Net income of the Company before deferred taxes for the fourth fiscal quarter ended September 30, 2012 was US $449,000 compared to US $400,000 in the comparable quarter a year ago.

On a stand alone basis, the Pimenton mine had net earnings for the fiscal year ended 2012 of US $2,735,000 before deferred tax of US $881,000 compared to net earnings of US $6,797,000 a year ago. During the first fiscal quarter of 2012 the Pimenton mine was adversely impacted by a crown gear failure on the ball mill which substantially reduced gold, copper and silver production during the quarter.

The Company will receive new mining equipment during the first calendar quarter of 2013 which is expected to increase its rate of mine development and reduce the mines' maintenance and repair costs.

Cash cost per ounce of gold sold at the Pimenton mine, net of by product credits, was US $1,156.50 in fiscal 2012 compared to US $716.65 per ounce in fiscal 2011.

Stephen W. Houghton, CEO stated that the Company is working to reduce expenses at the Pimenton mine and to further increase production from its current level of 120 tons per day which should reduce its cash cost per ounce. The Company was able to significantly increase its exploration costs during its fiscal year ended 2012 while maintaining a strong balance sheet, which many small junior mining companies have been unable to accomplish in recent times.

Cerro Grande Mining Corporation is a minerals producing, exploration and development company with properties and activities currently focused in Chile.
