About Sulliden Gold Corporation Ltd.

Sulliden is a mineral exploration and development company focused on advancing its flagship Shahuindo project to production. Currently in its permitting phase, this low-cost heap leach gold and silver project is located in a prolific gold-producing district in northern Peru and has recently received its EIA (environmental permit) approval. A September 2012 Feasibility Study (based on $1,415 Gold and $27 Silver) on the foundation phase of the project estimates an initial CAPEX of $131.8 million that will support an annual mining rate of 3.65 million tonnes producing approximately 90,000 of gold equivalent ounces for 10.4 years at cash operating costs of $552/oz. This initial mine scenario features a pre-tax IRR of 52.2% and post-tax IRR of 37.8%. The technical study considers only approximately 40% of the defined measured and indicated gold oxide mineral resource. Additional mineral resource growth is anticipated from a number of highly prospective exploration targets on the property that remain largely unexplored. Sulliden is led by a proven management team with hands-on experience developing and operating mines in Latin America.
