Excavator in national park

It seems quite obvious that in Finland we are going to lose the battle against environmentalist government. They shall vote on the new mining law in autumn. Having nothing to lose (tax authorities, envy neighbours etc.), I published a video about our mining operation in Lemmenjoki National Park. Everything you see is legal, so far:

Re: Excavator in national park

That was a very nice tour and good gold in the pan! Thanks. Very clever- washing the gravel out of the bucket with the spray nozzle. Can you tell us more? How long is your season, how much gravel do you process, how long have you been at it? Too bad it looks like it will be shut down due to new regulations.

I see you use raised expanded metal over Nomad. Do you capture much gold less than 100 mesh? What is your grizzly/screen size?

Thanks,
I use a tilt bucket, which is washed by static spray nozzles. It works very well. The use of tilt bucket is something you have to test yourself until you realize the possibilities and easines to get a smooth material flow.
The screen is supported by springs (from a car) and having big rocks in almost every bucket it creates vibration by itself and stays clean. The openings in the screen are 40mmx 40mm square. Cant make any smaller as I have found 88 gram nuggets last and previous summer! They fit just barely in. As far as you dont know what you have lost, you can sleep your nights well :wink:
The miners moss and expanded metal is 4 feet long section (2 feet wide sluice) and captures about half of the gold. I am happy not to have very fine gold. Not done any scientific screening, but have a feeling that 90% of the yellow stuff is over 0.5mm.
Then there is 2m long 1 inch hungarian followed by 2m of 2inch hungarian riffles, washed once a summer.
Normal season is June-September, getting normally about 90 effective days.
I handle about 100 cubic meters per day. Not a clever system as I have to process at least three times (digging up, sluicing, and removing tailings). Any more would ruin the water quality below so it is not possible either. At the moment I have about 15 settling ponds in a row in an area of 25 x 500m. Recycling water pump produces 3000 liter per minute in a closed system.
And the best part: About 8 meters non-productive gravel on top and 1-2meters of paydirt. So we dig half a summer getting absolutely nothing and sometimes whole years income in couple of hours :wink:
Not boring to say the least.

F. digger, Is that bank run material you are diging with the back-hoe or has it been drilled an shot?

No explosives necessary.
The bedrock is rotten, so I can dig (with teeth bucket) at least one meter off. Some of these cracks are extremely rich :wink:

I guess you know you are losing lots of fine gold. Your screen is too steep and your washing of the gravel is inadequate. Your sluice looks effective though.

That really IS cute. She's got a handle on that thing. I could use a good little worker like her.

The machine in the video should look familiar to Dredger

At least he's doing the thing. Might be losing some. But then again he seemed to have some in the pan.
