Barely a weekend warrior. Hard rock + placer together = a more complete sampling picture for AU.

I have heard of everything from a gold pan to a concrete tub to a sluice extension with different matting being used to check for losses from a highbanker.

What do you think is the most accurate way to check for losses from a highbanker - specifically - which type of catch device?

Pan the tailings for a spot check. If you want more than a spot check have someone, with a different machine, run some of your tailings

You can pan your tailings but any gold lost will be mixed with a lot of waste. Any samples tested there will be of much less values than your bank run material

You can set up a secondary sluice downstream of the main to check for gold but it must be of equal or greater efficiently than your main or it wont tell you much.

I would try to do a clean up of only the bottom 3 riffles of your sluice. If gold is getting all the way down there then it's probably getting all the way out too.

Good idea to test only the bottom 1/2 or 1/3 or your last sluice, Bonaro.
