Aurvista Gold Corporation (TSX VENTURE:AVA) is pleased to announce
the results of a significant gold intercept in a drill hole on its
wholly-owned Douay project ("the Property"), located in the
Matagami region, Quebec. Drill hole DO-11-61, which was testing the
eastern extension on the "Zone 10" gold deposit as part of the
"Phase 1" drill program focussed on expanding existing resources on
the property, returned a high grade intercept of 8.4 g/t Au over
6.8m true width. The "Zone 10" gold deposit is located 1 km east of
the "Central Zone" and 600 m west of the "531 Zone", that host
respectively (at a cut-off of 0.7 g/t Au) an Inferred Resource of
6.74 Mt at 0.97 g/t gold (211,000 oz.) and 5.44 Mt at 2.15 g/t gold
(376,000 oz) (source.: SGS 43-101 Technical Report for Aurvista,
dated March 15, 2011).
The results of the drill hole DO-11-61 intercept are presented
in the table below:
----------------------------------------------------------------------------
Drill Hole # From To Core length True width Grade
(m) (m) (m) (m) Au (g/t)
----------------------------------------------------------------------------
DO-11-61 82.0 110.0 28.0 15.9 4.1
----------------------------------------------------------------------------
incl. 98.0 110.0 12.0 6.8 8.4
----------------------------------------------------------------------------
incl. 102.0 107.0 5.0 2.8 14.1
----------------------------------------------------------------------------
The mineralization at the "Zone 10" deposit occurs at the
near-contact between siltstones and basaltic volcanics. A recent
interpretation of the "Zone 10" deposit suggests that the
mineralized zone is nearly vertical along an east-west-oriented
shear zone.
The "Zone 10" deposit currently hosts an Inferred Resource of
1.0 Mt at 2.04 g/t gold (66,000 oz.) with an additional Measured
and Indicated Resource of 31,000 t at 2.3 g/t gold (2,000 oz.), at
a cut-off of 0.7 g/t gold. The shallow (65 metres vertical) high
grade results obtained from hole DO-11-61, drilled 20 metres to the
east from the eastern-most previous hole of the "Zone 10" deposit,
stand out from historical gold results on this zone in terms of
grade and thickness. Moreover, this new drill intercept opens the
exploration potential to increase the gold resource towards the
east that still remains untested to date over a strike length of
600m and at depth.
Guy Brunet, Aurvista's CEO stated "we are really pleased that
these results indicate the prolific ability of the Douay Property
to generate additional gold mineralization that could ultimately be
either incorporated into a bulk tonnage target or as stand-alone
high-grade satellites". The "Phase 1" drilling program on the Douay
property was recently completed on selected targets along the
contact between volcanic and sedimentary rocks that is believed to
be associated with a "pull-apart basin" (the "Pull-apart" Zone)
geological setting, where significant historical gold values were
intersected. Other follow-up drill holes were also performed in the
extensions of the "Zone 10" deposit and the "Central Zone". Results
from these holes are still pending and will be released when
available. All data are being compiled and the targeting process is
well underway for the follow-up drilling phase slated to begin in
early January 2012 on the Property. Drill holes planned for 2012
will focus on extending the known gold resources in the bulk
tonnage "porphyry " deposits on the Douay Property in both the
inferred and indicated categories (currently covering an area of
approximately 2 km in strike length) to the west, to the east and
to depth (up to depths of 450 m), as well as on extending known
resources on other targets on the property, including Zone 10 and
other targets and showings on the 12 km NE trending regional
"Pull-apart" structure representing the volcanic/sedimentary
boundary.
In addition, as described in Aurvista's press release of
September 21, 2011, in conjunction with an external consultant,
Aurvista is continuing to work on creating a 3-D model of the
mineralization at the "Porphyry Zone" (comprising the Adam 92-7
zone and the "Central Zone" described above, and located within
1000 m of "Zone 10"). The outcome of the modelling, including
investigation of lower cut-off grades than those used in past
resource calculations, will be integrated with the geological
interpretation to investigate the potential of the "Porphyry Zone"
as a low-grade open pit style deposit, as well as the additional
potential of other zones on the property such as "Zone 10".
Aurvista implements an Analytical Quality Assurance Program to
control the analytical quality of assays in its exploration work.
This program includes the systematic addition of blank samples and
certified standards to each batch of samples sent for analysis at
commercial laboratories. Blank samples are used to check for
possible contamination in laboratories while certified standards
determine the analytical accuracy and precision. Samples have been
assayed at the Laboratoire Expert Inc. in Rouyn-Noranda and at ALS
Chemex Inc. in Val-d'Or. Samples are assayed by fire-assay (30g)
followed by atomic absorption according to industry standards.
Repeats are completed by fire-assay followed by gravimetry on
selected samples.
