San Marco Discovers Significant Gold Zone at Tecomate, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 26, 2011) - San Marco Resources (TSX VENTURE:SMN) is pleased to announce an update of exploration activities at its 100% owned, 12,300 ha, Tecomate property, located approximately 81 km east of Mazatlan.

Recent exploration has focused on the Main and NW Zones, where gold and minor amounts of silver, lead, zinc and copper, have been discovered in trenches, channel and rock chip samples. Mineralization is associated with a near vertical 200m wide, northwest striking shear/fault structure hosted in the Tertiary Lower Volcanic rock package. At surface, the central 80m of the structural corridor, is covered by a stratigraphic layer of rhyolite tuff with limited mineralization. Surface outcrops on each side of the rhyolite tuff in highly oxidized rocks returned:

  • 1.19g/t gold; 0.24% zinc over 60 meters (western slope).
  • 0.69g/t gold; 0.28% zinc; 0.24% lead over 60 meters (eastern slope).

These results are a compilation of samples taken over a 50m wide, E - W cross section in the central portion of the currently known 420m of strike length. (See cross section on company website www.sanmarcocorp.com).

Two old gambosino adits have been discovered on the western slope of the Main Zone mineralization. These tunnels were apparently constructed to cross cut into the main structural zone. The "Troze" tunnel is approximately 150 vertical meters below the above noted surface mineralization. As the workings progressed toward the Main Zone structures, gold mineralization increased, where the last 10m of the adit assayed 0.38g/t gold. The San Pedro adit 100 vertical meters below the surface also appears to have just been approaching the Main Zone, and the last 10m also assayed 0.38g/t gold. Of note, sampling of a dike at the end of the Troze tunnel, returned:

  • 1.08g/t gold; 17.0g/t silver; 1.3% lead; 2.6% zinc and 1.2% copper over 2 meters.

San Marco Chairman Robert Willis stated, "We are extremely encouraged to find evidence that mineralization has at least 150m of vertical extent. With mineralization known to exist over 420m of strike, and 200m width, the Main Zone has demonstrated some size potential." Exploration at Tecomate is continuing in the NW Zone located 2 km from the Main Zone. It is believed that this area may be one continuous structural corridor.

The Main Zone has developed into a solid drill target as has the NW Zone. Continuing exploration at the La Guera-Horcon area, some 3 km to the southeast also has returned indications of gold values up to 3.0g/t. These gold values are associated with boiling textures in porphrytic rocks. This could indicate the Horcon area is much higher in the mineralized system. Upon completion and data compilation of all areas of the property currently being explored, drilling is expected to initially test the Main and NW Zones.
