Quaterra Files Yerington NI43-101 Compliant Technical Report on SEDAR

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 29, 2012) - Quaterra Resources Inc. (TSX VENTURE:QTA)(NYSE Amex:QMM) today announced it has filed with SEDAR a Canadian National Instrument 43-101-compliant technical report on the Yerington Mine portion of the Yerington Copper Project located in Lyon County, Nevada.

The report was prepared by Tetra Tech Inc. of Golden, Colorado, for wholly-owned Quaterra subsidiary, Singatse Peak Services, LLC (SPS), which is exploring and developing the Yerington project.

The report follows an updated resource estimate for Yerington announced in a press release on January 5, 2012 and prepared by Tetra Tech. The technical report also includes a description of the project history, geology, mineralization, drilling, sampling procedures and laboratory Quality Assurance/Quality Control procedures. There are no material differences between the mineral resource estimates in the technical report and the January press release.

The qualified person for the Tetra Tech technical report is Dr. Rex Bryan, Senior Geostatistician for Tetra Tech, Golden, Colorado.

The complete NI43-101-compliant technical report is available at www.sedar.com and on the company website.

On behalf of the Board of Directors,

Dr. Thomas Patton, President and CEO, Quaterra Resources Inc.
