The Sweetsbridge showing is located 8 kilometres southeast of Falkland, on the north slope of the Salmon River valley.

In this area, sedimentary and volcanic rocks of the Upper Triassic to Lower Jurassic Nicola Group are in fault contact to the north with Cambrian-Ordovician volcanic (Tsalkom Formation) and sedimentary (Sicamous Formation) rocks. To the south the Nicola Group is in probable unconformable contact with Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group. Cretaceous granodiorite plugs of the Salmon Arm Intrusions intrude the Nicola, Sicamous and Tsalkom rocks. Outliers of Eocene Kamloops Group volcanic rocks are present in the area.

Sedimentary rocks of the Nicola Group host a gypsum deposit. White, brown and grey gypsum is exposed over a length of 180 metres, with a 12 metre thickness. It is similar to the Falkland deposit (082LNW001), 8 kilometres along strike to the northwest. The deposit may be a gypsum-rich facies of a Kuroko-type deposit.
