Project Geology

The property geology is dominated by rocks of the Early Jurassic Texas Creek Intrusive Suite which are interpreted as coeval intrusive equivalents to extrusive Hazelton Group volcanics which host significant mineral occurrences in the Golden Triangle. This synvolcanic intrusive is possibly related to the feeder intrusive to the proximal Premier and Big Missouri epithermal deposits.

The Top Prospect which is located near the tip of Mineral Hill is reported to consist of disseminated and semi-massive pyrite, sphalerite, and tetrahedrite, with a quartz-sulphide vein present. The mineralized zone was exposed by historic trenches for a length of 116 meters hosted in the Hazelton volcanics. It is probable that this deposit is Jurassic in age. The Jurassic Premier and Big Missouri Mines contain gold-silver and base metal-bearing silicified zones with disseminated to massive pyrite, galena, sphalerite, and tetrahedrite. The zones are marked by ill-defined hanging walls and footwalls and are hosted in Hazelton andesite. This is generally like the more sparsely mineralized gold-silver base metal Jurassic occurrences. Similarities to the Premier Mine (over 1.8 million ounces gold produced) and the Big Missouri Mine (64,270 ounces gold produced) encourage exploration of the known Jurassic gold-silver base metal zones and their vicinity for larger deposits. The geological target and exploration concept of the property is similar to the large intrusive-related and porphyry copper and gold deposits in the region such as Snowfield, Treaty, Kerr, and Mitchell, located adjacent to the high-grade Brucejack Gold Mine to the north.
