LA NEGRA SILVER DISCOVERY UPDATEKootenay Silver Inc. is releasing results on the final two drill holes from its inaugural phase I drill program on its new La Negra breccia silver discovery, situated approximately 6.5 kilometres north of Kootenay's flagship Promontorio silver resource in Sonora, Mexico. A total of 25 holes for 3173 metres of drilling have been completed along an approximate 400 metre strike length of the breccia. Silver mineralization is exposed at surface and is shown to extend to a vertical depth of at least 190 metres (approximately 110 metres above sea level) and along the entire length of the breccia, where drill testing and surface sampling was conducted. The breccia silver mineralization is open to the east and at depth, with possible extensions to the west as indicated from surface exposures.
States Kootenay President and CEO James McDonald "We are very pleased to conclude our inaugural drill program on the La Negra Diatreme Breccia system that has resulted in a significant and exciting new silver discovery in Mexico. Drilling continues to return high grades and shows a remarkable consistency of silver mineralization on surface and at depth across the entire length of the breccia. Results from the inaugural program will be immediately compiled and collated in a 3D model showing the geologic controls and assay results. This compilation will be used to design the next drill phase which is expected to begin early in the New Year. Based on the outstanding results to date, the objective is to move the project quickly to a maiden NI 43-101 resource calculation."
The remaining two holes LN 24 and 25-14 are reported herein, along with complete results of the 25 hole drill program. Drill hole LN 24-14 encountered high grades of silver starting at surface on the same section as LN 22 and 23-14. This is also the eastern most section drilled. LN 25-14 hit 60 metres of silver mineralized breccia from surface, which is interpreted to confirm a south dip in this area of the breccia.
Details of the final two drill hole intercepts are in the following table:

Management believes that La Negra is a diatreme breccia which implies good depth potential as diatreme breccias can extend to depths of 100's of metres. The depth potential in the La Negra Breccia is underscored by hole LN 21-14 as it bottoms in high silver grades at a vertical depth of around 150 metres showing the potential for resources to depth. The depth of the high silver grade shows the grades are primary so not a result of supergene enrichment. Due to faulting and possibly the nature of the breccia contact itself the width of the breccia body is not well defined at this time. Thus far the apparent widths of the breccia interpreted from drilling are varying from about 60 to over 100 metres within a broader 200 by 500 metre area of breccia outcrop exposures. The La Negra Breccia is cut by two northwest trending faults across which the dip of the breccia changes from near vertical to moderate southerly dips. This is evidenced by holes LN 11, 12, 14, 18, 19 and 20, which were drilled through the breccia into the footwall or directly within the footwall thus missing the bulk of the breccia body. Hole LN 25-14 drilled to the north confirms a southerly dip encountering 60 metres of breccia from surface followed by about 50 metres of stockwork and argillic alteration.
Current Phase I Drill Program
Drilling in the Phase I program was conducted in widely spaced fences along 400 of 500 metres of La Negra's length to provide information on the sub-surface grade, continuity and geometry of the mineralized Breccia system. Current holes were broadly spaced as single holes or fences of holes from the same platforms in 115 to 50 metre spacing's along strike. Extensive zones of breccia and stockwork were encountered along the strike length and dips seem to vary from steep northerly dips to moderate southerly dips. The Phase I drill program totaled 25 HQ diametre core holes with 3173.5 metres of drilling.
La Negra Silver DiscoveryThe La Negra Breccia prospect is situated approx. 6.5 kms north of Kootenay's flagship Promontorio Silver Resource in Sonora, Mexico and is contained within a 25 x 15 km mineralized corridor, the 'Promontorio Mineral Belt.' The current Phase I drill program on La Negra follows a highly successful trenching and surface sampling program that confirmed widespread silver mineralization exists over a large 100 to 200 metres by 500 metres area on surface.

QA/QCCore is being detailed logged and sampled with half the core being bagged, tagged, catalogued, sealed and sent to an accredited assay lab for analysis. A quality control program including blanks, standards and replicates is being used similar to that used on the Promontorio drill program. Geotechnical data such as recovery, RQD and density are being recorded also. All drilling has been with HQ core and is being done by BD Drilling from Guadalajara, Mexico. Further Quality Assurance and Control procedures and details on assays procedures and laboratories used are disclosed on the Kootenay Silver Inc. website.The foregoing geological disclosure has been reviewed and verified by Kootenay's CEO, James McDonald, P.Geo (a qualified person for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects).
