Marban
Eastern Down Dip Zone Returns 6.4 Grams per Tonne of Gold over 8.9 metres
Aurizon
Mines Ltd. (TSX:ARZ)(NYSE Amex:AZK) is pleased to announce initial drill
results from the second phase program at the Marban property, located in the Malartic
gold camp, Abitibi region of Quebec.
Results
from 15 new drill holes completed on the Marban gold deposit are included in
this release. Drill results are tabled on the following pages.
Drilling
highlights include:
-- Hole MB-12-272, drilled on section 4550E, at the eastern end of the
Marban deposit, returned four important gold mineralised intervals as
follows:
-- 2.4 g/t over 19.2 metres at a vertical depth of 235 metres,
including 5.6 g/t Au over 7.2 metres
-- 3.0 g/t Au over 14.4 metres at a vertical depth of 260 metres
-- 7.6 g/t Au over 5.0 metres at a vertical depth of 360 metres
-- 6.4 g/t Au over 8.9 metres at a vertical depth of 380 metres
-- The two deepest mineralised intervals of hole MB-12-272 are located 90
to 110 metres above the mineralised intersection in hole MB-11-242
within the newly recognised Eastern Down Dip Zone, which averaged 6.1
g/t Au over 12.6 metres.
-- The new results emphasise the potential to identify additional mineral
resources within the Eastern Down Dip Zone between a vertical depth of
-350 and -600 metres. The mineralised structure is considered open
laterally to the east and at depth.
-- The first two mineralised intervals of hole MB-12-272 were obtained at
the eastern limit and just below the stopes of the former Marban mine.
Three new intersections were also obtained in proximity to hole MB-12-
272, as follows:
-- 1.3 g/t Au over 26.2 metres (MB-12-251)
-- 32.1 g/t Au over 1.0 metre (MB-12-256)
-- 20.5 g/t Au over 1.1 metres (MB-12-257)
The
second phase program will include a total of 34,000 metres of diamond drilling,
an updated mineral resource estimate and basic technical studies, including
metallurgical testwork. Drilling commenced on December 13, 2011,
and four drill rigs are currently in operation to expand the mineral resources
of the Marban deposit. To date, thirty-six (36) holes and seven (7) extensions
of previous holes have been completed for a total of 14,430 metres. The second
phase program and an updated mineral resource estimate are expected to be
completed by the end of the second quarter of 2012.
Marban
deposit drilling
The
2011 first phase drill program demonstrated the continuity of the
mineralization between surface and minus 250 metres, as well as the grade
consistency, and lead to the discovery of the Western High Grade Zone. This
first phase also identified the Eastern Down Dip Extension Zone which is
located below 250 metres and remains open at depth and laterally.
Objectives
of the 2012 second phase drilling program are:
1. Improving quality and potential of the near surface resources:
The objective is to improve the quality of the known resources and to
increase the potential to find more mineralised corridors within a pit
shell to help decrease the stripping ratio, and will include drilling
the Western High Grade Zone.
2. Developing a mineral inventory below a vertical depth of -250 metres:
This objective targets the identification of new mineral resources
inside the Marban structural zone. Preliminary interpolation on the
Eastern Down Dip Zone indicates a strong potential to identify mineral
resources between a vertical depth of -350 and -600 metres. The
mineralised structure is considered open laterally and downdip.
New holes and the extension of previous holes are planned at vertical
depths of -300 metres to -1,000 metres to test the consistency and
extension of the Eastern Down Dip Zone at an average drill hole spacing
of 50 metres.
Aurizon
Option
Aurizon
can earn up to a 65% interest in the Marban property under the terms of an
option and joint venture agreement dated July 5, 2010 between
NioGold and Aurizon (see news release dated July 6, 2010). The
initial 50% interest can be earned by incurring expenditures of $20
million over three years, completing an updated NI 43-101 compliant
mineral resource estimate, and by making a resource payment for 50% of the
total gold ounces defined by the mineral resource estimate. NioGold remains the
project operator during the initial earn-in period.
The
first phase program commenced on August 30, 2010, and was
completed on August 9, 2011. The program consisted of 50,253
metres of diamond drilling (170 holes, 8 extensions) at a total cost of $6
million. Drilling was distributed between the Marban (41,270 metres)
and Norlartic (4,319 metres) deposits and exploration drill hole fences between
the two deposits (4,664 metres). The Norlartic deposit, historically mined from
underground is located 1.2 kilometres westward along the same shear zone
system. Highlights include the identification of two new gold zones surrounding
the former Marban mine named the High Grade Western Zone and Eastern Down Dip
Zone.

Technical
Info, QA/QC and Qualified Persons
Reported
intervals are in core lengths but are anticipated to approximate true width,
except where structural complexities occur, as the holes were drilled near
perpendicular to the principal local structural orientation.
Diamond
drill holes were drilled with NQ-size core in order to obtain larger sample
volumes of the mineralised zones, except for holes that traversed underground
workings which were completed using BQ-size core. The core was sealed and
delivered by the drilling contractor to NioGold's facilities located at the
Norlartic mine site. The core was photographed for reference, logged and
mineralised sections were sawed in half. Sample lengths vary between 0.5 to 1.5
metres. Half core samples were bagged, sealed and delivered to ALS Chemex
in Val-d'Or, Quebec,
an accredited laboratory. The remaining core is stored on site for reference.
Samples were assayed by the fire-assay method using an atomic absorption finish
on a 50-gram pulp split. A quality assurance and quality control program
(QA/QC) was implemented by NioGold and the laboratory to insure the precision
and reproducibility of the analytical method and results. The QA/QC program
includes the insertion of standards, blanks and field duplicates in the sample
batches sent to the laboratory and a systematic
re-assaying of samples returning values above 2 g/t Au by the fire-assay method
using a gravimetric finish. As well, pulps grading above 0.5 g/t Au are sent to
Bourlamaque Assay Laboratories Ltd. in Val-d'Or
for check assaying.
The
drilling program was conducted under the supervision ofYan Ducharme,
M.Sc., P.Geo. (OGQ), Niogold's Exploration Manager, a qualified Person as
defined by National Instrument 43-101. This news release was prepared under the
supervision ofMartin Demers, P.Geo., Exploration Manager of
Aurizon and a Qualified Person under National Instrument 43-101, based on
information made available by Niogold and verified by personnel of Aurizon.
