Sources of Ore-Forming Fluids and Materials of Gold and Antimony
The ore bodies mainly occur in lamellar, quasi-lamellar and lenticular forms in the altered rocks, and are strictly controlled by anticline structure. In terms of space, elemental paragenesis-separation takes place between gold and antimony deposits, i.e. the gold deposit has antimony ore spots, and the antimony deposit has gold ore spots.

Stibnite
Treatment of Antimonial Gold Ores. P. Rohner, M. Millard, in Gold Ore Processing (Second Edition), 2016. 2 Fundamentals. Stibnite [Sb 2 S 3] is the principal antimony sulfide mineral associated with gold, although berthierite [FeSb 2 S 4] and gudmundite [FeSbS] have also been reported (Davies and Paterson, 1986).
Gold ore
Gold ore can be mined at level 40 Mining providing 65 Mining experience. After gold rocks are mined, it will take 60 seconds until it reappears. Gold ore is used to smelt gold bars.

Antimony Mobilization through Two Contrasting Gold Ore …
Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations …
