Another example of the gold after being abraded off the board by the chip dust. The nickle layer is there to keep the gold from migrating into the copper layer.

Gold is a soft metal which is easily abraded off.

The finely milled silver being hydrophobic agglomerate on water and does not disperse, the material easily skimmed off.

Might be some gold in the float.

Silver reacts with oxygen, tomorrow I'll add some hydrogen peroxide then stir the pulp with a dry wall mud paddle.

From the above post, a pound of unrefined silver.

More chips to mill this time added some silver plated flatware to see if the silver will abrade off.

When I lived in Tennessee I did a lot of caving and saw quite a few confederate bat guano saltpeter mining workings from the civil war.
There is several salt peter caves near me. One is flooded and we dove in and got the large hand drill bits but stirred the botton and up came methane gas and we retreated.. Lol
