i here you johnny, i tested a few pans and no gold but i didnt leave a catch basin such as a pan under the bottom of the sluice long enough to even find out. I plan on rerunning the materials possibly if i set up my new highbanker next to the pile of dirt i was digging and if i find gold i will rerun the the mucked out material. I believe after running a 1/5 yard of material through keenes powersluice i was convinced that i was loosing gold for the fact after about half way through my riffles were full of black sand as arizona has the most black sand ive ever seen and therefore allowing gold to tumble down. i have solved this issue by purchasing gold hog mat a high exchange rate mat which i could have run the 1/5 yard in 10 minutes instead of 1 hr and had a way better recovery wait. I cant wait to put it to the test. Im fully confident in the new mat for Doc has done close to 100 tests on the GOLD HOG mat FULL tests which are amazing to learn how the mat works. instead of half shovel full in the highbanker time to kick it up to dumping a 5 gallon bucket in 15 seconds into the sluice
