Mesa Acquires Arizona Breccia Pipe Targets
| ||Mesa Uranium Corp. (TSX.V: MZU) ("Mesa") is pleased to report that the company has increased its landholdings in the Arizona Strip Uranium District. Thirteen exploration permits have been acquired from the State of Arizona consisting of 7,585 acres (12 square miles) in Mohave and Coconino counties of northern Arizona.|
The area, known as the Arizona Strip district, had historic uranium production of over 20 million pounds at an average grade of 0.65% U3O8. These high-grade underground mines were discovered and mined in the 1980's and contained some of the highest grade and most profitable uranium mines in the United States. The deposit style is referred to as solution-collapse breccia pipes. These pipes were formed when sediments above deeply buried limestone caves collapsed, caving upwards several hundreds of feet, creating a chimney or pipe-like zone of broken rock (breccia). Mineralized fluids moving through this breccia deposited uranium and other metals at certain horizons in grades and quantities sufficient to mine economically.
As a result of these acquisitions Mesa now controls 10,600 acres (16.5 square miles) of prospective land in the Arizona Strip Uranium District.
Current exploration efforts by Mesa geologists consist of mapping, geochemical sampling and aerial photographic interpretation designed to identify drilling targets. Planning is being done for a ground geophysical program this year to aid in the identification of collapse features associated with breccia pipes.
