The Putnam showing is located south of Putnam Creek, about 15 kilometres north of Lumby.
In 1984, a regional reconnaissance geochemical survey was carried out by Brican Resources. In 1985, detailed geological and geochemical evaluations were conducted.
The area is underlain by sedimentary and volcanic rocks of the Upper Triassic to Lower Jurassic Nicola Group. These comprise banded quartzite/gneiss, argillite, phyllite with interbedded siltstone and quartzite, augite andesite, greenstone which are intruded by granodiorite and aplite dikes.
A main fault zone trends northwest across the northeastern corner of the property. Augite andesite within the fault zone has been sheared, bleached and pyritized.
Quartz and quartz calcite veins are associated with other faults and fault zones on the property. A vein in the southwestern corner of the property contains minor amounts of galena. Rock samples from the property assayed low in gold and silver (Assessment Report 13311).
