From memory the company is predicting around 100K oz per year for the next 3 years , mainly from higher grade ore going through the plant , LJs predicted prodn for the last FY was on target) given it is making money on 80K oz per year the difference between 80k oz and 100k oz being 20,000 oz should be like making money for jam , doubt the other companies mentioned will be able to turbo charge their operations in the same way with negligible rises in expenses .
Say $1600 * 3 years * 20,000 = $96M * 60% after royalties and tax =$ 57M ...................... if it is not squandered that is some serious extra cash to decrease the EV
