New gold target - 254 g/t Au, 640 g/t Ag & (greater than)500 g/t Te High-Grade Eau Claire Drill Assays

TSX Symbol: ER

TORONTO, Sept. 24 /CNW/ - Eastmain Resources Inc. (TSX:ER) is pleased to announce the discovery of a new gold target at its wholly-owned Clearwater project, located in James Bay, Northern Québec. Surface prospecting along favourable deposit stratigraphy this summer led to the discovery of the Boomerang Prospect, where a composite grab sample of vein material, located one-half kilometre east of the Eau Claire gold deposit, assayed 254 g/t Au (7.42 ounces gold per ton), 640 g/t Ag (18.7 ounces silver per ton) and (greater than)500 g/t tellurium (Map 1, website).

Other anomalous samples within the Boomerang Prospect area include 30.6 g/t Au (0.89 ounces gold per ton) and 9.04 g/t Au in key volcanic/sedimentary rocks, located up to eight kilometres east of the deposit. The Boomerang prospect contains a highly enriched gold-tellurium metal signature similar to Eau Claire, which suggests it was derived from the same hydrothermal gold-bearing system. Boomerang will be drill-tested in future programs.

The current drill program is focused on defining a measured, near-surface resource for potential extraction by open pit methods. A total of 7,400 metres of drilling, to test the Main Group of Veins within the central portion of the deposit and the T-Vein series, found north of the previously defined gold resource, has been completed to date. Drilling will continue throughout the quarter.

Significant assay data highlights from the first 8 of 19 drill holes of the current program at Eau Claire (Clearwater project) comprise: 24.81 g/t Au (0.72 ounces per ton) over 2.0 metres, including 69.8 g/t Au (2.04 ounces per ton) over 0.5 metres in hole ER09-198; 10.64 g/t Au (0.31 ounces per ton) over 3.0 metres, including 34.1 g/t Au (1 ounce per ton) over 0.5 metres in hole ER09-203; and 19.75 g/t Au (0.58 ounces per ton) over 2.5 metres in hole ER09-204, including 37.8 g/t Au (1.10 ounces per ton) over 0.5 metres. Fine-grained visible gold, common to the deposit, has been observed in seven of eight drill holes reported herein. Assay data is pending for the remaining 11 drill holes.

Over the past 22 months, a total of 28,600 metres (153 HQ drill holes) has been completed to expand the Eau Claire gold resource within the upper 300 metres. In 142 drill holes, 400 gold-bearing quartz-tourmaline vein intervals with an average grade of 13.1 g/t Au (0.38 ounces per ton), at an average thickness of 1.35 metres, have been intersected within the upper one-third of the deposit (Table 1). 350 vein intervals contain an average grade of 14.9 g/t Au (0.43 ounces per ton); 250 vein intervals averaged 19.6 g/t Au (0.57 ounces per ton); 150 vein intervals contain an average of 27.6 g/t Au (0.80 ounces per ton); 100 vein intervals contain 39.4 g/t Au (1.15 ounces per ton) and 50 intersections have an average of 63 g/t Au (1.84 ounces per ton).

Near-term exploration objectives include continued definition drilling of the high-grade Eau Claire gold deposit, completion of the metallurgical testing program and updating the resource calculation.

    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.
