Micrex Development Corp.: Drilling Program Assay Results from St. Charles Québec

Micrex Development Corp. (TSX VENTURE:MIX) is pleased to announce it has
received 153 assays of magnetite concentrates from Davis tube tests of samples
from its St. Charles de Bourget magnetite project. Davis tube testing is a
routine procedure for magnetite concentration, typically used for iron ore
assaying. St. Charles is a magnetite-ilmenite-apatite deposit, and an average of
7.53% TiO2 is present in the magnetite concentrate, close to the 6-8% expected.
However the titanium distribution is bimodal, with part of the deposit hosting
titanium poor magnetite (1-3% TiO2) and part of the deposit with titanium-rich
(10-16% TiO2) magnetite. Concentrates were clean and within specification,
devoid of deleterious contaminants such as silica (1.27% SiO2), calcium (0.43%
CaO) and magnesium (1.27% MgO).


The presence of portions of the deposit with titanium-poor and titanium-rich
magnetite will enable Micrex to diversify its targeted niche markets for its
magnetite. The titanium-poor magnetite is expected to be suitable for American
producers of iron sulphate for water treatment plants. The American market is
sensitive to the presence of titanium, which is considered a contaminant. For
Canadian producers, however, the titanium-rich sludge produced by the
sulphatation is sold as a value-added by-product. Testing of the material is
currently being carried out by an American sulphate producer. The US sulphate
production represents a market of about $20,000,000 annually. Currently all this
raw product is being supplied from Finland in Europe and is the market that
Micrex intends to pursue.


Micrex also targeted the production of magnetite powder for use as a slurry in
DMS plants of coal mines. This usage is not sensitive to the titanium content of
the magnetite, and will not be affected by the different zones in the deposit.
The market for heavy media for coal mine production is estimated to be about
$22,000,000 annually.


Aside from titanium-poor and titanium-rich magnetite, the St. Charles deposit
also contains similar proportions of ilmenite and apatite, respectively titanium
and phosphate. Co-production of magnetite, ilmenite and apatite is contemplated,
and metallurgical testing in this regard shall be initiated as soon as all
assays are received from the laboratory.


Davis tube testing has been performed by IOS Services Geoscientifiques Inc.
while headgrade and magnetite concentrate assaying has been conducted by
ALS-Mineral from Val D'Or, an ISO-17025 accredited laboratory. Stringent quality
control has been implemented by this IOS certified chemist.


The St. Charles project aims to produce Ti-magnetite for industrial purposes,
with a co-production of ilmenite for the titanium dioxide industry and apatite
for the phosphate industry. Ti-magnetite concentrates are currently being tested
for various applications by potential clients.


This press release has been reviewed and approved by Mr Rejean Girard, P.Geo,
qualified person for the St. Charles project.
