Q: Fran asks: Hi Prospector. Jess, I really liked the videos outlining how to track a pay streak in the river curves. I am about one year into prospecting and this revelation really tweaked it in for me. I have a question , I read somewhere that the most valuable Gold is not yellow in color. I believe that it stated that it is black and very dense as well. It is described as the Elvis Presley of Gold and is extremely rare. It is most often chucked aside mistaken as unwanted heavy s. Do you have any info on this Gold?
A: The most likely dark or black looking gold like nuggets that were often mistaken for lead and lead shot is platinum in the form of small platinum nuggets.
The old timers had no idea this stuff had any value so they threw it out as they would lead. I’ll post some pics on the site so you can see what it looks like. See below.
By the way spot Gold is now at $1743.40 USD/Oz and platinum is only $1633.49 USD/Oz typically platinum has been higher so you may see it move up along with silver to catch up with golds price rise.
All the same keep an eye for small elongated silver-gray nuggets that seem quite heavy for their size, could be platinum. Usually there is a history of platinum and related metals in the streams where you find it. Pure platinum has a density of SG=22 or so depending on iridium and osmium in the alloy where pure gold is around 19.3, so yes it is quite dense in fact platinum is about twice the density of lead.
