Parque Amacayacu, where Vivian has her hideout, is a National Park in the Amazon Jungle. There are no mines (not allowed by law) and no roads leading there (no way to get there by bus as the team does). To get to Amacayu you have to take a 2 hour boat ride from Leticia, the capital city of the Amazonas Province. Also, in Colombia car plates are composed of 3 letters and 3 numbers.
When Chuck flashes on the photo of the Amacayacu mine, he sees the information "Possible hideout for Vivian Volkoff". This information couldn't have been part of Chuck's Intersect, because it's new knowledge and did not exist among the files downloaded in Chuck's brain. Also, if the CIA had that information, they should have already raided the mine, given that Vivian (and her Norseman weapon) was among their top priorities.
