Hi all,
Has anyone tried detecting the walls (and floors) of old alluvial mine tunnels?
I have a couple on my property but as yet havent done anything with them; being an old dredger have just continued with what I am experienced at.
Any suggestions as to which detector to try?
A Minelab Gold Monster, A minelab Equinox 800 with 6" coil or a Fisher Gold Bug 2

years ago i tried detecting one of those tunnels in the lyell , no gold but scared the crap out of me , ps i know how to turn a detector on thats where it stops
It wasn’t that river diversion tunnel was it. Check out this footage starting just before the 16 minute mark.
I got talking to a bloke who had abseiled down some mine shafts at Lyell & he reckoned he detected gold in the quartz in the shaft walls.

hi yes it definately was that tunnel , all these years i thought the old timers must have been following a gold seam , and your telling me it was a diversion tunnel lol , no wonder i didnt find anything
I have detected in a few tunnels into alluvial terraces. Only one was successful. Found 11g in a crevice. With a fisher gold bug
Hi Matt,
I think you know where I am, so Im hopeful of sucess…thats what keeps us going, right?
Good on you for your “lifestyle” change. I left mine 50 years too late, but Im enjoying it and get encouraged by Show & Tell.
Yea you should turn up something. Good luck! I’m certainly enjoying the lifestyle change!
Hi team,
Pulled gold out of a tunnel last week…half a dozen small bits mucking around.
Best bit was this still sitting in the wall…wine bottle top with candle inside. Tunnel is 1880’s
Had a mate find 32 ounces in 2 hours a couple of years ago with gold monster in an old shaft. Fragment of a vane they missed. Another two days to clean it up.
Interesting. Was it a shaft, vertical, or a mine drive, horizontal tunnel. In saying a vain that would indicate gold in quartz or was it alluvial? Any photos you can share? Cheers.

I detected the tunnels in the Bannockburn sluicings with a minelab Pi, with no success, a VLF machine would be the go probably
I did the same with my Equinox 800 with the small coil. Found a tiny bit with rock mixed with it after lots of swinging. Outside the tunnels was a sea of assorted lead projectile fragments and cartridge caps, soul destroying 
Where are you located?
Top of the South.
Have done both tunnels which was initially exciting, the first one was through solid rock for 55 metres then climbed a bit above the bedrock into alluvial stuff. Immediately after that a massive cave-in. Few specks panned out of the alluvial, but not worth the labour!
Second one was through 18 metres of overburden, then again, caved in.
Diddly squat return, nothing with the dectectors inside the tunnels.
The worst thing is all the anticipation is dashed, dreams of a Big Strike dissapated and now its back to same old in the river.
I know someone that found an overlooked vain fair to say they put there feet up for a year
does anyone here kno the guy that did the lyell river you tube video. quite an interesting clip but i see he hasnt put any more up for 3 or 4 years.
Why do you ask?
JW
because i like his videos
Hi Ross it’s Karl here, I would love to dig a big hole in that paddock one day, I often think about that channel
