NioGold Mining Corp. cuts 3.54 g/t Au over 15.2 metres at Marban

Val d'Or, October 27, 2015 - NioGold Mining Corp. (TSX-V: NOX) (OTCQX: NOXGF) ("NioGold") is pleased to release the results of thirty (30) new diamond drill holes of its resource definition program on the modelled open pit shell of the Marban deposit, located on NioGold's 100% owned Marban Block property in the Malartic Gold camp, Abitibi District, Quebec.


Drilling highlights from this set of holes include:

• -19.82 g/t Au over 1.0 m and 20.09 g/t Au over 1.1 m in drill hole MB-15-491 at 75 m and 155 m vertical depth respectively.

  -2.44 g/t Au over 10.5 m in drill hole MB-15-494 at 210 m vertical depth.

  -1.57 g/t Au over 22.4 m in drill hole MB-15-496 at 260 m vertical depth.

  -1.22 g/t Au over 22.4 m in drill hole MB-15-501 at 40 m vertical depth.

  -2.06 g/t Au over 13.2 m in drill hole MB-15-506 at 210 m vertical depth.

  -29.43 g/t Au over 1.2 m and 1.87 g/t Au over 16.4 m in drill hole MB-15-514 at 30 m and 150m vertical depth respectively.

  -3.54 g/t Au over 15.2 m and 2.25 g/t Au over 14.2 m in drill hole MB-15-517 at 210 m and 245 m vertical depth respectively.

These thirty new holes total 7,021 metres. So far, a total of 179 drill holes for a cumulative length of 52,526 meters have been released. A final press release will disclose remaining results within two weeks time.

The drilling campaign ended on August 13 with a total of 72,661 metres drilled, distributed in 246 holes and one extension of a hole from a previous campaign. An update of the geological interpretation is underway in view of the next resource estimate.

Results from holes MB-15-491 to MB-15-520 are summarized in the table below. The intercepts labelled "New" should allow for the definition of new lenses:

Technical Info. QA/QC and Qualified Persons

Drill orientations are roughly perpendicular to dip of mineralized zones and true widths of mineralized zones represent minimum 90% of reported core intervals.

Diamond drill holes were drilled with NQ-size core, except for holes that traversed underground workings which were completed using BQ-size core. The core was sealed and delivered by the drilling contractor to NioGold's facilities located at the Norlartic mine site. The core was photo-graphed 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 Actlabs in Ste-Germaine Boule, Quebec, which is 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 3 g/t Au by fire-assay using a gravimetric finish. As well, pulps grading above 0.5 g/t Au or mineralized intervals are sent to a second laboratory for check assaying.

Drill program design and monitoring, core logging and sample preparation are being executed at NioGold's facilities in Val d'Or, under the supervision of Yan Ducharme. M.Sc., P.Geo. (OGQ). NioGold's Vice-President Exploration and a Qualified Person as defined by National Instrument 43-101. QA/QC program utilized is consistent with NI 43-101 and industry best practice standards. This news release was prepared by Mr. Ducharme.
