This should provide some interesting reading for the weekend.

TORONTO, ONTARIO--(Marketwire - Jan. 15, 2010) - MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) ("MacDonald Mines" or the "Company") announces that it has completed a comprehensive review of all exploration work on its properties in the Ring of Fire area of James Bay. The catalyst for this initiative was the emergence of Cliffs Natural Resources ("Cliffs") as an interested party along with Noront Resources ("Noront") in the acquisition of Freewest Resources ("Freewest").

If the impending Freewest shareholders meeting scheduled for January 25, 2010 approves the Cliffs - Freewest transaction then MacDonald Mines believes that this will be the tipping point for renewed exploration in southern James Bay. The total quoted investment required to develop the chromite mine is in the order of $1.5 billion with infrastructure estimated to comprise $700 million of the total. This significantly changes the economics for other potential discoveries and exploration companies such as MacDonald Mines can now encompass a broader range of targets.

Review of Data Indicates Numerous Signatures Similar to Noront and Freewest

MacDonald Mines initiated a total review of its land holdings, and presents its opinions relating to previous drill results and all geophysical data. From the start, MacDonald Mines airborne survey's over all its properties were flown at a minimum of 100-metre line spacing. The resultant quality data in conjunction with new modeling techniques and interpretation, will play a major role in the development of future exploration initiatives.

An in-depth evaluation and re-interpretation of the geology has indicated that the Company's King, Hornby, Richmond, Bay, Adelaide, Wellington and McNugget properties all encompass geology with numerous anomalous geophysical signatures similar to those seen on adjacent Noront, Freewest and Probe properties.

The re-analysis of the Company's existing data by Hadyn Butler, P.Geo. and Randall Salo, P. Geo. was augmented by the addition of Quentin Yarie, P. Geo. who provided an in-depth geophysical perspective. The resulting collaboration and review provided MacDonald Mines with several targets that warrant further exploration work including diamond drilling. MacDonald Mines also employed the services of Dr. Larry Hulbert, D.Sc.,P. Geo. in the analysis of the data.

Hadyn Butler and Dr. Larry Hulbert have extensive experience and knowledge of Archean type mineralization patterns (nickel, gold and VMS) in Northern Ontario and elsewhere. Hadyn Butler has more than 40 years of geological experience and over 30 years consulting experience with the former INCO Ltd worldwide. Dr. Larry Hulbert, is a recognized expert in magmatic Ni-Cu-platinoid exploration and formerly worked at the Geological Survey of Canada with a global focus on nickel deposits.

Hornby Property

MacDonald Mines Hornby Property is located directly southwest of the Freewest land position. The Company believes that after conducting the review of its airborne survey, the Hornby Property has the potential to host the extension of the Freewest chrome deposits.

McNugget Property

A review of the existing data on the McNugget Property has shown that it hosts both geophysical and geological signatures indistinguishable from those of seen on Noront's properties. Of particular interest were the following results from MacDonald's 2007 drill program:

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

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

The extensive disseminated nickeliferous sulphide intersection in hole MN07-46 indicates that appropriate units have a strong potential to host nickel deposits within McNugget. Furthermore, significant anomalous samples of gold, copper and zinc were intersected by reconnaissance drilling.

Re-evaluation of existing borehole locations by Quentin Yarie, P. Geo., indicates that the boreholes were located based on anomalous geophysical responses from Max-Min data collected over airborne VTEM anomalies. Further review of these data sets has indicated that the Max-Min anomalous responses were not coincident with the deeper penetrating VTEM data, suggesting that many of the VTEM anomalies were unlikely to have been adequately tested or explained.

Chromite, Nickel and Base Metals Targeted for February Diamond Drill Program

MacDonald Mines is currently remodeling drill targets for both nickel and base metals based on its new models and re-interpretation of past data and is planning a diamond drill program for February. The Company also intends to further investigate the geophysical anomaly associated with Freewest's chromite discovery during this upcoming diamond drill program.

MacDonald Mines also believes that exploration from 2005 to 2008 may have identified chrome in a number of it's previous drill holes on the McNuggett Property. MacDonald has confirmed these drill locations and will undertake a total analysis of the drill core, with expected completion by the end of January.

MacDonald Mines Exploring Synergistic Opportunities with Key Companies

The Company understands and recognizes the high cost of exploration in the area and these costs will only increase given the likelihood of having to conduct deeper drilling in order to quantify many of its identified targets. Recognizing this, MacDonald Mines will be looking at any synergistic opportunities with key explorers in the region. MacDonald Mines does however feel very strongly that the Company maintain a significant presence and an active exploration role in James Bay.

Ring of Fire Well Mineralized

Hadyn Butler commented as follows, "The greenstone belts of the "Ring of Fire" in northern Ontario are remarkably well mineralized. The combination of nickel sulphide (Ni-Cu-PGE), VMS (Cu-Zn-Ag), chromitite, potentially vanadiferous titanomagnetite, lead and gold is rare. VMS drill intersections in the southern portion of the "Ring of Fire" occur over a distance of at least 70 kilometers in a similar stratigraphic suite - from MacDonald's McNugget Property to Spider/KWG's earlier discoveries north of McFaulds Lake.

Disseminated nickel sulphide found previously by MacDonald on the McNugget Property are located 45 kilometers from, and are in similar stratigraphy to Noront's Double Eagle high-grade Ni-Cu-PGE discoveries - indicating a series of large mafic-ultramafic actively mineralized magma chambers around the nose of the "Ring of Fire." Freewest's chromitites occur in these chambers adjacent to and on strike from very large differentiated mafic-ultramafic chambers that appear to host nickel sulphide, chromitites and vanadium-potential titanomagnetites across MacDonald's properties."

"In short," continues Mr. Butler, "MacDonald appears to have similar stratigraphy and similar drill intersects of mineralization potential. The scale of these mineralized chambers is such that exploration to date has only established their presence and mineralization types. Indeed, current exploration in the Ring of Fire should still be considered due to the large strike length of the pregnant greenstones. Apart from known discoveries, there are many geophysical targets yet to be drilled."

Management Team Adds Vice President of Exploration

Kirk McKinnon, President & CEO is pleased to announce that Quentin Yarie, P.Geo., has formally accepted a key management position with the Company as Vice President of Exploration.

Quentin Yarie, P.Geo., brings over 20 years project management and business development experience. In addition to his most recent position as a Senior management with Geotech Ltd., Mr. Yarie has held positions of increasing responsibility with a number of Canadian-based geophysical service providers. From 1992-2001 Mr. Yarie was a partner of a specialized environmental and engineering consulting group where he managed a number of large projects including the ESA of the Sydney Tar Ponds and the Maritime and Northeast Pipeline project.

Mr. Yarie augments the Company's strong geological consulting team of Hadyn Butler, P. Geo., Dr. Larry Hulbert, D.Sc., P.Geo. and Taiga Consultants by adding a geophysical focus to MacDonald's exploration strategy.
