The Hercules group of claims included the Crown-granted Glacier, Martha Ellen, Cornelius, Empire, and Leckie Fraction, which were located north of the Big Missouri property. 

Surface pits, trenches, and underground workings are readily accessible from the Granduc road which crosses the old property limits.
The surface mineralization now visible in the cuts and trenches consists of irregular quartz stockworks and sulphide pods and lenses filling irregular fractures in northwesterly trending shear zones developed in variably schistose green volcanic conglomerates. 

Pyritized and silicified country rocks on the property contain scattered fine-grained pyrite, galena, and chalcopyrite with erratic gold-silver values.
