Kootenay Stepout Drilling Begins at Promontorio
Kootenay Gold Inc. announce drilling is underway at Promontorio. The program is designed to drill untested targets; expand on mineralization discovered at the Pit Discovery; and step-out across the 2km Dorotea Trend. The 5000 meter program expected to be completed by year end, will focus on targets identified by systematic exploration (3D IP Geophysical Survey; Mapping; Sampling; EM Airborne Study; Trenching; Drilling) across this large silver-lead-zinc-gold mineral system; then follow up in detail the strongest mineralized zones.
3D Induced Polarization Geophysical Survey
Results of data from the Dorotea 3D Induced Polarization geophysical survey, merged with data from the original I.P. survey over the Promontorio mine and the model shows the large, L-shaped anomaly covering the pit mineralization (see news release dated July 23, 2009) continues to the northwest and north covering the Dorotea discovery area.
The new survey has identified two discrete chargeability anomalies along the Dorotea trend using the +12mV/V contour. The larger anomaly is centred 2.5km from the Promontorio pit area and measures roughly 550m x 400m. The smaller anomaly is roughly 160m x 130m and correlates well with limited drilling at the Dorotea showing completed in late 2008 that encountered 34.5 meters grading 1.73 grams per tonne (“gpt”) gold, 74.83 gpt silver and 2.4% lead + zinc reported in hole KP 56 and 6.0 meters grading 5.92 gpt gold, 167.20 gpt silver and 1.625% lead + zinc reported in hole KP 55 (see news release dated February 5, 2009 for full results).

Metallurgical
In additional news G&T Metallurgical Services Ltd. of Kamloops, B.C. was engaged to conduct a preliminary metallurgical assessment of a 115 kilogram composite of HQ sized core from 138 meters to 197 meters in hole KP 22 in the Pit Discovery, with the goal of developing a suitable process to recover lead, zinc, silver and gold contained in the sample.
The master composite contained approximately 0.9 percent lead, 1.0 percent zinc, 56 g/tonne silver and 0.6 g/tonne gold. The sample responded well to a standard lead/zinc sequential flotation flow sheet producing concentrates that would be highly saleable in the event a deposit is developed.
Locked cycle tests were conducted, in which 85 percent of the feed lead was recovered into a final lead concentrate containing 62 percent lead and 4250 g/tonne silver. On average, 82 percent of the silver reported to the lead concentrate and 7 percent reported to the zinc concentrate. Zinc was 91 percent recovered to the final zinc concentrate which graded 57 percent zinc.
Batch cleaner test results indicated that 87 percent of the gold could be recovered into a pyrite concentrate, following lead and zinc recovery, which contained 14 percent of the feed mass. Sodium cyanide leach tests conducted on pyrite concentrates showed further work is required to develop a suitable process to extract gold from the pyrite concentrate. Approximately 87% of the gold reported to the pyrite concentrate with approximately 6 percent of the gold in the lead concentrate.
Further test work is recommended to optimize the process grinding requirements, and review the variability of the metallurgical performance and gold association over different areas of the deposit.
Drilling
Drilling is all core and has been contracted to BDW International out of Guadalajara Mexico and all core has been HQ sized. Drill hole coordinates can be viewed at www.kootenaygold.ca.
Sampling and Assaying
All core samples are cut by a rock saw with one half being returned to the core box for reference and the other being bagged in a plastic sample bag which is labeled, tagged, documented and sealed with wire. Each sample is placed in a rice sack and sealed with a zip tie. All samples are recorded and delivered to ALS Chemex laboratories for sample preparation lab in Hermosillo, Sonora, Mexico. Receipt of the samples is signed off at the preparation lab. Pulps of each sample are then prepared and sent to ALS Chemex in North Vancouver B.C. Canada an ISO 9001-2000 certified full service laboratory. All of the samples referred to herein are core samples. A QA/QC program which includes the regular insertion by the Company of duplicates, blanks and standards has been instituted. ALS Chemex also has its own system of replicate analysis and blanks which it provides to the Company. Each pulp is analyzed using AU(FA/AAS) Ag/Ore-Grade by Multi acid digestion ICP (Cu/Pb/Zn/Ag) assay package. This is a multi acid digestion with gold analyzed with an AA finish with over limits done with gravimetric finish and silver analyzed by ICP (inductively coupled plasma) and a gravimetric finish on over limits while zinc was analyzed by ICP and lead by fire assay. Sample lengths vary from 0.5 to 2.0 meters in width with the majority being 1.5 or 2.0 meters. Certain technical engineering data is also being collected from the core including RQD (Rock Quality Designation), recovery, photographs and specific gravity measurements.
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). Mr. McDonald is a director of the Company.
