Dia Bras Exploration Inc. (DIB-V) (Dia Bras or the "Company") is pleased to announce the first sale of concentrates (Cu-Zn) and the preliminary results from its pilot mining and development at the Bolivar Mine.

The company’s objective is to mill 9,000 metric tons by September of high grade material at 4% Cu and 20% Zn. These high grade zones around holes 85 and 87 which indicated grades up to 6% Cu and 28% Zn will be reached within 60 days.

Operating Results
Since the start-up in January, the mine has produced 6,900 metric tons. Current production is from only two faces on level 6.  Level 1 will be on stream at the end of April and two more working faces are available. The objective is to mine from five economic faces by July.

Mill start-up is proceeding as planned. From mid-February to March 31, the mill has processed 3,500 metric tons of ore at an average head grade of 2.69% Cu and 7.11% Zn. All ore shipped to the mill was development ore. At the end of March, the mill had been upgraded to 200 tpd. The mill has produced 332 DMT of Zn concentrate and 234 DMT of Cu concentrate from the Bolivar ore.

Dia Bras is pleased to announce that it is proceeding today to the sale of 278 DMT of zinc concentrate (56.5%) and 185 DMT of copper concentrate (28%) for an amount of US$240,000 to Marc Rich + Co Investment.

The expansion of the mill to 300 tpd will begin in May and should be completed by September. The company expects to mill 3,500 tons in April at an average grade of 3% Cu and 9% Zn and 5, 000 metric tons at grades improving to 4% Cu and 20% Zn in the months of May, June, July and August.

Roscoe Postel and Associates from Toronto are gathering the information necessary for a 43-101 report by May. Their representative is now in Chihuahua to assess mine and mill

Exploration and Mine Development
The last drill program tested the New Bolivar South Zone where Cu, Zn, Ag, Au mineralization in skarn was discovered (See results in table below). The current drilling program is targeted in the mine area to increase the size of the higher grade resources readily available by underground workings. Exploration will also continue in the surroundings to evaluate the Lilly, Cascada and Rosario prospects.
