Dia Bras reports on high grade lens in the Titanic zone at the Bolivar Mine

Montréal, Québec, - June 27, 2007 -

Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to report on a high grade lens in the Titanic zone along the Fernandez trend of the Bolivar mine  in the State of Chihuahua, Mexico.

“The underground holes were drilled from the mine’s level 6 under the Titanic zone, from which more than 9000 tonnes of high grade mineralized rock had been mined out in 2006. They demonstrate strike and down-plunge continuity of the massive sulfide zone that could be open along strike and down dip”, said Thomas Robyn, Executive Chairman of Dia Bras.

Underground drill holes DB07BM80, 94, 95, and 96 intercepted the new high grade lens at various angles and indicate a SE striking lens dipping at about 300 to the NE, with a minimum thickness of 5 metres. Hole 95, drilled along what could be the longitudinal axis of the mineralized zone, indicates a minimum strike length of 50 metres.  Additional drilling is in progress to determine the extent of this zone and evaluate the potential volume of mineralized material. The zone is readily accessible from Level 7 workings.

Hole DB07BM094, from which an intercept of 31.0 metres averaging 4.05% Cu and 22.75% Zn was reported in a previous press release (see press release #15, June 7, 2007), intersected a further 18.4 metres at 1.3% Cu and 8.0% Zn. This brings the total intercept along the drill hole to 49.4 metres at 3.02% Cu and 17.3% Zn.

Hole DB07BM095, drilled due east and horizontally, intersected 37.2 metres of 1.70% Cu and 1.92% Zn, including a 4.8 metres section averaging 3.68% Cu and 12.84% Zn.  Further down, the hole intersected 3.3 metres of 4.73% Cu and 1.45% Zn.

Hole DB07BM080, intersected 7.0 metres at 2.04% Cu and 16.94% Zn.  This hole intersected the zone some 15 metres below hole 95.

Hole DB07BM096, drilled up section along a NE azimuth, intersected 15.8 metres of 1.92% Cu and 2.00% Zn, including a 5.1 metres interval that averaged 8.55% Cu and 2.22% Zn. This intersection is estimated to be some 10 to 12 metres above hole 95.
