NioGold and Aurizon Report 20.44 G/T AU Over 3.2 Metres at Marban

VAL-D'OR, QC--(Marketwire - December 7, 2010) - NioGold Mining Corporation (TSX-V: NOX) ("NioGold") and Aurizon Mines Ltd. ("Aurizon") are pleased to announce results from drill holes MB-10-108 and MB-10-109 at the Marban Block property, located in the Malartic gold camp, Abitibi region of Quebec. Assays results for these holes were pending in the sequence of holes reported on November 4.

Assay results are summarized in the table below:

Hole # Line Station Az Dip Depth From               (m) To           (m) Length     (m) Grade            (g/t Au) Zone(s)
MB-10-108 1+00 W 2+40 N N180° -56° 474.0 298.6 322.6 24.0 0.84 E
          including 318.0 319.2 1.2 5.58 E

          including 196.6 197.6 1.0 23.00 Z
            247.7 256.7 9.0 1.78 B-C1
          including 251.3 252.3 1.0 10.40 B
                     

Drill holes MB-10-108 and MB-10-109 were collared within the central portion of the Marban gold deposit and tested the Marban Mine Sequence from surface to a vertical depth of 360 metres. The Mine Sequence, consisting of deformed mafic volcanic rocks, is approximately 250 metres wide in this area and hosts several important sulphide and gold mineralised shear zones extending along a known strike length of 1.3 kilometre. 

The initial phase of the drilling program under the Aurizon option is confirming the geological and structural model and the continuity to the gold mineralised zones at Marban. To date, 36 holes and two (2) extensions were completed and two (2) holes are in progress for a total of 11,313 metres. Results for 22 completed holes are pending.

Aurizon Option

Aurizon can earn up to a 65% interest the Marban Block property under the terms of an option and joint venture agreement dated July 5, 2010 between NioGold and Aurizon. The initial 50% interest can be earned by incurring expenditures of C$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 is the project operator during the initial earn-in period (see news release dated July 6, 2010).

The first year program under the terms of the option agreement includes 50,000 metres of diamond drilling. The program is mainly directed at better defining and increasing the near surface gold mineral resources at the Marban and Norlartic deposits on the Marban Block (news release dated September 7, 2010). Two drill rigs are currently in operation at the Marban deposit.

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. The core was sealed 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), a Qualified Person as defined by National Instrument 43-101. This news release was prepared by Rock Lefrançois, P.Geo. (OGQ), the Company's President and a Qualified Person as defined by National Instrument 43-101.
