Abitibi Grassroots Exploration Program Update
Diamond Drill Program Underway - Cook Lake

Val-d'Or, Qu�bec - March 31, 2008 - Golden Valley Mines Ltd. ("Golden Valley Mines" or the "Company") (TSX-V symbol: GZZ) is pleased to report that drilling at the Cook Lake Prospect has commenced.

Diamond Drill Program in Progress - Kirkland Lake, Ontario: Diamond drilling has started at the Cook Lake Prospect (Gold target: map #54 - Kalahari Resources Inc. - Joint Venture property), located in Grenfell and Teck townships of the province of Ontario, northwest of Kirkland Lake. Drilling will test for both gold (Au) and volcanogenic massive sulphide (Cu-Zn-Ag) targets on the property.

• Airborne Input Anomaly: Two (2) drillholes are planned to test for potential volcanogenic massive sulphide mineralization related to an isolated airborne input anomaly. Overburden in the area has hampered previous surface exploration attempts to explain the causative source of the anomaly that included VLF (very low frequency electromagnetic) geophysical surveying and follow-up channel sampling and rock sampling. No drilling was completed. Recent induced polarization (IP) surveying completed by Golden Valley Mines outlined a strong chargeability anomaly associated with the input response;
• Induced Polarization Anomalies (IP): A series of four (4) drillholes are planned to test moderate to strong and well defined chargeability anomalies across the property. Previous exploration work on the south part of the property identified anomalous gold values associated with gabbro / volcanic contacts and/or related to late fault zones.

Previous Drill Programs: Diamond drilling at the Riviere Lois Prospect (VMS target: map #29) located in northwestern Qu�bec between the villages of Taschereau and Poularies has been completed. Drilling (348-metres) tested three (3) separate geophysical anomalies located within a favourable, and untested, felsic to immediate volcanic sequence within the Hunter Mine Group (HMG) stratigraphy (please refer to the March 14, 2008 press release for details). The core is currently being logged and sampled for.

At the Munro Prospect (VMS target: map #58 - Kalahari Resources Inc. - Joint Venture property), located in Munro Township, Ontario approximately 15-km east of the town of Matheson.  Assay results have now been received for nine (9) of the ten (10) holes. No significant base-metal values were returned from the seven (7) holes targeting the Potter Mine mineralized stratigraphy. The source of the Mega TEM anomaly tested by two (2) drillholes is related to a graphitic argillite unit, weakly anomalous in base-metal mineralization. Assay results for one (1) of the holes remain outstanding. An isolated IP anomaly to the west-southwest of the MegaTEM anomaly was tested by a single drillhole, intersected weakly mineralized volcanic and felsic intrusive rocks A BHPEM (borehole pulse electromagnetic) survey is planned on selective drillholes to test for conductive bodies along the prospective stratigraphy.

The Bejopipa and Bearmac Prospects (Gold target: map #30 and #42) located in the Chapais-Chibougamau area of Qu�bec will be drilled next.
