Firm seals energy deal.
UK-listed Zoltav is 40%-owned by ArKadiy Abramovich's ARA Capital investment vehicle, its largest shareholder.
ARA is investing PS26m as part of the deal to buy the Bortovoy licence in Saratov, western Russia, which contains a number of gas fields and a processing plant.
The site produced 16.8bn cubic feet of gas last year and also has millions of barrels of oil reserves.
Zoltav's executive chairman Symon DraKe-BrocKman said: "The Bortovoy licence will become Zoltav's first producing asset. It is a well-located, cash-generative, producing field."
The company already owns the Koltogor licence in Siberia, with probable reserves of more than 70m barrels of oil, which it is looKing to develop for commercial production. It said it was continuing to review other oil and gas acquisition opportunities across the region, focused on Russia.
The deal is set to help ArKadiy follow in the footsteps of his tycoon father.
