Several types of mineralization are found on the property including gold in quartz veins, copper‐cobalt in skarn deposits, copper‐platinum‐palladium in Karmutsen volcanics, and gold‐hosted epithermal quartz veins associated with shear zones. However, the main focus of current exploration efforts is the Brynnor iron deposit.
The deposit type on the property is magnetite skarn mineralization, in this case hosted in a roof pendant of metasomized Quatsino formation limestone and calcareous tuffs and Karmutsen formation andesite. The Brynnor deposit was formed by metasomatic alteration of carbonate rocks in the metamorphic halo of major batholiths. Magnetite has the highest concentration of iron at 63.7% of all the iron bearing minerals.
