The Eureka Creek deposit is located on Eureka Creek, a tributary of Barnes Creek, about 50 kilometres southeast of Lumby.
The bedrock in the area consists of sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group.
This placer deposit is indicated as #355 on Geological Survey of Canada Open File Map 637. From 1931-1945, a total of 870 grams of gold is recorded as production from Eureka Creek (Bulletin 28, page 14).
In 1983, heavy sediment sampling on the Zag claims resulted in several anomalous gold samples from tributaries of Eureka Creek. No anomalous samples came from Eureka Creek. No other information is available.
