Map of the Chinkuashih-Chuifen area. High-sulphidation Chinkuashih lodes in red (Penshan, the main orebody), with historic production of ~4 million ounces of gold. Chuifen low-sulphidation veins in yellow, with historic production of ~1 million ounces of gold. |

Buffalo Pit with ore outlined in yellow: the ore zone cuts across stratigraphy, probably along a local fault. Parts of the ore are breccias, some of which are sedimentary and some (such as the inset photograph) are tectonic. This is a feature of high sulphidation deposits generally, and is particularly obvious at Chinkuashih. Ore can be controlled by anything at all, from major structures to bedding, and even joints. Some is controlled by induration in shale adjacent to the dacitic intrusion. |

Penshan Central (West): a narrow ore zone of mineralisation in interbedded sandstone and shale, just south of where the Penshan structure passes out of the Penshan porphyritic dacite. The central grey area is siliceous ore (the equivalent of vuggy quartz). The pale areas are flanking alteration zones (kaolinite+alunite, sericite). |

Penshan South with ore outlined in yellow: to the top right of the photograph, where the host rock is present as interbedded shales and sandstones, ore cross-cuts in narrow zones. Towards the bottom and left of the picture, the host is a thick quartz sandstone with calcite matrix where ore blows out to a massive unit that is all mineralised. |

Third Changjen with ore outlined in yellow: the mineralised unit is a shallowly-dipping sandstone bed, which to the right is more complex, with probably structures and some massive enargite-luzonite-pyrite veins. The little cap on the top of the hill is also mineralised and is known locally as the Teapot, as from the other side it looks like a Chinese teapot. |
