caribouit sounds likes the new tech. would have the benefit of
1. improving zinc recovery --75-80% recovery could go to much higher say 90-95%.
2. get gold copper silver and lead up. no gold and copper now.
3. get rid of treatment charges.
Wonder if it could be done at other operations.
This could be a huge deal to lower costs.
Plenty of excess milling capacity at Caribou to do satellite deposits.
