Eagle Star Minerals Corp. Acquires Mineral Concessions With High Phosphate Potential in the Parnaiba Basin, State of Piaui, North East Brazil

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 16, 2011) - Eagle Star Minerals Corp. (TSX VENTURE:EGE)(PINK SHEETS:ELGSF)(FRANKFURT:E6R) ("Eagle Star" or "the Company") is pleased to announce that it has received approval from the National Mining Agency of Brazil (DNPM) of its application for 39 mineral claims covering an area of 80,000 hectares in the centre of the state of Piaui – Northeast Brazil The concessions are located in areas with extensive phosphate potential.

The Phosphate occurrences are associated with the Pimenteiras shale formation located within the Parnaiba Basin. An arms-length party which includes Brazilian geologists has recognized this geological environment as having the potential for the occurrence of large scale phosphate and potash mineralization and has approached Eagle Star for the land acquisition. They carried out very detailed reconnaissance litho-geochemical rock chip channel sampling of the Pimenteiras formation outcrops for locating phosphate mineralization in the Parnaiba Basin. Over 222 samples were collected in an area measured 200 kilometres by 60 kilometres. Most of the samples were collected from outcrops along the main road or nearby access roads. The distance between the samples was variable and was consequence of local conditions, but on an average samples were collected every 3 kilometres. Each sample corresponds to a channel, perpendicular to the layers or bedding. The length of each was variable and averages 3 meters.

Three different highly anomalous areas were identified from the sampling. Claims totaling 80,000 hectares were staked to cover these anomalous areas.

• The principal anomalous zone has 180 km² (18,000 hectares) and returned values of 2-22% P₂O₅
• The second anomalous zone covers 340km² (34,000 hectares) and showed anomalous results of 3-10% P₂O₅
• A third anomalous zone covers 240km² (24,000 hectares) with lower results (2-5% P₂O₅) but should present higher values in a detailed sampling

The best results, mainly in the Paes Landim area, come from siltstone outcrops with phosphate nodules. The Pimenteiras siltstone formation is observed to be more than 12 meters thick based on the numerous outcrops in the area. The rock samples were analyzed by SGS Geosol Laboratorios Ltda (SGS) located in Vespaciano, Brazil. Detailed assay results from the three areas are shown below:

Geological studies suggest that the Pimenteiras formation was formed by cold water depositional environment. Most of the phosphate deposits in the world occur in sedimentary rocks like black shale, chert and carbonate rocks. The origin of these deposits is debated; most commonly they are associated with phosphate and nutrient rich cold upwelling currents (Kazakov, 1937; Cook, 1976; Sheldon, 1981). A possible tectonic control is suggested by its common association to marine transgressions (Strakhov, 1960; Mitchell & Garson, 1981).

Economic deposits usually show P₂O₅ (phosphate) grades ranging from 5 to 35%, most often as cryptocrystalline fluorapatite [Ca₅(PO₄)₃(F,CO₃)]. The most productive deposits are Upper Cretaceous to Eocene in age, located in Morocco, North Africa, and the Permian Phosphoria Formation in Idaho, USA (Blatt et al., 1991). The Phosphoria Formation is an example of a deposit associated to marine transgression presenting residual enrichment due to weathering of soluble phase (e.g., carbonate). The phosphate mineralization at Pimenteiras can also be compared to the Wonarah phosphate mine located in the Georgina Basin, Northern Australia. The Wonarah deposit hosts 485 million tonnes grading 18% P₂O₅

Brazil is one of the world's major agricultural producers. Agriculture represents one third of its economy, 42% percent of it is export based and is responsible for 17.7 million jobs (ANDEF, 2004). However, most of the soil in the countryside lacks Phosphorus (P), Potassium (K) and Nitrogen (N) and there are no economic viable deposits of sulphur. As the production of fertilisers has not followed the development of agriculture and livestock farming, the country became the 4^th major importer of fertilisers and 2^nd major importer of phosphate (Lapido-Loureiro et al., 2008), accounting for 51% of the phosphorous utilised in the country (www.cruzeirodosul.inf.br). In 2006, Brazil imported US$ FOB 1.170 billion in phosphate. This dependency is anticipated to increase continuously unless new domestic sources are found. Soils in the Brazilian Savanna are very depleted in phosphorous; this factor hinders long lasting and profitable agricultural activities without the application of phosphate based fertilisers. Therefore any locally produced phosphate from new mines will be consumed locally in Brazil.

The project area has excellent infrastructure consisting of roads, water reservoirs, power lines and a future railroad to be completed by the year 2013. In addition, Piaui state has a large agricultural base which includes soy plantations. Therefore any phospahate production will be consumed by local markets.

Eagle Star plans to commence next stage of exploration effective immediately. This will include mapping, systematic chip sampling and drilling.

The Company has agreed to pay project generation fees to the Arms-length party. In order to maintain 100 percent interest in the project the following fees have to paid to the party.

• issuance of one (1) million shares upon completion of first exploration stage (eight months) and commencement of second exploration stage subject to regulatory approvals (binding). 25% will be free trading effective immediately, additional 25% will be free trading within 6 months of issuance, further 25% will be free trading within 12 months of issuance and the final 25% will be free trading within 18 months of issuance.
• Cash payment of 500,000 Brazilian Reals within 6 months upon completion of 1^st exploration stage or 1 million Reals within 12 months upon completion of 1^st exploration stage or 3 million Reals within 24 months upon completion of 1^st exploration stage. Alternatively, the company can choose to make no cash payment in which case it will retain 90% interest in the project.

"This is a significant milestone for us as it is the first opportunity to be staked and wholly owned by the Company in Brazil," commented Eran Friedlander, President & CEO of Eagle Star Minerals Corp. "The Company's Brazilian team has been directly involved in the selection and claiming process as a result we are very confident about developing this project to production. With phosphate demand being strong in Brazil we believe that this new asset will add significant value to our portfolio."

Quality Assurance, Quality Control and Qualified Persons

SGS is a ISO14001:2004 and ISO 9001:2008 accredited laboratory. The samples were analyzed by fusion with lithium tetraborate-XRF for SiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, K2O, TiO₂, P₂O₅ and MnO and retained moisture (LOI) by multi-temperature. The MnO results are negligible.

SGS inserts its own standards, blanks and duplicate samples. The results from these control samples indicate acceptable consistency of analysis.
