Coffey Mining Pty Ltd is a Perth based, independent international consulting company specialising in the areas of geotechnical engineering.
The Coffey estimate is based on a geological interpretation from 79
diamond drill holes and 9,036 drill samples. Core recovery averaged 95%. Based on statistical analysis, a high grade cut of 100g/t Au has been applied to 3 metre downhole composites.
Michael Griffiths, Sub-Sahara MD said this is a stunning result for Sub-Sahara"Considering a more selective mining scenario, the grade of the Koka deposit has improved to 6.31g/t from 3.4g/t. We have added a further 250,000ozs to the total global resource. Infill drilling and extension drilling as well as tighter geological controls have delivered a better defined resource, shifting most of the deposit into the "Indicated" status," he said.

"But there is still a lot of upside to Koka with the deposit still open at
depth and to the south, and we have a number of high priority targets to test within the 196km2 concession.
