NEWS-CONTINUED (Latin America Regional News - from p. 14) Vale Receives Environmental License for S11D Vale reported in early July that it obtained the installation environmental license for its S11D iron ore development project in the Carajás region of Brazil. The project has a nominal capacity of 90 million mt/y of iron ore at an average grade of 66.48% iron and is the largest mine development project in Vale's history. Following issuance of the installation environmental license, Vale's board of directors approved full development of the S11D (Africa Regional News - from p. 18) the vertical shaft due to reach a depth of 183 m by year-end. Expanded Tabakoto Mill Achieves Design Capacity Endeavour Mining's mill expansion from 2,000 to 4,000 mt/d at its Tabakoto gold operations in western Mali achieved design capacity in June. The expansion included the addition of a SAG mill, additional CIL tanks and thickener, a gravity tower, an inline leach reactor, and a gold room. Endeavour CEO Neil Woodyer said, "We are very pleased to have completed the mill project, including investments in the mine, processing plant, and railway and port capacity. Total capital expenditures to develop S11D are estimated at $19.671 billion, including $8.089 billion for the mine and plant and $11.582 billion for logistics. The S11D project is based on proven and probable reserves of 4.24 billion mt at an average ferrous content of 66.7%. Cash costs of production (mine, plant, railway, and port after royalties) are estimated at $15/mt. The project is expected to start up in the second half of 2016 and to deliver full capacity in 2018. The new S11D infrastructure will increase Vale's iron ore trans- port capacity to 230 million mt/y and includes a rail spur, new railway sections with dual tracks, rail terminals, and onshore and off-shore port investments. Engineering for S11D was almost complete as of early July 2013, with equipment and services packages for the whole program 23% contracted and firm proposals in place for an additional 45%. Through May 2013, Vale's spending on the project totaled $2.736 billion. Future capital expenditures will extend through the end of the ramp-up in 2018, though spending is expected to be more concentrated in 2014-2016. expansion on plan and on budget. The mill is meeting our expectations, which include increasing our gold production while reducing our unit operating costs. The expanded Tabakoto operation is now producing gold at a rate of approximately 150,000 oz/y." The Tabakoto property is located near Mali's border with Senegal, 360 km west of Mali's capital, Bamako. Ownership is 80% Endeavour and 20% government of Mali. Gold production during 2012 totaled 110,301 oz. Production during 2013 is forecast at 135,000 to 150,000 oz at a cash cost of $880 to $920/oz. Feed to the Tabakoto mill during 2013 is approximately half from the Djambaye open pit and half from the Tabakoto underground mine. Underground mining is by long-hole open stoping and began in early 2012 from two portals at the bottom of the Tabakoto pit. Underground development is under way at the Segala deposit, which hosts approximately half of the property's total resources. The Tabakoto property's proven and probable reserves totaled 712,000 oz as of year-end 2012 at an average grade of 4.6 g/mt gold, with approximately 80% being underground reserves. Resources inclusive of reserves totaled 1.077 million oz measured and indicated and 966,000 oz inferred.
