The Miocene showing is located immediately west of the Horsefly river, covered now by the town of Horsefly. The 2 compartment shaft is approximately 1000 feet southwest of the old Wards' hydraulic pit. This is 137 metres deep in loose gravel and till. The shaft bottomed on Eocene siltstones and shales, and a decline was driven (southwest-west) along the "bedrock" surface.

The three compartment shaft is underneath the B.C. Telephone utility trailer across from the community hall. The shaft is 167 metres deep in unconsolidated till and gravel. A 152 metre drift was cut at the siltstone "bedrock" level. The gravel and boulder conglom- erate in contact with the "bedrock" is partially cemented, many metres thick.

The gold, or pay gravels, occur in the lower yellow, quartz pebble/cobble rich gravels. As well blue gravels (blue shales) at the contact of the gravels and siltstones carry gold. No assays or values are reported but were said "to pay well". By inference with similar deposits in the area, Ward's Horsefly and Hobson's Horsefly, a value of several cents per cubic yard (order of 0.001 ounce per yard) can be suggested.

No production is recorded for the site and all the workings are collapsed. This deposit is inferred as being within the old "Miocene Channel" that hosts the placer deposits in the Horsefly area.

"Data from the Cariboo mining district indicate that supergene leaching of gold dispersed within massive sulphides by Tertiary deep weathering followed by Cenozoic erosion is the most likely explanation for the occurrence of coarse gold nuggets in Quaternary sediments" (Exploration in British Columbia 1989, page 147).
