Overview
Sonora Gulch is Northern Tiger's principal project. It is located in the heart of the Yukon's Dawson Range - an underexplored part of the larger Tintina Gold Belt. Placer gold mines have operated on streams draining the Sonora Gulch property since the turn of the century, recovering angular nuggets of gold and tetradymite (a bismuth-tellurium mineral). Exploration at Sonora Gulch has indicated the existence of a large and strongly altered system hosting multiple styles of mineralization.

Gold Potential
The gold trend at Sonora Gulch covers 9 square kilometres, and is defined by 1,971 soil samples. Gold-in-soil values range from trace to 2,340 ppb, with an average grade of 56 ppb. Within this broad trend, a number of clusters with significantly elevated gold values have been identified as high priority targets for additional exploration, including the Gold Vein, Sonata and Concerto Creek anomalies.

Porphyry Potential
Also contained within the broad gold anomaly, is a copper-molybdenum anomaly covering a 2 by 1-kilometre area, that is being evaluated as a copper-gold-molybdenum porphyry system. Copper-in-soil values range from trace to 1,870 ppm (443 samples with an average grade of 145 ppm) and molybdenum-in-soil values range from trace to 231 ppm (443 samples with an average grade of 11 ppm).

A number of features commonly considered to be indicative of porphyry systems are evident on the property, including:

age dating done by the Yukon Geological Survey indicate that granitoid intrusions at Sonora Gulch are similar in age to the large Casino porphyry located 40 kilometres to the west;
airborne radiometrics indicate a large zone of potassic alteration in close association with the geochemical anomaly;
the copper-molybdenum anomaly is flanked by three gold zones: the Amadeus Zone to the east, the Nightmusic Zone to the Northwest and the Gold Vein Zone to the Southwest;
widespread gold and base metal skarns have been encountered on the north side of the geochemical anomaly (Nightmusic Zone);
epithermal gold-silver mineralization hosted within a zone of strong argillic and moderate phyllic alteration has been encountered immediately to the east of the geochemical anomaly (Amadeus Zone); and
the geochemical anomaly is hosted in a quartz monzonite stock.

Drilling
In four season, a total of 8,539 metres were drilled in 44 holes. High grade gold has been intercepted in both the Nightmusic and Amadeus Zones - approximately 2 kilometres apart. , including the following significant intercepts:

Nightmusic Zone

Hole SG-08-27 returned a 26.6 metre intercept grading 5.0 g/t gold, 11.9 g/t silver, and 0.23% copper, including a 4.0 metre zone grading 25.8 g/t gold and 6.5 g/t silver.
Hole SG-08-28 returned a 23.0 metre intercept grading 1.3 g/t gold, 21.5 g/t silver and 0.44% copper, including a 5.0 metre zone grading 3.3 g/t gold, 42.1 g/t silver and 1.00% copper.

Amadeus Zone

Hole SG-06-06 returned a 15.3 metre intercept grading 6.2 g/t gold and 3.0 g/t silver, including a 5.0 metre zone grading 12.2 g/t gold and 4.8 g/t silver.
Hole SG-07-12 returned a 64.0 metre intercept grading 1.0 g/t gold and 6.9 g/t silver, including a 4.0 metre zone grading 5.2 g/t gold and 8.3 g/t silver.

What's Next?
A crew has been mobilized to the Company's Sonora Gulch camp to begin line-cutting in preparation for a deep penetrating geophysical survey by Quantec Geosciences Ltd. (the "Titan 24 Survey"). The survey is scheduled for mid-June, and will measure direct current resistivity and induced polarization to depths up to 750 metres. The primary target for the Titan 24 Survey is copper-molybdenum porphyry mineralization.

Following completion of the Titan 24 Survey, Northern Tiger is planning 12 to 15 diamond drill holes (3,000 metres) on the Sonora Gulch property. The drill program is being planned to test the property's porphyry potential as well as one or two of the high-priority gold targets contained within the broader 9 square kilometre gold-in-soil anomaly identified on the property. The drill program is anticipated to begin in late June.

Additional surface exploration, including mapping, prospecting, and geochemical surveys will also be completed to expand and further delineate the mineralized zones at Sonora Gulch.
