It’s a gold rush in northern Minnesota – by John Myers (Grand Forks Herald – November 10, 2016)

COOK, Minn.—AngloGold Ashanti continues to move quickly in its efforts to find mineable gold in Koochiching County in far northeast Minnesota. The Minnesota Department of Natural Resources reports this week that AngloGold has submitted a plan to do exploration drilling on state-owned mineral leases about 20 miles west of Cook.

State mineral rights that are leased often sit for years, even decades with little or no action. But AngloGold is moving fast, first obtaining mineral rights from the state in March and then announcing in June it was ready to start a focused search for gold with basic tools. This is the first actual drilling at the site.

The DNR says AngloGold plans to drill 31 exploratory rotosonic borings within 19 active state nonferrous metallic minerals leases using “rotosonic drilling” — a high-frequency vibration of the drill bit to collect cores of unconsolidated glacial sediment and underlying bedrock.

The company reported to the DNR that no drilling fluids are needed. It should take less than a few days to complete each boring down to about 150 feet below the surface.

The company’s geologists will then examine the core samples removed from each hole to check for gold in an effort to hone in on a gold deposit where traces of gold already have been found.
