interesting experiment which did not yield quite what I thought it might.
Soaked this rock
in strong hydrochloric acid solution for a few days wondering if it would penetrate the entire rock or only cause a superficial exterior change of appearance. I haven't got as far as trying to break it because this is what I found.

appears to be tiny grains of gold colored metal.

Interesting. With a very sharp pin, see if you can spread one of those metallic flakes like butter. If yes, go collect all of that kind of rock that you can find. Better yet, try to find its source.

soft and smeary, yep. The tiny clear colored crystals which are also inclusions, the black crystal inclusions and the small yellow (like epidote) blotches are all hard and not movable. glacial erratics. no telling their source, but somewhere "up north" of here.
