Gatherer Card Rulings [Nov 2009]

• 10/4/2004: Sacrificing this card when the last counter is removed is part of the effect of tapping it for mana.
• 9/25/2006: If the last mining counter is removed from Gemstone Mine in some way other than activating its ability (such as Chisei, Heart of Oceans), Gemstone Mine won't be sacrificed but its ability can't be activated.
