projects overview

Northern Sun Mining Corp. is a past producer of nickel and is focused on the exploration, development and production of primarily nickel, together with lesser amounts of copper, cobalt and platinum group metals from its properties in Ontario, Canada. It owns and operates the Redstone concentrator near Timmins Ontario.

Northern Sun has three major assemblies of contiguous mining claims and leases in northern Ontario including:

  1. A 100% interest in 12,000 ha of the Shaw Dome Nickel Belt located 25 km southeast of Timmins containing three mines: the Redstone nickel mine; the McWatters nickel mine located 9.5 km east of the Redstone Mill; and the Hart nickel project located 6 km east of the Redstone Mill. The Hart project will be fully permitted upon the receipt of an acceptable filed Closure Plan together with the appropriate financial assurance. The 1,500 tonne/day Redstone concentrator ("Mill") is located at the Redstone Mine site;

  2. A 100% interest in the 6,400 ha Groves nickel copper platinum group metals (“PGM”) project 20 km southeast of Gogama;

  3. A 100% interest in the 6,300 ha McAra Lake-Ray cobalt nickel copper project about 120 km south east of Timmins;

    Exploration for Nickel is temporarily suspended pending improved Nickel prices

Redstone Mine

Redstone is located approximately 29 km south-east of Timmins, Ontario. It was previously operated by Northern Sun with active mining taking place in the Upper Zone up until 2009. Currently there are 737,000 tonnes of Inferred resources grading 1.57% Nickel and 0.03% Copper in the Lower Zone. Proven and Probable reserves are estimated at 204,000 tonnes with an average grade of 1.05% Nickel. Mill refurbishment was completed in 2013 and re-opened as a toll-milling facility in 2014.


McWatters Mine

McWatters is located approximately 9.5 km east of Northern Sun’s Redstone Mine & Mill complex. McWatters has a reserve of approximately 430,000 tonnes @ 0.70% Nickel.  Ore from the McWatters mine was determined to contain asbestos in 2012 leading to the suspension of operations and closure. The McWatters Mine has been permanently closed


Hart project

The Hart nickel deposit is located approximately 6 km east of Northern Sun’s Redstone Mine & Mill complex. Hart has a reserve estimate of 1.5 million tonnes at 1.40% Nickel in the Indicated and Inferred categories combined.  


Groves project

The Groves property is located approximately 15 km south-east of Gogama, Ontario which is about 150 km from Northern Sun’s Redstone Mill. This property has a historical non-NI43-101 resource of 500,000 tonnes of 1.5% combined Nickel/Copper above the 45.7m level in two separate zones.


Croxall project

The Croxall Project is located approximately 4.5 km north-west of the Redstone Mine & Mill complex. Although minimal drilling has been done on this site, one historic drill hole from 2005 intercepted 0.63% Nickel over a drilled width of 3.34 meters. Recent drill results from the 2011 drill program confirmed the presence of nickel in this area with drill intercepts of 1.20% Nickel over 2.4 meters and 0.92% Nickel over 4.2 meters.
