The Stan showing is located approximately 2 kilometres southwest of Summit Lake, and approximately 16 kilometres southeast of Nakusp.

Little is known about the occurrence other than a personal communication from George Addie describing amygdaloidal basalts with a little molybdenite on some joint surfaces (George Addie, personal communication, 1978).

The basalts probably belong to the Jurassic Elise Formation of the Rossland Group and are stated to occur near the contact with slates and limestone of the Triassic Slocan Group (George Addie, personal communication, 1978).
