"If BHP believes all is right, they don't need to be putting that on the Navajo people," she said. "That certainly needs to be taken away, and we don't even know what those liabilities are."Moyer said the due diligence studies were not released publicly because of confidential business information contained within them. Redacted portions could be released once the mine is in the hands of NTEC, he said. The studies found no significant external impacts from the mine, he said, and the Navajo Nation will not be saddled with unexpected costs. The Navajo Nation will acquire mining equipment, improvements at the mine, intellectual property rights and permits. Ten percent of the profits from the mine will be set aside for clean energy development. Pat Risner of BHP released a statement Thursday saying the company was pleased to work with the Navajo Nation to ensure a future for the mine that will benefit the tribe, mine employees and others.
