DIA BRAS REPORTS RECENT DEVELOPMENTS AT ITS BOLIVAR PILOT-MINING PROGRAM IN CHIHUAHUA STATE, MEXICO
Dia Bras Exploration Inc. has provided recent results for its continuing development and pilot-mining program at its Bolivar property in Chihuahua, Mexico.
A ramp has been driven from level 1 to level 2 to access the down-dip extension of the Brecha Linda, a high-grade zone of zinc-copper mineralization that the company has been mining since December, 2005. The ramp has accessed high-grade mineralization on level 2 and development of the zone is in progress.
Another ramp has been driven from level 6 toward level 7 with the objective of reaching the chimney-like high-grade Rosario 1, 2 and 3 and Rodolfo Zn-Cu zones approximately 20 metres below level 6. Dia Bras has already mined these zones above level 6. Another 50 metres of ramp is required to reach level 7 and the first Rosario zone, and should be completed before the end of July. These zones continue deeper, as seen in holes 159 and 168, which intersected the down-dip extensions of Rosario 2 and 3. These samples were assayed by Chemex.

While driving the ramp past level 6.5 (1,960-metre elevation), a new zone of massive sulphide ore was encountered, which is 25 metres in length and varies in width from three to five metres. A raise being developed in this new zone has passed through eight metres vertically and is still in ore. Assay results for three channel samples taken over two-metre widths have been received and are shown in the table below. These samples were assayed using the AA method at the company's lab at its Malpaso mill.

Horizontally, the Rosario 1, 2 and 3 and Rodolfo massive sulphide zones and this new zone extend 170 metres on strike and range from three to 10 metres in width. Starting next week, two of the company's underground drill rigs will test the depth extension of this 170-metre strike length of untested high-grade chimneys.
"These results demonstrate the company's ability to discover and develop additional high-grade ore for its Malpaso mill during this pilot mining phase of the Bolivar program. Given the sustained high prices for zinc and copper, the company expects to maintain its positive cash flow during this prefeasibility phase of work at the Bolivar property," stated Dr. Thomas L. Robyn, the company's executive chairman.
Andre St-Michel, engineer and chief operating officer and executive vice-president of Dia Bras, is the qualified person within the meaning of National Instrument 43-101.
