Although gold production increased significantly, the overall value of commodities mined in California fell in 2010, according to a new California Geological Survey report.
At $2.9 billion, California ranked sixth in the nation for value of non- fuel mineral production.
The Golden State trailed Alaska, Minnesota, Utah, Arizona and Nevada, respectively, in 2010.
California accounted for 4.2 percent of the nation's mineral production. In 2009, the state ranked fourth, accounting for about 6.3 percent of the national total.
"The lion's share of mining in California is for construction-grade sand and gravel, and with the recessionary downturn in construction in the state, it's no surprise that production showed a significant decrease," said John Parrish, California's state geologist and head of CGS.
In 2010, CGS said construction-grade sand and gravel had an estimated value of $809 million for 82 million tons produced in-state.
California produced more than two dozen industrial minerals in 2010, leading the nation in diatomite and natural sodium sulfate production.
