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 …
