COEUR D'ALENE, Idaho, Feb. 27 /PRNewswire-FirstCall/ -- Metalline Mining Company (AMEX:MMG) announces selected drill hole results representative of the silver rich Polymetallic Manto mineralization north of the Sierra Mojada fault. Diamond drill hole D1061212, in the Plaza Rica area of the San Salvador mine, assayed an average of 129 grams silver per tonne and 3.8% zinc over an interval of 54 meters from 15 to 69 meters depth in the hole. Additional drill results from this area, the Plaza Rica, were announced in press releases dated May 11 and 24, 2006 and from drilling west of the San Salvador shaft in a release dated November 21, 2007. Diamond drill hole D1070908, in the Encantada mine, assayed 87 grams of silver per tonne and 6.4% zinc from 138-162 meters in the hole, an interval of 24 meters. Drill hole D1070809, in the same part of the mine, intersected 10 meters of mineralization averaging 250 grams silver per tonne and 0.14% copper, with economically insignificant zinc and lead, from 171 to 181 meters. This hole also encountered four other widely spaced mineralized zones. All of the analytical results reported above were provided by the ALS Chemex laboratory in Vancouver, Canada. The Company moved one of its smaller Termite diamond drills into a drill base in the La Nortena area of the Encantada mine on January 7th. The samples from the first of these holes have just been received in the processing stream at the ALS Chemex laboratory. We expect these samples to be very encouraging. A three dimensional evaluation of the silver, copper, zinc and lead drill hole and channel sample data collected to date in the Polymetallic Manto located in the San Salvador, Encantada and Fronteriza mines is in progress. These data are collected over a distance of 1500 meters that is parallel to and north of the Iron Oxide and Smithsonite Manto oxide zinc mineralization, south of the Sierra Mojada fault. We are working towards obtaining a bankable feasibility study on the oxide zinc mineralization. Metalline Mining Company is an exploration stage enterprise engaged in the business of mining.
