Niogold And Aurizon Commence Drilling On The Marban Block Property

September 7, 2010

Val-d’Or, Quebec - September 7, 2010 - NioGold Mining Corporation (TSX-V:NOX, Frankfurt:NG1) is pleased to announce that drilling operations have commenced on the Marban Block property under the terms of the Aurizon Mines Ltd. (“Aurizon”) option agreement. A C$5.9 million program was approved for the first year of the option that includes 50,000 metres of diamond drilling. Two drill rigs were mobilised on the property on August 30 and a third drill rig will be added later in the program.

As reported on July 6, Aurizon can earn a 50% interest in the Marban Block property, subject to underlying royalties, by:

• Incurring expenditures of C$20 million over three years, of which a minimum of C$5.0 million is a firm commitment to be spent in the first year;

• completing an updated NI 43-101 compliant mineral resource estimate;
  
• making a resource payment equal to the sum of C$30 (or C$40 if the price of gold is then above US$1,560) multiplied by 50% of the number of total gold ounces in the Measured and Indicated resource categories plus C$20 (or C$30 if the price of gold is then above US$1,560) multiplied by 50% of the number of total gold ounces in the Inferred resource category.

Aurizon can earn an additional 10% interest, for an aggregate of 60%, by delivering a feasibility study, and an additional 5%, for an aggregate 65%, by arranging project financing for capital expenditures estimated by the feasibility study to place the project into commercial production. NioGold will be operator during the initial earn-in period and Aurizon will provide input on exploration programs and will become operator after their initial 50% interest has been earned.

The first year drilling program will be mainly directed at better defining and increasing the near surface gold resources at the Marban and Norlartic deposits:

• Marban Deposit:
  
  • 30,000m of shallow drilling, from surface to -300m vertical depth, to complete drill hole pattern at 50m spacing and select in-fill drilling at 25m spacing;
    
  • 5,000m to 10,000m of drilling along depth extent of the Marban Mine Zones and Mine Sequence, principally between -300m to -500m vertical depth.
    
• Norlartic Deposit: 5,000m to 10,000m of select shallow drilling, from surface to -200m vertical depth, to complete drill hole pattern at 50m spacing.
  
• Exploration: 5,000m of drilling to investigate the lateral extent of deposits and high-grade quartz-gold vein systems along the Gold Hawk Horizon.
