The SHORT O'BACON prospect is situated adjacent to Carl Creek, a tributary to the lower reaches of the Hurley River, approximately 1.7 kilometres west of Bralorne, B.C.

The main Short O'Bacon showing is hosted in greenstone, probably of the Upper Triassic Pioneer Formation (Cadwallader Group) near its contact with serpentinite of the President Ultramafic (correlative with the Permian and older Shulaps Ultramafic Complex). Mississippian to Jurassic Bridge River Complex (Group) cherts and argillites and Upper Triassic Noel Formation (Cadwallader Group) argillites are exposed to the east and south.

The vein is in a shear zone striking northwest and dipping steeply, containing quartz and sheared greenstone with quartz stringers. The vein has been followed for 150 metres and a possible extension may parallel the serpentine belt along Carl Creek. A possible convergence with the BRJ 1 vein (092JNE136) located to the southwest has been suggested.

Directly east of the Short O'Bacon adit is another vein on the east bank of Carl Creek in a wide shear zone, also in Pioneer greenstone near the serpentinite contact. The rock is talcose and highly sheared and contains abundant mariposite and cubic pyrite. A 30-centimetre quartz vein is sparingly mineralized with pyrite and a little gold. About 200 metres west of the Short O'Bacon vein is another greenstone-hosted vein-shear striking southeast and dipping steeply west. Sericite, chlorite and iron sulphides occur in approximately 1.2 metres of quartz. Surficial gold values are reported to be low.

In 1945, Pinebrayle Gold Mines acquired the Short O'Bacon prospect and the Native Son workings, approximately 1.5 kilometres to the southeast. Leitch Mines acquired an interest in Pinebrayle in 1946 and commenced a program of surface exploration including pits, trenches and open cuts. Further prospecting, the driving of a short adit and drilling of two holes was accomplished between 1948 and 1951.

In 1988, Levon Resources flew the area as part of a regional airborne magnetometer and VLF-EM survey, which interpreted two strong conductors and one medium strength conductor in the area.

In 2018, Wild West Gold Corp. produced a report on their Bralorne South property, including the Short O'Bacon, Native Son and the BR Jewel occurrences. The report included results from the previous airborne geophysics, government regional stream sediment sampling and satellite imagery interpretation (Assessment Report 37557). Programs of drone magnetometer surveys and MMI soil sampling followed in 2020 and 2022. Three areas of interest with unique magnetic signatures and coincident MMI gold soil anomalies were detected in these programs (Assessment Reports 39338, 41306).
