My prediction is this
1 100% sure that no other company will make an offer unless they already have operations in Argentina
2 100% sure that Barrick will not make an offer (a lot too small)
3 99% sure that Goldcorp will not make an offer (a bit too small)
4 only companies with $800m is available short term cash can make an offer (buyout plus capex)
5 The list of companies meeting #4 requirement is very short.
Prediction; no new offer BUT if there is no premium as compared to buying YRI shares then you get a sort of free lottery ticket. Keep in mind money will be tied up for 3 months
