Au Seeker I did a multi-word combination search and finally found it. it wasnt easy LOL
didnt have time to read the whole thread. I thought I posted here about the lightning electrolysis theory
but it took a few searches to find it. I was beginning to think I posted it somewhere else. anyway
look at page #6 post #14

So I moved over here so as not to further hi-jack the other thread as we seemed to get a bit off subject.

The hypothesis I presented on the Rye Patch thread stemmed from an idea I had way back when I was going to ASU for chemistry.

The professor was talking about something, probably important, and I started thinking about ways to store energy from lightning strikes.  I know people have attempted things like this using electronics and capacitors and the like.  The unpredictable nature and the huge surge of current are most likely why this isn't being done on a commercial scale, if at all.

My thought was if you could create a pond (or several) with a big lightning rod sticking up out of the middle. Then fill the pond with a  chemical solution ( of unknown composition, but highly engineered) and wait. LOL    :Just_Cuz_06:

I was thinking that the extreme energy of the lightning strike would trigger or force a chemical reaction and create a substance or 'crystals' of some kind.  The substance could be harvested from the pond and used as 'fuel'.  It (the idea) was a way to skip photosynthesis and take raw energy and store it in chemical bonds and then later release it in a way similar to extracting energy from hydrocarbons.  I daydreamed about this kind of stuff on and off, and over time the cobwebs grew on it and life went on.  Obviously, if it's possible, it's pretty high level stuff and I never worked on it or even wrote anything down.  Long story short, I didn't end up with degree either...    but I did meet my future wife.   :yesss:

Luke/Bob, I did re-read the thread albeit very quickly since I daily read every post shortly after they are posted as being part of the staff here at Nuggetshooter, I remember reading that post last night and just look at it again the reference to lightning is in the last sentence and I missed it:tisk-tisk:, I guess I need to retake that speed-reading course i took back in my youth!!:old:

I must be getting old, that reference wasn't the only one I missed, I just found where Bob mentioned lightning again on page 9, 16th post down the page and it also is in reference to electrolysis and volcanoes.

I reiterate that all newbies and those that don't get out much looking for gold to read the entire thread, as it will definitely help in your search for gold!!

I see your point but seriously I dont have the time or patience to wait for lightning. :Just_Cuz_06:and considering as I recall the temps of lightning at the point of impact are around 50,000 degrees.
I think it would be total vaporization instantly unless contained in the ground or some type of vessel. I've been toying with a similar idea for some time. the problem Is, when is not enough to much. :arrowheadsmiley::D
You can vaporize gold. not unlike mercury for example.
Does it disappear? No. just overheats, vaporizes, then condensates and falls back to earth in the form of small droplets.remember what I said. round and round. back into the cycle again, redepositing again.
some times by different means, redepositing somewhere else.
back into the oceans and creeks back into the water tables.back into the tectonic plate shuffle just looking for another place to precipitate by different processes.

Here is a link that goes into a lot of detail on how gold bearing fluids are released through the crust ... etc.   Saw it on another site and thought it might be of interest to some.

Skip thanks for the addition of this video. Ive seen it several times.but I do have a problem with it because,
in my opinion in this video they tend to blend primary and secondary gold deposits together.

and that may be confusing to some. And in my opinion they are not the same type of deposits. not even from the same time period in earths evolution.
I dont have a problem with primary gold deposits.,
They produced most of the largest gold deposits that we have found so far. :thumbsupanim JMO AzNuggetBob

Bob, 

What about post Tertiary age enrichment? I have found veins the old timers worked that completely occurred in volcanic rock from that age. One I'm aware of is a seam in either Rhyolite or Andesite porphyry and it was pretty rich. There are couple of others too. I have seen veins in the LSD area that run right through contact zones of schist and the newer volcanic rocks without alteration. This suggests at least some of the deposits occurred after the volcanic events...possibly directly after, while there was still enough latent heat to drive deformation and faulting. Is that possible? If so, it suggests there may be new deposits forming anywhere there is enough ground movement and proper chemistry.

The Earth Never Stops.  Gold is still being Disiminated to new deposits all the time.     I wonder what's going on under the Hot Springs we have all over New Mexico ?

That's an interesting article. I vaguely remember reading about black smokers many years ago, but never even considered is application to precious metal deposits on land. The more I learn...the more I realize how ignorant I am. Fascinating stuff!

I got a copy of Mr. Straight's advanced hardrock prospecting from Bill yesterday( thanks Bill!) 

I read it cover to cover in a couple hours. I haven't mentally processed all the info in it yet, but it opened my eyes to some misconceptions that I held. It also explains the numerous small digs in the LSD area that are rarely very deep. I have been beeping those when I stumble across them. I haven't found anything valuable near them yet, but I will keep at it. 

So here is a question for anyone familiar with this area. What did the old timers look for in a vein? I mean what were the key indicators that a particular vein might carry gold? I'm sure visible gold was a good clue :200:, but there had to something else that would make a prospector of yesteryear stop and sample a vein. There seem to be thousands of fissure veins here and most of them don't carry squat.

Many of the small rich surface pockets in the eastern area were located by the old timers and mined out. Many others have since eroded out into small placers and that leads me to believe they were all formed
in a short amount of geologic time, around the same time period. It all seems to be related to the volcanic activity in that area possibly from a single event or several events happening very close together.
There are several different types and groups of Volcanoes in Az. And vary in age. some produce free gold as secondary deposits, some don't. It may be that the temps of the eastern San Domingo (LSD) deposits were much hotter and that allowed them to reach the surface before precipitating from boiling solutions and gases.
I have found many smaller gold speci pieces and a few good sized ones they tossed out in the throw out piles of their digs with a metal detector.
What I look for in that area is high temp. Mineral staining and lots of vugs in the veins and stringers, or even a small area in general.
I have also found small placers below these surface pockets that the old timers never placered. Possibly because they were small and not significant enough for them to placer or they just missed them, but they are great for detecting.

Thank you Bob,

I have been concentrating on the right stuff it seems. I'm thinking you probably have already cleaned out most of the digs I've found! :head:

 

 

 

Dave As I'm sure you know, Ya cant find them all.

that's why its on my "Top ten places in Az., That just keep giving up the gold" List. :thumbsupanim

The area is quite large. Lots of places for gold to hide. 

It has not been productive yet,  but I've seen some beautiful country hoofing it around the ridgetops and secret washes hidden behind other ridges. I've come across numerous old digs that are only a few feet deep, caved in shafts and cartridges of the old timers that haven't been made in over 100 years. I'm working on wearing out my second pair of Vibram soles! One day I will stumble onto a remote hillside and find my pocket. I know the odds of finding a little gold are probably better in the reconstituted pediment placers below, but wandering the hills in search of something of my own is rewarding in its own way. Hell... the gold isn't even all that important, as I rarely sell any. Every piece I've picked up has gone to family as Christmas and birthday presents.

 

Fight the good fight Nuggetshooters...and

MERRY CHRISTMAS :4chsmu1:

Best of luck to you Dave. I've also seen some small speci and large chunks of gold come out of there with a very light green quartz. Almost a very light jade green. AzNuggetBob

I agree Dave You can hunt the lower alluvial or go after the hard rock sources. Ive seen 10 oz.chunks come out the tailings piles.I prefer to hunt up high. :brows: AzNuggetBob

When I was in high school, my Dad was the comptroller for a drilling company based out of Anchorage. They did projects all over Alaska. I can blame my fascination on hardrock gold on that. I remember the guys on Dad's crew panning drill mud in rich core holes. I have seen some gorgeous core samples brought up from deep in the earth. 

I remember one in particular that just blew my mind. It was a series of cores done on a deposit in the Fairbanks area. There was a vein almost two feet thick they located during drilling that assayed over 200 oz/ton. It as all free gold in blue quartz. Absolutely stunning!:WOW:  My Dad has a small section of one of those cores given to him by the project Geologist. I remember the holes being hard to drill through the gold bearing material...all the gold would gum up the drill head!!!

I don't remember my point in all this rambling. 

 

Oh yeah! .... hardrock gold is awesome! :shhhhh:

So true,There is a lot more gold still in the ground than out of it. AzNuggetBob

Dave I'll tell ya I worked on core drilling rig back in the late 80's. It was a small three inch hydraulic rotary rig. I was new at core drilling but I'll tell you this was an adventure.
I started out as a laborer twisting,slamming and pulling pipe, pulling it back up and sending it down one length at a time. But it is the best way to know what's down there.
But I  have to say core drilling is the way to go if you want to sink some money into a larger scale prospect hole.
Anyway on my adventure all the roads up to the pads,(drill sites) where new, dozed for the core drilling and where above old existing mine shafts, and where very steep,tight turns and very rough.
As I said I started out slamming steel and graduated to water truck driver hauling water up the hill to make drill mud. I hated slamming steel because the owner gave us a bunch of crap worn out thin walled pipe. It was already starting to split at the joints. and to make things worse dropped off a brand new load of pipe and said don't use it unless you run out of old pipe. that meaning we had to split the old pipe out at the seams/threads, down in the hole and drop it before we could trash it, and that means we had to waist all that time pulling it out of the hole and fishing the dropped pipe?. If I recall I think the limit on our rig was 300'-500'depending on the rock type and at 500' It was leaking and slinging more hydraulic fluid and mud than it was pumping and squealing and shaking like a pig stuck in a sty at feedin time.
The water truck I was driving was an accident waiting to happen.
Going down the hill wasn't to bad although I was always wondering about the brakes so I just kept my hand on the door handle.:D
Going up I had to keep my right foot on the floor shift lever that was in low range first gear
to keep it from popping out of gear and my left foot on the gas, you get used to it after awhile.
One day we had just moved to a new pad and I'm crawling up the hill and I look up at the drill rig and using the steel tower as a line up I look down and it looks like we are drilling right in line with one of the old shafts below?
so I get up the hill and I mention the the supervisor. His reply don't worry about it the geologists laid out all the drill pads, no problem. I said ok.
the next day, Im just getting up to the pad hauling another load of water and I see the steel in the rig tower drop about three feet and start shaking violently. everyone is running around trying to figure out what just happened.
Well after they finally got it shut down and pulled all the pipe we lost about three feet of pipe, core chamber and a brand new diamond bit! It swung off in the flooded mine shaft.

Ya gotta finish the story.. Wasn't there something more that happened to the rig after that too, Bob..?
You'd been talking about this at some point in the past.. I don't recall the junk pipe or water truck from then,
but seems to me there was a further oopsie with the core drill..? I might be mixing two tales tho..
