Within the Indicated resources in the Lookout deposit there is a continuous higher grade zone which, at a US$150 NSR cut off, comprises 1.12 million tonnes grading 1.71% copper, 3.21 g/t gold, 3.83% zinc, 62.68 g/t silver.
- 5.6 million tonnes in the Indicated category grading 0.95% copper, 1.75 g/t gold, 1.73% zinc, 29.52 g/t silver; and
- 3.4 million tonnes in the Inferred category grading 0.81% copper, 1.32 g/t gold, 1.29% zinc, 20.10 g/t silver.
Exploration in 2012, involving approximately 15,500 feet of surface drilling, further extended the Trio zone.
Current mineral resource estimates include only the Lookout and Trio deposits, although there are four other known VMS deposits -- Mammoth, Dama, Lindsy and Niblack -- and other exploration potential at Niblack. All of the deposits, including Lookout and Trio, remain open.
