The Unicorn showing is located about 1.6 kilometres above Ferry Creek, 27 kilometres east of Lumby.

The showing was examined by the District Geologist in 1976. No other work is recorded.

The area is underlain by sedimentary and volcanic rocks of the Upper Triassic to Lower Jurassic Nicola Group. These comprise graphite-bearing calcareous argillite and limestone.

The flat-lying, white, quartz vein is about 15 metres in length, about 3 metres in width and is up to 20 centimetres thick. Fine grained, cubic galena and marcasite occur in a dendritic fashion in the centre of the vein. The quartz appears to have grown from the wall of the vein; no cavities were seen. Sulphides compose about 8 per cent of the quartz vein material.
