6 Rocks That Contain Gold (How To Tell if a Rock Has Gold …
Quartz is classically aligned with gold.The majority of hard rock deposits found appear to occur in quartz, and gold-in-quartz has even taken on a life of its own. The gold that appears in quartz is almost universally native, meaning that it's in a metallic form contained in the crystalline quartz. It's universally considered the richest of the gold ores out there.

What this does is guide the ore to these points.
How To Identify Gold Ore (Tips and Scientific Tricks)
Determining the specimen's density is one of the first steps in recovering gold from gold ore. Knowing the density of the ore makes the process more effective. The density of gold ore varies from one type to the next. Typically, impure gold is around 16 to 18 times heavier than its associated host rock, which has a density of 2.5.
