ABITIBI GRASSROOTS EXPLORATION PROGRAM UPDATE
DIAMOND DRILL PROGRAM UNDERWAY � BOGSIDE PROSPECT
(Cadillac, Qu�bec)

Val-d�Or, Qu�bec � May 28, 2008 - Golden Valley Mines Ltd. (�Golden Valley Mines� or the �Company�) (TSX-V symbol: GZZ) is pleased to report on drilling progress for the Company�s Abitibi Greenstone Belt �Grassroots Exploration Project�.

Diamond Drill Program in Progress � Cadillac, Qu�bec: Diamond drilling is underway at the Bogside Prospect (gold target: map #61 - Kalahari Resources Ltd. Joint Venture property) located in Cadillac Township, Qu�bec. The company will complete three (3) drillholes to test targets outlined by its recent geophysical survey and property compilation.

The property lies immediately southwest of the �Larder Lake-Cadillac Break�, underlain by sedimentary rocks of the Pontiac Group comprised of wacke and mudstone. In the extreme northeast corner of the property, Pich� Group volcanic (komatiite, basalt and andesite) have been previously mapped in contact with the Pontiac sediments immediately to the northeast. The western part of the property is dominated by the Heva Lake Granite that intruded the surrounding Pontiac Group sediments.

Previous diamond drilling (4 DDH�s) has been completed on the property by Camflo Mines Ltd. (Minist�re de l��nergie et des Ressources naturelles documentation technique GM 38093) in 1980-81. Erratic gold values up to 0.23 oz/t gold over 4� were intersected (referred to as �Hamel West� showing area) at the granite-greywacke contact or within granitic dikes associated with silicification and quartz veining. The primary target on the property is an Archean porphyry gold system, consisting of a widespread shell of disseminated gold and pyrite mineralization hosted by diorite porphyry and altered metasediments similar to the Osisko Exploration Ltd. (TSX:OSK) advanced-stage Canadian Malartic gold deposit (a preliminary NI 43-101 compliant inferred gold resource estimate calculation of 8.4 million ounces was reported by Osisko on July 5, 2007).

Three priority and previously untested induced polarization (IP) anomalies have been selected for drill testing.

Previous Drill Programs: Diamond drilling at the Ducros Prospect (nickel-copper-PGE / gold target: map #52) located in Ducros Township, Qu�bec between Senneterre and Lebel-sur-Qu�villon has been completed. Drilling (639-metres) tested seven (7) separate geophysical and geological targets (please refer to the April 17, 2008 press release for details). The core is currently being logged and sampled for analysis.

The Island 27 Prospect (gold target: map #71) located between Kirkland Lake and Matatchewan, Ontario along the �Kirkland Lake-Larder Lake Break� will be drilled next. The property was acquired by Golden Valley Mines following a property due diligence program (refer to press release dated August 23, 2006) following a property submittal by the prospector/vendor (Michael Kilbourne) of the Island 27 claims. The Company has now earned a 100% in the property following expenditures of $100,000. The vendor retains a 2% NSR, of which the Company may purchase half (1%) at any time for $1,000,000.
