Marban Western High Grade ZoneReturns 7.28 G/T Au Over 7.2 Metres


(via Thenewswire.ca)

Val-d'Or, Quebec - June 12, 2012 - NioGold Mining Corporation (TSX-V:NOX) (OTCQX:NOXGF) ("NioGold") is pleased to report additional results from the Phase Two drilling program conducted under the terms of the earn-in option of Aurizon Mines ("Aurizon") on the Marban Block property, located in the Malartic gold camp, Abitibi region of Quebec. These results are in continuation of the previously very encouraging results of the Phase Two published previously (see news release of March 1st and April 26th).

Results from 22 new drill holes and three (3) extensions of previous holes were obtained on the Marban gold deposit and are included in this release. The drill results are tabled on the following pages.

The new results highlight the presence of wide mineralised intervals, as well as smaller high grade intervals mainly located within the Western High Grade Zone ("WHGZ"), which is located immediately west of the former Marban Mine, from surface down to a depth of 250 metres.

Drilling highlights include:

-The best results from the in-fill drill holes on the WHGZ returned the following:

-5.13 g/t Au over 6.0 m on section 3700 at a vertical depth of 230 m (MB-12-282)

-4.67 g/t Au over 13.0 m on section 3675 at a vertical depth of 140 m (MB-12-284)

-26.10 g/t Au over 1.2 m, 7.28 g/t Au over 7.2 m and 39.50 g/t Au over 1.0 m on section 3650 at a vertical depth of 95 m, 125 m and 130 m respectively (MB-12-297)

-24.60 g/t Au over 1.2 m on section 3575 at a vertical depth of 30 m (MB-12-300)

-45.80 g/t Au over 1.0 m on section 3800 at a vertical depth of 75 m (MB-12-306)

-Shallow high grade intervals were also obtained along the Marban deposit:

-24.20 g/t Au over 0.5 m on section 4350 at a vertical depth of 22 m (MB-12-275)

-39.10 g/t Au over 1.2 m on section 3950 at a vertical depth of 115 m (MB-12-287)

The 25 holes are distributed along a strike of 950 metres along the Marban deposit and they are contributing to improve the quality of the near surface resource.

The Phase Two drilling program started on December 13, 2011 and concluded on May 31st with a total of 34,656 metres distributed in 90 holes and nine (9) extensions of previous holes. An updated mineral resource estimate based on the Phase One drill results, as well as basic technical studies, including metallurgical test work (see news release of April 24th), should be completed by the end of the second quarter, 2012.

Marban deposit drilling

The 2010-2012 drill programs confirmed the geological model interpreted by NioGold and therefore the continuity of the mineralised zones. They were also instrumental in developing the shallow area called the Western High Grade Zone and identification of the Eastern Down Dip Zone which is located below a vertical depth of 250 metres and remains open at depth and laterally.

Aurizon Option

Aurizon can earn up to a 65% interest the Marban Block property under the terms of an option and joint venture agreement dated July 5, 2010, between NioGold and Aurizon. The initial 50% interest can be earned by incurring expenditures of $20 million over three years, completing an updated NI 43-101 compliant mineral resource estimate, and by making a resource payment for 50% of the total gold ounces defined by the mineral resource estimate. NioGold remains the project operator during the initial earn-in period (see news release dated July 6, 2010).

Technical Info, QA/QC and Qualified Persons

Reported intervals are in core lengths but are anticipated to approximate true width, except where structural complexities occur, as the holes were drilled near perpendicular to the principal local structural orientation.

Diamond drill holes were drilled with NQ-size core in order to obtain larger sample volumes of the mineralised zones, except for holes that traversed underground workings which were completed using BQ-size core. The core was sealed delivered by the drilling contractor to NioGold's facilities located at the Norlartic mine site. The core was photographed for reference, logged and mineralised sections were sawed in half. Sample lengths vary between 0.5 to 1.5 metres. Half core samples were bagged, sealed and delivered to ALS Chemex in Val-d'Or, Quebec, an accredited laboratory. The remaining core is stored on site for reference. 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 field duplicates in the sample batches sent to the laboratory and a systematic re-assaying of samples returning values above 2 g/t Au by the fire-assay method using a gravimetric finish. As well, pulps grading above 0.5 g/t Au are sent to Bourlamaque Assay Laboratories Ltd. in Val-d'Or for check assaying.

The drilling program is conducted under the supervision of Yan Ducharme, M.Sc., P.Geo. (OGQ), the NioGold Vice president of exploration and a Qualified Person as defined by National Instrument 43-101. The news released was prepared by Mr. Ducharme.

NioGold Mining Corporation (NOX.V) Announces New Zone Discovered Hole Returned 19.21 G/T AU Over 5.6 Metres


(via Thenewswire.ca)

Val-d'Or, Quebec - August 15, 2012 - NioGold Mining Corporation (TSX-V:NOX) (OTCQX:NOXGF) ("NioGold") reports that Phase Two exploration on its Marban Block property in Quebec has identified a new high grade gold zone and extended the Marban deposit on strike and at depth. The results from 31 drill holes conclude a very successful program conducted under the $20 million earn-in option to be spent by Aurizon Mines ("Aurizon") on the property. Approximately $9 million remains on the commitment. The Marban Block is located in the Malartic gold camp, Abitibi region of Quebec.

The new gold zone was discovered at about 500 metres north of the Marban deposit and at 350 metres south of the Norlartic deposit. Two holes intersected a mineralized dioritic dike.

The results of the new zone are:

-19.40 g/t Au over 1.2 m on section 3600 at a vertical depth of 92 m (MB-12-323)

-19.21 g/t Au over 5.6 m on section 3600 at a vertical depth of 215 m (MB-12-324)

This discovery occurred in the 13 exploration holes which were drilled outside the Marban deposit limits. One hole investigating the stratigraphy of the Marban deposit at great depth revealed the continuity of the Marban system down to a depth of 780 vertical metres with hole MB-12-322 (1.77 g/t Au over 6.5 m) which is about 450 metres from the deepest information on that section of the deposit. North of the Marban deposit, a group of 5 holes intersected the Norlartic system thus confirming its eastern extension.

Results from the 18 others holes that were drilled on the Marban deposit are distributed on a strike of 1,025 meters and include the Eastern Down Dip Zone ("EDDZ") and Western High Grade Zone ("WHGZ").

Drilling highlights from the EDDZ include:

-3.74g/t Au over 6.4 m on section 4700 at a vertical depth of 245 m (MB-12-317)

-4.51 g/t Au over 6.0 m on section 4600 at a vertical depth of 375 m(MB-12-319)

In-fill drill holes on the WHGZ include the following highlights:

-19.35 g/t Au over 1.2 m on section 3725 at a vertical depth of 100 m (MB-12-309)

-20.70 g/t Au over 0.7 m and 14.65 g/t Au over 1.2 m on section 3675 at a vertical depth of 50 m and 60 m respectively (MB-12-312)

-1.31 g/t Au over 19.7 m on section 3700 at a vertical depth of 35 m (MB-12-314)

-21.40 g/t Au over 0.9 m on section 3850 at a vertical depth of 30 m (MB-12-327)

"These are extremely encouraging results," said Mike Iverson, NioGold's Chairman and CEO. "We made a new discovery between the Marban and Norlartic deposits. We extended the Eastern Down Dip Zone with wide, high-grade intervals, while in-fill drilling in the Western High Grade Zone continued to deliver high grade values over small widths and lower grade intervals over larger widths. We look forward to the Phase Three program, which NioGold and Aurizon expect to begin in late August or early September."

Marban Block drilling

The 2010-2012 drill programs (Phase 1 and 2) totalled 84,911 metres (260 holes and 17 extensions). The Marban deposit received the bulk of the drilling with 68,861 metres (208 holes), among which 19,575 metres (74 holes) were in-filling at a 25x25 metres spacing pattern. The other holes were completing a 50x50 metres spacing pattern or making steps of 100 metres. The Norlartic deposit received 4,319 metres (21 holes) of in-fill drilling and 11,731 metres (31 holes) were drilled for exploring the Marban Block property mainly between the Norlartic and Marban deposits, but also some other targets on the property.

Aurizon Option

Aurizon can earn up to a 65% interest the Marban Block property under the terms of an option and joint venture agreement dated July 5, 2010, between NioGold and Aurizon. The initial 50% interest can be earned by incurring expenditures of $20 million over three years, completing an updated NI 43-101 compliant mineral resource estimate, and by making a resource payment for 50% of the total gold ounces defined by the mineral resource estimate. NioGold remains the project operator during the initial earn-in period (see news release dated July 6, 2010).

Technical Info, QA/QC and Qualified Persons

Reported intervals are in core lengths but are anticipated to approximate true width, except where structural complexities occur, as the holes were drilled near perpendicular to the principal local structural orientation.

Diamond drill holes were drilled with NQ-size core in order to obtain larger sample volumes of the mineralised zones, except for holes that traversed underground workings which were completed using BQ-size core. The core was sealed delivered by the drilling contractor to NioGold's facilities located at the Norlartic mine site. The core was photographed for reference, logged and mineralised sections were sawed in half. Sample lengths vary between 0.5 to 1.5 metres. Half core samples were bagged, sealed and delivered to ALS Chemex in Val-d'Or, Quebec, an accredited laboratory. The remaining core is stored on site for reference. 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 field duplicates in the sample batches sent to the laboratory and a systematic re-assaying of samples returning values above 2 g/t Au by the fire-assay method using a gravimetric finish. As well, pulps grading above 0.5 g/t Au are sent to Bourlamaque Assay Laboratories Ltd. in Val-d'Or for check assaying.

The drilling program is conducted under the supervision of Yan Ducharme, M.Sc., P.Geo. (OGQ), the NioGold Vice president of exploration and a Qualified Person as defined by National Instrument 43-101. The news released was prepared by Mr. Ducharme.

Aurizon Announces an Updated Mineral Resource Estimate for Niogold's Marban Deposit




Val-d'Or, Quebec - September 7, 2012 - NioGold Mining Corporation (TSX-V:NOX) (OTCQX:NOXGF) ("NioGold") is pleased to announce that Aurizon Mines Ltd. ("Aurizon") has announced an updated mineral resource estimate for the Marban deposit. The deposit is located on NioGold's Marban Block property, in the Malartic gold camp, Abitibi region of Quebec, which is currently under option to Aurizon. Pursuant to the option, the parties have planned a three Phase drill program of which Phases 1 and 2 have been completed, and Phase 3 is in planning.

The updated mineral resource estimate, based on Phase 1 results, was prepared by SGS Canada Inc. - Geostat ("SGS Geostat") under guidelines set by Aurizon's personnel. All information of a scientific or technical nature in this release has been reproduced from Aurizon's news release dated September 7, 2012. NioGold has not at this time independently verified any of the scientific or technical information in Aurizon's news release and reproduced in this release.

Resource Estimate from Phase 1 (August 2010 - August 2011)

The updated mineral resource estimate integrates the results of NioGold's drill programs on the Marban deposit up to the mineral resource estimate prepared by Mine Development Associates ("MDA") on December 1, 2009, and the results of the Phase 1 drill program which was completed last year on August 9, 2011. The updated mineral resource estimate does not:

-incorporate the results of the recently completed Phase 2 drill program, comprised of 34,658 metres distributed in 90 new holes, that investigated the Marban deposit along strike, especially in the Western High Grade zone and the Eastern Down Dip zone

-incorporate the mineral resource estimates for the Norlartic and Kierens deposits, located north-west of the Marban deposit, which were previously reported on by MDA and which remain unchanged (see Table 4).

The Phase 1 drill program comprised a total of 41,270 metres distributed in 146 new holes, drilled between August 30, 2010 and August 9, 2011.

Based on a cut-off grade of 0.35 grams of gold per tonne and a high value capping of 25 grams of gold per tonne, the in-pit mineral resource is estimated at 20,700,000 tonnes at 1.58 grams of gold per tonne or 1,053,000 ounces of gold in the measured and indicated category plus at 3,780,000 tonnes at 1.60 grams of gold per tonne or 194,000 ounces of gold in the inferred category. The resource outside of the pit shell and using a cut-off grade of 2.0 grams of gold per tonne is estimated at 980,000 tonnes at 2.82 grams of gold per tonne or 89,000 ounces of gold in the measured and indicated category plus 800,000 tonnes at 2.68 grams of gold per tonne or 69,000 ounces of gold in the inferred category.

The mineral resource estimate has been calculated using the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definitions Standards for mineral resources in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

Mineral resources which are not mineral reserves do not have demonstrated economic viability.

Mineral resources update effective date: November 16, 2011.

1: Rounded to nearest 10 thousand.

2: High value capped at 25 g/t Au on assays.

3: Rounded to nearest 1 thousand.

"Following the resource estimate in 2010, our target was to increase the amount of ounces near surface on the Marban deposit to assess if an open pit scenario was possible. The results of this update of the resource estimate are showing that we achieved our goal" said Mike Iverson Niogold's President and CEO.

The in-pit and underground resources have been estimated based on the following parameters:

-Two distinct mining scenarios: open-pit and underground. The open pit mineral resources are reported within an initial Whittle pit shell;

-The base case scenario was performed with a minimum cut-off grade of 0.35 grams of gold per tonne;

-A total of 1,684 holes including 333 historical surface holes for a total of 136,789 metres of surface drilling and 1,205 historical underground holes for a total of 61,256 metres;

-A total of 858 underground channels and chips samples;

-A total of 107,904 assays which are available in the database;

-A capping of 25 grams of gold per tonne was applied to the assays.

-The mineral resources were modeled and estimated using SGS Proprietary software, Genesis 1.0.17;

-mineral resource model was interpreted from 144 transverse sections at intervals of 12.5 metres and from level plans at intervals of 5 metres;

-The interpolation was conducted on composite assays of 2 metres in length;

-The interpolation was done by Ordinary Kriging in two stages: One block model using mineralised envelopes for the high grade mineralisation (>0.5 grams of gold per tonne), and another block model for the lower grade mineralisation located outside the defined mineralised envelopes;

-The block model was defined by blocks of 5 metres long by 5 metres wide by 5 metres thick and covers a strike length of 1,400 metres to a maximum depth of 700 metres below surface;

-An average drill spacing of 25 metres x 25 metres was used for the measured and indicated resources;

-The average relative density used to calculate the tonnage of the Marban deposit was adjusted to 2.77 tonnes/cubic metre;

-The historical Marban production was removed from the mineral resources;

-The Whittle pit optimisation was performed by SGS Geostat using a gold price of US$1,350 per ounce and an exchange rate of 1:1;The simulated pit is 1,400 metres long, 850 metres wide and 350 metres deep. The mineral resources located outside the Marban deposit optimised pit shell is evaluated using an underground ("U/G") mining scenario. The base case cut-off grade for U/G mineral resources for the Marban deposit has been set at 2.0 grams of gold per tonne.

Sensitivity Analysis of the Resources

The mineral resource sensitivity is presented in the next 2 tables with different cut-off grades from 0.35 to 3.0 grams of gold per tonne.

Geology

The Marban mineralized system has a funnel shape corresponding to a 400 to 700 metres wide multi-folded structure in the upper part and a more steeply dipping root at depth, with thicknesses in the range of 100 to 200 metres. Mineralized zones and structures are developed in east-west oriented schistosed basalt altered to carbonate, chlorite and albite. Shear zones dip 45? to 70? to the north and are from 10 to over 70 meters wide. Gold grade typically correlates with an increasing density of quartz veining associated with disseminated pyrite and pyrrhotite. The hanging wall and footwall are composed mainly of ultramafic units.

The historical production from this mine is 1.98 million tonnes at 5.27 grams of gold per tonne for 330,000 ounces produced.

Marban Property Mineral Resources

The Marban deposit currently represents the core of the mineral resources located on the Marban property. The Norlartic and Kierens deposits represent two additional mineral resources, reported on by Mine Development Associates (MDA) December 1, 2009. The project comprises 3 mining lease and 42 claims covering 976 hectares.

The following table provides the details of the total mineral resources for the Marban Block property, as updated by the SGS September 2012 mineral resource estimate on the Marban deposit. Note that MDA's previous estimate on the Marban deposit used a cut-off grade of 2.5 g/t, compared to SGS's use of a cut-off grades of 0.35 g/t and 2.0 g/t.

Outlook from Phase 2 drilling program

The results of 90 holes and 9 extensions of previous holes of the Phase 2 of the drilling program have successfully confirmed the extension of the different zones of the Marban mineralized system (see the news releases dated March 1, April 26, June 12, and August 15 2012). The objectives of this program on the Marban deposit were to improve the quality of the near surface resources, developing a mineral inventory below a depth of 250 vertical metres and outside the known lateral extension.

An updated mineral resource will be produced in order to integrate the results of the Phase 2 drilling program in the resource estimate.

The preliminary metallurgical testwork at Marban indicates a favourable recovery between 95.4% and 97.6% for the ore cyanidation test (see news release dated April 24, 2012). The Bond ball mill testing indicated the ore fell in the medium soft to medium range of hardness compared to the SGS database (10.1-10.9 kWh/t).

A baseline environmental study has been initiated and being prepared by Golder Associates and should be completed by the end of the year.

A third phase of drilling will be initiated later this month. There is still $9M to be spent in the earn-in option with Aurizon.

Aurizon Option

Aurizon can earn up to a 65% interest the Marban Block property under the terms of an option and joint venture agreement dated July 5, 2010, between NioGold and Aurizon. The initial 50% interest can be earned by incurring expenditures of $20 million over three years, completing an updated NI 43-101 compliant mineral resource estimate, and by making a resource payment for 50% of the total gold ounces defined by the mineral resource estimate. NioGold remains the project operator during the initial earn-in period (see news release dated July 6, 2010).

Niogold Mining Corp. (NOX.V) Peter Hawley Appointed Chair



December 4, 2012 - NioGold Mining Corporation (TSX-V:NOX) (OTCQX:NOXGF) ("NioGold") is pleased to announce that Mr. Peter Hawley has accepted the appointment as Chairman of NioGold.

Mr. Hawley is a professional geologist with over 30 years experience in the mining industry, from grassroots exploration through to mine development and production, on projects throughout the Americas. He spent over 22 of those years working in the Val D'Or mining camp, including the Noralartic, Kierens and Marban mines - all of which are now part of NioGold's current land holdings and being actively re-evaluated by NioGold.

Mr. Hawley has worked extensively with a number of large and established mining companies, including Teck Corp., Noranda Inc., Placer Dome Inc., Aur Resources and Barrick Gold Corp. In 1998, he founded Scorpio Mining Corporation, a low cost underground silver producer in Mexico which is listed on the TSX with a market capitalization of $200 million.

NioGold Begins Program On Marban Block Property

Source: http://bit.ly/VZX05r

Val-d'Or, Quebec -- NioGold Mining Corporation (TSX-V: NOX) (OTCQX: NOXGF) ("NioGold") is pleased to announce that it has commenced a $1.6M exploration program on its Marban Block property, currently under option to Aurizon, to drill the Kierens and Norlartic deposits and the North zone.

The Marban Block property contains the Kierens, Norlartic and Marban deposits which have a collective resource estimate of 1.56 M ounces (28.5 millions of tonnes at 1.70 g/t) in the measured and indicated categories and 0.51 M ounces (9.6 millions of tonnes at 1.66 g/t) in the inferred category (see news release of September 7, 2012).

The drilling at Kierens and Norlartic will explore the open pit potential of these two deposits, further test their extensions in all directions, and attempt to convert the existing inferred resources to a higher category. Both require winter drilling programs due to the need to build ice bridges on the Keriens Creek, located north-east of the Kierens-Norlartic trend, in order to drill the upper part of the deposits.

The North zone is located about 200m northeast and parallel to the Norlartic zone, and consists of three sub-zones named A (north-easternmost), B (centermost) and C (south-westernmost). The drilling at the North zone will investigate the potential for a resource estimate and possible open pit scenario.

Due to the timing requirements for winter drilling, and in light of Aurizon's ongoing review of the Phase II data, Niogold has agreed to fund the exploration program at this time. The parties have further agreed, however, that upon Aurizon's decision to proceed with the Phase III program, Aurizon will immediately reimburse Niogold for the costs of the exploration program and such amount will then be applied to Aurizon's earn-in requirement.

Aurizon Option

Aurizon can earn up to a 65% interest the Marban Block property under the terms of an option and joint venture agreement dated July 5, 2010, between NioGold and Aurizon. The initial 50% interest can be earned by incurring expenditures of $20 million over three years, completing an updated NI 43-101 compliant mineral resource estimate, and by making a resource payment for 50% of the total gold ounces defined by the mineral resource estimate. NioGold remains the project operator during the initial earn-in period (see news release dated July 6, 2010).

Technical Info, Qualified Persons and QA/QC

The drilling programs are conducted under the supervision of Yan Ducharme, M.Sc., P.Geo. (OGQ), the NioGold Vice president of exploration and a Qualified Person as defined by National Instrument 43-101. The news released was prepared by Mr. Ducharme.

NioGold Mining Corporation (TSX-V:NOX) North Zone Drilling Expands Satellite Zone near Norlartic Deposit


(via Thenewswire.ca)

Val-d'Or, Quebec - April 4, 2013 - NioGold Mining Corporation (TSX-V:NOX) (OTCQX:NOXGF) ("NioGold") is pleased to announce the results of its 18 hole, 4,395 meter exploration drilling program of the North zone on the Marban Block (100% owned by NioGold and under option to Aurizon).

The Marban Block contains the Kierens, Norlartic and Marban deposits which have a collective resource estimate of 1.56 M ounces (28.5 millions of tonnes at 1.70 g/t) in the measured and indicated categories and 0.51 M ounces (9.6 millions of tonnes at 1.66 g/t) in the inferred category (see news release of September 7th, 2012).

The North zone is a satellite zone to the Norlartic deposit, located 200-300 metres northeast and parallel to Norlartic and consists of three sub-zones named A (north-easternmost), B (centermost) and C (south-westernmost).

Highlights from the North zone drill program include

4.47 g/t Au over 3.4 m in hole NL-13-074 at a vertical depth of 40 m.

3.75 g/t Au over 4.8 m and 2.93 g/t Au over 5.3 m in hole NL-13-078 at a vertical depth of 35 m and 45 m respectively.

15.41 g/t Au over 2.8 m in hole NL-13-080 at a vertical depth of 80 m.

1.45 g/t Au over 23.4 m in hole NL-12-066 at a vertical depth of 205 m.

1.81 g/t Au over 7.6 m in hole NL-13-071 at a vertical depth of 130 m.

Two holes that were drilled to test the North zone were extended to a depth that also intersected the adjacent Norlartic trend with the following results:

84.10 g/t Au over 1.2 m in hole NL-13-073 at a vertical depth of 215 m. For technical reasons, this hole was abandoned before crossing the entire Norlartic structure.

2.18 g/t Au over 24.7 m in hole NL-13-075 at a vertical depth of 260 m.

"We are very pleased with these results, they are in line with what we expected in the North zone" said Michael Iverson, President and CEO of NioGold. He added, "Our investigation of this satellite zone of the Norlartic deposit is part of our goal to develop the huge potential of the Marban Block. The results to date indicate that the North zone as well as the Norlartic and Kierens deposits may be amendable to open pit mining, as widths and grades are similar to the Marban deposit which has been modeled for open pit extraction".

The North zone was drilled between December 7th, 2012 and February 21st, 2013 with one drill. Drilling comprised 4,394.6 meters in 18 holes (one an extension of a 2006 hole). The campaign then continued on the Kierens deposit which was completed March 22nd, 2013. This program utilized up to four drills operating on ice bridges. Results from this program will be reported when received and compiled.

This Marban Block drilling is part of the $1.6 million program funded by NioGold. In the event of Aurizon's decision to proceed with the Phase III program, Aurizon will immediately reimburse Niogold for the costs of the exploration program and such amount will then be applied to Aurizon's earn-in requirement. Aurizon has $9.0 million of spending commitments remaining on the project as part of the Phase III program.

Aurizon Option

Aurizon can earn up to a 65% interest the Marban Block property under the terms of an option and joint venture agreement dated July 5, 2010, between NioGold and Aurizon. The initial 50% interest can be earned by incurring expenditures of $20 million over three years, completing an updated NI 43-101 compliant mineral resource estimate, and by making a resource payment for 50% of the total gold ounces defined by the mineral resource estimate. NioGold remains the project operator during the initial earn-in period (see news release dated July 6, 2010).

Technical Info, QA/QC and Qualified Persons

Reported intervals are in core lengths but are anticipated to approximate true width, except where structural complexities occur, as the holes were drilled near perpendicular to the principal local structural orientation.

Diamond drill holes were drilled with NQ-size core in order to obtain larger sample volumes of the mineralised zones, except for holes that traversed underground workings which were completed using BQ-size core. The core was sealed delivered by the drilling contractor to NioGold's facilities located at the Norlartic mine site. The core was photographed for reference, logged and mineralised sections were sawed in half. Sample lengths vary between 0.5 to 1.5 metres. Half core samples were bagged, sealed and delivered to ALS Chemex in Val-d'Or, Quebec, which is an accredited laboratory. The remaining core is stored on site for reference. 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 field duplicates in the sample batches sent to the laboratory and a systematic re-assaying of samples returning values above 2 g/t Au by the fire-assay method using a gravimetric finish. As well, pulps grading above 0.5 g/t Au are sent to Bourlamaque Assay Laboratories Ltd. in Val-d'Or for check assaying.

The drilling program is conducted under the supervision of Yan Ducharme, M.Sc., P.Geo. (OGQ), the NioGold's Vice-president Exploration and a Qualified Person as defined by National Instrument 43-101. This news release was prepared by Mr. Ducharme.
