NioGold Continues to Outline New Gold Mineralisation Around Former Marban Mine

VAL-D'OR, QUEBEC--(Marketwire - Sept. 5, 2007) - NioGold Mining Corporation (TSX VENTURE:NOX)(FWB:NG1) ("NioGold") reports on results of the 2007 drilling program on the Marban Block property, located in the Malartic Gold Camp, Quebec.

The initial phase of the 35,000-metre 2007 drilling program is investigating the Marban Mine sector, one of three former gold producers on the Marban Block property. To date, NioGold has completed 17 holes for 7,265 metres (MB-07-003 to MB-07-019) drilled on three north-south sections located 350 to 550 metres east of the Marban Mine shaft (Sections 3+50E, 4+50E and 5+50E). The holes investigated the surface and depth extension of the Marban Mine Sequence over a strike length of 200 metres and to a maximum dip extent of 700 metres. All holes intersected disseminated sulphide and vein stockwork zones typical of the Marban Mine ores.

Assay results received from holes MB-07-003 to MB-07-012 highlight the gold enriched nature of the Marban Mine Sequence and its potential to host disseminated bulk-style of mineralisation with higher grade sections. Assay results for holes MB-07-013 to MB-07-019 are pending. The most outstanding gold mineralised intervals obtained from the first 12 holes in the Marban Mine sector, including the initial 2 holes completed in late 2006 (MB-06-001 and MB-06-002), are listed below:

The 2007 drilling over the Marban Mine sector will continue to investigate the 4 priority targets outlined by the compilation of historical data, namely the near surface and down-dip extent of the Mine Sequence and the faulted off east and west extent of the Marban Mine orebodies.

To the north of the Marban Mine, hole MB-07-012 collared into previously unrecognized intrusive-hosted vein stockworks and associated alteration and sulphide mineralization returning anomalous gold values with several intervals grading above 1 g/t Au. The veined and mineralized sections bear strong similarities to Agnico-Eagle's Goldex deposit (21.4 million tonnes grading 2.39 g/t Au equals 1.64 million ounces of gold, Agnico-Eagle Mines Ltd., 2005), located 10 kilometres to the southeast. Follow-up holes are planned.

Complete assay results of holes MB-07-003 to MB-07-012 for intervals grading over 1 g/t Au are tabulated below. Reported intervals are in core lengths. Additional drilling is needed to estimate true widths and verify the continuity of the mineralised sections from hole to hole.

Quality Assurance / Quality Control and Qualified Persons

Diamond drill holes were drilled with NQ-size core in order to obtain larger sample volumes for the mineralised zones. The core was delivered by the drilling contractor to NioGold's facilities located at the Norlartic mine site. The core was photographed for reference, logged and mineralized sections were sawed in half. Sample lengths varied between 0.5 to 1.5 metres. The half core samples were bagged, sealed and trucked to Activation Laboratories Limited ("Actlabs") in Ancaster, Ontario, an accredited laboratory. 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 duplicates in the sample batches sent to the laboratory and a systematic re-assaying from the remaining coarse reject fraction by the fire-assay method with an atomic absorption finish for samples returning values of 2 to 5 g/t Au and by gravimetric finish for samples returning values greater than 5 g/t Au. As well, 10% of the pulps are sent to Bourlamaque Assay Laboratories Ltd. in Val-d'Or for check assaying.

The exploration programs are conducted under the supervision of Bertrand Brassard, M.Sc., P.Geo. (OGQ), also a Qualified Person as defined by National Instrument 43-101.
