Val-d'Or, Quebec, April 26, 2007. NioGold Mining Corporation (TSX-V: NOX) (FWB: NG1) is pleased to announce that it has initiated a 35,000-metre Phase II drilling program on the Marban Block property located in the Malartic Gold Camp, Quebec. A drill rig is presently set-up in the Marban Mine area where 10,000 metres of drilling has been planned.

 

The Marban Mine is situated on the east side of the Marban Block property and lies along a broad deformation zone commonly named the Marban Shear. From 1961 to 1974, Marban Gold Mines mined 2.0 million tonnes of ore at an average grade 5.27 grams per tonne (g/t) gold, yielding over 330,000 ounces of gold (Marban Gold Mines and MNRQ files). The orebodies occur as disseminated sulphide and vein stockwork zones hosted within a sequence of mafic volcanic and/or intrusive units here named the Marban Mine Sequence. The mine was developed over a lateral distance of 800 metres on 3 levels (500, 650 and 800) located between -150 to -245 metres vertical depth.

 

The geological setting and style of mineralization at the Marban Mine is comparable to the large S-50 Zone at the Kiena Mine Complex, located 5 kilometres on strike to the southeast. Mine production from the S-50 Zone (1981-2002) amounted to 10.7 million tonnes grading 4.75 g/t gold yielding 1.56 million ounces of gold (Wesdome Gold Mines). Local tight folding of the stratigraphic units is interpreted to be an important control on the localization of economic gold concentrations at both the Marban and Kiena mines.

 

In 2006, NioGold completed 10,000 metres of drilling in 63 holes on the Marban Block property including two holes (MB-06-001 and MB-06-002) drilled in the fall to investigate the Marban Mine area. Hole MB-06-001 discovered near surface disseminated sulphide mineralization above the Marban Mine workings within units similar to the Marban Mine Sequence. The mineralized zone returned an average of 3.6 g/t gold over 26.4 metres including 10.8 g/t gold over 4.0 metres (refer to press release dated December 19, 2006). Hole MB-06-001 cut a second thick sulphide mineralized zone starting at 440 metres vertical depth along the down-dip depth extent of the Marban Mine Sequence. This second zone averaged 1.3 g/t gold over 43.0 metres including 6.9 g/t Au over 2.0 metres. Hole MB-06-002 confirmed the near surface gold mineralization cut by hole MB-06-001 returning 8.0 g/t gold over 2.2 metres.

 

The 2006 drilling highlighted the potential to outline bulk-style gold mineralization in proximity to the mined out orebodies within the prospective Marban Mine Sequence. The 2007, 10,000-metre, drill program planned over the Marban Mine area will investigate 4 priority targets:

 

1) near surface fold closure of the Marban Mine Sequence
2) down-dip depth extent of the Marban Mine Sequence
3) faulted off east extent of the Marban Mine orebodies
4) faulted off west extent of the Marban Mine orebodies

 

The goal of the 2007 drilling program is to outline a large tonnage (>10M tonnes) deposit similar to that found at the S-50 Zone at Kiena.

 

Resource Estimations

 

Independent consultants Mine Development Associates of Reno, Nevada is progressing with the mineral resource estimations of the Norlartic and Kierens gold zones located on the Marban Block property. The resources are being estimated with an emphasis on evaluating the bulk tonnage potential. The resource estimates are expected to be completed during the month of May.
