  1. I sent in a sample to two different assayers out of the same sample batch and received two very different results. One assayer returned results of 0 Au and 0 Ag. The other assayer returned results of .68 Au/ton and .36 Ag/ton. Anyone have some serious thoughts on what would cause this? Both assayers are professionals with 30+ years of experience. Bugler
  2. Hi, Is it possible to obtain silver and gold metal of the Byzantine and Roman period iron ore?

  4. "Cell phones are a gold mine. Really. According to the EPA, for every one million smart phones recycled, 75 pounds of gold, 772 pounds of silver, 33 pounds of palladium and more than 35,000 pounds of copper can be reused." http://www.oregonmetro.gov/news/when-gadgets-become-garbage-how-recycle-electronics
  5. My little kiln arrived from America and I gave it a workout the same day then sold the gold the next day. I used the chapman flux supplied and only lost a few grams. The purity was around 88-89%, the rest silver. Pulled in au$9,742 @ $48 a gram, spot at the time was $52. Happy with that. Try as I might, it just will not allow me to post a photo 😳? Submitted the post then hit edit and the photo option worked.
  6. Sittn here thinking about my "test" nugget 2.7 gram chunky solid bit I "bought off ebay to test my GB2/gpx45/sdc23 with.....I'm a newbie ' but have watched nuggetdiggs" on youtube . and watched thousands" of vids in 9 years! Thats Alot of Gold coming out of the ground! But it never crossed my Mind till tonite......Whats the Grade??? And how does the Western US compare to Australia, Alaska, Africa? My little noug' looks light yellow slightly silvery 14k-16k i'd guess supposed to been found w/ a metal detector in,Nor.Cal. "Must be Dale's Hands from Goldhounds ...Made it myscreensaver " last nite! Is All gold mostly higher grade than what i got for $165 shipped off ebay?.........just wondering? Thanks from central Idaho-JD
  7. Hello all, I'm in search of someone who can refine my placer gold into an 18k alloy. Does anybody know a reputable person/small scale business that could do this for me? Thank you!
  8. I was visiting a customer of mine today and he had a ThermoFisher XL3 XRF - I believe someone, possibly Steve, had posted about this technology a while ago. I happened to have a hunk of manganese loaded quartz in the trunk of my car that we tested it on...absolutely remarkable. In a matter of seconds it will display everything in PPM. When this technology gets to be around $5K +/- I will definitely be investing (The unit that he let me try as configured cost over $30K.) If you had a serious size lode claim this is something I would think most individuals would want to take a look at.
  9. Hi,guys! I want to receive an expert advice. I’ve got some old electronic equipment (of Cold War times, came from USSR) and want to remove gold from the contacts. What can you say about this equipment http://www.ishor.com/refining-and-recovery/refining-systems-processes Is it worth the money? What kind of equipment you can recomend?
  10. Curious as to the meaning of some Atomic Absorption Analysis assay results I am looking at, any help would be appreciated. Specifically the last line "AuSw" appears for these samples only, none of the other samples have an AuSw line. Some of the other sample results came back with higher ppms for AU but no AuSw line? These are from quartz vein grab samples containing copper and iron oxide. Sample from AA Assay.pdf
  11. Anyone have any experience in figuring out a odd metal we keep finding in our cuppel? We have been assaying our cons from a lode mine. We take a 30 gram assay and once we have our lead button that goes to cuppel we end up with 16-20 grams of a very heavy gray/silver button. For it's size it is as dense as gold it can't be silver. The ore comes from the sulfide level but is not a sulfide. It does not roast off and under a microscope its a silver/metal. Wish I had a xrf and that would be the end of it.
  12. I'm ultra sketched out mailing off big slugs but the time has come and needs to be done. Anyone out there using a refiner they've done business with and trust? Some of the joints I found online look fly by night and none are close enough to visit in person (actually some don't even allow visits). Hoping someone out there has some positive experience.
  13. I guess the streets really are paved with gold - sort of. http://nypost.com/2011/06/20/got-his-mined-in-the-gutter/
