Eastmain Mines Inc., a wholley-owned subsidiary of Eastmain
Resources Inc.(TSX:ER), announces
assay results from drilling at the Eastmain Gold Deposit, which is
located at the eastern end of the Eastmain River Greenstone Belt, in
James Bay Quebec. Drill hole EM10-28 intersected a 9.5-metre-wide
zone of gold-silver-copper mineralization grading 12.2 g/t gold
within the B Zone Mine horizon rocks. This intersection, which occurs
from 217.5 to 227.0 metres down the hole, includes 17.4 g/t gold
over 5.0 metres and 24.1 g/t gold plus 30.1 g/t silver over 2.5
metres.
A 14,000-metre
drill program is currently being completed at the Eastmain Mine
project. Objectives of the 2010 drilling are to expand both the lateral
and vertical limits of the known A, B and C Zones of the Eastmain Gold
Deposit, define the structural and lithological controls of gold
mineralization, and to drill-test a number of regional geophysical and
geochemical targets elsewhere on the property.
The A, B and C
zones of the deposit have a large mineralized "footprint"
occurring over a length of 1.7 kilometres. Prospecting has also
identified significant copper-gold mineralization extending for several
kilometres northwest of the A Zone, with grab samples grading from 1.38
to 33.3 g/t Au.

Notes:

The mineralized interval consists of altered
Felsic tuff with quartz veins, accessory pyrrhotite, chalcopyrite and
pyrite. Visible gold was observed in the interval from 223.0 to 225.5
metres.

Drill hole EM10-45, located over a kilometre southeast
of hole EM10-28, intersected three mineralized horizons within the C
Zone in similarly altered "Mine Series" rocks as those
defining the A and B Zones. Hole 45 intersected 4.3 metres of
altered, visible-gold-bearing, mineralized (pyrrhotite and
chalcopyrite) basalt and rhyolite tuff cut by quartz veining in the
upper part of the hole from 128.4 to 132.7 metres. This unit is
followed by a 2.7-metre-wide mineralized zone from 143.4 to 146.1
metres down the hole, consisting of altered rhyolite tuff with quartz
veining, one grain of visible gold and minor pyrrhotite and pyrite. In
turn, this zone is proceeded by an 8.0-metre-wide interval of the main
mine series rocks from 220.0 to 228.0 metres depth, composed of highly
altered ultramafic rocks and rhyolite tuff with layers of massive
pyrrhotite and chalcopyrite.. Assay results for this hole and several
others are pending.
Dr. Donald J.. Robinson, President and CEO of Eastmain
stated, "Although assays for a substantial number of drill
holes are currently pending, we are impressed with the first
phase of drilling at the Eastmain Mine property. Drilling has
intersected a number of mineralized intervals of significant
thicknesses in all three zones of the Eastmain Gold Deposit. Surface
exploration has also confirmed the potential for additional discoveries
along the mine trend."
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 for the drilling was completed by
ALS CHEMEX Laboratories using a 50-gram split for multi-element and
gold ICP analysis. Samples grading over 500 ppb are analyzed by fire
assay techniques with and atomic absorption finish. Samples greater
than 10 grams are then fire-assayed with a gravimetric finish. Internal
standards provided by an independent company and blank samples were
inserted for quality control purposes. Assay samples are taken from NQ
core, sawed in half along the core axis; one half is sent to ALS
Laboratories and the other half retained for future reference.
