NioGold Reports Preliminary Leach Test Results at Marban

July 06, 2015

Val d'Or, Quebec -- NioGold Mining Corporation (TSX-V: NOX) (OTCQX: NOXGF) ("NioGold" or the "Company") is pleased to release the results of fifty (50) bottle-roll leach tests on representative mineralized core samples from the Marban deposit, located on NioGold's 100% owned Marban Block property in the Malartic gold camp, Abitibi District, Quebec.

Samples were ground to an average of 65 microns and leached for 36 hours, similar to leaching conditions at the nearby Canadian Malartic mine. Results indicate an average recovery of 88.3% over a grade range of 0.22 to 4.40 g/t Au (avg. 1.39 g/t Au) with average cyanide (NaCN) consumption of 0.17 kg per tonne. Results are summarized below for four sample populations:

Number of Samples Grade Range (calc. g/t Au) Avg. Grade (calc. g/t Au) Avg. P80 microns NaCN Consumption kg/t Recovery Range Au % Average Recovery Au %
8 0.22 - 0.50 0.37 62.3 0.13 83.3 - 93.8 89.5
23 0.51 - 1.50 0.90 65.8 0.18 78.6 - 96.1 89.7
14 1.51 - 2.50 2.07 64.0 0.19 71.9 - 98.1 85.4
5 2.51 - 4.40 3.34 66.4 0.16 81.3 - 98.0 88.1
Average 0.22 - 4.40 1.39 64.8 0.17 - 88.3

Four samples in the 1.20-2.30 g/t Au range gave poor results (less than 78% recovery), possibly due to the presence of coarser gold grains. Check analyses will be performed on these samples to confirm results. If these four samples are excluded from the set, the average recovery is 89.5% with a range of 81.3% to 98.0% across the entire sample population.

Robert Wares, P. Geo., NioGold's President and CEO, stated: "Leach results from this first run of samples are excellent. Average recovery around the 88-89% mark is comparable to Canadian Malartic ore under similar leach times and cyanide consumption levels. More importantly, the average recoveries at Marban are close throughout the four sample populations, giving a flat grade/recovery curve with no significant drop in lower grade material. This is a very positive feature of the deposit and will be confirmed with additional testing."

An additional set of fifty samples will be sent at for leach tests at SGS Mineral Services in order to confirm preliminary test results and improve statistics on the grade/recovery curve.
