The Peoria prospect is located on the northern slopes of the divide between Stenson Creek and McGuigan Creek. The former Lucky Jim mine (082KSW023) is located 2.5 kilometres to the northwest. Kaslo, British Columbia lies some 27 kilometres to the east-southeast.

Lithologies underlying and surrounding the Peoria prospect include limestone and slate of the Triassic Slocan Group. A thick limestone bed on the Snowflake claim is thought to be correlative with limestone intimately associated with orebodies at the former Lucky Jim mine.

Workings on the Peoria claim group consist of a 16-metre shaft on the Snowflake claim, two short adits on the Harriet claim and numerous opencuts and shallow trenches on these and the other claims.

Some small fissure veins were exposed in workings on the Peoria claim group. These fissure veins strike northeast, intersecting limestone and slate. Veins were mainly quartz with argentiferous galena.
