What has to be realised here is that the delay is for a very good reason. The recent metallurgical test work has determined that a very substantial increase in recoveries can be gained by a finer grind. Previous recoveries were very low. Increased recoveries mean substantially increased profit on each ton processed and will be very valuable in the medium term.
The finer grind requires modifications to the existing new plant before it is fired up. This is concerning in the short term but will mean considerable increased profit in the medium term. We are seeing the short-term bias of the stock market. Next calendar year, all will be well.
