Wow, that's the type of thing we're trying to find for the Cue Heritage Centre. We took a few days out a week or so back searching for old relics but there's not much left in one piece.

Why is there so much gravel thrown out on a mullock?
It depends on the geology of the lead/field and depth.
A shallow lead can have a red clay decomposed/false bottom. The gravels didn't hold enough gold to bother with so only the bottom inches and the inches of clay the gravels layed on were worth it.
Skipping the highest pipeclay layer below (that also wasn't worth it but WAS gold bearing(ends up on the collar to) and decending down until you hit another gravel layer in red/grey clay.
3 ft thick, the clay to gravel ratio increases in gravels at the bottom, still baron of gold.
From there it goes straight to orange and white decomposed/oxidised slate bedrock (surface not in situ).
The gravels that lay in the deep pockets of the orange and white clay is where it is/was!
