Construction of Texas Facility Begins

Argo Blockchain, a global leader in cryptocurrency mining (LSE: ARB), is pleased to announce that it has broken ground on its 200-megawatt (MW) cryptocurrency mining facility, Helios, in Dickens County, Texas, which will be powered predominantly by renewable energy. The new facility will transform Argo's mining capacity and is expected to be completed in the first half of 2022.

Kevin Brendle, Dickens County Judge in Texas, said: "Words cannot begin to explain how thrilled I am to welcome Peter and his team to Dickens County. The management team's commitment to sustainability and reinvigorating our local economy is exciting, and we look forward to the continued positive impact they will bring to our community."

With the construction of the new site, Argo will be adding up to 20 new, full-time jobs in Dickens County. The site gives Argo access to up to 800MW of electrical power.

Peter Wall, Chief Executive of Argo Blockchain, said: "Texas is a leader in renewable power generation in the United States with a flexible grid, producing some of the most competitive and most sustainable electricity rates in the nation, which is one of the many reasons why we look forward to partnering with the community in Dickens County to bring this important project to Texas. Breaking ground marks an exciting new chapter as we continue to gain greater control of our mining operations and strengthen our position as a global leader in sustainable blockchain infrastructure and mining, and we are eager to get up-and-running."
