"So, Kinross in Mexico (KGEM) randomly contacted Southridge because it has no assets in Mexico?"
I suspect one of SRGE crooks contacted a Kinross employee and said they wanted to talk. In order to do that, a CDA would have been exchanged - that's normal practise.
The SRGE used the CDA to pretend a JV had been created, but KInross spotted the lie before too much damage was done.
Simple.
