Eagle Star Intersects High-grade Mineralization Near Surface and More Than Doubles Length of Mineralization at the Bomfim Project A1 Target

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb 28, 2013) - Eagle Star Minerals Corp. (TSX VENTURE:EGE)(ELGSF)(E6R.F) ("Eagle Star" or "the Company") is very pleased to announce that it has significantly increased the mineralized zone at target A1 by more than doubling its length to 570 metres (previously announced as 250 metres - see news release dated 12 November, 2012). Two pits opened to the south of scout drilling holes BRF-03 and BRF-15 along strike, based on targets developed from detailed mapping (1:10,000) and recent geophysical work in the area, suggest the mineralized zone extends significantly further.

Pit AM-01 intersected near surface, high-grade mineralization with XRF handheld readings of up to 15.37% P2O5 over 2.0 metres. Other results also show the continuity of mineralized envelopes at different cut off grades. Both pits end in the mineralized unit, which based on drill and geophysical results 200m to the north, may extend to over 20 metres depth (see press release dated February 26th, 2013).

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.

"These latest results from our A1 Target validate yet again the quality of work performed by our team in the field. Furthermore, the results confirm the value of information obtained through detailed mapping and geophysics and how important it is for our team to perform these tests over selected high-grade targets at our Bomfim Project," comments Dr. Campos, an expert in sedimentary phosphate mineralization and Technical Director of the Company. "I think the addition of these two pits in the northern block demonstrate the potential for the project to expand in scale as we move towards a resource calculation."
