Argo joins leading North American Bitcoin miners to promote energy usage transparency and accelerate sustainability initiatives worldwide

Argo Blockchain (LSE: ARB), a global leader in cryptocurrency mining, is pleased to announce that on
Sunday 23 May 2021, leading North American miners came together to discuss ESG issues related to
Bitcoin mining with Elon Musk. The meeting was organised by Michael Saylor who chaired a productive
90-minute call resulting in the group agreeing to form a Bitcoin Mining Council to collectively promote
energy transparency and improve sustainable mining practices. Alongside Argo Blockchain, companies in
attendance included: MicroStrategy, Galaxy Digital, Hut 8, Marathon, HIVE, Core Scientific, Blockcap
and Riot Blockchain.

Peter Wall, Chief Executive of Argo Blockchain, said: “Today is a good day for the planet. Sustainability
has always been at the heart of Argo’s mining operations and the newly-formed Bitcoin Mining Council is
the next logical step in fostering a sectoral shift towards renewable energy. I enjoyed speaking with Elon
Musk about these issues this weekend, and look forward to joining Michael Saylor and other leading North

American miners in working to future-proof an industry that must collectively improve sustainable mining
practices and take ESG concerns seriously.”
