Found this today and wondering if anyone can give me info about it. Its layered dark and light, a thick 1cm wide layer of 1mm pyrite cubes visible along with thin lines of micro pyrite. Some of the dark lines are straight, some wavy ( these smaller lines are around or under 1mm )
After a pan and crush of a 2" chunk. See the sulfides / pyrite crystals and dust to the left. Lots.
The bits I got
