Additional drilling is necessary to evaluate the resource potential of the T-Vein series. Holes ER09-235 to 239, 242 and 243 each intersected high-grade T-Vein intervals at vertical depths ranging from approximately 115 to 225 metres (152 to 283 metres down hole). ER09-236 intersected a one-metre-thick quartz-tourmaline vein containing 40 grains of visible gold grading 25.80 g/t Au, 50 metres down-dip from ER08-118, which assayed 29.74 g/t Au across a 1.50 metre interval. ER09-237 intersected multiple high-grade T-Vein intervals (T5, T6 and T7) 50 metres down-dip of ER08-145, which returned 24.57 g/t Au over 3.0 metres. ER09-239 intersected 0.83 g/t Au across 12.5 metres down-dip of ER08-136, which assayed 17.99 g/t Au across 4.7 metres and of ER08-148, which returned up to 15.49 g/t Au over 3.0 metres in T Vein intervals.
A total of 21,276 metres (68 HQ drill holes) were drilled in 2009 to expand the Eau Claire gold resource within the upper 300 metres. Over the last two years more than 25% of all vein intercepts drilled contain over one ounce gold per ton. 70% of all gold-enriched vein and schist material intersected at Eau Claire within this period contains one-half (0.50) ounce gold per ton over an average thickness of 1.34 metres.
Within the past 24 months, 500 gold-bearing quartz-tourmaline vein intervals with an average grade of 12.4 g/t Au (0.36 oz/ton), at an average thickness of 1.37 metres, have been intersected within the upper one-third of the deposit. 400 vein intervals contain an average grade of 15.2 g/t Au (0.44 oz/ton); 300 vein intervals averaged 18.4 g/t Au (0.54 oz/ton); 200 vein intervals contain an average of 24.6 g/t Au or 0.72 oz/ton; 100 vein intervals contain 42.6 g/t Au (1.25 oz/ton) and 50 intersections have an average of 66.4 g/t Au or 1.94 oz/ton (Table 2).
The Eau Claire deposit hosts a large number of exceptionally high-grade gold veins, from which three recent cyanidation tests of gravity tailings, completed by SGS Lakefield Research Limited, yielded excellent gold extractions.. The finest grind material (P80 = 20 �m, microns) gave a leach gold extraction of 98% which, when included with the gold recovered from gravity separation, gives a combined recovery of 98.8%. The coarsest grind test completed (P80 = 121 �m) gave a cyanide leach gold extraction of 93% which, when added to the gold recovered by gravity separation, gave an overall gold recovery of 95.7%. Acid base accounting tests confirmed that waste from veins processed at SGS is non-acid generating and therefore does not pose any environmental liability.
The most recent resource estimate for the Eau Claire gold deposit, completed in 2005, was based on 182 gold-bearing vein intercepts. Drilling over the past two years has intersected 500 gold-bearing veins at a significantly higher grade than the previous estimate, within the upper 1/3 of the deposit. A substantial number of the current drill intercepts are from the T-Vein group, which is located north of the previous resource limits.
Definition drilling is still required to evaluate the resource potential of a high-grade vein system in the 850 West Zone and the newly discovered Boomerang Prospect, located approximately one-half kilometre east of the eastern margin of Eau Claire. Continued drilling is also warranted to expand the gold resource within main deposit and T-Vein group of veins at depth. Metallurgical test-work currently underway will be integrated with an updated resource calculation in 2010.Deposit and property scale drilling and surface exploration work is planned to continue throughout the year.
