Quite a long tme is the answer.
After 90 days suspension, the procedure for relisting becomes more onerous.
Barkerville relisted after a year and a bit, but it was difficult to relist as there are more hoops to jump through, one of which is having a certain percentage of your annuual burn rate in the bank, If I recall correctly.
So, another 40 days to go before relisting would become more difficult, around 7th October.
This may explain the surge of activity of the Lori sycophants on SH, as they are putting in a massive effort to try to discredit people, which makes no sense if the company is "dead"!
