Bitcoin Miner CleanSpark Produced 685 BTC in June, Hit 16.15 J/TH in Efficiency
CleanSpark (CLSK), a Las Vegas-based bitcoin mining company, achieved a significant milestone in June 2025, reaching 50 EH/s of mining capacity. This expansion, achieved through fully self-operated infrastructure across four U.S. states, represents a substantial increase in the company’s mining capabilities. The expansion also resulted in improved operational efficiency, with an average fleet efficiency of 16.15 joules per terahash (J/Th).
The increased capacity translated into impressive production figures. CleanSpark mined 685 BTC in June, adding to its year-to-date total of 3,968 BTC. All mined bitcoin was self-mined, contributing to a total bitcoin holding of 12,608 BTC as of the end of June. This substantial holding places CleanSpark seventh among publicly traded bitcoin holders, surpassing Tesla in ranking.
The company also implemented a robust sales strategy, selling 578.51 BTC for $61.2 million during June. This translates to an impressive average sale price of $105,860, exceeding the month’s volume-weighted average price. CEO Zach Bradford highlighted June 2025 as a “milestone month,” emphasizing the achievement of the mid-year target of 50 EH/s through entirely self-operated infrastructure.
CleanSpark’s growth trajectory extends beyond its mining operations. The company secured contracts for an additional 179 megawatts (MW) of power, bringing its total contracted capacity to 987 MW. This significant increase in power capacity is projected to support more than 10 EH/s of incremental hashrate, further bolstering CleanSpark’s mining capabilities and future production.
Furthermore, CleanSpark introduced its Digital Asset Management program, incorporating a spot sales strategy and derivative overlay. This program demonstrated initial success in June, contributing to the company’s broader focus on optimizing operations and leveraging its assets for maximum profitability. The program’s success underlines CleanSpark’s commitment to strategic financial management and maximizing returns from its bitcoin holdings. The combination of increased mining capacity, efficient operations, strategic sales, and a proactive financial management program positions CleanSpark favorably for continued growth within the cryptocurrency mining sector.
