Riot Blockchain, Inc. announced receipt and deployment of 2,500 Bitmain S19 Pro Antminers as part of the purchase agreement disclosed in October 2020. The newly received miners are currently being deployed and installation is expected to be completed over the next week. Once the S19 Pro Antminers are fully deployed, Riot will have a total of 9,540 Antminers in operation with a hash rate capacity reaching an estimated 842 petahash (“PH/s”), representing a nearly 50% increase in operational hash rate capacity. This shipment will expand the Company’s mining fleet operating at Coinmint LLC’s (“Coinmint”) facility in Massena, New York as part of a hosting relationship between the two companies. Riot has significantly reduced its energy and direct operational costs since relocating its miners to Coinmint, aided by the level of excess renewable energy available in the Massena area. The Coinmint facility draws a significant portion of its energy from hydroelectric sources and the annual average generation cost has been approximately 1.4 cents per kilowatt-hour (“kWh”) net of distribution related costs.
