It's tough to tell from the pics, but I bet it's a piece of either granite or basalt. The texture looks like basalt sort of. I dont think there is copper in that. I dont believe it's a geode either, but you never know. Usually geodes dont have external Crystals on their surface.
Shiney lime green crystals are probably olivine. Feldspaar is usually pink or creamy colored and has a very distinct grain pattern with near perfect 90° cleavage (fractured edges, not boobs)
Get some closer pics of the granular structure and I might have a better idea. Or take it to a school with a geology dept, as noted before. I did take a few geology classes in college.
I've found silver ore in a limestone rock in southern KS. You just never know what you'll find. We have a ton of these big red quartzite boulders, some the size of houses, scattered around the northern half of the state. They came from areas around the Great Lakes during the last glacial age, in which the glaciers terminated in our area, and dropped them.
