Nevada has been a prolific mining region in the US since the famous Comstock silver discovery in the late 1800s. However, it is now gold that draws miners to Nevada. Gold deposits in Nevada are unique in that they cannot be seen by the naked eye. This makes them difficult to find. Despite this, gold occurs in massive trends that which constitute the second largest concentration of gold on earth after South Africa. In 1962, gold was struck outside the town of Carlin and ever since The Next American Gold Rush began. Nevada currently constitutes 73% of all US gold production and gold makes up 84% of all value of Nevada’s mineral and energy production per year.
