AngloGold Ashanti plans more exploratory borings in Northland

AngloGold Ashanti submitted plans to the Minnesota Department of Natural Resources for more exploratory borings in its search for gold.

The South African-based company proposed 26 drill sites in northeastern Itasca County.

The company plans to use existing access roads and conduct "rotosonic" drilling involving high-frequency vibration of the drill bit to collect core samples of soil, glacial sediment and some bedrock.

Drilling would occur this fall and winter but pause for deer hunting season.

AngloGold Ashanti is based in Johannesburg and has a North American office in Centennial, Colo. It is the third-largest gold mining company in the world with 14 operating mines in 10 countries, according to the company's website. The company also has several exploration programs in both established and new gold-producing areas.
