Micrex Development Corp.: Burmis Drilling Results

EDMONTON, ALBERTA--(CCNMatthews - May 19, 2006) - Mix (TSX VENTURE:MIX) reports today on drilling results from a reverse circulation (RC) drilling program at its Southwestern Alberta Burmis Magnetite Project.

The Burmis magnetite deposits have been tracked in outcrop and with geophysics for over 12 km but with the need to develop sufficient confidence in only a portion of the deposit in order to justify opening a mine Micrex has concentrated its efforts in the more northerly portion of the deposit area. This area offers excellent access and proximity to infrastructure along with over a kilometer of exposed magnetite. This northerly section has the potential to yield up to ten years of mining, allowing Micrex to continue exploring and delineating the remainder of the deposit in greater detail.

The purpose of this particular drilling program was to complete the evaluation of a small portion of the Burmis magnetite deposits along approximately 300 metres of strike length that Micrex has identified as the best place to begin mining. Over two years of potential production are anticipated from this limited but easily accessible area, meaning that the mine footprint can be kept small and with lower impact.

The delay in the reporting of results from the RC drilling program resulted from the closure of the IME testing lab where samples were traditionally being analyzed for total magnetic minerals. This meant that samples had to be sent to an alternative laboratory and that new sample protocols had to be set up and tested extensively prior to conducting the analyses on the RC drillhole samples.

Based upon a testing program, the Saskatchewan Research Council (SRC) was chosen as the laboratory to design a specialized analytical protocol required to analyze the Burmis magnetite samples for the presence of total magnetic minerals. The SRC in conjunction with MIX has designed a suitable and accurate mechanical process that parallels the expected plant processes and gives results for total magnetic minerals in the sample.

The time taken to develop the needed protocols and to run the large number of samples did delay the program results but the data that it has generated is valuable not only for the assays but also as a model of the process to be used in the production facility. Both are essential elements for mine planning and permitting.

A total of 45 RC drillholes yielded 24 intersections of greater than 20 weight percent (wt%) total magnetic minerals. Individual 1 m samples from within the magnetite deposit range from a lowest cutoff of 5 wt% to a high of over 80 wt% total magnetic minerals. Using a cutoff of 5 wt%, the drill tested portion of the Burmis magnetite deposit yields an average of 29.3 wt% total magnetic minerals with an average thickness of 5 m.

A follow up diamond drilling program is being planned to assess the geotechnical aspects of the Burmis magnetite deposits and to obtain specific gravity information. All technical programs for the Burmis magnetite deposits are being conducted under the supervision Michael Dufresne, M.Sc., P.Geol. of APEX Geoscience Ltd., Edmonton, Alberta, a Qualified Person under NI 43-101.
