Multi-Sluice in the Field
I'm going out to the field tomorrow with the multisluice to run it in field mode. I used the hog pan last week and lugged 2 - 5 gallon buckets worth of cons back. I had to climb up the side of a bank and hike 1/4 mile through woods back to my truck. I don't want to do that again. Saving money to get a Piglet and water pump, but wanted to try the multisluice out in the field. I bought a deep cycle 12v battery. Came in a 2 pack. Each is 35 AH. I figure I will use one in the morning and the other in the afternoon. I processed 10 buckets by myself last time. I have a helper this time so I should get 30-40 buckets processed. Looking forward to carrying back 2-4 cups of material rather than 2-4 buckets!!
Hey guys, checking back in. I used the multi-sluice 3 days in the field. I found a total of 1 gram all together! 35 buckets classified down using the hog pan. I got 16 bucket of cons from that. I then concentrated it down using the multi-sluice. I did a clean out after each bucket. I worked all of that myself. I'm thinking I could run more buckets a do less clean out, but I didn't want to chance loosing gold. Maybe I was just a little paranoid about that and didn't have anything to worry about.
I set the multi-sluice up a bit different. I used a 2000GPH bilge pump, you need it. Get it as close to the water source as possible, as minimum head as possible. Angle the sluice as 13 degrees minimum. That's the only factor left to get the propositional force correct. The material wasn't active enough at 11 degrees.
I stuck with the recommended 1 bucket feed rate per 10 minutes. I used a 35Ah wheel chair deep cycle battery. Light enough to carry on and enough capacity for 3 hours of continuous operation, 18 buckets, if sticking with the 10 min per bucket feed rate.
After all of this, I'm wishing I had a Piglet! I'm in Washington, so sluices and high bankers have to be 3 sq.ft. or less including ganged equipment to operate year round with no restrictions. I'm limited to certain times of the year with high bankers 3>X<10 sq.ft. with a hydraulic mining permit.
Classifying sucks and I could have moved at least 2X the material if not more with the Piglet.
what a great report...A gram for 18 buckets is awesome!
you mentioned being inWashington State and the restrictions therein.
I too am in Washington and understand exactly what you're saying.
I prospect mostly in Skagit, Whatcom, and Snohomish counties...if you're ever up in my area we should get together on a trip!
I've been on the Sky on several occasions. Never found color like that though. There's one spot I really want to try (I know a guy that did a coupe of pans and had fabulous color!) but it is in a state park (not one that is well known or that has even 1 amenity but still it is not legal to prospect there)
Most of my time on that river has been accessed by going over Jack's Pass and I have been to the WPA Claim where the bridge is. I was with a buddy and we were testing out a new dredge design...it failed miserably btw...??♂️. His design, not mine...?
Anyway...now that I have my Stream Sluice and the new Power Pig crash box I'm all set to use it in conjunction with my home made 1.5" electric dredge nozzle. Just need a place to go where I have a chance to pull out some nice color for a change.
I have been considering joining WPA for a while now but I could never make any meetings...just too far to drive for me for my Whidbey Island.
Again...nice gold you got there!
Question for those who have run the multisluice in the field - The last 2 times I ran the multisluice in the field I did a clean out after each bucket of cons. I'd like to not ha e to do so many clean outs and just delegate the task to my wife to process cons. Do you think I could run 5-6 bucket worth of cons without doing a clean out and still maintaining a 95-98% capture rate?
Find out for yourself. Put a small tub at the end and create a fluid bed.
run 4 buckets. Weigh the gold in the mats vs the losses you pan from the tailings tub. That equation gives you the capture rate. Tub we use is rough 12" x 6" x 6". But yes... we have run 5 buckets before and had very good results as long as the feed rate was constant and not overloading.
