PSL Prospero Silver Corp

Prospero Silver Corp. (TSX VENTURE:PSL) ("Prospero" or the "Company") is pleased
to announce completion of a detailed ground magnetic survey on two of its claims
over an area of approximately 9km x 9km in the "Western Lineament" zone of its
Santa Maria del Oro Project in Durango State, Mexico. Prospero controls 33,800
Ha in the district and has identified three distinct target areas: The Western
Lineament zone, the Matorral zone, and the Pastoria-Llanos de Cabrera valley.
Collectively, these target areas virtually surround the past-producing Magistral
del Oro high-grade gold mines (refer to Figure 1). The survey addressed in this
news release focuses on the Western Lineament zone. 


Data from the ground magnetic survey was independently reviewed by Wright
Geophysics and their full report can be found on the Company's web site. Two
large and distinct targets emerged from the survey in the Western Lineament zone
(see Figure 2):




1.  Two northwest trending lineaments 
    --  The "Magistral Lineament" is 12km long and exhibits east dipping
        structural controls, similar to the historic veins to the east.
        Drilling from east to west is required to investigate the structure
        at depth for vein-hosted mineralization. 
    --  The "Manantiales Lineament," further to the west, is 8 km long and
        represents a range-boundary fault which controls current hot spring
        activity. 
2.  Geophysical evidence (magnetic highs) of two large intrusive bodies
    under young gravels in the southwest portion of the surveyed area. An
    Induced Polarization/Resistivity electrical survey is required over the
    interpreted intrusions. Combined magnetic and IP anomalies would justify
    drilling under the gravel cover.  



1. The Lineaments. Prospero initially identified two lineaments under gravel
cover using aero-mag data from the Servicio Geologico Mexicano (Mexico's USGS).
The first and largest, the Magistral Lineament, is located 4km to the west of
the historic Magistral del Oro mines. 


The Company initiated a ground magnetic survey (200m to 300m line spacing) in
November 2011. The results from this survey were sent to Wright Geophysics in
Elko, Nevada, for processing and interpretation. Figure 2 shows the full extent
of the surveyed area and of the Magistral Lineament.


The magnetic model of the Magistral Lineament indicates the presence of a
magnetic body dipping at a shallow angle to the east along 5km of the
northwestern portion of the lineament, which exhibits a west flanking magnetic
low (Figure 2). Figure 3 (also taken from the Wright Geophysics report) shows
geologic contacts superimposed on the magnetics. Tan (andesites) and Tvr
(rhyolites) represent Tertiary volcanic strata which dip approximately 45
degrees to the west, opposite the dip of the structure responsible for the
lineament. Further to the southeast the west flanking magnetic low diminishes
and the lineament is observed as a change in the magnitude and texture of the
magnetics. This is interpreted as reflecting a steeper inclination in the
southeastern extension of the controlling structure, which then rotates to a
shallow easterly dip along its northwestern extension.


The geophysical interpretation of the shallow easterly dip of the Magistral
Lineament is similar to the dip suggested by historic mining records from the
historic Magistral del Oro mines. Inspection of a historic plan view and
longitudinal section of the Cocinera vein (and stopes) along 1,000m of strike
length indicates the structure has a shallowing dip from the northwest (70
degrees dip to the east) to the southeast (55 degrees dip to the east). The
largest mineralized body along the vein coincides with the shallowest (55
degrees to the east) 400m length in the southeastern extension of the vein.


Given the historic veins of the district exhibit similar strike (northwest) and
dip (to the east) as the Magistral Lineament, preliminary drilling from east to
west is justified to investigate the Magistral Lineament structure at depth. 


Mapping of the Manantiales Lineament (Figure 2) indicates the controlling
structure marks the boundary between conglomerates of the Sta. Ines
conglomerates to the west and Tertiary volcanics to the east. The lineament
represents a range-boundary fault, with active hot spring activity, that
downdrops the valley 50m to the west, with respect to the uplifted block to the
east. The potential of this structure to host mineralized veins is as yet
uncertain. 


2. Wright's report also identifies two possible intrusive bodies in the
southwest portion of the area (Figure 2), under the Sta. Ines conglomerates.
These prominent magnetic highs are interpreted as intrusions and the magnetic
model indicates a ... "geometry best described as a steep sided vertical
cylinder with depth to top of approximately 125 meters and radius of
approximately 1000 meters." 


The interpreted intrusions under gravel cover in the southwestern area of the
district will require an IP/Resistivity survey. A combination of magnetic highs
with electrical responses would justify drilling geophysical targets under the
young gravels. 




--  Veins from the old Magistral del Oro Mines host abundant pyrite in
    unoxidized ores. 
--  If zones of pyritization accompanied by mineralization are associated
    with the buried intrusions they could produce IP anomalies. 



"The results of the detailed ground magnetic survey carried out by the Company
support our initial appraisal of the sizeable magnetic lineament we identified
after processing the data from the Servico Geologico Mexicano. We are calling
the larger of the two lineaments El Magistral. The orientation is the same as
the old Cocinera mine 4km away and is typical of structures which host mines in
this part of Mexico," said Prospero President and CEO Tawn Albinson. "Wright's
report confirms our initial assessment that we have an east-dipping structure
that abruptly cuts off the westward dipping volcanic strata. The shallow
eastward dipping character justifies a preliminary drill program to investigate
the potential of the structure to host mineralized veins at depth."


Other Prospero Ground in the Santa Maria del Oro District

In March 2012, Prospero staked an additional 19,700 hectares to the north and
northwest of the historic Magistral del Oro mines covering two other areas of
interest. The Company now holds a total of 33,800 hectares that virtually
surround the historic Magistral del Oro mines. Records from these mines indicate
historic grades exceeded 15 g/t Au from oxide ores mined through the mid 20th
century. Semi-systematic sampling and detailed ground magnetics are in the
process of being completed in the northeastern extensions of the district, both
in the Matorral target area, as well as in the Pastoria-Llanos de Cabrera
valley. 




--  The Matorral target represents a high level N-S to NW trending dike
    complex and epithermal system at least 4kms in length. 
--  The Pastoria-Llanos de Cabrera valley hosts hydrothermalism associated
    with the top (paleosurface) of the hydrothermal system. 
--  Figure 1 also shows possible caldera-related circular structures
    (visible on Google Earth). 



Results of the mapping, multielemental geochemistry and the ground magnetic
survey in both target areas will be reported in coming weeks.
