Understanding the geology leads to better and more cost effective exploration programs. Geological models that are derived from field observations can be used to drive exploration programs, and geophysics and geochemistry can be utilized to delineate future exploration targets. In 2017, Taranis completed K-Ar age-dating on three "Green Tuff" rocks from the property that are believed to be related to the introduction of hydorthermal activity that led to the formation of the ore deposits. 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 'Green Tuff' unit found at Thor is Carboniferous in age.
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
