Rockwell Completes Drilling at Royce Diamond Property

Ronald W. Thiessen, President and CEO of Rockwell Ventures Inc. (TSX-V: RCW; OTC-BB: RCKVF) announces that the Company has completed drilling at the Royce diamond property. The Royce Claims are located 110 kilometres north-northwest of Yellowknife, Northwest Territories.

Pursuant to an option agreement with GMD Resources Ltd. on the Royce Claims, Rockwell completed a two-phase exploration program on the property. Detailed ground geophysical surveys over six target areas were carried out at the heads of the Wheeler Lake kimberlite indicator mineral trains during February and March 2004. The program comprised 345 gravity stations, 12 line kilometres of electromagnetic (NanoTEM) and 60 line kilometres of magnetic surveys. This work outlined a promising geophysical anomaly. Two holes, totaling 155 metres, were drilled to test the anomaly but failed to intersect kimberlite. Due to these results, Rockwell will not be proceeding with its option with GMD.

Rockwell is continuing to assess new prospects for acquisition.
