Repsol YPF, a Spanish-Argentine company, has a contract to explore for oil in a
remote part of the Peruvian Amazon known as Lot 39. This region, in northern Peru, is home to at least two of the world’s last uncontacted tribes.
Repsol currently claims there is not enough evidence to prove the existence of
any uncontacted Indians in Lot 39. It says their existence is ‘extremely improbable’ and bases this claim on the ‘observations and studies available to the company to date.’
