KOOTENAY DRILLING CONFIRMS WIDESPREAD, HIGH-GRADE MINERALIZATION: HIGHLIGHTS INCLUDE 18.4 METERS GRADING 950 G/T @ 151 METERS GRADING 162 G/T SILVER-EQUIVALENT AT PROMONTORIO
Kootenay Gold Inc. has released results from the first phase of drilling on the Promontorio silver project in Sonora, Mexico. The 22-hole program included drilling on the Pit, Central and Adobe breccias.
Drilling has encountered wide to moderate intervals of high-grade silver-gold polymetalic breccias in a porphyry breccia setting. Results received to date report 20 of the 22 holes intersected significant precious and base metal mineralization starting from surface and extending to depth.
Jim McDonald, chief executive officer of Kootenay, commented: "These results indicate that the individual breccias drilled in the first phase are part of a single, large mineralized system with distinct characteristics indicative of a porphyry system. Accordingly, drill data suggests the Promontorio may contain a deposit of larger scale and scope than previously conceived."

Pit breccia
Holes KP-01-07 to KP-13-07 drill tested the Pit breccia where previous surface chip sampling returned 480.14 grams per tonne Ag, 2.51 gpt Au, over 19 metres and 75.6 gpt Ag and 0.99 gpt Au over 25 metres including 150.67 gpt Ag and 0.86 gpt Au over six meters. Drilling tested the Pit breccia along a strike of 120 metres and a dip extent of 160 metres. Andesite is the host rock and is brecciated, fractured and variously altered and mineralized throughout. The best grading mineralization is generally within a five-metre-wide to 25-metre-wide zone that occurs near the bottom of the breccia above a reverse fault. Brecciation is variable throughout the holes but fracturing and alteration (weak to strong) occur throughout the intercepts.
Adobe breccia
Holes KP-17-07 to KP-07-20 and KP-22-07 drill tested what is called the Adobe breccia. These holes are significant as they encountered a well-developed and well-mineralized breccia starting from surface and continuing to a minimum vertical depth of 195 metres. Also, alteration changes from a calcite-dominant propylitic alteration in the Pit breccia to a biotite-sericite-silica alteration in the Adobe breccia.
Central breccia
Holes KP-14-07 to KP-16-07 were drilled into the central breccia to test a historic exploration shaft and surface chip sampling that returned 62.78 gpt and 0.402 gpt Au over 11 metres including 152.5 gpt Ag and 1.41 gpt Au over 3.5 metres.
Drilling reported herein tested an area measuring approximately 175 metres by 270 metres, excepting a single hole drilled approximately 200 metres to the east (hole KP-21-07). Further airborne geophysics indicate the mineralized area may extend over an area measuring over 2,000 metres by 500 metres.

Assays for hole KP-03-07 and KP-21-07 are pending as are additional intervals of each hole not reported above. A complete table showing the detail of collar co-ordinates and of each sample interval used to calculate the above tables will be posted on the company's website. All intervals reported are drill core length with true widths in the Pit breccia interpreted to be 80 to 90 per cent of drilled width. True widths in the Central and Adobe breccias are not known at this time.
Mineralization
Mineralization occurs as pyrite, galena, sphalerite and possible silver sulphosalts within fractures, breccias and as disseminations within an andesitic flow unit. In the Pit and Central breccias alteration is dominated by sulphides associated with calcite veining and a propylitic carbonate chlorite alteration. The best grades occur within a 25-metre interval immediately above a northeast-trending reverse fault interpreted to be coeval with mineralization. Westward toward the Adobe breccia alteration grades into a distinct potassic biotite alteration over printed by strong phyllic alteration with an increase in silica and a decrease in calcite. Sulphide mineralization in the Adobe breccia area is generally stronger and more ubiquitous as is brecciation. Only one hole in the Adobe breccia tested the reverse fault, that is KP-22-07 which intercepted the fault at 200 metres and like Pit breccia mineralization encountered the best grades in a 25-metre interval above the fault.
Drilling
Drilling was contracted to Layne Drillling out of Hermosillo, Sonora, Mexico, and consisted of about 3,000 metres of HQ-sized core in 22 holes.
Sampling and assaying
All core samples were taken by cutting the core in halves with a rock saw with one-half going back to the core box for reference and the other being placed into a plastic sample bag. Each sample bag is labelled with a number and corresponding numbered tag in the bag and the top is sealed with wire. Each plastic bag is placed in a sack and each sack is sealed with a zip tie. The samples in each bag are then recorded and delivered to iPL's sample prep lab in Hermosillo, Sonora, Mexico, where a pulp is prepared and sent to iPL Laboratories in Vancouver, B.C., for analysis.
All samples were taken in 0.3-metre to 2.0-metre intervals and the majority was 0.4 to 1.0 metre wide. Assays were done by multiacid digestion. Gold was analyzed with an AA finish with overlimits done with gravimetric finish while silver was done with ICP and a gravimetric finish on overlimits while zinc was analyzed by ICP and lead by assay. Blanks are inserted both by the company and iPL, and duplicates are run by iPL as quality control and assurance checks.
All fieldwork related to the drilling was conducted and supervised by Resource Geosciences De Mexico, S.A. de C.V., a geologic consulting firm based out of Hermosillo, Sonora, Mexico.
The foregoing geological disclosure has been reviewed and verified by Dr. Trygve Hoy, PGeo (a qualified person for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects), based upon solely on the assay certificate and other information made available to Dr. Hoy. Dr. Hoy has not visited the property or verified the sampling, analytical and test process protocol. Dr. Hoy is a consultant for the company engaged to provide technical geological consulting services from time to time. The disclosure is for the geological disclosure in this news release only.
Based on these initial results the company has commenced an IP survey, which should be completed late 2007 and will assist in phase II drill planning set to commence early 2008. |
