In addition to geochemical sampling and airborne geophysics, 4090 metres of diamond drilling was completed in 2006 prior to Batero Gold's ownership. Fifteen holes were drilled to an average depth of 250 metres. The two deepest drill holes tested the main targets to total depths of 492.7 and 550 metres.

The majority of the drill holes ended in gold mineralization. Indications are that the largest of the intrusions, La Cumbre, continues to the north, south, and east and is open at depth. This porphyry body, measuring 400x400x200 metres, has been successfully tested by five drill holes resulting in the presence of widespread, low grade gold mineralization.

Of the drill holes, a significant discovery was made at La Cumbre from hole DD-8. It intersected 276 metres of 0.75 g/t gold and 0.14% copper from surface to a vertical depth of 150 metres. This intersection was followed up with hole DD-18 which was drilled 250 metres to the south. Significant low-grade gold mineralization was confirmed at surface and intermittently continued to 520 metres depth.

The strike and depth extension of the mineralization intersected in hole DD-8 remains to be systematically tested.
