Unlike alluvial gold, which is found as very small flakes on river banks, goldbearing rocks have to be dug out of the ground. We want pure gold, but goldbearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals.
Shale is a finegrained sedimentary rock that forms from the compaction of silt and claysize mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." Shale is distinguished from other mudstones because it is fissile and laminated.

In, ores generation got a HUGE changes, as part of "new geology". In this guide i explain where you can find ores.
Banded iron formations (BIF) are predominantly Precambrian sedimentary rocks composed of alternating layers of ironrich minerals (commonly hematite and magnetite, but also siderite, chlorite, and grunerite) and silicarich minerals (, quartz or chert) in which the Fe content of the entire rock is at least 15 wt. %. Although typically thought of as strictly Fe resources, such as in the ...
The goldbearing ore, located in both the bedding planes of the shale and the diorite, is found in conjunction with iron oxides, pyrite, and chalcopyrite (Pardee and Schrader 1933). There was little work done in the drainage after 1904, with only 1921 production rating a mention in the annual statistics.

Gold is a raw material found in Shale and Sandstone Outcrops. It is a highly conductive metal that is used in electronics and computer manufacturing. Gold can also be found as a large resource deposit. Said large deposits are especially plentiful in the Jellyshroom Caves and Lost River. Single pieces of raw gold can be found on walls and the ground in the Inactive Lava Zone.
