Eastmain Resources Inc. (ER:TSX) announces that ongoing exploration work at its Éléonore area properties, in joint venture with Goldcorp Inc. (TSX: G, NYSE: GG) and Azimut Exploration Inc. (TSX-Venture: AZM), has uncovered several target zones consisting of altered sulphide-bearing sediments similar to those found on Goldcorp’s neighboring Éléonore property. Roberto-gold-deposit-type host rocks have been identified at both Azimut D and Éléonore South.

Azimut D (Eastmain-Azimut JV Option)
Follow-up prospecting and soil sampling over a number of areas enriched in gold and arsenic, as outlined in 2005 surface programs, have been completed on the Azimut D property. Prospecting over VTEM anomalies has located several zones of disseminated sulphide (pyrite, pyrrhotite and arsenopyrite) within siliceous sediments and paragneiss. Moderately to strongly siliceous, sulphide-bearing paragneiss comparable to that reported recently by Everton Resources Inc. to contain significant gold values (Everton press release Aug.15, 2006) has been detected at Azimut D. Aluminous and siliceous sediments, very similar to altered rocks found within and below the ore zone at Roberto, have also been traced along the flanks of VTEM anomalies in a number of D-Block target areas.

A total of 165 rock samples have been collected over regional VTEM and high-priority, gold-in-soil anomalies. 1535 soil geochemical samples have been collected over a number of target areas where preliminary sampling yielded coincident gold and arsenic values within the 80th percentile or higher. Assay results are pending.

Éléonore South (Eastmain-Goldcorp-Azimut JV Option),
Work at the Éléonore South Project, where Eastmain is project operator, is also underway. More than 400 regional soil geochemical samples have been collected on the Éléonore West Block. Preliminary prospecting and rock sampling of the West Block has identified two regionally continuous sulphide-bearing horizons within a suite of mafic volcanic rocks. Assay results are pending.

Initial mapping of the Main Grid at Éléonore South, over the eastern end of a roughly 15-km-long zone of enriched gold and arsenic within the soils (discovered in 2005), confirms the presence of altered, sulphide-bearing sediments analogous to those hosting the Roberto gold deposit. Finely disseminated sulphides (pyrite, pyrrhotite and arsenopyrite) associated with siliceous and/or strongly potassic altered, fine-grained sediment have been identified in several locations. Andalusite-rich, fine-grained sediments similar to those found immediately below the Roberto gold deposit have also been delineated. In addition, a conglomerate unit recognized as a marker horizon to nearby gold deposition at Roberto, has been located by Eastmain geologists on the Éléonore South property. Locally, fine grained sulphide-bearing sediments appear to grade to siliceous sulphide-rich paragneiss comparable to gold-bearing units described at Everton’s Wildcat property.

To date a total of over 4500 soil samples have been collected at Éléonore South. Assays are pending. Sampling, mapping, prospecting and rock sampling are ongoing in an effort to delineate target zones for future trenching and drilling.

Airborne VTEM surveys have been very successful in delineating sulphide targets. Eastmain has contracted the services of Geotech Ltd. of Aurora, Ontario to fly approximately 800 line-kilometres of VTEM at Éléonore South during the current field season.

Surface work is being carried out by personnel of Eastmain Resources Inc., J.A. Macleod Exploration Reg’d and Norman McBride Exploration under the supervision of Dr. Vincent Jordain, P. Eng. and qualified person. This meets the standards for exploration and development for mining properties according to National Instrument 43-101 and Companion Policy 43-101CP.

Eastmain Resources Inc. is currently in its second year of five-year agreement with Azimut Exploration Inc., whereby Eastmain has the option to earn an initial 50% interest in the Azimut D Block for a total cash payment of $140,000 and work expenditures of $1.9 million over five years. Eastmain has the right to increase its ownership to 65% interest upon bankable feasibility (Eastmain News Release March 30, 2005). Eastmain is the project operator.

On April 27, 2006 Eastmain, Goldcorp and Azimut announced a letter of intent to form a three-way joint venture on the Éléonore South property. Eastmain has the option to earn a one-third interest in the project by funding $4 million in exploration over four years and can increase its ownership to 40% by completing a bankable feasibility study. Eastmain is the project operator.

Eastmain is a Canadian exploration Company holding several early-to advanced-stage gold and base metal projects in Canada. Eastmain's project portfolio includes twelve properties in the Eastmain/Opinaca gold camp, where Goldcorp recently purchased the Éléonore Project.
