Mr. Brian J. Maher, newly appointed President and CEO of Sienna Gold commented: “Following the sale of Prodigy Gold to Argonaut Gold in December of 2012, the Prodigy Gold senior management team evaluated literally dozens of business opportunities in the mining industry. The Sienna Gold story was compelling to us for many reasons: The Callanquitas Structure at the Igor project in Perú has a high quality gold-silver resource with room for significant expansion, project wide exploration potential is untested, and the geometry of the Callanquitas mineralization is ideal for a potential low-cost mining operation. It is clear that the Sienna Board and new management team, led by new Chairman Jorge Benavides, is highly motivated to advance the Igor project and build shareholder value. After a thorough evaluation of the Sienna story, the management team feels that Sienna Gold offers unparalleled potential to expedite an advanced project through the development pipeline, from resource estimation to pre-feasibility. We are excited to join Sienna Gold, and begin the process of building the Company and advancing the Igor project.”

Mr. Jorge Benavides, Chairman of the Sienna Gold Board of Directors, commented: “Sienna Gold is excited to have a management team the caliber of Brian, Tony and Kimberly Ann take the helm at Sienna. The success this team had at Prodigy Gold is well known in the mining community: Share price up five-fold and market cap up over ten-fold in 22 months, culminating with the sale of Prodigy to Argonaut Gold in December, 2012. On behalf of all Sienna shareholders, the Board looks forward to rapid progress at Igor, and on the Callanquitas Structure in the coming months and years ahead. I would also like to personally thank John and Gordon for all their contributions in bringing Sienna to this crucial stage and wish them the very best in their future endeavors”.
