RE:Has anyone seen Gsp's latest Technical Report?BPPC started promoting the polythermal, selective solution mining in 2009. The contention was that a small 250,000 tpa mine should easily be built using this new technology for well under $100,000,000. Depending a little on the availability of utilities, roads and rail, and the desire for a luxury office building, this could be done for $30,000,000. This would provide a basic starter mine with a 6 month payback.
