Quaterra Releases Results of Fourth Drill Hole at Bear Copper Deposit, Yerington, Nevada
Marketwired
VANCOUVER, BC --(Marketwired - April 06, 2016) - Quaterra Resources Inc. ("Quaterra" or the "Company") (TSX VENTURE: QTA)(QTRRF) and its subsidiary Singatse Peak Services LLC ("SPS") today announced results from Hole B-051, the fourth 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-051, drilled vertically to a depth of 3,878 feet, intercepted 1,483.3 feet (452.1 meters) of 0.26% copper beginning at a depth of 2,191.2 feet. Included within this interval is 1,213.8 feet (370.0 meters) of 0.30% copper starting at 2,191.2 feet. Several narrower intervals shown in the table contain > 0.40% copper with anomalous gold and molybdenum. Hole B-051 is a significant step-out. The nearest holes are B-049, approximately 1,150 feet to the west and historic hole B-22, about 1,300 feet to the southwest.

Discussion
Hole B-051, collared 1,150 feet east of Hole B-049, is the fourth 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. The thickness of the mineralized intercept in B-051 is larger than those in the three previously announced holes of the current drilling program. Bornite also is more common than in previous SPS holes, occurring with chalcopyrite and molybdenite in quartz-sulfide veins, veinlet swarms and stockworks. The quartz-sulfide veins appear to correlate with higher gold and molybdenum values found in B-051 compared to the three previous drill holes. The interval 3,253 to 3278 feet averaged 0.43% copper, 182 ppm molybdenum and 0.12 ppm gold over 25 feet; the interval 2,218 to 2,241.9 feet averaged 445 ppm molybdenum over 23.9 feet.
Each of the three step-out holes drilled during the current program (B-049, B-050 and B-051) have intersected significant copper mineralization, which remains open to the north, northeast and northwest. Hole B-051 was collared more than 1,000 feet from the nearest drill hole. The thick interval of copper mineralization, together with quartz-sulfide veins carrying increased amounts of bornite, molybdenum and gold, highlights the potential adjacent to hole B-051, particularly to the north.

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.
