* Results of PMT-01-04 were previously announced in a press release on October 26, 2004.

Mr. André St-Michel, engineer, from the Company, is the qualified person who supervised the exploration program.

Dia Bras retained the services of Roscoe Postel Associates Inc. in order to carry out an independent study on the Promontorio property and prepare a due diligence report following the guidelines of NI 43-101 on the project. The report is expected by the end of January.

Moreover, Dia Bras is pleased to announce the signature of an option to purchase a 100% interest in the El Magistral property for US$1,000,000 payable in six installments over a five year period; US$50,000 on signing; US$75,000 on the first anniversary; US$75,000 on the second anniversary; US$100,000 on the third anniversary; US$200,000 on the fourth anniversary and US$500,000 on the fifth anniversary.

The property is subject to 1.5% NSR, which Dia Bras can buy back for US$1,500,000.

The El Magistral property occupies 142 hectares and surrounds the Hidalgo and Promontorio properties to the North, East and South. The property covers the remaining of the 3 km long mineralized structure along which is located the Promontorio deposit. The geology of the property is characterized by a large alteration zone with the presence of disseminated sulfides and gold occurrences.

Let us recall that Dia Bras signed the final option agreement for the acquisition of the Promontorio Project on July 21, 2004. According to a report by Mine Development Associates (MDA) of Reno, Nevada, the property contains indicated resources of 625,000 tonnes grading 4.04% Cu, 2.61 g/t Au, 65.79 g/t Ag and inferred resources of 398,000 tonnes grading 3.87% Cu, 2.19 g/t Au and 59.16 g/t Ag for total resources of 1,023,000 tonnes.

A vast program of geological, geochemical and geophysical surveys is underway on the El Magistral property in order to better define new drilling targets. A metallurgical study is also being completed on the high grade Au-Cu intersections.
