MacDonald Mines Intersects 112 Meters Assaying 0.18% Nickel on James Bay Lowlands Area Property

Massive Sulphide Intersection of 14.3% Combined Zinc and Lead Over 3.0 Meters Deemed Significant

MacDonald Mines Exploration Ltd. (TSX VENTURE: BMK) (MacDonald Mines” or the “Company”) is pleased to release assay results from its Fall 2007 diamond drilling program carried out over its wholly owned McNugget Property, the Hornby Property; jointly owned by MacDonald and Temex Resources Corp. and the MacDonald-Hawk Uranium property, all located in the James Bay Lowlands of Ontario.

Much of the exploration carried out over the McNugget property in the past has focused on volcanic and sedimentary rocks associated with massive sulphide (VMS) style mineralization. MacDonald Mines’ fall 2007 drill program was designed with a two pronged approach. Diamond drill holes were selected to sample various conductors as well as systematically sample specific geological units present on the McNugget property.

The drill programs of 2007 have proved valuable in revealing characteristics of mafic and ultramafic rock sequences on the McNugget property which are potential hosts to nickel – copper mineralization. MacDonald Mines will consider this newly acquired information as they designing their 2008 winter-spring drilling program that will focus on exploring rock types that are lower in the mafic-ultramafic sequence and more likely to host economic concentrations of Nickel-Copper-PGM mineralization.

Highlights of the fall 2007 program are listed in the table below. Of note are the following:

1. Drill hole MN07-46 encountered peridotite throughout its entire 170 meter length and assayed 0.18% nickel over 112.0 meters including 0.20% nickel over 41.0 meters .

2. Drill hole MN07-47 encountered 0.36% Cu, 10.6% Zn, 3.7% Pb and 115 g/t Ag over 3.0 meters.

The massive sulphide intersection in Hole MN07-47 is deemed significant and additional work will be focused on this VMS target.

The extensive nickeliferous intersection in hole MN07-46 certainly indicates MacDonald Mines is in the right part of the stratigraphic sequence to host nickel deposits. Additional work will focus on this widespread horizon in future exploration programs and additional airborne responses will be tested along its strike length.

In addition, the extensive airborne electromagnetic (AEM) surveying carried out over recently staked mining claims contiguous to the McNugget and Big Mac properties, and on joint venture claim blocks in the Noront Resources’ Ni-Cu-PGM discovery area, has been completed. Interpretation of the AEM data is currently underway. The design of the 2008 winter-spring program is strongly considering this new high-resolution airborne data as well as information derived from previous drill programs.

Hornby Property – MacDonald – Temex J.V.

The Hornby Property is located 5 kilometres to the east of the Noront discovery. Ground geophysical surveys defined EM targets with coincident magnetic anomalies. Several of these were drill tested in the latter part of the 207 drill program. Initial interpretations are that these conductive zones are too high in the geological sequence to host nickel deposits. . Additional targets which are lower in the geological sequence have yet to be drill tested.

As a correction to the news release put forth by MacDonald Mines on January 21, 2008, drill holes MN07-46 and MN07-48 were drilled on the 100% MacDonald Mines owned McNugget property. Drill holes H-07-01 and H-07-02 were drilled on the MacDonald/Temex joint venture Hornby property.

MacDonald – Hawk Uranium J.V.

Hole MN07-55 tested Target N-26 which exhibited a strong AEM response with a coincident magnetic anomaly. The hole intersected gabbro and minor granite throughout its length. Disseminated magnetite was encountered over significant core widths. Sulphide stringers explained the EM response. Holes MN07-51 and 53 tested a strong ground EM response and intersected a sequence of gabbro and granite. However, the EM anomaly was not explained by either hole and further study is required
