The SAND showing is located beside Copperkettle Creek, approximately 8 kilometres north of Christian Valley.

The showing occurs in Eocene Marron Formation (Penticton Group) andesite and minor welded tuff.

In 1970, Mitsui Mining Co. Ltd. carried out a 3-hole diamond- drill program to test for basal uranium mineralization under the Marron Formation volcanics. They were unable to penetrate the volcanic cover, despite drilling to a 214 metre depth in hole "C", and subsequently abandoned the program. They did, however, intersect minor clay and sulphide mineralization in diamond-drill hole "A". This mineralization consisted of calcite veinlets, and narrow clay-alteration zones containing disseminated pyrite, chalcopyrite and, in one spot, galena. All sulphide mineralization was intersected within 60 metres of the surface. No assays were made of the mineralization.

In 1979, Veronex Resources Ltd. carried out geological mapping and 110 metres of trenching in 6 trenches near the junction of Copperkettle and Sandrift Creeks, approximately 450 metres north of the showing. The results of this program were not recorded.
