Basic Question for the Board
There are goldmine tailings piles from the 1800's all over the West, and hardly any of them are being reworked, even though grades of well under 1/4 oz/ton would be economical.
That would tell me that the mining techniques of the 1800's were much too sophisticated to leave a pile with the sort of grades SFMI is talking about.
How did this happen?
Hard work often pays off over time,
but laziness always pays off right now.
