Mineral Deposits
Mineral Deposits, or Mineral Veins, are veins of ores that are very thin but very spread out. They cannot be detected without a Core Sample Drill and cannot be extracted without an Excavator. Each Mineral Deposits takes up only one chunk; this can be in any chunk though, including other dimensions and in void worlds. Most veins are not made of a single material, but made of a mix …
6 Rocks That Contain Gold (How To Tell if a Rock Has Gold In …
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.

Silver ‣ GEOLOGY HUB
2.2 Silver Minerals. Silver predominantly occurs in the form of various minerals, which are key sources of silver ore. Some of the most important silver-bearing minerals include: Argentite (Ag₂S): A sulfide mineral that forms in low-temperature hydrothermal veins. It is a primary silver ore and occurs in massive or granular forms.
mineralogy
Quartz, a silica mineral, is typically found in association with such gold and silver deposits. Where these gold-laced quartz veins are discovered and accessible, they are mined – first by placement of an adit to determine the quality of the gold-rich vein, and second by expansion of the adit into a tunnel or shaft, to recover the gold ore.

ACANTHITE/ARGENTITE (Silver Sulfide)
Acanthite is the most important silver ore next to galena.Actually there is an argument to be made that acanthite could be the most important silver ore.

But most, if not all the silver in argentiferous …
