Agree that bolt-on assets with long life and quality grades are sought-after and increasingly rare commodities. However, at this point in time AVB has got just one small mine in production and its other assets may be insufficiently advanced and de-risked to result in a generous counter offer.
As a result, it may not be unreasonable to take up the offer and buy more OZL with the cash component. In that way retaining skin in the Carajas game and a solid investment.
