Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
| Tract name | Deposit type | Geology |
|---|
| Alaska Peninsula and Aleutian Islands | porphyry copper | Tertiary felsic to intermediate composition intrusions of the Alaska Peninsula and Aleutian Islands |
| 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. |
| Kazakh-Tianshan | porphyry copper | Cambrian through Silurian igneous rocks (Kipchak and Stepnyak-North Tienshan island arcs) in the western part of the Central Asian Orogenic Belt. Partly covered by the Late Paleozoic Balkash-Yili Arc. |
| Kazakh-Tarim | porphyry copper | Devonian through Early Triassic igneous rocks that include the Balkash-Yili continental-margin arc and younger rocks related to the Indosinian orogeny (collision of China with Asia) |
| Mongol-Altai | porphyry copper | A varied assemblage of Devonian through Early Permian igneous rocks primarily in Mongolia and Russian Federation that include primarily calc-alkaline continental-margin arc rocks. |
