Desert Hawk Gold Corp (DHGC) is a fully permitted and operating open pit / heap leach gold mine in western Utah.

DHGC has a land package of approximately 1,500 acres of both patented and unpatented claims near Gold Hill, UT. The project is located in western Tooele County in the Clifton Hills on land which include public lands administered by the BLM, Salt Lake Field Office; Utah School and Institutional Trust Lands Administration (SITLA); and private lands leased to Desert Hawk.

The project is located in the historic Clifton-Gold Hill Mining District, known for deposits of gold, silver, copper, lead, zinc, arsenic, and tungsten. The company is currently mining and processing gold ore, while conducting exploration projects throughout the district.

Desert Hawk submitted to the BLM Salt Lake Field Office (SLFO) a Notice of Intention (NOI) to Commence Large Mining Operations for the Kiewit Project.

Responses from the NOI prompted the BLM to require a full Environmental Assessment.

    • Biological Environment (vegetation, invasive species and noxious weeds, migratory birds, wildlife resources)
    • Socio-Cultural Environment (Cultural, socioeconomics, lands/access. Livestock grazing, recreation, native American religious concerns, environmental justice)
