In the agreement, SC agrees to purchase 100% of the copper concentrate produced at the Minto Mine during the additional 4 years based on 50,000 dmt/year of concentrate production. The new extension agreement is effective as of May 16^th, 2022, and continues until the additional 200,000 dmt are produced.

"Minto Metals is pleased to announce an extension to our current relationship and offtake agreement with Sumitomo. Sumitomo has been a tremendous business partner since the restart of the Minto Mine in 2019 and we look forward to continuing this relationship and providing Sumitomo with our high-grade, quality copper concentrate for an extended period of time", stated Chris Stewart, President & CEO of Minto Metals.

"We are delighted to extend the offtake agreement with Minto Metals," stated Takeshi Ishimaru, General Manager of Non-Ferrous Raw Materials Dept., Sumitomo Corporation.
