The Don W showing comprises a system of mineralized quartz veins that occur within the Permian to Upper Jurassic Sitlika volcanic unit about a kilometre southwest of Mount Bodine.

The veins are exposed, although not easily accessible, over a distance of about 200 metres in the south wall of the cirque basin, west of the mountain. Veins just below the ridge crest at the end of the system occur on either side of northeast-striking fault that defines a 300 metre apparent dextral offset of the contact between the volcanic and eastern clastic units. They range from a few centimetres to about a metre in width, and most dip at moderate to shallow angles to the southwest. Most of the thicker veins contain patches, up to several centimetres across, of limonite-altered pyrite, locally with chalcopyrite, malachite, and azurite. A sample of mineralized material from one of these thick veins contained 2.17 per cent copper, 0.38 gram per tonne gold and 1.8 grams per tonne silver (Fieldwork 1996, page 93). Veins farther west within the system are in part marked by gossan zones but were not examined.

In 2006, Amarc Resources Ltd. completed multiple geochemical surveys over the property containing the occurrence. Anomalous levels of copper, lead and zinc were detected in the soil sampling grids.

In 2008, Amarc Resources Ltd. conducted a soil sampling program on the Warren Grid, which covers the occurrence. Anomalous zinc, copper, lead, and silver values were observed; however, no specific samples were noted.

In 2009, Amarc Resources Ltd. completed four diamond drill holes, totalling 1419.7 metres on the Bodine-Warren property. None of the drilling was performed on the Don W occurrence. Broad intervals of low-grade zinc mineralization was observed. Follow up drilling was recommended.
