Quaterra Provides Status Report At SW Tintic, Utah And Peg Leg, Arizona

VANCOUVER, B.C. — Quaterra Resources Inc. today reports that Freeport-McMoRan Mineral Properties Inc. (FMMP) has completed geophysical surveys, surface sampling and mapping, and two phases of drilling on the Southwest Tintic Project located 94 kilometers southwest of Salt Lake City, Utah.

The work has identified a large alteration system, but copper intercepts are typically low grade and narrow. The cost of this work was approximately US$2.25 million. FMMP has fulfilled its obligation to spend US$2 million on exploration by August 29, 2011 and is currently analyzing results to identify additional drill targets.

FMMP completed a total of seven reverse circulation and three diamond core holes, for a total of 4,323 meters, to depths ranging from 122 meters to 1265 meters. Widespread propylitic and quartz-sericite-pyrite, and lesser biotite alteration were intersected, containing generally narrow intervals of low-grade copper mineralization. Drill hole STFM-3 (TD 378 meters) intersected 34 meters of 0.20% Cu starting at 52 meters depth in the Diamond Gulch area, underlain by a zone of weak associated biotite alteration prior to going back into sericite-chlorite-pyrite alteration in lower part of the hole.  Elsewhere, hole STFM-1 intersected 15 meters of 0.22% Cu starting at 107 meters within pyritic, advanced-argillic altered volcanic rocks, followed by quartz-sericite and biotite alteration with isolated short intervals containing 0.1-0.3% Cu.

FMMP has the exclusive right and option to acquire a 70% ownership interest in the Tintic project by making staged exploration expenditures on behalf of the Company totaling US$4.725 million by August 29, 2013. All future exploration expenditures and the property payments under the Earn-In Agreement are optional. 

The Company also announced that FMMP has terminated its option on the Peg Leg copper project in southeast Arizona after drilling one combination rotary/core hole to a depth of 4,157 feet to test a deep IP anomaly. FMMP had an option to acquire 70% of the Peg Leg project subject to certain spending commitments. The project will now revert entirely to Quaterra and the Company will review the FMMP data before deciding if additional work is warranted.
