World Resources: An assessment of U.S. gold resources indicated
33,000 tons of gold in identified (15,000 tons)
and undiscovered (18,000 tons) resources.8
Nearly one-quarter of the gold in undiscovered resources was estimated
to be contained in porphyry copper deposits. The gold resources in the
United States, however, are only a small
portion of global gold resources. |

World silver mine
production increased to a new record of 24,000 tons as a result of increased
production from mines |
in China,
Kazakhstan, and Mexico, as well as increased recoveries from mines in
Indonesia and Peru. Production |
also increased in
Australia because of the start up of the Wonawinta Mine (lead-zinc) in New
South Wales and a |
major expansion for
the Mount Isa (copper-lead-zinc), which was processing ore from the newly
opened Lady Loretta |
Mine (copper) in
Queensland. In 2012, the Sindesar Khurd Mine (lead-zinc) in India was
estimated to have produced |
70 tons more of
silver than it produced in 2011. Overall, domestic silver production
declined, with the temporary |
closure of Lucky
Friday Mine, ID, in January 2012, the leading domestic primary silver mine in
2011. The mine was |
ordered closed by
the Mine Safety and Health Administration after an accident and rock burst at
yearend 2011 that |
led to a buildup of
material in the Silver Shaft, the primary access to Lucky Friday. Production
was expected to |
resume in early
2013. Output also fell at Bingham Canyon Mine, UT (copper-molybdenum), at the
Mission Complex, |
AZ
(copper-molybdenum), and at the Midas Mine, NV (gold). Some of the output
losses were partially offset by |
production gains at
the Rochester Mine (primary silver) and at the Smoky Valley Common Operations
(gold), both in |
Nevada. |
