Update On Current Projects

At Micrex’s Deadwood/Sunburst Joint Venture gold project in New Mexico, Dahrouge Geological Consulting Ltd. has completed a detailed sampling and mapping project in preparation for the upcoming drilling program on the property. Both geological mapping as well as a general survey of the property lines and elevations was carried out. The geological survey has revealed a significant outcrop of high-grade copper mineralization that appears to be fault bounded and approximately one metre in width at the exposure, suggesting a potential vein structure. The occurrence is situated such that it can easily be added to the current drilling plan on the known gold structures.

Micrex has also retained Canadian Mine Services Inc. for drilling contracts in the summer of 2006 of $230,000 on The Bighorn Property in the Atlin area of British Columbia and $120,000 on The Burmis Property in the Crowsnest Pass area of Alberta.
