Results of Drilling At The Yerington Copper Project

VANCOUVER - Quaterra Resources Inc. and its subsidiary Singatse Peak Services LLC (SPS) reported the first results from its ongoing 2017 drill program at its Yerington Copper Project including one hole, YM-041A-17, that extends mineralization at least 800 feet below the existing sulfide resource in the Yerington pit

Drilling began on March 26, 2017, to test targets on the Company’s 51-square-mile land package located in the historic Yerington Copper District of Nevada. To date, 12 reverse circulation (RC) holes totaling 9,307 feet and four core holes totaling 8,694.3 feet have been drilled. To lower costs, most holes were begun with RC drilling and completed with core.

The area in and around the historic Yerington pit has been a primary focus. Hole YM-041A-17, drilled at – 55 degrees, intersected 561.7 feet averaging 0.20% copper, including several narrower intercepts with plus 0.30% copper. Hole YM-042-17, also drilled at – 55 degrees, collared in the pit about 1,000 feet further west, intersected a similar but lower grade interval averaging 0.12% copper.

These initial results suggest that the large Yerington mine mineralizing system is open to depth and along strike with potential for higher grades. Two additional holes in the pit, YM-043-17 and YM-044-17, are currently in progress. One hole drilled west of the pit did not intersect significant mineralization.

On January 6, 2014, Quaterra released an updated NI 43-101 resource estimate for mineralization in and around the Yerington pit. Using a cutoff of 0.15% TCu, the measured sulfide copper resource contains 31 million tons averaging 0.33% TCu (205 million pounds of copper), the indicated primary copper resource contains 74 million tons averaging 0.30% TCu (428 million pounds of copper), and the inferred primary copper resource contains 128 million tons of 0.23% TCu (600 million pounds of copper). Mineral resources that are not mineral reserves do not have demonstrated economic viability. Hole YM-041A-17 extends mineralization at least 800 feet below the base of this resource.
