I have some specimens of gold in ironstone and was wondering if there is a good average SG for ironstone to use when calculating the gold content.

G'day Last Vintage, welcome to the forum

2 of the main minerals or or oxides of Iron consist of Haematite & Magnetite.
Magnetite has a specific gravity of around 5.2 & Haematite between 5.3 & 5.5.
If you're not sure as to how much Haematite or Magnetite your speci contains or consists of, go by using an average sg of the 2 oxides of say 5.4 sg & you should come pretty close to  the amount of gold contained within your speci.
