RETRANSMISSION: HIVE Presents Record October 2021 Production Figures, HODL 1,350 Bitcoins as of October and Appointment of Luc Ouellette as VP of our New Brunswick Data Centre Campus

Vancouver, British Columbia--(Newsfile Corp. - November 22, 2021) - HIVE Blockchain Technologies Ltd. (TSXV:HIVE) (NASDAQ:HIVE) (FSE: HBF) (the "Company" or "HIVE") is pleased to announce the production figures from the Company's global Bitcoin and Ethereum mining operations for the month of October 2021, our BTC HODL position of 1,350 coins and announcing a new team member from our local community in New Brunswick.

October 2021 Production Figures

Following a record Q2 2021 earnings report (period end September 30, 2021), HIVE is pleased to announce its October 2021 production figures. The Company notes it currently has:

• US$23.4M Revenue
• 234 BTC Produced
• 2,591 ETH Produced

Frank Holmes, Executive Chairman of HIVE stated, "We are proud of the growth and operational excellence exhibited from our global operations, which has HIVE generating US$280M in annual revenue on a run-rate basis using October figures, or approximately C$350M."

Aydin Kilic, President & COO of HIVE noted, "We would like the investing public and crypto enthusiasts to understand the financial relationship between BTC and ETH mining. For example, currently 1,000 GH/s of ETH mining is equivalent in daily revenue from value of coins produced to approximately 215 PH/s of Bitcoin mining, using daily averages from the month of October. The Company believes it is in a unique position of having a large BTC and ETH mining footprint to provide investors a valuable value proposition. Mr Kilic continued, "Similarly, where one can equate hashrate on a revenue basis between BTC and ETH, you can also equate the value of the coins on a daily basis, as such the 2,591 ETH that HIVE produced is approximately equal in value to 171 BTC, in addition to the pure 234 BTC produced from our BTC operations."

The Company's total Bitcoin equivalent production in October 2021 was:

405 BTC Equivalent Produced
13.1 BTC Equivalent per day average Produced

BTC Coin Inventory (HODL)

On October 31, 2021 HIVE was Holder of 1,350 mined Bitcoin coins and has been banking them in secure wallets. Our continued strategy is one to continue holding coins, as we feel that it will benefit our shareholders.

This HODL strategy continues to led to the strengthening of our balance sheet and liquidity each and every month as we add to our BTC HODL position.

Appointment of Luc Ouellette as Vice President of New Brunswick Operations

Mr. Luc Ouellette has been in the IT services sector for many years and is a fixture of the local community in New Brunswick where HIVE's state of the art 70MW data center campus is being constructed, which operates on green energy. Mr. Holmes noted, "We are pleased to welcome Mr. Ouellette to the HIVE family, as he has been an integral part of our operations in New Brunswick as a contractor since we acquired this site earlier this year. In addition to being 100% green energy focussed, we believe it is important to recognize talent in the communities where we invest, and we look forward to Luc growing with us as we expand our facility in New Brunswick as a HIVE team member."

Currently HIVE's New Brunswick facility is operating at 30MW of power capacity and generating approximately 650 PH/s of Bitcoin mining capacity. In December 2021 the Company expects the next 20MW phase of this campus to be complete, for which HIVE will have ASIC hardware ready to be installed immediately adding 500 PH/s of Bitcoin mining capacity.

Furthermore, the Company expects that the subsequent 20MW expansion phase will be completed in Q1 of calendar 2022, which will add an additional 500 PH/s of Bitcoin mining capacity and bring the campus to 70MW of total operating infrastructure. HIVE has ASIC hardware secured on delivery such that upon completion of the 70MW New Brunswick campus, this site will produce over 1.6 Exahash of Bitcoin mining capacity, which Mr. Ouellette will directly oversee the day-to-day operations of.

Mr. Kilic stated, "We are excited to have Mr. Ouellette oversee the on-site operation of what will be one of Canada's largest single-site crypto mining campuses. I had the pleasure of meeting Luc when I travelled to the HIVE New Brunswick site earlier this year and was very impressed by his professionalism and resourcefulness." Mr. Ouellette, a local resident in the community, will manage the logistics and installations of all incoming ASIC hardware, in addition to on-going maintenance and repairs to ensure optimal hashing uptime, as well will be HIVE's regional representative in New Brunswick.
