Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
| Tract name | Deposit type | Geology |
|---|
| Kedon | porphyry copper | Middle Devonian through Early Carboniferous volcanic and intrusive rocks composing a discontinuous continental margin arc associated with the Omolon microcontinent. |
| Kolyma | porphyry copper | Late Jurassic to Early Cretaceous volcanic and intrusive rocks composing island-arc, continental margin arc, and collisional magmatic belts associated with the Kolyma-Omolon microcontinent. |
| Pacific Margin | porphyry copper | Cretaceous through middle Tertiary volcanic and intrusive rocks representing a series of continental- and island-arc systems accreted and superimposed onto the paleomargin of northeast Asia. |
| Kamchatka-Kuril | porphyry copper | Latest Cretaceous through Quaternary volcanic and intrusive rocks representing a series of continental- and island-arc systems accreted and superimposed onto the margin of northeast Asia. |
