Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
| Tract name | Deposit type | Geology |
|---|
| Manchuride | porphyry copper | An assemblage of Jurassic and Cretaceous post-subduction volcanic and intrusive rocks in northeast China and parts of Russian Federation, Mongolia, and North Korea |
| 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. |
| Gobi-Amur | porphyry copper | Cambrian through Early Devonian igneous rocks that consist mostly of continental-margin arc rocks with some island-arc rocks at the eastern end; mostly covered by the Late Paleozoic Kazakh-Mongol Arc |
| Mongol-Sayan | porphyry copper | Cambrian through Silurian igneous rocks primarily in central and northern Mongolia and bordering parts of Russian Federation, including the Tuva-Mongol island arc and a variety of other calc-alkaline rocks. |
| Oyu Tolgoi | porphyry copper | A varied assemblage of Devonian through Triassic igneous rocks that include the Devonian Kazakh-Mongol continental-margin arc, as well as 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. |
