It's great for breaking boulders!

Floods do incredible damage to the environment they should be Banned.

That's almost on the scale of the damage done by the DEPI on the banks of Hawthorn Ck. I'll take some pics next time I'm out there and post them here.

I don't need to be reminded that this is a public forum. ;)

I think if they ban sluicing it will be similar to dredging. Google (prosecuted for dredging australia) Very little comes up.Maybe the best way to change laws is to get caught and then fight it in court? I believe most laws in this country can't really be enforced as they are most likely invalid...

The problem with digging banks ,unlike digging holes is it''s not only is against the rules but you can't really fill it back in.

I don't think it's topaz but could easily be wrong.... A scratch test would tell you,topaz is harder than quartz.

Biotite maybe...

20xwater this is above the bedrock so it's float? If this is the case I would be testing for colors around the edge of the dig.It's good that it's decomposed as it would have shed plenty of color. Just thinking it might be still difficult to find where it came from? It would take an hour or so...

Those 6in flue brushes are good if there's a lot of rock in the mix.

Sorry liam I don't remember exactly but somewhere around 90g give or take 10...

The cutting head has a removable pilot for when you hit bedrock you can take the pilot out so as to take the sample from as close to the bedrock as possible. The shaft has lugs on it as I have a lever contraption that I can still lift it when in stiff clay.

Yeah 3m is heaps I only went that deep to see what was there, I hit a reasonably rich wash at 3m it's about .6m thick. It's too deep to warrant digging so it's not really worth testing deeper than your prepared to dig. There's shallow gold still about.

I like the look of that auger DD! GT I know that one guy can go over 7m That's right Flash! You have the right idea. With my auger I only go about 100mm at a time in stiff clay I have a lever set up if it's to hard to pull up. Rege I will see what I can do in the way of a pic,it's a pretty...

Bore size is about 90mm I think shaft is about 20mm or less, single flight. Goes about 2m deep with one extension. Pretty easy to make especially if you have a large enough hole saw to cut the flight. I haven't used mine for long time.

I guess so, it's alluvial but more like water courses or old run off areas from a very long time ago but not miocene type creek/rivers. I'm not sure if the clay colors are and indicator in other areas either, it's just a connection I've made over the last 20yrs or so around the areas I...

There's more to it than this but mottled clay red/grey or brown/grey, I use a hand auger to find it then dig a hole and test for color. If your on gold trench and back fill as you go if it's not to deep. If in doubt or have no idea of the stability of the ground timber it or leave it alone. It...

Yes.

A gx160 and p180 is around 3 times the weight,it really depends on how far you have to carry it. I couldn't carry one more than a couple of miles :|

Realistically there would have to be some coins there. Boils down to luck and determination really...
