RE:RE:RE:QuestionYes, it's all pretty speculative because getting info from IMG is pretty much impossible on those sorts of questions and it is IMG who would pretty control what happens.
One thing about Karita is that miners typically don't buy untested ground. The typical process is for a small high risk explorer like MXI (no risk now though) to spend enough on testing and drilling to make a discovery then sell it to the highest bidder or do more work on it in a JV. So under conventional practices, MXI or its successor company would hold Karita independently and do some work on it, then sell it once something is proven. That's not a rule so anything can happen here. I would say that if IMG doesn't want to pay a reasonable amount for Karita, then a MXI successor company would keep it and raise funding for it.
Unless IMG was paying cash, it is unlikely they would buy out the JV only. It would be pretty complicated to give MXI shares for it, but that is possible. That would be interesting though: IMG owning 25% of a company whose value is based on it's own IMG shares!
We do know how IMG handled the Orezone purchase when they got Essakane. They bought out Orezone, spun out some unworked properties into a new company, and even provided some capital to get them going. Like with MXI, IMG also held a position in Orezone and of course the new Orezone in the same proportion. So if the past is indicative of how a MXI deal would go, the IMG/Orezone deal is a good one to look at.
This is all pretty speculative, there are probably a few other possible scenarios.
