The natural resource development firm said it had digitised data from 83 old drill holes, 9 cross sections, and an open pit shell at the site.
Red Rock added that it had also recreated a remodelled historic orebody at 2.5% and 1% copper cut-offs and was seeking old core to resample.
The information and calculations from the data would now be handed over to external consultants to assess, who would then advise on any further work required to calculate a JORC-compliant resource.
Andrew Bell, chairman of Red Rock, said the 3-D models of the orebody supported “some assumptions” on which the company had invested in the project, and that the next stage of interpretive work was “still more important, because it will give us grade and tonnage information we can share with the investing public”.
In mid-afternoon trading Tuesday, Red Rock shares were steady at 0.62p.
