Castle Rock, CO, June 10, 2021 (GLOBE NEWSWIRE) -- Riot Blockchain, Inc. (NASDAQ: RIOT) ("Riot, Riot Blockchain or the Company"), one of the leading Nasdaq listed Bitcoin mining companies in the United States, announces its May production and operational updates, including its unaudited Bitcoin (BTC) production for May 2021 and its latest miner delivery status.

Production and Operations Updates

-- In May 2021, Riot produced 227 BTC, an increase of approximately 220% over its May 2020 production of 71 BTC. -- Year to date through May 2021, the Company produced a total of 924 BTC, an increase of approximately 101% over its pre-halving BTC production during the same 2020 period of 460 BTC. -- As of May 31, 2021, Riot held approximately 2,000 BTC, all of which were produced by its mining operations.

The Company plans to continue to provide monthly operational updates and unaudited production results through the end of 2021. These updates are intended to keep shareholders informed of Riots mining production as it continues to deploy its expanding miner fleet.

Whinstone Acquisition Completed

On May 26, 2021, Riot announced it completed its previously announced acquisition of Whinstone U.S. (Whinstone). Whinstones Bitcoin mining facility in Rockdale, TX is the largest Bitcoin mining facility in North America, as measured by its 300 MW in developed capacity. The Company announced its plans to immediately commence further development of additional capacity at Whinstone in order to rapidly bring the property to its current capacity of 750 MW. This expansion will be driven by Whinstones industry leading development team of over 100 employees.

Whinstones comprehensive energy management strategy delivers best-in-class net energy costs of approximately 2.5 cents per kWh utilizing cutting-edge technology and comprehensive analytics to deliver industry-leading low cost, reliable and responsive power.

Recent Miner Deliveries

As part of a December 2020 purchase order with Bitmain, 1,000 S19 Pro Antminers (110 TH) were shipped in late May 2021. Installation of the 1,000 miners is expected to be completed in Q2 2021, and upon full deployment of additional miners with Riots existing fleet, Riot will have a total of 23,946 Antminers in operation, utilizing approximately 76 megawatts (MW) of energy, with an estimated hash rate capacity of 2.4 exahash per second (EH/s).

These 1,000 S19 Pro Antminers will be deployed at the Whinstone facility alongside the previously announced shipment of 6,500 Antminers. Riot continues to receive miner shipments from Bitmain as scheduled.

Hash Rate Growth

By Q4 2022, Riot anticipates a total hash rate capacity of 7.7 EH/s, assuming full deployment of its anticipated fleet of approximately 81,146 Antminers acquired from Bitmain, 95% of which will be the latest generation S19 series model of miners. When fully deployed, the Companys total fleet is expected to consume approximately 257.6 MW of energy, with approximately 208 MW deployed at Riots Whinstone facility and approximately 51 MW deployed at Coinmint LLCs facility. This results in an overall hash rate efficiency of 33 joules per terahash (J/TH). This demonstrates Riots commitment to being a market leader by building one of the largest and most efficient Bitcoin mining fleets in the industry.

Sale of Coinsquare Shares

As previously announced, Riot completed the purchase transactions with Mogo Inc. (NASDAQ: MOGO) whereby Mogo cumulatively acquired 100% of the 3.4 million common shares of Coinsquare Ltd. held by Riot, in exchange for total consideration of 3.2 million shares of Mogos common stock, plus approximately $1.8 million in cash. With this transaction, Riot has now completely disposed of its equity investment in Coinsquare.
