[QUOTE="XLOOX, post: 621913, member: 16174"] I know this is no help Davent but when I was briefly in Peko-Wallsend Warrego NT in late 80s we sometimes had variable coloured bars that looked like yours, even though the colour on the strake table was golden. It was originally believed to be due to higher silver content i ie electrum but the analysis didnt really reflect that and the diagram below shows that it would have to be closer to 70% gold/30% silver to be pale. In the end I think it was put down to more impurities than the flux could handle. Good news is that if you are selling to a refiner they wont care what the bar looks like. 92 % gold is 92% gold to them.
