Micrex Development Corp.: St. Charles Heavy Media Production Planned

Micrex Development Corp. (TSX VENTURE:MIX) announces an update on the St.
Charles Quebec Magnetite / Titanium / Apatite / Rare Earth / Vanadium deposit.


Previously Micrex announced that a large international company conducted assays
on samples from the St. Charles deposit. In addition to the magnetite, titanium,
apatite and rare earths, those press releases advised that vanadium yielded
0.4%. Another very large company asked Micrex to reconfirm the rare earths in
the deposit through the Saskatchewan Research Council in Saskatoon. This was
done and all previous results have been re-confirmed.


Micrex has been offering magnetite crushed to 1/4 inch for use as an aggregate
in applications such as heavy concrete, but the market demand for powdered
magnetite (called heavy media) is proving to be much greater. Although heavy
media production requires more processing than the crushed product, the
equipment to grind the rock to the requirements of heavy media customers is
readily available.


An additional benefit of the grinding process is that secondary minerals such as
titanium and apatite are released from the rock matrix, and can be separated
from the magnetite. This results in the creation of additional products, the
value of which is greater than the value of the heavy media alone.


In view of the increased revenue potential that will ensue from heavy media
production, the Micrex board of directors has decided to offer the finely ground
material to its customers. The Company has been negotiating with several
organizations who are seeking to acquire heavy media, and expects to announce a
successful conclusion of these negotiations in the very near future.


Micrex Development Corp. (TSX VENTURE:MIX) is a mineral exploration company
based in Alberta, Canada with mining properties in North America. Current focus
is on the St. Charles de Bourget magnetite / titanium / apatite / rare earth /
vanadium property in Quebec.
