Northern Tiger Resources Chip Samples up to 227 g/t Gold at 3Ace Project, Yukon

EDMONTON, ALBERTA -- (Marketwire - July 31, 2012) - Northern Tiger Resources Inc. ("Northern Tiger" or the "Company") (TSX VENTURE:NTR) is pleased to announce that trenching has exposed new high-grade gold mineralization on its 3Ace Project in the southeast Yukon. Eleven continuous one metre chip samples taken along the strike of a new quartz vein exposure in the Sleeping Giant Zone returned from 0.06 to 226.68 g/t gold, with a weighted average of 50.3 g/t gold. Results are pending from both channel samples and seven recent drill holes testing the new discovery.

"We have now located the second zone on the property to host high-grade gold mineralization," says Greg Hayes, President of Northern Tiger. "It is an exciting discovery given the zone's structural and lithological similarities to the Main Zone, and we have redirected the drill to test the new showing."

Based on the tenor of gold mineralization in the new outcrop, additional trenching has also been completed. The new vein segment is now exposed for 25 metres along strike and is estimated to be approximately 3 metres thick. A map and photo of the vein will be posted on the Company's website at www.northern-tiger.com. Additional trenching has also been completed on other Sleeping Giant vein segments, and an extensive set of channel samples has been completed on these new exposures as well. The trenching has also provided additional structural information, and it was determined that drilling completed in 2010 may not have adequately tested the zone (results up to 1.5 g/t gold over 11.9 metres - see news release dated November 25, 2010). As a result, the drill rig was redirected to the Sleeping Giant Zone, and seven holes (366 metres) have been completed with assays pending.

The Sleeping Giant Zone is interpreted to be a series of overlapping (en echelon) massive quartz veins hosted in a shear zone located one kilometre east of the Main Zone where 2011 drilling returned results up to 4.6 g/t gold over 35.0 metres, including 106.2 g/t gold over 1.0 metre (see news release dated October 25, 2011). Individual vein segments, combined with halos of silicified wall rock and quartz stockwork, are up to 25 metres in width. The northeast striking veins are hosted in a north-south striking mineralized trend exposed in an area 125 metres wide by 300 metres long. The Sleeping Giant Zone appears to be structurally similar to the Main Zone, but is exposed over a larger area.

This News Release has been reviewed and approved by Dennis Ouellette, B.Sc., P.Geol., a Qualified Person as defined by NI 43-101. All rock and drill core samples were analyzed by Inspectorate America Corporation of Richmond, British Columbia using 50 gram fire assay and 50-element, 4-acid ICP analysis. When visible gold is noted in drill core samples or regular fire assay values appear abnormally high, the pulp and metallic screen assay method is used to determine the total gold content and gold contents of different size fractions. This is considered industry best practice when dealing with coarse gold mineralization where a nugget effect is suspected. This determination is accepted as the most representative value and is used in the assay database.


Northern Tiger Resources Inc. (TSX VENTURE:NTR) is a Canadian-based resource exploration company focused on gold and copper exploration in the Yukon, where it has a strong portfolio of projects. Drilling in 2011 intersected 4.6 g/t gold over 35.0 metres (including 106.2 g/t gold over 1.0 metre) at the Company's flagship 3Ace Project in southeast Yukon. The Sonora Gulch copper-gold-silver porphyry project in central Yukon also returned significant drill results in 2011, including 0.45 g/t gold and 3.0 g/t silver over 234.0 metres.
