BMK MacDonald Mines Exploration Ltd

MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) ("MacDonald" or the
"Company") announces the mobilization of a geophysical crew to begin a ground
gravity survey over the Company's VMS, Ni and Cr targets on the Butler Property
in the Ring of Fire. 


The recently released Ontario Geological Survey ("OGS") and Geological Survey of
Canada ("GSC") gravity gradiometer data over the Ring of Fire has been the
catalyst for the Company's renewed interest in the gravity technique as a proven
exploration tool for identifying density variations associated with
mineralization such as VMS, Ni and Cr. The conclusion of the OGS/GSC gravity
gradiometer survey was that it was probable that gravity highs were defining the
package of mafic and ultramafic intrusive and volcanic rocks which host the
chromite mineralization.


The measurement of gravity is an effective technique for defining geometry,
structure, and a proven tool in mapping intrusions in sedimentary and volcanic
terrains. Alteration can also be mapped where geological units of different
density are offset and/or altered. The use of ground gravity surveys, have
historical success in the search for volcanogenic massive sulphide (VMS)
deposits and has been attributed to the discovery of the Sunridge Gold Embra
Derho deposit in early 2007 (Approx 62.5 m/tonnes) as well as satellite
discoveries at Nevsun's Bisha (Approx 40 m/tonnes) both in Eritea.


The Company initiated a detailed interpretation of the available public data
over the known economic discoveries in the Ring a Fire (Cliffs Natural
Resources, Noront Resources, etc.). Part of this process was the development of
models for chrome and nickel. The models consist of geochemical, lithological
and geophysical signatures. The attributes of the known discoveries in the area
were compared to targets both on both our Butler and Sanderson properties with
strong correlations.


The gravity data collected over the Butler property by the OGS - GSC gravity
survey confirmed the Company's interpretation of a large mafic - ultramafic
package exists along the eastern portion of the property. The Company has
drilled through and into some of the magmatic features to corroborate this
interpretation. In 2011 drill hole V05 drilled through a mafic sill consisting
of an upper portion made up of magnetite gabbros, magnetites, and troctolites
passing downward into Fe-rich peridotites with high background chrome
concentrations. The hole was terminated in peridotites so the proportion of
ultramafic materials in these sills is at least equal to or greater than the
mafic material. Dr. Hulbert concludes that "The observed footwall ultramafic
association to the overlying gabbroic rocks and the property wide distribution
of these gabbroic bodies suggests property wide favorability for ultramafic
bodies which host Ni-Cu-PGE and chrome deposits."

The presence of a density anomaly associated with an ultra-mafic sequence would
suggest the presence of a different rock type of greater density (chromite,
magnetite) or the presence of sulphides which are also extremely dense. These
are the same characteristics identified over the main chromite deposits
(Blackbird, Big Daddy, Black Creek, Black Label and Black Thor).


Ground Gravity Survey

While the OGS/GSC gravity gradiometer survey would not likely have the
resolution to define the known deposits in the Ring of Fire, a ground survey
offers much greater resolution. Ground gravity data will be collected over
Butler 3, 4 and 5. At Butler 3 the objective of the survey is to confirm the
presence of a density anomaly coincident with the EM and magnetic target. Butler
3 remains the primary target and the field work will begin there.


At Butler 3, a density anomaly associated with the other geophysical techniques
would add credence to the interpretation of a large inverted VMS system. This
system is associated with the stringer materials intersected in diamond drill
hole BP11-Cu06 which intersected 167 metres of 0.39% Cu and 1.13% Zn. Butler 3
exhibits the following characteristics:




--  The volume of alteration is exceptional, indicating that a very large
    volume of hydrothermal fluid discharged in this region. 
    
--  Butler 3 is contained in an overturned felsic-dominated sequence.  
    
--  The alteration zone is Cu-enriched, and the Cu content increases
    stratigraphically upwards (but structurally downwards) towards the
    mineralized horizon. Cu tenor is high (greater than 3%). 
    
--  Immediately overlying the marker horizon, massive sulfides have been
    discovered at Butler 3, and it's the down-dip extension of these that
    may contain the larger massive sulfide zone which should exhibit a
    gravity anomaly. 



The ground gravity survey is being conducted by Abitibi Geophysics and is
expected to be completed in February, 2012. A drill program will follow upon
completion of the survey and an interpretation of the results.

About MacDonald Mines Exploration Ltd. 

MacDonald Mines is a mineral exploration company with an established exploration
history in the Canadian Northlands. MacDonald Mines has set upon a strategic
direction of exploration with particular focus on nickel, chrome, copper, zinc,
vanadium and titanium in the "Ring of Fire" area of the James Bay Lowlands of
Northern Ontario. 


With over 9 years of exploration in the James Bay Lowlands, the Company has
systematically acquired quality land positions based on a very precise selection
format that utilizes region-wide interpretations completed by geological
consultant Hadyn Butler, P. Geo. MacDonald is now the second largest landholder
in the Ring of Fire and has a proven track record of environmentally and
socially conscious exploration practices. 


MacDonald Mines exploration focus has been on 3 properties - the Butler, the
Semple-Hulbert and the Sanderson. Recent exploration has been focused on the
Butler property, where the Company has identified seven significant zones of
multi-element mineralization, including copper-zinc VMS systems, vandiferous
titano-magnetite and magmatic nickel sulphides.


The Company has established rapport with First Nation Communities in this
region, which has culminated in the signing of exploration agreements with the
Kasabonika Lake and Webequie First Nations.
