If SFMI does produce larger than the Comstock Mines, here is what the Comstock produced:

United States Geologic Service lists 22 Comstock epithermal vein type mines in the US from 1845-2009, with the Comstock Mines the largest.

Au-Ag ore went to about 2,000', but the deepest mine went to 3,300'.

The mines produced approx. 8.6 mil. oz Au worth today about $11.2 Bil.

The mines produced about 192 mil. oz Ag worth today about $4.2 bil.

The average grade of Au was 14 grams/ton and of Ag was 10 oz./ton.

The main fault system was 8 miles long, with three miles of bonanza ore on strike.

Total value of Au-Ag production from the Comstock mines in today $ is $15.4 bil.

The 1800's average Comstock cost of production was $22./ton, when 1 oz. Au sold for $20. Just like War Eagle Mt., miners only made money if they mined 2 oz. Au equiv. or more/ton.

The average /ton $ value of ore from the Comstock mines was $44., which in the 1860-93 period represented 2.2 oz./ton.

The average Comstock mines Au to Ag ratio was 1:22, whereas WEM is reported to be 1:14.

I would be pleased to think we could produce more than the Comstock mines, with a record like this.
