Here is my proggy:  
  
Suggestions: 
1. When depositing ore in the hopper, I think the bot should be able to walk alongside the ore, rather than have to wait till it reaches the sack. This will save time and its also more human-like than just waiting. 
2. I think the gold nugget counter is a bit off, the first inventory I got with this bot had 3 nuggets in it, and the counter only showed 1 nugget received so far. 
  
I loved the trial, but I don't have a credit card or anything to pay online with to buy the full version(I'm only 15), sorry! 
  
Thanks for the demo on this amazing script, and keep it up Czar!
