Northern Tiger Resources Identifies Copper-Molybdenum Porphyry Target at Sonora Gulch

CALGARY, ALBERTA--(Marketwire - Feb. 25, 2010) - Northern Tiger Resources Inc. (TSX VENTURE:NTR) announced today that surface exploration work in 2009 identified a large copper-molybdenum anomaly that is currently being evaluated as a copper-moly-gold porphyry system. The copper-molybdenum anomaly is contained within a 6 kilometre by 1.5 kilometre corridor of anomalous gold geochemistry hosting several high priority gold prospects.

"We are enthused about both the size and intensity of the copper-molybdenum anomaly," says Greg Hayes, President of Northern Tiger Resources. "Initial work on the target has demonstrated the presence of many of the classic indicators of a porphyry system, and recent age determinations done by the Yukon Geological Survey showing that the system is equivalent in age to Western Copper Corporation's world-class Casino porphyry further support the target's potential. Our 2010 exploration program will be designed to advance the new porphyry target as well as to continue to explore our highest priority gold targets located on the periphery of the copper-moly anomaly."

The copper-molybdenum anomaly covers a 2 by 1-kilometre area. Copper values in soil range from trace to 1,870 ppm (443 samples with an average grade of 145 ppm) and molybdenum values in soil range from trace to 231 ppm (443 samples with an average grade of 11 ppm).

Recently published data by the Yukon Geological Survey (YGS) in the Yukon Exploration and Geology Review - 2009 indicate that the granitoid intrusions at Sonora Gulch were emplaced between 74 and 75 million years ago - a similar age to the Casino stock where a very large copper-gold-molybdenum porphyry deposit located 40 kilometres to the west contains stated mineral reserves of 4.4 billion pounds of copper, 8 million ounces of gold and 475 million pounds of molybdenum in approximately 1 billion tonnes of ore. Further, the YGS work indicates that the mineralization at Sonora Gulch was deposited over an extended period in multiple phases associated with discrete pulses of late Cretaceous magmatism.

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

- 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.

This News Release has been reviewed and approved by Carl Schulze, BSc, PGeo, and Qualified Person for the property, in accordance with regulations under National Instrument 43-101. All samples were analyzed by ALS Chemex of North Vancouver, British Columbia, Canada using 50 gram fire assay and 35 element ICP analysis. Northern Tiger Resources Inc. also incorporated numerous standard, blank and duplicate samples for quality control purposes.

Northern Tiger Resources Inc. is a Canadian-based resource exploration company focused on the rapidly developing Dawson Range gold-copper mining district in the Central Yukon.
