MONTREAL, QUEBEC--(CCNMatthews - Oct. 10, 2006) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) registered a record 9,113 dry metric tonnes (DMT) in September to close the third quarter 2006 with 23,588 DMT processed and US $7.2 million in concentrate production value at its Bolivar Mine pilot-mining program in Chihuahua, Mexico.

During the quarter ended September 30, 2006, the Company processed 23,588 DMT of material averaging grades of 9.63% Zn and 2.12% Cu, with the month of September contributing for more than 9,100 DMT, the most productive month in terms of tonnage processed since operations began. Recoveries at the Malpaso mill averaged 91.96% for zinc and 85.96% for copper resulting in a production of 3,504 DMT of zinc concentrate and 1,497 DMT of copper concentrate during the third quarter.

The value of total concentrate production based on average monthly zinc and copper prices is estimated at US$7.2 million, which exceeds the early 2006 forecast of US$4.0 million per quarter. Direct operating costs for the quarter, including shipping of concentrate, amounted to US$2.7 million. Sustained high prices for zinc and copper during the quarter combined to result in continued generation of positive cash flow, which finances the exploration and capital expenses as well as property payments.

During the nine-month period ended September 30, 2006, Dia Bras billed a total of US$21.9 million, which included invoices for final settlement for concentrate shipped in late 2005. In the final billing process, the Company continued to benefit from increase metal prices resulting in higher sales of concentrate.

The Company's total concentrate production is sold to MRI Trading AG (MRI), a Swiss-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 that will serve for a feasibility study on the Bolivar property. The short-term objective of the program is to generate sufficient cash flow from zinc and copper concentrate production to finance development and exploration at the Bolivar mine and elsewhere on the Bolivar project.

It is important to note that Bolivar is not at a commercial production stage. The completion of a feasibility study is required to confirm the economic viability of a property before it is brought into commercial production.
