Qualified comments: (Applies to: location ) The location of drill hole 82-3 was taken from AR 062194 Map 1 Drill Hole Locations, and transferred to the map by Ford,1982 (Figure 7-3) in the Technical Report of the Roche Bay Magnetite Project (Advanced Explorations, 2007). Also see location of the grid on AR 062194 Fig 2.

(Applies to: mineralization) Sulphide mineralization (percentages unknown) has been reported in some areas of the BIF (core and outcrops) and is dominated by py-po with traces of cpy-asp. Additionally, the presence of trace amounts of gold and silver has also been identified. Testing of samples in 1984 identified detectable gold values in layers which were poor in magnetite and rich in sulphides and iron-bearing silicates from the A & B Zones. The highest gold value from the A Zone was 0.017 oz/ton Au, from Hole 82-3, from a sample of non-magnetic tailings remaining from a sample interval of 12m of iron formation .
Samples data: (1) Sample type: diamond drill; Sample dimensions: tailings of a 12m interval; Sample description: Hole 82-3 non-magnetic tailings
Commodities and grades in order of importance:Au: 0.017 troy ounces/short ton
