NIOGOLD REPORTS PRELIMINARY LEACH TEST RESULTS AT MARBAN

Niogold Mining Corp. has released the results of 50 bottle-roll leach tests on representative mineralized core samples from the Marban deposit, located on Niogold's 100-per-cent-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 per cent over a grade range of 0.22 gram per tonne gold to 4.40 grams per tonne gold (average 1.39 grams per tonne gold), with average cyanide (NaCN) consumption of 0.17 kilogram per tonne. Results are summarized for four sample populations.

Four samples in the 1.20 g/t Au to 2.30 g/t Au range gave poor results (less than 78-per-cent 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 per cent with a range of 81.3 per cent to 98.0 per cent across the entire sample population.

Robert Wares, PGeo, Niogold's president and chief executive officer, stated: "Leach results from this first run of samples are excellent. Average recovery around the 88- to 89-per-cent 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 50 samples will be sent for leach tests at SGS Mineral Services in order to confirm preliminary test results and improve statistics on the grade/recovery curve.
