Eagle Star Proves Strong Correlation Between Geology and Geophysics as it 
Encounters Additional High-Grade Pit Intersections at Bomfim
Target D1 (PZE South Portion) 
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/28/13 -- Eagle Star
Minerals Corp. (TSX VENTURE:EGE)(PINKSHEETS:ELGSF)(FRANKFURT:E6R)
("Eagle Star" or "the Company") is pleased to announce that
additional pit testing conducted along line 9 (L9) at Target D1 (PZE
South) has confirmed the presence of high-grade phosphate which
demonstrates a strong correlation between geophysical data and the
geology at Target D1. This information lends further support to the
effectiveness of the geophysical method used as a means to identify
areas of high-grade phosphate mineralization above the dolomite
bedrock. 
Three pits were opened based on interpretation of data collected
through geophysics along a 350 meter section on line 9 (L9). All pits
returned excellent grades of phosphate including Pit-GEOF-03 which
intersected 4 meters of high grade material that exceeds the hand
held XRF limit of greater than 19% P2O5. In each case, the pits
remain open at depth and the grades appear to increase in value the
deeper the pits were channel sampled. The depth at Pit-GEOF-01 was
restricted to 2.6 meters due to the hard nature of the phosphorite
rock in that location which limited further manual excavation.
Additional pits are scheduled to be opened with the objective of
compiling the necessary data to statistically correlate between
geophysics and the genetic model while also continuing to assist with
the NI 43-101 resource calculation.

(i) Grades exceed the limit of the hand held XRF device.                  

 
XRF readings were collected systematically following recommended
procedures of the manufacturer, Innov-X Systems. Pits are channel
sampled along meter intervals and for each sample three readings are
collected and averaged. Prior to analysis, the sample collected is
homogenized, dried (using microwave oven) and manually crushed to
fine grain. The composite grade for the pit is reached by weighted
averaging of the values obtained for each sample. The handheld XRF
analyzer is an Olympus Delta model and was calibrated according to
Innov-X Systems in-house calibration procedure. The Company conducts
field XRF analysis using industry recognized sample preparation and
analysis protocols, and has conducted sufficient quality control
using the XRF method to believe that although the method cannot be
relied upon to have the equivalent precision and accuracy of a
certified analytical laboratory, the results are of sufficient
quality to direct exploration pending analytical laboratory
confirmation. 
Based on the results of the geophysical study and the information
collected from the pits opened, the mineralized section along Line 9
is interpreted to stretch over a distance of at least 1300 meters in
an east-west direction and the boundary between the underlying
dolomite and the overlying phosphorite mineralization is interpreted
to extend up to 20 meters in certain areas.

Due to the excellent results obtained from Geophysical work, Eagle
Star has decided to extend the geophysical survey further East by
acquiring an additional 3 km of ground geophysics to a total of 16 km
in the PZE South portion. To date, 70.5% of the originally planned
13km of geophysical survey has been completed and now awaits
interpretation. 
FURTHER DEVELOPMENTS 
The company is pleased to announce that it has completed the ground
topographic survey at the PZE South portion which was carried out
using total station survey equipment with measurements recorded every
25 meters. The final product is a Three Dimensional Elevation Model
to be utilized by geological, geophysical and geochemical modeling of
the PZE South portion. Scheduled drill holes will also be surveyed
after completion.  
CONCLUSIONS 
"We are very enthusiastic as a result of these recent developments.
Geophysics has proven to be a very important tool for us to better
understand the geology and potential of PZE South portion in
preparation for the NI 43-101 resource calculation planned for that
area," comments Dr. Campos, an expert in sedimentary phosphate
mineralization and Technical Director of the Company. "Everyone in
the field is now very much looking forward to further test the data
received from the geophysics by way of drilling."
