NioGold Mining Corp. Obtains 65.8 Percent Gold Recovery on Marban Column Leach Tests

Montreal, November 11, 2015 - NioGold Mining Corp. (TSX-V: NOX) (OTCQX: NOXGF) ("NioGold") is pleased to release the results of its preliminary column leach tests on composite samples from the Marban deposit, located on NioGold's 100% owned Marban Block property in the Malartic Gold camp, Abitibi District, Quebec. These tests are the first step in evaluating the potential for a stand-alone heap leach extraction of Marban gold mineralization.

Following initial satisfactory coarse bottle roll tests, standard six-inch column leach tests were done on two different grind sizes (quarter-inch or 4.2 mm and eighth-inch or 2.2 mm) of a composite created from six 100 kg samples. Results are summarized below for the two agglomerated ground composites:

	Feed Weight	Calculated Head Grade	Direct Head Grade	Average Crush	Leach Time	NaCN Consump.	Recovery
Test No.	(kg)	(g/t Au)	(g/t Au)	P80 (mm)	(days)	(kg/t)	Au %
CN-25	43.2	1.11	1.00	2.2	91	1.12	65.8
CN-26	43.4	1.00	1.00	4.2	91	1.11	65.4

Maximum recoveries of 65.8% were obtained from agglomerated eighth-inch grind (2.2 mm) over a 91 day leach period, with moderate cyanide consumption. Recoveries of quarter-inch (4.2 mm) material were comparable at the end of the 91 day run. Progressive recoveries over the 91-day leach time period are summarized in the next table, indicating relatively slow but not uncommon leach times for heap leach operations:

Test No.	Gold Extraction, % after no. days								Calc. Head Grade, Au g/t
	5	14	21	35	49	56	70	91
CN-25	21.4	40.4	47.4	54.9	59.9	61.5	63.6	65.8	1.11
CN-26	16.8	33.0	40.6	50.3	56.8	58.8	62.0	65.4	1.00

Robert Wares, P. Geo., NioGold's President and CEO, stated: "Leach results from this first run of samples were better than expected for Abitibi greenstones. Recovery for eighth-inch agglo-merated material is over 65%, which is comparable to many existing heap leach operations and is sufficiently encouraging to warrant further testing at different composite grades. Niogold will aggressively pursue work to determine the viability of a heap leach operation at Marban."
