Location and accuracy The Lillian prospect is near the head of Lillian Creek about 3/4 of a mile south of Livengood and 3/4 of a mile northwest of Money Knob. It is about 0.5 mile northeast of the center of section 22, T. 8 N., R. 5 W.

Geologic setting

Geologic description

This small old prospect is now part of the large International Tower Hills, Livengood prospect (LD202) that has been intensely studied and drilled since 2006. The Lillian prospect has largely now lost its identity and the data in this record has been integrated into the Livengood record. This record has not been updated since the exploration stated on the Livengood prospect and the pre-Livengood information here is retained in its original form for historical reference.
Narrow auriferous arsenopyrite-quartz-scorodite veins occur in and near a limonite-stained dike in altered and contorted graywacke-argillite country rock; samples contained from 0.5 to 48 ppm Au (Foster, 1968). Joesting (1942, ATDM Pamph. 1), reported a mineralized zone in a cut bank that contains stibnite and traces of cinnabar and gold.
