First Verified Bitcoin Mining During Commissioning

Sterling Digital plc (AQSE: ASIC), a company which uses low-cost underutilised natural gas in West Texas to power high margin digital asset production directly at the source, is pleased to announce it has recorded its first verified Bitcoin mining output during the ongoing commissioning programme.

During a controlled live-load commissioning run, the site's power-generation system supplied electricity to Sterling's compute fleet, enabling the site to record its first verified Bitcoin mining output, which has been deposited into the Company's institutional-grade custody account with Coinbase.

This represents the first end-to-end operation of Sterling's integrated infrastructure, converting contracted low-cost West Texas natural gas into on-site electricity, computing power and digital asset output.

The achievement provides operational validation of Sterling's complete gas-to-power-to-Bitcoin model under live conditions. Data gathered during the run is now being used to optimise performance across the power-generation, electrical-distribution, control and mining systems ahead of commencing continuous commercial operations.
