MONTREAL, QUEBEC--(Marketwire - Oct. 19, 2009) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to announce results from its Bolivar and Cusi pilot-mining programs in Chihuahua, Mexico, for the third quarter ending September 30, 2009, and cumulative results for the first nine months of the year.

Bolivar

During the quarter, the Company processed 21,032 tonnes of material from the Bolivar Mine property with grades averaging 2.26% Cu and 12.44% Zn, compared with the third quarter of 2008 when the Company processed 32,727 tonnes of material with grades averaging 1.18% Cu and 5.72% Zn. The third quarter 2009 production of 935,718 pounds of copper and 5,210,398 pounds of zinc represented a 33.92% increase in copper and a 44.62% increase in zinc produced, compared to the third quarter of 2008. The 2009 cumulative nine month production of 2,358,685 pounds of copper and 13,388,545 pounds of zinc represented a 24.03% reduction in copper and a 0.41% increase in zinc produced during the same period of 2008.

Daniel Tellechea, President & CEO of Dia Bras, stated, "Our short term operating strategy for Bolivar is working as originally planned, where grades and recoveries have increased over the last year, as we move to complete the new mill at the Bolivar mine site."

(1) Non-GAAP measures: The Company reports operating cash costs (including 
    development) even if they are non-GAAP measures to isolate the measure 
    of pilot-mining operation cost activities less amortization and 
    depreciation. The Company believes this is useful supplemental 
    information. However, it should not be considered as a substitute for 
    measure of performance prepared in accordance with GAAP.

(2) Before amortization

During the first nine months of 2009, the Company successfully implemented cost reduction programs which resulted in a $4.2 million (40%) reduction of direct operating cash cost for the production at Bolivar, compared to the first nine months of 2008. This cost reduction was achieved by processing lower tonnage with higher grade material, and by reducing ore transportation costs in the first nine months of 2009 by 43.94%, compared to the first nine months of 2008, however, the production remained at almost the same levels.

The Company expects to produce a total of about 2,900,000 pounds of copper and 17,500,000 pounds of zinc in 2009 from the Bolivar mine.

Cusi

During the third quarter of 2009, Dia Bras produced 9,465 ounces of silver, 34,143 pounds of zinc and 22,858 pounds of lead from its Cusi mine, compared with 13,028 ounces of silver, 17,008 pounds of zinc and 128,617 pounds of lead produced in the third quarter of 2008. The cyanidation project to reach 85% recovery of silver is scheduled to commence the production of silver dore on November 15, 2009. Dia Bras continues to grow and develop the resource through ongoing exploration, with an updated NI 43-101 planned to be released by year end.
