It's a Lawrence Roulston update. He sends out updates on the companies he covers. You must be a member of his letter.
1st time an analyst makes mention of the 4 year clause...he also says it would be impossible to accomplish and my favorite part in the end...control of the clause....
In other words..Teck is &?%$
If Teck does not back in, then Cop-per Fox will continue to control a very large deposit and a district-scale exploration trend. If the major does back in, Copper Fox will be in a strong position, with its partner funding a great deal of work, with control of important ground outside of the joint venture and the four-year development time limit.
