Conceptual Question:
If a mining company has $2bill of profits in the ground, extracted over a mine life of 8yrs, the owners of the mining company should be paid $250mill each year (minus executive bonuses and further exploration costs etc.) in dividends.

So hypothetically If ESS (or CXO) has $2Bill profits in the ground with ~250mill shares on offer, each share should be getting a ~$1 dividend each year. So if you're chasing a 40% return on investment, each share should be worth $5.70 ($5.70*1.4=$8) in the first year of production, assuming there's no dilution of shares over the 8yr mine life.

What am I missing????
