Hello everybody, on my island I have a double, yes double NPC mine! i have also made vast tunnels myself. i have personally pulled out over 100 diamonds and countless obsidian, gold, iron, redstone.
If anyone is interested in mining, please come. you can keep 100% of what is mined, being gold, diamonds, random chests, anything. I will even supply food, torches, and pickaxes. The only thing I wish for in return is at least 50% of the cobblestone and 25% of the coal mined; all else is yours!
If you wish to come, PM me your In-Game-Name and I will send you the Coords.
