Here is just a warning , Make sure you have the necessary forms to start the project. Any hand operation is fine but the use of even a small bobcat , cat or tractor falls under using mechanical recovery. This does require a permit. The permit is free of charge and must be send in to an office somewhere in BC , depending on where your claim is situated. After you recieve approval that the form has been accepted , you are free to start digging. Dont do anything outside of the rules as you stand to lose your claim or the right to work your claim ( or cell's ). I have 8 Cells myself with very nice gold in the Dease Lake area of BC.
am a Geologist by trade , so incase you need some more info , email me back anytime. Your forms may be underway for several weeks so be prepared for some delays, your working with the Govt. and they dont work 24 - 7 like you and I do. Good luck and many nuggets. Jack in Kelowna,BC.
