I wonder why all mineral deposits arefound on or beside faults or contacts, hardrock or placer? The richest gold deposits in lode or placer deposits are found where two faults or a contact and a fault meet. My theory is that all golld and metals are pushed up through these faults and fissures and deseminated in their present form and in solutions.
All the speculation that the geologists use to determine how the deposits originated are theory which I have have debated with only my observations and experience in placer mining. Open for debate.
