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 of Yan
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 of Martin 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.
