Clearwater Project
Exploration drill results, Infill
& Composite Assays
Eastmain Resources Inc. (TSX:ER) announces exploration drill results from the Boomerang, SNL and
850 West Zones at its Clearwater Project, James Bay, Quebec (see
website for Table 1). Gold-bearing, quartz-tourmaline veins and
alteration zones have been intersected in each of the three areas, well
outside of current limits of the Eau
Claire deposit. On-going infill drill core sampling has also detected
wide zones of gold mineralization in previously drilled holes. Hole
ER07-98, which formerly assayed 37.2 g/t Au across a half-metre interval, returned up to 8.19 grams gold per tonne over 5.0 metres.
Composite intervals for 64 drill holes completed within the 450 West
Zone report up to 39.6
grams gold per tonne across 36.7 metres (ER07-98). This work
demonstrates that in addition to its high-grade gold-vein system, Eau
has open-pit, bulk-tonnage potential.
Boomerang and SNL Target Areas
Gold-bearing, quartz-tourmaline veins and
wide-alteration zones have been intersected up to 2.5 km east of the
Eau Claire gold deposit. In the Boomerang Lake area, located about 500 metres east of Eau Claire, drill holes ER10-249,
254 and 256 intersected a gold-bearing vein system over a lateral
distance of 200 metres. These veins are
coincident with gold-rich veins delineated in trench CW2010-15, which
assayed up to 19.40 g/t gold and 15.95 g/t tellurium (Oct 6, 2010 news
release) and earlier trenching, which assayed up to 25.0 g/t Au. Drill
holes ER10-257 to 260 intersected gold-bearing quartz-tourmaline veins
within the SNL target area, located two kilometres
east of Eau Claire, where earlier
trenching reported up to 10.0 g/t gold. Further east, drill holes
ER10-261, 262, 265, and 275 define a set of quartz-tourmaline veins
over a strike-length of 225 metres. Assays
from this zone include 0.23 g/t Au over 43.7 metres
and 14.75 g/t Au over 0.5 metres. Still
further east within the SNL target area, holes ER10-271 and 273
intersected wide zones of alteration and gold-bearing,
quartz-tourmaline veins while hole ER10-269
intersected gold veining coincident with surface grab samples taken in
2010, which assayed up to 41.50 g/t Au and 23.10 g/t Te.
Additional drilling is recommended within the
Boomerang and SNL target areas to search for a swarm of high-grade
veins similar to those found at Eau Claire and for wide "bulk
tonnage" type mineralization.
850 West Zone
Drilling at the 850 West Zone detected both
high-grade and wide lower-grade zones of gold-bearing rock near
surface. Assays range from 0.86 g/t Au over 11.0 metres
to 3.14 g/t Au over 12.0 metres to 50.20 g/t
over a half-metre. ER10-268 intersected 6.97 g/t gold and 13.17 g/t
tellurium over 5.0 metres,
including up to 36.2
g/t Au and 35.3 g/t Te over 0.5 metre,
in Vein 16. ER10-270 also intersected 6.47 g/t Au over 6.7 metres,
including intervals containing 18.95 g/t Au and 10.05 g/t Te, over 2..0
metres, and up to 50.2 g/t Au and 22.5 g/t Te
across half-a-metre in Vein 16. Assays are
pending for several drill holes, which also intersected the same
gold-bearing structures.
The 850 West Zone occurs on a topographic
high, as does the 450 West Zone, and is open laterally to the
northeast, southwest and at depth. Previous surface stripping and
trenching of the 850 West Zone exposed a series of gold-rich veins. The
average gold grade from one-metre-wide
channel samples taken every five metres along
a length of 22 metres for Vein 12 is 118.0
g/t. Vein 16, also located within the 850 West Zone, has a average
grade of 21.3 g/t gold over a length of 67 metres
and a width of one metre.
2011 exploration will continue with definition
drilling this area.
450 West Zone Composite Intervals
Composite intervals, which average 3.0 grams
gold per tonne across an average thickness of
28.0 metres, are reported for 64 drill holes
(Table 1), completed within the Main
Group of Veins (P, JQ, R & S). These composite intervals are centred on the 450 West Zone and extend over a
strike length of more than 230 metres.
Exceptional intervals include: 4.88
g/t Au over 27.5 metres in
ER07-85; 8.55
g/t Au over 36.7 metres in
ER07-87; 24.62
g/t Au over 55.6 metres in
ER07-98 and 6.75
g/t Au over 34.8 metres in
ER07-104.
Wide zones of anomalous gold have also been
delineated within the footwall T Veins at Eau Claire. Results from this
zone include: 2.82 g/t Au over 44.9 metres in
ER09-132; 3.32 g/t Au over 27.6 metres in
ER09-136 and 1.54 g/t Au over 69.8 metres in
hole ER09-145. Drill spacing within the footwall T-Vein swarm is
broader and additional drilling required to delimit these structures is
planned for 2011. Broad intervals of anomalous gold, outlined both
within the Main Group of Veins and the footwall swarm, support a
bulk-tonnage, open-pit potential for the upper portion of the Eau
Claire deposit. Early drilling results from the 850 West Zone indicate
there is potential for additional open pit resources in that vicinity
as well..
2011 Exploration Program
The Corporation has allocated a $5-million
exploration program for Clearwater, which will include 25,000 metres of drilling focused on further defining the
850 West Zone and the Eau Claire gold deposit vertically at depth
between 200 and 500 metres. The objectives of
the program are to expand the global gold resources and to upgrade
resource categories.
