Centrefire Project

The ~2,500-hectare Centrefire Cu-Au Project is located in the Wabigoon Greenstone Belt in Northwestern Ontario, ~40 kilometers northeast of Dryden and ~35 kilometers southwest of Sioux Lookout. It has been minimally explored in the past with 10 short (<100m vertical depth) drill holes, 5 surface trenches, continuous chip sampling over multi-meter intervals and geophysics, both surface and airborne including magnetics and EM surveys. Phelps Dodge explored the area between 1968 and 1970 and discovered several stacked intervals of copper, gold, and nickel mineralization within the majority of drill holes. A Geotech airborne VTEM and magnetic survey completed in 2010 indicates 2 parallel conductors over the extent of the Project area and structural “mag-breaks” that are coincident with the known copper-gold mineralization. The project sits within a geologically favourable setting with historic surface grab sampling along the strike length of the coincident mag-high trends and VTEM conductors has returned values up to 1.9% Cu and 23.9 g/t Au1.

Besides the noteworthy historic assays and copper-dominant “Critical Metals” status, the Project is highly prospective for several deposit types including VMS, Iron-Formation-hosted, and Orogenic and also boasts an all-season ease of access, very timely turn-around-time of drilling permits when compared to other jurisdictions, and the ability to utilize the Ontario Junior Exploration Program incentives – OJEP – which can provide a grant of up to $200,000 per session. The number of known copper, gold, and base metal deposits in this area and geologic package is remarkable and very encouraging that Centrefire has the potential for a significant discovery of similar nature.

Exploration Targets

Exploration Activity

Target Style: Volcanogenic Massive Sulphide (VMS), Iron Formation, Shear Zone

Target Size: 25-50M tonnes of 1.5% Cu, 1.5 g/t Au (~1.6B lbs Cu, ~2.4M ozs Au)

Historic Work: Airborne Geophysics including magnetics and VTEM, Surface Trenching and Sampling, limited diamond Drilling.


Airborne Magnetic survey circa 2010 shows three magnetic trends across the Project area.  The breaks in the magnetic trends may be more favourable for copper and gold mineralization.

Airborne VTEM Survey Circa 2010 shows strong conductance coincident with the magnetic trends.

An Ontario Government regional airborne magnetic survey shows the extent of the magnetic high trends across the Project area and beyond.

Surface Trenching and Channel Sampling

  • 5+ historic trenches with detailed channel sampling over 150mx120m area.
  • Correlative with drill results as numerous “stacked” mineralized layers.



  • 14 short (<100m vertical depth) historic DDH’s scattered throughout the project bounds.
  • Known mineralization in drilling and outcrop extending over at least 750m SW-NE strike length and a corridor width of at least 300m with several copper-bearing rock samples being collected over 2km away along strike.
  • Multiple “stacked” mineralized layers of up to ten 10’ (3m) each with significant mineralized intervals within a 94m hole (70-3) drilled by Phelps Dodge in 1970.


Upside & Highlights

  • Extremely underexplored with at least 15km of high-magnetic strike length bearing no, to very little historic exploration.
  • Several apparent “magnetic disruptions” along strike possibly representing hydrothermal magnetic destruction or “feeder zones” replacement mineralization.
  • Hosted within a geologically favourable area of bi-modal mafic/felsic volcanism known to be a common setting for high-grade VMS and Iron-Formation Cu-Au bearing systems.
  • High-Tension power lines throughout entirety of Project length.
  • Can be drilled year-round.

Exploration Highlights

Historic Work 1970s: Operator Phelps Dodge

  • Diamond drill hole 70-3 was sampled in 3m (10 ft)lengths from surface to 84.4m (277 ft) , the hole terminated at 94.2m (309 ft). An average of 0.16% Cu was obtained in this 79.2m (260 ft) length; including a 15.2m (50 ft) section of 0.39% Cu.

Historic Work 2000s: Operator Abitibi Mining

  • Prospecting returned a high of 23.9 g/t Au with 0.78% Cu
  • channel sampling returned 12m of 1.0 g/t Au

Channel Sampling Composite Interval Highlights

Best single channel assays include up to 2.01% Cu over 1.0m and up to 3.899 g/t Au over 1.0m.

Highlight composite intervals at each strip location include:

  • 0.49% Cu and 1.731 g/t Au over 7.0m
  • 0.27% Cu and 0.531 g/t Au over 9.0m
  • 0.73% Cu and 0.827 g/t Au over 2.0m
  • 0.42% Cu and 0.281 g/t Au over 5.0m
  • 0.15% Cu and 0.888 g/t Au over 5.0m
  • 0.87% Cu and 0.138 g/t Au over 3.0m
  • 0.77% Cu and 0.073 g/t Au over 5.0m
  • 0.29% Cu and 1.189 g/t Au over 7.0m
  • 0.33% Cu and 0.427 g/t Au over 4.0m
  • 0.13% Cu and 1.327 g/t Au over 3.0m
