In all honesty, not really. The Quarry mine is a great place to visit as you can get your hands on a very rare tool, but aside from that, it's quite unremarkable. The Quarry Mine offers the same drops that the Pelican Town Mine does from level forty onwards. However, you won't be progressing down the mine if you keep visiting the Quarry Mine. So once you get the Golden Scythe, there isn't really any need to return here.
