Kootenay Silver Reveals Columba Exploration Drill Program ResultsBy Miriam Bello | Thu, 07/07/2022 - 17:25
Kootenay Silver is a silver exploration company actively engaged in the development of major silver projects in Mexico, which include Columba and El Copalito in Chihuahua. Now that more is known about Columba’s potential, the company set about to highlight its potential.
Columba is a project in northern Chihuahua. It is a classical high-grade low sulfidation epithermal vein system, common for Mexican geology. Kootenay’s 2019 drill campaign was the first to take place in 30 years. Historic data from underground workings at a depth of 100 meters include nine individual channel samples, taken along a 25m length of vein, where several high-grade intervals were reported to return silver values from 350g/t over 1.2m to a high of 1,900g/t over 4m.
Columba hosts a series of high-grade silver veins on the surface as well as extensive underground workings, explained James McDonald, President, CEO and Director, Kootenay Silver. On the surface, four shafts are reported to extend to depths of up to 200 meters and connect to at least six levels of widespread underground drifts, covering lengths of up to 1km. The majority of this work appears to have been done around 1910, with an estimated 70,000 to 100,000 tons being mined.
By 2020, the company had drilled 6,800m with very consistent results. On the original vein, it had wide-spaced holes along 700m, with big gaps in between. The follow-up phase two drill program comprised of 43 holes, totaling over 9,114 meters. It targeted infill and step-out drilling within the high-grade F vein and the J-Z Vein area .“It is a very strongly mineralized vein,” said McDonald.
McDonald shared the most relevant highlights from the company’s drilling program in 2021, which includes Hole CDH-21-110. Here, Kootenay found 650g/t silver over 17m within a wider interval of 269g/t silver over 29.9m in the D Vein. Hole CDH-21-103 showed 2,035g/t silver over 6m, within a wider interval of 333g/t silver over 44m, also in the D Vein. Finally, Hole CDH-21-094 intersected 809g/t silver over 2.63m within a wider interval of 354g/t silver over 9m in the F Vein.
Geologically, Columba presented few challenges, according to previous comments from McDonald. “There is enough exposure to be able to map the veins and targets fairly easily. However, the agreement to acquire the rights to the concession took a year. Our team in Mexico negotiated the mineral rights and access to the surface, advancing the negotiations in a very fast and professional way,” he said.
Financially, McDonald explained the company has had 359 million shares issued and an average daily volume of 763,195 shares. “There is an excellent leverage to silver and as Columba is a high drill discovery we can guarantee a probability of investment,” he said.
