The Company has, pursuant to its news release dated January 28, 2013 (the “January 2013 News Release”), announced that it entered into an agreement with Oroco Resource Corp. to acquire Oroco’s Cerro Prieto Project. The Company wishes to clarify that this transaction has not yet completed and its completion is subject to approval of the shareholders of Oroco and the TSX Venture Exchange as well as standard closing conditions. The January 2013 News Release and the Company’s Corporate Presentation “An Emerging Gold Producer in Mexico, Corporate Update – February 2013” made reference to a “current resource” at the Cerro Prieto Project. The Company wishes to clarify that the resource estimate is historical in nature, as it was not prepared by or on behalf of the Company, and is based on a technical report titled “Preliminary Economic Assessment Technical Report on the Cerro Prieto Project Magdelena de Kino Area, Sonora State Mexico” dated January 28, 2011 on the Cerro Prieto Project prepared by Moose Mountain Technical Services for Oroco and filed on SEDAR by Oroco. Accordingly, the Company is not treating this historical estimate as current mineral resources, as a qualified person has not done sufficient work on behalf of the Company to classify the historical estimate as current mineral resources. After the Oroco Technical Report was completed and filed, Oroco subsequently carried out a surface sampling and exploration and infill drilling program from December 2011 to April 2012, with a focus on the area south of the resource area which was the subject of the Oroco Technical Report. The Company expects to have a National Instrument 43-101 compliant technical report completed on the Cerro Prieto Project by approximately August 31, 2013. The Company’s technical report on the Cerro Prieto Project will incorporate the results of Oroco’s 2011 and 2012 exploration and infill drilling program, as well as a new geological interpretation, in order to update and verify the Oroco resource estimate as current mineral resources.
