Dia Bras Announces Results From its Bolivar Pilot-Mining Program for the First Quarter 2008

MONTREAL, QUEBEC--(Marketwire - May 15, 2008) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to report the first quarter 2008 results from its Bolivar pilot-mining program in Chihuahua, Mexico.


- Production value of US$6.9 million in Q1-2008, a 32.69% increase over Q1-2007

- Record production of copper concentrate with 2,249 DMT produced

- Costs improvement contributes to generate a US$3.8 M direct operating cash margin

During the first quarter of 2008, the Company processed 32,595 tonnes of material from the Bolivar Mine property averaging grades of 2.35% Cu and 7.26% Zn, producing 2,249 DMT of copper concentrate and 3,448 DMT of zinc concentrate compared with 30,014 tonnes of material processed, with average grades of 1.34% Cu and 6.77% Zn, producing of 1,172 DMT of copper concentrate and 2,987 DMT of zinc concentrate in 2007.

First quarter production value amounted US$6.9 million, a 32.69% increase over last year's corresponding period value of US$5.2 million. The increase in production value compared to Q1-2007 is mostly attributable to higher copper grades, the strong performance of copper market prices and increased mill throughput. Increased production value from higher zinc grades compared to last year period was offset by the decrease in zinc market prices during the quarter.

A summary of comparative statistics for 2008 and 2007 is shown in the table below.

(1) Non-GAAP measures: The Company reports net smelter production value
(net treatment of refining charges), direct operating cash costs
(including development), direct operating cash margin (FOB Malpaso
mill) and operating cash costs/DMT (including development) even if they
are non-GAAP measures to indicate the approximate value of the year's
sales, and 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) Net smelter production value is calculated using quarterly average
current metal prices which may be different from final prices
(3) Before amortization

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. Total sales during the quarter amounted to US$6.75 million (US$5.69 million in the corresponding period of 2007). Total provisional billings to MRI during the quarter amounted to US$6.9 million. In addition during the quarter, the Company settled negative final billings related to 2006/2007 shipments in the net amount of US$1.1 million.

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 to commercial production. The Company expects to complete sufficient exploration work on the Bolivar property and extensions to start a feasibility study in 2008.

The Company's current cash position is approximately US$3.4 million.
