NioGold Finds Uranium on Pump Lake

VAL-D'OR, QUEBEC--(Marketwire - Sept. 11, 2007) - NioGold Mining Corporation (TSX VENTURE:NOX)(FRANKFURT:NG1) ("NioGold") reports on the first phase of prospecting on the Pump Lake property, Quebec.

As anticipated, initial prospecting in July on the Pump Lake property resulted in the discovery of two uranium occurrences, named the Roxane and Emma showings. The showings lie along a newly defined radioactive structural trend where significant values of up to 0.24% U3O8 (4.7 lbs / ton U3O8) were obtained. The Pump Lake property was further enlarged to 150 square kilometres to cover the most prospective ground along this trend.

Roxane Showing: A northeast-southwest trending swarm of radioactive granitic intrusive dykes, possibly related to the Lesueur Alkaline Intrusive Complex, was discovered on the west side of the property. The dyke swarm was traced and prospected over a distance of 1 kilometre. Thirty-two (32) grab samples of outcrop of the intrusive material were taken with 16 samples returning assay values ranging from 0.01% to 0.20% U3O8 (0.2 to 4.0 lbs / ton U3O8). Higher values, ranging from 0.05% to 0.20% U3O8 (1.1 to 4.0 lbs / ton U3O8), were obtained in 8 samples all collected within a 200 metres stretch at the west end of the prospected area.

Emma Showing: A second isolated occurrence was discovered 6 kilometres on strike to the northeast of the Roxane showing. Sampling of a small trench dug over a radiometric anomaly returned assay values of up 0.24% U3O8 (4.7 lbs / ton U3O8). The Emma showing occurs in altered meta-sedimentary rocks possibly on the margin of underlying intrusive rocks.

In the past, the Pump Lake sector has undergone very limited exploration, particularly for uranium. The Roxane and Emma uranium occurrences were uncovered by field investigation of priority targets outlined by the airborne geophysical and geochemical surveys and structural lineament study completed during the spring. Detailed investigation is currently in progress over the Roxane showing. A field grid at 50-metre line spacing is being established over a 2.6 kilometre by 1.0 kilometre area. Abitibi Geophysics of Val-d'Or is conducting radiometric and magnetic geophysical surveying over the grid. Geophysical data is made available on a daily basis for prompt field investigation. Further prospecting along the northeast-southwest Roxane-Emma trend is planned.

Pump Lake is located 50 kilometres north of the Mt-Laurier uranium district, Quebec. Under the terms of an option agreement with Ressources Maxima inc. ("Maxima"), NioGold is earning a 100% interest in the Pump Lake property by paying a total of $100,000, issuing a total of 500,000 common shares to Maxima and incurring at least $500,000 of exploration expenditures.

Quality Assurance / Quality Control and Qualified Persons

The rock samples were bagged and sealed by NioGold personnel and delivered to ALS-Chemex in Val-d'Or, Quebec, an accredited laboratory. The samples were analysed for 38 elements by lithium meta-borate fusion and ICP-MS for quantitative results of all elements, including those encapsulated in resistive minerals. Samples returning uranium values greater than 1,000 ppm (0.1% U) were re-analysed by lithium borate 50:50 flux and XRF method.

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.
