The Redcap anomaly is centred approximately 750 metres north of Idleback Lake and 20 kilometres east of Penticton. The Redcap was previously included as MINFILE showing 082ENW057.

The area is underlain by granodiorite of the Cretaceous-Tertiary Okanagan Batholith.

The anomaly consists of several copper and zinc soil anomalies discovered in 1969 by Cro-Mur Mines Ltd. A swampy area to the east drains the anomalous area, contains bog iron and is probably a gossan (Assessment Report 2173, Figure 5). In 1970, Cro-Mur Mines Ltd. embarked on a program which consisted of 7.2 kilometres of road construction, 140 metres of trenching and 4,600 square metres of stripping. No assessment reports were filed on this program.
