Exploration
A drilling program commenced in early 2008, and set out below are the exploration works completed in 2008:
- Drilling holes 8,671 meters;
- Tunneling 1,946 meters ;
- Trenching 500 meters;
- Assay analysis 741pieces;
- Primary halos 1,129 pieces;
- Drill core store 7,844 meters;
- Geological mapping 2 square kilometers;
- Gold reserves and resources have increased by 6.6 tonnes to 41 tonnes, representing an increase of 19.27%.
The initial results have been encouraging, and valuable minerals other than gold were also discovered:
Q4138 - Nine holes drilled, five of them hit gold ore bodies, two gold mineralized structures discovered by three drill holes
