Its been a long time since I have used a Highbanker, but I would estimate that my largest would be around 0.5g and it was found at Hargraves in the late 80s.
I hope river sluices count in this thread.
I got a 5gm, 80% iron stone rusty/crumbly coated nugget at the base of my bazooka gold sluice.
The top nugget in my avatar all cleaned up.
Had to figger out why the banker fell over the other day.
I was digging out this bloody bank when the shovel felt kinda heavy. 8)
So I tossed her in and next minute, The Banker toppled over breaking that damn Te***ra red Conduit I use for it's leg's.
Now I thought this was rather ,,,,, strange so I thought I had better have a look see as to what was going on.
I get out of Hospital this Friday.
(If I wish)
0.0003g
Still waiting for my first high-banker nugget. Had a mate do the "spray a rock gold and throw it in when im not looking " trick, he had me for about 1 / 10th of a second, that would have been a 100oz nugget if it was real does that count? lol
Bloke down this way reckons he is pulling 6-7gers and more recently 2-3gers from his river sluice from one hole locally. (Just saying what hes' been relaying)
6.4grammer and a 2.04grammer, did a flaming happy dance when I saw that sitting in the sluice, man I gotta work out how to put on clips on the youtuby thing.
Cheers
