San Marco Samples 83.4m of 1.44 g/t AuEq at Tecomate

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 7, 2011) - San Marco Resources (TSX VENTURE:SMN) (the Company) reports significant trench results from its 100% owned Tecomate property in Mexico. Recent exploration has focused on an area located 750m northwest from the Main Zone (see company website for details). Geological mapping of the 200m wide shear structure indicates this zone is continuous with the Main Zone, resulting in approximately 1.2 km of strike, and still open.

Highlights of continuous 2.5m rock chip samples in trenches include;

• 83.4m grading 0.56 g/t gold and 40 g/t silver; or 1.44 g/t AuEq*.
  This trench includes; 36m grading 0.96 g/t gold and 49 g/t silver; or 2.04 g/t AuEq*.

One additional trench located 100m south east of the above trench reported;

• 13m grading 0.25 g/t gold and 18 g/t silver; or 0.65 g/t AuEq*.
  This trench is open and additional sampling will continue in both directions.

* AuEq is calculated using $1000/oz gold and $22/oz silver.

* metallurgical recoveries presumed to be 100%

These new results compliment the previously reported (May 26, 2011 news release) trench results in the Main Zone of 60m grading 1.19 g/t gold (western slope) and 60m grading 0.69 g/t gold (eastern slope).

Also, previously reported high grade sample results (July 19^th, 2011 news release) from the La Verdosa area, 6.2m of 117 g/t silver, 1.04% copper, 3.7% zinc, 1.0% lead, and 0.12 g/t gold, have indicated discovery potential of several different types of mineral deposits at Tecomate.

In preparation for drilling the Main Zone, NW Zone, Main Zone west extension and La Verdosa, crews are upgrading access roads, preparing camp and support facilities and continuing to explore additional mineralized areas in and around current surface showings.

Phase 1 drilling will consist of 3000 meters and is expected to commence in 3 weeks. A second drill will arrive on site in late October.
