BMK MacDonald Mines Exploration Ltd

MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) ("MacDonald" or the
"Company") announces results of a ground gravity survey over the Company's VMS
targets on the Butler Property in the Ring of Fire. 


The presence of density anomalies associated with and adjacent to the
feeder/stockwork sulphides intersected to date on Butler 3 suggests either:




--  An increased presence of sulphides or 
--  A different rock type of greater density or 
--  a combination of both 



The measurement of gravity is an effective technique for defining geometry,
structure, and a proven tool in mapping intrusions in sedimentary and volcanic
terrains. The use of ground gravity surveys, have historical success in the
search for volcanogenic massive sulphide (VMS) deposits. The technique has been
attributed to the discovery of the Sunridge Gold Embra Derho deposit in early
2007 (Approx 62.5 m/tonnes) in Eritea. 


The gravity data collected over the Butler property by the Ontario Geological
Survey ("OGS") and Geological Survey of Canada ("GSC") survey confirmed the
Company's interpretation of a large mafic - ultramafic package that exists along
the eastern portion of the property (Butler 5). This insight prompted MacDonald
to utilize the technique over the highly prospective Butler 3 zone. 


Ground Gravity Survey 

At Butler 3, three distinct density anomalies coincident with anomalies from
other geophysical techniques have been identified by Abitibi Geophysics. These
density anomalies add credence to the interpretation of a large VMS system in
the Zone identified as Butler 3. This system is associated with the stringer
materials in diamond drill hole BP11-Cu06 which intersected 167 metres of 0.39%
Cu and 1.13% Zn. Results for Butler 4 and Butler 5 are pending and data
collection continues as exploration is ongoing 


Butler 3 - Characteristics of a Volcanic Hosted Massive Sulphide Deposit (VMS) 

The Butler 3 targets are quantified by the following geological characteristics:



1.  The volume of alteration is exceptional, indicating that a very large
    volume of hydrothermal fluid discharged in this region. 
2.  Butler 3 is contained in a felsic-dominated sequence.  
3.  The alteration zone is Cu-enriched, and the Cu content increases
    stratigraphically upwards towards the mineralized horizon. Cu tenor is
    high (greater than 3%). 
4.  Zinc mineralization is less than expected - indicating a higher
    temperature system (Cu-enrichment). 



Geophysically the targets have physical properties commonly identified with
massive sulphides. These are:




5.  The Butler 3 targets are Electrically Conductive - indicative of
    metallic content 
6.  Elevated magnetic susceptibility - signifying structure and potential
    sulphides 
7.  Dense - suggesting the presence of sulphides 



In summary Butler 3 exhibits a multitude of exploration vectors and proximity
indicators of a VMS system. These include but are not limited to:




--  Geophysical properties - conductive, dense, magnetic. 
--  Mineral zonation - stringer mineralization with elevated Cu values have
    been intersected over significant lengths 
--  Alteration Indicies - the drilling has identified a large alteration
    system with sodium depletion. This is an indication of lateral distance
    from the core of the discharge zone 
--  Mineral chemistry vectors - these are coincident with the geophysical
    anomalies (conductance and density) 
--  Structural controls - the stringer zone is capped by a key marker
    horizon comprised of a siliceous relatively impermeable, black felsic
    unit 



Deep Penetration and High Resolution IP Resistivity Survey 

Insight Geophysics Inc. has been retained to apply their technology over Butler
3, Butler 4, Butler 5 and the Sanderson properties in the Ring of Fire. This
array is currently being utilized in the Ring of Fire by Noront Resources who
have commented on the success of the technique to identify zones of nickel
sulphide in their recent press release.


Preliminary results of this survey over Butler 3 have confirmed chargeability
anomalies coincident with the gravity results. Chargeability measures the
ability of the sub-surface to temporarily maintain an electrical charge -
sulphides are typically chargeable. The survey is expected to be completed in
early March, 2012. 


Drilling Contractor

Drilling on the Butler property is planned for March, 2012. Cyr Drilling
International Ltd., of Winnipeg, MB currently has a drill and all supplies on
site.


Qualified Person

Quentin Yarie, P.Geo., is the qualified person in regard to the technical data
contained within this news release and will be responsible for overseeing all
aspects of the Company's exploration programs. 


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.
