VANCOUVER, BRITISH COLUMBIA--(June 14, 2012) - Eagle Star Minerals Corp. (TSX VENTURE:EGE) (PINKSHEETS:ELGSF) (FRANKFURT:E6R) ("Eagle Star" or "the Company") is pleased to announce the identification of an area within the Samba Project that combines high grade phosphate with Rare Earth Element (REE) mineralization.

To date, the follow up sampling program at Samba helped define three areas (Samba North, Samba West and Samba South) of high potential.

The newly discovered high grade phosphate and REE zone is located within the Samba North area where a thorough analysis of the best P2O5 results (up to 26%) revealed a combined mineralization with total REE of up to 0.5%, a grade which is considered to be excellent in world class Paleoplacer REE deposits.

GEOLOGY AND RESULTS SAMBA NORTH

The topographic pattern of the Samba North area is characterized by an elongated, north-east oriented ridge that reaches up to 250 m in elevation and has approximate dimensions of 7km by 1.5km. The excellent results obtained to date are located in the northern limit of the ridge and therefore the mineralization is open laterally along the ridge.

The rock types mapped are the purple siltstone, phosphorite layers (locally brecciated) and sandstones. The field evidence suggests a repetitive intercalation of the siltstone and sandstone, which seem to vary in thickness from 10 to 20 meters. The phosphorite layers occur within the siltstone packages and host high-grade phosphate and REE mineralization. The phosphorite layers reach up to 40cm in thickness and are found on three different topographic levels suggesting a repetitive nature. The brecciated type is probably related to lineaments (faults). Highlights of the chip sample results from the Samba North area are shown below:

Consequently, they may be to some degree selective and may not be representative of mineralized units.

The bordering area of the Samba North ridge is a siltstone with P2O5 grades of up to 5% (based on channel samples of 1 meter taken at surface from outcrops). The area is relatively flat and the mineralization is open to depth. The best channel sample results to date are listed below (REE results are pending):

FURTHER WORK AT SAMBA NORTH

Detailed mapping will be conducted at the Samba North area to define the stratigraphic sequence, estimate the thickness of each rock type package and map the phosphorite layers. Additional sampling of the phosphorite layers and of the sandstone will be carried out to verify the solubility of the phosphate. Description of thin sections will define the phosphate and REE mineral bearing phases (Xenotime, Britholite, Monazite).

A total of 28 pulps were selected to run REE analysis (results are pending). The samples were chosen based on the rock type and the geochemical parameters shown in the table below:

Element Lowest Highest Average Th(ppm) 20 641 173 Y (ppm) 40 1001 249 U (ppm) 21 452 179 P2O5 (%) 1.2 17.8 5 La (ppm) 30 181 64 Li (ppm) 10 79 24

SAMBA SOUTH AND SAMBA WEST AREAS

The Samba South area is dominated by grey and purple siltstone rock types. Chip samples taken to date returned grades of up to 4.8% P2O5 (REE results are pending).

The Samba West area is dominated by the
