Regional Exploration

Regional exploration continued, identifying and testing numerous prospects throughout FY2015. A systematic strategy of

dropping non-prospective ground has been employed by the joint venture. AngloGold Ashanti is prioritising geological and

structural targets in prospective domains and rock packages to ensure targeted exploration. In total, 774 AC holes (46,514m),

65 RC holes (7,465m) and eight diamond holes (1,312m) were completed in FY2015.

During FY2015, drilling at the Madras prospect, 25km to the south of Tropicana discovered a zone of supergene mineralisation

with a number of highly encouraging intercepts including 15m @ 5.1g/t Au, 25m @ 2.5g/t Au and 17m @ 4.2g/t Au. Encouraging

results were returned at other targets including 4m @ 1.0g/t Au at Scarecrow and 8m @ 0.8g/t Au at Sanpan.
