HALIFAX, Nova Scotia--(BUSINESS WIRE)-- Brigus Gold Corp. ("Brigus" or the "Company") (NYSE MKT: BRD; TSX: BRD) is pleased to announce a new National Instrument 43-101 ("NI 43-101") mineral resource estimate for the 147 and Contact zones on the Grey Fox property of the Black Fox Complex, which covers approximately 18 square kilometres within the Timmins Mining District. Highlights of the updated resource estimate include:

Brigus announced an initial resource estimate from Grey Fox in December 2011. The focus of the Company's exploration drilling program over the last year has been to convert Inferred ounces to Indicated ounces through systematic in-fill drilling. The new resource is based on a total of 488 holes and approximately 65,000 metres of drilling.

"We have increased the Indicated gold resource at Grey Fox from 116,710 to 480,850 ounces. This is a material increase in the Company's total Indicated resource and adds substantial value to the Black Fox Complex," said Howard Bird, Brigus Gold's Senior Vice President of Exploration. "Both the 147 and Contact zones remain open at depth and the Contact Zone remains open along strike to the north. We are excited about the near term potential to further increase this resource with on-going drilling."

Approximately 84 percent of the new resource occurs within 200 m from surface where most of the drilling has taken place and therefore has open pit mining potential. Over the next year Brigus will focus on extending and expanding both the 147 and Contact zones through systematic drilling below the 200m level and along strike to build a resource suitable for underground mining.

"Exploration drilling over the last year has converted a large portion of our Inferred gold resource to Indicated," said Wade Dawe, Brigus Gold's President and Chief Executive Officer. "We are confident that the Grey Fox property has the potential to host in excess of one million ounces of gold."

This new resource does not include results from Brigus' newly discovered Grey Fox South Zone. This multiple horizon gold zone is located approximately 400 metres to the east and running sub-parallel to the 147 Zone. Drilling is on-going at Grey Fox South and has intersected the gold mineralized trend over a 275 metre strike length. The zone remains open in all directions. Two drilling rigs are focused on defining the orientation and size of gold mineralized shoots and extending the mineralization along strike.

All three zones occur within close proximity of each other and provide Brigus with near term production growth opportunities because of their proximity to the Black Fox Mine infrastructure.

Summary of New Mineral Resource Estimate - 147 and Contact Zones

The new mineral resource estimates are reported to reflect potential open pit and underground resource values for both the 147 and Contact Zones which include calculated cut-off grades of 0.65 g/t gold for potential open pit mining and 2.63 g/t gold for potential underground mining based on parameters from the Black Fox Mine. The reported potential open pit resource was based on the resources above a plane approximately 200 m below surface level and the potential underground resource estimate was based on the remaining resources below the 200 m level plane.

Notes:
1) The effective date of this resource estimate is 14 August, 2012.
2) The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.
3) CIM definitions and guidelines were followed for Mineral Resources.
4) The resource was estimated using version Gemcom GEMS 6.4.1 . The database used for the estimate comprised diamond drill core composites and assays. All samples were collected by Company personnel. A top cut of 100 g/t was applied to assay grades prior to compositing grades for interpolation into model blocks using Ordinary Kriging and Inverse Distance Weighting Squared methods, and was based on 1.5 m composites within a 3m long x 3m wide x 3m high block model. Nearest neighbor interpolation was also used for grade estimation and validation. The ordinary kriged grade model for the Contact and 147 Zones was felt to best represent the continuity and distribution of the gold grade based on the current geological model.
5) Bulk densities were assigned to the five of the six interpreted lithological domains based on 1,162 density measurements. The average of the bulk density measurements, 2.88 t/m3, was used for all other lithologies.
6) No recoveries were applied to the estimated grades.
7) A gold price of US$1,250/oz and an exchange rate of US$1.00=C$1.00 was utilized in the gold cut-off grade calculations of 2.63 g/t for potential underground and 0.65 g/t for potential open-pit Mineral Resources. Underground and open-pit mining costs, process costs and G&A costs were estimated using experience gained from Brigus' Black Fox mine. Process recovery was assumed at 95%.

The 147 Zone mineral resource estimate is based on 266 core holes. The core area of the zone is approximately 275 m in a north-south direction dipping at approximately 80 degrees to the east. The gold mineralization primarily occurs within multiple quartz carbonate brecciated zones within bleached units of variolitic mafic volcanics and other parallel hanging wall and foot wall gold mineralized zones. The 147 Zone remains open at depth. Most recently, targeted drilling has intersected the 147 Zone at a vertical depth of approximately 435 m below surface.

The Contact Zone resource is based on 222 core holes. The gold mineral resource estimate lies within approximately 450 m of strike length and mineralization remains open along strike to the north and down dip. The Contact Zone consists of a steeply dipping mineralized fault contact between the north-south trending metasediments and mafic volcanic rocks, and includes parallel foot wall and hanging wall gold mineralized zones.

All potential future mining on the 147 and Contact zones in the Grey Fox area will be supported by the nearby Black Fox mine infrastructure. This area falls within the ongoing environmental monitoring program associated with the Black Fox mine operation. Initial hydrogeological test work and Acid Base Accounting (ABA) testing of various rock types is complete. Good progress is being made with Baseline Terrestrial Studies, Closure Plan, Mine Water Ponds, and Preliminary Review for Air Emissions and Metallurgical test work. A preliminary economic assessment ("PEA") for Grey Fox will be released in Q4, and will incorporate the new resource.
