Micrex Development Corp.: Drilling Program Completed at St. Charles Québec

CALGARY, ALBERTA--(Marketwire - May 29, 2012) - Micrex Development Corp. (TSX VENTURE:MIX) is pleased to announce it has completed the last 5 holes which were added to the initial 14-hole campaign and aimed to test the northward and southward extension of the "Grand Saguenay" apatite-ilmenite bearing magnetite mineralization. The program thus totals 19 holes for 3185.1 metres on the wholly-owned St Charles magnetite project.

Table 1 presents a summary of mineralized intersections from the 19 holes. The location of the holes is presented in map 1. The holes SB-11-17, SB-12-18 and SB-12-19, recently completed, intersected the northern extension of the magnetite layer and confirmed the existence of a second layer, between 5 to 10 metres thick, less than 100m west of the main body. The mineralization remains open laterally to the north and at depth.

494 core samples, typically 3 metres in length, were cut with a diamond saw and shipped to ALS-Minerals, an ISO-17025 accredited laboratory. The samples are being assayed for iron, titanium and phosphorous using the X-Ray Fluorescence (XRF) method. Also, 320 of these samples are currently being processed in the IOS laboratory for magnetite recovery by Davis tube testing and density measurement. Upon receipt of assay results, Micrex intends to proceed with a resource estimate for the main magnetite layer.

The president of Micrex, Mr. Stan Marshall, states "I am very pleased with the completion of the drilling and look forward to receiving the 43-101 compliant resource figures". In the meantime, samples of the mineralized material have been sent to prospective customers for assays and private evaluation, with acceptance expected shortly.

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. Micrex has not completed a preliminary economic on this project.

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