Aura Silver to Commence Drilling at the Higo Blanco Prospect and Expands Program to Include Drill Targets Adjacent to San Jose M
December 20 2010 - 7:30AM
Marketwired
Aura Silver Resources Inc. (TSX VENTURE: AUU) ("Aura Silver" or the
"Company") is pleased to report that after an extensive review of
its geochemical and geophysical data, the next phase of drilling
will commence at the Company's Taviche property in Oaxaca, Mexico
on January 10, 2011. The Company will be targeting the Higo Blanco
prospect with approximately 12 to 15 drill holes, some of which
will focus on deeper structures: to discover the source of current
high grade silver mineralization as well as to determine the extent
to which gold grades increase with depth along the Mezcal vein. The
drill program will extend from the Piedra del Sapo zone in the
northwest to the Mezcal vein and Cerro La Mina zone to the
southeast within the East Taviche concession.
In addition, given recent community approval, we will be
targeting a number of highly prospective zones, in particular the
La Noria prospect on the Company's property within the West Taviche
concession which surrounds the San Jose mine, owned by Fortuna
Silver Mines Inc. (TSX: FVI)
(http://media3.marketwire.com/docs/aura_figure_1.pdf).
Further, the Company reports a continued increase in its joint
ownership in the Taviche joint venture.
Robert Boaz, President and CEO of Aura Silver, recently visited
La Noria and states, "We are excited to commence drilling at La
Noria following our positive results in 2007. The development of
the San Jose mine by Fortuna is clearly visible from La Noria. The
broad community support for this development has given us a new
found confidence for resuming our exploration in this area. We are
also excited to expand the size of our silver and gold discoveries
at Higo Blanco in the East Taviche concession".
La Noria Comes to the Forefront
Exploration will resume at the Company's highly prospective La
Noria prospect located two kilometers west of Fortuna's San Jose
mine and within the West Taviche concession
(http://media3.marketwire.com/docs/aura_figure_2.pdf). The San Jose
mine is currently under development and Fortuna has estimated an
indicated resource of 37,596,000 ounces (150 g/t cutoff) at 435 g/t
equivalent ounces of silver.
The La Noria prospect is permitted for drilling and garners
strong support from the hosting community. It is comprised of two
north-south trending veins, between 250 and 400 meters apart,
connected by several northwest trending "en echelon" style
extensional veins (see Figure 2). The West Noria vein has been
mapped over a distance of about 600 meters and disappears below
overburden both to the north and south. Samples from dumps contain
up to 17.1 g/t gold and 751 g/t silver. Rock chip samples along
strike of the main vein and adjacent "en echelon" veins gave values
from 0.015 to 1.52 g/t gold and 1.4 to 100 g/t silver.
The East Noria vein has been traced for over 1 kilometer and
dips steeply to the east; it is dominated by vein breccia and
silicification up to 20 meters wide. In the southernmost 300 meters
of the vein, rock chip samples contain up to 4 g/t gold and 210 g/t
silver. The main veins widen where they are joined by the "en
echelon" veins. Drilling in 2007 across the East Noria vein (3
holes totaling 722.4 meters) identified a significant mineralized
and altered package that ranges in width from 15.5 meters in the
northern hole (LN04-07) to 126 meters in the south (LN06-07). All
intervals are defined by strong quartz-adularia-pyrite and
quartz-illite-pyrite alteration with widespread intervals of
moderate to strong, multistage quartz-sulphide-adularia veinlets as
well as hydrothermal vein breccias up to 8 meters wide. The
geologic environment seems to be that of a north-trending shear
zone defined by multiple, steeply, east-dipping faults. Gold and
locally, silver values are anomalous across all three zones and
range up to 1.32 g/t gold and 77 g/t silver.
The style of mineralization observed in the East Noria drill
holes is dominated by broad zones of multi-staged
quartz-sulphide-adularia stockwork and, more locally, hydrothermal
breccias. A similar style of broad, diffuse packages of quartz
stockwork has been identified at the San Jose mine but contains
discrete quartz-sulphide-(adularia)-carbonate veins up to several
meters wide. Careful analysis of our data indicates that similar
gold-silver vein deposits may be present along the La Noria vein
system but possibly at greater depths than observed at the San Jose
mine's Trinidad and Bonanza deposits. This may be the result of a
normal fault between the two vein systems with the La Noria side
being displaced downward.
In addition, Aura Silver speculates that the San Jose resource
extends both north and south beyond Fortuna's concession boundaries
and onto the Company's West Taviche concession. Figure 3
(http://media3.marketwire.com/docs/aura_figure_3.pdf), a
generalized longitudinal section (position located on figure 2),
illustrates the potential for the development of an additional
resource north of the San Jose mine on Aura Silver property once
community approval is obtained. Also, as part of examining these
extensions the Company will begin geologic mapping, sampling and
later in 2011, drilling of the Donaji prospect, located along the
southern extension of Fortuna's Bonanza and Trinidad veins.
Update on Taviche Joint Venture Earn-in
Aura Silver is also pleased to report that it has made the
second to last option payment of US$200,000 to Plata Panamericana
SA de CV, a wholly-owned subsidiary of Pan American Silver Corp
(TSX: PAA / NASDAQ:PAAS) as required by the Option Agreement
("Agreement") dated June 8, 2009. Required minimum exploration
expenditures under the Agreement of US$4 million have been achieved
with expenditures to date totaling approximately US$4.3 million. A
final option payment of US$250,000, due on or before September 1,
2011, remains as the final financial obligation to complete the
joint venture earn-in.
Company expenditures to date represent an approximate 42.3%
total interest in the Taviche project. Ongoing expenditures for the
Taviche project continue to be solely funded by Aura Silver and
will increase the Company's interest in the Taviche project toward
the completion of final earn-in.
