Gramalote is a joint venture between AngloGold Ashanti and B2Gold, where B2Gold is the project operator. Gramalote will be operated as a large-scale high-tonnage open pit mine, with annual ore throughput of 11 Mt/a. On depletion of oxide ore in year 9, up to 15 Mt/a of sulphide ore will be processed. A total of 4.08oz Au is expected to be processed over a 14 year mine life. A preliminary economic assessment update was completed at Gramalote in January 2020, maiden ore reserves (125Mt @0.86g/t containing 3.5Moz Au) have not been altered. The project continues to advance towards a final feasibility study.
