September Operational Update

Argo Blockchain plc, a global leader in cryptocurrency mining (LSE: ARB; NASDAQ: ARBK), is pleased to provide the following operational update for September 2024.

During the month of September, the Company mined 37 Bitcoin ("BTC"), or 1.2 BTC per day consistent with August 2024. BTC production was again impacted by economic curtailments during the month and low hash price.

Mining revenue in September 2024 amounted to $2.2 million down from $2.3 million in August 2024. Mining margin for the third quarter was below 10%, lower than the second quarter as a result of the lower hash price realized in the third quarter versus the second quarter, and higher power prices. As at 30 September 2024, the Company held 4 BTC equivalent.
