Campus to reach 300MW at full build-out
Cryptomine and HPC data center firm Cipher Mining has commenced operations at its long-planned Black Pearl Bitcoin mining site in Texas.
Cipher reported that 150MW of Bitcoin mining power was now live at the Black Pearl site, marking the completion of phase one of its development.
First announced in October 2024, the total capacity of Black Pearl is set to reach 300MW with the completion of Phase II, details of which have yet to be announced.
Bitcoin hashing power at the site is currently set at ~2.5 EH/s according to Cipher, with the rest of the forecasted ~9.6 EH/s set to be activated across the third quarter of 2025 as new mining rigs are delivered to the site.
“We’re proud to be mining bitcoin ahead of schedule at Black Pearl, following the safe and efficient delivery of a best-in-class data center in just 16 months,” said Tyler Page, CEO of Cipher Mining.
“As we continue to expand our mining footprint, the disciplined operations that underpin our positioning as one of the industry’s lowest-cost producers of Bitcoin will remain a key advantage,” Page added.
Cipher Mining’s latest operational update shows the company mined 179 Bitcoin in the month of May 2025. The company now holds a total of 966 Bitcoin.
With the Black Pearl site now live, Cipher Mining operates five separate data centers dedicated to Bitcoin mining and other HPC uses. These include a site in Odessa, Texas (207MW); a site in Alborz (40MW), and two other joint venture sites near Andrews, known as Bear (40MW) and Chief (40MW), alongside WindHQ.
In May, Cipher Mining purchased 300MW of wind power from renewable energy firm Engie, for use at its data centers in Texas. In February, the company received a $50 million investment from Japanese firm SoftBank, which gave the investor first rights to buy an undeveloped mining site near Colorado City, Texas, which could offer 300MW when fully built out.
