Dia Bras Exploration Inc. (the “Company” or “Dia Bras”) announces the results of the application of the Nichromet’s chlorination process to a sample from the Promontario property. A one kilogram random sample from 10 kilograms of surface material was processed with the following results:

Chemical Analysis	Au g/t	Ag g/t	Cu %	As %	S= %
At beginning (A)	3.76	75.0	0.49	0.046	13.7
After removal of sulfur (B)	4.17	85.0	0.51	0.035	0.01
Sterile solid after leaching (C)	0.03	5.74	0.05	0.022	<0.01
Yields [(B-C)÷B]	99%	93%	90%

The values in the pregnant solution are (in mg/l): Au: 0.19; Ag: 3.91; Cu: 221; and As: 1.0. It is to be noted that practically no arsenic is leached out from the sterile which indicates that arsenic is rendered insoluble by the treatment in the form of ferric arsenate.


The Promontorio property in the State of Chihuahua, Mexico contains indicated resources of 625,000 tonnes grading 4.04% Cu, 2.61 g/t Au and 65.79 g/t Ag and inferred resources of 398,000 tonnes grading 3.87% Cu, 2.19 g/t Au and 59.16 g/t Ag for a total of 1,023,000 tonnes of resources at a depth of 100 meters. A drilling program of 15,000 meters will start in July to significantly increase the reserves.
