New gold target – 254 g/t Au, 640 g/t Ag & >500 g/t Te
High-Grade Eau Claire Drill Assays
September 24, 2009
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 >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 goldbearing 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.
