CleanSpark's Bitcoin Mining Momentum Continues: A Look at September 2025 Performance

CleanSpark (NASDAQ: CLSK), a leading name in Bitcoin mining, has once again demonstrated its unwavering commitment to efficiency and growth, unveiling an exceptional performance update for September 2025. The company’s latest figures underscore its strategic operational excellence and a relentless pursuit of expanding its sustainable mining infrastructure.

In a month marked by consistent operational uptime and strategic deployment of new hardware, CleanSpark successfully mined an impressive 800 Bitcoin during September.

This robust production figure highlights the company's optimized facilities and its ability to capitalize on market opportunities. Reflecting their 'hodl' strategy, CleanSpark’s total Bitcoin holdings have now soared to approximately 6,500 BTC, reinforcing their long-term confidence in the digital asset.

The operational hash rate, a key indicator of a mining company's capacity, saw significant advancement, reaching an formidable 17.5 exahashes per second (EH/s) by the end of September.

This substantial increase is a direct result of ongoing infrastructure enhancements and the strategic activation of new, energy-efficient miners across their growing portfolio of sites. CleanSpark continues to lead the charge in operational efficiency, maintaining an average power efficiency of approximately 25 joules per terahash (J/TH), cementing its position as a highly competitive and sustainable miner.

Behind these impressive numbers lies CleanSpark’s aggressive and well-executed expansion strategy.

The company is making rapid progress on its new Warwick site, which is set to significantly boost its total operational capacity. The deployment of cutting-edge Antminer S21 units and other advanced hardware is proceeding as planned, with the aim of reaching an ambitious target of 20 EH/s by the close of the year.

This forward-looking approach ensures CleanSpark remains at the forefront of the industry, ready to leverage future Bitcoin halving events and market shifts.

Zach Bradford, CEO of CleanSpark, expressed his enthusiasm regarding the latest results, stating, “September was another testament to our team's dedication and our strategic vision.

We are not just mining Bitcoin; we are building a resilient, efficient, and scalable operation that consistently delivers strong results. Our continued hash rate growth and industry-leading efficiency metrics are setting us up for an even stronger finish to the year and an exciting future. We remain steadfast in our commitment to sustainable practices and creating long-term value for our shareholders.”

As CleanSpark continues to innovate and expand, the September 2025 update serves as a clear indicator of its solid trajectory in the ever-evolving Bitcoin mining landscape, solidifying its role as a key player in the digital economy.
