Snapshot	The Mill Creek operation consists of the Mill Creek mine and two silica sand processing plants separated by four miles. Production data has not been available.

Deposit type

• Sedimentary
• Sandstone hosted

Summary:

The deposit has a minimum silica (SiO2) content of 99%. The controlling attributes are iron (Fe2O3) content, calcium (CaO) content and grain size distribution. The sand/overburden contact is occasionally concentrated in calcium and any sand with greater than 0.03% CaO is removed during the overburden removal process. Sand with iron greater than 0.03% Fe2O3 is not mined.

The reserves are part of the Oil Creek Formation in south-central Oklahoma.
