The Tequila Sunset is a volcanogenic massive sulphide showing hosted in the middle volcanic division of the Tats group. It is located approximately five kilometres east-northeast of Tats Lake, and approximately 1.5 kilometres southeast of the Rainy Monday showing (114P 094). It was discovered in 1992 by British Columbia Geological Survey mapping crews.

The showing includes discrete, yellow and orange gossanous zones, 0.5 to 3 metres wide of tectonically admixed fine-grained sediment and foliated basalt (now chlorite schist) that occur within the hinge zone of a faulted, south-plunging anticline. A sequence of en echelon mineralized zones is exposed across about 20 metres and may extend over 100 metres of a cliff face south of the Ice Bridge glacier terminus. Malachite-stained chalcopyrite and pyrite occur as stratabound stringers within the pods. Chalcopyrite may comprise up to 15 per cent of the rock over intervals of less that 0.2 metres. Assay samples returned up to 1.56 per cent copper and 0.22 per cent zinc (Fieldwork 1992, page 22).

Controls on the distribution of the sulphides appear to be predominantly structural. This showing is similar in style to the Rainy Monday and the anticline is on trend with the Rainy Monday showing. Extents of the mineralization both above and below the immediate discovery zone are untested.
