Gold-rich pyrite formed by dissolution of dolomite and sulfidation of its contained Fe. Where dissolution and replacement were complete, ore-stage pyrite and other insoluble minerals were all that remained. Locally, these minerals accumulated as internal sediments in dissolution cavities to form ore with gold grades >400 g/t.
It may be mostly or completely buried in the older, cold crust – and there it slowly cools underground to crystalize into a granite. The slower it cools, the bigger the crystal size of the individual grains in the …
Gold Ore is an early game ore which spawns in the Underground and Cavern layers.

An ore[1][2][3] is a feature consisting of a natural deposit of ores or other blocks in the ground. The ore feature has two types: ore blobs and scatter ores. An ore blob is an ellipsoidal cluster of blocks.

This is due to the relative grade and, therefore, value of the extracted ore. For instance, in 2022, the average gross revenue from one tonne of ore in open-pit gold mines was $55.92 compared to $38.92 from open-pit copper operations. Hence, extracting greater quantities of waste to reach gold ore was more economically viable than copper …
