The Home X occurrence is situated east of Spider Peak near the headwaters of Siwash Creek, approximately 500 metres northwest of the Pipestem mine (092HNW011). The area is underlain by grey to black, locally organic-rich, pyritic, slaty argillite intercallated with well-bedded siltstone, all assigned to the Early and Middle Jurassic Ladner Group. A number of northwest striking bands of medium to very coarse-grained, tuffaceous, fossiliferous wacke also occur within the sequence. The bands vary from 5 to 45 metres thick and are the principal host to gold mineralization at the Pipestem mine.

To the south, these sedimentary rocks have been intruded by narrow sills and dykes up to 4 metres thick. Several porphyritic felsic sills, similar to those associated with gold occurrences in the Siwash Creek area (092HNW004, 005, 015-017), host thin quartz veins with pyrite.

Approximately 600 metres northwest of the Pipestem mine, the collapsed portals of one, or possibly two adits and a small dump are the only evidence of previous development in the area. Here, black, poorly to moderately bedded slaty argillite is cut by irregular quartz veins up to 10 centimetres wide. The veins contain sparse pyrite and trace amounts of arsenopyrite concentrated in fractures that both cross the veins and parallel the vein/sediment contact. The dump also contains large fragments of quartz-veined argillite.

A rock sample taken in 1982 near the the Home X adit assayed 1.9 grams per tonne gold and 0.118 per cent arsenic (Assessment Report 11158, Figure 9).
