As Mal indicates, clearly 80Ktpa is some time away however we should not lose sight of fact that even say 28Ktpa (112t per day for 250 work days) @ 20g/t gives us 18,000 oz gold.
At $AUD1400 that is $22.6m income Say $600/oz cost = ($10.8m) Leaves ~$11.8m NP 251m shares issued -> 4.7cps Use P/E 25 -> $1.18 implied share price
So even to get a couple of stopes producing at that sort of rate should see a major change in sentiment. Let alone to factor in further upside (which P/E of 25 only does to an extent).
