 The value of metal production herein reported for Colorado, New Mexico,
Texas, South Dakota, and Wyoming has been calculated at the figures given
in the table that follows. Gold is figured at the mint value for fine gold;
that is, $20.671835 an ounce. The silver price is the average New York price
for bar silver. The copper, lead, and zinc prices are weighted averages,
for each year, of all grades of primary metal sold by producers.
