Magellan Extends Meio Zone At Coringa Project, Brazil
November 3, 2009
Vancouver, BC, November 3, 2009 -- Magellan Minerals Ltd. (TSX-V: MNM) ("Magellan") announces that prospecting to the SE of the Meio resource block at the Coringa project in Brazil has identified sub-cropping and outcropping veins and mineralized float extending over a distance of 1km immediately SE of the Meio zone (see map on website).
Rock chip, grab and float samples taken from the mineralized vein material both on surface and at depths of 0.5 to 2m confirms significant gold mineralization (1.02 g/t to 67.91g/t Au). Four of the widely spaced rock chip samples of the mineralized vein along 500m strike length, returned gold values greater than 16 g/t (see Table below and map on the Magellan website). The mineralized and oxidized vein material varies in width from approximately 30cm to 2m and dips vertically to 80 degrees to the NE. The nature of the oxidized vein material is very similar to that which is exposed on surface within the historic Meio workings located 1km to the NW. High grade gold values on surface are generally associated with steeply plunging high grade shoots at depth along the vein system at Coringa.
In addition to the discovery of sub-cropping high-grade vein material, recent soil sampling confirms gold in soil anomalies of 30 to 1,108ppb gold which extend for another 1.5km to the NW of Meio. The soil anomaly extends towards an undrilled artisanal working known as Mãe de Leite where historic workings extended to depths of 70m. The soil anomaly is coincident with the NW extension of a geophysical anomaly underlying the Meio resource block (see press release of October 8, 2009).
Both the high-grade vein structure to the SE and the soil anomaly to the NW of Meio confirm potential drill targets extending over at least another 2.5km.
Rock chip, grab and float samples with greater than 1.0 g/t gold.

Note: The above twenty-eight (28) rock samples represent 41% of the total sixty-nine (69) rock samples collected in August to September 2009. Gold values for the sixty-nine (69) samples ranged from less than 0.01g/t to 67.91g/t Au.
Rock and soil samples were sent via a secure transport agency to the SGS Geosol laboratory in Itaituba in Brazil for preparation and the pulps sent directly to the SGS Geosol laboratory in Belo Horizonte and Vespasiano for analysis. Gold analysis was by fire assay of a 30 g sample and an atomic absorption finish. SGS Geosol, which is an ISO, 9001:2000 and ISO 14001: 2004 registered laboratory has a quality control program in place, which includes standards and duplicates.
On 8th October 2009, Magellan announced an initial resource estimate at Coringa of 269,500 measured and indicated ounces of gold representing 982,291 tonnes at an average grade of 8.53 g/t gold and 98,224 inferred ounces of gold representing 327,054 tonnes at an average grade of 9.34 g/t gold on a diluted basis and using a 2 g/t gold cut-off. The identification of additional high-grade mineralization on surface immediately along strike from existing resources at Coringa suggests the presence of additional high grade, and thus far untested, ore shoots within the known vein system. A drill program is currently being finalized in order to test this new area SE of Meio and several previously untested areas along the known vein system.
Magellan expects to announce the commencement of a scoping study at Coringa by the end of November 2009.
