[QUOTE="ausniper, post: 137484, member: 2658"] Hi jamie another alternative is to place a vmatt in the first 350mm.with 9mm or so expanded on top.this can be removed and checked periodically to see how you are going.not pimarily as a catchment area but to hold back the heavies a bit until the lighter material clears out.leaving less material in the mesh riffles lower down so the heavies have somewhere to drop out.you will find that alot of gold will drop in the fist section and not migrate down your highbanker very far at all.you can also decrease in mesh size as you go down the the banker.this will be classified in your matt to the differing size mesh you have.cut the moss into 3 pieces and you can check the percentage of migration you are getting.so you can make changes if need be.something like 9mm in the first bit 19mm in the second more 9mm And 5mm down the bottom.lots of different idea's all catch gold .you just need to pick what suits you best.
