I hardly think 900,000 shares is representative of CBA selling out. That is a ridiculous statement.
CBA have come onto the register after due diligence of a number of factors that relate their mandate for longer term investment outcomes. They don't invest with view to punting on a drill report.
In any case these results indicate that the potential deposit is a significant one with potential for 3-5million oz in the same category as the nearby Kibali deposit with is in excess of 10 million oz and is producing 140,000 oz per quarter.
These results indicate that mineralisation is open at depth (ie it continues beyond the target depth of the recent holes) Trenching indicates that the ore body extends for hundreds of metres with on-surface samples showing high grades and we already know that mineralisation starts at surface across all Lines that have been drilled so far. So this is shaping up and will be drilled for a long time to come. Don't worry about funding, Perseus are there as major shareholders - I'm sure they will be interested to see how big this can get too.
