TeraWulf Announces Operation of Nearly 12,000 Miners at Its Lake Mariner Facility

Miner Deployments On-track to Achieve Total Year-End 2022 Targets

TeraWulf Inc. (Nasdaq: WULF) (“TeraWulf” or the “Company”), which owns and operates vertically integrated, domestic bitcoin mining facilities powered by more than 91% zero-carbon energy, announced today the successful energization of its initial batch of over 3,000 S19 XP mining machines from the previously announced agreement with Bitmain Technologies Limited (“Bitmain”) for its Lake Mariner facility in New York.

Together with the Bitmain S19 XPs recently installed, TeraWulf now has owned hashing capacity in excess of 0.67 EH/s (5,471 miners) online plus approximately 0.65 EH/s (6,500 miners) of hosted hashing capacity for a total of over 1.3 EH/s operational at Lake Mariner.

TeraWulf’s Co-Founder and CEO Paul Prager highlighted, “This is an exciting time for the Company, and we are pleased to be one of the first public mining companies to deploy Bitmain’s latest generation mining machines at scale. This represents just one of the many milestones we expect to achieve at our Lake Mariner Facility as we aggressively ramp our self-mining operations in the coming months.”

The initial batch of Bitmain S19 XPs was installed in Building 1 of its Lake Mariner facility in New York, which has a total capacity of 50 MW of digital infrastructure. Building 2 at Lake Mariner remains on track to be completed during Q4 2022 and is expected to add another 50 MW of digital infrastructure capacity resulting in total energized digital infrastructure of 110 MW by year end 2022.

“Along with Lake Mariner’s strong hash rate growth has been a commensurate increase in our grid support capabilities. During an extreme summer across energy markets, our Lake Mariner facility was called upon for nearly a dozen demand response events, highlighting our ability to offer instant, precise support when the grid needs it most,” added Nazar Khan, Co-Founder and COO of TeraWulf. “And we continue to expand the suite of ancillary services that Lake Mariner can offer to the electric market.”

As previously announced, the Nautilus Cryptomine facility in Pennsylvania, a joint venture between TeraWulf and Talen Energy Corporation, has made significant construction progress and remains on target to begin mining in Q4 2022. TeraWulf continues to target reaching 5.8 EH/s of total Company operational mining capacity in Q1 2023.
