2007-03-05 News Release

Quaterra Resources Inc. reported today that Geotech Ltd. has completed 4,900 line-kilometers of airborne time-domain electromagnetics (VTEM) and magnetic surveying over the company’s Arizona Strip uranium properties. The survey was designed to identify new targets with geophysical signatures that are similar to previously recognized breccia pips.Preliminary results of the survey are encouraging. Not only do known breccia pipes appear as well delineated anomalies, but the survey identified more than 200 moderate to high priority targets with similar geophysical signatures. Joe Inman, Quaterra’s consulting geophysicist, and Condor Consulting Inc., recognized experts in the field of airborne electromagnetics, have been retained to perform a detailed interpretation of the survey results and provide further prioritization of the targets.

Quaterra is the first company to extensively test the VTEM system in the district. The Company began the geophysical survey in December 2006. The program was coupled with helicopter-assisted blanket staking of more than 5,000 new claims that have been selectively perfected to cover most of the high priority anomalies in the center of the uranium district.

“The program has added a new dimension to exploration on the Ariz on St rip,” said VP Exploration Eugene Spiering .“The ability to integrate specific geophysical anomalies with favourabgle surface geology will focus our exploration and give Quaterra a commanding presence in the district, both in terms of land and potential for new discovery.”

Rotary drilling on Quaterras breccia pipe targets began in December 2006 by Barbie Drilling Inc. The program will continue for at least the next six months. Initial drilling has been limited to short stratigraphic holes designed to locate the center or throat of potential breccia pipes. Deep drill holes will be systematically completed to evaluate mineralization in the structures as targets become defined and permitted. At least 8 targets are expected to be tested by deep holes in the current program.

The Ariz ona St rip was one of the most profitable and highest grade ur anium districts in the United St ates during the period from 1980 – 1990. The district produced more than 19 million pounds U3O8 from 7 breccia pipes at an average grade of 0.647% U3O8 and was one of the last hard rock ur anium producers in the US during the price decline of the late 1980s.
