I have found a couple of sub-grammers just north of the township, can't remember the name of the diggings, but as you head north it is on the right between Amherst and kangaroo gully. Can't miss 'em.
I can tell you, it was bloody hard work finding those two little nugs! I spent a couple of days there, and detected the proverbial out of that hillside!
I thought for a moment I had a patch, when I found those two nuggets within 5 metres of each other, but sadly, after gridding the area, I had to concede that they were probably just a couple of strays. I have since moved on in the search for greener pastures.
That said, it was still better than Nuggety Gully to the south, near Talbot. I couldn't even find trash there!
