Pyrite: a great indicator of gold that may itself contain gold - It makes valuable mineral specimens

- Most prospectors learn early about pyrite or fool’s gold. But is pyrite always bad news for the prospector? No! the truth is that it can be an excellent indicator mineral for gold and in some cases, it does contain small amounts of gold. Pyrite is distinguished from gold by brittleness - a piece of gold hit with a hammer will flatten out while a piece of pyrite hit with a hammer will shatter into little bits. Normally pyrite only tricks prospectors when it is fresh and unweathered as it quickly rusts on exposure to rain and air, turning brown in color. Pyrite can be both a valuable ore mineral or a gangue (waste) mineral depending on the particular mineral occurrence. Where pyrite has significant gold, it is saved and processed for extraction. Where it is barren, it is treated as waste. In many mines, part of the gold is free milling, and part is bound up inside the pyrite crystal. The gold contained in the pyrite is not easily separated out, but the normal process is to recover the gold by fine crushing and leaching the ore using cyanide. The gold found within the pyrite occurs as tiny inclusions of metallic gold within the pyrite. There are a huge number of different gold ore types which are closely associated with pyrite, so it can be an excellent indicator mineral.
For those who want to learn more about prospecting and finding gold check out my book, Fists full of Gold. It’s an encyclopedia of everything on the topic of prospecting. It’s available on Amazon. You can find it at (affiliate):

It would be funny if Pyrite one day becomes the most valuable mineral due to it being used in the manufacturing of some future technology.
Its possible!
Very informative video Chris! Thanks for taking me along on your educational series! You’re a good teacher Chris and a nice guy too! Dan Brent
Thanks for the kind words.
What an incredibly informative video. Thank you for taking the time to put this together. I have leaned more from your videos than any other prospecting channel this far. Many thanks!!
Glad it was helpful!
An often overlooked subject in gold geology. Thanx Chris
Glad it was helpful.
Really a blessing to under your feet listening to your teachings. Thanks.
You are very welcome
Ah, yes, pyrite…nature’s way of saying “Gotcha!”
In many cases pyrite can be a good indicator.
It's iron and thats almost always a good indicator. I've heard said if any gold is present in the hydrothermal fluids (etc) the pyrite will crystalize out early, the higher gold content the smaller and more numerous the crytals. Large crystals generaly are fewer in number and indicate less/no gold....but that's locally so.......
Gets me every time!!!
@@dananorth895 Big crystals, big gold? I like it.
I have been finding Pyrite/Pyrolite crystals on the beach in large quantities.
I believe there is some gold in there because when I smash the stuff I get a lot of black powder... and large gold flakes.
I have fired the material and hopefully today I will be able to cupel into Portland Cement. Rotsa Ruck Raggy
Best of luck to you.
Your vids are an education, many thanks, when out prospecting I always look for the pyrites especially when still in the host rock then take everything home for processing. Seriously love this channel and have learnt heaps from you, hope all is well with you and will see you again in the next episode
I'm glad you found it helpful.
@@ChrisRalph thanks again, greetings from Australia
I was coming out of the hills the other day and some fellows asked me if I had found gold and I said, “No just pyrite.” They stopped and said, “If you’ve found pyrite you found gold.” I didn’t tell them where the vein was lol 😂
Interesting.
Lol had a very similar interaction a few weeks ago😅😂🤙
I really appreciate your vids. Great info. Great presentation
Thanks, glad you enjoyed it.
Hi Chris, thank you for the excellent videos. It's so nice to hear good information from a professional. I'm also a subscriber to the ICMJ print and digital versions. Keep it up, good sir!
Awesome, thank you!
Very good talk! Nice to see you covered marcasite and pyrrhotite too. Arsenic is often associated with gold, so it is worth watching out for arsenopyrite.
Well said!
very helpful we've had this mineral for many years. this has been the most helpful you tube or links on google! thank you!!😊
Glad it was helpful!
I definitely need to revisit those places I found a lot of pyrite. Thanks!
maybe so....
Great video Chris!
I'm a video game developer doing research for a few games that use realistic mineralogy and your videos have been a big help! Some of what I did before development was educational video direction, so I have small note. While, you have been way better about it in your last few videos, but, I notice you often look away from the camera when talking, if you put your "prompter" above the camera it will really help this issue!
I understand.
I love listening to you while I work. Thank you for your videos they really help me.
For hobby use, is there a breakdown or list of acids relative to each mineral used to isolate specific minerals from others?
My local mining shop didn’t wanna tell me it seems as they were worried about people causing environmental damage from such knowledge. I get that but I just want to do small experiments with my kid to isolate different minerals. Any help would be appreciated thank you
There is no such list because separating things is dependent on what you are separating the thing from. The matrix can be variable.
@@ChrisRalph ok I get what you mean. I pick up from old pirate journals where folks rather hid items in some sort of concrete mix, which seemed to imply being able to recover later by dissolving?
So was curious your thoughts on what might be used to do such things?
I purchased your book and really enjoy and learn from the videos you also produce. Our family owns claims which, historically, produced both placer gold and mixed ore from drift mining. There's a lot of silver, galena and pyrite. After sectioning and polishing ore samples, I can see that there's gold in that pyrite. Most people have learned pyrite is only for fools.
...
I'm recently retired and purchased a nice, mid-range, metal detector, with software tuned for gold. Within the last week, I can finally access the property with my truck after the snow melted. I invite you to make some interesting episodes about the gold rush in Colorado and how to find gold in such a mine field. I'd be glad to show you around Gilpin county CO.
Thanks, but I've no plans to make it to Colorado anytime soon.
Worthwhile interesting episode Chris I really enjoyed it.
Im going yo enjoy this. Kinda been dreaming about feeding beach sand into a sluice lately 😊
Might work, depending on where the sand comes from....
@@ChrisRalph It's really difficult to see through the sand bags at Home Depot 🙃
We also now know REE are directly related to coal deposits and most economically extracted from the ash of burned coal, but has there been any inclination or studies showing gold content specifically related to Anthracite Coal deposits in the Grade A Mammoth Vein in Schuylkill Co PA.?
There are tiny traces of all sorts of elements in coal ash.
Thee ohm resistance test leads me too think of a possible use as a LOAD resistor use. Has that ever been tried in a load circuit?
I'm not sure.
Hi Chris. Thats for the video! Nature is amazing. There is a lifetime of learning when it comes to rocks,minerals and the processes of nature. Knowledge is almost more valuable than money. Or the gold that is found. Although the largest gold deposits found were because geologist did the footwork and usually backed with research paid by people with lots of money. Its is the geological processes that enriched nature with the minerals needed to have the diversity of life on this planet. What a wonderful world we live in.
Its a world full of wonders indeed.
Hey Chris spot on pyrite and quarts have led my self and friends to usually find some gold. But pyrite is beautiful to look at. Cheers again
👍🇦🇺🇺🇸
Thanks 👍 Pyrite is good to find!
Chalcopyrite ALSO develops more of a rainbow hue to it when it begins oxidizing.
This makes it more easy to determine it from pyrite.
One can even artificially oxidize chalcopyrite to cause it to form a beautiful glistening metallic iridescent appearance.
Ok.
Hi Chris, I'm from Papua new guinea in the South Pacific Ocean. How can I find a good gold detector and which detector is best, is it the double figure scale or the single detector
I did a video on selecting the right detector for your use. Take a look a that video and it will answer a lot of your questions. See: czcams.com/video/SqwkpH9LZIM/video.html
Thanks for video/ demo!
My motorcycle was just stolen (second time in 2yrs).
Can you do a diamond blade test & a hammer smash/fracture test? Thanks
not sure what you mean by a diamond blade test. Can you explain?
@@ChrisRalph I was commenting on a different video. The video ended,while typing & you received the comment.
Both videos were downloaded- a testament to my interest in both!
Thanks for great content!
Thanks for another great video. I was really hoping you would show the fine Au on pyrite with either a microscope, or SEM. Would have really liked to see an example.
I don't have a picture like that to show. Maybe you could find something using google.
@@ChrisRalph I did find 1 picture of a tiny grain on a 1mm cube. University of Otago picture, FYI. It was hard to find a picture. I found a nugget growing out of a cube once, but lost it into the carpet.
Thanks Chris very informative.
I once had over 30 m3 of granite quarry rock delivered to one of my work sites. We saw lots of metallic colors and when we consulted the department of mines we were told it was pyrite not gold at a glance but we're also keen to know where it came from.
Now I wonder what if ?????
LoL I think I'll just get myself a minelab gold monster and go to the gold fields. Cheers 👍
As I say in the video, pyrite is common and occurs in lots of types of rocks. Gold is rare.
I'm still learning and have learned a lot in the past couple years. Watched this because my wife found what looked like a Moss agate with a small patch of what looked like gold. Kind of looked like foil. It's in the tumbler right now. Hoping the patch survives because it looked cool. My question is, if it is pyrite, can it be shined and how to do that if it oxidizes? Great video BTW.. thanks.
Pyrite does not form as foils. Perhaps it is mica (which forms thin sheets)?
@Chris Ralph, Professional Prospector well I guess we'll find out lol. Mica doesn't do well in a tumbler
Thank you very much..
You are welcome, glad you liked it.
Great info and much appreciated however , Where does the golden Pyrite come from as I purchased a 4" piece that actually had same color gold color that were actually quartz crystal forms , only as stated the same dark gold color .
Wondering if this was aan made coloring or if it is real !
I also have the greyish cubed formations as well as just small unnoticeable formations .
Any info on fake made Pyrite ?
Thank you for your input and expertise .!
From your description, I just can't say. Never heard of man made pyrite specimens.
I have searched for expert knowledge of someone in the field and found your site !
The piece I acquired looks like quartz crystal formation and not square ones that are normally found ., plus it is a brassy color and uneven smoother bottom. . Was thinking that someone with abilities to somehow color the extremity with metal ??? .Also where does gold pyrite come from ?
Should I take pictures of it and send it to you ?!
Hi from Australia. 🇦🇺
I'm finding your segments very educational on a basic beginners level.
As that what I am.
I'm involved in a Astronomy Club inwitch has geology group with in the club itself inwitch are out in the field once a month searching for fossils, minerals & crystals.
I would also like to ask permission to run one of post leatchers while discussing Pyrite's.
Would this be OK. ?
sorry - I have no idea what "post leatchers" are.
Dude your the gems Ive been prospecting for ❤ these videos are absolutely excellent and informative.
Thanks, glad it was helpful.
I have been searching an exposed quartz vein with beautiful mineralization along with pyrite.
Best of luck to you.
Hi, my husband did a contract work at a mine in Northern Canada. Since I love rocks and minerals, he brought lots of different rocks containing all kinds of pyrite. I would like to send some pictures to you. Some are the normal cube crystals, but some look like molten metal on chalcedony, quartz, and metamorphic rocks as well
Thanks for sharing! Just based on your description, I'd have no idea what the molten metal was.
Howdy, My name is Dean I have a specimen of what I think is gold/pyrite in quartz. I'm probably wrong I usually am. My question is may I send you a picture of it some how so you can maybe see and tell what it might be? Thank you so much, and thank you for your videos very much so.
Sorry - I get quite a few people every day who want me to ID their rock and mineral photos. I do not offer a mineral ID service, mostly because it’s not as easy as you think. Usually, minerals cannot be identified from just a picture. Please watch my videos on how to Identify minerals for yourself.

I’m new at looking for gold in rocks as I’ve been doing placer prospecting so far! I’ve brought some rocks home, cleaned and sitting in pail of vinegar. I’ve been told to add salt and boil for … (no one said how long) so going boil dry (outside on burner). Gonna crush fine. Then pan. What’s the easiest way (chemical to add/cook) to liquidate gold then how (what?) to solidify free gold again. Yes I saw how the sulfides will drop gold for iron but how to do that without chemistry lab? I’d be doing this outside. Thanks in advance, Laurie
There are a number of sites here on ytube that show how to crush, refine gold, copper etc.
Commercially, dissolving gold involves the use of cyanide. The best way for the individual is to crush the rock to fine sand and pan out the gold particles. I have a video on how to do this.
Mount Baker Mining has done some videos on processing Ask Jeff Williams ore.
Excellent!
Glad you liked it!
Thanks I learned a lot about Pyrites cool.!
Glad to hear it!
There's a lot pyrites here in my my place,its a vain down ward its look like a gold.is there a possible that there's a gold down there?
It is possible there is gold but no guarantees, it is also possible there is no gold.
Great video.
Thanks, Glad you enjoyed it.
I have a question about pyrite, a few years ago i was digging up a spring at the head end of my farm pond with a spade and pick ax and had a lot of pyrite flakes coming up and also a film of almost oil film seeping up.
Does the pyrite flakes and the floating oil/rainbow color film coming up indicate anything special. Oh and also wanted to say my soil is heavy clay, hard packed.
Pyrite does not come in flakes. My guess is that it was likely mica, which almost always comes in flakes.
@@ChrisRalph mica, is that gold color and shatters easily
Mica is frequently gold colored.
I’d love to have your book can I use your lessons in an outdoor class I’m starting with 12-16 age group?
You can tell them what you've learned, but you can't make copies of stuff from the book.
Thanks from Australia have your book
Thanks! The book should be helpful.
Thank you for this video. Very educational. I have a question about a type of rockI have found. Is there a way I can send a few photos. I really would like to understand more about it.

Thank you for responding, I can only imagine the pouring in of peoples discoveries and questions if that door was opened. Thank you for the dedication you apply to your videos, you certainly are an educator, bringing a vast area of complex subjects, all together, to make sense to common average person.
I understand, I can only imagine opening that door. Thank you for your time and dedication that you put into educating the common average person, with an enriched college course education in a 30 min utube video….
Have you ever researched the Llano uplift?
There is gold in the Llano river, its very small particles, but its there. Do some research on Google to find out more.
Can you assay pyrite sulfides for gold percentages that are encased in the pyrite?
yes, a fire assay of an ore can determine the gold amount in the pyrite.
@@ChrisRalph Does roasting pyrite sulfides free encased gold so it can be viewed?
Through roasting can oxidize the pyrite, but further crushing will be needed to liberate the gold. Remember that panning may not capture the very fine and microscopic gold particles.
Good Information
Thanks, glad you enjoyed it.
Hay Chris I was wondering when you did the side by side comparison of the 3 metal detectors. You had the Minelab and the and I'm thinking the Garret but I couldn't understand the 3rd one. Can you repeat all for me. I'm thinking the Minelab was the 9,000 or the 8,000. And I can't remember what the Garret was called. I guess I'm just getting old and decrepit.
2 of the three were Minelab, the other was the Garrett Axiom.
@@ChrisRalph Thanks Chris. I'm taking it was the top two Minelabs.
Good man yourself Chris thanks for the nice lesson again!
My brother and I are known as the pyrite pirates, which I’m not proud of😂
That is funny - the pyrite pirates!
I live where the industrial era began, they dumped their waste everywhere, this area was once considered the most diverse area of outstanding natural beauty. Alfred Wallace discovered evolution on the mountain I live on as so many different ecosystems existed in such a small area. Copperopolis - what a dirty word. They say we should be grateful for the jobs but all we got was pennies, several families sharing small damp cold houses, kids working in the mines, hilltop graveyards from the various furnaces, cholera.....they used to have police guarding the mine waste, but they just eventually turned it into orange bogs and call them nature reserves!
certainly a very interesting story.
I have been finding large solid chunks of pyrite in our rejects from our coal mine. some is very loose bonded crystals and crumbles but i have been finding pieces that are almost as solid as steel very dense and large pieces from a grey white colour to a golden yellow and everything in between. Whats going on here?
The sulfur in the organic materials which formed the coal have combined with iron from the ground water to form pyrite.
@@ChrisRalph thanks Ralph! That would explain the density i guess. Its nothing like the stuff ive seen in hard rock copper/silver ore . Could there be metals other than iron? Some of it almost silver. Im thinking possibly arseno pyrite?
Tiny traces. No other metals worth extracting.
This video has helped me identify what I have! A have a specimen I found in Oregon that has copper staining sandwiched between two quarts veins but has geometric chalcopyrite /pyrite shapes I wonder if there is gold in it. (Known area for gold)
Beautiful specimen imo
Its possible there is gold in it.
I need your assistance in Zambia
May you able to come
I appreciate your interest, but I do not offer any services for personal training, consulting or advisement. I get many such requests and simply do not have time to help all who ask. I have many business and family commitments and simply don't have the time available. I do wish you the best of luck, but I am sorry that I cannot offer any help on that level.
i only got a spec of gold learning about my dry washer. i have only used it 3 times. was a nice day with the first class miners. have a good day.
Hope you have more success with your dry washer in the future.
@@ChrisRalph so do i always have to learn. have a good day.
There's so much pyrite and mica here in CO that it litters the creek beds and ground all over. Your shoes will be covered in it just hiking around.
Too bad neither is very valuable.
Pyrite , Devils Dice, are fun crystals, as is fossils. Basically a metal detector will not pickup pyrite, this is a good way to test if it's metal or crystal if I'm not mistaken pyrite is metamorphic eventually turning in to iron. Some of my gold nuggets have both pyrite and iron. Interesting iron expands 10 fold when it enters another metamorphic stage turning to rust, which is why many of my gold nuggets have holes and turned orange due to iron oxide. Iron oxide is a super fine dust which penetrates and is trapped inside of gold nuggets. Chris I would love to see your fossils and the one's that consist of pyrite. Your anology of my conception is important to me. Thank You! I'm Curious if your metal detector picks up on your seashell of pyrite? I supose if the metal detector sounds off on the seashell the seashell is exreemly heavy.
The pyrite doesn't always expand. I have some cubes that are exactly as they were formed - just the iron sulfide of pyrite is converted to iron oxide. metal detectors will not pick up pyrite - its not conductive enough. Metal detectors pick up metal because metals conduct electricity.
Thanks Chris, Yes , Like a electric guitar, the pickups on the electric guitar are electrically charged and sense a disturbance in the vicinity of each pole on the pickups, the metal strings vibrate at different pitches and wave lengths producing different tones. Metal detectors have a coil instead of metal poles which electric guitars have. Yet the guitar poles have coils of wire windings around them, as you may already be aware of. Crystals are amazing and produce different colors just like glass when small amounts of different metals are added to the molten glass to produce different colors of glass. Thanks for indicating that just the iron sulfide of pyrite is converted to iron oxide. I had the assumption the entire crystal turned metamorphically into metal iron, then the metal iron turned to rust, at this point expanded 10 times it's original iron metal size and then metamorphically produced a bi product of rusty orange colored iron oxide dust. I was thinking iron sulfide is rust. I hope one day you will get to see my gold fossils of various different creatures and or parts of various different creatures. They were formed into gold while clinging to hydrothermal vents, or they were already metamorphic stone fossils at the vents when the gold accumulated inside them as underwater volcanoes elevated the sea floor creating coral reefs. Most of my gold fossils are of seashells exoskeletal and crabs also exoskeletal The other's im' not sure what creatures or coral plant, worms they are. I think the natural exoskeletal round shape's of seashells helped the gold to accumulate something like a man made crucible works. Gravity seemed to allow the gold to settle at the bottom half parts of the natural bowl shaped exoskeletons crucible's.
Great episode! 👍 ✨️🍻
Thanks!
@Chris Ralph, Professional Prospector only took a freshman geology many many moons 🌙 ago...great explanation of sulfates 🍻
I used to work on Admirality island in Alaska and this stuff was everywhere. It would turn the water reddish orange. I used to have some great examples, but lost all my treasures years ago to a storage unit I couldn't pay the fees on..😒
That is unfortunate that you lost them.
@@ChrisRalph Yes it was, but I did learn a great lesson about possessions, I'm not so connected to my "things" anymore. Can't take them with me anyway.. God bless you sir!
hello teacher, you are an important program for us, please provide a Farsi translation We are watching your program from Iran
I do not speak Farsi. Try automated translation.
I find Pyrite very valuable as it is a nice common source of sulfur 53% while Galena is only 13%. Obviously any slag left over after the two pot distillation you can use however you like. Now i like extracting the sulfur because it is apart of a recipe for non smokeless gunpower and i do have a muzzleloader, the recipe ingredients are as follows
Charcoal
Sulfur
Saltpeter
Now the funny thing about saltpeter is you can extract it from your own urine but boy it stinks, it's like making compost really but you are not gardening and you don't want sunlight to hit the beds. The process for Saltpeter is about 7 months in the south and about a year up north as the more heat in the climate the better.
Like other than mixing the powders and such the only real dangerous part is the sulfur extraction as you don't wanna breath in H25 for those that don't know Hydrogen Sulfide. It's highly toxic, corrosive, and flammable. You could also use Sodium Thiosulfate in the 2 pot distillation as it is 40% sulfur and since it is already pretty much crushed up you don't have much wok to do. Funny thing is you do heat up Sulfur with a few other things to make Sodium Thiosulfate in the first place, and Sodium Thiosulphate is used to treat cyanide poisoning allegedly -i don't remember if that part is true or not-
So anyways yeah Pyrite will always be valuable to me at least and anyone who owns a muzzle loader as again it is just a nice source of sulfur that is naturally occurring.
Though as you are explaining after the sulfur is extracted if you had a good bit of crushed up Pyrite might as well extract the gold if that was remaining and not contaminate the sulfur in the other pot
Or you could just buy and store a sufficient amount of sulfur and Potassium Nitrate. It would be 100 times easier than pyrite distillation or urine processing.
@@ChrisRalph That is true, but it is just a hobby i occasionally do when i truly have nothing better to do
Pyrite the one thing about pirates or fake gold if you take it in the dark it don't look like gold you take gold in the dark is still shines
There is that.
Ok now I want to go find some Pyrite !!!!!
Good video on that hydro pit exploration.

used to find it in Illinois, ( and we called it fools gold) the only fools we're those like me that believed those older then us who said it was not worth anything. only to learn years later that YES YOU CAN RECOVER GOLD from iron pyrite. those whot told us to throw it away, collected and melted it
Some pyrite has gold in it. Some does not.

Pyrite mining goild 2023 2080 👍 1kg 90.13 gold 1kg 30.21😢
You say it
A question i have is that in reference to a study in '03. This study focused on The Lodestar prospect in eastern Newfoundland, Canada. It went on to conclude that "Gold is “homogeneously” (i.e., no nugget effect) contained within the structure of arsenopyrite. Other sulfide phases, such as pyrite and chalcopyrite, contain very low levels of Au. Gold contents in arsenopyrite from individual samples, and even within individual crystals, do vary, presumably related to arsenic concentrations. As gold was not observable by any of the other micro-analytical techniques, it must be chemically bound in the arsenopyrite structure, thereby classifying it as “invisible” gold." With that stated, is that a to also mean gold content in a sample is directly related to the amount of arsenopyrite in a sample ---> no matter the location, or is this specifically at this deposit only? pubs.geoscienceworld.org/canmin/article-abstract/41/2/353/13543/A-LAM-ICP-MS-STUDY-OF-THE-DISTRIBUTION-OF-GOLD-IN
Sorry, I've no time to study and review this reference paper for you.
Understandable Sir. That's why I summarized the conclusion of the study for ease of reading. The study concluded that Au was directly related to the concentration of arsenopyrite and that it was homogeneous in every sample and every crystal and that the concentrations did vary but we're in direct relation to the concentration levels of arsenopyrite.
My question is does a study that concludes something such as this, conclude the results for arsenopyrite no matter the location? Since it found a direct relationship to the higher level of arsenopyrite meant the concentration in the analysis of gold also was higher... So is that geologically certain across the globe? Just wondering from your experience Chris. It would mean a lot to get a better understanding of this specific relationship if you have any experience or understanding of this, that would help out my prospecting business alot. Thanks Chris.
@@kylestrokelitus360 that's an interesting question because so much is involved with minerals being concentrated. Minerals dissolve and precipitate out again, depending on so many factors such as pH changes, temperature changes, pressure changes, etc., that drawing a single conclusion for a variety of environmental options is risky. I'm afraid many fortunes have been made and lost drawing conclusions when so many different options are in play. Good luck with your venture.
Thanks.
