Gogebic Taconite has reduced the number of holes it plans to drill, as it researches a possible mine in Ashland and Iron counties.
The state Department of Natural Resources says the company withdrew a request to drill 13 holes to retrieve iron ore samples at the site. A replacement application calls for eight exploratory borings instead.
Gogebic Taconite said it removed five of the original test holes so it could gather information about addressing storm water concerns.
The state will now review the new application before deciding on whether to grant an exploratory permit. The company could apply to drill additional holes at a later date.
