Pacific Ridge Exploration Ltd.: Pacific Ridge Announces Redton Drill Results and Provides Exploration Update Vancouver, British Columbia--(Newsfile Corp. - December 11, 2020) - Pacific Ridge Exploration Ltd. (TSXV: PEX) ("Pacific Ridge" or the "Company") reports on results of a single diamond drill hole, RTN-20-01, located 2.5km north of the Kwanika Central Zone at the road accessible Redton North target. The drill hole tested a 550 m by 250 m magnetic and IP chargeability anomaly and coincident copper-molybdenum soil anomaly located 2.5 km north of Serengeti Resources Inc.'s ("Serengeti") Kwanika Central Zone deposit 1. The drill hole encountered a magnetite-bearing mafic intrusive with a minor amount of quartz, potassium feldspar, chlorite, calcite, gypsum and epidote veining, moderate to strong chlorite alteration and local serpentinization. No significant copper or gold assays were encountered. The ubiquitous presence of magnetite as well as strong magnetic susceptibility values (average of 44.9 SI and maximum of 505 SI) in the drill hole explain the magnetic anomaly. The source of the chargeability and Cu-Mo anomaly remains unexplained.
