    I'm retired, my wife is from Shanghai and we have homes in both China and the USA. My family came to California in the late 1840's from Europe, Ireland, Italy, Croatia. One side took up dairy farming on the coast, my great grandfather on the other was a gold minor and inn keeper in Jackson, CA.

  1. GPZ gets 40% more opal, I wish. One of the terrific members in my club donated that beauty for our veterans raffle and I had the lucky ticket:-)
  2. Azdigger, I can't help you much as I'm very new to this game as well and also ask myself what the heck am I looking for everytime I'm out. Red dirt in some areas and white patches in others. Differences and junctions of the soil colors, signs of fractures...streams appearing or slipping underground indicators of fault lines and the almighty quartz float and serpentine zones, gets my head spinning. I'm looking for them all and they seem to be everywhere, fortunately (depending on how you look at it) a lot or most of the gold proudicing ones I think have been discovered and some trace of their location marked by previous activity and in saying this know I'm not saying anything you and most everyone already knows, this is question as much as statement... in saying this all of my nuggets have been found by confidence. All have been found in heavily pounded ground and only after forcing myself to pick an area and slow down searching inch by inch for the remaining spread out nuggets in worked ground. I just got back from rye patch and 4 full days of hunting reallly good looking ground and on the third day hit one .7g nugget for the trip and I'm happy as hell, my last two trips were skunks. The shiny flat gold, coins and Opel were from the club rye patch outing, the one covered in calcite is the .7g after a bath in CLR I found. The jeep tire was just another part of the adventure and a chance to make a new friend at big-o-tires in winnemucca, also stopped in to see Peg Leg John on the way back to rye patch, john's always a friendly face and a few good stories. Anyway I diverge, again all my nuggets I've found going slow, really slow and in spots I've cornered before that I missed more than once on previous trips. Another half of those in tight spots, under obstructions that make it tough for good coil swings and thus more likely missed. I'm new, this my disclaimer if I lead you astray... hunt worked areas, I look for old and new dug ground and I follow any tracks I find and go slow. Not saying that this isn't what you are doing now, probably you are, really most all my time is enjoying the hunt with scarce seconds of euphoria...great isn't it. Best of luck, clark
  3. For the first year, year and a half with the 7000 I never used my pinpointer, then after trying it and seeing no problem interfering with the gpz it saves me recovery time. mostly with shallow trash I can pop the target quickly without any digging and chasing small targets in a large 7000 dig hole is usually much improved, at least for me anyway.
  4. I have the trx and use it with the gpz, good depth, one touch gb, plays well with the gpz it doesn't interfere although the 7000 needs to be as far away from the trx when pinpointing as the zed lights up the ground and affects the trx causing it to false. I run my trx fairly hot, so that contributes to the false signals a bit too. I also have the new Deus pinpointer, but have not tried it with the gpz.
  5. Al, thank you... I think it's helpful when the thread story is complete even with the disappointments. Hopefully my failures help others in their search for answers as I know everytime out adds just a bit more understanding to my database and someday when I've gathered enough pieces of the puzzle I can graduate from complete new guy to green horn...that would be sweet.
  6. OK, so I've taken the xrf results and after much interesting reading I'm still very confused, but learning some new things that will stay somewhere in reach if ever needed again. In reading history and chemical composition of steel, ranges of Cu .5 to 2 percent and Mn at .5 to 13% and Ni in the low percents was a good mix for the military munitions. So, based on the xrf results and the shape of the metal it now looks to me like a small military bomb fragment? The only thing is I'd expect to find many more pieces unless they have all been recovered over the years?
  7. Finally got around to having this little mystery xrf analyzed at a local pawn shop... Ni 1.53%, Fe 96.76%, Cu .54%, Mn .917% nickel I think is borderline low but I have not been able to find results for confirmed finds from the same area, also the exposed area and what is revealed by filing may affect results? Anyway that's what their equipment analyzed it at. clark
  8. his add is back up today, now the name is Kurt... could also just be a phone/email scammer trying to collect data to sell. http://sacramento.craigslist.org/for/5317159503.html
  9. posted today on sf bay area crags list, don't know anything about this listing just an fyi; GPX 5000 metal detector - $1 Have a metal detector for sale. Need the money ASAP. Contact me by phone only. Shoot me a price and we can talk about it. 916-561-9396 my name is Logan. Call anytime.
  10. put some sulfuric acid on the window polished into this specimen and it shows a rectangular band and some small striations. still have not taken it to have the metal tested. not that it means anything, but the piece this guy found looks exactly like mine in every way and they were found within a few miles of each other, so they came from the same source at least (the same tractor???), so who knows... time for the next test. A new ---and very tiny--- Majuba??? October 21, 2005 Northwest of the Rye Patch Reservoir on the north side of I-80 between Lovelock and Winnemucca, Nevada, is an area that has been hit hard for gold nuggets ever since metal detectors were invented. The nugget patch is spread in spots over an area of 15 to 20 square miles. It has been hit very, very hard for a very, very long time with every successive generation of metal detecting equipment. Now, most everyone in the meteorite community knows that it is virtually inevitable that an area of this size hit this hard for this long WILL yield meteorites. It has. I don't know the full totals, but I am aware of no less than 6 finds (and these may all be paired). For about 3 years, whenever possible, I have searched all over the area without any luck (except for about 20 nice gold nuggets). Recently several key lines of evidence converged. After a lengthy embargo, locations were published for Majubas 1, 2, and 3 in the latest Meteoritical Bulletin. Then, in April, John Wolfe found two more, one of which is currently offered for sale through Anne Black's Impactika website. The latter includes a photo of John in the find area. I plotted the coordinates for the first three, printed out a photo from the new finds, saught the matching location, and found that all were in a very small area in a part of the nugget patch where very few nuggets exist. I had never worked that area before. The meteorite find area is in the form of a triangle about 2000 feet on a side. The piece described here was found near the center of this triangle. I worked back and forth between the various find sites with a Fisher Gold Bug-2 metal detector and over a period of about 20 hours found one suspect speck. I may be nuts, and a Ni test is still pending, but I think this is real, and if so, certainly the smallest Majuba yet! (Be certain about this: it was NOT my aim to find the smallest ever. I was kinda hoping for what the Franconia folks (Asher, Baird, & Ortega) just found (mid-October)--- about 600 pieces/26+ kilos in an 800 square foot area!). Oh well. One must start somewhere. Here it is. My newest pride and joy. Don't laugh--- Okay, that's pretty tenuous for a visual identification, but this thing screams in the metal detector. It is very strongly attracted to a magnet. And when I stroked it on a diamond file, this is what I saw: When a stony explodes and goes mostly to dust, the biggest surviving fragments in the dust cloud would be expected to be high-tensile-strength metal blebs, and this looks like a winner. I have found all sorts of cast-iron bits and welding beads and other assorted scrap metal in the general Majuba area, but none look like this, and there is almost no junk metal in the meteorite patch itself.. Check out that metal texture. About 40% of the mass flaked off as "shale" flakes while I filed it (these are being tested for nickel). What is the lower size limit for a new meteorite find???? This may well explore the limits. It weighs about 0.1 gms ( including the shale) and has a maximum dimension of about 4.3 mm. That's about the size of a BB, but half the thickness. (In the image those are scratch marks from the file showing in the metal). Don't raise your glasses till we do the nickel test, but I'm willing to bet this is the real deal! Say hello to the tiniest Majuba ever! If this is paired with Majubas 001, 002, 003, and 004, it is a fragment of an H4 Ordinary Chondrite. Cheers, Norm Lehrman
  11. thx, mn90403, they would need to know for sure. I remember some buyers were fooled by a scam a couple of years ago, a guy took genuine swiss bars, cut them in half, machined them hollow and filled them with something, i don't remember it being lead. when they were finished you couldn't tell they were tampered with and they had the proper certificate, a whole lot of them were on the market.
  12. DolanDave, thank you, if i can't find anyone in the local area when i finely get around to it i may take you up on that.
  13. I have ferric chloride in my studio, it is used raku firing ceramics. when using ferric chloride it is sprayed on the pottery just after pulling the piece from the kiln when the glaze is molten. its call ferric chloride fuming, just as red heat begins to fade around 1100 f, ferric chloride is sprayed directly on the still glasslike surface and produces a very attractive luster to the ceramic glaze. I get it at radio shack so I imagine it is the same stuff.
  14. This has nothing to do with meteorites, but rocks are rocks and if you like one type odds are you find interest in another. I have many friends in china who own factories and are some of the most respected carvers in the country. if you take a look on my jade website you can see some of the carvers and studios on the blog page (some of my ceramic work is hidden elsewhere on the site as well). the work under carvings are examples of the work they do, all of these pieces are now in private collections. I don't do sales from the webpage, but i do answer a lot of questions from people from all around the world about jade. Ive looked at thousands of pieces and have a little better idea of what I'm seeing (unlike meteorites) and then I send pictures or samples to my friends in China for conformation, jade is also very difficult and there are many pitfalls and millions of dollars are lost by people way more knowledgeable than me, so I always check with China to be sure. anyway, if I can be of any help and an information resource to anyone on the jade end of things, let me know and I will do the best I can. www.thejadedealer.com
  15. Thanks guys, as an educational thing for me i really appreciate all the great help and advice... as i was polishing it down i was disappointed to see the inside not match the outside, because of the outside oxidation pattern i expected some coarsely mixed granulation, even though as i read the information i now know the material can become visually homologous until etched. if the outside texture (fusion crust) was influenced by the inside material independent of atmospheric contamination as in the case of meteorite there would be a direct relationship, right? earthly objects would tend to look like this one. the only thing going for it is the thin layer of black oxidation between the rusty outside and the shiny inside, it resembles something i commonly see where there is non-ferris metal tarnish, but 2000 grip sandpaper can make dried dog crap look like gem stone if you are careful i'd guess. the cost of testing is negligible, so for the sake of taking the mystery to final end it might be fun to see what year of tractor this broke off of and test the alloy. I don't feel to bad, i think this would fool quite a few and I enjoy the heck out of this so i know it won't be the last piece of junk to find a home in my pocket. thanks again, life's a journey clark (this took to long to write)
