RE:Imbarassing volume. Me too. Part of the answer may be that the last two PP's were on the AIM market in London. TXP trades there, some days hardly at all and some days a lot.

It traded 843,000 shares today, closing at 14 pence or C$0.24. Apparently it isn't worth any market maker's while to arb between the two markets.
Also, no recent operational or financial update.
Meanwhile there is 160 shares traded today on TSX today at C$0.26. I hope the kid who invested that $40 from his paper route does very well out of it.
