Quaterra Sells Butte Valley, Nevada, Copper Prospect To Freeport-McMoRan Mineral Properties Inc.

Retains the right to acquire 30% working interest in project or a 2% NSR royalty

VANCOUVER, B.C. – Quaterra Resources Inc. today announced the sale of the Butte Valley porphyry copper prospect to Freeport-McMoRan Mineral Properties Inc. (FMMP). FMMP has paid Quaterra US$2 million, with a contingent acquisition bonus of US$1 million possible in the future if FMMP acquires certain additional designated properties in the area. Quaterra also retains the right, if and when FMMP completes a positive feasibility study, to elect to have either a 30% working interest in the project or a 2% NSR royalty.

“The Butte Valley sale is the first of what I hope will be several transactions to monetize the Company’s non-core assets,” says Quaterra’s President Tom Patton. “We have retained substantial upside in the event that FMMP makes a significant discovery.”

Mr Patton said the cash from the transaction will be used to continue work on the Company’s district-scale, 100%-owned Yerington copper project.

Butte Valley is a large, partially explored porphyry copper system located in eastern Nevada about 40 miles north of Ely in north-central White Pine County. The FMMP purchase includes 1,442 unpatented claims staked by Quaterra and assignment of its rights to an additional 41 claims held under lease from a prospecting syndicate.

Quaterra also announced a modification to FMMP’s earn-in requirement on its Southwest Tintic porphyry copper prospect in Juab County Utah. The time for FMMP to complete aggregate expenditures of US$3,250,000 and US$4,725,000 has been extended by one year to August 29, 2013, and August 29, 2014, respectively. As of August 15, 2012, FMMP has spent a total of US$3 million on the project.
