elements including lead, zinc and copper, which provide an important addition to the precious metals. The best intersections are related to dilation zones, “mineralized shoots”, within the veins of the low sulphidation system.
The first four (4) holes tested the 5 Senores Vein located in the southern portion of the Property. These holes show good continuity for at least 500 meters of strike length along the 5 Senores Vein. In addition, drilling results from the veins tested to date on the project have returned high-grade mineralization matching up with the promising results garnered form surface sampling.

Kootenay completed the first ever drill program totaling 4,153 meters over 40 drill holes on the Property in 2020. This program was designed to test several vein targets located on the Property. Future drilling will test the extension and continuity of the high-grade areas in a follow-up program to be determined in 2021.
Mineralization is hosted within classic low sulfidation epithermal quartz and rare calcite veins. Multiple mineral events are evidenced by banded mineralized textures, multiple cross cutting veins/veinlets, laminated banding of chalcedonic and crystalline quartz, sulfide replacement and infillings of breccia matrix. Sulfide content is generally low but does range to 20% or more in hand samples. Sulfides and their oxide equivalents include fine grained pyrite, black and yellow sphalerite, galena, chalcopyrite and silver sulphosalts. Some zonation is becoming apparent with veins in the northeast being higher in gold and base metals and those in the south being high in silver and low in base metals.
