I am trying to understand this. Am I right in saying that $20 a gram translates into roughly $600NZD for an OUNCE of gold?(!!) As opposed to $1800 ....................... Guess I would be located in Mugsville if I parted with it at that price. Seriously, if you get a third - less than a third - of it's value I don't see the point in gold fossicking, other than it's recreational qualities.
Hopefully I have got it grossly wrong. Hopefully you are talking specifically about 9ct gold.
Appreciate the detailed reply regardless, and I apologise for the unfiltered reply. (It's hard to type with the jaw on the floor).
