Close down whatever museums and mineral dpeartments you see fit, tis no odds to me.
Any good collectors may (or may not) do is largely outweighed by the damage caused.
Oh, the small group you refer to that is screwing it up are not mine explorers, they are the mineral collectors that attack fragile mine infrastucure with pick axes and crowbars.
Sorry Ben, still haven't convinced me there is ANY benefit to pointing mineral collectors in the direction of places with nice specimens.
How you realistically expect any of us to point people in the direction of nice sparkly bits so they can hack them out is beyond me.
Specimens collected from new workings in progress is one thing, destroying history to get them is completely another
