Hut 8 Mining Production and Operations Update

7,078 self-mined Bitcoin in reserve after 309 were generated in May

Testing complete at North Bay, Ontario site; mining began on June 2

TORONTO, June 6, 2022 - Hut 8 Mining Corp. (Nasdaq: HUT) (TSX: HUT) ("Hut 8" or "the Company"), one of North America's largest, innovation-focused digital asset mining pioneers, supporting open and decentralized systems since 2018, advanced its Bitcoin holdings in the period ending May 31 and began operations at its North Bay site on June 2.

• 309 Bitcoin were mined, resulting in an average production rate of 10 Bitcoin per day
• Our Ethereum mining - for which we receive payment in Bitcoin - generated approximately 14% of our total production at a cost of approximately $3654 per BTC
• 100% of the self-mined Bitcoin in May were deposited into custody, consistent with Hut 8's longstanding HODL strategy
• We concluded our Bitcoin yield programs during the month, bringing 100% of our reserves into custody
• Total Bitcoin balance held in reserve is 7,078 as of May 31, 2022
• Installed operating capacity was 2.64 EH/s

• Power costs continued to fluctuate throughout the month, and we limited our consumption at Drumheller when the spot price of power spiked
• Testing began at Hut 8's third mine in North Bay, Ontario in late May and began operating on 15 MW of power on June 2, adding approximately 400 PH/s to Hut 8's operating capacity
• We are continuing to add miners and increase our power supply throughout June, and anticipate that the North Bay mine will have a measurable impact on our production results going forward

"We are thrilled that our most powerful and efficient machines are now mining Bitcoin at our North Bay site," said Jaime Leverton, CEO of Hut 8. "Over the next several weeks, our team will continue to install and bring miners online in real-time, complementing production at our facilities in Medicine Hat and Drumheller."
