TORONTO, ONTARIO--(Marketwire - Sept. 6, 2011) - Eastmain Resources Inc. (News - Market indicators) is pleased to announce that drilling and trenching at its wholly-owned Clearwater Project, located in James Bay Québec, continues to significantly expand the Eau Claire gold deposit. Recent drilling has intersected multiple quartz-tourmaline veins within the Gap Zone, including two new vein sets, the "Mat-Sky" and "Stephanie", each containing visible gold. Assay data from hole 298 and 303 has also confirmed wide, high-grade gold intervals from Vein 12, located within the 850 West Zone, 500 metres west of Eau Claire.
Trenching has delineated the "Conrad Zone" and the "Valli Veins", both consisting of multiple sets of quartz-tourmaline veins, located well outside the limits of the Eau Claire gold deposit (see website for maps and photos).
850 West Zone
Drilling at the 850 West Zone has intersected multiple gold-bearing veins over a strike-length of 300 metres at shallow depths. Visible gold, previously reported (NR AUG 11, 2011) in 10 drill holes which intersect Vein 12, and within the newly discovered Sophie Vein, occurs throughout the 850 West Zone target area. Assay data from holes 298 and 303, re-confirms high-grade gold and tellurium values within the 850 West Zone.

Assays are pending for several exceptional drill intervals, which also intersect the same gold-bearing structures, and contain abundant visible gold within Vein 12 and the Sophie Vein.
Gap Zone
Five drill holes (309, 313, 314, 316 and 319) completed to date within the Gap Zone have intersected multiple quartz-tourmaline veins north of the 850 and 450 West Zones. Two new veins have also recently been discovered in this region. The Mat-Sky Vein is situated near surface, while the Stephanie Vein occurs at depth. Hole 314 intersected the Mat-Sky Vein, a 5.2-metre-wide quartz-tourmaline interval containing 2 grains of visible gold at a depth of 22.8 metres. The Stephanie Vein was intersected in four holes and includes a 2.5-metre-wide interval, at a depth of 266.7 metres, containing 33 grains of visible gold, ranging in size from 0.1 to 0.5 mm. Drill hole 314 intersected the Stephanie Vein across 3.5 metres at a depth of 293.2 metres. Here the Stephanie Vein contains more than 30 grains of visible gold, ranging in size from 0.1 to 1.0 mm, and multiple grains of fine-grained tellurides.
Conrad Zone
Recent trenching 200 metres northeast of the 450 West Zone discovered the "Conrad Zone", a stacked set of 12 parallel, quartz-tourmaline laminated veins and massive replacement zones across a 15 metre-wide interval. These veins are aligned parallel to the Main Group of Veins in the 450 West Zone. The Conrad Zone may represent the surface expression of the T Veins, previously intersected in drilling at Eau Claire. This new discovery area is currently being sampled, (see photos on website).
Valli Veins
Trenching has also discovered the Valli Veins, a set of parallel quartz-tourmaline laminated veins, located 400 metres south of the 450 Zone. Like the Conrad Zone, these newly discovered veins have also been exposed in an area which had no previous drilling or trenching (see website for photos and location).
35 drill holes have been completed at Clearwater in 2011, totaling 12,250 metres of a proposed 25,000-metre program. Trenching has also generated a number of high-priority vein targets peripheral to the Eau Claire deposit, which will be channel sampled and subsequently drilled.
According to Dr. Robinson, President and CEO of Eastmain, "Our 2011 exploration program has been very successful in expanding the Eau Claire deposit. Multiple, high-grade, gold-bearing quartz-tourmaline veins and alteration zones have been discovered outside the previous limits of gold mineralization, as defined by the last resource estimate. Two drill rigs are currently focused on expanding the 850 Zone to the west, and the Gap Zone to the northeast." Robinson continues, "Drill assay data has confirmed wide, high-grade gold intervals within the 850 West Zone, which significantly enhance the open pit resource potential at Clearwater. Recent trenching has also been extremely encouraging, with impressive new vein discoveries located both north and south of the Eau Claire Deposit."
