Aim-listed Opera Investment is eyeing May 23 as the date to cancel its admission on the London bourse – and the start of trading of newly formed spin-off Katoro Gold Mining, as the proposed sale of AltX- and Aim-listed Kibo Mining’s northern Tanzania-based gold assets is wrapped up. Opera conditionally agreed to acquire Kibo Gold, through which the Imweru and Lubando gold projects, in Tanzania, are held, from Kibo Mining for £3.66-million, settled through the issue of 61-million new ordinary shares in Opera to Kibo at 6p apiece.
