I see quartz and pyrites. It is possible the pyrites is actually chalcopyrite (the copper-iron pyrites rather than the plain iron pyrites). I suspect the rusty brown matter may be decomposed chalco-/pyrites. So it might be reasonable to consider it copper ore.
yes copper oxidezes green = malachite richer coppper ore but chalcoopyrites oxides to brown sometimes peacock ore purple gold colours it has a mix of copper irons silver and sometimes tiny gold silver etc
pure pyrite turns to linonite more ochre / lighter brown
