fiscal concessions have been agreed. The project, which will access the deeper sulphide material, will absorb skilled and experienced personnel from the neighbouring Yatela operation, which is reaching the end of its life, as Sadiola moves from contractor to owner mining. As a result, attributable gold production for the year was 17%

Kobada is near-surface gold project that has a global resource base of over 2.2 Moz of gold. The project is located in Mali, Africa's 3 rd largest gold producing nation, 125 km south of its capital, Bamako. Previous operators completed 1,118 holes and 127,455 m of drilling on the property and completed 3 economic studies, the last one being a feasibility study released in February 2016.

Known as the deep sulphides project (DSP), it is the down deep extension of the Sadiola main pit. Based on the positive pre-feasibility studies, AngloGold Ashanti approved a $9m feasibility study (FS) of the DSP in November 2009. The study was completed in November 2010. Environmental impact assessment (EIA) is currently underway and the preliminary drilling targets identified to commence ...

Work on the deep sulphide project consisted of orebody modeling which resulted in some of the inferred resource being upgraded to the indicated category. A draft pre-feasibility study on mining and processing the deep sulphide resource was conducted. The study indicated that at the conditions used in the study, the project was only marginally economic. A metallurgical recovery rate of 65% was ...
