In a statement on Thursday, the AIM-listed company told investors that it shared the information "to explore the potential to co-operate in respect of Tower's Namibian Blocks".
This comes after preliminary talks between the parties during the summer.
"This process is at a very early stage, and may not lead to any agreement,” said Jeremy Asher, Tower chief executive.
“However, it does provide a timely reminder that, in addition to our Cameroon appraisal and development project, the company has two extremely attractive exploration opportunities in Namibia and South Africa.”
Highlighting geology, Asher added: “Our Namibian Blocks, in which we have an 80% interest as operator, include two giant four-way dip closures in the West and four large structures in the Dolphin Graben where the 1994 Norsk Hydro well 1911/15-1 encountered three source rock intervals, and recovered oil from Albian carbonate core samples.”
He also, separately, noted that Tower’s 50% owned Algoa-Gamtoos license, in South Africa, adjoins Total's license where it made its recent 1-billion barrel Brulpadda gas-condensate discovery in the Outeniqua basin.
