Dia Bras: Bolivar Pilot Mining Program Starts up 2006 on High Note

MONTREAL, QUEBEC--(CCNMatthews - Feb. 6, 2006) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to announce the results of the Bolivar pilot mining program for January 2006. The mine is situated in Chihuahua, northern Mexico and the production is well on track to mill the forecasted 22,500 tons of ore at 10-12% Zn and 2-3% Cu during the first quarter 2006.

In January 2006, the Company benefited strongly from the increasing price of base metals while realizing its best mining and production results since the beginning of the pilot-mining program in the second quarter of 2005. In January, the Company processed 7,172 dry metric tons (DMT) of ore at its Malpaso Mill facility. This is the highest ore throughput achieved since the beginning of the pilot-program and the first time it reached and exceeded the 7,000 DMT plateau. This production level was achieved despite a ball-mill breakdown at the plant which affected production for fourteen days in mid-January. The January production value, based on current copper and zinc prices, is estimated at US$1,500,000 with estimated direct operation costs, including shipping of concentrate, of US$800,000. Cash flows from operations are used for exploration and development activities in South Bolivar and Promotorio, administrative expenses, capital costs and property payments.

During January, a total of 1,508 DMT of zinc concentrate and 482 DMT of copper concentrate was produced from 7,172 DMT of ore averaging 12.9% Zn and 2.58% Cu. Recovery rates were 93.77% for zinc and 75.18% for copper. The company's total concentrate production is currently being sold, to MRI Trading AG, a Switzerland based privately owned commodity trading company, pursuant to a standard concentrate purchase agreement.

The pilot-mining program provides essential data on costs, logistics, grade, recovery and metallurgy data that will serve for a feasibility study to be undertaken at the Bolivar property
