Baie Comeau, High Performance Computing and Helios Updates

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

Baie-Comeau and High Performance Computing (HPC)

Argo has entered into a non-binding letter of intent ("LOI") with BE Global Development Limited ("BE"), a specialist in HPC solutions, to explore a significant expansion at the Company's owned and operated Baie-Comeau facility. This proposed expansion would involve deploying advanced HPC infrastructure, which would diversify Argo's capabilities beyond Bitcoin mining into high-performance computing, positioning the Company to serve broader computing applications in data processing, AI, and other computationally intensive tasks.

The potential HPC expansion reflects Argo's commitment to leveraging its infrastructure, driving innovation and exploring strategic growth opportunities in emerging computational markets. The HPC expansion will require the Company to incur capital expenditure at its Baie Comeau site, which is anticipated to be met by additional financing, certain aspects of which may be subject to shareholder approval. The Company will keep shareholders informed as due diligence and financing discussions progress.

Thomas Chippas, Argo's Chief Executive Officer, said: "We are pleased to explore new possibilities for our North American operations with BE. This potential move into high-performance computing underscores our strategic focus on diversifying Argo's capabilities and positioning the company at the forefront of innovative computational markets, reinforcing our commitment to sustained growth and technological leadership."

Helios

Despite ongoing discussions with Galaxy to renew the Company's current hosting agreement at Helios, the Company was informed yesterday by Galaxy that it did not intend to renew the contract beyond the current end date of 28 December 2024. Galaxy has today also announced a non-binding term sheet to host HPC at its Helios facility utilising the space and power currently dedicated to cryptoasset mining. The Company is considering its options for its mining fleet, which stands at 23,000 S19j Pros, hosted at the Helios facility.
