Micrex Development Corp.: Deadwood Mine Electromagnetic Survey Interpretation

Micrex Development Corp. (TSX VENTURE:MIX) is pleased to update its
Deadwood-Sunburst project located in the Mogollon Mining District, Catron
County, New Mexico, about 35 km from the Arizona border, 1.4 km southwest of
Mogollon and 10 km northeast of Glenwood. The project is easily accessed from
the historic town of Mogollon via Highway 180. The property consists of two
patented mining claims (Deadwood and Sunburst) encompassing approximately 14 ha.


According to historic reports prepared before Deadwood Mine was shut down during
World War II, the Deadwood-Sunburst Property hosts a vein-type gold/silver
deposit with average historic grades of 0.127 oz/ton gold and 6.96 oz/ton
silver. Production numbers from the late 1930s report that 82,914 tons of ore
were milled, yielding 10,524 oz gold and 577,129 oz silver. Records on file with
the State of New Mexico show stope widths of over 6 metres in some places.
Historic data indicates that two other parallel vein systems were intersected
during mining, but were never developed.


From February 11th to 18th, 2012, Geotech Ltd carried out a helicopter-borne
Magnetic and Time Domain Electromagnetic survey over the project. The survey was
flown on traverses spaced 50 metres apart with an azimuth of N90 degrees E and
control-lines spaced 500 metres apart and oriented N0 degrees E. A total of 162
line-kilometers were flown.


In April 2012, independent geophysicist Camille St-Hilaire interpreted Geotech's
survey and all available geologic information. The interpretation outlined:




--  Five weakly magnetic contrasting areas. The most imposing magnetic
    contrast consists of a large North-South oriented magnetic strip
    crossing the entire line network. The Last Chance, Deadwood and Eberle
    Mines are exactly located on the eastern limits of this magnetic high.
    This observation could mean that this limit might be a good indicator
    horizon. 
--  Seven presumed faults. These faults, depending on their orientation, are
    distributed following three distinctive networks. The Eberle, Last
    Chance, Confidence, and Deadwood Mines seem to be directly related with
    them. 
--  One wide strip oriented North-South, located in the centre of the block,
    and showing a very high electrical resistivity. This strip of high
    electric resistivity overlaps surprisingly well with the above high
    magnetic susceptibility area. Such a litho-geophysics division might be
    a useful guide for future exploration work. Many of the neighboring ore
    deposits exploited in the past seem to be located at the edge of the
    area of high magnetic susceptibility, and also appear to be linked to
    the presumed fault-networks. 



In view of this interpretation, Micrex is expanding its planned drill program
into the newly identified areas.
