Quaterra's JV Partner Grande Portage Intercepts 8.08 Meters Of 55.53 Grams Per Tonne Gold At Herbert Glacier Project, Alaska

Vancouver, British Columbia--(Newsfile Corp. - September 20, 2012) - Quaterra Resources Inc. (NYSE AMEX: QMM) (NYSE MKT: QMM) (TSXV: QTA) today announced its joint venture partner Grande Portage Resources Ltd. has released additional assay results from seven diamond drill holes on the Deep Trench vein including one hole which also intersected the Main vein at the Herbert Glacier gold project located near Juneau, Alaska.

Hole DDH 311A intersected shallow, high-grade mineralization totaling 8.08 meters of 55.53 grams per tonne gold (1.621 ounces per ton) from 36.06 meters to 44.14 meters, including 3.58 meters of 108.86 grams per tonne gold (3.179 ounces per ton). Additionally, results from the other F Platform holes effectively extend the mineralized envelope of the Deep Trench vein system westward by approximately 40 meters. Please see the table below for details.

Grande Portage says that results of the drilling by the Company in the 2012 season have significantly increased the extent of mineralization by both infill and step-out drilling; discovered new high grade mineralization within the greater mineralized envelope; and, suggested new targets for further exploration.

Says project manager Carl Hale: “In 40 years as a field geologist, the Herbert Glacier is one of the most exciting gold projects I have ever worked on in terms of its potential to become a mine. And we have thousands of meters of veins which have barely been touched.”

To date, all the holes drilled at Herbert Glacier have encountered gold mineralization. Since 2010, Grande Portage has completed 97 drill holes from 15 platforms totaling approximately 13,870 meters of NQ2, NQTW and BQTW diamond drilling, including 51 holes (7,340 meters) drilled in 2012 (most of which assays are still pending). At least 12 more holes are planned before season’s end. Additional drilling will focus on the Main Vein system and the Goat Vein to the north of Deep Trench and the H Pad on the Deep Trench vein, which will be a 110-meter step-out to the east from G Pad.

Twenty new holes, totaling approximately 2,600 meters, were completed in August in a program designed to test the western extent of the Deep Trench vein, which remains open to the west, east and at depth. The assay returns from DDH 12O-1, a 50-metre step-out eastward, demonstrates that the vein system remains open, showing a very strong shear zone with up to 1.925 g/t over 1.05 meters. DDH 12O-1 was drilled from a platform designed chiefly to test the Main Vein system and returned a weighted average gold value of 13.85 g/t over 3.12 meters where it intercepted the Main Vein. Additional discussion of the Main Vein and Goat Vein drilling results will be the subject of future news releases.

In addition to the above values, DDH 311A returned assay results of up to 92.8 g/t Ag, 2.68% Pb, and 1.25% Zn. Silver, lead, and zinc normally only occur in appreciable quantities in the highest grade zones of the vein system.

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.

The Herbert Glacier prospect is in the historic Juneau Gold Belt, formerly a world class district with producers such the A-J and Treadwell mines and many smaller gold mines and prospects. The district has been reactivated by the reopening of Couer Alaska’s Kensington gold mine located northwest of the Herbert Glacier property. Strong community support has also been demonstrated for the Green’s Creek Mine, a massive sulfide deposit containing silver, gold and zinc located in a parallel trend 20 kilometers to the west.

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.
