Looks like they were sluicing quartz rich gravels to extract the gold. Looks like it’s well travelled so I imagine the gold would have been quite fine.
The early miners sure had to do the hard yards by hand. Building dams, water races etc. When I was into reading and locating old records etc it was a treasure trove of information. On many, if not most of the old sluice workings it took capital and many months, and sometimes up to three years to get water to the ground. Before any sort of work commenced. One only has to walk an old water race to see the efforts they took. And they always got the fall. Spot on. Those were the days. Great pics Gavin. Been absent for a while on here. Often take a rest from the Internet. So good to be back.
