African Barrick Gold (ABG) has revised upwards the resource estimate for its Nyanzaga project in Tanzania after working out how to treat the two mineralised zones of the project, Tusker and Kilimani, as a single pit resource.
Since announcing the updated mineral resource for the Nyanzaga project in January 2012, desk-top scoping work has focused on the modelling of the Kilimani near-surface resource, while field activities have focused on continuing geo-technical, hydrology and metallurgical drill programmes to allow the group to better constrain the open pit model. As a result of the addition of the Kilimani resource ABG has been able to re-model the open pit resource, which has resulted in a larger, single pit incorporating both the Tusker and Kilimani resource areas.
