Montana Resources does not need a permit to remove copper from the Berkeley Pit water, according to a state official.
John Tubbs, director of the Department of Natural Resources and Conservation, told The Montana Standard Monday that after reviewing MR’s planned pilot project to begin pumping and treating Berkeley Pit water late this year or early next year, the agency has determined that the mining company does not need a permit to remove the copper.
The Butte mining company expects to recover around 100,000 pounds of copper a month from the pit water when the project begins. With today’s price of copper, which is $3.11 a pound, that would mean MR would gain approximately $311,000 a month from the extraction process should the price of copper remain at that level by next year.
