Does cinnabar contain gold?

cinnabar, mercury sulfide (HgS), the chief ore mineral of mercury. It is commonly encountered with pyrite, marcasite, and stibnite in veins near recent volcanic rocks and in hot-springs deposits. The most important deposit is at Almadén, Spain, where it has been mined for 2,000 years.

Can you get mercury poisoning from cinnabar?
The cinnabar poisoning cases are associated with overdose, long-term uses, and improper processing such as heating, decocting, fumigating, or in combination with other drugs (31). For example, heating cinnabar resulted in mercury vapor release, and acute inhalation of mercury fumes can be fatal (32).
How is cinnabar toxic?
In cinnabar’s natural mineral and pigmented form, it’s not dangerous. However, when temperatures rise, it releases a mercury vapor which can be toxic if inhaled. “Mercury is toxic, but as long as the cinnabar isn’t heated, the mercury is locked by the sulfur, making cinnabar low in toxicity,” Ottaway explains.
