The Molly showing occurs in an area underlain by the Early Jurassic Limpoke pluton (Texas Creek Plutonic Suite), a two-phase stock with a biotite hornblende quartz monzonite outer phase and medium-grained hornblende monozodiorite inner phase. Leucocratic potassium feldspar megacrystic syenite dikes intrude the eastern and western borders of the pluton and surrounding Upper Triassic Stuhini Group sedimentary and volcanic country rock.

An 8 to 15-centimetre-wide quartz-carbonate vein with pyrite and molybdenum graded 0.096 per cent molybdenum, 0.24 gram per tonne gold and 2.6 grams per tonne silver (Sample 446922, Assessment Report 19439). At the same given location as sample 446922, a 2 to 10-centimetre quartz-carbonate vein with massive pyrite ran 0.93 gram per tonne gold and 16.4 grams per tonne silver (Sample 446921, Assessment Report 19439). A geology map from Assessment Report 19439 indicates that the sample area consists of granodiorite, quartz diorite, minor diorite and/or minor syenite.

Another zone of mineralization, referred to as the Copper Bowl zone, is located approximately 300 metres south-southeast of the Molly occurrence. In 2019, five consecutive 50-metre reconnaissance rock chip samples from the Copper Bowl zone returned from 0.23 to 8.53 grams per tonne gold (Equity Exploration Consultants Ltd.
