Answer:
A: silver
Step-by-step explanation:
Among various mineral resources mined in Nevada, Silver is one of the resources: known as a "precious metal" due to its scarce and high economic value.
While all the silver produced in Utah is derived from the Bingham Canyon Mine, which produces silver as a byproduct of copper mining.
In Nevada silver is mined as a byproduct of the mining of gold.
In recent years, it has been documented that Nevada produced 9.5 million ounces of silver.
Among many other properties, silver has an attractive color and luster that resist tarnish and make the metal desirable in jewelry, coins, tableware, and many other objects.
Silver usage is often required when performance is more important than price.
