9. Asset Retirement Obligations

The Company retained the services of a mining engineering firm to prepare a detailed closure plan for the Velardeña Properties. The plan was completed during the second quarter 2012 and indicated that the Company had an ARO and offsetting ARC of approximately $1.9 million. The estimated $3.5 million ARO and ARC that was recorded at the time of the acquisition of the Velardeña Properties was adjusted accordingly.

The Company will continue to accrue additional estimated ARO amounts based on an asset retirement plan as activities requiring future reclamation and remediation occur. During the first six months of 2014 the Company recognized approximately $0.1 million of accretion expense and approximately $0.1 million of amortization expense related to the ARC.

The following table summarizes activity in the Velardeña Properties ARO:

The decrease in the ARO recorded during the six months ended June 30, 2014 is the result of changes in assumptions related to inflation factors and discount rates used in the determination of future cash flows.

The increase in ARO recorded during the six months ended June 30, 2013 relates to a change in assumption related to inflation factors used in the determination of future cash flows. The corresponding increase in ARO was discounted using the Company’s current credit-adjusted risk-free interest rate.

The ARO set forth on the accompanying Condensed Consolidated Balance Sheets at June 30, 2014 and December 31, 2013 include approximately $0.1 million of reclamation liabilities related to activities at the El Quevar project in Argentina.
