Hut 8 Mining Announces Purchase of 12,000 New MicroBT Miners for Deployment by End of Q4 2021

TORONTO, June 30, 2021 - 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, is pleased to provide the following corporate update. All figures are in Canadian dollars unless otherwise stated.

Hut 8 has executed on a $44.373 million USD purchase of 11,090 MicroBT M30S, M30S+ and M31S miners from SuperAcme Technology (Hong Kong) Limited ("SuperAcme"), representing approximately $44/Terahash. The miners are expected to be delivered starting in October 2021 and full deployment is anticipated to be complete by December 2021. This purchase complements a smaller purchase of 863 M30S+ and M30S miners made earlier this week that is expected to be delivered and fully deployed in July, 2021.

The anticipated production capacity increase with both purchases upon full deployment is expected to be 1.081 E/H, which alongside previously announced investments, should bring Hut 8's total installed capacity to approximately 2.5 E/H. The new fleet of miners is expected to make up the first operational fleet in the Company's planned 100 MW facility being developed in partnership with Validus Power.

"We are excited to have identified this unique opportunity to purchase MicroBT equipment that will enable us to almost double our hashrate before the end of the year and substantially increase the number of Bitcoins earned on a daily basis" remarked Jaime Leverton, Chief Executive Officer of Hut 8 Mining.

The 2.5 E/H installed production capacity noted above adds to the 1,600 Gigahash anticipated from the NVIDIA cryptocurrency mining processors. Given current bitcoin network dynamics, these hashrate installations are expected to increase Hut 8's current average production from 6.5 - 7.5 Bitcoin per day, to 14 - 16 Bitcoin per day based on current economic conditions.

Bitcoin Network Difficulty Update

As recently reported, with the exodus of bitcoin network hashrate from China, latest estimates suggest a sharp reduction in network difficulty on July 2, 2021, in the range of 24% to 26%. While early in the transition, it is anticipated that the reduction in network difficulty will increase Hut 8's current average self-mined production by approximately 2 Bitcoin, from 6.5 - 7.5 Bitcoin per day, to 8.5 - 9.5 Bitcoin per day, without any direct corresponding costs. After giving effect to (i) the announced hash rate expansion above (2.5 E/H plus 1600 Gigahash, expected to be in place by the end of 2021) and (ii) the anticipated reduction in network difficulty, all else being equal, Hut 8 estimates that its average daily self-mined Bitcoin will increase to 20 - 22 Bitcoin per day.
