More 850 West & Gap Zone Drill Assays
RC Trench "Soccer Field" 16.4 g/t Gold across 13.5 m
TORONTO, ONTARIO--(Marketwire - Feb. 9, 2012) - Eastmain Resources Inc. (TSX:ER) is pleased to announce drilling and trenching results from its wholly-owned Clearwater Project, located in James Bay Québec. 2011 drilling focused on testing the 850 West and Gap Zones, located immediately west of the Eau Claire Gold Deposit. 68 drill holes were completed at 25- to 50-metre intervals over an area 550 metres long by approximately 300 metres wide, and to a vertical depth of more than 300 metres. Assay highlights are reported for 51 drill holes and five trenches (Tables 1 and 2). Visible gold has been observed in 25 drill holes and from the Rebecca Collins (RC) "Soccer Field" trench. Numerous screen-metallic check assays on samples containing visible gold have increased the grade of several of these intervals. Additional assay data is pending.
The 2011 drill program has confirmed a stacked series of gold-bearing, quartz-tourmaline veins, ranging from 0.5 to 25.5 metres in thickness, within the 850 West and Gap Zones. Veins range in grade from 0.50 to 60.5 g/t Au and up to 88.75 g/t Te, with an average grade of 6.50 g/t Au over 6.09 metres (Table 1). These drill intersections, which are located outside the limits of the previous resource estimate, are expected to have a positive impact on expanding total gold resources at the Eau Claire gold deposit.
A 40,000-metre, $7M drill program has been approved for the Clearwater Project. The top priority will be to expand and define gold resources amenable to open pit extraction. Prospecting, trenching and drilling will continue along the key horizon, extending laterally in both directions from the Eau Claire deposit.
Trenching & Prospecting
Channel sample data from the RC Soccer Field Trench, located on the south face of the 850 West Zone ridge, has confirmed very high grade gold assays from seven different intervals (Table 2; see website for plan map). Abundant visible gold was reported from this target area. Several continuous high grade intervals include: Channel RC-2, grading 8.0 g/t Au across 4.50 metres; channel RC-3, which contains 16.4 g/t Au over 13.5 metres, including 24.0 g/t Au over 8.5 metres and 268.0 g/t Au over a half-metre interval; and channel RC-6 with values of up to 8.4 g/t Au over 7.5 metres, including 13.3 g/t Au over 3.5 metres. The RC Soccer Field trench corresponds with the surface projection of Vein 10.
Regional prospecting has also located high-grade gold samples within the following target areas - the Pascal, Castor, Boomerang and Knight mineral occurrences. As previously reported, up to 66.5 g/t Au was discovered in quartz-tourmaline veins at the Pascal showing, 500 metres west of the 850 West Zone. Rock samples taken in the Castor area, located immediately south and east of the 450 West Zone, assayed 10.15, 13.0 and 30.5 g/t Au with accessory tellurium (Table 2). Recent channel sampling (2011) from the Boomerang area confirmed high-grade gold at trench CW15, where mineral values range from 6.89 to 17.4 g/t Au and 6.84 to 20.5 g/t Te, within quartz-tourmaline veins located one kilometre east of Eau Claire. Two rock samples taken this year from the Knight prospect, located 15 kilometres east of Eau Claire, assayed 13.2 and 17.4 g/t Au (Table 2, see website for map).
Regional exploration to date on the property has defined several high-priority, drill-ready targets, located well outside the limits of the Eau Claire gold deposit. Historical and current prospecting and trenching are responsible for the discovery of a number of significant regional mineral occurrences on the property, which have not yet been drill tested, including: Pascal, Natel, Vanna, Serendipity and Knight. Additional trenching and definition drilling will continue in 2012 to evaluate these target areas and to test the resource potential of the RC Soccer Field Trench (see website for maps and photos).
Dr. Donald J. Robinson P.Geo, is the Qualified Person for the information contained in this press release and is a Qualified Person within the meaning of National Instrument 43-101. Chemical analysis was completed by ALS CHEMEX Laboratories using a 50-gram split and gravimetric techniques. Screen metallic samples are screened to 100 microns. 50-gram splits are then fire- assayed using an AAS finish. 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 along the core axis with one-half sent to ALS and the other half retained for future reference. Unless otherwise indicated, sample length approximates true thickness.
