Asset Retirement Obligations, Description In 2016 management estimated the initial cost to reclaim the Golden Chest mine to be $42,182. During the year ended December 31, 2017, the obligations for the Golden Chest and New Jersey mill properties were revised in consideration of additional disturbance activity and timing of future reclamation. The estimated reclamation costs were discounted using credit adjusted, risk-free interest rate of 5.0% from the time the obligation was incurred to the time management expects to pay the retirement obligation.
