Shorters don't know any more or any less than we do. Perhaps they are looking at the balance sheet and figuring that RVX will go to pot, with the SPP hovering in the $0.50 mark and all and with little to no cash in the back. But if RVXCF short count is correct of ~600K and the RVX.TO is now at ~400K, which totals to 1M being shorted with 22 "Days to Cover" short positions to boot, 22 days can be a long time to cover their bets without the SPP spiralling out of control, should a bit of good news springs up overnight. 

The optimist in me is betting that the Nov 3, 2021, Globe Newswire has teeth.
