Micrex Development Corp.: St. Charles NI43-101 Report Update

Micrex Development Corp. (TSX VENTURE:MIX) is pleased to announce that
independent consulting geologists, Rejean Girard and Jean-Paul Barrette, P.
Geo., NI 43-101 qualified persons, from IOS Services Geoscientifiques, have
recently conducted a comprehensive field visit of the St. Charles, Quebec,
Magnetite / Titanium / Apatite / Rare Earth / Vanadium deposit as part of the
due diligence required to complete the NI 43-101 compliant report.


The geologists advise that with limited extra drilling should easily confirm
between 10 million to 43 million tons of ore, equal to the historical resource
estimates on the St. Charles deposit. 


The geologists also recommended undertaking after completion of the report an
ultra-high definition airborne magnetometer survey to isolate the deposit's
outer limits, in addition to a definition drill program to further confirm
tonnage. The geologists stated that a 5 hole drill program should immediately
define 2 million tons of ore. 


As previously announced, various industrial consumers and dealers have indicated
interest in the St-Charles magnetite deposit output.


Management looks to delineate larger tonnage as sales and production progress.

This press release has been reviewed by M. Rejean Girard, geologist and head
director of IOS Services Geoscientifiques Inc. and the Company's Qualified
Person for this project under the meaning of NI 43-101.
