Taking bets on how far he gets before he gives up/just usds one.

Real response:
My quick math shows, if you use the Island mines, and don't be lazy and sell them to shrimps, it should only take you 2450 TNT. Selling them to shrimps on the other hand will require 2630 TNT. Doing the first option (given your current mining level) should put you at level 43 mining, so refining those rocks would inevitably take less time than mining an additional 180 TNT. (Just saying, easier isn't always easier)

I've seen a couple people do this before, and even helped some of them. I don't know how hard you're willing to no life it, but based off previous endeavors/examples this could be completed in 10 days or less.

Just thought this would be helpful, seeing as your 'original plan' would only require 3030 TNT and you set out to mine 500 more lol.
