Entrée Resources Ltd. announce the results of an updated Feasibility Study that was completed on its interest in the Entrée/Oyu Tolgoi joint venture property. Entrée has a 20% participating interest in the joint venture with Oyu Tolgoi LLC holding the remaining 80% interest. The Entrée/Oyu Tolgoi JV Property comprises a significant portion of the long-life, high-grade Oyu Tolgoi copper-gold mining project in Mongolia. The updated Feasibility Study only reports on mineral resources and reserves attributable to the Entrée/Oyu Tolgoi JV. The updated Feasibility Study discusses two development scenarios, an updated reserve case and a Life-of-Mine Preliminary Economic Assessment. The 2018 Reserve Case is based only on mineral reserves attributable to the Entrée/Oyu Tolgoi JV from the first lift of the Hugo North Extension underground block cave. Lift 1 of Hugo North (including Hugo North Extension) is currently in development by project operator Rio Tinto, with first development production from Hugo North Extension expected in 2021. When completed, Oyu Tolgoi will become the world's third large copper mine.
