Quaterra's JV Partner Grande Portage Extends Mineralization on Deep Trench and Goat Creek Veins at Herbert Gold Project, Alaska
Deep Trench vein delivers highest yet recorded assay of 428 g/t (12.5 oz/ton) over 0.71mVANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 11/15/12 -- Quaterra Resources Inc. (TSX VENTURE: QTA) (NYSE MKT: QMM) (NYSE Amex: QMM) today announced its joint venture partner Grande Portage Resources Ltd. has released assay results for the final three holes of its summer/fall 2012 drilling program on its Herbert gold project located approximately 25 kilometers north of Juneau, Alaska. Additionally, the Company has received new metallic screen results, some of which significantly upgrade previously reported values and are listed below.
Drilling has now delineated Deep Trench vein mineralization over a strike length of at least 400 meters. Drill hole 12H-1, an exploration step out 150 meters east of Pad G, intersected a sheared and hydrothermally altered zone over 12 meters in width that hosts gold-bearing quartz with abundant arsenopyrite, an important sulfide associated with gold mineralization. A 1.17-meter interval within this zone averages 5.45 g/t gold. Approximately 700 meters of the Deep Trench vein along strike to the east has not yet been drilled.
Metallic screen assays from previously reported DDH 326B2, drilled on the west end of the Deep Trench vein, increase the bonanza grade intercepts by up to 17%, as shown in the table. The best intercept now contains 0.71 meters (0.38 meters true width) of 428 g/t gold (12.5 oz/ton). This intercept occurs directly below a 2011 trench which contains up to 41.2 g/t gold. Importantly, these occurrences appear to be part of the same high-grade zone or shoot which was intersected by DDH 11E-2 (8.76 meters true width of 37 g/t gold) which suggests that the high-grade shoot has a length of at least 100 meters.
Holes 12J-6 and 12J-7, drilled from Pad J to the southwest on the Goat vein, each contain narrow intervals of 3.75 to 18.25 g/t gold, and extend mineralization to the west.
The following table summarizes the new results from the last three drill holes which have been received since the last news release dated October 31, 2012, plus results from samples which had additional metallic screening work ordered:

Grande Portage is currently working on an updated NI 43-101-compliant resource, scheduled for completion in the first quarter of 2013. The Company is also plotting 2013 drill site locations to be filed later this month as part of its 2013 Plan of Operation. Lastly, the Company reports that it has now completed its second full year of baseline environmental water studies which were independently carried out by Admiralty Environmental, LLC., of Juneau, Alaska.
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 gold 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 gold 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.
