I would say if your in a river , run your sluice . Maybe get yourself a bigger Bazooka Gold Trap , or A Gold hog Sluice or Raptor Flair 2.0 , and work the small Gold and see how it pans out . Then you can get yourself a small crusher unit to run , and pan the material . I would keep the crushed rock and Gold material seperate save the rock dust and the Gold from it , then you can weigh them and get an idea of how much Gold your getting per ton . You should not involve anyone , that you would'nt trust with your life . Get a good assay ,done . Don't go big until your sure you have a large amout of Gold ,that will be worth the expence of recovery , you can work with small equipment and make good money perday , just working by hand and maybe look into a small Gold Dredge if you can use them in your state , they will move a lot of material with the least expence in my opinion . I have a back ground in the gravel mining industry , it's easy to spend Millions on equipment and people , Insurance , worker comp , etc etc etc. Do yourself a favor and keep it small , or you will throw your money away , and may run out of Gold to pay for your expenceses .
