Grande Portage Resources Intersects High-Grade Gold Mineralization at Herbert Glacier Project

Quaterra Resources, a junior exploration firm, declared that Grande Portage Resources has reported further results from seven diamond holes drilled at the Deep Trench vein in the Herbert Glacier gold project in Alaska. Grande Portage is the joint venture partner of Quaterra Resources.

Grande intersected high-grade near surface mineralization, including 108.86 g/t gold over 3.58 m and 55.53 g/t gold over 8.08 m in hole DDH 311A. The other F platform hoe results expand the Deep Trench vein system’s mineralized envelope towards west by about 40 m.

The 2012 drilling results have considerably expanded the mineralization level by step-out and infill drill programs. These results identified fresh high-grade mineralization in the large mineralized envelope and recommended fresh target areas for additional exploration.

Mineralized gold has been encountered in all drill holes at Herbert Glacier. Since 2010, Grande Portage has been conducting drill programs and has drilled 97 holes, totaling about 13,870 m from 15 platforms, and 51 holes, totaling 7,340 m during 2012.

The company is planning to drill at least 12 additional holes before the end of this season. Further drill program will specifically target the Main Vein system and the Goat Vein located towards the northern part of Deep Trench and the H Pad located at the Deep Trench vein.

Grande drilled roughly 2,600 m, totaling 20 fresh holes, in a campaign during August. The program was specifically designed to examine the west expansion of the Deep Trench vein, which stays exposed at depth and towards east and west. The assay results from DDH 12O-1 show that the vein system stays exposed and indicates a strong shear zone having up to 1.925 g/t gold over 1.05 m.

Quaterra Resources and Grande Portage have established a 35/65 joint venture for the property’s additional exploration and expansion.
