The Gringo prospect is located on the northern slopes of the divide between Stenson Creek and McGuigan Creek. The former Lucky Jim mine (082KSW023) is located 1.5 kilometres to the northwest. Kaslo, British Columbia lies some 27 kilometres to the east-southeast.

Lithologies underlying and surrounding the Gringo prospect include limestone and slate of the Triassic Slocan Group. A thick limestone bed on the Gringo claim is an extension of limestone intimately associated with orebodies at the former Lucky Jim mine.

Workings on the Gringo claim group consist of a shaft and opencuts on a narrow vein or veins composed of quartz carrying galena.
