DS: Well unless the cash costs have trebled since the September 9th 2014 in-house definitive mining plan, based on the January 15th 2014 Tetratech PEA ($947/t) then there is no reason to suspect it is sub-economic at $2,800/oz.
According to the CSO.ie (Irish Central Statistics Office) CPI calculator $947 in September 2014 is $1,153 today, albeit exchange rates, internationally procured mining equipment, energy and salaries may deviate from that.
The only way the grade might go down on the existing resource is if the cut-off is increased. That is why the 1Moz went down to 0.52Moz (0.75g/t in 2008 to 1g/t in 2017). In fact at higher prices, cut-off grade is normally dropped, and anyway mining grade invariably exceeds predicted grade because exploration results by necessity are based on an incomplete picture.
But again, all you have to offer is your "opinion" rather than any research based on demonstrable numbers, and I suspect you know little about what you are talking of - you've just picked up on some buzzwords like "refractory" and "biox" which just means the gold is more tightly bound up in minerals like sulphides which are most easily broken down by bacteria rather than chemically, by heat or physically, rather than in oxides or as free gold.
