A kibble is a special shaped bucket its a like a barrel with a handle and it's that shape so when it's drawn up the shaft or a raise it can rub on the sides and not catch and flip upside down. Most Ausie miners came from Cornwall and that's were the name was brought from, I may have German origins
That massive scar in the earth is sad. Couldn't it have been done in a more responsible manner. Filling in what is no longer producing gold. They do it differently in other places.
Ahhh the old doubling scam. I know that one as the legend of the inventor of chess. The king asked him how to thank him an he said, that the king should put one grain of rice on the first field and consecutively double that on each next. And 2 to the power of 63 turns out to be quite the big number. Seeing that as a bar scam is quite funny though and it never ceases to amaze how bad people are at 5th grade math.
