Capsule Geology

The Gossan occurrence is located on the south end of the Cambria Icefield approximately 20 kilometres southeast of Stewart, B.C.

The Gossan Zone covers a northwest-southeast trending mineralized shear zone with several historic high-grade gold grab samples collected along its extent as well as several high-grade Au-in-soil results located downslope of the surface showing. Back-pack drilling was conducted in 2018 to test the Gossan occurrence, which is observed as quartz-sericite-pyrite altered volcanic rock with abundant disseminated pyrite.

In 2018 an airborne magnetometer survey was flown over Tenajon/Sunvest Minerals' Clone property, including the Gossan showing. The Gossan showing is located at the northern portion of a nine kilometre long magnetic high anomaly that trends northeast-southwest through the center of the Property. This magnetic anomaly maybe associated with the strong multi-element results. Back-pack drilling at the Gossan Zone returned elevated to strong values for gold, molybdenum, silver and copper. Gold results were strong with six of the eight core samples assaying greater than 200 parts per billion gold and molybdenum results were very strong with seven out of the eight samples assaying greater than 100 parts per million Mo and half the samples assaying greater than 400 parts per million Mo with the highest sample assaying 708.35 parts per million Mo. Silver results were elevated with six of the eight core samples assaying greater than 2.0 grams per tonne Ag (Assessment Report 38189).

In 2019 Ridgeline Exploration Services Inc. designed a 149 metre drill hole at the Gossan to drill test the down dip extension of surficial zones. Drill Hole SCL-19-05 intersected a lapilli tuff unit throughout the entire hole. Locally there are large centimetre to decimetre-scale gabbroic clasts. There is weak to moderate epidote and chlorite alteration throughout the hole, with select gabbroic clasts displaying moderate to strong chlorite alteration. Mineralization is dominated by weak blebby to disseminated pyrite + chalcopyrite mineralization concentrated within zones of strong epidote alteration. Drilling at the Gossan zone was unsuccessful in intersecting any mineralization or significant alteration downdip of surface zones.
