The David (Bethex) occurrence is located on the north side of the western arm of Jim Kelly Creek, approximately 6.2 kilometres northeast of its junction with the Similkameen River.

The area is underlain by sediments of the Lower to Upper Cretaceous Pasayten Group, which are composed of altered, fractured and fissured sandstone, conglomerate and pelite. These are intruded by foliated diorite of the late Jurassic to early Cretaceous Eagle Plutonic Complex. To the north, the upper Oligocene–lower Miocene Coquihalla Formation, composed of basalt, rhyolite, tuff and agglomerate, caps Coquihalla Mountain.

Locally, three zones of mineralization have been identified: the Main (B), Northwest (A) and East (C) zones. Mineralization consists primarily of disseminated and fracture-filling pyrite with lesser amounts of chalcopyrite and pyrrhotite, hosted by a chloritized diorite to hornblendite. Quartz stringers and veinlets are also reported to host mineralization. Nickel values are reported in association with the Main zone, while the Northwest zone contains scattered sphalerite mineralization associated with calcite stringers.

The Main zone covers an area of 240 by 60 metres; the Northwest zone, located approximately 800 metres to the northwest, is exposed over 360 by 120 metres. The East zone, located approximately 400 metres northeast, consists of an approximately 450-metre long shear and trends north 60 degrees west.

In 1966, surface sampling of the Main zone yielded up to 2.4 grams per tonne silver, 0.20 per cent copper and 0.31 per cent nickel from nine samples over 28.8 metres; including 5.5 grams per tonne silver and 0.25 per cent copper from three samples over 9 metres and up to 0.48 per cent copper from single samples (Property File - A.G. Hodgson [1967-05-02]: Preliminary Report on Kelly Creek Property).

Diamond drilling, also performed in 1966, yielded intercepts of up to 0.56 per cent copper over 6.0 metres in drill hole no. 2, 0.25 per cent copper over 9.0 metres in drill hole no. 3 and 0.12 per cent copper over 18 metres in drill hole no. 1, all from the Northwest zone (Property File - A.G. Hodgson [1967-05-02]: Preliminary Report on Kelly Creek Property). The Main showing yielded up to 0.09 per cent copper over 9.0 metres from drill hole no. 5 (Property File - A.G. Hodgson [1967-05-02]: Preliminary Report on Kelly Creek Property).

In 1967, nine samples, taken over an area of 210 by 45 metres, yielded from 0.05 to 0.77 per cent copper and 0.05 to 0.24 per cent nickel (Property File - R.J. Darney [1967-10-11]: Examination Report - Kelly Creek Project).

The area has been explored since the late 1890’s. In 1909, copper-gold ore was reportedly removed by James Kelly but the exact location of this is unknown. In 1914, the John Bull, Spokane, Vancouver, Marsellaise, Superior and Gold Mountain groups were explored. In 1926, exploration was done on the Silver Bell and Belmont claims, thought to be the same vein as previously worked by James Kelly. In 1937, the Evening Star group was worked by W.B. Marks.

In 1965 and 1966, Bethex Explorations completed 32 trenches, totalling 5400 metres, and five diamond drill holes, totalling 850 metres, on an area of possible porphyry copper mineralization located on the P.R. and David claims. The following year, Atlas Explorations prospected and sampled the area. During 1982 through 1985, Minequest Exploration completed programs of prospecting and soil sampling the area as the Aura claims. In 1989, T.M. Parsons prospected and sampled the area as the Fortune and Great Scott claims.
