Red Rock Resources said it had completed modeling work based on historical data for its Musonoi copper and cobalt project at Kolwize in the Democratic Republic of Congo.
The first-phase development work involved digitising data from 83 old drill holes, 9 cross sections, and an open pit shell.
The information and calculations would now be given to external resource consultants to assess.
'The derivation of a 3-D model that appears to support some of the assumptions on which we invested is an important staging post on our journey,' chairman Andrew Bell said.
'The next stage of interpretive work is still more important, because it will give us grade and tonnage information we can share with the investing public. We aim to start work on this immediately.'
