Crawford and Sawyer Block: Aerotem Z1 Off-time


The Sawyer property is located on a tributary of St. Marys River, west of Cranbrook. The property consists of 1,566 ha (3,869 acres) overlying a Cretaceous age intrusive body (Sawyer Stock) localized along the contact between the uppermost Purcell Supergroup and the lowermost Windermere Supergroup. This stratigraphic contact is regionally important as it hosts a large number of documented MINFILE occurrences, dominated by Lead-Zinc mineralization. A lens of lead-zinc mineralization was previously reported on the property, as well as elsewhere in the immediately surrounding area. The presence of a Cretaceous intrusion is believed to play an important role in controlling local mineralization, as a probable source of mineralized fluids.

An Aeroquest International (“Aeroquest”) airborne geophysical survey was completed on the Sawyer property, comprised of electromagnetic, magnetic and radiometric data. The magnetic data documents one large, and several smaller, magnetic anomalies on either side of a small east flowing tributary into Sawyer Creek. Cretaceous intrusions correlated to the Bayonne Magmatic Suite are associated with both strong magnetic anomalies over the corresponding intrusions (i.e Fry Creek Batholith) and magnetic haloes surrounding the intrusion (i.e. White Creek Batholith). Therefore, these anomalies are tentatively interpreted to correlate to the intrusion with possible cupolas.

The Electromagnetic data document a number of small electromagnetic anomalies on both Z- and X-axis data, although the Z-axis data appears to document several larger anomalies on the south side of the tributary, south of the magnetic anomalies and the interpreted location of the intrusive phases. Of particular interest is the correlation of coincident Z- and X-axis electromagnetic anomalies with a UTEM anomaly identified by previous operators in 1997. A ground based UTEM survey identified “... two conductors or conductive zones striking across the small survey grid. The westerly (weak) conductor ... appears to be dipping shallowly to the east ... and has a depth extent of approximately 200 m.

The second conductor ... shallow to the east and appears to have a conductance more than 50 siemens
and a depth extent of at least 500 m”. Trenching and/or drilling was recommended to further evaluate these anomalies.

The radiometric data appears to document the intrusive lithologies, with correlation between potassium, thorium, uranium, and Total Count data. The data appears to indicate east-northeast trending anomalies, moderately to highly oblique to the mapped trend of the host strata. The radiometric anomalies appear to correlate moderately well with the magnetic data, interpreted to suggest that intrusive lithologies occupy topographic highs on the property, possibly associated with more resistant lithologies.

The results of the Aeroquest survey are very interesting, particularly with respect to previous UTEM survey results. Initial interpretation of the airborne geophysical data, together with limited data from previous programs, strongly suggest further evaluation of the property is warranted. In addition, previous, rather limited, exploration programs resulted in identification of lead-zinc mineralization, from which small hand samples returned grades up to 9.06% lead, 19.87% zinc and 10.05 oz/ton silver. Float “... samples from
scree indicate the mineralized horizon is broadly segregated into a lead rich band, combined lead and zinc, and a zinc rich band. The sulphides are contained within well defined bedding planes, with evidence of minor remobilization”.

Several vein-type mineralized occurrences have been identified and/or documented within, or in the immediate vicinity of, the Sawyer property. These may be polymetallic veins having low tonnage - high grade potential. Alternatively, they may be veins consistent with an Intrusion-Related Gold model and part of a high tonnage - low grade system with local high grade to bonanza grade gold veins. The preliminary deposit type under consideration in this program is that of a low tonnage, high grade vein type deposit.

In addition to the airborne survey, a limited soil program was completed on the property, comprised of a total of 249 soil samples over three lines, representing a continuation of 2005 program. The soil contours were located so as to extend on either side of a small, east-flowing tributary of Sawyer Creek, positioned below the cliffs in which high grade lead-zinc-silver float was previously reported and over the previously reported UTEM anomaly, which was subsequently confirmed in the airborne survey.

Analytical results returned moderate (to arguably high grade) results, with maximum values found as follows:

Molybdenum less than 13.1 ppm
Copper less than 81.4 ppm
Lead less than 242.8 ppm
Zinc less than 1,061 ppm
Silver less than 1.4 ppm
Gold less than 4.9 ppb
Tungsten less than 13.5 ppm
Bismuth less than 4.0 ppm
Manganese less than 8,228 ppm

Base metals plus silver anomalies are coincident and located below the cliff face and on the north side of the tributary, spatially associated with the UTEM / Aeroquest anomaly. Anomalous bismuth and tungsten values were returned from the northeastern ends of the two conoturs, coincident with the southern contact of the Sawyer Stock.

The coincident UTEM / Aeroquest / soil anomaly is considered a valid drill target and will be considered for drill testing as part of the 2007 drill program. Additional work is proposed to further develop the base metal plus silver mineralization previously reported (and possibly related to the geophysical / soil anomaly on the north side of the creek.
