Prospero Silver Corp.: Soil Grid Sampling at El Petate Expands Target Areas

Prospero Silver Corp. (TSX VENTURE:PSL) ("Prospero" or the "Company") is pleased
to announce the results of a further 487 soil samples obtained in the Petate
East sector of it's 6,000 hectare El Petate project. The grid is in addition to
the rock chip assays from the previously reported Petate West (Apartadero) zone
and was carried out over the Petate #1, #2, #3, and #4 target areas over a total
length of 2 km as shown in Figures 1 to 4. The eastern sector demonstrates
proportionately high silver values than Apartadero.


As described in the news releases of October 18, 2012, and January 21, 2013,
outcrops and float of jasperoid and gossan have been extensively mapped as shown
in the attached figures. The jasperoids and gossans exhibit a predominant
northwest structural control and dips to the southwest. The highlights of the
soil geochemistry include: 




--  Silver anomalies greater than 5 ppm and up to 52.3 ppm are prominent in
    the Petate # 1 and #2 target areas. In both areas the anomalies are open
    to the west particularly in the western (hanging wall side) of the
    Petate #2 target where the highest silver values (52.3 ppm, 37.4 ppm,
    and 19.9 ppm) were obtained (see Figure 1). 
--  The gold geochemistry is highest in Petate #3 target (up to 0.334 ppm)
    particularly where outcrops of gossan are exposed along 50 meters in a
    creek (Figure 2). A subdued gold anomaly extends an additional 400
    meters to the northwest which is also reflected in the mercury (Figure
    3) and iron geochemistry (Figure 4). 
--  Iron anomalies are skewed towards the northern Petate #3 target where
    values are commonly greater than 3.5%, in contrast to Petate #1 and #2
    targets which generally revealed values less than 3%. 
--  Antimony and arsenic are also highest towards the Petate #3 target with
    antimony values commonly in the 30-68 ppm range and arsenic values in
    the 100-1795 ppm range. 
--  Barium and manganese are proportionately higher in the Petate #1 and #2
    targets: 
    1.  Barium is in the 400-1860 ppm range, and 
    2.  Manganese is in the 4,000 to 16,000 ppm range. 
--  Nearly all elements are low in the area in between el Petate #2 and #3
    targets where outcrops and suboutcrops of an andesite intrusive is
    mapped (see Figures 1, 2 and 3). 



The following next-step activities are now considered for the Petate East zone:



--  Extend the soil grid program west of the Petate # 1 and Petate # 2
    targets to close off the silver anomalies, which are open in that
    direction. 
--  Carry out trenching in the best anomalies to better define the location,
    size and geochemistry of the targets. 



In summary, the soil grid survey has proven valuable in showing that the Petate
#3 target area extends further to the northwest, and also indicates the Petate
#1 and Petate #2 anomalies are open to the west.
