Gold mineralization has been investigated at three localities on the West Cedartree Gold Project. The McLennan Gold Zone, the Angel Hill Gold Zone and the Dogpaw Lake Gold Zone form three similar types of mineralization. All three gold zones share an association with intense carbonatization and silicification along distinct structures or lithological contacts.
“The McLennan Gold Zone (MGZ) has been historically explored by surface trenching and pitting as well as shallow drilling. The zone has not been intensively explored by Houston. However, gold values from minor sampling appeared to duplicate historic work on the zone. Gold occurs within a 3.0-5.0m wide carbonatized zone contained within mafic metavolcanic massive flows of the Snake Bay Formation at the western contact of the basal Kagaki Sill. Gold is associated with sulphides, brecciation, stringer sulphide veining, quartz–carbonate veining and silicification.
The Angel Hill Gold Zone on the McLennan Property has a surficial expression with 130m of strike. Gold mineralization occurs within an 8-20m wide alteration and shear zone that follows the contact between an ultramafic basal portion and the gabbroic upper portion of a large differentiated gabbro sill. The alteration consists of serpentinization, carbonatization, fuchsitization and silicification that have affected mainly the upper portions of the ultramafic unit. Most of the best gold mineralization occurs within highly fractured structurally complex central core sections of the zone and has an association with quartz veins, silicification, and fuchsite alteration. The gold itself within the Angel Hill Gold Zone does occur, at least in part, as coarse visible grains and specks up to 0.5 millimetres in size. The gold is relatively evenly distributed in the host rock occurring as coarse flakes (> 150 mesh), fine flakes (<150 mesh), and/or in combination with other metallic minerals including pyrite, chalcopyrite, arsenopyrite, galena, or molybdenite” (Cutting, 2005).
