The Why Not shear trends northwest and dips northeast in altered quartzose diorite of the Permian Bralorne Igneous Complex before fraying out in sheared altered serpentinite of the President Ultramafics (correlative with the Permian and older Shulaps Ultramafic Complex). The en echelon veins are composed of white, massive to crystalline and sometimes drusy quartz, a few centimetres to a few metres wide. Rock inclusions occur between split veins. The quartz veins are well defined and poorly mineralized with only local gold values. The Why Not workings coalesce with the California workings to the southeast (see 092JNE020). Where the two veins intersect, high gold values are reported.
