KOOTENAY STEP-OUT DRILLING ENCOUNTERS 551 G/T SILVER & 20% COMBINED LEAD ZINC; 43-101 REPORT CONFIRMS HIGH PROBABILITY OF NEW MINERAL DISCOVERIES AT PROMONTORIO
Kootenay Gold Inc. has released step-out drill results and the updated 43-101 report for the Promontorio silver project in Sonora, Mexico. Highlights of step-out drill results include 551 grams per tonne (g/t) silver, 0.63 g/t gold and 20 per cent combined lead-zinc over three metres in KP 64 at the Ranch EM target. These results show similarities to the Main pit zone discovery area where brecciated mineralization grading 46.5 metres of 0.71 g/t gold, 71 g/t silver and 2.09 per cent lead-zinc was encountered in KP 58 in a step-out to the southwest. The Dorotea area is confirmed to be traceable to the northwest for up to 1,000 metres.
The 43-101 report states:
"Exploration work completed by Kootenay has demonstrated the Promontorio property is highly prospective for large low-to-intermediate sulphidation epithermal systems that may have developed in close proximity to a shallow-level porphyry system. There is a high probability that significant new mineral discoveries will be made on the property."
Update on step-out drilling
The current phase of drilling Kootenay has completed 4,273.5 metres in 13 diamond drill holes over four prospect areas. Promontorio Main pit zone, KP-58-09 to KP-59-09
Two holes were drilled as an approximate 50-metre southwest step-out of the Main pit zone:
KP 59 encountered mineralized breccia grading 46.5 metres of 0.71 g/t gold, 71 g/t silver and 2.09 per cent lead-zinc.
KP 58 drilled approximately 100 metres to the southeast encountered weakly anomalous values.
Ranch EM anomaly, KP-60-09 to KP-65-09
The first set of holes in the Ranch EM zone are positive showing a large target area as defined by the extensive alteration over 500 metres of cross-section with values of:
KP 64: Three metres of 0.63 g/t gold, 551 g/t silver and 20 per cent combined lead-zinc;
KP 60: 18 metres of 0.58 g/t gold, 13 g/t silver and 0.68 per cent lead-zinc including 2.0 metres 1.49 g/t gold, 26 g/t silver and 1.24 per cent lead-zinc.
Dorotea, KP-66-09 to KP-68-09
Holes KP 66 to 68 were drilled along strike of the Dorotea discovery. Holes KP 66 and 67 were drilled 80 metres northwest of KP 55 to 57 and KP 68 was drilled 80 metres to the southeast along strike. All holes intersected the sulphide zone returning:
KP 68: Six metres of 1.56 g/t gold, 26 g/t silver and 1.71 per cent lead-zinc;
KP 67: 10.5 metres of 0.97 g/t gold, 31 g/t silver and 0.65 per cent lead-zinc; including three metres of 1.83 g/t gold, 58 g/t silver and 0.98 per cent lead-zinc;
KP 66: Three metres of 0.57 g/t gold, 29 g/t silver and 2.45 per cent lead-zinc.
Fault offsets are apparent and more than one zone may be present. Mineralization is open ended and additional drilling is required. Hole KP 69 was drilled into a copper showing which is 160 metres southwest of KP 55 to KP 57 and assays are pending.
Dorotea northwest, KP-70-09 to KP-71-09
KP 70 to 71 are approximately 1,000 and 600 metres, respectively, to the northwest of the Dorotea discovery, results are pending. Drill results continue to confirm the large size potential of Promontorio with significant mineralization being encountered in all target areas tested in the current program to date.

Updated 43-101 report
Highlights from the updated 43-101 report include recommendations that: "Future exploration efforts should focus on defining a 43-101 resource estimate for the Main pit zone, infill drilling on the Dorotea prospect, continued exploration drilling along mineralized northeast- and northwest-trending structures and follow-up ground exploration surveys to the north of the Yaqui River over areas where base and precious metal showings have been found. The following work is recommended for the Promontorio property with the main focus directed at assessing the economic potential of the Main pit zone, infill drilling on the Dorotea prospect and additional exploration surveys over the areas where new mineralization and or alteration zones have been outlined."
Recommended work program
Phase I
Exploration work directed at evaluating the surface extensions of the mineralized zones along northeast- and northwest-trending structures that bisect the Main pit zone and the Dorotea prospect. In addition, selected airborne EM anomalies would be tested. Ground surveys would include: geochemical sampling, three-dimensional induce polarization and trenching. A total of 5,000 metres of drilling would be required to test mineralized targets.
Phase II
Would consist of delineation drilling and metallurgical testing of the Main pit zone in order to better define mineralization and produce a National Instrument-43-101-compliant resource estimate. Drilling would consist of approximately 30 reverse-circulation (RC) and five HQ core holes, totalling 15,000 metres and be focused on the area bounded between 628250E and 628650E and 3110800N and 3111000N. Reverse-circulation drill holes would target gaps within the present Main pit zone drilling and be angled between 70 to 90 degrees. Additional reverse-circulation drilling would test the Main pit zone to the northeast of holes KP-11-07 and PK-53-08 and to the southwest of KP-13-07 and KP-46-08. Mineralized zones would be sampled at one-metre to 1.5-metre intervals.
Phase III
Work would focus on geological mapping, soil geochemical, geophysical and trenching surveys to the north of the Yaqui River, where new mineralization and or alteration zones have been located. A total of 3,000 metres of drill core will be required to test targets generated from this work. In addition, a regional gravity survey is recommended to cover all areas and trends associated with mineralizing events. The purpose of the survey would be to define gravity targets suggestive of large hidden sulphide bodies and or hidden high-level porphyries.
The updated 43-101 technical report will be filed shortly and available on SEDAR.
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 co-ordinates can be viewed at the Kootenay website.
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 labelled, 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 International Plasma Labs Ltd. (iPL) 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 iPL Laboratories in Richmond, 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. iPL Laboratories also has its own system of replicate analysis and blanks which it provides to the company. Each pulp is analyzed using iPL's AU(FA/AAS) Ag/ore-grade by multiacid digestion ICP (Cu/Pb/Zn/Ag) assay package. This is a multiacid digestion with gold analyzed with an AA finish with overlimits done with gravimetric finish and silver analyzed by ICP (inductively coupled plasma) and a gravimetric finish on overlimits while zinc was analyzed by ICP and lead by fire assay. Sample lengths vary from 0.5 metre to two metres in width with the majority being 1.5 or 2.0 metres.
The foregoing geological disclosure has been reviewed and verified by Kootenay's chief executive officer, James McDonald, PGeo (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. The 43-101 technical report was authored by Guy Mac Gillivray, PGeo (a qualified person for the purpose of National Instrument 43-101, standards of disclosure for mineral projects) who was contracted independently to write the report.
