Niogold Commences Exploration Drilling In New Sector At Malartic

Val-d'Or, Quebec - March 3, 2011 - NioGold Mining Corporation (TSX-V:NOX) ("NioGold" or the "Company") has begun site preparation for the mobilisation of a drill rig to the southern portion of the Company's large Malartic Block property, located 20 kilometres west of Val‑d'Or and directly adjacent to Osisko Mining Corp.'s ("Osisko") Canadian Malartic mine development project.

NioGold plans an initial 6,000 metres of exploration drilling to investigate sedimentary formations on the north side of the famous Cadillac fault in proximity to the Canadian Malartic and Barnat deposits and Jeffrey Zone being developed by Osisko. The Canadian Malartic project presently boasts open pit reserves of 245.8 million tonnes at an average grade of 1.13 g/t Au for 8.97 million contained gold ounces. Canadian Malartic is now recognised as a porphyry-type gold system hosted within diorite porphyry intrusions and altered sediments on the south side of the Cadillac fault.

Despite the obvious potential within the southern portion of the Malartic Block property, no sustained exploration programs have been conducted over the area in the past, in part due to the lack of rock exposure. NioGold ranks this sector as a high priority target for a new discovery. The drilling will test a combination of magnetic, electro-magnetic and induced polarisation geophysical anomalies and gold in-soil anomalies.

This news release was reviewed by Rock Lefran?s, P.Geo. (OGQ), the Company's President and a Qualified Person as defined by National Instrument 43-101.

The above information regarding the Canadian Malartic Project was obtained from technical reports available on the Osisko website, and should be read in reference to the full reports, including all cautionary statements and disclaimers therein.
