The
figures in this table are also those of the Director of the Mint. They
result from cooperation of the Bureau of the Mint and the United States
Geological Survey and are agreed upon after conference and adjustment
between the two bureaus. They are, therefore, final for both.
The
totals of this table are based on bullion deposits in the United States
mints and assay offices and on returns to the Bureau of the Mint from
the smelting and refining companies. The distribution is adjusted by
information collected by the United States Geological Survey direct
from the producing mines and tabulated for the mine reports later
discussed. The data giving the total production, and in part the
distribution, are obtained from records of (1) the unrefined domestic
gold and silver deposited in United States mints and assay offices, (2)
the domestic gold and silver in fine bars reported by private
refineries, and (3) the unrefined domestic gold and silver contained
in ores, matte, etc., exported for reduction. The last item is of small
relative importance.
Gains
and losses in the production of gold and silver in the several States
and Territories, as compared with the output of 1911, are shown in the
following table:
