I think there are too many differences in this deposit. The 2 biggest points would be that Argentina is not as friendly a mining jurisdiiction at the moment and that the litigation with TNR could be a huge drag for this deposit. The heavyweights invested in TNR will not go away quietly. It just points out how important Schaft Creek is with location and legal standing.

As an aside, here is an article showing the difficulties big miners face in increasing their reserves.

'Big miners need new deposits to offset falling output at mines that were discovered in the previous boom of late 1970s and early 1980s. But these companies have tended in recent years to leave exploration largely to small companies, known as “juniors”, which are now struggling to raise equity funding to drill.'
