VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 28, 2013) - 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 >19% P ₂ O _5. 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.

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."
