There is, as always, Silver Bull aka SVB.TO which has a great little deposit they never seem to do anything with. It's already a triple from the bottom but might get a lot more action if the zinc bull holds.
Heather dale Resources -- HTR.V -- has a polymetallic deposit in Alaska that is actually more copper than zinc but they seem to be getting caught up in the bull too.
FV.V has a bunch of zinc deposits in (gulp) Guatemala.
Scozinc aka SZM.V has a nice little zinc/lead deposit in Nova Scotia but I don't like management at all. They tried to sell the property for a pittance a few years ago but fortunately the sale didn't go through.
And of course IVN.TO has an amazing high grade zinc deposit in (double gulp) Democratic Republic of Congo.
