Metalline Mining Company (NYSE Amex: MMG; TSX: MMZ) has announced further drilling results from the ongoing 2010 and earlier drilling programs at the shallow silver-zinc resource area 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 another 57 drill holes that average 27 meters thick above the 30 gpt Ag cut-off, averaging 91 gpt Ag, 1.68% Zn, and 0.31% Pb. Altogether, Metalline has now reported a total of 115 drill holes that average 35 meters thick above the 30 gpt Ag cut-off, averaging 84 gpt Ag, 1.32% Zn, and 0.26% Pb. The average thickness and grade remains very consistent across what is now 115 holes covering more than 1500 meters of strike length with an additional 500 meters of strike length yet to be reported, and another 1000 meters of strike length not yet drilled.
Sections 631200E, 631300E, and 631600E complement sections 631400E and 631500E that were reported early. Combined these sections cover 500 meters of strike length and demonstrate excellent continuity between sections of the +30 gpt Ag outline as well as a higher grade core area of +100 gpt Ag. This is in addition to the sections covering 629600E to 630600E covering over a kilometer of strike length on the western end of the deposit.
All of the sampling and sample preparation for assays other than the B10000-series holes reported herein have been done on site under supervision by Metalline personnel and all those samples and samples of sawed core from the 2010 drilling program were shipped directly to ALS-Chemex for further sample preparation and assaying with insertion of appropriate standards and blanks. QA/QC on all of the assay data reported here has been completed by Nick Suter, Chief Geologist at the Sierra Mojada Project. QA/QC of the remaining drill holes has been contracted to IOGlobal, an international and independent QA/QC consulting firm, to expedite review, approval, and turnaround of the remaining assay data.
Metalline wishes to correct typographical errors that appeared in the November 3, 2010 press release on drill hole assay results. The previous press release referenced a distance of "1300 kilometers" between sections. That should have read "1300 meters". In addition, average silver grades by section were referenced as "2.3 ounces per tonne" and "0.93 ounces per tonne". Those should have read "2.5 ounces per tonne (metric)" or "2.3 ounces per ton (short)" and "1.02 ounces per tonne (metric)" or "0.93 ounces per ton (short)", respectively. In this instance, the average silver grades reported above of 91 gpt Ag and 84 gpt Ag are equal to 2.92 ounces per tonne (metric) and 2.69 ounces per tonne (metric).
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.
