I enjoyed this video and look forward to more on the subject. I would love to see photos or sketches during your explanations to further illustrate the different ore forming systems and the ore specimens themselves... that would be fantastic!
Great great great video! And I recently bought your book, “Fistfull of Nuggets “ I’m 100 pages in and I’m very impressed with how well written the book is. If I had no interest in prospecting I’d still read this cover to cover. Really appreciate you for sharing your wisdom 🙏
@@ChrisRalph Thanks for your feedback. Yes, I agree, I have found gold along mafic dikes in both porphyry and orogenic model terrains. I would suggest that metal detector enthusiasts out looking for bonanza gold, care more about a rock to detect than a geologic model in their head. Are deposit types what appeal to a Prospector or, more to the geologist and mining engineer? Most folks I've seen in the field want to be shown a rock carrying bonanza gold...
My gold ore video has some info on tellurides, including Sylvanite and Calaverite. they occur in some districts, but not randomly. Glad you enjoyed the video.
We have an epithermal lode at the Ochil hills here in Scotland. Some nice gold count in my pan. Still can’t find the source though I am still learning a lot and will go back with more knowledge and check contact zones etc
Thanks Chris, it’s a small mountain range on the highland boundary fault. We have basalt, diorite, porphyry. Nice coarse gold, I found Jasper, agate and part of a geode 👀 got to find the source of the gold though lol any pointers?
Would love to have seen an example of the gold sample there and where to actually try to find it in this type of area. You are so knowledge in this, but I am new to it and do not understand all the information at one time. I do appreciate your sharing your knowledge with anyone and everyone. Thank you Chris
Thanks for the theory, much more helpful would be to know how such types of deposit’s look like and how to indicate them or what characteristic indicators you have to look for. One at the time. I wish to have more detailed information.
What you ask is a fairly complex question to answer. Deposits in the ground vary depending on what type they are. The greenstone belts of Western Australia or West Africa look much different than the intrusive related deposits of Alaska, USA or the epithermal deposits of Nevada and Mexico. I'm trying to do up videos on topics where one does not need a geology degree to grasp, but there are plenty of technical papers written by geologists on the internet for those who want more detail.
Thanks you so much i have been looking how gold is forming next to a vein im in Australia and have been sampling the vein with low gold but 10 feet up hill gold and nuggets. There is a brown and red zones .thanks heaps
Hi Chris , When you say epithermal deposits are formed near the surface , can you define " near " ? Do we have a defined zone like 10 feet or 1000 feet etc? Quarter mile ? etc ? Thanks !
Epithermal deposits can form at depths from 10 or 20 feet down up to 2500 feet - it just depends on the geometry and geology of the deposit. Most probably form at depths of a few hundred feet.
Your knowledge is appreciated. What can you tell us us about tertiary river deposits..rivers of gold? Wow Nevada outback hems been their several times.!$
Hello again Mr. Ralph. Watched a horrifying video of south African miners crushing rock in a bobby mill. Was curious if it isn't common practice to rig up a large pestle attached by a hinge to a lever on a tower operated by a thong or gear reduction, although I assume the latter would have issues on the down stroke. It would need a little stabilizing like a bottomless oil drum, of course. Just wondering if this is a thing, or if not, why? If you have the time. Thank you for all the information.
Not really sure of your question, we may have a language problem or maybe you are using too many local slang terms for various things. Enough is lost in the translation that your question is unclear.
@@ChrisRalph Ha, sorry, I speak English. Was wondering about making a large mortar and pestle that is lifted by a lever on a post if you can't afford a jaw crusher. The pestle stands straight up in a tube of some kind and a lever lifts it by a hinge. It would weigh over 100 pounds in my imagination. I'll probably just experiment with it when I have the materials and tools, but wondered if others had already been there and done that. Thanks for the response.
I've seen drawings of miners who made a mortar and pestle like that. It would work, its just that mortar and pestle is a lot slower than a jaw crusher. Slower, but its a lot cheaper too.
I was hoping you'd start this series with pockets. We have 660 hectares of claims that have been described as epithermal. The problem is, the big boys want nothing to do with it because it would have been hard to find the enriched areas they think are there. But I have a feeling there may be a pocket or two.
That was just the beginning. More pocket related stuff is coming. However there is no magic technique that finds pockets in all cases. Metal detectors cover a lot of ground and can see below the surface what your eyes cannot see.
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. Part 1 can be found here: ua-cam.com/video/MpkW58ZeQlc/v-deo.html and Part 2 can be found here: ua-cam.com/video/zOWo49X90gA/v-deo.html and Part 3 can be found here: ua-cam.com/video/_ab5NngRlVw/v-deo.html - Those videos should answer a lot of your questions.
Have rediscovered an old partially developed lode mine. Adit 150' long, 1/2 oz. ore. Lode traced for 1 mile on surface. Adit in ore averages 2.5' wide, up to 20' wide. Shaft in ore down 350'. Do the math. Open on strike and down dip. In slate. What do you charge for consulting type work? Huge ore reserve.
Hi sir, i am from turkey, we have 1800 hectares potential gold research license in turkey, hope to see you in our area to get your ideas, is it possible to contact with you
Sorry, I get many, many requests for help, advice, mineral ID, etc every day. I could spend 10 or more hours every day meeting all the requests. So I only offer the videos and the book.

Thank you Chris, great information hope you do more on the subject of Greenstone and BFI type deposits.
I'll keep that in mind.
Another great video full of information Chris. Thank you for sharing your knowledge with us.

Thank you for the very kind words. I hope you are very successful in your quest for gold nuggets...
Great information Chris, thanks for taking the time to do this series, much appreciated...
Thanks Chris, good summary of deposit types for Bonanza Coarse Gold. I would also add mafic dikes / ironstone and their adjacent quartz veins.
These are a sub-type of orogenic deposits.

My gold ore video has some info on tellurides, including Sylvanite and Calaverite. they occur in some districts, but not randomly. Glad you enjoyed the video.
Excellent talk Chris !! This is great ! Thank you ..
Thanks a million Chris I love your videos going to get your book talk to you later
Sounds good!
Thanks for the information. Nugget Shooter shared your video, otherwise I wouldn’t have learned about your channel
Bill is a friend, we are going to do some videos together later in the summer.
This is brings some things to attention for me ,for sure. Always you have great informstion sir.
Glad to help

My ESP is not working, and my crystal ball is broken. So knowing absolutely nothing about your location, I really cant suggest much.

I'll probably be back there this spring sometime. I'm glad you enjoyed the video.
Next time you find one of these pesky pockets you call me.... I’ll get rid of it for ya! 🍀⛏
Sir Chris thanks fir sharing vedio full of information...Plz also post vedio on Gold bearing rocks ...

Can you please do a video on the gold and other deposited in the Holcomb valley ca? Please
do some research and join a club with land at Holcomb valley.
Your knowledge is appreciated. What can you tell us us about tertiary river deposits..rivers of gold? Wow Nevada outback hems been their several times.!$
Thanks much, I should do a video on the tertiary river channels. Good idea.
Hi Chris
Do you think large gold nuggets form in the mud pots?
Maybe why there is no quartz on the large stuff.
Formation is deeper down in the earth, not the surface mud pots.

If gold deposited last, can that happen in the same vein deeper below sulphides?
Its possible....
Im getting your book
It will be back in stock soon.
Sir how to cleaning hard rock including pocket gold
All type Gold clinging level video sir.
Sir, we have a language problem. Your English is unclear and I do not understand your meaning.
Hey Chris great video, thanks ! Which countries in Africa did you prospect?
Burkina Faso, Mali and Cote D'Ivoire.
Chris just curious are you the one that drilled and blasted some Pockets out in Nevada.
I've been hunting gold for 40 years.
Its been years since I did any blasting - so I am guessing I am probably not the guy you are thinking of, but maybe.....
Yes I'm talking about years ago trying to figure out how long ago it was
Some where around ten years ago.
