Dia Bras Drills 31 Metres of 4.05% Cu and 22.75% Zn at Bolivar Mine

MONTREAL, QUEBEC--(Marketwire - June 7, 2007) - Dia Bras Exploration Inc. (TSX VENTURE:DIB) is pleased to announce more high-grade drill intercepts from its surface exploration and underground drilling program at the Bolivar Mine in the State of Chihuahua, Mexico.

Drill hole DB07B197, an extension type drill hole (see press release of March 1st, 2007) in the El Gallo area intercepted a wide zone of Cu mineralization in the Lower Skarn - magnetite-rich zone. This hole was drilled NE due to the rugged topography in the area, and intercepted an estimated true width of some 12 metres.

This drill hole adds to the resource estimate of the El Gallo area where a 20-hole, 5000 metres drill program has been ongoing since March 2007. The objective of the program is to investigate the potential continuous extent of the Lower Skarn Unit between Mina de Fierro and the El Gallo 1 area that is being explored for low grade - bulk tonnage potential.

More drilling results are expected in the near future.

UNDERGROUND DRILLING

The underground hole was drilled from the mine's level 6 under the Titanic zone and demonstrates down-plunge continuity of the massive sulfide zone. Additional drilling is in progress to determine the extent of this zone, which is readily accessible from the Level 7 workings.
