[6] Tony, along with founder and CEO of Executive Outcomes, Eeben Barlow, Deputy CEO Lafras Luitingh, and Simon Mann were the executive officers of Ibis Air, a separate partner company that was the aircraft procurement organisation that owned and operated many aircraft for EO and essentially operated as their private air force.
[14] Buckingham, the former CEO and major shareholder of Heritage has led the company through exploration finds, including the hydrocarbon system in Lake Albert, Uganda and the M’Boundi oilfield in the Republic of Congo.
Emails among the Panama Papers documents showed how Heritage Oil and Gas Ltd re-domiciled itself to avoid paying $400m (£280m) in capital gains Tax to the Ugandan government.
In the early 1990s Buckingham's military consultancy was retained by Sierra Leone and Angola to provide mercenaries to improve security conditions for foreign mining companies.
Executive Outcomes (EO) and DiamondWorks shared offices in London with Sandline International, another military consultancy.
London-headquartered, Johannesburg-based diamond exploration company DiamondWorks Ltd. (TSX: DMW) was one of three junior mining firms that traded on Canadian stock exchanges, (along with Toronto-based AmCan Minerals and Rex Diamond) that contacted Sierra Leone President Joseph Saidu Momoh in the early 1990s when the president was seeking new investors.
