- Paleocene (~60 million years ago - we brreviate this to Ma) - e.g. Cerro Verde, Cuajone etc,
- Eocene-Oligocene (41-29Ma) - e.g. Chuquicamata, Escondida
- Miocene (20-7Ma) - e.g. El Teniente, La Granja, Junin.

However, if you look at each group you can see that:
- Youngest deposits are better (bigger and contain more copper), that older deposits
- Ecuador is very under-represented - just 3 little blobs.
- The biggest deposits travel south for winter (the monsters are Chilean!)
So if Sol Gold went around their project and did a bit of age dating of their intrusive rocks at each prospect, could they find some that are a bit younger (think of it as looking for Halle Berrys rather than Jane Fondas - both attractive, but one is obviously better) that could be the BFD of porphyries in Ecuador?
