Quaterra and Grande Portage Release Intial 2012 Drill Results at Herbert Glacier Gold Project, Alasaka

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 4, 2012) - Quaterra Resources Inc. (TSX VENTURE:QTA)(NYSE MKT:QMM)(NYSE Amex:QMM) today announced its joint venture partner Grande Portage Resources Ltd. has released initial 2012 drilling results from the Herbert Glacier mesothermal vein gold project near Juneau, Alaska.

Results from the Deep Trench vein include two holes with multi-ounce gold intercepts and numerous other significant intercepts that establish continuity between the wider spaced 2011 mineralized intervals.

Highlights include hole 12E-1, which intersected 3.34 meters (true thickness 2.47 meters) averaging 17.79 g/tonne (0.52 oz/ton) gold, including 0.55 meters of 76.8 g/tonne (2.24 oz/ton) gold; and hole 12G-5, which intersected 5.73 meters (true thickness 3.55 meters) averaging 20.1 g/tonne (0.59 oz/ton) gold, including 1.2 meters of 79 g/tonne (2.3 oz/ton) gold. Hole 12G-3 contains a 3.15 meter intercept with a true thickness of 2.05 meters averaging 15.6 g/tonne (0.455 oz/ton) gold and hole 309B includes a 4.07 meter intercept (true thickness 2.60 meters) averaging 11.3 g/tonne (0.331 oz/ton) gold. These assays along with others are supplied in the table below. A map at the end of this release shows the hole locations. The map is also available on the Quaterra website.

The Deep Trench vein occupies an east-west striking shear zone which dips steeply north. Deep drilling from Pads F, E, and G plus shallow drilling from five additional pads has intersected the mineralized vein over a strike length of 370 meters and to a depth of over 200 meters. The vein can be traced at surface over a strike length of 1,000 meters and is open at depth. Holes 12G-3, 12G-5 and several other holes, for which assays are pending, have partially delineated a new high-grade zone or shoot beginning at the surface between Pads E and G and plunging steeply east to a depth of at least 150 meters. Shallow drilling in this area from platform 311 produced core with strong visible gold for which assays are pending.

"We are very encouraged by the initial results from our 2012 drilling program," says Ian Klassen, President of Grande Portage. "Not only have we discovered a new zone of high-grade gold mineralization east of our original discovery on the Deep Trench vein, but we have also confirmed continuity of mineralization between our more widely spaced holes drilled last year."

By August 30, 36 holes totaling 4,900 meters had been completed in 2012 along the western Part of the Deep Trench vein. Grande Portage will continue drilling with two rigs focusing on the Deep Trench, Main and Goat veins.

Core logging and processing of the core for sampling and storage is done at a secure location in Juneau. Analytical testing of the core samples has been conducted by ALS Canada Ltd., with the sample preparation being done in Anchorage, AK, and analysis of the samples by the Vancouver, B.C. laboratory. Methods include metallic screening for coarse gold, fire assays, and multi-element ICP analysis.

Grande Portage and Quaterra Resources have formed a 65/35 joint venture for the further exploration and development of the property with each party bearing their proportionate costs.
