Owned by Earthstone Holdings, the Nalo Baru Mine is a surface mine located in Jambi. It produced an estimated 0.027 MTPA of iron ore in 2020. The mine will operate until 2031.
As you state in our question, there a small number of hard rock deposits on smaller islands that are part of Papua New Guinea.
The only iron ore resource that occurs on the island of New Guinea are deposits of iron sands. They lie on the southern coast of PNG, around the coast of the Gulf of Papua. Currently, the main deposits are at Amazon Bay in the south east and Orokolo at the top of the gulf.
It appears the iron sands are associated with other mineral sand minerals that are zircon rich, with some deposits having titanium and others vanadium. The iron sands are composed of magnetite.
