Kootenay Silver (TSXV:KTN) enjoyed a share price boost of nearly 10 percent on Wednesday after announcing results from the last three holes of the Phase II drill program completed at its La Negra diatreme silver discovery. La Negra is located at Kootenay's Mexico-based Promontorio project, and while the company has been conducting work there for some time, it wasn't until last October that it confirmed it as "a substantial new silver discovery." The launch of Phase I drilling followed shortly thereafter, and when that was completed in December, Kootenay revealed plans to "move the project quickly to a maiden NI 43-101 resource calculation." Phase II drill program Phase II drilling began in January in support of that plan. As James McDonald, the company's president and CEO, explained at the time, the program's overall objective was to "determin[e] the overall size and extent of La Negra's contained silver" by "systematically building on the multiple high-grade silver results and widespread silver mineralization returned from previous surface sampling and Phase I drilling." Based on McDonald's comments in Wednesday's release, the Phase II program was successful. "[T]he program has been a major step forward for the La Negra Silver discovery," he said, adding, "[t]he continuity of silver grades and consistency of silver mineralization to depth set the stage for the advancement of La Negra. Moreover, results reinforce La Negra's potential for a low-cost, open pittable silver resource." Sixteen holes covering 3,040 meters were completed as part of the program, with results being released in three stages. The first batch of six holes intercepted "significant widths and grades of silver mineralization," while the company said the second batch of seven holes extended the silver mineralization at La Negra by a further 150 meters in depth. As mentioned, the third and final batch was comprised of three holes — according to Kootenay, high-grade intercepts were encountered in two of the three holes, with the extent of the mineralized breccia being expanded to the northeast and to depth.
