Colombia’s foreign-led Angostura and La Colosa mining projects have been delayed due to environmental concerns. Angostura is owned by Eco Oro, formerly Greystar, a Canadian company listed on London’s Alternative Investment Market (AIM). La Colosa is owned by notorious South African-based AngloGold Ashanti, which has a listing on the London Stock Exchange.
