Eagle Star Intersects 17.41% P2O5 Outside the Originally Estimated High-Grade Phosphate Zone at the East Portion of Bomfim Hill

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 20, 2013) - Eagle Star Minerals Corp., (TSX VENTURE:EGE)(PINKSHEETS:ELGSF)(FRANKFURT:E6R) ("Eagle Star" or "the Company") is very pleased to announce that hand held XRF results from Pit-11 has returned 2m @ 17.41% P₂O₅ average grade (from 2.1 to 4.1 meters and remains open at depth). Pit-11 was opened outside of what was originally estimated to be the high-grade zone at the Eastern portion of Bomfim Hill (Phosphate Zone East - PZE).

Upon successful intersection of high-grade phosphorite at Pit-11, two additional pits were opened even further north. They too have intersected high-grade phosphorite. Together, these three pits confirm that the high-grade mineralization at the Eastern portion of Bomfim Hill now extends over a longer strike then originally estimated while it is still open in all directions. Pit-12 returned XRF readings of 3m @ 7.43% (from 2.0 to 5.0 meters, including 1m @ 9.92% P₂O₅, open at depth) and Pit-13 returned XRF readings of 1m @ 10.19%P₂O₅ (from 2.0 to 3.0 meters, open at depth). Due to the hard nature of the phosphate rock found in this northern area the team was not able to reach its target depth of 5 meters in each pit by way of manual digging. Drilling is therefore required to fully test these pits at depth and to continue with exploration further north.

The 6 pits reported here in the north portion are aligned over 300m and extend mineralized continuity along strike to at least 1.5 kilometers. The results from Pit-11, 12 and 13 also further strengthen Eagle Star's geological model that suggests grades of phosphorite rock will increase at depth due to decreased exposure to weathering. This trend is supported by all other pit results announced to date.

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.

CONCLUSIONS

"We are very excited about these developments. To further extend an already sizeable mineralized strike comes as a complete bonus and just goes to show how substantial the Bomfim discovery is shaping up to be." Commented Eran Friedlander President & CEO Eagle Star Minerals Corp. "With plans for early production focused on the east side of Bomfim Hill (PZE) it is clear how this new discovery can bring significant value to the company in the short term".
