Hi YT, yes I am aware of their potash ground and it's potential but it's not a commodity I know a lot about.I'm spending this weekend trying to get up to speed a bit on it.I am particularly interested as to what type of ground is prospective for it as I am trying to find about "hard rock" sources as opposed to the brine lakes(playa lakes) sources.
Actually I hold a number of companies whose ground I am wondering whether it may hold potential.I know phosphate is often located on ground which is also prospective for uranium so I will be having a closer look at a few of my holds in the Cloncurry area as well as a company I hold in Botswana which I know has playa lakes on it's leases.West Australia has a multitude of playa lakes also so I am looking at who holds ground around them and which may be prospective for potash or potassium sulphates
