Minerals Industry Report for Rhode Island

In 2007, Rhode Island’s nonfuel raw mineral production was valued at $52.3 million, based upon annual U.S. Geological Survey data. This was an $5 million, or 11%, increase from the State’s total nonfuel mineral value for 2006, which was then up by $11.7 million, or more than 33%, from 2005 to 2006. Because data for industrial sand and gravel and crushed limestone (2005) have been withheld (company proprietary data), the State’s actual total nonfuel mineral values for 2005–07 are higher than those reported in table 1.

Most of Rhode Island’s nonfuel mineral production resulted from the mining and production of two basic construction materials—construction sand and gravel and crushed stone. In 2007, these two mineral commodities accounted for nearly 60% and more than 40%, respectively, of the State’s nonfuel raw mineral economy that may be publicly disclosed. Data for crushed granite and miscellaneous stone are subdivided in table 2. 
In 2007, despite a small decrease in production, construction sand and gravel led the State’s increase in value with a $5.4 million, or 21%, increase in production value. Although the production of crushed stone decreased by 13%, its production value decreased only slightly. Small decreases took place in the production and the production value of industrial sand and gravel. Gemstones, the value of which was estimated, continued to be mined in the State by hobbyists only.
