RE:$1.70 zincI don 't think the hedging program is specifically tied to Caribou even though it is presented that way. They have hedged 74 million lbs for 2022 - to the extent that Caribou falls short of this the hedging will leach into the African production (yet another downside of disposing of Santander too early). I think a conservative estimate of Caribou production for 2022 would be 50 million lbs which would leave 24 million pounds of hedged production that the African mines would have to cover.
