Gold in Nevada: The Real Golden State
The Real Golden State: Gold Production in Nevada
Thanks to the world famous silver discoveries of the 19th century that
unveiled Nevada’s precious metal potential, the state today is known by
many as “The Silver State”.
However, it’s possible that nickname may need to be updated. In the last
few decades, Nevada has become a prolific gold producer, accounting for
84% of total U.S. gold production each year.
Today’s infographic from Corvus Gold showcases
why Nevada may have a better case for deserving California’s nickname
of the “Golden State”: we look at the state’s gold production,
exploration potential, and even its rich history.
A Defining Era for the American West
The discovery of the Comstock silver lode in
1859 sparked a silver rush of prospectors to Nevada, scrambling to
stake their claims. News of the discovery spread quickly throughout the
United States, drawing thousands into Nevada for one of the largest
rushes since the California Gold Rush in 1849. Mining camps soon thrived
and eventually became towns, a catalyst that helped turn the territory
into an official state by 1864.
Interestingly, many of the early mines also produced considerable
quantities of gold, indicating there was more to the state than just
silver.
- The Comstock Lode: 8,600,000 troy ounces (270t) of gold until 1959
- The Eureka district: 1,200,000 troy ounces (37t) of gold
- The Robinson copper mine: 2,700,000 troy ounces (84t) of gold
The Comstock Lode is notable not just for the immense fortunes it
generated but also the large role those fortunes had in the growth of
Nevada and San Francisco.
In fact, there was so much gold and silver flowing into San Francisco, the U.S. Mint opened
a branch in the city to safely store it all. Within the first year of
its operation, the San Francisco Mint turned $4 million of gold bullion
into coins for circulation.
While California gold rushes became history, Nevada mining was just
beginning and would spur the development of modern industry. In 2018,
California produced 140,000 troy ounces of gold, just a fraction of the 5.58 million oz coming out of Nevada’s ground.
Nevada Gold Mining Geology: Following the Trends
There are three key geological trends from where the majority of Nevada’s gold comes from.
- Cortez Trend
- Carlin Trend
- Walker Lane Trend
Together these trends contributed nearly 170 million ounces of gold
produced in Nevada between 1835 and 2018, making it the United States’
most productive gold jurisdiction, if not the world’s.
The bulk of production comes from the Cortez and Carlin Trends, where
mines extract low grade gold from a particular type of mineral deposit,
the Carlin Type Gold deposit.
It was the discovery and technology used for processing these
“invisible” deposits that would turn Nevada into the golden powerhouse
of production.
Today, the world’s largest gold mining complex, Nevada Gold Mines,
is located on the Carlin Trend. The joint venture between Barrick and
Newmont comprises eight mines, along with their infrastructure and
processing facilities.
Despite the prolific production of modern mines in the state, more
discoveries will be needed to feed this production pipeline—and
discoveries are on the decline in Nevada.
Looking to the Future Through the Past: The Walker
Lane Trend
The future for gold mining in Nevada may lie in the Walker Lane Trend. This trend is host to some of the most recent gold discoveries, and has attracted the interest of major mining companies looking to conduct exploration, and eventually, production.
Walker Lane stands out with exceptional high-grades, growing reserves,
and massive discovery potential. It also played an integral role in the
history of the state beginning with the 1859 discovery of the Comstock
Lode, and it seems likely to continue doing so in the future.
