Ambatovy Project Overview Sherritt acquired Dynatec’s Ambatovy nickel project in June 2007 Sherritt will operate and hold a 40% interest with partners Sumitomo (27.5%) Kores (27.5%) and SNC-Lavalin (5%) Reserve life of 27+ years Major project components: Mine Site near Moramanga 220 km pipeline to transport ore slurry Process plant near Toamasina Supporting infrastructure, including port facilities, roads, rail lines, tailings dam and power plant Refinery design capacity: 60,000 tpa LME Class 1 nickel briquettes 5,600 tpa high-grade cobalt 190,000 tpa ammonium sulphate Earth works commenced in June 2007, commissioning to start in 2009, full production in 2012 Toamasina Antananarivo MADAGASCAR

Mine Site and Pipeline Construction commenced on the 220 km pipeline which will transport the ore as slurry from the mine to the process plant Engineering has completed Hazard and Operability reviews in nearly all areas Upgrades to short term and long term erosion and sediment controls ongoing The Ore Preparation Plant site civil work is 60% complete

Processing Facility Site Upgrading of Port and transportation links to the plant site underway Employee housing being completed for occupancy in early March Over 6,000 people are employed on the project Field activities are progressing at a steady pace with over 1,500 foundation piles now in place and concrete work underway on some structures

Environment, Health & Safety and Corporate Social Responsibility Work continues to survey, salvage and trans-locate species Sedimentation and erosion control remains one of the most important activities JEAs (Job Environmental Analysis) have been established, reviewed and applied Focus on biodiversity and water management Relocation of project affected people is well advanced Health & Safety Over 8 million man-hours worked with no lost time incidents 1,922 site safety orientations have been held Corporate Social Responsibility Continuation of Special Projects (job and income creation programs, targeting communities most affected by the Project) Ambatovy project recognized by local authorities (a project that is not only about economics, but also about social aspects) Programs are being implemented to fight Malaria AM LRDI (Local Resources Development Initiative) is in operation to provide basic skills training and to help SMEs (small and medium sized enterprises) provide services to the project

4/16/2017 Summary With the addition of the Ambatovy project, Sherritt is positioned to be a pre-eminent nickel producer from laterite EXPERIENCED BOARD AND MANAGEMENT TEAM A strong management team with significant operating experience has grown Sherritt from $677 million in assets in 1995 to approximately $3.8 billion today Demonstrated a consistent ability to grow the company while exceeding performance objectives A track record of implementing strategies that build long-term stakeholder value INDUSTRY LEADER Projected to be among the world’s biggest nickel laterite mines in 2013 Among the lowest cost operators in all segments Set out to double capital assets over the next 5 years STRONG HISTORIC PERFORMANCE Revenue & EBITDA growth at CAGRs of 12% & 21%, respectively, from 2001 to 2006 A positive cash flow maintained through management of commodity down-cycles An ongoing focus on the maximization of free cash flow CONSERVATIVE FINANCIAL POSITION AND POLICIES Low financial leverage with total debt to capitalization of 19% Total debt to EBITDA of approximately 0.9x Growth projects evaluated on “bottom of cycle” commodity price economics
