Vancouver, British Columbia--(Newsfile Corp. - October 26, 2017) - Quaterra Resources Inc. (TSXV: QTA) (OTCQB: QTRRF) ("Quaterra" or the "Company") and its subsidiary Singatse Peak Services LLC ("SPS") today announced results from the last three holes of a 13-hole, 26,056-foot drill program at its Yerington Copper Project. Drilling, which began in March 2017, tested targets across the Company's 51-square-mile land package located in the historic Yerington Copper District of Nevada.

The three holes reported today (YM-043-17, YM-044-17 and YM-045-17) tested the depth extension of mineralization in and around the historic Yerington pit. (For drill hole locations please see map on the Company website at www.quaterra.com/2017-drill-hole-map/). Hole YM-043-17, drilled at - 55 degrees, intersected 1,269.5 feet averaging 0.15% copper, as shown in Table 1. Hole YM-045-17, also drilled at - 55 degrees, collared in the pit about 900 feet further east, intersected several thinner intervals with grades ranging to 0.55% copper, including a shallow oxide zone (See Table 1 below for more details). Hole YM-044-17, drilled on the northwest rim of the Yerington pit at - 50 degrees, intersected several narrow zones of mineralization averaging less than 0.2% copper.

These results, in combination with previously announced holes YM-041A-17 and YM-042-17, have extended sulfide mineralization from 600 to 800 feet below the currently defined resource across a strike length of 4,400 feet. The absence of higher grade mineralization in these widely spaced holes decreases the likelihood that better grades over appreciable widths exist at greater depth below the pit.

Mineralization, primarily chalcopyrite, is hosted in a quartz monzonite-quartz monzonite porphyry complex and occurs as sheeted veins and vein swarms that are steeply dipping and strike northwesterly parallel to the long axis of the pit. Copper grades are directly related to vein intensity and spacing, which vary markedly over short distances.

The 2017 drill program at Yerington was funded with option payments to SPS by Freeport-McMoRan Nevada LLC ("Freeport Nevada"). On September 13, Quaterra announced that Freeport Nevada had terminated its option to acquire an interest in the Yerington Copper Project. As a result Quaterra now has regained full control over its 100% interest in these assets.

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 untested 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 Yerington, and a preliminary economic assessment at MacArthur.

Quality assurance and control

Drilling includes both reverse circulation (RC) and core, contracted to Layne Christensen Company, Chandler, Arizona, which provided both drill rigs. 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.

SPS also engaged a reverse circulation (RC) drill rig in the current program. RC samples were shipped to the Bureau Veritas Minerals NA facility in Reno, Nevada, for sample preparation and analyses following the same procedure and protocol, including inserted blanks and standards, as that of the core samples described above.
