Micrex Development Corp.: Update of Drilling Program on the Québec Magnetite Apatite Deposit

Micrex Development Corp. (TSX VENTURE:MIX) is pleased to announce the
progression of the resource definition drilling program on its St. Charles
magnetite deposit in Quebec.


The aeromagnetic survey completed earlier showed at least a 30% increase in the
size of the deposit. All holes were drilled at 45 degrees, while the ore body
dips steeply 80 degrees to the east. Holes are oriented perpendicular to the
magnetite trend.


The drilling has been completed for three holes (SB-11-01 to SB-11-03) and work
is in progress on hole SB-11-04. Preliminary logging of the core suggests
encouraging results. All holes intercepted significant mineralized intersection
of massive magnetite, which is accompanied by abundant apatite. This type of ore
is usually referred as "cumberlandite" in the literature, and is very similar to
the ilmenite bearing counterpart "nelsonite".


Holes SB-11-01 and SB-11-02 were drilled along a profile perpendicular to the
elongated 3 kilometre long magnetic anomaly delineated by the 2011 aeromagnetic
survey. Hole SB-11-01 intersected 28.1 metres (from 66.0m to 94.1m) of
continuous massive magnetite at a core-angle of about 45 degrees. Hole SB-11-02
intersected two intervals of near massive magnetite of 33.9 metres (from 0m to
33.9m) and 18.75 metres (from 58.5m to 77.25m), with a core-angle of 45 degrees.
These intersections suggest a cumulative thickness of at least 20 metres of near
massive magnetite-apatite ore.


Hole SB-11-03 was drilled on a section 75 metres to the south of the previous
drill holes. Preliminary logging indicates an interval of 6.6 metres of
semi-massive magnetite between 63.4m to 70m, followed by more than 10 metres of
apatite-rich massive magnetite from 72.25m to 83.5m. Apatite, in the last
interval, ranges between 25 to 30% in apparent volume with grains of 1-2mm.
Several other metre thick intervals of magnetite ore were also intercepted from
87.5-88.7m, 89.5-91.2m, 104-108.48m, 111.5-112.5m, 120-121.7m and 149-149.5m.


The progression of the program follows the initial plan with each hole 100
metres long and drill pads spaced 100 metres apart.


Micrex is very pleased with the preliminary results of the drilling program
showing the massive magnetite and significant apatite deposits.
