had a rake either to north or south, the two crosscuts may not have explored the vein-zone sufficiently thoroughly. Assays of selected pyrite samples from the dump (see Table VII) indicate that the vein pyrite may carry a high gold content. Despite this, one of the less favourable aspects is that the observed pyrite content of the veins is generally very low.

No information is available on when, or by whom, the surface work on this vein was done. It is claimed that 20 tons of ore was shipped to the reduction-works near Barkerville, but no records of it are available. The vein is exposed by surface trenches and drifting for a length of about 190 feet. Trenches on strike to the south-west and a bulldozed trench to the north-east failed to find extensions of the vein in those directions. The main working consists of an open-cut driven in a north-westerly direction for 80 feet, at which point the vein 46
