The Dan showing is located at 1158 metres elevation on a small ridge on the east side of Budy Creek. The showing is 2 kilometres southeast of the Ket 28 prospect (082ESW210) and 6 kilometres east-southeast of Bridesville.

The ground hosting the Dan showing was staked as the Rock Group claims in 1986 by D. Hopper and S. Wirth. The Old Nick prospect (082ESW055) was the first major nickel occurrence in the immediate area, discovered in 1955. Since this time numerous aggressive exploration programs have been carried out in the area by Newmont Mining Corp., Nickel Ridge Mines Ltd., Utica Mines Ltd. and more recently by Phoenix Gold Resources Ltd., Sway Resources Inc., Gold City Mining Corp. and Orion International Minerals Corp. The 1990 exploration program at the Dan showing was conducted by Crownex Resources Corp.

The oldest rocks in the vicinity of the Dan showing are a metavolcanic and metasedimentary sequence assigned to the Carboniferous to Permian Kobau and Anarchist groups. Amphibolite, greenstone, quartzite, chert, chlorite schist and minor marble comprise the Kobau Group and amphibolite, greenstone, quartz chlorite schist, quartz biotite schist and minor serpentinized peridotite comprise lithologies of the Anarchist Group. Penticton Group lithologies outcrop to the east while Middle Jurassic porphyritic granite, granodiorite and monzonite of the Nelson intrusions are found to the immediate north. Smaller plugs, dikes and sills of biotite granodiorite, quartz diorite and granite of Middle Jurassic to Cretaceous age intrude the Anarchist Group rocks.

The Dan showing is underlain by a sequence of nearly flat-lying metasediments of the Anarchist Group. The sequence dips gently to the northwest(?) and has been crosscut by several Cretaceous granitic dikes. Going upsection the Anarchist sequence consists of phyllite, argillite, limestone with interbedded argillite and chert, and pebble conglomerate with greenstone interbeds. Tight folding associated with northeast and north-trending faults have occurred throughout the metasedimentary sequence. Phyllitic and mylonitic fabrics, and brecciation occur adjacent to many the predominant faults.

During an exploration program in 1990, assay values returned from two rock geochemistry samples were anomalous in nickel. Sample 90CM-349-R yielded 1.355 per cent nickel and 0.052 per cent chromium (Assessment Report 21414). Sample 90CM-350-R, taken 75 metres to the north-northwest also yielded 1.380 per cent nickel and 0.048 per cent chromium (Assessment Report 21414). Both samples were hosted in serpentinite. Minor magnesite skarn and barite lenses are reported on the Dana Group hosting the Dan showing. No description of the mineralogy or significant assay results have been reported for the skarns despite the discovery of the Buckhorn Mountain skarn system to the south.
