Should have all got out when Bolnisi Gold off loaded Roseby to URL - they could smell a dog when they saw one. Its so low grade and therefore very sensitive to costs. Its not that revovery has gone down, but rather increased costs have knocked out a large proportion of the resource when converted to a mine reserve. ie less of the metal in the ore can be mined and recovered for a profit (because the costs have risen so much) so they leave it behind or exclude it from the reserve and subsequent financial model.
