The company is now known as FUSE Cobalt.
This report, updating Wildcat's work at the Foster River Property comes from the MD&A for the nine months ending September 30, 2008 (on SEDAR). (Zn = zinc, Pb = lead, Cu = copper, Au = gold):
Wildcat holds a 100% interest in the Foster River zinc-lead property in Northern Saskatchewan, located approximately 120 km north of the town of La Ronge. The property consists of five claims (15,657 ha), two of which (3784 ha) are subject to a 2% net smelter royalty.
Multiple lines of evidence including age, metamorphic grade, lithologies of accompanying rocks and the presence of minerals characteristic of the SEDEX (sedimentary exhalative) type of Zn-Pb deposits, highlight compelling parallels between the Foster River Zn-Pb mineralization and that of the Broken Hill type Zn-Pb orebodies in Western Australia and elsewhere in the world. Broken Hill itself is a large deposit containing approximately 300 million tonnes of ore grading in excess of 15% combined Zn and Pb.
Past exploration of the Foster River property, undertaken over decades by prospectors and major companies, outlined several Zn-Pb occurrences of which the most significant is the Sito
Wildcat deployed field crews to the Foster River property in June 2008. Exploration and mapping activities, briefly interrupted due to forest fires, continued until August 16th. Principal investigations focused on structural investigation and mapping and, under the direction of Prof. P. Spry of Iowa State University, comparative studies of the composition and geochemistry of the Foster River mineralization and Broken Hill mineralization.
Wildcat’s objectives for its 2008 summer activities were twofold: a) to confirm the continuity, and if possible to extend the confirmed length, of the mineralized host rock layer between several well documented but isolated Zn-Pb occurrences and b) to understand the structure and deformation history of the mineralized layer for use in guiding the exploration of structurally thickened parts of the minerals’ hostrock.
The mineralized layer was either directly observed or, in absence of direct evidence where obscured by overburden or lakes, through the identification of stratigraphic markers has now been traced for approximately 45 kilometres in a southwesterly direction between Mackie Lake and the Willis Lake occurrence. Along this distance, the quartzite layer hosts twelve Zn-Pb, one Cu and one Au showing. Wildcat’s Foster River property includes most of these mineral occurrences.
In addition, the Company’s geologists recognized several styles of folds that, in places, substantially thickened the mineralized quartzite layer. Critical are F1 shallowly plunging isoclinal folds (isoclinal means that the fold limbs are either parallel to each other or have the same angle) and steeply plunging isoclinal F2 folds. At Sito West, F2 folding may have produced an up to 6-fold thickening of the mineralized quartzite (5 m thickness at a fold limb, up to 30 m thickness at a fold hinge). At Sito East the mineralized layer is probably doubled by F1 folding and overprinted by F2 folding.
The Fable Lake area in the south of Wildcat’s is the site of substantial exposures of mineralized quartzite, two well mineralized glacial boulder trains and extensive, high-contrast Zn, Pb and Ag anomalies detected in the Company’s 2006 mobile metal ions geochemical survey. The boulders, characterized by some of the highest Pb-Zn concentrations recorded on the property (up to 13.2 % Zn and 14.9 % Zn+Pb combined), may be subdivided into two distinct populations, one Zn rich and another dominantly mineralized with Pb. Tracing of the boulder trains to their putative origin, undertaken by Wollex Exploration in 1971, tentatively identified the source of the mineralization in an area covered by the Foster River and alluvial detritus.
In addition to structural geological work, the Company’s geologists collected additional rock sample series to study the presence or absence of an alteration zone in the vicinity of the mineralized layer to prove the close genetic kinship between the large Broken Hill Zn-Pb deposit in Australia and Wildcat’s Foster River deposit. The samples have been shipped to the Iowa State University for analysis.
