What did I find!
« on: March 05, 2018, 04:35:49 PM »
This one is confusing me a little.  It is the right colour for gold,
It washed out below the black sands like gold.
But I have never seen this type of structure on gold before.
I have not yet tried it in an acid.  That would be the next test.
This piece is about 1/16" and quite round.
Found on the Fraser with a bunch of other gold, all more typical looking.

Thatís unique Dan be interested to see how it reacts to acid . Will be looking forward to what you finally come up with.had something similar I found in some shale . Same bubbly effect gold colour . Had it checked out by a lab .turned out to be pyrite , and some silver. Not high enough numbers to worry about on silver. Hope your sample turn out better. Isaac

Mcbain, the thought did cross my mind.  I have got LOTS of mercury before all over.  I was wondering if this was a bunch of gold amalgamated into mercury and then some natural process driving off the mercury leaving just the gold behind.  That might account for the round shape.  But if this is the case I would assume I would see more like it around.

Not Mercury x Gold or Silver or Copper amalgam.  If it were even the least of an amalgam there would be a silver (Mercury) coating over the entire specimen.   To prove that, soak in a few drops of Nitric Acid.  If Amalgam then the Nitric would remove the Mercury and carry it, suspended, within the Nitric as part of the fluid.

I know what mercury looks like on gold.  I was more thinking amalgam after the mercury was removed.  I'm not sure what temperature mercury starts to evaporate at, but this was on a south facing, black shale, bedrock face, near Lytton.  In the summer time you could fry an egg off these stones.  I wonder if it is hot enough to vaporize mercury.

Hi.Guys.This is probably not  the case.But remember a few years back,I made a post about a machinist working in  the interior that could not get a claim and was peeved.He bragged about dumping stuff from the shop into the river just to screw with folks.This guy is really twisted.He dumped a lot of brass and other alloys.Brass will turn green under normal circumstances but I think washing  downstream with sand and rocks would tend to keep it shiny.This is just a reminder of some things you may find south of the Caribou.Luck,Mcbain.

Brass, like Copper turns green as it oxidizes in atmospheric contact, the Tin in the Brass slowing the oxidation somewhat.  The first sign of oxidation should be a dulling of the surface like the old, copper cents from the Canada or the US.  They started out shiny Copper, then through contact with salt from handling, atmospheric moisture and Oxygen would turn brown and then eventually the Verdigris would appear from chemical reactions between the three "players" (mostly salt from handling).
