Upper Triassic and Lower Jurassic rocks in the Treaty Creek property and surrounding areas are the host rocks of important mineral deposits (e.g., Kerr, Sulphurets, Mitchel (KSM), Snowfield, Bruceside), ranging from an epithermal setting to a porphyry setting, some of them exceptionally large and rich, and also hosting the potential for gold-rich VMS mineralization (e.g. Eskay Creek deposit).
There is a highly visible trend, marked by the surface alteration (oxidation) of exposed sulphide-rich mineralized rocks that produce what are called “gossans” in geologic terms. These gossans appear as orange-brownish zones that contrast with the surrounding rocks and are evidence of the development of large hydrothermal mineralizing systems. This trend of gossans and mineralized zones runs approximately 10km through the Kerr, Sulphurets, Mitchel, Snowfield, Iron Cap deposits and through the Treaty Creek property, where the same style of gold-silver-molybdenum mineralization has been found.
Within the Treaty Creek property, ten different zones have exposed mineralization and associated surface alteration. Porphyry, epithermal, and VMS systems have been identified on the property.
