matt Posted August 7, 2010 Report Share Posted August 7, 2010 I have a question. Does anybody know a person or company that will hydroflouric acidtreat a specimen nugget? I have a family and live in a populated area and just don'twant to risk having that stuff around. I would rather pay somebody to do the dirty workfor me. Also, most acid treated specimens that I have seen usually have some chalkyquartz still attached to them after treatment. Can the quartz be completely eaten awayor will there always be some residual left? Thanks for any help.Matt Link to comment Share on other sites More sharing options...

Uncle Ron Posted August 7, 2010 Report Share Posted August 7, 2010 Hi Matt & All...I used to do the acid bath in our mining lab quite a bit...It is very nasty to work with so you need a lot of protective gear and procedures ... I was successful in completely removing the quartz in many instances ... unfortunately, in about 2/3's I ended up with a pile of gold crystals instead of a nice crystally nugget ... Also, if the speci has other material in it besides quartz you can end up with a very ugly still-speci ... But those nuggets that worked out were real beauties and sold for a couple times spot or more ... Cheers, Unc Link to comment Share on other sites More sharing options...
matt Posted August 7, 2010 Author Report Share Posted August 7, 2010 Thanks for the answers guys. Gary, I never thought about talking to Steve.He and I are friends, but I have not talked to him in a month or so. I have beenbusy working and he has been busy finding gold with Lucky! I'll have to seeif he knows anybody using the stuff. I also have a goldsmithing project forhim to make. I did use an multimeter meter on this specimen and most of thesurface gold is connected on all sides. I think there is a large gold chunkin the middle according to the specific gravity test that Reno Chris wrote aboutin the ICMJ. Also, the response my detector gave to this specimen makes me feelthere is a large mass inside of it. Thanks again guys.Matt Link to comment Share on other sites More sharing options...
grubstake Posted August 7, 2010 Report Share Posted August 7, 2010 I think Steve would be your best bet. Why not just get him to slab it, its worth more by the gram that way, if its spiderwebed enough. Good luck on it Matt. Gary I was going to tell you to take it to your local VET. and see how much they would charge you to Xray it, then you will know what you have inside.

matt Posted August 8, 2010 Author Report Share Posted August 8, 2010 This specimen is not a new find. I found it last season, a few months back.I have several that would be great under the saw, but this one is a littlebit different. I think it would be better acid treated. The gold is not spreadout and very little is showing on the outside.Steve, this find was from a new patch on a different property. I really hopeto get up and check out the cave soon. I still want to have you make me thering we discussed. Also, that slab from a specimen you cut for me a couple yearsago will make a pendant for my wife.Matt Link to comment Share on other sites More sharing options...
grubstake Posted August 8, 2010 Report Share Posted August 8, 2010 I don't know that might surprise you, if it was slabbed up. Nice looking. Grubstake Link to comment Share on other sites More sharing options...
matt Posted August 8, 2010 Author Report Share Posted August 8, 2010 I like your idea about the x-ray at the vet Gary. Then I would knowfor sure what it looks like inside. Thanks for the comments. Maybe oneday we can get in a hunt together? Take care.Matt Link to comment Share on other sites More sharing options...

Hawkeye Posted August 9, 2010 Report Share Posted August 9, 2010 I have a friend that has done several for me and I know another guy that will polish most of the chaulky quartz off, results depend on the specimen.Wes. Link to comment Share on other sites More sharing options...
