NIOGOLD CONTINUES TO EXPAND
AROUND HISTORIC MARBAN MINE
Val-d'Or, Quebec, July 11, 2007.
NioGold Mining Corporation (TSX-V: NOX) (FWB: NG1) ("NioGold") reports
on first results of the 2007 drilling program on the Marban Block property,
located in the Malartic Gold Camp, Quebec.
Complete assay results were received for
the first four holes (MB-07-003 to MB-07-006) drilled to test the near-surface
extent of the Marban Mine Sequence above and to the north of the former Marban
mine workings. All holes returned gold mineralised intervals and expanded
significant mineralisation reported in 2006 in hole MB 06 001
The initial phase of the 35,000-metre 2007 drilling
program is targeting the Marban Mine area, one of the several priority targets
being investigated on the Marban Block in order to increase gold resources that
are presently estimated at the Norlartic and Kierens deposits (see News Release
dated June 28, 2007). The results from the first four holes continue to confirm
the gold enriched nature of the Marban Mine Sequence and its potential to host
disseminated bulk-style of mineralisation.
To date, NioGold has completed a north-south fence
of ten holes (MB-07-003 to MB-07-012) drilled 450 metres east of the Marban mine
shaft (Section 4+50E). The holes investigated the surface and depth extent of
the Mine Sequence over a dip extent of 550 metres. All holes intersected
disseminated sulphide and vein stockwork zones typical of the gold-bearing
intervals cut in hole MB 06 001 drilled on Section 5+00E. Hole MB-06-001
returned a near-surface cut of 3.6 g/t Au over 26.4 metres (incl. 10.8 g/t Au
over 4.0 m) and 1.3 g/t Au over 43.0 metres (incl. 6.9 g/t Au over 2.0 m) at
depth. Complete assay results are pending for holes MB-07-007 to
The drill rig was moved 100 metres to the east to
complete a second fence of holes across the Mine Sequence on Section
Quality Assurance / Quality Control and
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.
