Quaterra Discovers Uranium Mineralized Breccia Pipe on Arizona Strip

High-grade U3O8 discovered in Quaterra's second airborne VTEM anomaly

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 24, 2008) - Quaterra Resources Inc. (TSX VENTURE:QTA)(AMEX:QMM) today announced the discovery of a new breccia pipe with high-grade uranium mineralization on the second VTEM geophysical anomaly tested by drilling on the Company's Arizona Strip Project. Discovery Hole A-20-01, the first hole to test the A-20 anomaly, intercepted a thickness of 34.5 feet averaging 0.37% U3O8 at a depth of 1,442 feet, including a high-grade zone of 6.5 feet averaging 0.63% U3O8 at a depth of 1,443 feet. The hole also intercepted a deeper zone of 13.0 feet averaging 0.46% at a depth of 1,567 feet that includes a higher grade interval of 10.0 feet averaging 0.58% U3O8. A list of all intercepts is shown in Table 1.

"The A-20 pipe is a significant discovery", says Eugene Spiering, Quaterra's VP Exploration. "It may be the first time in the history of the district that the first hole drilled in a target resulted in the discovery of high-grade mineralization in a collapsed breccia pipe."

The relative size of the A-20 pipe cannot yet be determined, but it may be comparable to the larger breccia pipes in the district. Only two holes have been completed in the structure and both have penetrated pipe breccia. Hole A-20-03, drilled as a 10 foot offset to abandoned hole A-20-2, intercepted 11.0 feet averaging 0.21% U3O8 at a depth of 1,548.5 feet. The intercept is at a location approximately 70 feet south of the mineralization in hole A-20-01. Both holes drift to the northeast suggesting that the structure may yet continue for a significant distance to the southwest.

The A-20 target is the second of more than 200 moderate- to high-priority VTEM geophysical anomalies defined on Quaterra's 85 square mile property. Unlike the A-1 structure, A-20 is not a hidden pipe. However, because of its subtle surface expression it remained undetected until Quaterra's VTEM survey. Additional drilling at A-20 will be deferred until later this year. The Company is accelerating testing of additional high-priority VTEM anomalies and is currently drilling a third VTEM target.

(i)In situ uranium grade is expressed as equivalent U3O8 ("eU3O8"). The
grade is calculated using uranium industry standard techniques for gamma
log interpretation which has been found to be an accurate representation of
in-situ grades for uranium mineralization in the district as established by
Energy Fuels Nuclear Inc. during their exploration and mining operations
conducted on the Arizona Strip. Down hole logging was conducted by Strata
Data, Casper, Wyoming with verification by Century Geophysical Corp. The
down-hole gamma logging tools are routinely calibrated by probing
standardized test pits in Grand Junction, Colorado.
