VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 21, 2011) - Quaterra Resources Inc. (TSX VENTURE:QTA)(NYSE Amex:QMM) today announced the appointment of a Vice President and General Manager at the Yerington project which is being explored for copper by its wholly-owned subsidiary, Singatse Peak Services LLC (SPS), in the Yerington Mining District, Lyon County, Nevada.

Steven Dischler, who has 30 years experience in mining and other natural resources, has joined Quaterra as Vice President and General Manager of SPS's Yerington project. He was most recently a Strategy Manager with BP for a portfolio of legacy mines across the U.S., including Yerington. As general manager Mr. Dischler will be responsible for moving the Yerington-MacArthur copper mining complex forward towards production.

Mr. Dischler has held a variety of senior leadership positions in consulting and industry with expertise in permitting and managing major capital projects. His skills include working with regulatory agencies and diverse stakeholder groups in delivery of major projects. Mr. Dischler has been involved with the permitting and development of several major mining projects across the U.S., including the underground sulfide Crandon Mine in Wisconsin, the underground nickel copper Eagle Mine in Michigan and the open pit copper Flambeau Mine in Wisconsin.

Mr. Dischler has a B.S. degree in mining engineering from the University of Wisconsin and M.S. degree in mining engineering from the University of Arizona. He is a registered professional engineer in eight states.

"It is an exciting time to be joining the SPS team at Yerington given the unique opportunity this project has to create jobs for the local community while helping to address the environmental issues from historic mining operations at the site," says Mr. Dischler. "I believe in this project."

Says Quaterra President and CEO Thomas Patton: "Mr. Dischler has extensive experience in all aspects of project development including permitting, project evaluation, engineering, procurement, construction and start-up. His appointment further strengthens our management, operational and development capabilities and positions the Company to move the Yerington-MacArthur copper mining complex forward towards production as quickly as possible."

In April 2011, Quaterra wholly-owned subsidiary, SPS, closed a transaction to purchase all the assets of Arimetco Inc., a Nevada corporation, in the Yerington Mining District of Nevada. Assets include 4.2 square miles of patented claims and fee mineral properties centered on the former Anaconda open pit copper mine containing an historic resource estimate in excess of four billion pounds of copper, and 8,600 acre feet per year of water rights. (Please see important note on historic copper resource estimates below). This property, together with 9.3 and 13.2 square miles of unpatented claims at Yerington and nearby MacArthur respectively, provides the Company with a dominant land position in the center of a prolific and expanding copper camp.
