Micrex Reports on Exploration in British Columbia and New Mexico

EDMONTON, ALBERTA--(Marketwire - July 12, 2007) - Micrex Development Corp. (TSX VENTURE:MIX) -

British Columbia Project

Micrex Development Corp. announced today that it has staked a further 2000 hectares of claims in the Bighorn Project area in northern British Columbia.

This brings the total claim area to over 6200hectares (15,350acres).

Micrex undertook the additional staking on the recommendation of their Geological Consultants based on early results from a recent geophysical survey over the area.

Fugro Airborne Surveys conducted a helicopter-borne magnetic/electromagnetic survey at the property in May of this year.. The 74 square kilometer program was designed to support this year's ground based exploration effort.

Previous work on the property has identified mineralization and structures that Micrex hopes to further delineate with this program.

Micrex considers the Bighorn to be an important exploration target. Limited mining was carried out at Bighorn between 1921 and 1935 on a single quartz vein. The gold bearing vein, called the Lawson Vein, has been traced for a strike length of 920 m. (2990 ft.) and a vertical distance over 460 m. (1495 ft.).

Currently, Micrex and its Geological Consultants are examining the results of the recent airborne geophysical survey at the property in the context of previous exploration results and are prioritizing targets for follow-up investigation. As an example, two veins near the Lawson Vein were identified as anomalous in prospecting by Micrex in 2001 and 2002. Prior results from this anomalous area include gold assays as high as 121.16 g/t (3.9 oz.), silver assays as high as 56.9 g/t (1.83 oz), previously reported in the news release of June 26, 2002. Micrex will be looking for evidence of extensions of these anomalous areas in the airborne geophysics as a guide to further exploration.

Dean Besserer of Apex Geoscience, who is the Qualified Person on this Project, has reviewed this press release.

New Mexico Project

A two-week field program has been completed at the Deadwood/Sunburst project in New Mexico. This was primarily a geological sampling and mapping program on the 19 claims staked in 2006 to the east of the Deadwood/Sunburst Claims.

These new claims cover known historic mines and prospects that have not been evaluated using modern techniques including drilling or geophysics.

A total of 39 rock samples were taken and have been submitted for analysis with results expected around August 1, 2007. The results from this program will be used to direct further exploration including tying in on the drilling program on the adjacent Deadwood and Sunburst claims. That drilling has been delayed until August due to timing constraints by the driller so this program is an important step in getting full use of the drill while on site.

Favourable results from this latest program would be evaluated for further exploration including drilling potential with the aim of allowing drilling to continue once the program at the Deadwood/Sunburst is done.

Mountain Rio Resources Inc., is Micrex's JV Partner and the Operator of this project.
