COEUR D'ALENE, Idaho, Nov. 27 /PRNewswire-FirstCall/ -- Metalline
Mining Company (AMEX:MMG) has received the following drill results
for diamond drill holes drilled to continue evaluating the oxide
zinc mineralized area located two kilometers west of the Iron Oxide
Manto in the San Salvador, Encantada and Fronteriza mines. As
previously announced a feasibility study is in progress on the Iron
Oxide Manto mineralization. Seven diamond drill holes were
completed from four drill sites that tested an area approximately
250 meters East-West and 200 meters North-South. Five holes
intersected mineralized intervals of economic interest, two holes
did not intersect mineralization of economic interest and one hole
is still pending assays. A total of 13 holes have been drilled by
North Limited, Penoles and Metalline in this area. Hole D5060622 is
offset about 5 meters east of Penoles' SMW4A hole. The
mineralization in D50622 occurs at a higher elevation than the
mineralization in SMW4A indicating a probable fault offset of
mineralization between the two holes. D5060622 confirms
mineralization of economic interest, additional drilling is
required to determine the distribution and potential of this
mineralization. SMW4A 371.25 TD D05060622 From To Zinc % From To

area mineralization is near surface and consequently is amenable to
open pit mining. Open pit mining is lower cost than underground
methods and allows mining very low grade mineralization. As an
example, San Cristobal, located in Bolivia, is currently under
construction and projected to be in production in 2007 with
announced reserves of 219 million tonnes proven and probable, with
grades of 64.7 g Ag/t, 1.6% Zn and 0.6% Pb. Open pit production is
targeted at 40,000 tonnes per day. Drill Hole Summary Table Sierra
