The Crinkle Quartzite occurrence is located between Mount Francis to the east and Swift Lake to the west, about 107 kilometres east of the community of Atlin.
A showing of minor sulphide mineralization and copper staining (malachite) occurs on the west end of the low ridge containing the Arsenault showing (104O 011). The Arsenault showing is 3.5 kilometres southeast. The Crinkle Quartzite locality is below tree line about 2 kilometres west of the old exploration camp where a few chalcopyrite veins up to a centimetre thick occur within the upper third of a 10-metre cliff exposure of crinkle quartzite of the Paleozoic Big Salmon Complex. No signs of prior sampling are evident.
