2018 Highlights

• In November 2018, the company received all Minnesota Department of Natural Resources permits for NorthMet for which the company had applied, including the Permit to Mine, dam safety, water appropriations and public waters work permits along with Wetland Conservation Act approval;
• In October 2018, the Minnesota Pollution Control Agency transmitted revised draft air and water permits for U.S. Environmental Protection Agency review, noting that they are not open for public comment and final permit decisions are expected by the end of the year;
• In June 2018, the company and U.S. Forest Service completed the federal land exchange giving PolyMet title and control over both surface and mineral rights in and around the NorthMet ore body;
• In March 2018, the company issued an Updated Technical Report under NI 43-101 incorporating process improvements, project improvements, and environmental controls described in the Final Environmental Impact Statement and draft permits. The update also included detailed capital costs, operating costs, and economic valuations for the mine plan being permitted, as well as discussion of potential future opportunities; and
• In March 2018, the company and Glencore agreed to extend the term of outstanding debentures until March 31, 2019 or certain events, reduce the interest rate on the outstanding debentures, and make available up to $80 million in additional funding. Proceeds are being used to complete permitting, purchase wetland credits, advance detailed engineering and perform certain early works to prepare the site for construction.

Goals and objectives for the next twelve months

The permitting process is managed by the regulatory agencies and, therefore, timelines are not under PolyMet control. However, the MPCA announced that final decisions will be made by the end of the year and U.S. Army Corps of Engineers final decisions are expected to follow thereafter. Given these circumstances, PolyMet’s objectives include:

• Favorable decisions on final MPCA permits (air and water);
• Favorable decision by the USACE on the Final Record of Decision and 404 wetlands permit under the Clean Water Act;
• Completion of Project implementation plan; and
• Execution of a construction finance plan.

Note: Working capital deficit is due to the Glencore debentures being classified as current on the basis they mature on or before March 31, 2019.

At September 30, 2018, PolyMet had cash of $6.962 million compared with $6.931 million at December 31, 2017. Subsequent to quarter end, an additional $25 million was received from Glencore under the March 2018 agreement described above.

As of September 30, 2018, PolyMet had spent $131.315 million on environmental review and permitting since the NorthMet Project moved from exploration to development stage.
