Corporate Swag

Rio Tinto is a $90B cap mining company. It would rank 63rd in a list of GDP by country (according to 2012 IMF data in Wikipedia), in front of Libya.

That's the Rio Tinto river in Spain, namesake of the corporation. The Rio Tinto plays host to significant mining in antiquity and present (ironically, Rio Tinto doesn't own these properties present day) and the red hue comes iron dilution into the river. The acidity of the river clocks in with a pH of 2, making it equivalent to lemon juice. Naming your mining company after the most significant downside of your industry and then rising to the top of that industry takes stones.
