Quaterra Announces Termination of Freeport Nevada’s Membership Interest Option Agreement at Yerington

September 13 2017

VANCOUVER, B.C. — Quaterra Resources Inc. (“Quaterra” or the “Company”) and its subsidiary Singatse Peak Services LLC (“SPS”) today announced that Freeport-McMoRan Nevada LLC (“Freeport Nevada”) has terminated an option to acquire an interest in the Company’s Yerington Copper Project in Nevada. As a result Quaterra now has regained full control over its 100% interest in these assets, allowing an evaluation of emerging opportunities especially in light of the recent increase in the price of copper.

In June 2014, Freeport Nevada entered into a membership interest option agreement (subsequently amended) with Quaterra and SPS granting it the right to earn an initial 55% interest in SPS after providing funds in three stages amounting to US$40.7 million. SPS holds Quaterra’s Yerington District assets.

Up to today’s announcement, Freeport Nevada has provided US$14.54 million in funding that has been used by SPS for exploration, land maintenance, environmental compliance, and G&A on the Yerington property. Exploration work done by SPS during this period has included drilling, geologic mapping and geophysics. The work has extended the large Bear copper porphyry system, discovered additional copper mineralization in, around and beneath the Yerington Pit, and explored for primary sulfide mineralization below the MacArthur oxide deposit. Several untested targets outside areas of known mineralization were also drilled.

“This work to advance the project has been undertaken without dilution to Quaterra shareholders or in the project itself,” says Quaterra Chairman and CEO Thomas Patton. “The Freeport Nevada agreement helped the company through a very difficult period in financial and resource markets. With Freeport Nevada’s exit, Quaterra once again has control over the Yerington Project.”

“With our 100%-ownership position, coupled with recent improvements in market conditions and a rising copper price, we can immediately begin to explore avenues with the potential to create value for shareholders,” he says.

In August this year, Quaterra and SPS announced the first results from the 2017 drill program at Yerington including one hole, YM-041A-17, that extended mineralization at least 800 feet below the existing sulfide resource in the Yerington pit (please see release dated August 2, 2017 on the Company website). The Company will be releasing additional results from this year’s drill program in the coming weeks. It will also be issuing results from the first holes drilled at the Groundhog project, a 40,000-acre property situated on an established copper porphyry belt 200 miles southwest of Anchorage, Alaska, and three miles north of the large Pebble porphyry copper, gold and molybdenum project. Quaterra has an option to acquire a 90% interest in Groundhog.

Quaterra’s Yerington Copper Project is located in the historic Yerington Copper District, about 70 miles southeast of Reno, Nevada. It consists of the Yerington pit sulfide and oxide deposit previously mined by Anaconda; the MacArthur oxide and sulfide deposit; the Bear porphyry copper deposit; and several exploration targets. Quaterra’s 51-square-mile land package is situated in a mining-friendly jurisdiction with a history of copper production and good infrastructure. It also owns valuable water rights in the district.

Quaterra has been active in the Yerington District since 2006, and has released NI 43-101-compliant oxide and sulfide resources at both MacArthur and the Yerington pit, and a preliminary economic assessment at MacArthur.
