Strongbow Exploration Inc. (SBW: TSXV) is pleased to announce the first independent NI 43-101 compliant mineral resource estimate for the Main Zone deposit at Strongbow’s wholly owned Nickel King project in southern Northwest Territories.Nickel King Project – Main Zone resource estimate at a 0.2% Ni cut-off (Base Case)
The Main Zone is hosted by two arcuate stacked, moderately south-dipping norite sills (the Upper Sill and the Lower Sill). Mineralization has been traced over a total strike length of approximately 2,600 m and remains open along strike, both down plunge to the southwest and also to the southeast.
“The release of this initial resource estimate for Nickel King confirms the potential of the Main Zone as a near surface, bulk tonnage nickel-copper-cobalt sulphide deposit,” said Ken Armstrong, President and CEO of Strongbow. “The resource has been estimated from a relatively small number of drill holes considering the extensive strike length along which mineralization has been defined. This is reflected in a large portion of the resource falling within the inferred category and further untested potential remains within modelled areas of both the Upper and Lower Sills where drilling density is insufficient to categorize an inferred resource. Additional project upside exists in the form of i) mineralization remaining open along strike from the current mineral resource, ii) untested geophysical targets located both directly along strike and up dip from the Main Zone resource, and iii) the Koona and South Ring prospects, which represent potential near surface satellite deposits located within three kilometres of the Main Zone.”
Petrographic and electron microprobe analytical studies have determined that silicate minerals within the host norite contain very low to negligible amounts of nickel. It is therefore anticipated that nearly all nickel reported in this resource estimate is contained in magmatic sulphide minerals and the use of a lower nickel cut-off grade than the 0.2% Ni base case may be possible. In order to assist in making this determination, Strongbow is commissioning a metallurgical study of the Main Zone utilizing drill core from the 2008 program. Results of this test work, expected by mid summer 2009, will provide Strongbow with initial metallurgical criteria including estimates of grindability, metal recovery and concentrate grade.
