Gold Prospecting & Sampling Old Gold Mines For Forgotten Gold
Vložit
- čas přidán 7. 09. 2024
- Prospecting and sampling old mining claims and dump piles for gold values that may have been overlooked when the price of gold was lower. Bulk testing and sampling gold ore is an important part of gold mining feasibility and profitability, but is often over looked. This video shows how to use MBMM equipment to carry out a bulk sampling and testing plan.

I used to go to an abandoned mine up in North Carolina. The tailing piles there were mixed with low grade and high grade gold ore. They did mostly take the rich veins out the ground and tossed what they thought was low grade in piles outside the pit. I've found nice pieces with wire veins running thru the quartz. It was amazing what the old timers left behind.
gold mining 101 for anyone who wants to pursue this avenue of gold recovery. Well done and comprehensive!

Thanks for the shout out. Finally getting close to running some larger lots through my smaller scale crush and sluice system (100 to 300 pounds).
Nice, look forward to seeing them. If you ever get out and pick up some of that matte you mentioned and you want to send up a sample let me know. That would be a fun video and cool to see what the old boys missed.
This is your best video about your equipment you have done. The clear way you described how to start out, get some cash flow going, then to purchase additional modules, and how to fine tune recovery, is absolutely precious. It all makes sense the way the way you describe the process!
This guy is straight up living the Factorio life. Fun to watch.
Not enough iron plates :)

@@malcolmanon4762 why do you say that. Please share your knowledge Malcolm
@@vandamned6979 OP is referring to a game called Factorio (resource / production sim), one of the in game memes is not having enough iron plates :)
I didn't know prospecting tailings was so interesting. I can't believe I watched it until the end! Great info, thank you!
I've been trying to learn as much as I can about the Gold mining industry !
I worked as a Millwright for 40 years in the Zirconium metals chemical extraction and manufacturing industry, so I'm familiar with the processes and equipment you use. I have to say that your presentation was absolutely a joy to watch ! New to Gold prospecting, Metal Detecting and finding my own, I have managed to develop a reasonable idea as to how the processes are done and the work involved. Sadly I'm retired and beyond my years physically to indulge myself any further than learning about it !
This video and your "Excellent Presentation" has me inspired to learn much more !
I've enjoyed watching and look forward to more. Thank you, my time spent has been most worth while !
😉😁😎
I appreciate you and your positive outlook on learning. I suspect you were a real asset to the company you worked with. Thanks for the post.

May you tell about zirconiumextraction more? I currently study this topic and I am sure that you mat tell something that it is not written in books. Thank you.
I'll help you
Flux solution ?
Wow! I just learned a lot on new information about assaying, classifying, and smelting. Great presentation, well paced and informative so that the novice and the professional alike can benefit from it.
Thank you!
Excellent video Jason, I think probably the best one yet. The metallurgical and mineral economics angle are so invaluable, especially in combination with the sampling and assaying work as always. This is brilliant stuff, and will be so useful to so many people. Thanks for sharing. If we can only go find some mines capable of providing 20gpt feed for a few years! :)

More knowledge about the entire process than years of college and experience. Ty for the best information I've gotten in my 15 years of mining.
I think this is one of the most informative videos you have ever done. The chemistry for cupelling is the best anyone has ever put out. Please think of relaunching this video for subscribers who have recently started viewing.
As a long time union millwright I recognize some excellent engineering and superb work that you've done setting this system up.

Your vids r so long i need to watch 3times to get all info i love it sir you a real tuber (you tuber)
some say Fred Dodge is a master of gold recovery, and a great resource and friend to have . you can never know too much .
Great speaker, doesn't waste any time. I didn't know chemistry and math and logic was such good tools
I think this is your best video yet from an information standpoint. Thank you, it was long, but well filled with information.

Thanks Kieth. It was long, lots of info though :)
@@mbmmllc Sometimes it is a tough call as to leave it in one piece or cut it up. Hope things are going well with you. I used to live at the Birch Bay Farmer's Market for years. I loved the area, but had to follow the money. Great memories.
@@mbmmllc it's an investment & spendable with legislation in different States & having a K-exchange. I sent you my link about some from my Federal international gold bullion bar Bank
Felt like I was back in my mineral processing class and lab. Great to see you work through the full example. Including the grade / gradation calc which would have been graphed in our class
This was quite entertaining for me this Sunday morning
Great job, Jason! So much important information was covered but I kept asking myself: "What's that new piece of equipment cost?" Maybe just add to your list of links an equipment list with approximate costs of each. Thanks for all the work getting this post organized and filmed.
The crucible incident is a lovely work of art!
I really learned something watching that video I've been having problems with my smelting process I'm going to try it this way all I really need is a shaker table now
I don't want to hurt anyone or myself.
Thank you !
Science + mining = fascinating topic!
you sir are a PROFESSIONAL! thank you. i will never go beyond panning, i do enjoy seeing what i am missing.
Way to munch my broken old body wants to do with these as the numbers look not that bad. Thanks for a neat post bud.
Something i found rehabbing an old gold mine was check the dirt under the tracks in the main haulage way. Many old mines that used end dump ore cars had small amounts of fine ore fall out of the cars on to the tracks.
this ore was ground under the wheels of the ore cars.
if the mine had water flowing out under the tracks the light weight material was washed out and the gold was concentrated under the tracks.
the last mine i ran the ties had rotted but the rails were still good. so we lifted the rails and removed the dirt under the ties and put in new ties with mill sand to bed the ties. i ran all the dirt from under the tracks and found it ran about 5 times the average ore grade run from the mine
on my impact mill all the discharge went through a circular vibrating screen separator.
everything bigger than 80 mash went through a back through the impact mill.
Roasting of the sulfur will be needed for better recovery. When you XRF the beads they should be flattened out a sheet to get the most surface area. When the assay is done only 19 grams of materiel is used after fine grinding of the lot sent in.
Just wanted to say I'm new to the channel and loving what you're doing. Very informative. It's something I'll probably never get to do but I still love trying to soak up the knowledge you're sharing about the process. Mille grazie!!!
Wow man, what an interesting video. I had no idea about most of this stuff. I like how you went from raw material to separated metals! Amazing.
You are one smart dude. Thanks so much for your detailed explanation. You actually know the science!
Back in the 80's I worked in an assay lab in Kalgoorlie, Aus. My job was to weigh up samples of tailings before they were fired through in the kiln room. Thanks to this video I now know and understand more of what I was actually doing all those years ago.
Where was that I used to get assays done at Genalysis, now in Maddington. In like Flynn was the manager.
@@ianburton8050 Sheens Analytical, Hay Street, just along from the knockers :)
@@allwrighty100 Now...If they had a pub in the same street would have saved a prospector a lot of running round when he came to town.
22:44 since matter can’t be created or destroyed, some gold is certainly somewhere in that pile of mess! Thanks for sharing. Chemistry is amazing.
This was off 250kg, very small scale. If the ran 8 tonne a day at 1 tonne per hour obviously he would get alot more. But yes it's alot of work for fuck all. Haha
You can change your mass units from g to mg , on the balance, to weigh smaller amounts of sample more accurately.
Nice science lesson in there! Sorry to see the broken crucible, but thanks for sharing the failures as well. Good luck building some nice lifting and pouring shank in the future.
Jason, yet another gem of a video ... well produced and your explanations are so good, I think I could smelt gold from ore ... but I won't ... LOL ... Please keep producing these. Thanks again.
You are great! You full of great knowledge that I’m sucking up like a wet sponge! I run a great channel dealing with gold and high grade concentrates, and I wonder how many pounds of material I threw away not knowing this step! I do have about 20 pounds of hi grade Crushed gold ore and need to process it ASAP! Would love to collab! Thanks for the info!
on the Lost Mines channel, run by two Welshmen who explore old abandoned mines around them, they mention that some scrap piles were "salted", I think they said, with exceptionally good ore, in order to attract investors, therefore one should be careful to judge a mine's current state of richness based on the top of the scrap heap. But it looks like you got more than just the top bit here!
i thought this is one of your best videos. And they are all good. This one is real educational.
Your math and back of the envelope calculations are priceless. Wisdom is better than fine gold. Although wisdom can clearly lead you to gold. You Rock brother. Thank you very much!
Another great video and info, Jason. Such a real world basic breakdown of our options. Quick question about the Borax and Lye. If Borax is acidic and Lye is a base. Do they neutralize each other? Thanks!
Thanks for a great, thorough and entertaining video. That dump grade is extraordinary, and hard to believe at around 20gram per tonne. Where I am the old miners originally processed at about 15g and left at most 5g in the mullock. So that process would only break even on 5g mullock.
No one responds, he said 3 to 4 grams a tonne in the end
Totally awesome! Very good explanation and presentation of the processes used. Felt like I was back in college in the 1970's. Thanks for making me feel that young again! Thumbs up and subscribed. Look forward to catching up on your other videos and to those in the future. Keep up the good work!
limonite! good quality! this! is a good sign of a interessant gold deposite.
I like the fact that you put the accident in. I think a lot of people would have left that out. Very good!
Enjoying the longer videos.
Keep up the great work.
That was an excellent breakdown and even a good investment for processing tailings at today's prices! Kudos!
Wow nice presentation. You spent some time putting this demonstration on. Thanks for the time and effort!.
Excellent video! Yes, you covered alot of ground in this one. Your content is top notch.
Nice presentation
Real informative
I agree with Keith, your best video yet. Thank you and please keep the videos coming.
Watched every minute! Very interesting!! My Dad always said if you LOVE your job you don't work a day in your life!! I'm probably not going to do what you're doing, but I'm getting things ready to do ewaste and karat gold recovery and refining!! Maybe even do some panning for gold to see if I like it or see if I can do it!! Thanks for a GREAT VIDEO!!
Have a GREAT Day!!!
My wife's uncle invented the term "E-cycle" even has the name patented. It's a facsinating process of recovering metals. Good luck if you ever make the venture!
In my country there are a lot of quartz rocks that contain metals such as gold, palladium, copper, silver and so on, we often do traditional gold mining so that the gold we get is mostly gold that has been separated from its mother and is scattered in every river, while the gold that is still mixed with other metals in the quartz we throw away because we do not have the knowledge, support tools and also money as a means of supporting our mining.
Love your content. Every minute of it.
That is a really awesome system I enjoy how smooth it operates.
I would love to learn the ropes and devote my life to gold recovery.
Wow that is very nice set up and great way of doing things I have been enjoying the video thank you sir!
Your operation has changed a lot in 4 years. The shaker table is the only thing that looks the same.
love you bro. am watching you been very long days.god bless u.
21:40 _"So, . . . Darn."_
LOL
24:30 Right after a breakage catastrophe caused by lifting a crucible with Channel-Locks, I can't believe you grabbed that brand-new crucible with Channel-Locks!
I love the way you not only explain the process of recovering gold from ore, but the financials of the process.
Fantastic Info.thanks for your in-depth efforts my recovery increases almost every time I employ and master your teachings.thanks much one day I hope to be able to afford your processing system.
I really enjoy seeing the molten colors.
Agreed!
Superior video and explanations. Thanks, Jason.
Ok I have one question.
Your hammer mill, did you check it for potential gold residue from previous uses before you processed and or did you check it after you processed the tailings for lost gold residue? I say this because in previous videos you processed some pretty good tailings which if I remember had visible gold which might just ball up and never lever the mill.
Maybe your machines are so good you do not need to I’m not sure but I would do both before I ran assay tests if I was looking to operate a mine or process it’s tailings for my livelihood.
I’m not being critical it’s is the process for good data recovery for mine economics.
If I had a mine your equipment would be there. Keep up the good work.
Great observation! free gold loves to accumulate in the milling equipment, times ten if using a ball mill. When performing maintenance clean up the milling equipment and recover the sediments for a nice payday.
Best episode yet Rigby. Thanks for all the information. Is there a waiting list for the guided tours?
8:20 for you novice prospectors, an 'assay' is just when you take it to another dude for a second opinion and you ask him "watchyoh assay? "
On the PLUS side your spillage makes a magnificent piece of gold mining Poster Art! : ) Whilst watching this informative footage I spotted something which told me where there's historically been gold smelting in Glasgow. Yesterday, when looking at very old maps of the city I realised something that ALSO told me where gold mining had taken place. I think this is what happens if we immerse ourselves in a topic. You start to Recognise & Realise.
Love the videos man! Just curious.. if one did have sulfide concentrates containing a lot of copper, what process would you use? Copper as a collector, then electrolysis to remove the copper? I think you should do a video on that if you are able to! Keep up the great work man.
Wow. I wish I wasn't so freaking old. Good work.
This is certainly your best video to date from the perspective of a potential small scale operator. It's more comprehensive which was lacking in the past. At the end you touched on the economics of a complete operation, and I think that subject ought to expanded. Perhaps you could focus future videos on this and talk more about the ancillary equipment needed to round out the whole milling operation of a mine.
I think my head just exploded, but man do I wanna go gold mining.
He’s got the chemistry part down pat. Seems like it could be a pretty simple process once you get it down. At first I had a problem absorbing the information but after his explanation it makes a bit more sense. I never new this was a process I always thought guys just panned for the stuff and picked it out by hand lol.
This video is golden thanks to the host.
Nice Approach to analysis for rare metals !
Wow, super cool. What I liked most was that you did not need to use the nasty cyanide leach process to get an excellent percent gold recovery. Also, and once again, patience & good practical technical knowledge win the day!
Excellent video....your knowledge and comprehension just shines and you're able to articulate and explain it all. A great teacher. Thanks for the calculations and relating it to the big picture.....my father worked for a German Precious Metal Refinery in Canada....apparently the apple not far from the tree, hehe....thanks for the great relay.
The discrepancy in the tailings analysis can be due to the residual silver in the Pb. With such a small amount of silver the measurement error can be large in either direction. Most likely, you've overestimated the amount of silver in the lead. Great video! Thanks so much. -- Dave
I used to work old Placer creeks in Montana just for fun. It always seemed logical to me as these creeks continued to cut into the rock, they would continue to yield, but they were "panned out" a century or more.
Absolutely fascinating, I sat with a bottle of beer and learnt a ton 👍
This is another reason I like Bitcoin. No matter how high the price goes and no matter how high the Demand goes, there will never be more than 21 Million Whole Bitcoin ever mined.
28:00 Oh, we have one of those in our lab.
Very informative and interesting at the same time. thanks
Thank you for another great video! Keep up the good work and be safe out there.
Love the smelting and the educational tour you give everytime ❤......great video....
Love your videos; they are full of so much knowledge! I am learning a ton! Thank you.
I love the explanation of how it all works!
When your smelting the lead tip in the oven, Where does the lead and other material go? why does it leave the gold, Where is the lead? Is it burnt off, or does the cu-pale or whatever absorb it? Never mind you explain the process later in the video. Thanks! But the Gold must oxidize at a lower rate than LEAD does, is this the difference between the metals? GOLD oxide rate = LEAD oxide rate?
Gold does not oxidize, my friend. This is why it is so important for industry and for jewelry.
Great mesh comparison. I'd never seen that before.
"now with the price of gold going up..." one person can make a nice tidy profit where a large corporation can not, this is a plain fact.
large corporations already made a tidy remittance so it all adds up..with the bonuses and
write offs...lol? I'd love to be able to get a bank loan and git me some 'o dem finely crafted
mo-chines. happy st.paddy day ! find some green gold !
thank you so much!!
please can you explain us what really the borax flux do to the materials !! aso the silicon ! and when we should use imestone and coke ? and more informations about lead peas and steel bar that you are soaking in the melting materials
with details please i hope that you read my comment

Sounds like you learned the hard way ,kudos for sharing
These videos are fantastic!
Next steps on your channel @Vo-gus?
Jason,you are so informative!! We learn so much from your videos!sorry about the crucible!😊
and here i thought the tailing pile was where all the rocks are for lapidary work! i never dreamed there would still e those kinds of values left
Very nice explanation so us laypeople can understand
So basically you have re-created the processes of nature in an off-grid factory.
Sounds trivial … NOT! Hats off to you young man. We need fewer PC nerds and more of you
What more can u say my brother.. it makes all cents.. keep up the good work my friend xox
Me and my friend decided it was a good idea to become gold gatherers. Got a kiln from a gold prospectors store. It was tiny and required two small torches. Melted some cons with it and it boiled over and made huge holes in the new kiln. Ran a second batch but this time the cup had a hole burned through it and when I lifted it out for the die the molten lava went everywhere and also ruined the kiln. To make a long story short we gave up.
As always ... very useful info Gold to Ya !
Mate that was an education! Awesome video many thanks!
VERY GOOD.. THANKS FOR SHARING
My exact area has nothing interesting. Nothing but coastal plains sediments of quartz and bog iron. You can dig a well down 300 feet before you hit any rock at all! Have to go 30 mins north or west to start finding some rocks, then mountains in north Jersey or PA.
