The Saucy Lass occurrences are located are located on Cass Creek, approximately 800 metres north of the creek mouth and 29 kilometres southwest of Port Alberni.

The area is underlain by the contact of Upper Triassic Vancouver Group, Quatsino Formation limestone and volcanics of the Lower Jurassic Bonanza Group. Intrusions of black igneous rocks are found in the immediate vicinity of the skarn deposits. These black rocks have a gneissic structure and are considerably sheared locally.

Locally, several occurrences of chalcopyrite ore associated with magnetite, garnet and epidote are reported.

Development work, done prior to 1920, consists of 3 adits; one is 18 metres long and the other two are 3 metres long each. A selected sample taken near the portal of a short adit assayed 14.5 per cent copper, 27.43 grams per tonne silver and a trace of gold (Minister of Mines Annual Report 1920).

In 1988 and 1989, Barona Resources completed programs of soil and rock sampling, geological mapping and ground geophysical surveys on the area as the Gold Nugget claim.

In 2007 through 2013, Nahminto Resources completed a program of prospecting, geological mapping, geochemical sampling, a ground magnetometer survey and airborne geophysical surveys on the area as the TJM claims, part of the Nahmint property. In 2009, a sample (200925) of mineralized skarn exposed in a creek canyon assayed 0.8 per cent copper and 6.1 grams per tonne silver (Assessment Report 31248). In 2013 Equitas Resources Corp. conducted geological mapping, rock, soil and stream moss mat sampling at the Three Jays North area of the Nahmint property.

In 2020 a structural analysis via photo interpretation and minor prospecting and stream and rock sampling were conducted on the Nahmint property for tenure holder B. McKinney.
