US miners ask Supreme Court to end uranium mining ban near Grand Canyon
The National Mining Association (NMA) and the American Exploration and Mining Association (AEMA) have filed petitions asking the court to reverse the 2012 ban.
Talon said the submittal covers several key aspects of the Tamarack nickel project, including no crushing or processing of ore at the mine site and water treatment.
Minto Metals' mining site was inspected on April 26, finding that its storage capacity for contaminated water in an open pit and tailings waste management were unsatisfactory.
