     For thousands of years mineralized quartz veins and exposed ore bodies have been shedding rich float before the old-timers ever discovered them.  Due to vast amounts of weathering, many of these veins have now weathered out and formed hillside (eluvial) and stream (alluvial) deposits.  Many of the hillsides around idle rich gold mines may be dotted with gold ore and nuggets.  Today's detector technology, including the new Pulse Induction (PI) units can find pieces of gold down to the size of a match head.  With the use of a quality metal detector, prospectors can now increase gold finds by covering more area in a shorter amount of time.

    Due to a high specific gravity of gold and millions of years of erosion and concentration, gold nuggets found the lowest possible place to rest.  Most of the time, these areas were drainages, and the old-timers conducted most of their working within them.  They dug down and exposed the rich pay layers of gravel at or near bedrock.  In arid desert regions such as the Southwest, drywashers were used the most.  The old-timers processed these rich pay streaks of gravel through crude drywashers.  Due to inconsistent air flow, poor design and overloading resulted in poor recovery. Some reports say the old-timers lost more than 50% of the values they processed.

  Many of these drywasher tailing piles still contain sizable gold nuggets that can be recovered with modern day metal detectors. Many of the drywashers used half-inch minus hopper screens, so anything larger was discarded and formed coarse tailing piles.  Many of these drywasher spoil (tailing) piles are still waiting for a detectorist to find them!!

Should you ever find a nugget in a ravine or a depression, after your stop shouting and screaming in celebration, it's time to use that noggin to figure out where it came from. As you say in your post, the gold had to settle down from somewhere. This is where old survey maps are essential. Everybody wants the latest maps and that's always a good idea but the old maps will show you where topographic lines have changed. Locate where you found the nugget and look uphill. Yes. I said uphill.

Look on your map to see where the headlands - for lack of a better term - for your ravine or depression. That's where the gold came from and where you will find more. It's even better if the old map shows a change in the topographic profiles. That means a shift in the ground nearby which can mean a brand new vein has been exposed at best or a small pocket of nuggets has burbled down from the area which was eroded since the last survey map. The old geodetic survey maps are available from the US Coast and Geodetic Survey repository site. They may be available from the US government offices but I'm not sure. I'll post the URL in my next topic on this forum so as not to mess up the contractions I used in this post.

Hey GD,
Something I noticed in studing satellite images ( combo of x band and p band) is that if you zoom in on these images the resolution gets very bad. However, what really jumps out is old ravines, old river channels, old creek beds pop out. Check this out it is really amazing.So with this said this could be used as a tool to find areas where more nuggets could be found. If you uncover alot of nuggets using this idea and did not know this, just remember you heard it here.

Hello ksightler,Goldigger1950 and findoldstuff !! We pretty much know what Metal Detector is the best for finding small gold and covering large areas , and we are learning about satellite images /google maps etc... The last and only problem is how to quickly retrieve/extract the thousands of small flakes/tiny gold nuggetts in a dry desert environment ? I mentioned this several months ago on this forum . So any suggestions are very welcome !!!
Best Regards........Eugene

Hello Eugene-
I hate to answer a question with a question but I am in needle in a hay stack situation trying to think outside of the mine shaft box.  But here goes- What sets gold apart from other minerals- we know the magnetic frequency response- that leaves micro frequency- dyne levels- conductivity- there must be another property that gold gives off- I know micro frequency - what the heck are you talking about- replies that I am in store for. In a dry situation sand falls in a if you will the norm micron. I swear I am on no medication. Maybe thats the problem. HAHA

Hello findoldstuff . Everything is great !!! Thank-You for your work on the forum here !! You stated Satellites can now find Old Ravines , Old river channels , old Creek beds and automatically I thought "oh no" they are Dried up with no water , that means dry panning !! I heard you can loose more gold dry-panning than gold panning in a "water filled river" . Is that true ? So my question is , will dry panning retrieve all the Gold flakes/small gold nuggetts ? And I read the resonance of Gold was calculated at 2 MHZ [mega-hertz] not 2 khz !! .....Yes , sorry to say we are both sober and drug free on this Great forum !!!!
Best Regards............Eugene

Eugene52;

That is interesting, apparently ice has a microwave frequency resonance and so can be tracked from satellite... it stands to reason anybody could do the same with gold, from a few feet, in that case, and I think you just gave me an idea on how to it!! Thanks! now I have to go play.... lets see, where did I put that darn solder iron?   Shocked

Everything has a resonant frequency but some are tied both to the molecular structure and the shape. The rule of thumb is, the resonant frequency is only a sure thing in a substance that has a crystalline form and it must be in crystalline form. Quartz rock, for example, has no resonant frequency but quartz crystal does. Gold is the same. As a nugget, nothing. As crystalline gold, yes.

That's in nature. Pure gold in ingot form has one but that's kind of useless unless you're trying to find Fort Knox by satellite.

A cubic yard of gold bearing material will fill 300 gold pans. A fast panner can go thru this in a day and a half...maybe...if he/she is not doing the actual digging. My metal detector scans this same volume of material (for pencil eraser size gold) in about 6 seconds. Thats right SIX seconds.
