  1. From too much geology study 25hrs a week.worth of GeoBabble. But Did Find a new spot to detect Today Without Snow.. Southfacing , near an area that I witnessed w crossbedding in sedimentary sandstone( all firsts for me! applying sedimentary petrology learned recently to the structure! i.e.roadcut of a maybe? To try and detect? what appeared to me to be an ancient streambed covered by ash.....Any Thoughts out there Experienced Operators care to share any thoughts be appreciated....that you are willing to about this exposure...Eye didnt have darn camera and phone was dead. when i spun around and parked the Cherokee,. the gravel looked out of reach??? it was prob. and average of 6ft below the top of the bench...ancient stream..pinched out sitting up there 45ft. straight up.. and 6-10 ft. below the scrub grass bench Surface....the 100yd exposed roadcut seam is 2meters thick baseball, softball,football, size cobbles w/some soccerball size boulders.down below a 4-6ft.ashy yellowish peach crumbly rhyolite I also assume....? those 2 layers are sittin ontop of the more "massive 40-50ft exposure of crossbedded sandstone!! It's Beautiful to Me and its color is Grey...was goin to try the .45 00 w/ the 20inch NF Round or the 14inch NF round? I havnt actually havnt swung any detector Ever" "yet" over a piece of 'Nativegold" I'm A Newbie only in the sense of never hada season or day " yet" of 8hrs inthe field or 24 or 72 straight... just plinking around while learning as much from the Forum as well as The Best Minelab Operator's and Geologists i could find! have theright gear and playing the Exploration Geo" wannabe First before I "breakdown in tears and have to be a Spot Guy" and Go to Rye Patch... to get Lucky...for my first piece.(no offense) but I'm more of a Pattern" Fisherman. And I'm Looking for Pounds Of Gold" Only place i can detect w/out snow for 100 miles...What Have I Got To Lose...Break myself in early.....where i wana go is 8 weeks to 4months before those areas open and the season begins for me....You Know "The Start"!

  2. We all talk about gold and fault lines BUT how do you go about finding these fault lines exactly? They are not shown on Topo maps that I know of. What maps should I be looking to acquire? What do they look like in person? Sharply uplifted rock areas I am guessing? -Tom
  3. Just Wondering if the Forum has any good wild plant stories? Care to share any Tips' of Real Nugget Digs associated w/ plants , flowers, trees.etc. I don't besides Horsetail(see pic) is supposed to grow in Gold" ground. "Geobotany" Starts Here: Vegetation as a Guide. Sometimes the vegetation on the two different rocks, especially when decidedly unlike in composition, is so different that the line of contact may be traced by it alone. In open countries free from heavy timber, like Arizona, this is strikingly the case. Probably the most distinctive vegetation in those localities is the various forms of "yucca," of which the "Spanish bayonet" is a sample; and the "ocotilla" (o-ko-te-ya). The yucca is confined to the granite or quartzite rocks, evidently liking a soil abounding in silica (quartz); the ocotilla is as decidedly confined to the clay-slate regions, the line of contact being often drawn on a hillside by these two plants as if defined by a fence; while the cactus frequents the limestone outcrops and the areas of eruptive rocks. In other words, for successful growth, the yuccas require quartz, the ocotilla clay, and the cactus lime. In the broad washes or beds of summer torrents, called "arroyos," where the rocks are mixed, all three may be found growing if the debris is of a suitable character. A fissure may also be defined by the vegetation growing on it being different in character, or a line of contact may be traced by the same means, as in California, where the rim rock of the gravel channels, even where covered and obscured by dense brush (chaparral) can be followed along the mountain side by the elderberry bushes, the white flowers of which are very conspicuous in the gray brush in spring. These bushes require permanent water and have located themselves along the bed rock rim where the water in the gravel flows over it or on the top of the pipe-clay just below the lava cap.

  4. Just curious as to whether a gold detector can detect through several inches of bedrock?
  5. Why does California have so much gold that is seemingly just laying not far below the surface of the topsoil?
  6. This isn't about gold and I know this is a gold oriented forum but there are a few geologists and miners with a lot of experience in many things so maybe someone can help... My question is, how exactly do you go about mining and seperating a material like vein jade without destroying it? Seems like with blasting you risk blasting the vein apart too. Even if I did blast and broke the diabase into manageable cobble sizes that I could remove and process, how would I remove the actual vein itself without destroying the jade? A little backstory, one of the minerals I'm prospecting for is jade and I've found some veins (nothing economic or gem quality yet) finally so I think I'm on track to finding something better and potentially worth mining. But it got me thinking - with ore mining you can just blast it apart since it's being crushed anyways. But with something like jade where the vein is in place in rock and you want to keep the gem material as intact as possible, what would be the best method for mining and extraction? I have finally located a few veins, they are low quality material not worth mining and far too slim anyways. But even if these veins were good material I'm not sure I see a good way to remove it. I tried chiseling with very little luck. The veins are in either basalt or diabase and the rock is very hard and durable and the jade doesn't want to seperate easily. Most jade mined or even just collected by hobbyists is float in alluvium it seems like, so I'm not finding much useful info online on how to approach this. I'm attaching a photo of a small vein I found as an example, it's only 1/2" wide and low quality olive jade so not worth mining, but this is still the same rock and material I'd need to mine and work. Also here is some gemmy good deep green material I just cut off a boulder I found. This is Wyoming nephrite, it was float but still had vein material attached so I think I'm getting close.
  7. First off, I'm talking about placer gold. Secondly, I realize this is a simple question with a very complicated answer. But in probability/statistics/percentage terms, I think it's not that crazy. Most, if not all gold is going to end up in the ocean if it's not recovered by one of us. But even once loose from it's origin that could take many 10's of millions of years. In the meantime, gravity is pulling it towards the earth's center. Even dense clay can stop it for a while, but usually it sinks until it reaches bedrock, and even then it can be horizontally displaced unless it falls in a crack/crevice. If you're using a metal detector there is a minimum size that can be detected. "Young gold" (that which has only reached its current location in the last days, months, or even few years) tends to be sub-threshold gold in terms of metal detecting (I think -- please correct me if I'm wrong). So if you're going to find placer gold with a metal detector it most likely has been at or near its current location for a long time, meaning on the order of tens or hundreds of thousand of years at a minimum. (Obviously there are exceptions, but I'm talking in general.) So, to cut to the chase, if I'm using a metal detector to find placer gold and I'm not getting to bedrock, am I just spinning my wheels? Postscript: I'm no expert on this. Maybe my assumptions and conclusions are completely bogus. If so, I welcome/encourage you to say so. I'm trying to learn, not protect my ego.
  8. Best gold hunting video I have seen of pocket gold hunting in NW USA. Always wondered what this serpentine/greenstone really looked like plus contact zones, how to read geology maps vs Natl Forest maps, etc.. http://www.goldpannersguide.com/#!bookstore/mvjm7 Looks like I will be buying some more gold books/videos for my library from this place...not much info around on Pocket gold hunting.. One of their online videos is from ICMJ and explains how the western states got to where they are today, mining wise, and why all the hassles vs 1872 and whats being done to try to resolve it.
  9. https://student.societyforscience.org/article/gold-can-grow-on-trees-pointing-rich-deposits-precious-metal-below-ground I was doing some research on Stunted trees as related to possible Plant indicators for gold and came across this website. Eucalyptus trees in Australia found 1 lucky geologist a big gold strike . I was told some trees I found that looked like they belonged in an evil enchanted forest could be indicating a rich mineral deposit close by? The same trees, just 150 feet upstream on this little gully are so stately by comparison, 100+ feet in height and maybe 2 foot thick trunks and thick leaf cover, whereas downstream the Evil trees have thick branches within 2-3 feet of the ground and might be 25 feet tall, short, fat, and UGLY. The gully starts out as black soft mud by the stately trees and is brush covered and dry by the stunted trees. The adjacent fields are gravel and there is a gravel quarry just north maybe 1/4 mile. And a large gravel bottom creek runs thru the area to the nearby river. I haven't been to the area in a long time cause there were hand size paw prints in the sand with 3 BIG toes and following a deer. I am assuming it was a cougar, not a coyote? I didn't feel like being cat food. I don't like guns either. -Tom
  10. I accidentally found the online course notes for a class in introductory geology. This is not the class itself but a set of Powerpoint slides that accompany the class, also available as pdf files. The presentation makes for a very well illustrated and simple overview of basic geologic processes along with some terrific animations. Well worth a look for those with an interest in geologic processes. The one that lots of you might find most interesting is on minerals at http://www.appstate.edu/~marshallst/GLY1101/lectures/5-Minerals.pdf The link below has the full set of lecture notes. Course Description Modern civilization and life in general are inherently tied to geology. This class is designed to give you an introduction to geology and geologic processes. By the end of this course, you will have an improved understanding of topics including the formation of the Earth, Earth's inner structure, movement of tectonic plates, the materials that make up our planet, the various landscapes on the surface, water resources, and the ways in which the planet has changed through time. In addition, you will become experienced in critical thinking. Yes, that’s right. I will ask you to think in this course! The first half or so of class will focus mainly on basic geologic principles, such as the Earth’s formation, plate tectonics, the rock cycle, major rock-forming minerals, and general stratigraphy. Later on in the course, we will discuss natural hazards and water resources and their impact on the landscape and society.

  11. I had posted the following in another thread recently but it did not get much traction maybe because the thread was about something totally different? LOL If you have an opinion let's hear it! This thread is not titled for experts only! I wonder if there is a difference in performance in tailings depending on the type of tailings. Do we need to differentiate between hard rock tailings and placer tailings when talking about the relative merits of PI versus VLF. For instance tailings from ancient river deposits as opposed to a hard rock tailings deposit consisting of iron rich ultra-mafic rocks. Or is it a moot point in all ground types of hard rock tailings due to no electrical conductivity in hard rock tailings because they are busted up? I think quartz tailings can be very benign almost to the point of an inability to GB on them. In regard to depth on tailings between PI/VLF being basically equal, is that true in all instances except for say a GPX or GPZ due to the battery power enabling a much higher level of gain? Like VLF = TDI but VLF < GPX? HH, Merton
  12. WOW, Just read the article in ICMJ and got to agree with Steve, good article. I spend a fair bit of time in the Santa Rita Mountains and belong to two different clubs for the claim access and can't believe how many club members will congregate in one small area, I stand there looking and think, Ya right. I usually go out during the week, when its quiet, I am talking nobody around. This is the part that really bugs me, I have found some virgin ground and small 1/4 to 1 gram nuggys, and just when you think you have found the mother load, you don't find nothing else. It really makes ya wonder how did that one little nuggy get there? Where is the rest of that little nuggys family? Ivan
  13. A mining company called Integra is offering a $1 million prize to process their 6 terabytes of data and make a new big gold discovery in a hard rock property they purchased in Canada. https://herox.com/IntegraGoldRush If anyone is into mapping, exploration, geology, hard rock mining, and data processing with computers then this may be something you are interested in. We're obviously all interested in gold already! Seems like there are a few mining engineers and geologists that post on various gold forums.
  14. Steve, Can you explain why Tailing piles are lower in mineralization compare to other areas, And would the Tailings at place's like Moore's Creek be Hotter than The Tailings Ganes Creek, What Cause's them to be Lower than the general Detecting Areas is it Because they are made up of disturbed Ground?? Thanks,,, John
  15. Spent a few hours detecting and exploring the hillsides yesterday. I first turned on the Zed about 7:30 in the morning, it was semi overcast warm and a little humid. I was detecting a huge quartz outcrop on the edge of a minor slightly eroded peak inside a series of small ravines, the solid quartz mass was 15 feet high in areas and littered the slopes, there were many such breakouts in the area, fire a few years back cleared the brush and the hills were still easy to navigate. Also a history of tunnels and hydraulicing near-by, although these hillsides were spared of that. The weather was very variable and the chatter was slowly building in the zed although I never felt it was making it impossible to read the signals, the bursts were far enough apart to tell the difference. The trash I found was all very old stuff, no gold this trip as the weather cut things short and things were nearing the dangerous side. Possibly no gold in this outcrop that may be why no washing of the hill by the old timers, or the bedrock may be to deep also the slopes are very steep here, then again it may just be that more time needs to be spent looking.
  16. The state of wy is doing a pine tree clear-cut over top of a potential gold rich zone north of the old miners delight mine, doing so in the name of better habitat for the quakies. This seems a little wierd to me, so i ask if anyone knows if removal of decidous? trees would greatly increase effectivness of such a survey?
  17. Hello all, I got out today with one of my friends and we went exploring. We were moving up a wide draw that had water running in it and came up on an inside turn where we found evidence that someone had been playing around recently. There was a black plastic gold pan lying near the creek by some cleaned out cracks. We had not found any gold yet so we decided to stop for a bit and see what was in the area. Chris used his small pick and scraped out a few shallow cracks that had moss covering them. He then panned the material out to see several pin point bits of gold. The area was worked all around by the old timers but I am pretty sure the fine gold is what they were recovering. I continued to detect near the water's edge and finally got a soft signal on the bedrock, but It turned out to be a tiny piece of lead. While on my knees and looking at the bedrock in front of me I saw what I thought was a boot track in the bedrock. In the split second that my mind was telling me one thing I was thinking another. This is pretty hard bedrock and there should be no print. Looking again I realized that was looking at fossilized ground. Checking closer I could see lots of prints embedded in the rock. I don't know what many of them are but it sure was neat seeing them like that. After playing around and taking some pictures we decided to move on and see if we could find a piece of gold a bit larger than what was in the pan. As we were going up the public side of the draw I spied a digging up the hill on the private side. We checked out our location on the phone and have it earmarked for a possible trip in the future if we can gain permission from the owner. We were real close, however without permission it was a no go for me. I would appreciate any information that anyone can offer as to what the names are for some of these creatures we found in the rock. Thanks, TRINITYAU/RAYMILLS TRINITYAU.COM
  18. Just was wondering why so many desert prospectors find good gold in red dirt/rusty quartz? Especially in Australia and Arizona deserts? I know the red is iron but whats that have to do with gold? I am sure not all reddish/orange dirt has gold so are there tricks you guys use besides just detecting and sampling to find the good gold bearing red dirt? In Indiana we look for bluish clay layers along the creeks/under rocks which can have gold bits resting on top of them, a false bedrock I guess. -Tom V.
  19. I recently upgraded to a minelab pi and cannot wait to take it out. I've been looking at a few places that are up around 7000 feet in elevation. Typically what I have read about peoples detecting tips seemed to be more focused in the lowlands. Does anybody have any tips to successfully detect at high elevations? Anything I should be doing differently or looking for? Any response is much appreciated and hopefully a few of you who work the high Sierra will see this post. Thanks
  20. How bad is the mineralization in the California Gold Country region? I cannot seem to find much information on it, but lots on the Arizona desert region. Should I interpret this as mostly VLF territory or just a lack of postings about it? I've been considering the ATX for the PI capabilities but if that area can be handled by a good VLF (GB2/V3i/ATGold) that may be preferable. Priorities for me: 1) Waterproof (I used to scuba so it may see submerged use) 2) Small-ish nugget detecting in California (primary reason for getting a detector in the first place.) 3) Surf detecting (again, see #1 just for peace of mind =) #1 is the killer - really the only other option there is a 3030 (VLF). Things like the ATGold aren't recommended for the surf and the GB2 isn't waterproof. (I used to scuba and am looking at mask+snorkel as well.) It really sounds like it's right up the ATX alley but I'm open to other suggestions. I wish Minelab would hurry up with the SDC2300 - not much info on it out there right now! I don't really want to run 2-3 separate detectors but ... /shrug. Might have to, but I'd strongly prefer to just learn one machine really really well (for now.)
  21. For an interesting read on pocket hunting posted on a Canadian forum- http://gpex.ca/smf/index.php?topic=12499.0
  22. Hello Cy, it is very difficult to try and narrow things down for you. The problem in trying to discuss pockets or lines is that they show up differently at different locales. I can tell you what to look for here at my location but it may be completely different where you are at. We both may have opposing geology while we may also have some similar features. When I take a person out training I try and show them what is happening on the ground. The geology of your local area may be different but the set-up in my mind is probably pretty similar anywhere. Let me try a different approach. Lots of people are on the lookout for a contact zone. This is good but too many people read too much into it. Some will see a quartz stringer running across the surface and call it a contact zone. While this may be true to an extent there is bit more to it. The area that I am located at has a general push from the NW to the SE. This push is the general direction in which the most prevalent base material is heading. In my neck of the woods this is shale, any color shale. So, as I am walking along I am watching the ground near and afar and seeing that common trend from NW to SE. While walking I notice that there is a dike or a seam, whatever you want to call it, of a different material crossing or cutting the general trend of shale that I have been looking at. This different material can be three feet wide or thee inches wide or it can be tiny seams that are matchbook wide, does not really matter. Here in my area it is usually Granite, Diorite, or Quartz and I have even seen shale crosscutting shale. As I stated earlier what you are watching for is the odd body of material that is cutting your general trending material. Once I have come across a location like this I slow down and try to find its limits. At times an area can be very small and precise while at other times the area could be very large, literally square acres. Let me break down (limits). When you have one material crossing another, let's say shale being crossed by diorite, most times you will have a change in the color of the immediate and surrounding area. I try to line this area out so I can determine the likely erosion path. Remember, what is the down side of a hill now might have been just opposite millions of years ago. Finding these limits can be very frustrating when you are in an area that has lots of grass and foilage. Sometimes you will have outcroppings of the crossing material and this can really help to identify a direction. This may sound way out there, but there are many types of vegetation that grow only in certain ground conditions. This too can be a possible lead to a location. Once determined what direction that erosion has taken place I start to detect. If I am on a slope I go down the hillside several hundred feet and then start back up detecting as I go. I like to zig zag across the slope until I come across that first piece. At that point I start to concentrate on that area and up the hill. Yes, there are times that I do not get a piece and I may have to change my hunt tactics and become a little more intense with my search efforts. Of course there are times that all the pieces of the puzzle come together and there still just is no gold to be found. This happened to me a lot when I first started detecting for pockets. After a few years things became clearer and began to go my way. Once on a line/pocket you can almost run it out with a compass. I am talking about a sometimes straight line that will throw detectable gold on the surface accompanied by a clay or ironstone seam. These lines or pockets occur around the contacts that I have mentioned and can be traced for miles. An interesting scenario that I encounter in my area is that a lot of the most productive areas that I have located seem to always show up on the southeast facing slopes. So much so that I tend to seek out just those slopes. Many people are too engrossed in looking for the quartz on the surface. In my local area there is virtually no quartz at many of the locations where pockets or lines have been found. This brings me to another point. When I say pockets most people are thinking of a single location where gold has been trapped and found, such as a crevice in bedrock. Others are thinking of an enriched zone of a vein that has pocketed out and left goodies behind. What I am after when I say pockets are these lines or very small areas that run immediately below the mentioned contacts. Are they worth it ? I think they are and many of my friends have learned over the years to become "one with the dirt", and the gold starts to show up. I will say that this may just be an anomaly to the Redding,Ca area but I know that is not true. I have done the same thing in other parts of California, Nevada and Oregon. It is not easy and it can be really frustrating but it has been very rewarding for me over the years. This is a different type of hunting. I do hunt the old diggings, ground sluice operations, gullies and creeks, hardrock deposits and any other locations that the old timers worked but I like the thrill of finding gold in places where no one is looking. I hope this helps some, these are my thoughts from thousands of hours on the ground that I have hunted for pockets and lines. TRINITYAU/RAYMILLS
