How to talents affect Mining?

[Axly Suregrip]

Rules for mining/tunneling in ITL. (ITL 71)

By these rules it matters if you have a pick or if you are a dwarf. But these rules do not mention needing or any advantage gained (or lost without) having the Mundane Talent of Miner. (ITL 36)

Also, the talent Architect/Builder give the ability to direct a mining operation in a siege, so does it help in any way when just tunneling without a siege? I would expect so. But how? (ITL 40)
