DIA BRAS: SIGNIFICANT EXPLORATION POTENTIAL AT BOLIVAR

Montréal, Québec, - April 26, 2005 -

Dia Bras Exploration Inc. (DIB-V) (Dia Bras or the "Company") is pleased to announce that the company has received the Bolivar field report from Lawrence D. Meinert, Ph. D. Conclusions of Dr. Meinert are that the Bolivar district has significant exploration potential and prospects for further exploration success are high.

Dr. Meinert is a worldwide known expert on skarn deposits. He visited and worked on many on the major skarn deposits in the world and have worked as a consultant for numerous companies and governmental organizations. He wrote more than 100 papers in the scientific literature. He is also the editor of Mineralium Deposita, one of the premier international journals in the field of Economic Geology. After spending 22 years at Washington State University, Dr. Meinert is currently Professor of Geology at Smith College, Massachusetts.

Dr. Meinert recognizes the Bolivar system to be a Cu skarn system with high Zn in distal regions, as opposed to a Zn skarn system. This has several implications for exploration and development in that Cu skarn systems can be much bigger than Zn skarn systems and have greater lateral continuity with many known examples >100 Mt. Cu skarns associated with porphyritic intrusions can be even larger with several known examples such as Bingham, Morenci, and Santa Rita in the 500 Mt range. Features such as brittle fracture and collapse brecciation cemented by quartz, epidote, and sulfides recognized at La Increible mine are similar to some porphyry Cu deposits in Sonora, Mexico.

In order to better understand the skarn system at Bolivar, mineralogical study will be performed by Dr. Meinert. This study will be the foundation of the next exploration program in the Bolivar district.

The report of Dr. Meinert can be found on the website of the Company at www.diabras.com
