Quartzite with some copper mineral (based on the green color)? I've definitely seen both massive and non-massive quartzite, and the hammer scratching/ non-HCl reactivity seems indicative.

The green mineral is the tricky bit- if it were a copper mineral, I'd be hard-pressed to say whether it was a sulfide or oxide. The schists and the (what I think is quartzite) slightly bias me against the copper being a sulfide from a hydrothermal system, and make me think it's more likely disssolved copper oxides deposited in the sedimentary protoliths by water moving through the rock.
