COEUR D'ALENE, Idaho, Aug. 4 /PRNewswire-FirstCall/ -- Metalline Mining Company (NYSE Amex: MMG) is extremely pleased to announce the start of a 4000m diamond drilling program in August on its Ndjole and Mevang Exploration licenses in Gabon, Central Africa. The drilling program will be conducted under the direction of Joint Venture partner AngloGold Ashanti. The Ndjole and Mevang permits cover rocks from two adjacent sedimentary basins which comprise of a sequence of deformed sedimentary and volcano-sedimentary rocks that are early Proterozoic in age. Three prospective zones for gold exist within these licenses; the La Mboumi, Ebel, and Mianga prospects. Details and an update on the project and the exploration areas are available on the web site at www.metallinemining.com/gabon.html. This initial drilling program is a follow-up on three large soil grids, each in excess of 10km x 5km in size and which comprised of over 2500 samples, which targeted areas with known mineralization and favorable geology. Results from these grids were then followed up with 4 infill soil grids and targeted geological mapping aimed at better defining the anomalous zones. In a testament to Metalline's team in Gabon, a total of over 13,000 samples have been taken in steep terrain and dense jungle since the start of the year. Three main coherent gold anomalies above 50ppb over 5km in length and up to 1.5km wide and several smaller anomalous zones up to 2km in length and up to 1km wide have been identified. Background gold values in the region are less than 5ppb and results above 20ppb are considered anomalous. Over 25% of the results received to date are above 30 ppb with peak values in excess of 5000ppb in the soils. The anomalies appear to have strong structural controls - concentrating along mapped or inferred lithological contacts, structural breaks, and fold hinges. There is also a strong spatial relationship of the gold anomalies to a thick graphitic lithological unit in the area which is thought to represent an ideal lithological trap for mineralizing fluids. Initial prospecting in these anomalous zones has identified a number of gold-arsenopyrite bearing quartz veins, many of which run between 2 g/t to 5 g/t gold. A man-portable diamond drill from E-Global Drilling recently arrived into the country and has been transported to site, with drilling expected is to commence in the first week of August. A 4000m drilling program composed of 4 drill lines with a combined total of 20 holes to 200m depth is currently planned.
