International Tower Hill Mines Ltd. (TSX: ITH; NYSE MKT: THM)is an advanced exploration stage company focused on the development of its 100% interest in the Livengood Gold Project located 70 miles northwest of Fairbanks, Alaska.
The Company on April 10, 2017 filed a NI 43 101 (the “April 2017 Pre-Feasibility Study”) on an optimized configuration for its Livengood Gold Project (the “Project”) located near Fairbanks, Alaska. The engineering optimization studies incorporated in the PFS evaluated several scenarios, ultimately selecting a project that will process 52,600 tons per day and produce 6.8 million ounces of gold over 23 years. This improved configuration has reduced the capital costs (“CAPEX”) by 34% or $950 million to $1.84 billion and the process operating cost (“process OPEX”) by 28% or $2.97 per ton to $7.48 per ton. All-in sustaining costs (AISC) are $976 per ounce and All-in Costs (AIC) are $1,247 per ounce. All as compared to the 100,000 tons per day project evaluated in the September 2013 Feasibility Study. All dollar figures are stated in US Dollars.
Pre-Feasibility Study Overview
The Project configuration evaluated in the PFS remains a conventional, owner-operated surface mine that will utilize large-scale mining equipment in a blast/load/haul operation. Mill feed would be processed in a 52,600 tons per day comminution circuit consisting of primary and secondary crushing, wet grinding in a single semi-autogenous (SAG) mill and single ball mill followed by a gravity gold circuit and a conventional carbon in leach (CIL) circuit.
