The number of directors of the Company was fixed at nine and the following persons were elected as directors of the Company to hold office until the next annual general meeting. The voting results are shown below:

Joining the PolyMet board are veteran copper mining executives Dennis Bartlett and Mike Ciricillo.

Mr. Bartlett is executive director and a founding partner in Cupric Canyon Capital, a private company that is developing a large copper mine in Botswana. His mining career spans more than 40 years, where he began as a mining engineer for Phelps Dodge Mining Company in 1977. He served in various planning, operations, construction, start-up and leadership capacities at large copper mining operations in Chile, Peru, New Mexico and Arizona, eventually leading all of the company’s North and South American mining operations as senior vice president, mining operations. He later served as senior vice president, development, for Phelps Dodge and, subsequently, Freeport-McMoRan Mining Company. He had instrumental leadership roles in the expansion of the Cerro Verde copper mine in Peru, construction of a new copper mine in Safford, Arizona, and initial development of the Tenke Fungarume copper mine in Africa. Mr. Bartlett holds a bachelor’s degree in mining engineering from the University of Arizona and a Master of Business Administration from Western New Mexico University.

Mr. Ciricillo began his career at Inco Ltd. in Ontario Canada, later joining Phelps Dodge Mining Company, which was subsequently acquired by Freeport-McMoRan, where he served in various operations positions of increasing responsibility in the U.S., Chile, The Netherlands and Democratic Republic of Congo. He served as director of project development (Africa), general manager of Miami Operations (Arizona), and president of Freeport McMoRan Africa before joining Glencore in 2014 as head of copper operations in Peru. He is currently responsible for Glencore’s copper smelting and refining operations. Mr. Ciricillo holds a bachelor of engineering degree from McGill University (Quebec, Canada) and an MBA from Western New Mexico University.

“Dennis and Mike bring a level and depth of mining knowledge and experience to the PolyMet board that is without parallel,” said Jon Cherry, president and CEO. “They have operated and had executive oversight over some of the largest and most successful mining and processing operations in the world. They will be a tremendous asset as we navigate through financing, the final stages of permitting, then construction and operations of the mine.”

In other board action, PricewaterhouseCoopers LLP was re-appointed as auditors of the Company and the board is authorized to fix the remuneration to be paid to the auditors.

Following the meeting, Mr. Cherry gave a presentation on achievements of the past year and goals for the future. Key achievements include:

• All permit applications submitted as of November 2016 and subsequently are under review by the reviewing agencies;
• The U.S. Forest Service issued its Final Record of Decision on the NorthMet Project and Land Exchange in January 2017;
• All six draft permits (major) for water appropriations and both dam safety permits completed local units of government and tribal review in May and June, respectively;
• Significant progress continues to be made on draft permits with the Minnesota Department of Natural Resources and Pollution Control Agency;
• Project engineering work continues to progress commensurate with permitting.

Key objectives include completing the land exchange via administrative or Congressional process before the end of 2017; seeing draft permits out for public comment in late summer and continuing into fall with final permit decisions beginning in late 2017 and continuing through early 2018; updating the Definitive Feasibility Study and 43-101 technical report consistent with draft and final permits; advancing engineering on long-lead items to prepare for order placement; and, beginning plant rehabilitation work as allowed by permit.
