Some tips:
- don't bother digging down until you get 5 stones for shovel - there's a lot of stones on the surface and you should be able to get shovel + recharge on your first charge
- don't bother with digging sideways, even for that money bag early on
- once you hit the open area, doing one return after you grab exposed silver is fine, but don't bother collecting all the copper - not worth the time. Just find the deepest part and continue digging
- 600/100/100/100$ upgrades enough (even 300/30/100/100 probably), no need to upgrade more - after gold layer buy some dynamite and just keep digging down. You are not buying anything else, so you don't have to bother with having energy to return.

I'VE DONE IT IN 10 MIN THANKS

I must've got real lucky I was able to make it in 22min.
You can out run the moles and as long as they don't have sight line to you or you touch them they won't aggro to you.

Thanks!

got it in 25 minutes doing this exact strategy. You are a legend my friend.

stopped here to doff my cap in respect to you insane dudes.I got 76m and I'm proud and stopping. Do we think this is doable without any auto-clicker / prep help? (and of course insane luck )

As soon as I hit gold, I had it pretty quickly after that. Never saw any plat or diamonds
