Wassa
The first stope is blasted at Wassa Underground in July 2016 in the F Shoot zone of the deposit, with commercial
production achieved on January 1, 2017. Development continues and drilling results continue to confirm wide zones
of high grade gold mineralization in the B Shoot.
Prestea
Underground infrastructure refurbishment is largely completed by the end of 2016 and Prestea Underground is
expected to be in commercial production by mid-2017. Alimak stoping is selected as the mining method for Prestea
Underground due to its safety and efficiency benefits.
The Prestea Open Pits deliver substantially higher gold production in 2016 than expected. The mining lease for
the Mampon deposit, which will be mined in 2017, is received. Mampon’s high grade ore will be blended with ore
from Prestea Open Pits to extend the mine life of the Prestea Open Pits into the second half of 2017.
