("Tintina" or the "Company") (TSX VENTURE:TAU) is pleased to announce that it has appointed Mr. Henry Park as a director of Tintina. Henry Park is a Managing Director of Electrum Frontier. Most recently, Henry Park was the lone commodities analyst at Soros Fund Management responsible for all investments in metals, mining and agriculture. His responsibilities were to conduct research on macro commodity trends, and to analyze public and private metals, mining and agriculture companies. He started his career in commodities within the Wingspan platform of Ospraie Management. Prior to going on the commodities path, he was with GE Capital in the distressed debt business and Morgan Stanley as an M&A investment banker. Mr. Park holds a Masters in Business Administration from Columbia University (2006) and a B.A. in Economics from University of Chicago (1998).

In connection with this appointment, the Company has granted 100,000 stock options under the Company's Stock Option Plan to Mr. Park, subject to regulatory approval. The options, which vest over a period of two years, will be exercisable for a period of five years.

The Company also announces that Ms. Terry Penstock and Mr. Larry Buchanan have tendered resignations as directors of the Company, effective immediately, in order to devote more time to other business commitments, respectively.

On behalf of the Board for Directors, Rick Van Nieuwenhuyse, Tintina's Chairman, commented: "We would like to thank both Terry and Larry for their valuable contributions to Tintina in its formative years. Both are very busy people, and we appreciate their time and effort to help get Tintina to where it is today – a well-financed exploration company developing a high-quality copper-cobalt-silver asset at Sheep Creek, Montana. We thank you and wish you well in your future endeavors. Meanwhile, we welcome Henry Park to the Board of Directors. His experience as a metals analyst and his Wall Street contacts will be well-utilized as we move this exciting project through the value chain and towards production. With copper over $4 dollars per pound, good quality copper assets are attracting a premium valuation, and with Sheep Creek's ideal location and nearby infrastructure, Tintina is advancing this project to a production decision as quickly as possible."
