The Mispickel deposit, part of the Yellowknife City Gold Project, is contained within a wide deformation zone containing shears with abundant narrow (1-50cm) quartz veins that contain coarse-grained visible gold and low to moderate sulphides (arsenopyrite, pyrite, pyrrhotite) within subtle chloritic and sericitic alteration. The zone is hosted in turbiditic sediments of the Walsh Lake Formation. Units within the formation show abundant tight to isoclinal folding with probable N-S shear attenuation along fold planes. 

On weathered outcrops, 2-7m wide oxidized and highly fissile shear zones are evident. Quartz veins have biotite ('salt and pepper' veins) and can assay up to 300g/t Au over 1m. 

Although Mispickel only has a modest inferred resource of 64,000 oz Au, several indicators that are being teased out of various datasets suggest that Mispickel is larger than currently realized and that there are likely several other nearby zones like Mispickel, hence the new language of referring to Mispickel as a system.
