Metal Detecting
I am a Lower 48 newbie but off to a good start thanks to guidance from Chris Ralph, proving again that who you know is often more important than what you know when it comes to finding gold. Chris took me to a few places he was interested in. We had a great few days with some varied experiences, topped off with me finding this nice 0.82 ounce gold in quartz specimen. It was found in the northern Sierras of California with a Minelab GPX 5000 metal detector sporting a Nugget Finder 14" Advantage elliptical mono coil. There is a lot of gold showing so probably well over a half ounce of contained gold. The nugget was caked with mud and cemented material when found so was a bit of a surprise when it cleaned up so nice. Thanks Chris! image.webp

Another handsome piece Steve... it's good to see your early successes in new locations... says a lot about the individual behind the machine. Congratulations. :icon_thumright:

Jim.
 

Thanks Jim. I hope your summer of prospecting went as well as mine because mine has gone very well indeed!
 

Ha! Ha! So it would seem that detecting in the goldfields of the Southwest suits you right down to the ground Steve!!! No surprise there and the best part is that you ought to be able to hunt year-round.

My autumn prospecting turned out well… less silver than usual, but all good quality. Most of the best finds were made during the last week… this is getting to be a habit for me. A lot of small silver at one to fifteen oz range totaling maybe twenty lbs… haven’t weighed it yet, largest piece slightly over ten lbs, and a half-dozen keepers between two and five-and-a-half lbs.

The five-and-a-half lb chunk was my favorite find. I’d spent the entire day digging “good” Infinium hi-low signals to find all manner of trash… particularly flattened iron, some quite deep. Some might suggest a VLF was called for in such trashy environs, but I persisted with Infinium because of the diabase background, and just plain like using that unit for silver. With dusk approaching fast, the coil swept a wide, loud… obviously shallow… signal that couldn’t possibly have been overlooked by others… so it had to be iron. Digging away expecting iron trash any minute Steve… I rechecked the hole (with the 8” loop attached… all I could handle as I damaged my shoulder) and there was no signal. Whipping out my Propointer I swept it across the diggings and it sang out with a steady hum over a good-size, dirty rock. I briskly rubbed the surfaces with my leather glove, took a look… and was astonished. I held in my hand what was undoubtedly as rich and pure a moderately large native silver specimen as I’ve ever seen… a real tripmaker!! Just enough calcite to accent the massive silver… perfect!!

Some hunters become frustrated with digging endless iron trash but no silver… and leave such sites for supposed “better pickings” elsewhere. I hold that trashy sites are a good thing… otherwise the detectable silver would soon all be gone. It took many years of experience to learn persistence and build confidence that the silver is there… all you have got to do is use some imagination and elbow grease to find it. So I’ve learned to take the iron trash philosophically as all part of the day’s work… and never even consider becoming discouraged by it. What silver isn’t found today will be found another day.

Additionally… I finally managed to find a large, two-inch-thick heavy red erythrite encrusted-on-cobalt vein with scattered native silver throughout… attached to pink granite… slightly under 42 lbs. This is something I’ve wanted for many long years… definitely museum quality. Plus I finally got a good crystalline specimen of arsenopyrite without any silver, cobalt, or nickel mixed into the matrix… my brother let me have it. No photos available yet, hoping to clean some samples out in the patio over the next few weeks if the weather will cooperate… maybe do a quick non-technical write-up to post here sometime in the new year.

The weather was mostly warm and sunny right up to the last week… when it turned miserably wet and cold. Had blazing campfires every night... went through two cords of firewood this autumn, plenty of visitors, and altogether had a memorable time. Even got out with “cryptic” here on the forum… and found some nice examples of very large crystalline garnet and many other interesting minerals.

I look forward to and enjoy every aspect of prospecting more than words can say… there is no doubt in my mind that we share that sentiment fully. All the very best moving forward...

Wow, Jim, sounds like you also have done quite well this summer. Good for you! Silver hunting sounds very fun and rewarding. Funny but the way you are hunting matches how I hunt tailing piles for gold. If I think there is gold, I just dig everything. I have seen too many nuggets called iron by discrimination systems. As long as time allows there really is nothing for it but to dig every target. As long as something goes beep, there is always hope.
 

Hey Steve,
I sure get jealous to see you guys hitting the good stuff. I'd love to get some silver nuggets as well.
I've been told by other detectors to dig everything and not go by the ID number. I pretty much do dig everything. I figure I'm helping clean up the desert a bit. Got 2 5 gallon buckets of iron and brass. Waiting for year end to see how much I've earned. Lol.
Hoping to go up north to dig some more and hopefully do some detecting. I'm debating on getting the sniper coil for my ATG. Especially since where I go there's more pickers than nuggets. I'm curious if you've got an idea of how small it could pick up. Heard a size 8 buckshot. I know my coil hasn't picked up that small but I've got some small wire about a 1/4" in length. So I didn't think it'd have a problem picking up the small pickers. I was wrong. Lol.
I was running my coil over a small piece of gold shaving. Pretty much the size of the biggest picker I get in highbanker. I had sensitivity up all the way and had it so the buzzing sound was constant. So I swung over it and the buzzing had a pause (no tone though) and then buzzed again. I'm wondering why the empty spot when going over the gold.
I was thinking, I hear this all the time when hitting the washes, am I leaving gold behind that my detectors hitting but not giving me an ID or even a tone because it's so small?

Wow Jim. What a year you've had. Wish my kids would have that enthusiasm. Dig it all up. Now I've got to just get out in the fields more. Been digging holes and running dirt through my highbanker. Hoping in the next couple weeks I can detect after getting my quota of dirt. Lol.
When you find raw silver, is it a dark gray? Just wondering because I'd hate to mistake it as lead. I've been looking at pics of silver in old mines and it looks like iron almost, but it's gray. Not shiny of course.
 

Well, I use discrimination when I am tired or time is short. I promise you though if a spot produces gold eventually people will detect that spot until nothing goes beep. Known locations get pounded until nothing is left so I try to just cut to the chase and get it done myself.

The little 4.5" hockey puck on the AT Gold is good for tight locations like down in pockets in bedrock. It is a hair better on small gold than the 5" x 8" DD. I honestly cannot recommend it though unless you are already finding quite a bit of gold with the stock setup. If you are not, investing more money in coils is not the answer. Put more effort into putting yourself on better ground. That is the name of the game.

I see that a lot of that in the prospecting world. No results being read as a need for more or different equipment. Once you have faith in yourself and your gear the real answer is move on to another location.

GarretDiggingAz… I think for those of us not familiar with naturally occurring native silver it might be easy to confuse it with manmade lead, particularly melted lead or what-have-you. We occasionally come across melted scrap lead in mining country much of which has the shape and character of a worn silver nugget, and both have similar specific gravity, but it just doesn’t have the metallic look and luster of natural native silver. Both occupy similar target ID range on a metal detector so this isn’t a useful tool to distinguish the two metals.

Buried lead normally develops a pretty good beige colored surface coating due to lead oxide formation, whereas the surface of naturally occurring native silver is usually darkened to some extent by tarnish. As you said, anywhere from shades of grey to black due to silver sulfide formation is most commonly found here.

Try a quick streak test, and do it outdoors, by running it across a piece of unglazed porcelain. Unfinished bottoms of white coffee mugs will work fine for this test. Silver yields a bright silvery metallic streak whereas lead will produce a grayer streak… and normally a “thicker” streak line because it is softer. As you do this, you’ll “feel” the difference in hardness between silver and lead. Lead is obviously softer and grayer than native silver. And incidentally lead melts slightly above 600F whereas high purity native silver requires temps approaching 1800F to melt.

Briskly rub native silver and a lead piece with a leather glove. You’ll notice that the “rubbed” area on the silver will remain silvery bright with a high metallic luster that will last many years. Lead will also initially produce a silvery look that isn’t quite the same. It is duller and lead will “hold onto” your leather glove more as it is rubbed. It feels almost slightly sticky or greasy / grimy. After a few days or even an hour or two the lead starts to go filmy gray and loses its luster.

Honestly, lead isn’t really something I think about much. I can see the difference and a brisk rub with a leather-gloved hand ought to dispel any confusion. You should also research if native silver occurs in the area you search.

Silver hunting sounds very fun and rewarding... the way you are hunting matches how I hunt tailing piles for gold. If I think there is gold, I just dig everything. I have seen too many nuggets called iron by discrimination systems. As long as time allows there really is nothing for it but to dig every target. As long as something goes beep, there is always hope.

For sure Steve… there is nothing like autumn prospecting for silver in the boreal forests up on the Precambrian Shield. The brisk northern air, the allure of leafy forest scents and vivid colors while hiking through the woods, the infinite fascination of seeing the first gleam of freshly dug silver, grading such ores by the light of blazing campfires… this is really living and by a wide margin. I enjoy searching for rocks that go beep, and just can’t imagine life without electronic prospecting each autumn. I hope to drop dead one day… years from now of course… up there on the Shield.

I agree with your detecting remarks. I prefer my PI units, especially Infinium for this application. I don’t use VLF discrimination for general searching and don’t pay much attention to target ID unless right on top of a strong signal. So there’s a lot of digging either way. But I get better depth than VLFs as magnetic soil mineral strength increases, and larger coils improve that depth compared to same size coils on a VLF unit even in modest soils. Plus the deep elongated iron is mostly identified with Infinium's low-hi signals in zero and reverse discrimination and that is a capability that saves a lot of digging. And its something that VLFs struggle with… particularly drill rods at depth.

On the other hand VLF target ID and discrimination have no value at all if the unit can’t detect the deeper silver in hammered areas. A very strong case can be made for using PI units as primary tools in this application.

The ATX looks interesting so far. I'm happy with Infinium for what I'm doing, but think I'll have get a close look at ATX by next summer.

Great looking specimen, Steve! I really enjoy seeing your posts.

Jim- It was fun to get out with you again this year even if it was for only a short time. Glad to hear that you managed to find some nice silver specimens!

Thanks Cryptic... I can't remember ever spending such a pleasant autumn afternoon as with you and your son Kyle. He's a great kid, and so refreshing to spend some time with such a well-behaved little guy. Mine are all grown-ups now and I miss those times. I thought at the time we might find a chance to use these photos and sure enough here they are below. That crystalline garnet was the largest piece found, but many other individual large garnets were recovered too. Some quite red... what a bananza... thanks again Cryptic for a great outing.
