Understanding the geology leads to better and more cost effective exploration programs. Geological models that are derived from the geology can be used to drive exploration programs, and geophysics and geochemistry can be utilized to delineate targets. In 2017, Taranis completed K-Ar age-dating on three tuffaceous ("Green Tuff") volcanic rocks from the property. These gave the following age dates:
The sample from the Broadview was not used as it was altered and not optimal for K-Ar age dating. The results show that the Volcaniclastic unit found at Thor is Carboniferous in age and based on mapping completed by provincial surveys, it correlated with the Jowett Volcanics. The Broadview Formation lies directly on top of the Jowett Formation at Thor, and immediately underlying this is the Sharon Creek phyllite (Smith and Gerrels, 1990).
This sequence is identical to what is found at Thor, and the mine names correlate as shown below:
Upper Series = Broadview Formatiom
Green Tuff = Hydrothermal Alteration (Ammonium Illite-Altered Rocks)
Lower Series = Sharon Creek Phyllite
