Hi Keith, I come from a long line (since 1932) of mediocre successful to completely failed Hard Rock miners in South Australia. My Gold is fine to very fine gold in quartz veins. Thankyou for these lessons, they are in plain language and easy to follow. Please keep up the great work and you keep it safe as well. (PS I love the shooting iron hanging off your hip)
Glad to be of help. Right now the challenge is to recover some extremely fine gold from a mine here in Mantana and I am having to learn and develop new tricks as cyanide leaching is banned in this state. It is going reasonably well so far, but we still have to define and refine the process of recovering the gold from the solution.
Great KISS principle video. Love it. My great great grandfather was a Prussian/German scientist who became the Singapore Government mineralogist and he died prospecting for Gold at Lahad Datu in North Borneo. I'm not academic so I appreciate the basic teaching method.
Fantastic explanation! I've enjoyed collecting minerals my whole life and have never considered how the minerals form or where the veins came from. Thank you
Glad to help. You could also log onto one of our Monday evening live streams and have them ask questions. That might get their interest, If you live near Helena MT, we could even give them a panning demonstration.
Well I thank you for this valuable information. I didn't need it to assist me in foraging for gold. I merely need to be able to tell my grand kids where gold comes from when they ask me. You made me an instant professor.
I have wondered about how gold was formed and related to volcanoes my whole life. I got it when you drew the first picture. You sir are a great teacher.
Thanks for the video. Most people don't realize how much work it is to get gold. In my much younger years I used to dredge for gold. Also, I was working toward a mining certificate at Antelope Valley College until they cancelled the program over budgeting before I finished. We went on several field trips, mostly to mines around Mojave, but also trips to the Stanislaus River, Randsburg, and Lockwood Valley. Rick Balough was the instructor for most geology and placer mining classes. Cecil Burton did the hard rock mining portions including fire assaying. His son had a mine near Mojave and another family member had the Tropico Mine in Rosamond. I learned a lot from those classes, and hopefully I contributed something from recounting my first hand experiences. Those were the good 'ol days 35 years ago.
Thank you. If you want something more detailed and up to date watch the videos I list in this recent video of mine. ua-cam.com/video/TQaiEnT0oes/v-deo.html
I agree with you completely!! To me it also shows that he's a damn good man! He's a geologist/humanitarian! I have a lot of respect & appreciation for people like this!
@@hardrockuniversity7283 thank you so much! What if the veins are very old petrified huge tree roots? Plants accumulate minerals from deep in the earth and bring them up in their roots etc. Maybe a lightning strike works with this like a type of electrolysis or something. I'm just thinking out of the box, wondering... Especially considering the edges of the vain coincide with where bark would be if it was a thicker root or fallen tree that was buried in mud after the flood. Love your videos and thank you so much!
Thank you so much sir for the lectures you are putting on UA-cam. I am a mining engineering student and I love watching your videos. I get a lot more deeper understanding from watching your videos because in class sometimes I get the terminology but you really explain it better.
Great lesson. I use to work at an underground hard rock gold mine in California many years ago. This video explained what I saw first hand right in front of me. I have learned a lot from your video and plan to watch more.
This is not where gold comes from. This is how gold reach's the surface. Gold is made in exploding stars as is all heavy metals. Diamonds are made in the earth and brought up by volcanos. Very informative as to how gold comes to the surface. Nice and informative. Thanks for posting.
Deep hydrothermal sources have temperature and pressure high enough to create supercritical water. This is capable of dissolving most all minerals. This happens at depths over 7300 feet and 705°F
Greetings Keith! I love your lessons, keep it goin! I'm a relatively new gold prospector currently learning the ropes. Right now all i have is a bucket, gold pan, a screen and a folding shovel, none of that fancy equipment ya got there. lol, one day I'll hopefully be able to expand. (Not gold much in Kansas) Your lessons have really encouraged me to keep going and grow my skills. One thing I like about your approach is that it is objective and logical! I had just recently this past week spent a few day in Colorado and did some gold panning along the wolf creek pass near South Fork. My biggest struggle was finding the right location to sample along the creek, but I was able to find some specks of gold within my first few tries. Later on I returned to the Cabin and I became really stoked when I watched lesson 24.Next time I go out there I'll use the tapping technique religiously! I could have probably identified lots more gold using it. For now I'll practice with what I got here in my garage. I did bring some samples with me to help with practice. Anyhow, great videos I'll be going through them thoroughly to help me get better. By the time I get back out there, I'll have some good knowledge! Thanks a whole bunch!!!
sorry to tell you you are listening to a lier 1000 percent he dont know wear gold comes from i do....and it amazing when you find out the truth..you are living this mans lies..and you will proberly teach your children his lies..i asked him wear he learned this info from lets see what he says...ill will prove he wrong...and when u find out he is wrong what will you say and think
Came back to this video after concluding my lessons on volcanoes. Where do you think you would be able find gold around recent erupted volcanoes such as Kilauea vs. more explosive volcanoes such as Krakatoa in 1883? Which volcano would have more you think?
Come back to those islands after several million years.. then you'll find your gold. Still needs time for precipitation, and then erosion of the rock - unless you're mining a seam.
that was fun. had a eureka moment when you started drawing the water precipitation. I bet that's also why gemstones look so cool when you cut them open with the many different layers in different colors and such. great video!
HOLY MOLY! I have been visualizing how gold gets to the rivers but never could grasp the concept. But seeing you draw the lava pit and ground water leaching in and under immense heat and pressure sprays through cracks and builds up mineral deposits sort of like a rusty pipe. Thank you my friend! I’m surrounded by volcanos in the PNW time to go looking!
There is gold along the entire west coast. It is spotty though. A local prospectors club can quickly get you lined out on how to find gold in YOUR area.
Your kinda like a trash digger if you think about it. Like searching through a bunch of crap people left behind for enough money to go get drunk and high
Hi, fantastic video I really found it helpful in understanding the formation of quartz veins. One quick question, you mention that that the water dissolves the minerals, does this include gold and, if so, how is this so considering gold is not water-soluble?
At high temperatures and with certain ions in the solution, gold IS soluble. We are talking 300 degrees C here and high pressure. Gold is insoluble under normal conditions, rock is also a solid under normal conditions.
Thank you. My 'extensive knowledge' is more broad than deep I guess. I know a fair amount about a lot of things, which is good to start with. There are a lot of people who know a lot wore about individual specialties. However, that also tends to give them tunnel vision at times. You know the old saying, 'To a man with a hammer, all problems look like a nail'. I like a more complete tool bax. Thank you for your service. Keith
Well, perhaps your "extensive knowledge" might be better described as "practical knowledge" and I'll take the word of someone who has learned by doing before the word of a bookworm. Your explanation makes sense to me and that is practical education. Thanks again. And thank you for your patriotism. All three of my sons also served in the Marine Corps with 4 combat tours in Iraq total between them. It is good to know that great Americans still appreciate the sacrifice.
Hello Marine, ( A title of honor as you and I both know) I have been told I have the 'teaching gene' by a friend. I think what that mainly means is that I can put myself in someone else's shoes and also remember what got me confused. I am glad I am presenting the info well, as that is what HRU is all about. I hate people to waste their hard earned time and money when a little info could help so much. Your sons - Semper Fi cubed! You and yours have sacrificed so much for me and my children and grand children. So many people fail to realize the strain EVERONE is put through during a combat deployment. Thank them all (and yourself) for me. At least now we have the internet. But I wonder... Is it better to see one's family when you can't go to them, or is it better to focus on the job at hand? I suppose, like most things, it depends on the person. I suspect you will be happy to know that my other half has been very busy on the internet the last few months making some significant contributions to the campaign of a certain military supporter we both know. It takes all kinds to keep liberty alive. We are not vets in this house, but we are patriots. She has been working like a demon for months to achieve what she feels is the best for this country, and I honor her too. Best wishes, Keith
I gather that you're down in Arizona and I'm up here in NW Wyoming. I spent the last couple of days doing some panning on a creek not too far from Yellowstone, but the gold around here is very fine and very sparse. I did bring home a little gold... and I do mean little, but the real treasure in found in just being out there enjoying the mountains while prospecting. I have been on a mission to learn all I can about gold, gems, and the geology related to them. It's a challenge since geology is a rather complex subject, but little by little, I'm learning. Videos like yours are so valuable to that process and I appreciate the effort you make to present them. To learn that you and your family are patriots and good people is icing on the cake. Folks like you are the reason that young people serve our country because together we make our nation great. I'm glad our certain military supporter is headed for Washington to drain the swamp so that greatness will be preserved. My 4th grand child is due this week so your wife's efforts are well appreciated and not underestimated one bit. Thank you for your kindness and taking the time to respond. I have already subbed you and will continue to frequent your channel. God Bless, Tom
I have a serious recommendation for you. There is a series of videos on UA-cam called 'Ore Deposits 101' that is very good. You will have to pause a fair amount while you look up definitions in another window, but they are easily understandable when you do so and you will learn A LOT! It is a bunch of valuable info in an interesting format. You will enjoy it. Yep, I'm in AZ. Love the fishing up there but southern Wyoming is incredibly boring to drive through- hours of sage brush and not a single tree! I prefer up by the Montana border. Used to have an uncle in Bozeman - great fly fisherman. Are you using my panning technique to test for the very fine gold? How is it working for you? Going to a local anti Trump demo tomorrow for intelligence gathering. Hope we get home on our feet. :-) I live very near down town and the house is already at FPCON Bravo as a precaution. May God Bless America (and may we deserve it) Keith
Hey well done. Great video, however you should also include or do a video going over intrusive deposits. I know that you where talking about AZ specifically but in other states such as CO we have intrusive as well as epithermal deposits.
Hi, I'm looking for the chemical equations associated with gold formation during retrograde metamorphism of pyroxenes to amphiboles. Do you think you can help me please! Many thanks.
I wish I could, but the question is way beyond my expertise. I am just an experienced miner rather than an academic. The name of the channel is just that- a name. This is not an educational institution. If you can't find the information you need though, I can probably put you in touch with people who can answer your questions.
Gold does not come from the earth. It comes from supernova explosions period! Great video on how gold is brought to the earths surface through volcanism.
When atoms or molecules come out of solution they form lattices and only certain atoms will fit in certain ways. The rule of thumb is 'like attracts like'. You could also look up 'differential crystallization' for more details.
Ancient Indian legends say when the giants fell, you saw them and all living matter with water in them turn to stone! Only those below the surface survived and those survivors watched as all things with water, oceans, trees, man, giants, all that water was ignited and they burned turning to stone. When they fell the natives noted where the giants fell and how! They noted where their legs lay, where the feet were, where the heart was and in the big arteries of the upper legs, the lower legs and feet, and the heart they found quartz, amethyst and gold! Indians say find the giant, see how it lay, follow these spots and dig and you will find gold!
There actually is giants, they were the fallen angels children that mated with humans. Example being the rome or greek 'gods' they were worshipped for having excess abilities and power of the spirit world. Giants are the children of them. Its very true. Thank you for posting that bro and dont mind the haters. They just dont want to learn it will burst their bubble they live in
Truth Seekers - that’s where the “how” came from. As the Indians would meet new tribes they would raise their hand and count the fingers. Beware of the 6 fingered creature.
noob here, but what i got out of this is how gold is distributed thoughout the earth. i was looking more for how it's created... like a star nova or something. does the earth have the mass/energy etc. to 'make' gold or was it simply deposited here as the earth formed? thanks!
Gold is synthesized in supernova explosions. The nebula that condensed to form the solar system had such gold in it and that was incorporated into the Earth as it accreted.
Gravity sucks, so believe it or not way down in the Earths core is a mass of molten Gold, that is large enough to cover the entire surface of the earth in a layer of Gold a yard or so high. All the other dense minerals are down there too. If you can remember gravity and density, youre well on the way.
It seems possible. The current theory is an iron core, but fractional stratification of liquids works on the surface and I don't think liquid gold dissolves in liquid iron.
Because I am a Christian I don't buy into all the nonsense spewed in this video. I go with Dr. Browns hydro-plate theory. Gold, uranium and such were created by Z-pinch caused by piezoelectric currents in the earth. If as these "scientists" claim that the earth started as a molten mass all heavy elements would be in the center of the earth so how did they get to the surface? I read here one person claims super nova, which is nonsense as there are only a small number of observable supernova remnants visible in the milky way galaxy. Mainstream geological history is total garbage if you take a serious look at it.
I like to call gold --> dinosaur snot because of its age. The water flow and cracks being filled with mineralization is understood. I enjoyed your presentation and saved it for later viewing again. Can you elaborate on sampling, and do you take an assay the samples? Thank you.
Here is a video on sampling hard rock veins: ua-cam.com/video/m-OI5sXANqU/v-deo.html Here is a video on Sample preparation: ua-cam.com/video/fzL5JI80AHw/v-deo.html And here is a video on hand panning micro-fine gold: ua-cam.com/video/IPEUJQi7-Lc/v-deo.html I will usually hand pan a sample and then send it off for fire assay if indicated. In my case I am not terribly interested in low grade ore generally, so even with very fine gold I can get some in the pan. The current project I am working on has gold where 80% of it by weight is a quarter the size of talcum powder. Much smaller than in the demonstration. However, even with that I can get enough to see. Keith
@@natekeyser9388 The atoms are originally created primarily in Neutron Star Merger events rather than Core Collapse Supernovas according to the latest theories which are WAYYYYYY over my head, but the smart guys seem to agree.
@@hardrockuniversity7283 I believe it is an important, yet little understood profundity, that these "precious metals" gold, silver, platinum, and palladium are all truly EXTRATERRESTRIAL materials and thus are NOT renewable in the inner workings of Earth. I have not met many people that truly comprehend the gravity of this fact. Admittedly we really have no idea of just how much of these precious metals are present on and inside our Earth, but one can assume its likely always going to be a pain to get to it, making it one of if not the best forms of currency.
@@natekeyser9388 I agree with the currency angle. You might investigate the amount of physical gold and silver compared to the amount being carried on paper accounts. Might get interesting...
Excellent Explanation. Thank you! What would interest me is how the metals come to be intonthe Magma. After all most of the heavy metals should sink down into the earth. What does it do in some bubble if Magma in the crust. I guess most volcanoes that generate ore deposits are volcanos above subduction zones. Coukd it be that the metals being deposited in the veins is melted oceanic crust with the manganese nodules having been melted along the ocean floor and being stopped from sinking rapidly in the mantle is the subducted oceanic crust. So is the metal deposits are the concentrated minerals from manganese nodules. If yes, where is the manganese, why do we only see precious or semiprescioud metals in the veins. Are the other metals bound harder into the magma matrix, or less steam aoluble?
@@hardrockuniversity7283 The closest theory I know on the idea of gold coming from stars as radiation, is that when a star goes nova, the blast squeezes lighter elements into heavier ones and they must then rain upon the earth as it is forming, then work their way back up to the surface through veins as in your video. However, spectral analysis of our sun shows that heavier elements are created in the sun's atmosphere or corona and travel mainly inwards towards the core of the sun. Evidence from the SAFIRE project shows the same process, that elements that were not there are created in channels of movement from the coronal area towards the core. A form of Marklund convection from the corona towards the core, upon electrical discharge to the core. Evidence from our sun through spectral analysis...….. ua-cam.com/video/5GqQWExwrtE/v-deo.html Lab verified experiments of created elements in SAFIRE...…….. ua-cam.com/video/L69ttX3kviw/v-deo.html Edo's structured atomic model...…….. etherealmatters.org/book/future/atomizer-module
" the theory is when we start pulling Gold from the spectrum We better have our understanding of how integrated we our with the natural process of electricity or we could never respect the knowledge enough to utilize to elevate the whole of the Human race, all life connected. "
@@westrnite I think the next form of energy production is going to come from hydrogen, but not fusion reactors, but, fission reactors. Resonating or vibrating the proton to release its stored energy. Energy stored there at the galactic core, by lining up the dielectric, or ether medium into matter as per Halton Arp, shooting out of the galactic jets as neutrons. Energy released the way the sun does, or SAFIRE or the SKUNK works. Gold or other heavier elements require some energy to get them to go together as per Tesla, whirled or spiraled together at near the speed of light, in what we now know as Marklund convection, the input energy to create gold may never be practical.
and that was the only correct answer!, this is why you find gold all over the world!. the magma and lava is just a mode of transport like the meteorites!.
Dear Keith, Enjoyed the videos very much.. I learn a lot from each video lesson you have put up. I take notes thinking there will be a pop quiz most anytime. You certainly have the talent and knowledge to teach us beginners. Please do not go out alone to the field...... always have a companion.My best to you and Good Luck on your adventures. Ron.
Thank you for the kind words. I usually have a companion or two. There are some situations close to home where I feel comfortable enough to do a few things alone, but I always have someone I can trust monitoring my situation as best they can who will send help if I don't check in on time. Last trip I had a companion and still called in four times at points with cell coverage. If you have any questions please ask. Keith
Thanks for the sharing all the tips. I would like to hear about the geology..the source and migration of the placer deposits...and I really liked learning all about the equipment.. the AVR(?) Active vibration reduction hammer or drill.no one else has taken the time to explain it's use as well as you did, what was the generator size? Keep up the good work explaining/ informing . the complete package. Do you have videos on mining oo identifying minerals or gems Also enjoyed the evaluation video..Since I am a PEng.. that was an interesting segment. If you have others that would be great. Where do you live? All the best, Ron
I always size my generator to run at no more than 65% capacity standard load and 80% peak load. For this I use a 3000w Champion generator that costs $300-350 and lasts OK. It's not as good as a Honda, but I can buy four for the price of one Honda. Just change the oil every week and they last about a year at 50 hrs/wk. There is a very good video series on youtube called 'Ore Deposits 101' That is like a college level course on ore body formation. Every type of metallic ore body is covered. Can't recommend it enough. I live in Tucson, AZ. We are currently looking for a profitable small ore body so that we can video the whole process from initial site survey to profitability. Working in the back yard today processing ore samples. Letting the gold dry now to weigh it to see what the recovery was. You should also check out my web site as there are some useful tools there and I will be adding more as time goes on. Thank you for the kind words, Keith
@@hardrockuniversity7283 Earth 10,000 yrs old, great flood 6,000yrs ago. Population data tables support this FACT! Evil-lou-shun was created to push the Darwin/No GOD agenda.
@Just Looking Not everything (elements) is from a supernova. Some things, like gold for instance, came from neutron star collisions which form matter from a different process than do supernovas. But, if you really want to get down to it, previous to star formation, matter was created by dynamics that resulted in the formation of our universe, a process that created all the matter/energy we know of. Supernovas merely fused that original matter into heavier elements.
We are fortunate to have you Keith. Are the old magma chambers what become mining stoops? Is it possible to find these filled chambers with cave detecting ground scanning equipment? I have exposed outcroppings on my claim with vertical earthquake fractures, if I measure the degree angles, is the point where they cross underground the best place to mine down to? Any opinions on Dorr and Kokoweef?
It is not the magma itself that deposits the gold, but the very hot mineralized water associated with the volcanic activity. Here is a video I uploaded a short time ago with the addresses of two videos with the latest information on how many gold ore bodies are formed: ua-cam.com/video/TQaiEnT0oes/v-deo.html This is new professional level information in an easy to understand format There are some minerals, notably platinum and chromium, that do form directly from magma in what are known as 'sill deposits'. Essentially, these are very high melting point minerals that crystallize first and then settle down to the bottom of the magma chamber and settle on the floor just like the dust on a window sill- thus, the name. There are so many complicating factors that I cannot make any kind of judgement on the idea of following the line of fracture to some kind of origin point. The most important aspect to me is: Is there any sign of valuable mineralization in the observable fractures? Bed rock can be fractured by many processes and only a few of them can deposit valuable minerals. WRT the Kokoweef Mine, I had never heard of it until you brought it to my attention.
Well, let's consider the facts. Tens of millions suggests anything from ten to ninety million years. Given the rate of the subduction zone under the western USA and Mexico, the descending plate melts as the crust moves over the hot spots. This creates strings of volcanoes, over billions of years (See Devil's Tower National Monument). The result is the rocky layers melt and float upward, forming magma chambers. Ancient volcanoes, most now eroded, left these deposits behind as the subduction process moved westward (American crust over the Pacific plates). Currently, the hot spots are directly east of the present coastline. Most of the gold in the Sierras (think Sutter's Mill goldrush of 1849) were created exactly this way. So, the volcanoes under Arizona are extinct, but the ones in California, Oregon and Washington state are still active. So, the easternmost volcanoes could be 100's of millions old, while the vulcanism seen on the American section of the Pacific "ring of fire" is happening now. Geology stops for no human activity (see Pompeii).
Actually the topography here is mainly Basin and Range Province and the volcanism is less than 50 million years old en.wikipedia.org/wiki/Basin_and_Range_Province
@@hardrockuniversity7283 disappointed that you'd cite Wiki, which is not suitable or citable for any sort of academic reference. Thanks for the informative video tho. Nice work!
Sensational... you explained in 10 minutes what ive been trying to understand since i bought my metal detector 2 years ago. Good work Thanks heaps Paul
I live your no nonsence factual method of describing things. I have some common opal which supposedly came from an abandoned mine near a gyser. The material is so beautiful and knappable I'm trying to learn more about it, how it is formed and what other treasures are found with it. Have you presented anything on this type mining. Thanks your channel is awesome.
No I have not. Opal is very beautiful, but it is not in my field. I would be happy to mine it if it was a good mine though. My wife would definitely approve. :-)
Gold is thought to have been produced in supernova nucleosynthesis, and from the collision of neutron stars, and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core.
Actually, the current best astrophysical theories postulate that the vast majority of gold atoms were created in neutron star mergers well after the Big Bang
Ultimately , the element gold , AU, is created in the cores of large stars during a supernova explosion where the temperature and pressure is great enough to fuse other elements together to create AU , or gold. This and other elements are then distributed to gas clouds that are near the explosion. When the gas cloud contracts to form a star and planets, like our solar system, these elements then get incorporated into the star and planets that form.
None of those criteria have much to do with whether or not there is gold mineralization. However, high grade specimen gold ore is almost always found in smaller veins where the slow moving solution can slowly build up larger particles of gold.
I am not a geologist; but i was expecting something different from this video. The title "Where Does Gold Come From?" would seem to indicate a lesson on the formation of gold. Instead, we got a lesson on how it propagates upward to be found on the surface. "Where To Look For Gold" would be a more apt title.
@@hardrockuniversity7283 Thank you for the information. I just subscribed and thumb up. Thanks again, your are very generous to give away your information like this on UA-cam. I have not taken it for granted and I am listening very carefully. So again, thank you for the information.

It is also very good at signaling for help if needed. I have never had to draw it for self defense. I HAVE run into groups of migrants and some lone smugglers. By not looking helpless, it keeps anyone from getting ideas.
Yep. And a lot of research has been done about how it all went down. You should be able to get a lot of info off the internet about your local situation.
Great info thanks. This is how gold ends up in quartz veins and other hard rocks, but where does gold actually come from before it is shot up with the magma? Is there just a whole bunch of liquid gold sitting down under the magma or what?
In the crust it is widely distributed in the rock and the geothermal solution dissolves it. In magma, it may be in the melt and then concentrated by water dissolved in the magma and then deposited as these 'magmatic waters' flow away from the last remnants of a cooling magma chamber if it doesn't erupt. Some people thing thee might be a lot of gold in the Earth's core concentrated like the gold in a fire assay at the time the earth was all molten.
@@hardrockuniversity7283 If the Earth does have a golden core I imagine there would be quite the battle over mineral rights should we ever make it there! Thanks again for sharing your wealth of information and happy hunting!
At one time or another. However, most of that knowledge gets lost over time. Plus, new extraction techniques change the financial equation from time to time. Almost all of the big open pit/heap leach operations come from deposits that were found years ago, but not possible to exploit profitably until heavy equipment and heap leaching became available.
Not in hard rock. It gets more complicated. The project I am working on now, the gold is smaller than powdered sugar by quite a bit. I have to use entirely different methods.
In 10 minutes, we still are no smarter in knowing where gold comes from! Yes, it's in the vein but HOW did it get there? Back to the original question, "Where Does Gold Come From?"
Cool video. I would have probably started with its astrophysical origins of being forged in the death throes of a star going supernova and of it then being blasted throughout the interstellar medium to eventually being incorporated into a rocky planet!
Very informative, but I would like toknow if the water , underpressure in the magma, is hot enough to melt the minerals such as gold? Also if one goes deeper towards the center of the earth are there layers of molten minerals or is there a mixture like a fruit cake ?
An excellent, informative video. Were the Klondike gold fields formed from illuvial and subsequent alluvial deposits -from weathered gold bearing quartz veins?

Thanks for the video. Most people don't realize how much work it is to get gold.
In my much younger years I used to dredge for gold. Also, I was working toward a mining certificate at Antelope Valley College until they cancelled the program over budgeting before I finished. We went on several field trips, mostly to mines around Mojave, but also trips to the Stanislaus River, Randsburg, and Lockwood Valley. Rick Balough was the instructor for most geology and placer mining classes. Cecil Burton did the hard rock mining portions including fire assaying. His son had a mine near Mojave and another family member had the Tropico Mine in Rosamond. I learned a lot from those classes, and hopefully I contributed something from recounting my first hand experiences. Those were the good 'ol days 35 years ago.
Thank you.
I got my start at the Chemgold (now Glamis Gold) in Imperial County CA. Then I moved to Goldfields Mesquite for another five years.
Great explanation thank you. Other geologists use too many technical words and jargon you kept it basic and well illustrated. Cheers

@@hardrockuniversity7283 thank you so much! What if the veins are very old petrified huge tree roots? Plants accumulate minerals from deep in the earth and bring them up in their roots etc. Maybe a lightning strike works with this like a type of electrolysis or something. I'm just thinking out of the box, wondering... Especially considering the edges of the vain coincide with where bark would be if it was a thicker root or fallen tree that was buried in mud after the flood.

Excellent lesson Professor 👍🏻 Thank you for all your hard earned an learned lessons you share an teach!
Thank you. I do not have any degrees, but I do have a fair amount of experience.

Greetings Keith! I love your lessons, keep it goin! I'm a relatively new gold prospector currently learning the ropes. Right now all i have is a bucket, gold pan, a screen and a folding shovel, none of that fancy equipment ya got there. lol, one day I'll hopefully be able to expand. (Not gold much in Kansas) Your lessons have really encouraged me to keep going and grow my skills. One thing I like about your approach is that it is objective and logical!
I had just recently this past week spent a few day in Colorado and did some gold panning along the wolf creek pass near South Fork. My biggest struggle was finding the right location to sample along the creek, but I was able to find some specks of gold within my first few tries. Later on I returned to the Cabin and
I became really stoked when I watched lesson 24.Next time I go out there I'll use the tapping technique religiously! I could have probably identified lots more gold using it. For now I'll practice with what I got here in my garage. I did bring some samples with me to help with practice. Anyhow, great videos I'll be going through them thoroughly to help me get better. By the time I get back out there, I'll have some good knowledge! Thanks a whole bunch!!!

Came back to this video after concluding my lessons on volcanoes. Where do you think you would be able find gold around recent erupted volcanoes such as Kilauea vs. more explosive volcanoes such as Krakatoa in 1883? Which volcano would have more you think?

HOLY MOLY! I have been visualizing how gold gets to the rivers but never could grasp the concept. But seeing you draw the lava pit and ground water leaching in and under immense heat and pressure sprays through cracks and builds up mineral deposits sort of like a rusty pipe. Thank you my friend!

Hi, fantastic video I really found it helpful in understanding the formation of quartz veins. One quick question, you mention that that the water dissolves the minerals, does this include gold and, if so, how is this so considering gold is not water-soluble?
At high temperatures and with certain ions in the solution, gold IS soluble. We are talking 300 degrees C here and high pressure. Gold is insoluble under normal conditions, rock is also a solid under normal conditions.
I use to strip gold off of computer parts. Hydrogen Cyanide dissolves gold.
Love my gold...

My 'extensive knowledge' is more broad than deep I guess. I know a fair amount about a lot of things, which is good to start with. There are a lot of people who know a lot wore about individual specialties. However, that also tends to give them tunnel vision at times.
You know the old saying, 'To a man with a hammer, all problems look like a nail'. I like a more complete tool bax.

Well, perhaps your "extensive knowledge" might be better described as "practical knowledge" and I'll take the word of someone who has learned by doing before the word of a bookworm. Your explanation makes sense to me and that is practical education. Thanks again.

Hello Marine,

I have been told I have the 'teaching gene' by a friend. I think what that mainly means is that I can put myself in someone else's shoes and also remember what got me confused. I am glad I am presenting the info well, as that is what HRU is all about. I hate people to waste their hard earned time and money when a little info could help so much.

You and yours have sacrificed so much for me and my children and grand children. So many people fail to realize the strain EVERONE is put through during a combat deployment. Thank them all (and yourself) for me.
At least now we have the internet. But I wonder... Is it better to see one's family when you can't go to them, or is it better to focus on the job at hand? I suppose, like most things, it depends on the person.
I suspect you will be happy to know that my other half has been very busy on the internet the last few months making some significant contributions to the campaign of a certain military supporter we both know. It takes all kinds to keep liberty alive. We are not vets in this house, but we are patriots. She has been working like a demon for months to achieve what she feels is the best for this country, and I honor her too.

I gather that you're down in Arizona and I'm up here in NW Wyoming. I spent the last couple of days doing some panning on a creek not too far from Yellowstone, but the gold around here is very fine and very sparse. I did bring home a little gold... and I do mean little, but the real treasure in found in just being out there enjoying the mountains while prospecting. I have been on a mission to learn all I can about gold, gems, and the geology related to them. It's a challenge since geology is a rather complex subject, but little by little, I'm learning. Videos like yours are so valuable to that process and I appreciate the effort you make to present them.
To learn that you and your family are patriots and good people is icing on the cake. Folks like you are the reason that young people serve our country because together we make our nation great. I'm glad our certain military supporter is headed for Washington to drain the swamp so that greatness will be preserved.

@@matthewadams9900 that doesn't make any sense whatsoever
Why isnt the gold just mixed atomically with the other minerals ? Why does it clump togeter in gold veins ?
When atoms or molecules come out of solution they form lattices and only certain atoms will fit in certain ways. The rule of thumb is 'like attracts like'. You could also look up 'differential crystallization' for more details.

Ancient Indian legends say when the giants fell, you saw them and all living matter with water in them turn to stone! Only those below the surface survived and those survivors watched as all things with water, oceans, trees, man, giants, all that water was ignited and they burned turning to stone. When they fell the natives noted where the giants fell and how! They noted where their legs lay, where the feet were, where the heart was and in the big arteries of the upper legs, the lower legs and feet, and the heart they found quartz, amethyst and gold! Indians say find the giant, see how it lay, follow these spots and dig and you will find gold!
There actually is giants, they were the fallen angels children that mated with humans. Example being the rome or greek 'gods' they were worshipped for having excess abilities and power of the spirit world. Giants are the children of them. Its very true.

I watched alot of garbage how is gold made videos...but i definitely think i can trust this video
Thank you
noob here, but what i got out of this is how gold is distributed thoughout the earth. i was looking more for how it's created... like a star nova or something. does the earth have the mass/energy etc. to 'make' gold or was it simply deposited here as the earth formed?
thanks!
Gold is synthesized in supernova explosions. The nebula that condensed to form the solar system had such gold in it and that was incorporated into the Earth as it accreted.
Gravity sucks, so believe it or not way down in the Earths core is a mass of molten Gold, that is large enough to cover the entire surface of the earth in a layer of Gold a yard or so high. All the other dense minerals are down there too. If you can remember gravity and density, youre well on the way.
It seems possible. The current theory is an iron core, but fractional stratification of liquids works on the surface and I don't think liquid gold dissolves in liquid iron.
Have a crack at this www.abc.net.au/science/articles/2013/12/03/3903924.htm
Because I am a Christian I don't buy into all the nonsense spewed in this video. I go with Dr. Browns hydro-plate theory. Gold, uranium and such were created by Z-pinch caused by piezoelectric currents in the earth. If as these "scientists" claim that the earth started as a molten mass all heavy elements would be in the center of the earth so how did they get to the surface? I read here one person claims super nova, which is nonsense as there are only a small number of observable supernova remnants visible in the milky way galaxy. Mainstream geological history is total garbage if you take a serious look at it.
I like to call gold --> dinosaur snot because of its age. The water flow and cracks being filled with mineralization is understood. I enjoyed your presentation and saved it for later viewing again. Can you elaborate on sampling, and do you take an assay the samples? Thank you.
Here is a video on sampling hard rock veins:
ua-cam.com/video/m-OI5sXANqU/v-deo.html
Here is a video on Sample preparation:
ua-cam.com/video/fzL5JI80AHw/v-deo.html
And here is a video on hand panning micro-fine gold:
ua-cam.com/video/IPEUJQi7-Lc/v-deo.html
I will usually hand pan a sample and then send it off for fire assay if indicated. In my case I am not terribly interested in low grade ore generally, so even with very fine gold I can get some in the pan. The current project I am working on has gold where 80% of it by weight is a quarter the size of talcum powder. Much smaller than in the demonstration. However, even with that I can get enough to see.

wrong
Excellent Explanation. Thank you!
What would interest me is how the metals come to be intonthe Magma. After all most of the heavy metals should sink down into the earth. What does it do in some bubble if Magma in the crust.
I guess most volcanoes that generate ore deposits are volcanos above subduction zones. Coukd it be that the metals being deposited in the veins is melted oceanic crust with the manganese nodules having been melted along the ocean floor and being stopped from sinking rapidly in the mantle is the subducted oceanic crust.
So is the metal deposits are the concentrated minerals from manganese nodules. If yes, where is the manganese, why do we only see precious or semiprescioud metals in the veins. Are the other metals bound harder into the magma matrix, or less steam aoluble?
'' GOLD IS EVERYWHERE'' END OF STORY.

I am thinking of maybe updating this video a little, but then I would lose all the views.
"Gold comes from the sun and stars as radiation." He's talking about spent decay precipitation. "
Google can't seem to find a reference for this phenomenon. Can you briefly explain the theory?
Keith
@@hardrockuniversity7283 The closest theory I know on the idea of gold coming from stars as radiation, is that when a star goes nova, the blast squeezes lighter elements into heavier ones and they must then rain upon the earth as it is forming, then work their way back up to the surface through veins as in your video.
However, spectral analysis of our sun shows that heavier elements are created in the sun's atmosphere or corona and travel mainly inwards towards the core of the sun. Evidence from the SAFIRE project shows the same process, that elements that were not there are created in channels of movement from the coronal area towards the core. A form of Marklund convection from the corona towards the core, upon electrical discharge to the core.

" the theory is when we start pulling Gold from the spectrum We better have our understanding of how integrated we our with the natural process of electricity or we could never respect the knowledge enough to utilize to elevate the whole of the Human race, all life connected. "
@@westrnite I think the next form of energy production is going to come from hydrogen, but not fusion reactors, but, fission reactors. Resonating or vibrating the proton to release its stored energy. Energy stored there at the galactic core, by lining up the dielectric, or ether medium into matter as per Halton Arp, shooting out of the galactic jets as neutrons.
Energy released the way the sun does, or SAFIRE or the SKUNK works.
Gold or other heavier elements require some energy to get them to go together as per Tesla, whirled or spiraled together at near the speed of light, in what we now know as Marklund convection, the input energy to create gold may never be practical.

I always size my generator to run at no more than 65% capacity standard load and 80% peak load. For this I use a 3000w Champion generator that costs $300-350 and lasts OK. It's not as good as a Honda, but I can buy four for the price of one Honda. Just change the oil every week and they last about a year at 50 hrs/wk.
There is a very good video series on youtube called 'Ore Deposits 101'

Atomicwedgie81 your moniker suggests you want to be click bait.
@Just Looking Not everything (elements) is from a supernova. Some things, like gold for instance, came from neutron star collisions which form matter from a different process than do supernovas. But, if you really want to get down to it, previous to star formation, matter was created by dynamics that resulted in the formation of our universe, a process that created all the matter/energy we know of. Supernovas merely fused that original matter into heavier elements.
We are fortunate to have you Keith. Are the old magma chambers what become mining stoops? Is it possible to find these filled chambers with cave detecting ground scanning equipment? I have exposed outcroppings on my claim with vertical earthquake fractures, if I measure the degree angles, is the point where they cross underground the best place to mine down to? Any opinions on Dorr and Kokoweef?
It is not the magma itself that deposits the gold, but the very hot mineralized water associated with the volcanic activity. Here is a video I uploaded a short time ago with the addresses of two videos with the latest information on how many gold ore bodies are formed: ua-cam.com/video/TQaiEnT0oes/v-deo.html
This is new professional level information in an easy to understand format
There are some minerals, notably platinum and chromium, that do form directly from magma in what are known as 'sill deposits'. Essentially, these are very high melting point minerals that crystallize first and then settle down to the bottom of the magma chamber and settle on the floor just like the dust on a window sill- thus, the name.
There are so many complicating factors that I cannot make any kind of judgement on the idea of following the line of fracture to some kind of origin point. The most important aspect to me is: Is there any sign of valuable mineralization in the observable fractures? Bed rock can be fractured by many processes and only a few of them can deposit valuable minerals.
WRT the Kokoweef Mine, I had never heard of it until you brought it to my attention.
"10's of millions of years ago"....... WRONG. Nice try though.
? Are we talking theology here or something else?
Well, let's consider the facts. Tens of millions suggests anything from ten to ninety million years. Given the rate of the subduction zone under the western USA and Mexico, the descending plate melts as the crust moves over the hot spots. This creates strings of volcanoes, over billions of years (See Devil's Tower National Monument).
The result is the rocky layers melt and float upward, forming magma chambers. Ancient volcanoes, most now eroded, left these deposits behind as the subduction process moved westward (American crust over the Pacific plates). Currently, the hot spots are directly east of the present coastline.
Most of the gold in the Sierras (think Sutter's Mill goldrush of 1849) were created exactly this way. So, the volcanoes under Arizona are extinct, but the ones in California, Oregon and Washington state are still active. So, the easternmost volcanoes could be 100's of millions old, while the vulcanism seen on the American section of the Pacific "ring of fire" is happening now.
Geology stops for no human activity (see Pompeii).
Actually the topography here is mainly Basin and Range Province and the volcanism is less than 50 million years old en.wikipedia.org/wiki/Basin_and_Range_Province
@@hardrockuniversity7283 disappointed that you'd cite Wiki, which is not suitable or citable for any sort of academic reference. Thanks for the informative video tho. Nice work!
@@matthewronsson While it is not highly reliable, it is highly accessible. :-)
Thank you.
I took the mine tour in Cripple Creek, CO, best thing I ever did.
Yep. Luckily I have had several 'tours' that were a bit more comprehensive.
Sensational... you explained in 10 minutes what ive been trying to understand since i bought my metal detector 2 years ago. Good work
Thanks heaps
Paul
Thank you.
The two videos- part 1& 2 on gold bearing fluids are not available.
I live your no nonsence factual method of describing things. I have some common opal which supposedly came from an abandoned mine near a gyser. The material is so beautiful and knappable I'm trying to learn more about it, how it is formed and what other treasures are found with it. Have you presented anything on this type mining.
Thanks your channel is awesome.
No I have not. Opal is very beautiful, but it is not in my field. I would be happy to mine it if it was a good mine though. My wife would definitely approve. :-)
Gold is thought to have been produced in supernova nucleosynthesis, and from the collision of neutron stars, and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core.
I agree on all counts.
Gold was created in the big bang along with all the other elements in the universe.
Actually, the current best astrophysical theories postulate that the vast majority of gold atoms were created in neutron star mergers well after the Big Bang
Ultimately , the element gold , AU, is created in the cores of large stars during a supernova explosion where the temperature and pressure is great enough to fuse other elements together to create AU , or gold.
This and other elements are then distributed to gas clouds that are near the explosion. When the gas cloud contracts to form a star and planets, like our solar system, these elements then get incorporated into the star and planets that form.
Yes, but much more from neutron star mergers than core collapse supernovae.
Thank u .
I wanna ask about which vains has much gold in it the thick ones or the thin ones?
The uniformed veins or the Un uniformed ones?
None of those criteria have much to do with whether or not there is gold mineralization. However, high grade specimen gold ore is almost always found in smaller veins where the slow moving solution can slowly build up larger particles of gold.
Awesome video that shows what I should be looking for
There is a steep learning curve at the beginning.
I am not a geologist; but i was expecting something different from this video. The title "Where Does Gold Come From?" would seem to indicate a lesson on the formation of gold. Instead, we got a lesson on how it propagates upward to be found on the surface. "Where To Look For Gold" would be a more apt title.
Possible, although that was the next video.
This is the best explanation ever !!!
Thank you
@@hardrockuniversity7283 Thank you for the information. I just subscribed and thumb up. Thanks again, your are very generous to give away your information like this on UA-cam. I have not taken it for granted and I am listening very carefully. So again, thank you for the information.
@@plutus205 You are most welcome. If you have any questions, you can always ask.
Chose this to find out where the element came from. This was interesting as well.
Thank you. The element is created in neutron star mergers.
Excellent, concise and clear.
Thank you
Very Interesting! Just one question, while I am not against it at all, why pack a gun? Thanks.
The area in the video is less than 10 miles from the US/ Mexico border and drug and people smuggling is a big thing. The .44 gives me an effective range of over 200 yards if needed. It is also very good at signaling for help if needed. I have never had to draw it for self defense. I HAVE run into groups of migrants and some lone smugglers. By not looking helpless, it keeps anyone from getting ideas.
Interesting, In my states of Victoria has massive gold deposits, and quartz veins are common in various rock types.
Yep. And a lot of research has been done about how it all went down. You should be able to get a lot of info off the internet about your local situation.
Wow, great vid. Informative and succinct.. Thank you.
You are most welcome.
Great info thanks. This is how gold ends up in quartz veins and other hard rocks, but where does gold actually come from before it is shot up with the magma? Is there just a whole bunch of liquid gold sitting down under the magma or what?
In the crust it is widely distributed in the rock and the geothermal solution dissolves it. In magma, it may be in the melt and then concentrated by water dissolved in the magma and then deposited as these 'magmatic waters' flow away from the last remnants of a cooling magma chamber if it doesn't erupt. Some people thing thee might be a lot of gold in the Earth's core concentrated like the gold in a fire assay at the time the earth was all molten.
@@hardrockuniversity7283 If the Earth does have a golden core I imagine there would be quite the battle over mineral rights should we ever make it there! Thanks again for sharing your wealth of information and happy hunting!
@@wildernesspost8764 You're most welcome.
Here's another one. In a state as big as Arizona, have miners looked at most every acre of ground?
At one time or another. However, most of that knowledge gets lost over time. Plus, new extraction techniques change the financial equation from time to time. Almost all of the big open pit/heap leach operations come from deposits that were found years ago, but not possible to exploit profitably until heavy equipment and heap leaching became available.
Well as a “Gold Rush” aficionado, I’ve watched every season…Gold is in the dirt ..and you have to move and wash the dirt..and there is the gold
Not in hard rock. It gets more complicated. The project I am working on now, the gold is smaller than powdered sugar by quite a bit. I have to use entirely different methods.
Such an empirical explainer
Thanks! This video confirms some ideas I’d been contemplating
You're welcome
In 10 minutes, we still are no smarter in knowing where gold comes from! Yes, it's in the vein but HOW did it get there? Back to the original question, "Where Does Gold Come From?"
Check the comments? That is the most common question and I have answered it for years. Neutron star mergers billions of years ago. 🙂
Cool video. I would have probably started with its astrophysical origins of being forged in the death throes of a star going supernova and of it then being blasted throughout the interstellar medium to eventually being incorporated into a rocky planet!
Apparently, you are correct. Read the comments ... :-)
Very informative, but I would like toknow if the water , underpressure in the magma, is hot enough to melt the minerals such as gold? Also if one goes deeper towards the center of the earth are there layers of molten minerals or is there a mixture like a fruit cake ?
In the case of gold, it is DISSOLVED in the hot water, not molten.
As you go deeper, the rocks get molten. Then can separate that way in some cases.
An excellent, informative video. Were the Klondike gold fields formed from illuvial and subsequent alluvial deposits -from weathered gold bearing quartz veins?
Those sandy deposits contain gold
