Aura Silver Confirms High-Grade Copper Drill Target Greyhound Project, Nu

Marketwired
Aura Silver Resources Inc. (TSX VENTURE: AUU)("Aura Silver" or the
"Company") is pleased to report that recent data acquired in late
2010 from surface and soil sampling surveys, in combination with
earlier airborne MEGATEM geophysical survey results, has delineated
a possible source for the high grade copper-zinc float samples
grading 9.2% copper and 18.5% zinc found 850 meters northeast of
Aura Lake on its Greyhound property approximately 41 kilometers
north of Baker Lake, Nunavut.
The initial discovery of high grade base metal-bearing angular
float boulders led to an interpretation that these may have been
derived from the volcanic rocks to the southwest. Subsequent
drilling in 2010 revealed a much more complex structure in this
area, with a predominance of graphitic argillite in what appears to
be a fault-bounded block. This argillite sequence proved to be the
cause of the numerous VTEM geophysical anomalies under Aura Lake.
Additional mapping uncovered a previously unknown 2 kilometer long
N-S trending unit of felsic volcanic strata about 1.7 kilometers
northeast of the base metal discovery. The felsic volcanic rocks
are profoundly sodium (Na) depleted for about 400 meters along
strike; Na depletion is a key indicator of proximity to
volcanogenic massive sulfide (VMS) deposits. Dr. J. Franklin, Aura
Silver's Chief Scientist states, "Highly sodium depleted and
copper-zinc enriched felsic volcanic rocks (which contain less than
0.5 % Na2O) likely indicate the proximity to a volcanogenic massive
sulfide system". While not defining a drill target, the
lithogeochemical results point to a broad area of highly
hydrothermally altered felsic rocks, a locus for potential
copper-zinc deposition.
The soil geochemical contents further refine the target area by
defining a 600 meter-long copper-zinc anomaly (up to 323 ppm Cu and
up to 185 ppm Zn) encompassing an area west of the Na depleted
rocks. The soil samples in the area underlain by anomalous base
metals are also depleted in Na. This soil anomaly is adjacent to
two distinct MEGATEM anomalies which are located under an unnamed
lake and will be a prime target for additional ground geophysics
surveying and drilling as part of the 2011 exploration program on
the Greyhound property.
Robert Boaz, CEO of Aura Silver stated, "Our prime focus at
Greyhound will remain the defined gold and silver targets around
Aura Lake to the south-west of the property as well as the newly
discovered Meadowbank-like prospect to the north-east (see Press
Release #10-27, November 24, 2010). However our geologists have
been intrigued by the high copper-zinc values since they were found
in 2008. We have confirmed through our soil sampling program that
there is a high potential for discovery of buried base metal
mineralization within the vicinity of Aura Lake. In addition to
drilling for precious metals in the spring of 2011 a concerted
effort will be directed toward the high value copper target."
The Company's Greyhound property comprises 25,333 hectares
located approximately 38 kilometers north of the community of Baker
Lake. Infrastructure is excellent. An all-weather road from Baker
Lake to the Meadowbank Mine crosses through the Greyhound property
and is located less than one kilometer from this high grade
copper-zinc discovery.
Dr. James M. Franklin, P. Geo. is Aura Silver's qualified person
(as defined by National Instrument 43-101) and has reviewed and
approved the scientific and technical information in this press
release.
