Dia Bras Bolivar Pilot-Mining Program Produced Copper and Zinc for more than US$1 Million in December

MONTREAL, QUEBEC--(CCNMatthews - Jan. 10, 2006) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to announce that during the month of December 2005, it produced US$1,032,000 worth of combined copper and zinc concentrate from its pilot-mining program at the Bolivar mine in Chihuahua, northern Mexico. The production value is based on current copper and zinc prices.

During December, a total of 956 dry metric tons ("DMT") of zinc concentrate and 411 DMT of copper concentrate were produced from 5,837 tons of ore averaging 10.29% Zn and 2.49% Cu. This production was achieved even though the company's mill was closed for eight days during the Christmas holiday. Recovery rates for copper improved from 76.78% in November to 79.95% in December. Zinc recovery rates were constant at 91.72% compared to 91.92% in November. Direct operation costs including shipping of concentrate are estimated at US$680,000 for the month of December. Cash flows from operation are used for exploration and development activities, administrative expenses, capital costs and property payments.

Pilot-mining program:

Since the beginning of its pilot mining program at the Bolivar mine, Dia Bras has produced 6,218 DMT of zinc concentrate and 2,608 DMT of copper concentrate from 50,371 tons of ore averaging 8.07% Zn and 1.89% Cu. The sale of the concentrates produced at the Malpaso mill amounted to US$4.4 million in 2005. Based on a standard concentrate purchase agreement, the totality of the company's concentrate production is being sold currently and throughout 2005, to Marc Rich + Co Investment AG, a privately owned, commodity trading company based in Switzerland.

The Company forecast is milling 22,550 tons of ore at 10-12% Zn and 2-3% Cu in the first quarter of 2006 to produce 3,700 DMT of zinc concentrate and 1,600 DMT of copper concentrate for gross sales of approximately US$4 million. Direct cash operating costs over that period are estimated at US$2.5 million.

The pilot-mining program provides essential costs, logistics, grade, recovery and metallurgical data that will serve for the upcoming feasibility study to be undertaken at the Bolivar property. Dia Bras will continue to drill with two underground rigs at the Bolivar Mine, and with two surface rigs at Bolivar-South, El Gallo and Increible to expand and characterize reserves.

A compilation of 2005 drilling results should be completed and published later this month.
