    Got out today around the LSD area, and waved to Bill as we passed each other . The thunderstorms almost bullied me out of this spot , but I stuck it out. Glad I hung around, as I found a very fine piece of wire gold...Enjoy !

    I found a nugget in a spot showed to me by someone I look up to. Long story short the agreement was to name the first nugget after him IF i found one. So i am introducing "Golden Tom Jr. Jr." .16 grams Found with sdc2300 Setting Sensitivity = 4

    Was able to get out on Fri. with Dave and Jen to do some exploring and detecting up in the San Domingo area. 5 Min. into the hunt I found a little guy. After that LOTS of trash But that is a good thing! Place has not been hit. Which seems unbelievable considering how easy it is to get to and the area around it I know has been hit. It was only down a couple of inches and the 9x14 got it. Saw some old mines, the palo verde trees are starting to bloom. Should look nice in a week or so. Took a pic of a tarantula hawk wasp. Nasty little creature if you read up on it. Found an intact box mold bottle! And.....broke another Idler arm on the YOTO. Did find out guys are making a brace to stop this from happening. I will be making one also as this is the 3rd one ive snapped. Getting kind of old. I had a spare in the YOTO so we swapped it out. Great day out and the weather was decent. Got blessed with a little yellow! Been a while. Tom H.

    Pretty compact little engines, and not much wasted space inside the case either! The last few days have been productive! I checked the ring gap on my piston rings and had measurements from .011 to .018. I used a small file and adjusted each ring to .018" gap. A little larger gap is good on a modified engine, that is going to run hard... it's entire life. I installed all the rings and inserted the pistons into the cylinders. They are ready to be installed onto the engine. I also painted the valve covers and sprayed a light coat of flat black on the cylinder heads. I may have assembly pics tomorrow if all goes well.

    Finally go the video finished of comparing equinox 800 to the gold monster 1000 on in-situ targets in the field. This is my no mean the comprehensive review as im sure the settings on the equinox could be tweaked more produce even better results. But from what i saw on my ground they were vary evenly matched. The gold monster seemed to pop a little harder on the targets, but the equinox still hit all the targets the gm1000 hit. Since i detect mainly creeks the equinox has a leg up since its water proof and i dont have to worry about it getting wet or falling in the creek. Hope you guys enjoy the video and ill take more footage as i work this little patch.

    https://www.msn.com/en-sg/news/world/man-stumbles-upon-nugget-of-gold-while-walking-dog/ar-AABjno3?li=BBr8YXK An Australian family has uncovered a small fortune while on a Mother's Day walk. The father, who wished to remain anonymous, said he was walking around the outskirts of Bendigo, in Victoria with his two daughters and his dog, aptly named Lucky. "Mum actually stayed at home so me, my two daughters and Lucky were just walking along," the man told The Age. "I actually walked right past it but my daughter pretty much kicked it as she was walking. She then goes 'Dad, is this gold?'"....... Weighing in at 624 grams, the family has been told their lucky find could be worth more than NZ$37,000 (AUS$35,000)....

    Dude I wish you would of posted your question about the new 151s before you purchased.. Or you may have and I just missed it. As a highly experienced drywasher with many pounds of gold recovered with the the gray box 151 ( model before 151s) it was a incredibly reliable and high recovery machine with an average of 90% recovery. I currently own three 151 boxes due to there higher recovery over all other drywashers. Keene was making them right as all 3 machines are about the same when it comes to recovery. It should also be mentioned I do not pre classify ever as it's a huge waist of time, there is a screen on a drywasher for a reason. Now when the 151s came out I was able to use one in the field... The biggest problem for me was the new 151s was loosing high amounts of gold to my tailings as well as the tray not fitting and spilling all over the place. I tried every secret I knew to help recovery and was very disappointed in Keene trying to reinvent the wheel on something that was working so well. I feel like they made it all complex so people would think it was better and spend the extra $... that was not the case as it is junk in my professional opinion. It may be possible I just got a bad 151s box. But seeing how you have 5 trays with problems I'm leaning that 151s is a bust. Here's an option. Send your 5 crap trays back to them and have them send you 5 trays from the original design. And send 5 original design fans with adjustable weights. The 151s had a new fan and weight system in the one I used and I didn't care for it as I couldn't change the weight counter balance.

    CBD with out THC is legal in all US states now. The only place there's a potential problem is Canada. CBD oil is legal there but only from Canadian suppliers. Technically, the hemp must be grown in Canada, processed into oil in Canada and distributed by Canadians. A licensed Canadian importer/distributor can bring it in with the right license. I know one CBD US company that ignored or didn't research the law that has had big shipments seized at the border and confiscated...Big loss for them. Canada legalized it solely for the benefit of Canadian agriculture and marketers. OK by me because there's a huge US market growing every month. I'm really enjoying helping others feel better and we had two major good results in our own family. My wife's step mom was diagnosed in Fall 2018 with stage 4 cancer throughout her body. Drs. started her on chemo immediately, and at the same time we began providing CBD oil to help her however it might. Six months later she's been given a clean bill of health, no cancer and she's been out of bed since February and doing well. One of Dodie's brothers has major diabetes and was diagnosed several months ago with major Macular Degeneration which apparently is a common effect of long term diabetes. He went back to his doctor very recently who told him there was no evidence of MD. The Doc was amazed, but we never put 2+2 together until we started researching it. Check it out! Cheers, Unc

    Jim was a good friend and mentor to many of us, especially those of us who got involved in nuggetshooting in the pre-1990 era. In the late 1980's he would frequently visit us at the editorial offices of "Treasure" Magazine, where many happy hours were spent "talking gold.". He was rarely absent from GPAA Gold Shows in Southern California, Las Vegas, or Phoenix/Mesa. At one such Show he approached my booth, handed me a spectacular specimen of auriferous quartz, and asked me "Where do you think this was found in Southern California?. Studying it, I answered "[site A]". "Nope." "[site B?]." "Nope." "[site c?]" "Nope." I then asked, as he turning away "So where?" "Ain't tellin'" was his response. Then he added, "but I now know of 3 new places to try!" ,

    Jeff, I sure appreciate you dropping in to leave such a generous and kind note, much appreciated, and I guess I'm one of the lucky ones as I have a spouse that's truly loving to chase the gold as much as I do. When I first started out chasing the gold, she wasn't that interested, but when I was dredging, she and my mother-in-law would pan my dredge concentrates. That was an eye-opener for her! (The mother-in-law got the nickname "gold grabber" as she'd always grab the nuggets and drop them in her jar!) After the dredge-concentrates fun, my wife really got into panning as well as sniping bedrock, and for the last few years, she's been my speed-panning expert (we throw nugget signals in plastic gold pans while we're detecting virgin bedrock exposed by placer mining [50-60 feet of overburden removed to access the ancient channels], as it saves us the time of ID'ing each individual target, and she pans out the nuggets!) Well, that also got her hooked on nuggets, and she's tried swinging the detector a few times over that virgin bedrock, and she's found a few too. (She hates the heavy Minelabs, loves the light VLF's) Because she's got the fever now, that's why she wanted her own detector, and she wanted a light one that would be easy to swing, and a detector that had an easy learning curve, but one with modern electronics that would do the job by handling the ground better than the older VLF's. So, that's why she chose the Minelab Gold Monster, and she had success the first time out!! I told her there's people out there that have had detectors for years, and they still haven't got their coils over gold, lots of trash recovered, but no gold, and she gets two chunks of gold the first outing, remarkable. All the best, and thanks for being so kind as to leave some feedback, Lanny

    Bob mentioned diatomaceous earth (DE). I’d like to point out that there are two types. There is the type Bob was talking about, which can be used to kill insects, is often used as a feed additive for livestock, and is totally safe for just about anything you can think of. Then there is the type used for pool filters. DE for pool filters has undergone heating to very high temperatures which changes its structure. This type of DE is an inhalation hazard and does cause silicosis.

    Gold Monster OutingWent to the gold camp in the Rocky Mountains last week. The weather was gorgeous, all kinds of songbirds back, plus the flowers of the mountain meadows are in full bloom, purple crocus and shooting stars, yellow buttercups, multi-coloured Johnny Jump-ups, etc., etc.At the camp as I was checking over the living quarters (camper and two travel trailers), a humming bird buzzed straight past my right ear! That snappy racket from those wings going a million miles an hour is unmistakable. So, we set out the humming bird feeders hoping to catch a glimpse of the beautiful and dazzling red to orange coloured throat of the Roufus variety before they head farther north, and we’ll keep an eye out for the beautiful iridescent green of the more common ones that sticks around all season.My wife unpacked her shiny new Minelab Gold Monster, and for those of you familiar with the machine, there’s not much reading to do, but I watched a whack of user videos before we hit the mountains so I could give my little darlin’ some tips and guidelines as she set out to learn how to use it.I picked a spot for her to try her luck on, an old fairly level place in a valley where some placer miners once had their wash-plant. The claim is now abandoned, last worked by some modern-day Chinese miners, but they left the area under a gloomy cloud, and I doubt they’ll ever be back.I gave my June Bride some general instructions on how to run the Gold Monster (I’d never used one before, but the YouTube and other user-posted videos were a great help. Furthermore, I’d like to give a shout-out to Bill Southern for his wonderful educational efforts.). But, we figured the Monster out quite quickly, and that’s why I’m grateful to Steve Herschbach for recommending I get my sweetheart one due to its ease of use, and kudos to Steve and Jonathan Porter for their write-ups on the machine which helped me quickly get a handle on the basics; their input was invaluable.By eye-balling the old site, I could tell pretty close to where the Chinese had pulled out their wash-plant, so I used that information to gauge where I’d have my wife start to detect as there are always some “spill” areas that offer a better shot at finding a nugget or two. Having said that, it was easy to see they had bladed and bucketed the area carefully after they were done to gather any spilled material; those miners were no greenhorns.I blocked off in a rough rectangle an area I thought might pay, and right away, my wife was hitting targets, but they were almost all ferrous, so she kept experimenting toggling back and forth between discriminate and all iron, learning the different sounds, learning how to make it easier to ID targets (to get them to sound off louder), learning how to read the little bar graph when it gave its indication of non-ferrous more than ferrous, as well as getting used to the sounds of shallow vs. deeper targets, and learning how to use the magnet wand to save time while sorting trash signals. (To elaborate, she’s a great panner, but a green, green rookie when it comes to nugget shooting.)The thing about detecting an old wash-plant set-up is that it gets very easy to quickly tell where the repairs (welds, patches, etc.) took place, and the numerous bits of welding rod sure make for some interesting sounds, and curious readings on the graph! Having said that, the Monster’s discriminator sure came in handy, and yes, depth was lost, but by using the small round coil, target separation was much better, and I was impressed at how my wife was able to move slowly from target to target, separating their locations, as she dug out signals.While she was test-driving the Monster, I was going for a comfortable cruise with my Gold Bug Pro. That is one hot machine, at least mine is. (I’ve heard detecting folklore that some machines leave the factory “hotter” than others, and I have no idea it that’s true or not, but the one I have is a firecracker for sure, super sensitive, and a true gold hound for sniffing out gold from tiny flakes to meaty nuggets.)I started to hit non-ferrous targets in one slice of her search area, so I marked a few so she could check them out. Well, those miners had liked their cigarettes, and there were plenty of crumpled bits of foil from the wrappers as well as some other kind of lead foil with a gold-coloured outer covering that made for some increased heartbeat, but only turned out to be a bust.After having dug some of those duds, she called me over. “Hey, what do you think of this signal?”. She was getting a great reading on the Monster, and it sounded sweet too. She worked the ground for a bit chasing the target around with her scoop (when a target runs from the scoop, it’s usually something heavy, as most ferrous trash seems to hop quickly into the scoop). Dropping the dirt from the scoop onto the coil, she moved things around and there sat a pretty little picker, about a quarter of a gram! Man, was she pumped!!So, she kept on working that rectangle while I ranged farther afield with the Bug Pro, and I too found all kinds of cigarette foil, and that maddening, thick lead foil with gold coloring--craziest stuff I’ve ever seen, and I have no idea what it originally contained. I recovered a small aluminum parts tag, several electrical connectors, bits of lead, and pieces of broken brass likely from a bushing of some kind.My wife gave another shout, and over I went. Her meter was pinning consistently in the sweet zone, the signal sound nice and crisp. Capturing the target, she threw the dirt in a gold pan. Next, she then used the Garret Carrot to chase the signal around the pan. She moved some dirt then cried out, “Look at this. Is this gold?” At first, it was hard to tell what it was due to a covering of grey clay, but using a bit of water soon revealed a sassy nugget! If I’d thought she was excited about her first find, it was nothing compared to her reaction on that one!I can only come to this conclusion: The Minelab Gold Monster is a sweet machine that sure produces sweet results, because it’s so easy to use, and it makes my sweetheart happy (couldn’t resist punning on sweet, forgive me).All the best,Lanny

    In case someone is interested in the real use of silicon dioxide in foods. From Wikipedia... Food and pharmaceutical applications[edit] Silica is a common additive in food production, where it is used primarily as a flow agent in powdered foods, or to adsorb water in hygroscopic applications. It is used as an anti-caking agent in powdered foods such as spices and non-dairy coffee creamer. It is the primary component of diatomaceous earth. Colloidal silica is also used as a wine, beer, and juice fining agent.[19] It has the E number reference E551. In pharmaceutical products, silica aids powder flow when tablets are formed.[citation needed] Also, just in case you would like to know.... Crystalline silica (quartz) is toxic and causes silicosis on the lungs. It is rarely used in finely powdered form. Food grade silica comes from huge sedimentary deposits of diatomaceous earth which is formed from amorphous silica (opal) and not crystalline silica (quartz). Diatomaceous earth has a very low percentage of crystalline silica and can be handled safely where ground quartz is extremely hazardous to handle. Please go up to my first post in this thread and read my explanation to Rylan about microcrystalline silica and cryptocrystalline silica and how to tell quartz from agate, opal, etc. This ties into this new discussion perfectly. It is exactly why crushed quartz is an inhalation hazard and diatomite is much less toxic. It is the difference between slow cooling under pressure (quartz) and rapid cooling at the surface (opal, glass, obsidian). It is how you tell if a rock was formed deep or at the surface. This discussion is supposed to be about basic mineral ID. We got there via a twisted path but we must come back to reality somehow. At some point we must try to exorcise the ignorance that clouds these discussions and make something positive out of it. Hopefully with this basic information a reader can actually learn something about mining, rocks and minerals rather than be misled.

    Don and Madge sold a whole lot of quartz from their hardrock gold mine back in the 60's to a bakery. It made the bread heavier and worth more. Because we all know how valuable heavy bread is. Because bread back on the farm was much lighter and worth less. It had no quartz in it. Back in the old days bread was not "stone ground" like it is today. Don and Madge sold so much silicon dioxide from their hardrock gold mine to bakeries that the profits from quartz were more than that of gold. You will notice that all food supplements that contain silicon dioxide are advertised as "stone ground". That means it contains quartz to make it heavier and thereby more valuable. Heavy food and diet pills are worth much more than light bread and diet pills. This makes barren quartz a valuable commodity worth mining. That is why so many famous mines have names like "The Pumpernickel" and "The Marble Rye". …….. Why cant we all just pretend that this is factual information like we do with our elected officials? Just go along with it. Don't rock the boat. Be polite and swallow the "stone ground" BS and smile. Wave a flag or something. Remember, kids use this forum for learning about stuff. So meteorites cause fires, maritime laws don't apply to natives on natïve soil and bread has ground quartz in it. Wear a wool coat in the summer to keep cool and have your letters in red ink signed by the postmaster. Drink some vinegar shots and smear coconut oil on your temples. Because this is the wisdom of the ages that experienced men have to offer the children.

    Hi guys, I was in Bendigo that day and have been in the area for over a week now. They allow people to hunt for gold in their parks. Bendigo is a pretty big city and it is like having LSD as part of the greater city. They don't turn their parks into Monuments, National Recreation areas or State Parks which make them off limits to detecting. There is a follow up to that story. When you are in Australia prospecting in the parks or the forests (there is a difference) you need what is called a Miner's Right to keep the gold you find. There is some 'question' if you need to be looking for it or just take it if you weren't looking. The story now goes that they little girl who found the nugget and her dad did not have a Miner's Right (license) which only costs $20 for 10 years. It is unknown what is going to happen to them or the nugget based upon the law. On another story, about the same day up in Wedderburn which is northwest of Bendigo some was walking and found a 7.5 oz nugget. They didn't take it to the papers and they don't have the problem with a Miner's Right! I have a Miner's Right but I only have a couple of little nuggets which total to about 1g. I wish I had their problems! Mitchel

    Hello. My name is Garik i will be age 45 on June 7th and i live in Queen Creek. I was born in Phoenix but grew up in Mesa. My main hobby has been building computers since i was age 15. I think its time to add a new hobby, gold metal detecting. I finally saved enough money to buy a metal detector. I always wanted to do it since I've always been fascinated with the Lost Dutchman Mine. For the past month I've studied a lot of information about superstition mountains and gold metal detecting here in AZ. From what I've learned i'm assuming the best places for me to go are Wickenburg and Prescott areas. Black Canyon i hear has some good spots as well. I will also be joining the Roadrunners, from my perspective this would be a wise decision. Last week I actually bought a Metal Detector, the Garrett AT Gold. I returned it unused a few days later after having a feeling i could probably do better with a Minelab Gold Monster 1000. I'm still debating on what brand to purchase. I'd like to thank "Mr. Nugget Shooter", your videos taught me a lot thank you.

    Drilling rock, blasting, cutting and grinding concrete, cutting stone, even rock tumbler dust. Silica is a huge respiratory hazard and can cause all sorts of problems from long term exposure. But your stomach lining is pretty tough and does not scar up like your lung tissue. I don't think it would cause you any problem at all in your gut but I really don't know. I will probably just make you fart. Silicosis was called "Miners Lung" back in the days of hand drilling. The guy turning the drill would wrap the steel in a wet burlap sack to keep the dust and chips out of his face. Drillers lungs would still give out in just a few years due to the fine quartz dust that was always being generated by the steel impacting the rock. Modern mining drills use water and air flowing through the center to keep the dust wetted and eliminate the inhalation hazard. But activities that grind, drill or smash rock dry are as hazardous as heck. Guys who sandblast and work around rock crushers must be super diligent about keeping that respirator on their face. Even flint knappers can be exposed to high levels of silica in the air for long periods.

    You can mix diatomaceous earth and ground tobacco dust at a 1:1 ratio and it makes the best insect dust you have ever seen. When it is dry the DE is lethal to most insects but when damp it does nothing. That is when the tobacco starts destroying bugs. Neither will harm plants at all. Wicked good organic insect control. It is especially good for fungus gnats in the house that come from the potted plants. A good sprinkling of the mixture on the surface of the soil keeps them in check. They use it when making and storing acetylene. It allows the gas to be pressurized without ignition. And it is used in much the same way in dynamite to stabilize the nitroglycerine. Awesome stuff that diatomaceous earth! ….But will it make a more valuable muffin?

    I use fumed silica to thicken epoxy resin. I think that is exactly how it is made. They heat up DE and re-crystallize it in a flue. It is like snowflakes.

    Obsidian, Saffordites are a lovely lavender colored natural glass stone found only in one place on Earth. Often called Saffordite tektites or sometimes referred to as Arizona Tektites, they are really members of the obsidian glass family of rocks. Saffordite stones are mysterious in many ways. For example, Saffordite hunting has been enjoyed by many people for years and yet the source where Saffordites originate has never been found. They may have been moved by water many miles during the ages they have been in the ground.Saffordites usually have a round or oval shape which supports the idea that they have been tumbled and shaped by agitation in flowing water. The surface of Saffordites is usually pitted with cup-shaped depressions similar to the ones found in tektites. Some Saffordites are gemmy clear and sparkling when held to a light. Other Saffordites are banded or translucent instead of clear. Some are opaque but each type of Saffordite will appear very black when seen without light from behind. When they are viewed with a light from behind they truly show off their inner beauty. The banded Saffordites are often especially interesting when backlit. Cheers! billpeters

    I agree that the color you are seeing is light refractions from tiny cracks in the stone. It looks like quartz and not opal. They are made of (virtually) the same stuff but quartz is crystalline and opal is amorphous. You can see the granular structure in your stone... like crystallized sugar. Opal is not crystalline at all. It is just like poured glass. And the vast majority of opal has no color or flash at all. That is "precious opal" and not "common opal" which is quite common in volcanic geology. Learn the subtle differences between "microcrystalline" and "cryptocrystalline" stones and you can spot the difference between quartz and other minerals (opal, agate, jasper, etc.) pretty quickly. Up where you are the minerals associated with recent volcanism are going to be scarce. If you find any they are going to have been transported a long distance and be the most durable stones to have survived the journey. I would opine that opals and such would not be on the menu at all. They are soft, crumble easily and do not survive transportation well. Agate and jasper nodules on the other hand are tough and nearly indestructible. They can travel thousands of miles unaltered. So can quartz. See how that specimen is cloudy kinda like a sugar cube? How it breaks in little chunks rather than in little conchoidal flakes? That is the subtle difference between fracture and cleavage and one of the main determining factors between crystalline (quartz) and amorphous (opal) silica minerals. The larger the silica crystals the more pressure the specimen as formed under. Some quartz has large crystals and was formed under great pressure. Silica like agates, jaspers and opals were formed under low pressure (near or at the surface) and have very tiny crystals. Hit a few specimens with a hammer and you will quickly see the difference between the quartz which will crumble along cleavage lines between the crystals and agate (jasper, chert, opal, etc.) which will break conchoidally as the stress wave flows through the amorphous (non crystallized) material.

    Silica is extremely deadly when taken into the lungs in heavy quantities. Causes silicosis which closes/plugs off the air sacks in your lungs. Obviously its not an over night thing but long term. In the mining world, we have to be fit tested properly and wear a respirator anytime we are around the crusher/mill areas that produce even the smallest quantities of dust. As far as the digestive tract, i wouldn't see it being super bad. Now maybe if it were a heavy metal it might be an issue. Silica is very sharp, so maybe a bunch of it might actually collect in you and cause damage but im not sure.
