Flintstone,
Check out the article in Science Daily dated 14 January 2020 - sorry I cannot attach the link here

"No need to dig too deep to find gold!"
"Why are some porphyry deposits -- formed by magmatic fluids in volcanic arcs -- rich in copper while others primarily contain gold? In an attempt to answer this question, a researcher from the University of Geneva (UNIGE) investigated how the metals are accumulated over the time duration of a mineralizing event, looking for a correlation between the amounts of copper and gold extracted from the deposits. Not only did the researcher discover that the depth of the deposits influences the quantity of metals produced but also that over 95% of the gold is lost to the atmosphere through volcanic emissions. In short, the deeper a deposit is, the more copper there will be, while gold-rich deposits are closer to the surface. These findings, which are published in the journal Nature Communications, will provide valuable assistance to companies that mine these metals."
