Drilling on the last exploration site in eastern Oneida County was completed on Wednesday.
Badger Minerals had been overseeing the drilling program, which sought to gather data about potential sulfide minerals hundreds of feet under the earth.
Drilling started on June 5.
Drill cores will be taken offsite and reviewed by geologists, and some will be submitted for lab analysis.
It was the first mining-related drilling program in Wisconsin in eight years, and the first in Oneida County since at least the 1980s.
Badger Minerals is now in charge of abandoning the drill holes and reclaiming the land.
There’s no indication yet on if the company might take further mining-related steps.
