Diamond drilling Diamond Drilling is a highly specialized industry used for mineral exploration around the world. Most commonly using wireline and core bits with diamond encrusted matrix.

Significant intersections from past drilling programs include hole LS22 which intersected a 65.8 meter interval grading 0.3% copper, 5.5% lead, 8.7% zinc, 108.7 g/t silver and 1.55 g/t gold. This hole and other significant past drilling results were reported in a previous news release and are posted on the Company's website.

The 2005 program was designed to step out from work done by previous operators of the property and explore for new massive sulphide deposits. In early 2005 existing gravity data was reprocessed using inversion modeling, incorporating geological data from historic drilling data. The drilling conducted in the initial campaign was done on selected density anomalies generated by the inversion model. A total of five anomalies were targeted but only two anomalies were effectively tested by the drilling program due to technical problems with the drilling. A table and summary of 2005 drilling is found below.

Thickness of the Tertiary cover varies from 150m to 225m in the part of the Lagoa Salgada property investigated by drilling to date.

It is thought that the density anomaly may be related to a paleo-topographic high in the basement rocks. LS05040 cored dominantly coarse-grained felsic volcanics. At 309.75m depth the hole passed through a contact into sedimentary rocks. This hole was abandoned due to drilling difficulty at 341.1m, short of the target depth. Additional geophysical modeling is planned using the new drillhole data to refine the model interpretation. LS05041 and LS05041A were abandoned well short of their design depth due to drilling difficulties at the bedrock contact. The anomaly remains untested. LS05042 was drilled to a depth of 560.9m. The hole cut mostly fine grained sediments within the basement volcano-sedimentary rocks. No significant mineralization was encountered, and the geophysical anomaly remains unexplained. Downhole geophysics is planned to further investigate the target. In early 2006 Redcorp Ventures plans to conduct a down-hole geophysical program to test for off-hole targets in LS05038 and LS05042. In addition, basement depth soundings will be conducted over selected regions of the Lagoa Salgada property. This data will be used to further refine the geophysical models and assist in targeting future drilling. The Company considers that the priority density anomalies at the Lagoa Salgada property remain essentially untested and that the potential for discovery of new massive sulphide zones on the property remains high.
