Katherine Roe, CEO, commented:

“Our 2021 CPR reconfirms the long-term potential at Mnazi Bay, which continues to go from strength-to-strength having produced impressive volumes last year. The upwards revision in PDP reserves, after accounting for production, reflects our strong technical fundamentals as well as the hard work and ongoing investment of the Mnazi Bay JV partners.

“Our robust operations and reserves potential will enable us to continue supplying the people of Tanzania with a low-carbon, sustainable energy supply while returning capital to shareholders through our progressive dividend policy for the long-term.”
