Sure looks like Eloise ISCG, hopefully much bigger without complicated faulting. I have way less knowledge in geology than many around these traps, but after 20yrs of playing with resources you get a smell of what's average or not.

"Ore mineralogy is almost exclusively chalcopyrite with the principal gangue phases consisting of pyrrhotite + quartz + carbonate. A biotite + hornblende + magnetite assemblage represents locally intense mafic alteration of the metasedimentary host sequence. Magnetite is present in variable amounts and may be locally significant in some of the smaller satellite orebodies. Within the orebodies the sulfides display a range of textures from massive through to vein like. Sulfides commonly display brecciated textures at a range of scales."
