TORONTO, Nov. 12 /PRNewswire-FirstCall/ - Eastmain Resources Inc. (TSX:ER) is pleased to announce assay data from continued definition drilling at its Eau Claire Gold Deposit, located in James Bay, Quebec. 46 holes totaling 13,765 metres have been completed to date during this phase of drilling. Holes 205 through 214 intersected 33 gold-bearing quartz-tourmaline veins. Each of these holes intersected gold-enriched veins; nine with high-grade assays. Significant assay highlights for holes 205 through 214 include multiple vein intersections containing over half an ounce of gold, adding to an overall increase in the grade and size of the deposit (Table 1).

ER09-208 intersected 12.92 g/t Au over 1.0 metre, including 25.8 grams per ton (g/t) gold (Au) or 0.75 ounces per ton (oz/ton) over 0.5 metres, and 7.07 g/t Au over 1.5 metres, which included a half-metre sample of 18.3 g/t Au or 0.53 oz/ton. Up to 7.05 g/t Au over 2.5 metres, including 26.1 g/t Au (0.76 oz/ton) over a half-metre, was reported in hole ER09-209. A composite sample averaging 9.88 g/t Au along 1.5 metres, which included 29.10 g/t Au (0.85 oz/ton) over 0.5 metres, and a half-metre sample assaying 42.1 g/t Au or 1.23 oz/ton were reported in ER09-210. Hole ER09-211 intersected a metre-wide vein grading 14.17 g/t Au, which included a half-metre interval of 28.0 g/t Au (0.82 oz/ton); 8.59 g/t Au over 2.60 metres containing 18.95 g/t or 0.55 oz/ton gold over a half-metre; and a half-metre interval of 35.0 g/t Au (1.02 oz/ton) within a metre-wide intersection averaging 27.03 g/t Au. Hole ER09-212 intersected 8.78 g/t Au over 1.5 metres to include 18.05 g/t Au (0.53 oz/ton) over 0.5 metres. A half-metre sample interval in ER09-214 assayed 21.6 g/t Au (0.63 oz/ton) within a metre-wide vein averaging 10.83 g/t Au.

Fine-grained visible gold, common throughout the deposit, was observed in seven of ten drill holes reported herein. Assay data is pending for an additional 29 holes, in which at least 25 vein intersections contain from one to more than 50 grains of visible gold. The current program will be completed with another 1,000 metres of drilling this month (Map 1, website).

Over the past 24 months, a total of 35,700 metres (181 HQ drill holes) has been completed to expand the Eau Claire gold resource within the upper 300 metres. The average grade of the Eau Claire deposit is increasing. Over one-quarter (28%) of all gold intercepts drilled within this period contain over one ounce of gold per ton. 72% of all gold-enriched vein and schist material intersected within Eau Claire exceed one-half (0.50) ounces per ton of gold over an average thickness of 1.30 metres.

In 152 drill holes, 433 gold-bearing quartz-tourmaline vein intervals with an average grade of 12.5 g/t Au (0.37 oz/ton), at an average thickness of 1.35 metres, have been intersected within the upper one-third of the deposit. 350 vein intervals contain an average grade of 15.3 g/t Au (0.45 oz/ton); 250 vein intervals averaged 19.6 g/t Au (0.57 oz/ton); 150 vein intervals contain an average of 28.2 g/t Au or 0.82 oz/ton; 100 vein intervals contain 39.7 g/t Au (1.16 oz/ton) and 50 intersections have an average of 64.2 g/t Au or 1.88 oz/ton (Table 2).

Near-term exploration objectives are to define a measured gold resource and expand the upper third of the Eau Claire gold deposit. Upon completion of this phase of drilling approximately 500 gold-bearing vein intersections will have been added to the previous indicated resource estimate (December 2005).The swarm of veins found north of the previously defined gold resource (T Veins) has the potential to double the size of the deposit.

Previous drilling and recent prospecting have also outlined high-grade, gold-bearing veins east (Boomerang Prospect) and west (850 West Zone) of the Eau Claire gold deposit, which will be drilled during the next phase. Numerous rock and soil anomalies enriched in gold and tellurium identified along the favourable deposit horizon for several kilometres will also be trenched and drilled in 2010.

    Chemical analysis was completed by ALS CHEMEX Laboratories using a 50-
    gram split and gravimetric techniques. The visible gold samples were
    mechanically screened and assayed for metallics. Internal standards
    provided by an independent company and blank samples were inserted for
    quality control purposes. Assay samples are taken from HQ core, sawed in
    half with one half sent to a commercial laboratory and the other half
    retained for future reference.
    -------------------------------------------------------------------------
    Note: Sample length approximates true thickness. VQTL VG =
    Quartz-tourmaline vein with visible gold. VG5+ = five grains
    of visible gold were identified in the sample. TE = visible
    grains of tellurides.
