So far assay results have been received for 59 RC drill holes within the Central Zone target area, the average down hole drill intersection for all holes is 4.4 metres @ 7.23 g/t Au.

The results show that the grade of the Central zone structure increases towards the northern end of the drill target area as the structure “rolls” into a cross fault. This provides an opportunity to define increased tonnages of exceptionally high-grade mineralisation in close proximity to the surface.
RC drilling is ongoing across the Nabanga discovery area with two rigs currently in operation. The drilling is targeting high-grade gold mineralisation in the North, Central and South target zones that has high potential to support open pit mine development.
Mt Isa is aiming to complete the current drill program on the North, Central and South Zones by March 2012, and subject to receipt of assays and analysis, release a maiden resource estimate for these zones as soon as practicable thereafter.
