In 2007, two holes were drilled north of the copper-gold Empress deposit in the Granite Creek zone to determine whether the geological setting present at the Empress continues to the north. Hole 91-43, drilled 191 metres north of the Empress deposit, intersected 3 zones of molybdenum mineralization totalling 26 metres, over a 100 metre width, with an average grade of 0.020 % Mo. Hole 91-49, 57 metres northwest of Hole 91-43 intersected 133 metres of 0.029% Mo from 53 metres to 187 metres including, from 57 to 133 metres, 77 metres of 0.035 Mo. This was followed by 89 metres of 0.23% Cu and 0.007 opt gold. The molybdenite is in intensely altered volcanic rock to 109 metres then altered quartz diorite to 178 metres where it changes to a mixture of altered and unaltered quartz diorite. The area to the north, east and west remains unexplored.
The main objective of the program in the Granite Creek zone in 2007 was to follow the trends of both molybdenum and copper mineralization intersected in Hole 91-49, described above. The Granite Creek zone is 190 metres north of the Empress deposit.
To accomplish the first objective, three of the 2007 holes were drilled northwest, north and northeast of Hole 91-49. Hole 07-58, 70 metres northwest of Hole 91-49, intersected 260 metres of 0.06% copper in granitic rock. While not significant from a mining perspective, it is very important from an exploration context, in that the mineralization could be on the margin of a higher grade zone. Hole 07-59, 60 metres north of Hole 91-49, intersected granitic rock cut by five separate gabbroic-dyke units with widths ranging between 17.7 to 59.1 metres. Again, the granitic rock carries anomalous copper. Hole 07-60, collared 70 metres northeast of Hole 91-49, intersected the following molybdenum mineralization:

The molybdenum bearing granitic rock is a much more highly altered intrusive than the copper bearing granitic rock and contains no magnetite, which occurs in both the granitic intrusive with copper and the mafic dykes in Hole 07-59. Copper mineralization tends to occur below molybdenum mineralization in the Granite Creek zone. One 14.9 metre section in Hole 07-60, from 273.4 to 288.3 metres, assayed 0.19% copper and 0.013 ounces per ton gold. Holes 07-60 and 91-49 were drilled on the western limit of an irregular, ground magnetic low anomaly which the 2007 ground magnetic survey indicates is 465 metres by up to 975 metres in area. One objective of the 2008 drilling program was to further define the trend of the molybdenum mineralization. Three holes were drilled in the area. The zone appears to strike northeast.
