The Palmarejo mine is an underground and open pit silver and gold mine located in the State of Chihuahua in northern Mexico, and the company controls a large portion of the properties surrounding the mine. The Palmarejo mine commenced production in April 2009. The San Bartolomé mine is a silver mine located near the city of Potosi, Bolivia. The mineral rights for the San Bartolomé project are held through long-term joint venture/lease agreements with several local independent mining co-operatives and the Bolivian state owned mining organization, (“COMIBOL”). The Company commenced commercial production at San Bartolomé in June 2008. The Kensington mine is an underground gold mine and consists of the Kensington and adjacent Jualin properties located north-northwest of Juneau, Alaska. The Company commenced commercial production in July 2010. The Company has conducted operations at the Rochester silver and gold mine, located in northwestern Nevada, since September 1986. The mine utilizes the heap-leaching process to extract both silver and gold from ore mined using open pit methods. The La Preciosa silver and gold project is located in the State of Durango in northern Mexico. The Company completed a feasibility study in 2014 and has deferred construction activities until expected returns improve. The Joaquin silver and gold project is located in the Santa Cruz province of southern Argentina. The Company commenced exploration of the property located north of the Company's Martha silver mine in November 2007.

Limited, a wholly-owned subsidiary of CBH Resources Ltd. The Company has received 5.4 million payable ounces to-date and the current ore reserve contains 1.7 million payable ounces.
