Metalline Reports on Eastern Extension of Area A Silver (+Zinc+Lead) Resource Area at the Sierra Mojada Project, Coahuila, Mexico

Greenwood Village, Colorado - Metalline Mining Company (AMEX:MMG, TSX:MMZ) is pleased to announce further results from the evaluation of earlier drilling programs at the shallow silver-zinc resource area ("Area A") at the Sierra Mojada Project located in Coahuila, Mexico. Results reported below are at a 30 gpt Ag or 1% Zn external cut-off. 

Metalline reports a total of 340 drill holes, most of them short underground "long" holes drilled in 2006 from access within the Area A silver (+zinc+lead) resource, that average 13 meters thick above a 30 gpt Ag cut-off, averaging 110 gpt Ag, 1.18% Zn, and 0.44% Pb. Most of these holes are only 2-22 meters long, and drill only a portion of the true thickness of the resource, which averages 25-30 meters thick in the area between sections 631700E and 632550E. This portion of the resource may be potentially minable from either underground or by open pit. If mineable by open pit the stripping to access this portion of the Area A silver(+zinc+lead) resource will expose the deeper and larger zinc oxide deposit and greatly reduce the stripping required to fully access the zinc oxide deposit.

Sections 631700E, through 632550E compliment assays sections that were reported earlier. Metalline has now reported assays sections covering the area between sections 629600E and 632550E on the Area A silver(+zinc+lead) resource, a distance of three kilometers, with a few intervening sections remaining to be compiled. The results from these remaining sections will be reported as compilation by section is completed. The continuity and potential minability of the silver zone on these sections is demonstrated on the individual graphic sections and the composite panel section diagrams posted to the web site at http://www.metallinemining.com/s/DH_Sections.asp.

All of the sampling and sample preparation for assays reported herein have been done on site under supervision by Metalline personnel and all those samples were shipped directly to ALS-Chemex for further sample preparation and assaying with insertion of appropriate standards and blanks. A third party review of the Company's QA/QC program vetted the Company's sample preparation and sample handling protocols for the previous core drilling and channel sampling programs, but did not specifically address sampling from the 2006 long hole drilling program. A surface core drilling program is planned for 2011 to test and confirm the geometry and grade of the resource area reported herein.

Greg Hahn, Interim President and CEO, a Certified Professional Geologist, is the Qualified Person responsible for reviewing and reporting the contents of this press release and assuring the results reported herein are in accordance with NI 43-101.
