Northern Sun Temporarily Suspends Its Custom Milling Operation

Toronto, Ontario--(Newsfile Corp. - April 8, 2015) - Northern Sun Mining Corp. (TSXV: NSC) (the "Company" or "Northern Sun") today announced that it has temporarily suspended custom milling operations at the company's Redstone Mill in Timmins, Ontario. Operations were suspended on April 2, 2015 due to low ore inventory as a result of cessation of ore deliveries to the site. Since July 2014, Northern Sun has been treating ore sourced from Wallbridge Mining Company's ("Wallbridge") Broken Hammer deposit in Sudbury, Ontario.

At this time the company expects to resume treatment of ore when deliveries resume and inventories return to acceptable levels. Suspension of milling operations is expected to last several weeks.

For the period from July 1, 2014 to April 2, 2015, the Company processed approximately 190,000 tonnes of ore delivered by Wallbridge.

About Northern Sun Mining Corp.

Northern Sun owns the Redstone Mill which it has operated since 2007. The Mill was originally designed with milling capacity capable of processing 1500 tonnes per day ("tpd") of ore. The current contract with Wallbridge utilizes slightly more than half of the mills capacity or about 800 tpd of ore. The Redstone Mill is currently treating ore containing copper and precious metals. The mill produces two products; a copper concentrate which is then sent to a copper smelter and a precious metal concentrate which is processed by a precious metal refinery. Metal recoveries through the Redstone Mill have been "world class" and have exceeded original lab scale testing done in 2014.

Northern Sun also owns two former producing nickel mines and a large, prospective, land package in the Shaw Dome area, a prospective nickel belt near Timmins, Ontario.
