120 Bitcoin mined in June

TORONTO, July 6, 2023 /PRNewswire/ -- 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 and high performance computing infrastructure provider, mined 120 Bitcoin in June 2023.

• 120 Bitcoin were generated, resulting in an average production rate of approximately 4.0 Bitcoin per day
• 217 Bitcoin – 100% of Bitcoin produced in May and 70 Bitcoin produced in June – were sold during the month for proceeds totalling $7.9 million
• Total balance of Bitcoin in reserve is 9,136; 8,289 of Bitcoin in reserve is unencumbered
• Installed ASIC hashrate capacity at our Alberta facilities was 2.6 EH/s at the end of the month
• Hut 8 produced 46.2 BTC/EH in June

• In June 2023, our repair and restoration efforts at our Drumheller, Alberta site continued as the team repaired more than 3,700 hashboards throughout the month. Our focus is on re-installation and energization of the repaired miners while continuing to complete repairs on other miners.
• Earlier this month, Interior Health, the health authority for southern British Columbia signed a five-year agreement for co-location services with Hut 8 at our flagship Kelowna data centre.
• Hut 8 disclosed in an amendment to its Form S-4 Registration Statement filed in mid-June that it expects the installed self-mining capacity of Hut 8 Corp. to be 7.5 EH/s, assuming the completion of the proposed all-stock merger of equals between U.S. Data Mining Group, Inc. dba US Bitcoin Corp ("USBTC") and Hut 8 (the "Transaction"). This includes the 1.8 EH/s installed self-mining capacity at the King Mountain, Texas site which is owned by a joint venture in which USBTC has a 50% membership interest alongside a leading energy partner.
• On June 26, Hut 8 announced that it entered a US$50 million credit facility with Coinbase Credit, Inc.

"June was very productive, with key developments across our mining and high performance computing operations businesses, and progress on obtaining key regulatory approvals related to the merger with USBTC," said CEO Jaime Leverton. "We are committed to keeping that momentum going as we work diligently at closing the transaction with USBTC."
