Liaoshang gold deposit is attributed as pyrite-carbonate-vein-type. The main gold ore-bearing minerals are dolomite and pyrite. It has clear metallogenic differences from the Linglong-type (quartz vein-type) and Jiaojia-type (alteration rock-type) gold deposits (Liu et al., 2002, Li et al., 2017a, Sheng, 2019). In this study, we summarized the ...

Gold ore is an ore that can be obtained from gold rocks, gold deposits, and buffalkors. Gold rocks naturally generate on the Buffalkor Island,Emerald Mines, and the Diamond Mines. Mining a gold rock yields 2 - 3 gold ore per stage, resulting in a total of 4 - 6 gold ore. There's also a 10% chance the rock drops crystallized gold. Gold rocks used to spawn on Wizard Island before the …
