In large mining areas/districts there are often individual mines that are accessed by more than one shaft.   This is because the mining company realized that the deposit was large, so to keep costs (bringing the ore out of the mine, travel time of miners to get to working faces, fuel, etc.) lower it made sense to sink a new shaft, which is often a considerable distance away from existing adits.   During the time that the mining is taking place on the deposit between the shafts specimens can be found in what are essentially two different mines.   If properly labeled these specimens provide a snapshot in time as to what came from each side of the deposit/mine.   Of course, after mining connects the opposite sides of the deposit then this situation may no longer be true.

Branko, you currently have information about which shaft is at a GPS coordinate.   If this information isn't perpetuated then it too may go missing over time.   As you and Uwe have proposed, putting this information in the description will save it, but to make it more prominent (and easier for researchers to find) I think that individual listings would be better.

Mindat has a scientific obligation to provide as much accurate information as possible.   We can do our best to do so, but if someone mistakenly uses this information that's not our fault.   When someone attributes a specimen to a certain mine without proof then they are the ones that are possibly/probably introducing false data into the geologic world.   It's like if someone looked at a list of meteorite locations, found a random rock at one of them, and then declared that they had found a meteorite, not that anyone would EVER do this...

Lastly, there is a precedent on Mindat for listing shafts and mines (and even adits) individually.   It would take time and effort to remove all of these.   Why do this when the information is visible and easily accessable the way that it is?

After two years, there is already another new article on new finds from Lavrion:

More new finds in the latest issue of Mineralien-Welt:
