MY TWO CENTS WORTH...Historically, RIO negotiates an 18 month contract/working agreement with WRN. About 12 months pass and RIO makes a low offer to buy WRN thinking they will "steal" it. Dale/WRN rejects the offer and announces a surprise extensive drilling campaign that just so happens to continue up to and maybe beyond the 18 month agreement with RIO.
If I put myself in RIO's shoes, I would quickly get back to the bargaining table because if the drill results are promising, the FS results will be heightened, the price increases dramatically, and the market will be open for a bidding war that none of us can even predict at this point in time!
If RIO is smart, they will never let things go this far and will make an offer that WRN is totally comfort with because RIO needs this mine in a safe environment given their difficulties in other countries of late.
We, as shareholders, will far much better if the bidding war occurs. But, either way we will be rewarded very nicely! Stay the course, the future is bright!!
