New Zone Of Mineralization At Nieves Project

VANCOUVER, BC - Quaterra Resources and 50% joint-venture partner Blackberry Ventures 1, LLC, reported assay results from 16 core holes totaling 5,388.8 meters completed during the fourth quarter of 2007 at their Nieves silver property in northern Zacatecas, Mexico. The program was successful in extending the Concordia high-grade silver vein mineralization and intersected significant new mineralization in the adjacent Arroyo fault, which may be a new mineralized structure or host the faulted extension of the Concordia vein.
Twelve holes tested the Concordia vein system, one of three east-west striking veins systems on the Nieves property. The best mineralized interval is in hole QTA-48 with 47.48 meters averaging 142 g/t silver, 0.13 g/t gold, 0.37% lead and 0.37% zinc, including a 4.67 meter interval with 777 g/t silver (22.7 oz/ton), 0.53 g/t gold, 2.45% lead and 2.20% zinc. Hole QTA-53 cut the highest grade intercept with a 1.22 meter interval averaging 1.8 kg/t silver (52.6 oz/ton), 0.32 g/t gold, 2.06% lead and 0.69% zinc.
Hole QTA-55 was collared 120 meters northeast of hole QTA-48 and tested the junction of the Concordia vein with the Arroyo fault. The mineralized intercept starts at 62 meters and includes 37.6 meters of 108 g/t silver, 0.15 g/t Au, 0.10% Pb and 0.14% Zn. Within this zone is a 3.3 meter interval that averages 331 g/t silver (9.6 oz/ton), 0.29 g/t gold, 0.17% lead and 0.28% zinc. Mineralization consists of sheeted veinlets, and because of its shallow depth and relatively uniform grade has open pit potential. The Arroyo vein-fault system appears to strike northwest with a moderate southwest dip. Additional drilling will be necessary to determine the extent and significance of this mineralization.
