COASTAL PACIFIC MINING ENTERS INTO NEW LOI

CALGARY, Alberta, February 4, 2011 - Coastal Pacific Mining Corp. (OTCQB:CPMCF) www.coastalpacificminingcorp.com, is pleased to announce that it has completed a letter of intent to enter into a joint venture for an additional silver prospect adjacent to its existing Santa Rita property, known as the Rica Plata 2 and 3 property (the “Property”).

Mr. Rick Walker, B.Sc., M.Sc., P.Geo., the Company’s geologist, will be returning to Peru to undertake a due diligence inspection of the Property and review any supporting documentation. The Company has up to 60 days to complete its due diligence and enter into a definitive joint venture agreement, during which period the final terms will be negotiated by the parties.

The Rica Plata 2 and 3 mineral tenure lies immediately south of, and is contiguous with, the Company’s previously acquired Santa Rita tenure. Together, the two tenures comprise an area of 1,600 ha (4,000 acres) and cover strata correlated to the Paleogene Sacsaquero Group and the underlying Cretaceous Casapalca Formation. The Casapalca Formation consists of medium- to coarse-grained, red-coloured arenite with interbedded conglomerate, while the Sacsaquero Group is comprised predominantly of welded rhyolitic tuffs, andesitic lavas and volcanic-derived arenites. These strata are well exposed in a southeast – northwest trending belt having, in part, a strong reddish-brown colouration.

The strong colouration, as noted on the property visit in early December, is the basis for the acquisition. Management believes the strong colouration may be indicative of hydrothermal alteration of the host strata. Vein and manto mineralization identified on the Santa Rita property has been interpreted as characteristic of a transitional Epithermal environment, resulting from hydrothermal activity associated with magmatism.

Limited sampling by Pasminco in 2000 returned weakly anomalous values from the northern edge of the Rica Plata 2 tenure, with maximum analytical values of 15.83 g/t silver, 155 ppm copper, 0.314% lead and 0.354% zinc. The samples were not taken from within the interpreted area of surface alteration and so the nature of this possible alteration zone remains speculative.

The 1200 hectares (2965 acres) Santa Rita property is located within the Central Cordillera of the Peruvian Andes in rugged terrain at elevations that vary between 4200 m (13,780 feet) to 4800 m (15,748 feet) above sea level. Limited exploration by Gateway and others has outlined vein and replacement mineralization hosted within the Jumasha Formation, which may continue at depth. The Jumasha Formation is regionally important in central Peru for its large volume skarn deposit potential.

Mr. Joseph Bucci, President of Coastal Pacific, commented “We believe that entering into this agreement will provide the Company with substantial efficiencies as we undertake our exploration programs, and establish production facilities as warranted. Upon our property expectations being borne out, we would be in a position to undertake significant levels of silver production.”

The technical information of this press release has been reviewed by Rick Walker, B.Sc., M.Sc., P. Geo and Qualified Person as defined by NI 43-101.

Note that no statement in this release is to be construed as there presently being actual or potential reserves identified on the Santa Rita or Rica Plata properties.
