Coeur d’Alene, Idaho — Metalline Mining Company (Amex: MMG) announces the appointment of Greg Hahn to the board of directors, effective today.

Mr. Hahn is a Certified Professional Geologist and a geological engineer with more than 25 years experience in exploration, mine development and operation, and particular expertise in base and precious metals, ore reserve calculations, slope stability, open pit operations, project evaluations and investment analysis. He is a board member of Marathon PGM Corp. (TSX: MAR), and a principal of Greg Hahn Consulting, LLC, a mining and geological consulting firm. From 1995 to 2007, Mr. Hahn was President, Chief Executive Officer and Director of Constellation Copper Corporation (TSX: CCU), where he was instrumental in bringing the Lisbon Valley copper mine into production, and supervised the financing, construction and development of the mine.

Prior to Mr. Hahn’s position with Constellation Copper Corp., he was Vice President for St. Mary Minerals Inc. for four years and Chief Geological Engineer for CoCa Mines Inc. for five years, where he was involved in the construction and operation of two open pit heap leach gold-silver operations in southern California.
