VANCOUVER, BC, June 28, 2011 - Grande Portage Resources Ltd. (TSX-V GPG) ("Grande Portage" or "the Company") is pleased to announce the completion of their first diamond core hole (11E-1) of the 2011 drill campaign at their Herbert Glacier project. The hole is their first to test the western end of the Deep Trench Vein and was successfully completed at 407' (124.05m) T.D.
Project geologist Carl D. Hale had predicted the Deep Trench intersection at about 110 meters in a south-directed -45° drill hole. Including hanging and footwall alteration zones, the vein intersection found was from 342' to 380' (105.5-117.2m) with the midpoint at about 359 feet (110.7m). Strong quartz-veined intervals are found from 352 to 355 feet (108.6 to 110.7m), also 365-368 feet (112.6-113.5m) and 372-377.5' (108.6-109.5m). Initial inspection showed visible gold in several locations throughout the mineralized intercepts.
Split core samples from the zone will be submitted to ALS Minerals Prep lab in Fairbanks, AK for metallic screen (gold) and ICP analyses. Expedited analyses will be requested.
A second drill hole (11E-2) at -60° S from the same platform is underway. The 2011 Pad E holes will augment information gained from hole 10A-4 drilled in2010. Hole 10A-4 discovered about 10 meters of mineralization in the Deep Trench vein about 200 meters eastward along strike from the 11E-1 hole.
The Herbert Glacier project is in the Juneau Gold Belt about half way between the historic A-J Mine at Juneau and Coeur's Kensington Mine. The target of the Herbert project is a series of strong E-W striking gold-quartz veins hosted within a quartz diorite body.
In 2010 Grande Portage entered into an agreement with Quaterra Resources Inc. (TSX-V: "QTA", NYSE Amex: "QMM") wherein GPG has the right to earn a 65% interest in the Property and the Lease by incurring Expenditures on the Property of not less than USD$1,250,000 on or before June 15, 2012. GPG intends to earn its 65% during this summer's drilling program. If Grande Portage acquires an interest, then Grande Portage and Quaterra will form a joint venture for the further exploration and development of the project, with each party bearing their proportionate share of costs, and a dilution formula will be applicable to any non-contributing party to reduce such party's joint venture interest.
This release was prepared by senior GP consultant Charles C. Hawley, Ph. D. with assistance from Carl Hale, QP, and Catherine McClusky, Project Geologist.
Carl Hale, CPG, a geologist of more than 40 years experience, is directing the field program and will act as the qualified person as that term is defined under NI 43-101.
