SAMIRA HILL
Operations
2008 vs. 2007
During the year ended December 31, 2008, 1,418,100 tonnes of ore and 4,505,700 tonnes of waste material were extracted from the Samira Main and Libiri pits, resulting in a strip ratio of 4:1. In 2007, 1,595,000 tonnes of ore and 5,604,100 tonnes of waste material were extracted for a strip ratio of 3.5:1.
A total of 1,521,400 tonnes of ore at an average grade of 1.80 g/t was processed in 2008, compared to 1,510,500 tonnes at an average grade of 1.99 g/t for 2007. The decrease in grade is mainly due to the processing of ore from the Libiri pits and stockpiled ore. Libiri pits have an average grade of 1.8 g/t.
The decline in the recovery rate, from 83% for the year ended December 31, 2007 to 79% during 2008, is primarily due to higher levels of graphite in the ore processed from the Samira Main pit during the first
quarter of 2008.
The decrease in gold production is mainly due to the lower grade of ore processed.
Exploration
The main objective of our 2008 exploration program at Samira Hill was to convert part of the Sikia and Libiri Plateau resources into reserves.
During the year, and taking into account the actual reserves and mine life at Samira Hill, the decision was made to postpone exploration. Earlier in the year, generative exploration was carried out such as auger drilling and mapping, which enabled us to identify new drilling targets mainly in the Libiri area.
As at December 31, 2008 our mineral reserves at Samira Hill totalled 631,100 ounces of gold and our resources totalled 1,293,500 ounces.
