Quaterra Releases Initial Drill Results From Crestones

2007-07-10 News Release

Quaterra Resources Inc. reported today that an initial six-hole, 3,043-meter core drilling program has been completed at its 100%-owned Crestones property in Durango State, Mexico.

The first drill-holes did not intersect the targeted breccia feeder vents. Subsequent field mapping has identified a series of flat-dipping detachment faults that have offset the outcropping geology an estimated 500 meters to the northeast. The postulated location for the breccia feeder vent(s), based on mapping and drill sections, is southwest of the outcropping breccias in a flat area covered with a thin layer of post-mineral arroyo sediment. An additional 2,000-meter drill program is in progress to test this area.

Says Tom Turner, Quaterra’s Manager of Mexican exploration: “We believe that Crestones is a good place to look for an ore deposit. Based on the size and strength of the alteration system and the widespread weak mineralization observed in outcrop and drill core the project merits continued exploration.”

Assay results have been received for the first five holes, and contain a few low-grade intercepts. All three of the hydrothermal breccia types   the silicified limestone, the quartz porphyry, and the hornfels   contain weakly disseminated sphalerite-galena-sulfosalts. The silica breccia commonly contains minor to 5% disseminated pyrite-marcasite and minor to 5% stibnite. The mixed clast and silicified limestone breccias contain disseminated pyrite-marcasite and minor sphalerite-galena. Coarse sphalerite-galena has been observed in fault gouges. Alteration and mineralization appear to intensify to the southwest.
