2Introduction
This digital movie was created in Microsoft
PowerPoint 2000 to visually describe historical
factors that have influenced patterns of Nevada
mining including, transportation routes, major
historical events, significant mineral deposits,
mining districts, mineral production, and
precious metal booms. The movie includes shorter
animated subsets that the viewer can select from
a set of menu buttons.
3Mining Activity in Nevada, 1851 - 1995
Precious metal mines and mining camps dominated
Nevadas early history until WWI. Base metal
surpassed precious metal production during the
war and post-war years to the early 1960s. Due
to new technologies and high gold prices,
precious metal production reached new highs
during early 1990s.
4Patterns of Nevada Mineral Activity
Mining Activity in Nevada, 1851 - 1995
Low prices and environmental regulation brought
about the decline in precious metal production by
1995. More recently Nevadas fast growing
population and urban infrastructure has created
an increasing demand for industrial minerals.
Nevadas three major boom periods were known as
the Comstock, the Tonopah-Goldfield, and the
Carlin.
5Patterns of Nevada Mineral Activity
Mining Activity in Nevada, 1851 - 1995
This digital movie depicts the significant
activity cycles in Nevada during the period 1851
1995 for Precious metals (silver and gold)
Base metals (copper, lead, zinc and tungsten)
Industrial minerals (such as sand, clay, gypsum
and barite) The relationships between
transportation routes, mineral exploration and
production, active mining districts, and
population growth or decline are shown by decade.

78Mining Activity in Nevada, 1851 - 1995
- SUMMARY
- The 1859 silver discovery near Virginia City
began the Comstock Boom. - Most of Nevadas mining districts were
discovered during the Comstock Boom and the
Tonopah-Goldfield Boom aided by the development
of the railroads. - A period of decline from 1892-1899 due to a drop
in silver prices and depletion of mines caused a
population decrease. - WWI stimulated mining by raising the price of
silver and base metals.
79Mining Activity in Nevada, 1851-1995
- SUMMARY
- In 1933 a minor depressionera boom was set off
by an increase in the price of gold contributing
to early discoveries of invisible gold later to
be called Carlin-type deposits. - WWII increased the demand for all metals
however, the War Production Board forced most of
the gold mines to close to stimulate base metal
production. - Base metal production peaked during the 1950s
copper was at its highest. - The 1962 Carlin gold discovery began the Carlin
Boom.
80Mining Activity in Nevada, 1851 - 1995
- SUMMARY
- The demand for base metal remained high and
increased for industrial minerals during the
1970s Vietnam War. - In 1972 the price of gold was released from
government control, and Nevada led the nation in
gold production in the 1980s. - In the 1990s lower prices and environmental
regulation brought a decline in precious metal
production, and by 1992 the changing market
conditions practically eliminated Nevadas base
metal industry.
81Mining Activity in Nevada, 1851 - 1995
- SUMMARY
- The demand for industrial minerals has steadily
increased with Nevadas growing population and
will most likely continue a steady upward trend.
