I am not a holder and know nothing about gold mining but
I have always wondered who watches who in a gold mine from a
security perspective. Maybe I have watched too many movies.

Like does a mine worker have no pockets or who cleans out
the gold from the plant ? Where do they store gold on a mine site ?
Who has a key ? Who transports the gold ?

I guess they may have security or maybe the management just
takes care of it ?

I see these mines have high grades but not much production, so
not much gold to worry about anyway for you guys.

Sorry for all the questions, maybe somebody knows.
