RE:Intriguing Perkoa update I have mentioned this before as the mining and rehab won't have to be st deepest levels as that is where they are extending the t3 decline for additional drilling stopes and easier cheaper drilling.
it is possible and would have been smart to do j fill drilling to prove up the additional indicated and inferred to extend mine life as well as find immediately adjacent additional ore. 3 remains years mine life would be good as would allow and help fund t3 preparation or at least allow for better priced sale.
it wouldn't surprise me if tfe don't implement the new mining technology at Perkoa either to lower cost structure for beyond 1 year and on t3
