151 years or 300 to 400 years processing with the existing capacity is not worth much when using a discounted cash flow to value a stock. Basically, only profits over the next 10 years when evaluated to present value with a discounted cash flow count. Profits more than 10 years out do not have significant present value. Mining and processing capacity should be designed to work out the deposit in 20 years or less.

ECU needs to build the new mill additions to get production and profits up within 3 years.

The ECU value is determined by planned near term (less than 10 years) production/profits or the value in a buy-out is determined by the buyers expectations of new mining and processing capacity the new buyer would plan to install.
