VANCOUVER, BC --(Marketwired - December 23, 2015) - Quaterra Resources Inc. ("Quaterra" or the "Company") and its subsidiary Singatse Peak Services LLC ("SPS") today announced results from Hole B-049, the second core hole of a drill program to explore and further define the Bear deposit, a large porphyry copper system on the Company's 52-square mile property in the historic Yerington Copper District of Nevada. The drill program is being funded with option payments to SPS by Freeport-McMoRan Nevada LLC ("Freeport Nevada").
Highlights
Hole B-049, drilled vertically to a depth of 3,635 feet, intercepted 1,138 feet (407.9 meters) of 0.26% copper beginning at a depth of 1,588 feet. Higher-grade mineralization, although present, is restricted to narrow zones varying from 3.0 to 5.5 feet in width. This hole extends an already large mineralized system an additional 770 feet to the north. Additional drilling, geology and geophysics are necessary to understand the controls for higher-grade mineralization.

"This is the first step-out hole of our current drilling campaign, and we are pleased with the length of the mineralized intercept, which extends the Bear system an additional 770 feet to the north. The location of higher-grade mineralization in this area is also an important goal of the current program," says Quaterra President and CEO Thomas Patton.
Discussion
Hole B-049, collared 771 feet north of historic Hole B-22, is the second hole of an exploration program designed to corroborate historic assay results, determine geologic controls for higher grade mineralization and attempt to extend higher grade mineralization to the north as suggested by grade-thickness contouring of historic drilling. The thickness of the altered and mineralized zone in Hole B-049 suggests that the Bear system continues to the north and is a large system. Intervals of higher-grade chalcopyrite mineralization (plus 0.7% copper) are associated with silicification and quartz veining ranging in width from 3 feet to 5.5 feet and averaging from 0.72% to 1.38% copper.
The location of significant higher-grade intervals within this large system is one of the objectives of the continuing drill program. To assist in this effort, an IP line to identify possible deep zones of sulphide mineralization was completed on December 18. Results will be available in January.
Hole B-050, located 1,050 feet north-northeast of Hole B-048, is in progress. Drilling has been suspended for the Christmas holidays and will resume on January 7, 2016. Hole locations are shown on a map available on Quaterra's website at http://quaterra.com/bear-drill-holes-nov-12-2015/ . A video of the current drill-program at the Bear deposit is available for viewing on the Company website at http://quaterra.com/quaterra-video-2015-bear-drilling/ . Further results will be reported when available.

Quality assurance and control
Core samples were either sawed or split by SPS personnel in Yerington, Nevada, and shipped to Bureau Veritas Minerals NA - Inspectorate America Corporation, an ISO certified assaying/geochemistry facility, in Reno, Nevada for sample preparation. Gold analyses are assayed in Bureau Veritas' lab in Reno using their "FA430" procedure (fire assay with atomic absorption finish) with a 5 ppb Au detection limit. Prepared pulps are shipped to Bureau Veritas' lab in Vancouver, B.C., Canada, for analysis using their "MA 300" procedure for 35 element ICP-ES analysis. Commercially prepared standards and blanks are inserted by SPS at 50-foot intervals to insure precision of results as a quality control measure. SPS has a chain of custody program to ensure sample security during all stages of sample collection, cutting, shipping, and storage.
