RE:RE:Goliath is a much better buy than the three Amigos IMO KSM will use block caving, and their grade is much lower than Goldstorm. See here: https://www.wsp.com/en-ca/projects/block-caving-reaches-deeper-deposits-at-ksm

Keep watching; as the deposit expands to the north (into the mountain), which I think may be good from a mining economics perspective.
