Based on the provided information, finding mica does not always mean gold is present.
Mica is a common mineral found in many different types of rocks. However, the presence of mica alone is not a definitive indicator that gold deposits are nearby. The reference explicitly states that while mica is common, "it doesn't always mean there is gold present".
Gold is typically found in specific geological settings and associations, rather than universally with common minerals like mica. According to the information provided, gold is usually discovered:
- In quartz veins
- In association with other specific minerals, such as pyrite (often called "fool's gold") or arsenopyrite.
While mica might be present in some rocks that also contain gold, its presence is not the primary characteristic prospectors or geologists look for when searching for gold deposits. The typical indicators are the presence of quartz veins and certain sulfide minerals.
In summary, while mica is a widespread mineral and could potentially coexist with gold in a rock, its presence is not a reliable sign of gold.
