ScoZinc Receives Renewal of Key Operating Permit

Cooks Brook, Nova Scotia, September 12, 2017 – ScoZinc Mining Ltd. (TSX Venture: SZM)
(‘ScoZinc’ or the ‘Company’) is pleased to announce that, as anticipated, the Company has been
granted a 10-year renewal of it’s Industrial Approval Permit enabling the restart of operations at
the ScoZinc mine in central Nova Scotia. Studies are currently underway to update estimates
included in the project’s PEA which was completed in 2013 and to evaluate options to improve
the project restart potential, and are expected to be completed shortly.

With this key permit in place, the Board will review operational plans for the restart, the improving
outlook for zinc and lead prices and financial market conditions leading to a final determination
for restarting operations at ScoZinc. With a fully permitted mine with existing infrastructure in
place, the Company is confident that the potential of this asset can be realized in the current
market and, subject to the restart evaluation and financing, management believes initial
production can be achieved in 12 to 18 months.
