Caledonia Mining has started further drilling the Nama base metal project to identify any potential westerly extension to the mineralized zone and to validate the resource data.

The mineralised zone remains open at depth and to the west.

The project work is estimated to entail ten holes and about 2,100m of drilling and the time period for the completion of the project work will be around five months.

The company has so far drilled 13 of the 18 holes and intersected meaningful mineralization and that includes diamond drilling of six holes covering a distance of2,400m the first phase. The object was to find an upward extension, closer to surface of the mineralized zone identified in the 2011 drilling programme.

By the end of the second phase, a total of 12 holes were drilled covering about 4,970m.

The identified zone was intersected at depths ranging from 80m to 580m below surface and the distance between the drill holes was between 100m and 500m.

The mineralization zone has characteristics that include an estimated 0.52% of weighted average copper grade of samples, estimated mineralized thickness of 10 to 27m and the mineralization extends from the surface to a depth of atleast 580m. The zone has a strike length of about 1,300m and a dip extent of 900m.
