I'm trying to tie down the name of a gold mine. I have limited info, based on an almost illegible inscription, but I know so little about mines. This is a long shot ...

It's definitely a gold mine, and guessing at a deep one (ie. following a 45 degree or so angle down). Based on fairly strong circumstantial evidence, it's in South Africa, probably the Transvaal. Would have been working perhaps 1900, perhaps a bit earlier or could be a couple of decades later (pure guesses here).

The name: here's the illegible bit. The first three characters are GIN. There are five more characters, but I'm not even certain these are part of one word. Could be GIN then & or S or 8 or something, then perhaps BO, then another that might be x or & or some numeral, then finally a 'g' or something else. My guess would be for one word, though that might be wrong.

Might this ring any bells?
