I am not sure... But I would suggest using a metal detector. Hope it works!
No, zinc is not a precious metal. It is a necessary industrial metal.
I have researched this topic and found that you can indeed find precious metals when using a metal detector. These metal detectors will detect items such as silver, iron, metal, gold and platinum.
GOLD!!!
Gold because it is worth alot of money and is very hard to find. Silver because it is hard to fond and also costs alot of money. All metals are precious but the rare ones are the most precious because the harder tho find the more it costs.
iradium is the precious metal element apart from platinum
is brass a precious metal
Niobium is a rare metal, good additive for stainless, but not precious - it is grey
a lump of precious metal is called at nugget if talking about gold
Uranium is not a precious metal (as Au, Ag, Pt,.....) but is a valuable metal mined in Namibia.

Yes. Gold is an extremely precious metal. It is one of the most expensive metals there is.
Platinum, a precious metal, is used in catalytic converters.
