If you look under a x10 or x20 loupe the brown is probably host limonite that the gold occurred with.

My guess in your situation the gold is travelling downward as there is not huge water flow. The other material travels around the gold and rounds the edges. The source is  close but probably not the decomposed rock layer unless you can see quartz or similar ore.

However these are just generalizations as I dont know the ground you are in.

As far as I am aware that is exactly where Minelab came from in the first place, someone's garage. 

Yes, but that is an awful long way from where they are now. That is my point.

If it was really that easy, why does minelab spend millions on R&D, if a guy in his garage can come up with a competitive detector? If there were such garage geniuses lying around, why would they not be multimillionaires already? It is just not plausible, and IMHO frankly lacks a little humility

15 inch evo rarely leaves my 5000

Maybe, but there is gold there....and a lot of it if it is that easy to find. And that last piece looks a little chunky. That is a great sign. There will be good spots there. Figure out the ground.

Since this is log scale however this would indicate large increase in sensitivity for flat wound close to the coil (about 2 miniteslas compared to cylindrical), and the cylindrical only has a marginal incease at depth of 0.005.

It’s a pity high bankers are illegal for us to use in NSW. The material would have fed through quickly as it was all contained within gravel with next to no clay.

If you cant use a highbabnker that gold is about perfect for drywasher/blower. With no clay it should process well and pay for itself fast

If you have a truck I have a whole desert that has sand with gold in it.

the only berries I pick are the little round lead ones that I mostly keep finding. Don’t eat those!!

Nor the ones the rabbits and bighorn leave behind...

Take some soil samples home when you are out and pan them. Gold likes to hide where gold is.

The area is not known for gold. Show me any other nugget at all from there. They hypothesize gravels for the railway, but typically that is crushed rock and mine tailings, not river gravel. And lastly, how many 2 ounce nuggets are there from Wales..next to none

This story has all the highlights of a dime novel. Late to the event, broken detector, there only 5 minutes, only 6 inches down..and in an area never known to have any gold deposits

Now that's a business card

New design and material skid plates

He seems to indicate this new detector is his, or related to some company he works with? 

There was a whole video on the new patents he has got for the huge 6m coil that was discussed on this forum. I suspect he is referring to that. Hope it is something different.

Shame that patents are no longer being processed, but that is a separate topic. Can see that you would need to be careful who is allowed to prospect on your claim.

Thanks for the info

lode deposit has been discovered within the boundaries of the placer claim. In that situation the new lode claim replaces the placer claim within the lode claim's boundaries.

Just curious why you would pay to file a new claim over ground you already hold the rights to? The placer claim would allow you to prove the lode. Only reason I can see is if you are developping a subsurface mine

I believe exploration prospecting is the real future of serious detecting in the US.

Now the big question hanging over it is benefits outside of prospecting with its Target Id's, how beneficial is that going to be in parkland and beach settings, for me so far, it's looking good.

A second big question is how useful this will be in really trashy areas of the motherlode. It has potential here to do what more expensive machines cannot

Yeah, the response from those air tests on large pieces were not very deep

I presume you are using the 4500 PI because you want depth. Otherwise you would use VLF with target ID. If you want depth then the larger monos are your coils. Iron discrim doesnt work very well at depth anyway.

I just use a SwissGear 1651 City Pack. They are narrow and small to maintain mobility, but carry 3L bladder and fit my pinpointer scoop, tools, emergency equipment etc. It has been pretty comfortable on long trips, and best of all it is 40-50 USD. I also dont like big bags that carry too much (as then I take too much I dont need).

There are also coil cable ferrite snap on shields, but I dont know if they actually do anything

You keep bringing up EMI shielding, what exactly do you mean by this? what are you doing for this shielding? 

I use the shield you mention (thanks Aureous) plus Woody's emi filter. Biggest noticable effect was switching from stock battery to aftermarket lithium, and getting rid of the amplifier in the stock battery. That seemed to introduce a lot of noise.

After that I was able to run gain of 19 stabilizer 14 in most conditions, which was simply not possible before

I get the newer coils but is the amplifier that much more of an advantage?

Amplifier allows you to lower the threshold on the detector controls, but then amplify with the external amplifier. The effect of this is you can use a much lower threshold but still hear it clearly, and boost the quiet signals that were hidden by threshold to be audible. When combined with emi shielding you can also lift the stabilizer so you hear much smaller signals. The overall effect of this is much greater sensitivity to small signals. In effect you are running the dector using settings you previously could not hear. The amplifier quality is also much better than the one in the stock battery.

In my experience it allowed me to go over ground and hear deeper nuggets. But ask the australians, they all use amplifiers
