The TL claims are located on a tributary of Tsuius Creek, 41.3 kilometres east of the community of Enderby.
Regionally, the property is underlain by the Paleoproterozoic Monashee assemblage of calc-silicate–marble, quartzite, biotite-garnet-schist and paragneiss; Tertiary Ladybird granite intrusions occur nearby.
Locally, a 10 to 20- metre wide zone of pyrite, pyrrhotite and sphalerite mineralization is hosted by a quartzite that is conformable within a host succession of calc-silicate–marble, biotite schist and micaceous quartzite. The mineralized zone has been confirmed over a strike length of 80 metres, for a depth of 20 metres and is open to the south east and north west. Another mineralized gossanous zone is reported 200 metres to the south east and may represent an extension of the main zone.
In 2011, channel samples of massive sulphides assayed 8.98 per cent zinc over 3 metres, while anomalous values in molybdenum and rhenium of more than 300 parts per billion, with a maximum of 1339 parts per million molybdenum, were also noted (Assessment Report 34329). A separate zone of disseminated sphalerite, 20 to 30 metres to the west, assayed anomalous concentrations of copper, bismuth, nickel, tin, tungsten and up to 4.55 per cent zinc (Assessment Report 34329).
In 2012, diamond drilling of the main zone yielded up to 0.76 per cent zinc over 13 metres, including a 2.16 metre section that assayed 2.66 per cent zinc (Hole TLDD-12-04; Press Release, Cullen Resources Ltd., November 9, 2012). Sampling of the gossan to the south east yielded up to 2.25 per cent zinc (Assessment Report 34329).
In 2014, rock sampling of trenches yielded up to 18.87 per cent zinc (Sample 14TR015b; Assessment Report 35415).
During 2011 through 2015, Cullen Resources Ltd., in conjunction with RIT Minerals, completed programs of biogeochemical and geochemical (rock, silt and soil) sampling, geological mapping, minor trenching, combined electromagnetic and magnetic airborne and ground geophysical surveys and six diamond drill holes, totalling 463 metres, on the area as the TL claims.
