the ELM deposit is certainly economically viable since it has $80/t opex verses $350+/t potash price, more like $400/t if sold to Brazil

$350/t revenue minus $80/t opex = economically viable = $291M cash per annum or 6.3 year pay back for a mine that has decades of mine life

$400/t revenue minus $80/t opex = economically viable = $375M cash per annum or 5 year pay back for a mine that has decades of mine life

thus the project is not uneconomic

to issue with the project is whether anyone wants to step up & funded it, due to a well-supplied potash market
