All mineralized zones on the Property are hosted within Stuhini Group volcanic and volcaniclastic strata, as well as alkaline stocks and dykes which intrude into the volcanic package and show a clear spatial association with the mineralized zones. Geological studies have suggested the intrusions were the likely source of hydrothermal fluids and gold-silver-lead-zinc mineralization on the Property.
The Upper Alteration Zone is adjacent to an important unconformable contact between the Upper Triassic Stuhini Group and Lower Jurassic Hazelton Group. The unconformity, referred to as the “red line” was recently recognized by Joanne Nelson and Jeff Kyba of the BC Geological Survey (BCGS) as playing a major role in the emplacement of all significant mineral deposits within the Golden Triangle district including Brucejack, KSM, Schaft Creek, Galore Creek, Spectrum, Saddle (GT Gold) and Red Chris. The Stuhini-Hazelton transition cuts the southwest portion of the Property as indicated by the thick red line in the Hank Project Regional Geology figure.
A feldspar megacrystic stock, known as the Bald Bluff Porphyry intrudes along its northern edge and was interpreted by Kaip (1997) as the source of the mineralizing fluids at Hank. 2017 drilling in the Lower Alteration Zone intersected intrusive rocks similar in texture and composition to the Bald Bluff Porphyry, which have a clear spatial association with high grade gold-silver mineralization. 2018 work will be focused on mapping the intrusive rocks on the Property and refining the current drill targets.
