Qualified comments: |
(Applies to: property geology) The zone 5 has 4 different lenses, the longest being 7700 feet and the shortest 1100 feet. The dip is 35-50 degrees north, surface width vary between 25-50 feet.
(Applies to: reserve/resource assays) Estimated grades for the lenses 30-100 % magnetic iron and tonnage of 4 million short tons.
(Applies to: mineralization) Unlike other Shawkey zones, in Zone 5 the magnetite appears to be intrusive type injected into structural features in the gneissic country rock (AR 17004) - remobilized in veins and dykes? |
