## Introduction 

- 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.

## Mining Activity in Nevada, 1851 - 1995 

- Precious metal mines and mining camps dominated Nevada’s early history until WWI.  Base metal surpassed precious metal production during the war and post-war years to the early 1960’s.  Due to new technologies and high gold prices, precious metal production reached new highs during early 1990’s.

## Patterns 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 Nevada’s fast growing population and urban infrastructure has created an increasing demand for industrial minerals.  Nevada’s three major boom periods were known as: the Comstock, the Tonopah-Goldfield, and the Carlin.

## Patterns 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.

## Mining Activity in Nevada, 1851 - 1995 

- SUMMARY
-  The 1859 silver discovery near Virginia City began the Comstock Boom.
-  Most of Nevada’s 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.

## Mining Activity in Nevada, 1851-1995 

- SUMMARY
-  In 1933 a minor “depression”era 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 1950’s – copper was at its highest.
-  The 1962 Carlin gold discovery began “the Carlin Boom”.

## Mining Activity in Nevada, 1851 - 1995 

- SUMMARY
-  The demand for base metal remained high and increased for industrial minerals during the 1970’s Vietnam War.
-  In 1972 the price of gold was released from government control, and Nevada led the nation in gold production in the 1980’s.
-  In the 1990’s lower prices and environmental regulation brought a decline in precious metal production, and by 1992 the changing market conditions practically eliminated Nevada’s base metal industry.

## Mining Activity in Nevada, 1851 - 1995 

- SUMMARY
-   The demand for industrial minerals has steadily increased with Nevada’s growing population and will most likely continue a steady upward trend.
