Kootenay Silver Inc Commences Drill Program Underway on Promontorio's La Negra Mineralized Diatreme Pipe
Aug 28 14
Kootenay Silver Inc. announced drilling has commenced on its La Negra Diatreme Breccia prospect, located within Kootenay's Promontorio property and approximately 6-7 kms north of Kootenay's Promontorio Silver Resource in Sonora, Mexico. The program is contracted to be a minimum of 2,500 meters of core drilling with HQ diameter core. It is anticipated 15 to 20 holes will be drilled in the inaugural program. Drilling is being conducted by BD Drilling of Guadalajara, Mexico. Drilling will test in widely spaced fences the diatreme pipe along 400 to 500 meters of its length providing information on the sub-surface grade, continuity and geometry of the mineralized pipe. Surface sampling from bedrock exposure shows silver mineralization is remarkably consistent throughout the breccia's exposed breadth and length (between 100 to 200 meters by 500 meters). The average of all samples is 65 gpt silver from 50 three meter chip samples in trenches, 19 two meter square chip panels and 31 grab samples. Airborne geophysics was effective in mapping the southern contact of the breccia and indicates the breccia could be twice the aerial extent of the visible bedrock exposure. The current mineral estimate on Promontorio effective date March 31, 2013 contains a combined Measured and Indicated silver resource of 92,428,000 silver equivalent ounces (39.9M oz's Ag, 508K oz's Au, 394.8M lb's Pb, 462.2M lb's Zn). In addition to the measured and indicated silver resources, there are an additional 26,814,000 silver equivalent ounces in the Inferred category (12.8M oz's Ag, 147 oz's Au, 99.5M lb's Pb, 109.1M lb's Zn). Measured and Indicated resources are contained in open pit resources of 44,504,000 tonnes grading an average of 64.32 gpt silver equivalent (27.77 gpt Ag, 0.35 gpt Au and 0.87% Pb+Zn) and resources outside of the open pit of 215,000 tonnes grading an average of 56.96 gpt silver equivalent (22.89 gpt Ag, 0.28 gpt Au and 0.95% Pb+Zn). Inferred resources are within open pit resources of 14,564,000 tonnes grading an average of 51.95 gpt silver equivalent (24.95 gpt Ag, 0.28 gpt Au and 0.59% Pb+Zn) and resources outside of the open pit of 1,265,000 tonnes grading an average of 61.17 gpt silver equivalent (26.57 gpt Ag, 0.37 gpt Au and 0.74% Pb+Zn). The current NI 43-101 Resource Estimation conducted on Promontorio by SRK Consulting Inc. (U.S.) of Lakewood, Colorado, included gold assay results in the updated resource estimation. As a result of the addition of gold, the mineral resource is now contained in a single larger optimized Whittle Pit, as opposed to two individual smaller pits as reported in the August 21, 2012 resource estimate. The decision to include gold in the resource estimation follows extensive metallurgical testing and technical analysis conducted by ALS Minerals of Kamloops, British Columbia that confirmed up to 94.5% recovery of gold from pyrite concentrates from the Promontorio resource can be achieved using a post pressure oxidation treatment process.
Kootenay Silver Inc. Announces Drill Program to Commence August 2014 on Promontorio's La Negra Diatreme Breccia Prospect
Jul 22 14
Kootenay Silver Inc. announced drill contracts are in place, drill targets have been identified and road construction is underway in preparation for an upcoming phase I drill program on it's La Negra Diatreme Breccia prospect, located approx. 7 kms north of Kootenay's Promontorio Silver Resource in Sonora, Mexico. Drilling is slated to commence in late August 2014 and is expected to include a minimum 2,500 meters of core drilling. The program follows a recently conducted strategic hand trenching and chip sampling program that indicated widespread silver mineralization is present on surface within the entire 100 by 400 meter core of the La Negra Diatreme Breccia. The current drilling campaign is designed to determine the extent and grades of silver mineralization extending from surface to depth.
Kootenay Silver Inc. Announces Further Results from Six Trenches from its Strategic Hand Trenching and Chip Sampling Program on its La Negra, Diatreme Breccia Prospect

Kootenay Silver Inc. announced further results from six trenches from its strategic hand trenching and chip sampling program on its La Negra, diatreme Breccia prospect, located approx. 7 kilometers north of its Promontorio Silver Resource in Sonora, Mexico. A total of 50 samples were taken in 3 meter intervals for 150 meters of trenches across the 6 trenches ranging from 21 to 30 meters in length. All trenches returned silver mineralization throughout their length. Results further augment previous assays from the program, indicating robust and consistent grades of widespread silver mineralization being present within the entire 100 by 400 meter core of the La Negra Diatreme Breccia. Highlights from Hand Trenching and Chip Sampling Program include: 98.9 gpt Ag over 21 meters in Trench 1; 59.1 gpt Ag over 21 meters in Trench 5; 42.1 gpt Ag over 27 meters in Trench 2; 39.2 gpt Ag over 30 meters in Trench 3; 33.5 gpt Ag over 30 meters in Trench 6; and 16.1 gpt Ag over 21 meters in Trench 4. The hand trenching and chip sampling program was designed to gain a better understanding of the grade potential and continuity of silver mineralization within the breccia in preparation for a proposed upcoming drilling program. Current results further support and augment previous assays from sampling conducted along the entire length of breccia. They each support earlier results that returned anomalous silver across the total area of the exposed breccia. Included were 19 chip samples taken from 2 by 2 meter panels returning an average of 107 gpt Ag within a larger sample set of 50 samples (19 chips in 2 by 2 meter panels plus 31 grab samples) that averaged 77 gpt silver. In conjunction with the sampling program, the breccia was mapped over an area approximately 100 to 200 by 500 meters and revealed extensive bedrock exposure in an area measuring 100 by 400 meters where the trench sampling was conducted. The breccia is believed to be a diatreme pipe that forms a prominent hill with approximately 120 to 130 meters of relief. Airborne geophysics was effective in mapping the southern contact of the breccia and indicates the breccia could be twice the aerial extent of the visible bedrock exposure.
