Nice topic. Begs the question, "How many different types of mining procedures are there? Whether the mining is done via one large chunk or many little bites, it eventually will get done. The best plans always have backup plans. Just watched a RR video where the first mining procedure used horses on rails to bring out the ore, thus the need for mechanical invention and the Brits developed the first steam engine after studying how the steamship worked, they applied it on rails. Was rathe slow and the horses all had hernias when they were done.

Happy Easter everyone!
