The I.X.L. and Condor claims were located near Castledale; very little work had been done, but according to reports there is a strong surface showing of low-grade ore (Minister of Mines Annual Report 1917, page F144).

The geology of the area is inferred from Geological Survey of Canada Map 1501A and consists of grey, finely laminated, partly calcareous slate with thin interbeds of limestone locally, of the Upper Cambrian Canyon Creek Formation. Galena and sphalerite are inferred from the assays of a sample of the ore which analysed from 17 to 34 grams per tonne silver, 4 to 6 per cent lead and 3 to 37 per cent zinc (Minister of Mines Annual Report 1917, page F144).
