Base Resources Limited (LON:BSE) has continued to mine successfully at the Kwale mineral sands project such that reserves at the Central Dune were depleted by 11.2mln tonnes of ore containing 790,000 tonnes of heavy mineral, while resources were reduced by 12.8 mln tonnes containing 870,000 tonnes of heavy mineral. At the South Dune, however, resources were increased following infill drilling to give 560,000 tonnes of heavy mineral in the measured and indicated categories, with more inferred.
