CODY, Wyo. – The Bureau of Land Management has analyzed a proposed bentonite mining expansion project in Big Horn County, 15 miles southeast of Lovell. The BLM Cody Field Office will accept comments on the environmental assessment through April 12, 2024.

American Colloid Company plans to expand its current mining operations by 109.1 acres, including 50.2 acres of BLM-managed federal land. The proposed expansion would provide an estimated 170,000 tons of bentonite from public lands over the life of the project and would continue to employ approximately 15 mine employees, and 130 mill and contract employees.

America’s multiple-use public lands support countless communities, providing jobs and economic development for millions of Americans.

“Mining projects like these continue to create jobs and serve our local communities, while ensuring the sustainable use of public lands for the benefit of all Americans,” said Cody Field Manager Cade Powell.

Bentonite is a volcanic clay used in dozens of industrial applications, including oil and gas drilling, construction, paints, pharmaceuticals, cosmetics and other consumer products.­

The environmental assessment, as well as the mine and reclamation plans submitted by American Colloid Company, are available for public review by visiting the BLM ePlanning site at https://eplanning.blm.gov/eplanning-ui/project/2031356/510, and in person at the BLM Cody Field Office, 1002 Blackburn Street.

The comment period runs from March 14 through April 12, 2024. Comments may be emailed to blm_wy_cody_wymail@blm.gov; please include "ACC Radar” in the subject line. Comments may also be mailed to AFM Minerals and Lands, BLM-Cody Field Office, 1002 Blackburn Street, Cody, WY, 82414.
