TORONTO, Oct. 25, 2007 (PRIME NEWSWIRE) -- Eastmain Resources Inc. (TSX:ER) (Other OTC:EANRF) is pleased to announce additional assay results from the JT Gold Target area at the Eleonore South project, its JV option with Les Mines Opinaca Ltee, a wholly owned subsidiary of Goldcorp Inc. (TSX:G) (NYSE:GG) and Azimut Exploration Inc. (TSX-V:AZM).
Additional channel samples in the JT Target area taken by Eastmain, the project operator, have confirmed a large sedimentary gold zone with significant discovery potential. The JT Target covers an area 300 metres wide by 600 metres long consisting of sedimentary rocks highly enriched in gold. Eastmain interprets the JT target area as geologically and mineralogically comparable to the setting at Goldcorp's nearby Roberto gold deposit.
783 channel samples received to date are from the JT Target Area. One-third of these samples are enriched in gold. As reported in a previous news release (Aug. 30, 2007), a section of the JT Target containing visible gold, referred to as the VG Zone, has been traced in outcrop for a length of 11 metres in Trench ELS-07-1E3. Wide intervals of gold-bearing, siliceous, sedimentary rock containing disseminated arsenopyrite, flanking the VG Zone, include assays of 5.33 g/t Au across 8 metres and 10.9 g/t Au over three metres.
JT Target Area (783 one-metre channel samples; 7 trenches)
* 33% of all samples are enriched in gold, indicating a potential ore-forming system in the vicinity; * 108 channel samples range from 0.5 g/t Au to 37.8 g/t Au; * 54 channel samples contain more than 1.0 g/t Au; * 3 channel samples contain over 20 g/t Au; * The VG Zone includes one-metre assays of 37.8 g/t Au, 31.2 g/t Au and 5.33 g/t Au over 8 metres; * The area flanking the VG zone assayed up to 10.9 g/t Au over 3 metres, including a one-metre sample at 22.9 g/t gold; * Multiple assay intervals range from 0.79 g/t Au across 5 metres to 1.27 g/t Au over 10 metres.
Thirty-five trenches, based on coincident geochemical, geophysical and/or geologic targets, within the 10-kilometre-long gold-in-soil anomaly outlined in 2006, have been excavated for a combined length of 5,063 metres. From this, approximately 4,183 metre-long channel samples were collected. Assay results for 1,648 one-metre-long channel samples have been received to date and results from over 2,000 additional channel samples are pending.
During the 2006-2007 field season, 194 line kilometres of Gradient IP (Induced Polarization) surveys, covering a 12.2-kilometre strike length, were completed across sedimentary rock formations coincident with the property-wide, gold-arsenic soil-geochemical trend. 48.5 line kilometres of follow-up detailed dipole-dipole IP surveys, over 12 target areas outlined by the gradient survey, included the JT Target.
The purpose of the IP surveys was to detect buried metallic sulphide deposits within the sediments. Gold at the Roberto deposit is accompanied by arsenopyrite, a metallic sulphide. Gold-enriched sediments in the JT Target area also contain accessory arsenopyrite. Gold and arsenic assay data from the JT Target confirms the potential for a sedimentary-hosted gold deposit at Eleonore South.
A comprehensive drill program, proposed as the next phase of work, will test the JT Target area and up to 25 targets elsewhere on the property. Fieldwork is performed under the supervision of Frank Kendle, P. Geo. This press release was prepared by geologist Dr. Donald J. Robinson, P. Geo, qualified person as defined by National Instrument 43-101. Rock samples were analyzed by fire assay methods at ALS Chemex Ltd.
The Eleonore South project is located immediately south of Goldcorp's Eleonore project, which includes the Roberto gold deposit.
Eastmain is a Canadian gold exploration company with 100% ownership of the Eau Claire and Eastmain gold deposits, located in James Bay, Quebec. Eastmain's Quebec project portfolio includes twelve properties covering over 1200 km2 in the Eastmain/Opinaca gold camp. With the objective of increasing total gold resources and adding a new discovery, diamond drill programs are planned for the Eau Claire and Eastmain gold deposits as well as the Eleonore South project in the 2007-2008 season.
