Found this stone, any idea of what can it be?

Granite conglomerate?

Hmm, I googled for granite conglomerates and they look pretty different, but I'm concerned about the minerals in it, there are traces of golden things, very shiny and it doesn't seem to be pyrite. I can identify feldepast and maybe some quartz...

Can you provide more detailed photos of the mineral areas? If it's real gold it'll be pretty soft (malleable). You should be able to scrape it with a nail or something and get off flecks of the gold.

calcopyrite

i think it's Pyrite Or Chalcopyrite
