Picture this, you have 100 buckets of dirt, 5000 pounds. To run this pile through the Blue Bowl would seem a bit ridiculous! A life time achievement. To run this pile through the Gold Cube will take all day. First classified to 1/8th inch in 3 hours, then run through the Cube in about 2 hours. Classification would reduce the pile to about 1/3. Running this same 5000 lb pile through a highbanker would be quicker but if you are in a fine gold area, you would be blowing out fine gold after about 30 minutes of operation. You would get through the pile but have less gold. The new Gold Banker attachment will allow you to shovel right into the Gold Cube without classifying. This way you have the material handled once and will be able to have the highest retention of the gold in about 3 hours. No matter what you use to process the material, less than 2 cups for the Cube or less than a bucket for the high banker, you are going to have to clean your gold out of the cons. This is now in the range of the Blue Bowl, spiral wheel, water miller table or my favorite, the pan. Classification is key! Classify as was stated above, as many sizes as you can and work each size separately. Have fun
