RE:RE:RE:GSPI think you are partly right Brown. The problem in this industry is that only one group has ever done more than a cursory look at actually look at what is really happening in selective mining, looking carefully at the phase chemistry, relating that to dissolution rates and adapting that knowlege to the ore deposits that are being encountered.
The industry has been dominated by incorrect assumptions about what might happen based on, mostly poor data, or no actual data at all, on existing solution mining applications. That is coupled with the idea that capital requirements for this new selective mining might be still in the range of $1000 a tonne annual capacity. The high prediction of capital cost, with the "uncertainty reguarding operating cost" (with no good data), makes these projects marginal at low potash prices.
In reality the proper sudies should have capital cost at $100 to maybe $300 a tonne and operating cost about $50 a tonne. This rocks. But there is a lot of resistance...I just don't know why.
