The NATIVE SON showing is situated adjacent to Castle Creek, a tributary to Cadwallader Creek, approximately 700 metres southwest of Bralorne, B.C.
Mississippian to Jurassic Bridge River Complex (Group) metasediments and closely associated Upper Triassic Pioneer Formation (Cadwallader Group) mafic volcanics (greenstone) are tightly folded with east-west trending subvertical axial planes. Granites and diorites of the Permian Bralorne Igneous Complex and a narrow talc-altered serpentine belt (President Ultramafics correlative with the Permian and older Shulaps Ultramafic Complex) intrude the metasediments.
Irregular, 0.5-metre-wide quartz veins and lenses parallel the enclosing metasediments and contain albite, pyrrhotite and small amounts of stibnite, arsenopyrite and pyrite. The Native Son vein is reported to be exposed approximately 200 metres south of the adit. Samples were reported to assay up to 23.31 grams per tonne silver and traces of gold (National Mineral Inventory 092J15 Au15).
Native Sons Mines drove an adit on the west valley wall of Cadwallader Creek in 1933. In 1945, Pinebrayle Gold Mines acquired the Native Son workings and the Short O'Bacon prospect, approximately 1.5 kilometres to the northwest. Leitch Mines acquired an interest in Pinebrayle in 1946 and commenced a program of surface exploration including pits, trenches and open cuts. A short adit was driven on the north bank of Castle Creek, approximately 100 metres upstream from the Native Son adit. 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, resulting in the interpretation of 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).
