As of today, Dia Bras Exploration Inc. (the “Company” or “Dia Bras”) has completed 16 holes representing a total of 3,021 meters of diamond drilling. Drilling was concentrated on the Piedras Verdes property surrounding the ancient Bolivar Mine (Cu, Zn and Ag) which the Company is in the process of acquiring. Two drill rigs are being used on the Piedras Verdes and a third one is planned to start on the San Jose silver property. As of today, the Company has identified 12 different mineralized structures in a radius of five kilometers, of which only five were drill tested. The Company has announced the results of the first seven holes while 408 samples from holes 6, 8, 9, 10, 11, 12, 14, 15 and 16 are being processed at ALS Chemex laboratory in Vancouver.

Assay results from channel samples for three newly identified mineralized structures are listed below:

One drill rig is testing the Bolivar West zone along the west side of the ancient Bolivar Mine (hole 17). This sub-vertical structure with a northwest direction extends over a distance of two kilometers. Holes DIA-11-04 and DIA-16-04, whose results should be available soon, have shown mineralized zones over ten meters thick in a breccia and also at the granite/skarn contact.

The second drill is testing for the first time the El Gallo 2 structure with a northeast orientation located two kilometers east (hole 18). El Gallo 2 is in the same sector as and parallel to El Gallo 1 and El Gallo 3 which were tested by holes 1-2 and 4-5 at the beginning of the program.

Results of hole 2 announced on January 27, 2004 are as follows:

Results of hole 4 announced on March 4, 2004 are as follows:

 

Results of hole 5 announced on March 8, 2004 are as follows:

Seven holes were drilled on the Increible structure (holes 3, 7, 8, 10, 12, 14 and 15). This northwest oriented brecciated zone presents mineralizations over 50 meters thick. Hole DIA-12-04, currently being assayed, has intersected a chalcopyrite, sphalerite, bornite and chalcocite mineralized brecciated zone 48 meters thick. Further drilling is planned in this zone to test the depth extension.

Results of hole 3 announced on February 10, 2004 are as follows:

 

Note:    All samples represent one-meter section.

Hole 7, some 95 meters to the northeast of hole #3, returned 5 meters of 1.8% Cu and 12 g/t Ag at a depth of 35 meters.

The Bolivar North structure is the direct extension of the ancient Bolivar Mine. Drillings 6 and 9 have partially tested this structure. Hole 6 intersected 17 meters at 1.97% Zn and 22.6 g/t Ag, four meters at 1.02% Cu and four (4) meters at 0.55 g/t Au and 29.9 g/t Ag.

The other mineralized structures still to be drilled are:

El Gallo 2 located at the intersection of a two structures oriented respectively northeast and northwest shows outcrops grading between 3% and 8% Cu;

1. La Montura averaging 34 g/t Ag, 3.6% Cu and 7.8% Zn across 6 meters;
2. Central Zone, a large northwest oriented structure not easily accessible, shows outcrops grading up to 29% Zn;
3. La Pequinia, averaging 237 g/t Ag, 3.84% Cu and 0.72% Zn across 6 meters; and
4. Val 1, Val 2 and Val 3, three northwest oriented parallel structures, show outcrops grading between 4% and 6% Cu.

The drilling program is progressing well and over 3,000 meters have been drilled up to now. A fourth drill rig and additional equipment are on their way to Mexico from Canada.
