I personally think that platinum in the ground, with no plant to pull it out, is very difficult to evaluate. The risks involved for greenfield operations are way, way too high. First you have to do your BFS - (hopefully this is done already?), that takes about 1 year, I think. Then you have to strip mine the surface, then you have to build the plant. The value of the mineral rights is cool, if you intend selling them, but if you intend pulling it out hte ground and processing it, then the value is more related to the ROCE, so then a whole lot of factors come into play e.g. 1) how quickly they can bring the plant up to speed, 2) how accurate the BFS is 3)what kind of mine management skills do they employ 4) will they be sufficiently capitalized (has anyone ever found a startup that was adequately capitalized from the word go?) 5) will they hit production targets 6) will they keep their costs in check, etc. Look at the problems Platmin is facing, and they have some of the best brains in the business driving them
