The MOFFAT showing is located east of Moffat Creek, 2 kilometres west of Triplet Lake and 5 kilometres south-southwest of the village of Horsefly. Best access is from Horsefly via the 108 Road southwesterly to Gammarus Lake or via the Starlike Lake Road. The roads are good, all-weather gravel roads used primarily by local ranchers and the forest industry. Numerous tote and skid roads provide excellent secondary access.

A considerable area of south-central British Columbia is underlain by Miocene plateau basalt, largely confined to the area between the Pinchi-Fraser fault system to the east and the Yalakom fault system to the west. However, remnants of the plateau basalt occur in Quesnellia. One of these remnants outcrops in the Moffat Creek area and is known as the Moffat or Falls showing.

The majority of the showing area is covered with a heavy mantle of glacial till and glaciofluvial silt deposits. Bedrock exposed in Moffat Creek canyon consists of Lower Jurassic porphyritic (augite?) basalt of the Nicola Group. Younger Miocene flood basalts overlie the Jurassic volcanics.

Minor amounts of copper sulphide (chalcopyrite) and native copper occur within the plateau basalt. This showing is one of three copper occurrences recorded in the area, the others are the Red occurrence (093A 064) about 1.45 kilometres to the northwest, and the polymetallic Stope Baby zone in Moffat Creek canyon, 500 metres to the west-northwest.

The Stope Baby zone was discovered in 1999 and was drilled by Erin Ventures in 2000 (two holes totalling 346 metres), following an induced polarization/magnetic survey over an area of stockwork mineralization. The showing consists of an 8 metre wide, north trending shear zone consisting of quartz-carbonate gangue with accumulations of massive sphalerite, chalcopyrite and galena. An aggregate sample across the zone returned 0.64 per cent copper, 1.80 per cent lead, 21.01 per cent zinc, 103.54 grams per tonne silver and 2.4 grams per tonne gold. One of the holes intersected a 0.8 metre section of semi-massive sphalerite enclosing blebs of galena and chalcopyrite within a grey green carbonate zone at 119.9 metres downhole. The section returned assays of 0.13 per cent copper, 0.10 per cent lead, 3.57 per cent zinc, 9.1 grams per tonne silver and 0.42 gram per tonne gold (Assessment Report 26377).

Tenure holders H. Wahl and J. Brown-John conducted intermittent soil surveys of various types over zones throughout the Moffat area during the period 2008 through 2016.
