Trapper Copper-Gold Porphyry Project
The Trapper property covers a large gold-in-soil anomaly. The gold anomaly was established with more than 900 soil samples defining a greater than two kilometre long zone that averages 200 metres in width and remains open ended along strike. Values range up to 18 g/t gold, and reportedly occur within hydrothermal breccias. The gold anomaly is associated with mafic volcanic rocks assigned to the Triassic aged Stuhinni Group that are intruded by diorite and dacitic feldspar porphyry stocks. Extensive iron carbonate-silica alteration suggests that the soil anomaly is associated with a robust large scale hydrothermal system.
In July 2011 the Company commenced diamond drilling at Trapper with one drill, testing the Main Gold zone, which included the historically defined gold-in-soil anomaly. A second drill was mobilized in late summer 2011 to test new targets identified by the ongoing ground-based Induced Polarization geophysical survey, geological mapping/prospecting and soil geochemical program. Positive preliminary exploration results warranted an expansion of the work program to include an airborne geophysical survey across the entire Trapper property and broadening of regional geological coverage. Assay results from 21 grab samples taken along the core of a 3+ kilometre iron-carbonate altered trend that includes the Main zone, returned an average of 1.12 g/t gold, with a high value of 10.25 g/t gold. These results increased the footprint of gold-rich mineralization by over a kilometre of strike, to 2.5 kilometers.
The Trapper property is interpreted to overlie a porphyry complex having a surface geochemical, geophysical and regional alteration signature of over 15 km2. Gold mineralized feldspar porphyry dikes have been drilled in the Main Gold zone, along the southern margin of the main porphyry target. The dikes occur within the gold-rich carbonate altered halo to the porphyry centre. Multiple occurrences of mineralized porphyry and porphyry-associated alteration and mineralization have been identified across more than half of the Trapper property. A total of 8581 metres of diamond drilling was completed in 42 drill holes, testing the Main Gold zone and other targets across an eight square kilometre area.

Table 1: Drill results from gold-mineralized porphyry units
A gold mineralized feldspar porphyry dike was intersected in drill holes TG-11-011 and 014. Visible gold was present along its margin in drill hole TG-11-011. An at- or near-surface feldspar porphyry sill was intercepted in several holes across 2 kilometres of strike, and hosts gold-silver-lead-zinc mineralization where affected by high-angle structures. Higher grades generally occur near the porphyry units’ contacts with host lapilli tuff. Gold-silver-lead-zinc mineralization also occurs within many high angle structures that radiate from the main porphyry centre. Drilling has defined 2.3 kilometres of gold mineralized strike – the Main Gold zone – that remains open to extension to the northwest and southeast, and on a number of cross structures. Porphyry and andesite dikes intrude some of these structures. Semi-massive sulfide stockworks were intersected in three locations across 1.7 kilometres.
