Interesting, but you just have to keep in mind the definition of reserve, where profitability is part of the calculation. Also reserve does not tell much about extraction.

That may be correct, but recently it looked like this:

Also you are directly dependent on the country where you get your uranium from. Which for Europe was/is mostly Russia. That also does not seem a good idea.

It does not very much look like pyrite in OPs picture. The rock does not look very much like ore and with pyrite you’d often still see some crystals, which look like small golden cubes.

For clarification: Most of what you listed, are minerals. Rocks (like schist) are usually composed of different minerals.

Best guess I can make is, that your rock is some kind of schist and contains quite a lot mica. From your picture it does not look very much like pyrite.

The glitter from your rock, especially if it looks like small sheet like flakes is very likely the mica or some other sheet silicate.

That it breaks down quite easily may be a sign of weathering.
