DIA BRAS REALISES ITS MOST PRODUCTIVE MONTH TO DATE FROM ITS BOLIVAR PILOT MINING PROGRAM

Montréal, Québec, - March 6, 2006 -

Dia Bras Exploration Inc. (DIB-V) (the "Company") is pleased to present its monthly update of its Bolivar mine pilot mining program for February 2006.  The Bolivar mine is situated in Chihuahua, northern Mexico.

In February 2006, the Company realized its most productive month in terms of ore tonnage milled. During the month, the Company processed 7,306 dry metric tons (DMT) of ore at its Malpaso Mill. This ore throughput followed a 7,172 DMT volume in January 2006 representing two consecutive months above the 7,000 DMT level. The Malpaso Mill capacity was increased to 300 DMT per day during the last quarter of 2005 and is running smoothly.  Fine tuning of the plant allowed the mill to process over 340 DMT ton per day on several occasions during the month.

A total of 1,331 DMT of zinc concentrate and 383 DMT of copper concentrate was produced from the 7,306 DMT of ore averaging 11.4% Zn and 1.97% Cu during the month of February. Recovery rates were 92.57% for zinc and 78.55% for copper. This resulted in an estimate production value, based on current copper and zinc prices, of US$1,430,000 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 the South Bolivar area and on the Promontorio property, administrative expenses, capital costs and property payments.

The Company’s forecast of 22,500 tons of ore processing at grades ranging 10-12% Zn and 2-3% Cu during the first quarter of 2006 has already been reached at 64%. In February, the grade levels were on target for zinc and just below target for copper, as the Company chose to run some lower grade development ore for a few days, to take advantage of high metal prices.

The Company’s total concentrate production is currently being sold to MRI Trading AG (MRI), a Switzerland based privately owned commodity trading company, pursuant to a standard concentrate purchase agreement. Total billings in February amounted to over US$2,100,000 including a final 10% invoice covering the previous month's shipments of concentrate.

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.

The Company will be presenting at PDAC on Monday March 6 at 2:00. p.m. Come visit us at Booth #4031.
