boulder dash Posted July 11, 2014 Share Posted July 11, 2014 Bet a quality detector could pick that thing up from 6 foot. A guy would need a backhoe to recover targets. Quote Link to comment Share on other sites More sharing options...
Rimshot Posted July 11, 2014 Share Posted July 11, 2014 Wow!!!!!! Just think! That's equivalent to 4495 copper pennies. But I wonder what nugget like that would be worth... Great conversation piece for sure! Quote Link to comment Share on other sites More sharing options...
Rimshot Posted July 12, 2014 Share Posted July 12, 2014 (edited) Just wondering here...has it been checked out for gold content w/d mixer? Edited July 12, 2014 by Rimshot Quote Link to comment Share on other sites More sharing options...
wet/dry mixer Posted July 12, 2014 Author Share Posted July 12, 2014 No it hasn't, its as it was when dug-out. Know of some rocks like the nugget north of Yuma, but they have sharp edges and never been tumbled, they assay copper, gold and silver.bob Quote Link to comment Share on other sites More sharing options...
Au Seeker Posted July 12, 2014 Share Posted July 12, 2014 If that copper nugget is from Michigan, it could but most likely doesn't have much if any gold content, I know that there is a little gold to be found in the UP of Michigan but there is a lots and lots of copper in that area, with large nuggets still being found and some of them are huge!http://americanprofile.com/articles/large-copper-nuggets-still-discovered-in-michigan/"Large-scale copper mining ended in Michigan’s Keweenaw Peninsula decades ago, but large copper nuggets are still being discovered. In June 1999, Mark Mattfolk unearthed an 8,640-pound copper mass with a bulldozer while logging on his property near Dollar Bay (pop. 950). The giant nugget is on display at the Keweenaw Gem and Gift shop in Houghton."Here's one that is in the Smithsonian..the "Ontonagon Boulder" , it weights 3708 lbs.http://en.wikipedia.org/wiki/Ontonagon_Boulder Quote Link to comment Share on other sites More sharing options...
mn90403 Posted July 13, 2014 Share Posted July 13, 2014 (edited) I met some people at the Tucson Gem and Mineral Show and I bought a 4.4 lb copper nugget for $80 but it has be processed in a way that brings out the copper. It looks better than these pictures I just took because the green shows well. This company had many, many nuggets and I think you can collect them on your own and I probably could have beat them up more on the price but they have expenses too.Mitchel Edited July 13, 2014 by mn90403 1 Quote Link to comment Share on other sites More sharing options...
