Highbanker Flare test Australia day 2015

So Ive been testing some goldhog matte configurations using the flair out system to see what fine gold we can capture whilst running seriously aggressive water through the header box and down the initial sluice.

The new spray bars are made to allow additional flow without restricting pressure so we can drench our material in the hopper. The spray bars are custom threaded 50mm bar.

I plan on incorporating either expanded metal in the flair to knock some of the velocity out of the water or i will build small wings dams to separate the water. After smoothing the water flow out with a rubber damper i was pretty happy with the spread.

Now configuration wise I ran 9.5 degrees in the aggressive Matt then 7.5 for the flare. I later tested it out running 5 degrees and as expected the riffled packed up with black sand very quickly.

overall very happy with the capture rate, the fine gold speaks volumes about it. I did several test pans form the tailing and only got 3 specks all up so i'm happy with that especially with the amount of black sand and gems we were contesting with.


Next test will be on a fine gold deposit and hopefully well see some serious results. until then here's some photos.

Gold Rat Testing Flood Line

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.
