[QUOTE="Hawkear, post: 652466, member: 4728"] Probably surface appearance won't give you much to go on. You will need to do a few mineral ID tests as detailed in another thread on this forum. My opinion is not amalgam which is mercury and gold. I am not sure that lead can be alloyed with gold and certainly even if it is possible, it would not be a process that the old timers would have used anyway. Specific gravity would sort that one out as lead has a SG of 11.34. Mercury 13.53 and Gold 19.32. If you are still hoping amalgam (Mercury) you would be looking at a SG greater than 13.53. More likely something else perhaps melted by a past bushfire. My first ever detect ever was up in the old rubbish dump at Gooseberry Hill in Dunolly. It was a lump of metal which looked to my (then excited) mind the shape of a real nugget. Scratching the surface revealed the now all too familiar disappointing colour of lead. [/QUOTE]
