Is that gold in the tiny rocks? Is sapphire in those samples as well? 73, Mike

Now go beat the copper out of something, Miked

To the naked human eye it looks like black sand, under the scope you can see different crystals. I suspect there is some micron gold in the sample. I do not know what the other crystals are but did not see any diamond indicator minerals - Chrome diopside has a beautiful rich green colour.Originally Posted by miked
But then I'm not looking for diamonds, what I want to know is there enough gold in the Northern BC black sand to make it worthwhile to smelt. Fortunately my studies are gold, silver and platinum group related. Otherwise I might not live long enough to learn everything microscope related.
I need to figure out a better lighting system to eliminate the shadows, next is to make a Linear Polarization filter.
This short tube video explains the use of polarized light far better than I'm able.
On a side note you'll often find a Linear Polarization sheet inside old laptops and flat screen television sets, check out ebay for resale value.

Short video showing how light interacts when I rotate the linear film 180 degrees out of phase, watch unto the end.

Magnetic fraction removed, two different light sources.

Take it with a grain of sand, single grain loaded with micron gold.

The linear sheet from flat screen did not work for my intended purpose, I think they're using this type to focus more sunlight onto solar panels. Do your own research.

Learning some amazing things, top image shows me there's gold i this black sand sample which has been proven by leaching in acids, the sample below is from another location hundreds of miles south from where the first sand came from.
The second sample contains mostly platinum.

I received another sample of black sand which came from an area hundreds of miles south of where the first sample came from, much to my surprise the same volume of sand from each sample provided an interesting observation when weighed.
I'm not claiming the extra 2 grams is gold, but its obvious there's something in the first sample to make up the extra weight.
