Disseminated-style (Carlin-type) gold deposit, occurring in a Middle Devonian to Lower Permian turbidite formation composed of quartzose sandstone, siltstone, slate and limestone. Gold is mainly present as invisible gold (as is typical for Carlin-type deposits), but very fine-grained native gold can be occasionally seen under a microscope.
