The property is underlain by Upper Triassic Stuhini rocks and Lower Jurassic Hazelton volcanic and sedimentary rocks that have been intruded by an early Jurassic-aged hornblende-feldspar porphyry, similar to and potentially comagmatic with the Goldslide Intrusive suite at Red Mountain.
The tight oil produced from the Upper Triassic Chang 7 lacustrine sandstone accounts for 15% of the total oil and gas resources in the Ordos Basin of China and is considered an essential resource for future exploration (Zouet al.,2013; Asghar et al., 2018).The commercial production of tight oil requires significant hydraulic fracturing, similarly to production in shale gas.
