QuestEx Gold & Copper Ltd. announced that drilling conducted on their 100% owned Sofia property, located in British Columbia's ("BC") prolific Toodoggone mining district, has confirmed along-strike potential of the Quartz Lake gold ("Au") -silver ("Ag") epithermal vein system and expanded the footprint of the Sofia porphyry copper ("Cu")-Au system. QuestEx's 2021 exploration program on its 93 square kilometre ("km") Sofia property included 1,611 metres ("m") of diamond drilling, which targeted the Quartz Lake, low-sulphidation, epithermal vein system (five drill holes, 776 m), and related porphyry copper-gold systems (two drill holes, 835 m), as well as follow-up and infill soil sampling (406 samples). Highlights from the program include: Expansion of the 300 m long Quartz Lake Au-Ag vein system by an additional 55 m to the northwest, demonstrating multiple mineralized veins with down-dip continuity. Recognition of porphyry Cu-Au style mineralization at the Tranquillo target indicating an expansion to the footprint of the nearby Sofia porphyry target. New identification of a 1,000 by 800 m multi-element (Au-Cu-molybdenum ("Mo")) soil anomaly.
