For $15 dollars you get 5 -2 gallon buckets to pan. If you want to share the 5 buckets with someone, the price is $18.
The best, and most fun way to get CP gold, is with a sluice. I think 1/2 load of material is around $80, or so.
If you are adventurous, you can participate in the "Perpetual Dig" which gives you access to the placer field and load gold in the lower pit. You will learn lots about this hobby there. You'll be able to DIG 20 gallons or so of mineralized vein rock for processing. All equipment is included. The price is $100.
There will be a special for the Perpetual Dig of $50 a head in June to see if there is any interest in the notion of hardrock prospecting. If you go this weekend you will be able to get an early discount. I cleared it with the owner tonight. Tell'em Sam sent you.
Have fun.
Sam
