RE:RE:I think it's a good sign that...
Hate to be a downer but I'm pretty sure that this is a catch up SEDAR filing. I recall that with one of the PP's in 2023, I noticed that there was a missing insider filing for RDW. The details also match as far as price 0.22 per share plus 0.28 warrants. I'd have to go back and find which one it was but I suspect that this is TLT realizing that one of many SEDAR filings was missed and playing catch up.
I don't think there is a mechanism for RDW to buy shares like that outside of an offering or on the open exchange.
