Vancouver, British Columbia -- Metalline Mining Company (TSX: MMZ, AMEX: MMG) ("Metalline") is pleased to announce that Mr. Luc Stevenin has been appointed as Metalline's Country Manager in Gabon, Central West Africa.

Mr. Stevenin has over fourteen years experience living and working throughout West and Central Africa. Previously, he spent eight years working with Rio Tinto as their Logistics and Operations Manager in exploration projects in Guinea, Mauritania, Mali and Gabon, and until recently was managing the logistics and operations for the remote camp exploring the Zanaga iron deposit currently owned by Xstrata in the Republic of Congo. He has a combined degree in Geology and Geography from Kingston University in the United Kingdom and is fluent in French (the official language in Gabon) and English.

Tim Barry, President and CEO states, "Mr. Stevenin is a rare breed of character that excels in Africa and is the ideal person to be Metalline's Country Manager in Gabon. His fourteen years of experience working throughout the continent, including time in Gabon, coupled with his involvement in a number of world class projects from a grass roots level through to late stage exploration will be invaluable in pushing our African projects ahead."
