GPP are not under any "continuous disclosure" obligations reporting holes as they are completed, they have done it to quieten the masses that wanted continuous or regular updates. Problem is, if they stop announcing "holes completed" "moving drill to hole xxx" and a brief summary of what was in the core, then market will be sceptical hence why the share price may have ended down again.
Conspiracy theory: Nothing noticeable in the core from hole 7 = leaky ship, those in the know selling out ?
