Castle Resources Reports Significant EM Anomalies Identified by 3D Analysis

TORONTO, ONTARIO -- (Marketwire) -- 02/27/13 -- Castle Resources Inc. (TSX VENTURE: CRI) ("Castle" or the "Company") is pleased to provide investors with the exciting findings of a recent 3D geophysical analysis conducted on Castle's entire land package in northwest B.C., anchored by the past producing Granduc Copper Project.

"This latest analysis of electro-magnetic work on our land package in northwest B.C. has indicated some very exciting drill targets," stated Mr. Mike Sylvestre, President & CEO of Castle Resources. "These very conductive zones indicate a larger area of potential mineralization not previously recognized."

Preliminary 3D inversion modeling and interpretation of the 2010 airborne Aeroquest AeroTEM III geophysical survey data by the consulting firm Caracle Creek International Consulting Inc, made the following observation concerning two new electro-magnetic (EM) conductive bodies, known as the North EM Zone and Tunnel EM Zone (see Figure 1 for EM locations in relation to the Granduc Copper Project).

North EM Zone:

An extensive conductor has been identified along the southern face of the area roughly 3.5 km north east of the JK Zone (termed the North EM Conductor). This feature trends north-south, exhibits a conductivity greater than 13 mS/m and extends over a strike length exceeding 2 km, dipping approximately 15 degrees to the south. This feature extends to surface at location (NAD 83 UTM Zone 9) 419235 E, 6234560 N, and the majority of the feature begins 200 m below surface, representing a potential near-surface drill target. This conductive feature is located within a magnetic low and bounded to the east by a magnetic high (0.01 nT). (Figure 2)

Tunnel EM Zone:

A moderate EM conductor (5-7 mS/m) has been modeled at 10 km along the Tunnel (as measured from the eastern portal entrance). This conductive feature trends north-south over a 1.2 km strike length and is positioned 200 - 400 m above the tunnel itself. The feature dips approximately 30 degrees to the northeast and has been modeled as doubly-plunging to the southeast (20 degrees) and northwest (25 degrees). This conductive feature is located within a magnetic low (less than 0.002 nT). (Figure 3)

"These massive geophysical anomalies will be drill tested this field season," stated Mr. Brad Leonard, Castle's Exploration Manager. "The 2 km long north EM conductor north east of the JK Zone appears to be related to the South Unic Shear Zone, which has been interpreted to represent a major disconformity between the older Triassic rock that host the Granduc deposit and the younger Jurassic rocks that are host to many of the gold deposits in the Stewart area including Pretivm, Scottie Gold, and Eskay Creek."
