Teleport item to inventory when mined

I'm trying to make a mod with some new materials and I'm making a pickaxe that when you mine something with it, it teleports the item into your inventory (useful when your mining obsidian and it falls in lava or mining ores at bedrock level) I need help with the teleporting items part, is it possible? (btw, I'm using mcreator 1.7.3 so I can make the mod for 1.7.10)

Thanks!
