RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:TREVALI EXTENDS ZINC HEDGING PROGRAM OUT TO END OF 2021Actually, if you look at their corporate presentation from Q4 2019, you will see that AISC was 1.24 in Q4 but was 1.05 in Q3 of that year. It only went up when they had the technical issues and had lower throughput to the mine due to it. They have since corrected those issues and with other cost reductions, lower TCs and increases in both zinc and silver prices.....$1.25 would be too high if/when they reopen the mine. I think your re-opening cost are a bit high but considering they are already paying for maintenance, opening it might not be as bad as you think
