The Brown (Broom) occurrence is located at an elevation of approximately 1260 metres adjacent to Broom Creek.

Regionally, the area lies near the southeastern border of the multiphase Upper Triassic to Lower Jurassic Guichon Creek Batholith, which intrudes Upper Triassic Nicola Group volcanic rocks. The area is underlain by both Guichon and Chataway varieties of the Highland Valley phase of the batholith. The Guichon variety rocks are fine- to medium-grained quartz monzodiorites to granodiorites; the younger Chataway variety are medium- to coarse-grained granodiorite.

Locally, a north-trending zone of azurite-malachite mineralization in a quartz monzonite and granodiorite is reported.

In 2012, a sample (HS-2) assayed 0.911 per cent copper, whereas another sample (HS-1) taken several hundred metres to the south yielded 0.166 per cent copper (Assessment Report 34157).

In 2013, a rock sample (Rat13-R08) of medium-grained granodiorite (Highland Valley phase?) hosting carbonate-quartz veins with epidote, chlorite and malachite, located approximately 1 kilometre east of the occurrence, yielded 0.275 per cent copper (Assessment Report 34641).

Later work (2018) identified a west-trending and south-dipping, 0.5- to 1.0-metre wide fault and fracture zone hosting a thin anastomosing shear zone with semi-massive chalcocite-bornite lenses associated with quartz-sericite-carbonate alteration. Cross-cutting fractures in Chataway phase granodiorite, up to 7 metres away from the fracture zone, host thin veinlets of bornite, chalcocite and malachite. This zone is located approximately 200 metres west-southwest of the previous zone of mineralization.

In 2018, a select grab sample from the shear yielded 15.4 per cent copper, 33.7 grams per tonne silver and 0.158 gram per tonne gold (Assessment Report 38172).
