DRILLING PROVES STRONG POTENTIAL AROUND FORMER
MARBAN MINE
Val-d'Or, Quebec, September 25, 2007: NioGold Mining Corporation (TSX-V: NOX) (FWB: NG1)
("NioGold") reports on results of the 2007
drilling program on the Marban Block property,
located in the Malartic Gold Camp, Quebec. Holes
MB-07-013 and MB-07-014 and the extension of hole
MB-07-007 generate solid results along the depth extent of the prospective
units hosting the former Marban Mine orebodies (Mine Sequence). The holes returned best
intervals of:
MB-07-007: 15.5
g/t Au over 1.8 m
MB-07-013: 6.5 g/t Au over 3.0 m and 2.4 g/t Au over 9.0 m (incl. 5.2 g/t Au over 2.0 m)
MB-07-014: 7.9 g/t Au
over 1.0 m,
18.5 g/t Au over 0.5 m,
8.3 g/t Au over 1.5 m
and 6.0 g/t Au over 1.0 m
To date, NioGold has
completed 20 drill holes for 9,120 metres (MB-06-001 to MB-07-020) drilled
on four north-south sections located east of the Marban
Mine shaft. Previously reported results (MB-06-001 to MB-07-012) and new
results received from holes MB-07-013, MB-07-014 and the extension of hole MB-07-007, tabulated below, indicate strong potential
to outline new gold deposits near surface and along the depth extent of the
Mine Sequence. Readers are invited to review the Marban
Surface Plan and Marban Section 450E available at www.niogold.com/marban. Assay
results for holes MB-07-015 to MB-07-020 are pending.
The 2007 drilling continues to expand on the newly
discovered gold mineralisation near surface and along the depth extent of the
Mine Sequence. The faulted off east and west extent of the Marban
Mine orebodies is a priority target still to be
tested.
Norlartic-Kierens
Resource Drilling
Apart from the Marban Mine
sector, a drill rig was mobilized to the northern part of the Marban Block property where 12,000 metres are
planned to expand on the gold resources defined in proximity to the former Norlartic and Kierens Mines. In
June, NioGold released National Instrument 43-101
compliant indicated and inferred resources estimates of 72,000 and 270,000 ounces gold,
respectively (see News Release dated June 28, 2007). Readers are invited to
review the Norlartic Kierens
Section available at www.niogold.com/marban for the
location of the main drill target areas.

Quality Assurance / Quality Control and
Qualified Persons
Diamond drill holes were drilled with NQ-size core in
order to obtain larger sample volumes for the mineralised zones. The core was
delivered by the drilling contractor to NioGold's
facilities located at the Norlartic mine site. The
core was photographed for reference, logged and mineralized sections were sawed
in half. Sample lengths varied between 0.5 to 1.5 metres. The half
core samples were bagged, sealed and trucked to Activation Laboratories Limited
("Actlabs") in Ancaster, Ontario,
an accredited laboratory. 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
duplicates in the sample batches sent to the laboratory and a systematic
re-assaying from the remaining coarse reject fraction by the fire-assay method
with an atomic absorption finish for samples returning values of 2 to 5 g/t Au
and by gravimetric finish for samples returning values greater than 5 g/t Au. As
well, 10% of the pulps are sent to Bourlamaque Assay
Laboratories Ltd. in Val-d'Or for check assaying.

programs are conducted under the supervision of Bertrand Brassard, M.Sc., P.Geo. (OGQ), also a Qualified
Person as defined by National Instrument 43-101.
