San Marco Resources Inc. (TSX VENTURE:SMN) (the Company) has acquired by
staking, 156 sq. km of highly prospective land (Los Carlos II) adjacent to the
Company's 100% optioned Los Carlos property, where drilling is currently testing
the western portion of one of 4 known gold/silver surface occurrences. The Los
Carlos II property (15,600 ha.) is located in the prolific "Megashear" in Sonora
State, Mexico. Goldgroups Sierra Colorado mine is located 18km to the northwest
and Timmins Gold's San Francisco mine is 85 km to the east.


Regional reconnaissance by the Company's geological team has identified at least
4 separate areas of old mine workings including, pits, shafts, declines etc.
Initial surface sampling and mapping has been initiated on 2 zones; Emma Zone
(900 m x 400 m, open in all directions) and 5 km to the east, the JoJo Zone (250
m x 100 m, open in all directions). All areas sampled and mapped so far exhibit
classic Megashear low angle faulting and shearing typically found at most of the
producing mines in this trend.


The Emma Zone consists of Precambrian gneisses and metamorphosed intrusive rocks
which are overlain by a Lower Jurassic sedimentary sequence of sandstones, shale
and conglomerates. Two low angle structural systems have been identified and
mineralization appears associated with these structures. Chip/channel sampling
over 1-2 m has returned:




--  11.35 g/t gold and 12.6 g/t silver 
--  10.70 g/t gold and 4.10 g/t silver 



Select sample from shear/vein from an old decline:



--  18.9 g/t gold and 30.9 g/t silver 



300m to the SE, an open cut approximately 50m X 10m in oxidized sandstones, 1-2
m chip/channel samples returned:




--  0.96 g/t gold; 0.88 g/t gold; and 0.93 g/t gold. Silver ranged from 3.1
    - 7.3 g/t. 



The JoJo Zone, located 5 km to the east, has the Lower Jurassic sedimentary
sequence as the main mineralized host rock. Low angle faults dipping to the NE
host many old historical workings where stratabound mineralization in a sequence
of sandstone /limestone bedding returned:




--  1.7 g/t gold; 37.2 g/t silver; 2.9% zinc; 0.93% lead; select sample 
--  4.7 g/t gold; 65.4 g/t silver; 2.4% zinc; 1.77% lead; select sample 
--  0.31 g/t gold; 29.3 g/t silver; 1.74% zinc; 0.80% lead; 1 m channel
    sample 



Based on results of this first pass sampling program, a comprehensive full scale
exploration program to include, trenching, soil geochem, and geological mapping
is being prepared.


Chairman Robert Willis, stated, "With this sizable land position in such a
highly prospective area of the Megashear, San Marcos geological team is poised
to explore the entire property and investigate other old workings known to
exist. The Emma and JoJo zones appear to have indications of significant grade
and size potential. Some of the geological and structural characteristics that
we are learning from the Los Carlos drilling can be applied to ongoing
exploration in this newly acquired property."
