I took my new Gold Rat V1.0 Highbanker out yesterday for a run in an old diverted creek on the south side of Ballarat, there was some really good colours in the flood line. I made a demo video to show you how the height of the hopper can be changed depending on the type of material (pay dirt) your running at the time.
If I'm in really soft washed flood material most often I will run a very steep angle because I don't want all the material to run through the box, I just want to wash the gold off it and into the sluice. However if I am running really muddy material then I'll lower the hopper as much as possible to slow down the fall off action and put as much pressure on the clay as i can, you will find that most often once a rock is clean it will move toward the rear of the hopper.
I didn't get a lot of colours but I wanted to show you how fine the gold is that this unit will catch, on the left the pan is about how much concentrate you'll get out of each clean out if you've run for long enough, pan on the right was the tally for the Hour run came home with some really fine gold.
