Quaterra Announces Commencement of Drilling at Groundhog Prospect, Alaska

VANCOUVER, BC--(Marketwired - July 20, 2017) - Quaterra Resources Inc. ("Quaterra" or the "Company") (TSX VENTURE: QTA) (OTCQB: QTRRF) today announced that Chuchuna Minerals Company ("Chuchuna") has commenced a core drilling program of between two and four holes at the Groundhog copper prospect, a 40,000-acre property situated on an established copper porphyry belt 200 miles southwest of Anchorage, Alaska.

Quaterra has an option to purchase a 90% interest in Groundhog. The program is operated by Chuchuna, an Alaskan company jointly owned by Kijik Corporation ("Kijik"), the ANSCA village corporation for the community of Nondalton, and Alaska Earth Sciences ("AES"), an Anchorage-based mineral exploration company.

Holes will be sited to test several shallow IP anomalies identified by historic surveys and 16.5 kilometers of new IP completed by Zonge International during late June and July. The holes are widely spaced across the property forming an equilateral triangle with sides of about 4.5 kilometers. Two of the holes will test anomalies under shallow Tertiary volcanic cover and one hole will test an anomaly under glacial till. These are the first holes drilled in the Groundhog area. Core will be logged and split in Nondalton and shipped to Fairbanks for analysis by ALS Chemex.

Groundhog is located on State of Alaska claims covering the northern extension of a 10-kilometer wide north-northeast trending structural zone that hosts a number of porphyry copper-gold prospects, including the large Pebble porphyry copper, gold and molybdenum project, which is approximately three miles south of the Groundhog claim boundary. Regional magnetic data suggest that geology similar to that at Pebble extends under cover for an additional 30 kilometers northeast from the Pebble deposit.

Quaterra is committed to funding $1.0 million for exploration in the first year of its agreement with Chuchuna, and a minimum of $500,000 in each of the following four years. Quaterra can earn its 90% interest in Groundhog by providing a total of $5 million in funding for exploration over five years, and by paying Chuchuna a lump sum of $3 million by the end of the fifth year. Quaterra has no obligation to exercise its option and can terminate the agreement at its discretion annually. (All amounts are expressed in U.S. dollars). Chuchuna will be the operator of the project and will plan, implement and manage exploration field programs as set out in a budget and work plan approved by Quaterra.
