Gogebic starts test drilling
Exploratory drilling into the largest deposit of iron ore in North America could begin as soon as Saturday in northern Wisconsin’s Penokee Range.
According to the Duluth News Tribune, Gogebic Taconite filed a notice of intent to drill with the Department of Natural Resources in a letter dated Friday. Department of Natural Resources waste management director Ann Coakley said GTAC can start drilling five days after they get the notice, and they received the notice Monday.
Eight holes, one in Ashland County and seven in Iron County, will be drilled this month. Coakley said the DNR will keep an eye on the operation with unannounced spot-checks.
The bore holes will be 350 to 1,143 feet deep. The 2-inch holes will gather data on the layers of rock, the quality of the iron ore and the chemicals in the ore body.
