something doesn't add up, page-6

Is the lower quality with thinner beds at the edge a common thing with these deposits at other places or is it perculiar to this deposit??. I'll interrogate a geo friend of a friend on the weekend who doesn't know a lot about potash but will be able to find out. I want to hit him up with some decent questions on this one.

So is the lower grades related to thinner beds , or the way thinner beds are formed, movement of concentration within the bed? or just teh way it is in these sorts of deposits.

Havent decided if it was tree shaking or a leaky ship aware of the downside and placing dollars in the rest of teh market moving in teh other direction? It is eaither leaky or someone is guessing right several times or pushing stops about?

Thanks
