Do you love to chase the gold? Please join me--lots of gold hunting tips, stories of finds (successful and not), and prospecting poetry.

Nugget in the bedrock tip:

I had a visit with a mining buddy this past weekend, and he told me of an epic battle to get a nugget out of the bedrock, and of what he learned from the experience. I thought some of you might like to learn from his mistake.

While out detecting one day, he came across a large sheet of bare bedrock. The bedrock was exposed because the area had been blasted off with a water cannon (a monitor), by the old-timers! It was not fractured bedrock, in fact it was totally smooth.

He was not optimistic at all of the prospects of a nugget. But, for some reason (we've all been there) he decided to swing his detector over that bedrock. After a long time, just as he was about to give up on his crazy hunch, he got a signal, right out of that smooth bedrock.

There was no crevice, no sign of a crevice, nada! So, he had to go all the way back to camp to get a small sledge and a chisel. The signal in the rock intrigued him, but he still wasn't overly optimistic. For those of you that have chased signals in a similar situation, sometimes there's a patch of hot mineralization in the bedrock that sounds off, but this spot, according to him, was sharp and clear right in the middle of the signal, not just a general increase of the threshold like you get when you pass over a hot spot in the bedrock.

Anyway, he made it back to the spot and started to chisel his way into the bedrock. If any of you have tried this, it's an awful job, and you usually wind up with cut knuckles--at the least! Regardless, he kept fighting his way down, busting out chunks of bedrock. He kept checking the hole, and the signal remained very strong.

This only puzzled him all the more as he could clearly see that it was solid bedrock with no sign of any crevice. He finally quit at the end of the day, at a depth of about a foot, but still, nothing in the hole.

An experienced nugget shooting friend dropped by the next morning to see him, and asked him how the hunt was going. My buddy related his tale of the mysterious hole in the bedrock, and told the friend to go over and check it out, and see if he could solve the riddle.

Later in the day, the other nugget hunter returned. In his hand was a fine, fat, sassy nugget. It weighed in at about an ounce and a quarter! After my friend returned his eyeballs to their sockets and zapped his heart to start it again, he asked where the nugget had come from.

Imagine his surprise when he heard it came from the mystery hole!! He asked how deep the other guy had gone into the bedrock to get it. "Well, no deeper" was his reply.

So, here's the rest of the story as to what happened. When the successful nugget hunter got to the bedrock, he scanned the surface got the same strong signal as my buddy. He widened out the hole and scanned again. Still a solid tone. He widened the hole some more so he could get his coil in, and here's the key and the lesson in this story, he got a strong signal off the side of the hole, about six inches down, but set back another inch into the side of the bedrock!!

My unlucky friend, the true discoverer of the gorgeous nugget's resting place had gone deep past the signal while digging his hole!!

Now, of course, a good pinpointer would easily solve this problem. The problem was, my buddy didn't have one, so why would he widen the hole, right? Well, the other guy was the one with more experience, and that's why he did. It was a lot more work, but what a payoff!

So, my buddy's butt is still black and blue from where he kicked himself for the next week or so for having lost such an incredible prize.

Some nugget hunting lessons are harder than others to learn. . . .

All the best,

Lanny


P.S. When in gold country--check the bedrock, regardless of whether it looks likely or not! Mother Nature likes to play games sometimes.

bcfromfl (FL??? Been there done that...the fact you are missing the gold fields here means you get it.. but just like they used to say...it ain't easy.) My goal for 2016 was to re-read this thread as I am certain I would pick up more since my first read in 2014. Life objected so I wait to employ what Lanny has preached to me so far but I can tell you his methods (in spite of my rookie status) has paid off. I will get out soon too...my site is found, there and waiting for me to prove myself. :thumbsup:

Jeff, so good to see you back with a few more comments. I appreciate that you've been able to pick up some tips that have helped you trap some gold, and the more you apply what you're learning, you'll soon get to better gold. It's like anything else, the more you practice the craft with the right knowledge and proper techniques, the better you'll do and know what to do to continue to get better.

All the best, and good luck this season,

Lanny
 

Hi Lanny
I picked up a GPZ in February and March has been quite warm. So I took it out for a run. There was only about a football field worth of open ground but the detecting was great. Can't wait for all the snow to go! Minelab has outdone themselves!
All the best!

Hi there,

Glad to see you've got yourself a GPZ, you'll have to drop in and do a bit of a write-up if you don't mind to tell me exactly what you like about it. I see the price has dropped, which is a good thing, and I'm all ears for specific feedback from you on what you enjoy about it, and what you still think could be improved on.

Congratulations on the beautiful finds, and having seen some of your truly beefy finds in the past, you're a nugget master of the first order.

Good luck up there this season, and may you find one the size of your shoe this time around!

All the best,

Lanny
 

Thank Lanny, I will keep you posted.....

Thanks! I really appreciate it. I love to look at new technology that might benefit my nugget shooting efforts. Nothing like getting a better shot at some sassy gold.

All the best,

Lanny
 

Just some thoughts:

The biggest mistake I see people make that rush out to buy a nugget hunting machine is they don't take the time to pay their "dirt dues"!

What are dirt dues? Well, one of your dirt dues is to read, reread, re-reread, then re-re-read, etc., etc., until you truly know the content of your detector's manual, and its capabilities and limitations.

Another dirt dues rule is to get that machine out as soon as possible and then get it finding things. It really doesn't matter initially what the metallic targets you're finding are, because it takes many hours to learn the tiny differences in your machine's capabilities; just get the machine out there and get digging targets, and targets at widely differing depths is important too. Then find some more targets, dig some more, and keep at that repetitive cycle as every find will teach you, your brain, and your ears a bit more about the metal detecting chess match you've signed up for.

More dirt dues are to spend hours and hours recovering targets in as many different soil types as you can get that coil over. Trust me, trust everyone else that's ever written about this if you can't trust me; the soil conditions are a critical aspect that significantly affects detecting; they do matter; it's something you must learn about, and learn well by listening how to pick up tiny, critical differences in sound in that hot ground.

This is a big, big dirt dues must: never, never give up until you've found that first nugget!! I'd dug buckets and buckets of trash before I got my first nugget (no exaggeration on this one), and since that first one, the nugget lottery has just kept on rolling. It seems that's the way it is.

Nugget dirt dues requirement: you need to understand how difficult it is to hunt nuggets. It's a ton of often boring, tedious, and hard work, but when you hit those gold nuggets, there's nothing else like it!

Another dirt dues requirement is to get a set of headphones you'll actually use, and spend the money to get a quality pair to boot. External speakers have their place, but a lot of nuggets would still be in the ground if headphones weren't in use.

The last one I'll post here is the research on locations, and the specific support training you require for your machine, or on proper techniques: watch youtube videos about your detector; watch others recover targets and learn their tricks; visit forums and websites, read books, and be sure to read stories of actual finds as one of the biggest dirt dues requirements is to become a giant sponge that absorbs every bit of material on nugget shooting that will give you any kind of edge whatsoever.

All the best, and I realize this is not a complete list, so feel free to add your "dirt dues" requirements,

Lanny

Nice one! Trusting the machine is an essential, and when a person is out hunting with the machine long enough, that's a great way to build the trust.

All the best,

Much discussion on getting inside of rocks, crevices etc .. here on this thread and importantly so (as I have been learning). Just wondering if anyone has used this stuff "Non-explosive demolition agents are available under a number of brands, Dexpan, Ecobust, Crackamite and Syletmite etc" Came upon this while searching of ways to demolish some old concrete steps on my lady's farm.

Man those look like some Solid Steps. Any idea of how they were constructed, like maybe with rebar or if they are hollow? Might scan the steps with the TDI to get an idea if any steel is inside the cement.

The non explosive stuff requires holes to be drilled in the subject rock (cement is basically rock, unless it has rebar in it), pour in mixed solution and go BBQ some food come back X amount of time later and the rock is broken up. What are you going to build to replace them? Different stairs, a deck, a ramp?????????????? I built a deck once and used the UGLY Cement stairs as part of the support for the deck, in that case no need to waste time taking the steps down. Best of luck with your project.......63bkpke

... thanks 63

Ended up with renting a turbo electric demolition hammer... worked great. I could not get that non-explosive powder anywhere but looks like it may have some prospecting applications if you can find a wide crack in a large boulder.

Bristar, Bustar, etc. as well.

Here's a youtube video of the non-explosive "expanding grout" in action. It does take multiple hours to work, and you need to do some serious drilling, but I can see some applications for mining. Glad you've already solved your problem.

In the video, I count six (?) drill holes when the bedrock comes off.



Here's another video by a different company:

Very cool stuff and I always wanted to give some a try. One nice thing is it is quiet. I have also heard that a patient fellow can achieve the same thing by drilling the holes and adding water to allow freeze/thaw when it is warm days and way below freezing at night. I also wonder if one had six holes in a line as in the video, if the same result could not have been achieved with a sledge hammer, as the rock has already been compromised?

Stealth blasting? What a covert idea.

It's amazing what sweat equity with a sledge hammer will accomplish . . .

Hello to all. Haven't been out yet this season, broken bone issue, but hope to get out before too long. Here's to all of you, and I hope you're finding some of that beautiful golden metal we all dream about.

All the best, and may the fever be with you,

Lanny
 

Sorry to hear that, Lanny -- hoping for a quick recovery! I've been thinking about you this season, and wondering what plans you might have in that amazing wilderness backyard of yours. You're such an active person, you must be about fit to be tied!
 

Hello Lanny,
As bcfromfl has offered, I add my thoughts of a quick and full recovery for you! It is difficult to be sitting on the side lines waiting for the coach to call one back into the game but then one must take their turn and return when the timing is right, recover completely and well!...................63bkpkr

Bummer...........Here's hoping for a speedy recovery for you...
 

Lanny - I wish you a speedy recovery. As laughter is the best medicine, I offer the following to help:

A man enters his doctor's office and explains:
"Check my leg, as there is some sort of problem. Please put your stethoscope against my thigh and listen."
The doctor did as he was told and heard: "I really need 50 dollars."
Next he put his ear to the fellows knee and heard: "I really need money, please give me $100 dollars".
Lastly, the doctor listened to the bone above the ankle and heard: "I could really use a loan for $200".
The doctor searched his medical books to no avail. So the pondered the problem and offered an explanation:
"Your leg appears to be broke in three places."
