Veins in the sediments contain little gold except where they cut across the beds at low angles. Unless the wall rock is mineralized, gold is seldom found there. The indicators of the presence of gold are, there fore: (1) fine, light, granular pyrite, (2) fine aggregates of arsenopyrite, (3) massive or disseminated stibnite, (4) mineralized relict structures in quartz, (5) well-developed quartz veins, (6) carbon wisps in the quartz, (7) ribbon structures in the quartz, (8) carbonitization of the wall rock, and (9) serpentinization of the wall rock.

In the slates, sliding is much more evident; original openings along the contacts between sediments and lavas made room for the easy entry of the older intrusions (dia bases), while those along the contacts between the argillaceous graywackes and the quartzites were available to the introduction of the epidolerites. The mineralized lodes (or veins) are associated with five major, northsouth fractures, and these breaks are known as (from west to east): (1) Motor Centre, (2) Footwall B, (3) Cam Spur, (4) New Cam Spur, and (5) Cam Hanging Wall.
