This find dates from 2013. The island is also called Makin Island, yes, that Makin Island. The one we took in WWII.
The minerals are in deep water mud.
We also have our own large deposits on the Idaho - Montana border.
Sorry, Marcus Island not Makin.
Anyway. The island was ours until 1968.
The deposits are 160 mi south in over 5,000 meters of water.
