Greencastle Identifies Priority Targets on Nechako Property, Blackwater Gold Area, BC


TORONTO, ONTARIO--(Marketwire - Nov. 3, 2011) - Greencastle Resources Ltd. (TSX VENTURE:VGN) ("Greencastle" or the "Company") is pleased to provide an update on progress at its Nechako property located in the Blackwater gold camp approximately 100 kilometres southwest of Vanderhoof, central BC. Greencastle has an option agreement to acquire a 100% interest in the property, covering approximately 13,000 ha (28 claims), on the Nechako Plateau.

The property is located in the same general Blackwater area where, in 2010, Richfield Ventures Corp. discovered a significant bulk tonnage gold deposit. In June 2011, Richfield was acquired by New Gold Inc. ("New Gold") for approximately $550 million. In a release dated September 16, 2011, New Gold estimated that, from drilling results to date, the discovery contained resources of some 6.6 million ounces of gold. On October 17, 2011, New Gold announced the acquisition of Silver Quest Resources Ltd. and Geo Minerals Ltd., further consolidating its position at Blackwater to the west and northwest. Greencastle's Nechako property is geologically on trend to the north of New Gold's Blackwater property.

A detailed heli-borne magnetic and EM geophysical survey has been completed by Fugro Airborne Surveys Corp. ("Fugro") to define targets for follow-up exploration on the Company's property. The airborne survey covered 1,487 line-kilometres, including tie lines. Flight lines were flown east-west with a line separation of 100 metres. The initial Fugro report has identified some 73 'high-priority' AEM anomalies based on favourable structure, magnetic association, conductance, length, width, or depth extent, as well as several more extensive conductive zones. Although some of these could reflect sulphide-type targets, most are considered to be of lesser priority, given the non-conductive nature of the expected auriferous target mineralization at Blackwater.

Due to the complexity of interpreting this style of gold mineralization from geophysical data, Greencastle engaged the services of Intrepid Geophysics Ltd. ("Intrepid") of North Vancouver, BC, to undertake a more detailed analysis of data collected by Fugro. This interpretation was based on an integrated analysis using a combination of GEOSOFT's integrated editors (spreadsheet and flight path), advanced Fourier filtering and multi-scale edge detection, ER MAPPER's image enhancements and MAPINFO's GIS capability. The Intrepid interpretation attempted to further discriminate these targets into a smaller grouping.

As a result of this work, a total of thirteen areas have been recommended for further investigation, initially by prospecting, geological mapping, rock and soil sampling.
