Argillaceous quartzite and calcareous quartzite of the Middle Proterozoic Dutch Creek Formation (Purcell Supergroup) are in contact with quartz monzonite of the Cretaceous Horsethief Batholith.

On the Stan 6 claim, it was noted that small amounts of molybdenite occur in an aplite dike that cuts Dutch Creek rocks. The intrusive contact is to the immediate south.

The eastern portion of the Stan 6 claims, that encompasses the Stan 6 occurrence, had been previously staked as the Ice claim in the early 1970s. See 082KNE002 (S) for a discussion of that work which occurred more to the southeast. Cominco Ltd. staked the Stan 1 to 6 claims in 1976 and followed up in 1977 by taking 55 silt, 52 water and 13 rock samples. In 1978, Cominco conducted a geological mapping survey and collected 154 soil and 8 silt samples for analysis.
