Mister Schor. I have recently managed to adapt Oghma's boons to summon an Earth Elemental, provided I have access to quartz crystals. If you can ensure a supply of them, I may be willing to to hire on for your mining task. It would depend on the aim of the mining, the time needed, and whether I would get a chance to collect or study any unearthed artifacts or tomes of interest. We can meet to discuss this if you like.
