Riot Blockchain (RIOT) Mined 421 BTC in June 2022

Riot Blockchain, Inc. (NASDAQ: RIOT) announces production and operations update for June 2022.

Bitcoin Production and Operations Updates

· In June 2022, Riot produced 421 BTC, an increase of approximately 73%, as compared to June 2021 production of 243 BTC.· As of June 30, 2022, Riot held approximately 6,654 BTC, all produced by the Company’s self-mining operations.· In June 2022, Riot sold 300 Bitcoin, generating net proceeds of approximately $6.2 million.· Riot currently has a deployed fleet of 42,455 miners, with a hash rate capacity of 4.4 exahash per second (“EH/s”).

"We are pleased to report that during the month of June, we achieved full operation of all 23,000 S19 series miners in the first immersion-cooled building at our Whinstone Facility, Building F,” said Jason Les, CEO of Riot. “We initially conceived of plans for this immersion-cooled building just twelve months ago, and we are proud of our demonstrated ability to fully execute on our plans on such a rapid timeline. Our Whinstone Facility expansion project now continues on to our second immersion-cooled building, Building G, where the initial miners are deployed and hashing.

“Additionally in June, we began our annual participation in ERCOT’s Four Coincident Peak (“4CP”) program in which we curtail our energy consumption when called on by ERCOT during the four summer months of peak energy demand in Texas. As part of our participation in the 4CP program, in June we curtailed our energy consumption for a total of 8,648 megawatt hours.

“While participation in grid programs like 4CP impacts our Bitcoin production, we view this as an important part of our partnership-driven approach with ERCOT and our commitment to being a good corporate citizen in our communities. Participation in the 4CP program also reduces Riot’s energy costs in the proceeding year.”

Mining Deployment and Shipment Update

As part of its vertical-integration strategy and to lower its operating expenses, Riot announces that it has begun transitioning all of its miners hosted at Coinmint LLC’s (“Coinmint”) Massena, NY facility. The transition will consist of both a relocation of miners to the Company’s Whinstone Facility and by way of a miner swap agreement which Riot has entered into with another Bitcoin mining counterparty. This initiative is underway and approximately 5,700 miners are currently offline, and temporarily not counted in the deployed fleet figure, as they are in the process of being redeployed. It is expected that the Company will ship the balance of its S19 miner fleet presently at Coinmint to Riot’s Whinstone Facility in July.

As a result of this relocation of miners, the Company expects to further reduce its cost of production through lower power costs and by eliminating all third-party hosting fees on its hosted mining fleet.

Since its last monthly update, Riot received an additional 1,273 new S19j Pros, deployed 4,676 S19j Pros in its immersion-cooled buildings with an additional 6,324 miners staged for deployment. Additionally, shipments of 6,333 S19j Pros have been initiated out of Bitmain and are expected to be received during July 2022. Upon deployment of the staged miners, the Company expects to have a total of 48,779 miners deployed with a hash rate capacity of approximately 5.0 EH/s.

Infrastructure Update

Throughout June, progress continued on Riot’s 400 megawatt (“MW”) infrastructure expansion project at the Whinstone Facility in Rockdale, Texas. Air-cooled Buildings D and E are advancing towards completion, with electrical work continuing in Building D and installation of its intake louvres underway. The installation of the roof on Building E is now complete and progress has been made on its indoor switchboards.

As previously reported, Riot’s first immersion-cooled building, Building F, is now complete and operational. In the Company’s second immersion-cooled building, Building G, electrical work is advancing on medium and low voltage switch gear, and initial miner deployments have begun.

Estimated Hash Rate Growth

By January 2023, Riot anticipates a total self-mining hash rate capacity of 12.5 EH/s, assuming full deployment of approximately 115,450 Antminer ASICs, but excluding any potential incremental productivity gains from the Company’s utilization of 200 MW of immersion-cooling infrastructure. Substantially all of Company’s self-mining fleet will consist of the latest generation S19 series miner model. In addition to the Company’s self-mining operations, Riot hosts approximately 200 MW of institutional Bitcoin mining clients.
