The governments of Chile and Argentina signed a protocol to facilitate the development of McEwen Mining Inc.'s Los Azules copper project in San Juan, Argentina.
The new protocol will facilitate project-related activities in the border zone between San Juan and Chile's Limari province.
TNR Gold Corp. holds a 0.36% royalty on the net smelter return of the entire project, the company said Nov. 30.
McEwen's preliminary economic assessment at Los Azules estimated a net present value of US$2.24 billion, using an 8% discount rate, and a 20.1% internal rate of return, with payback in 3.6 years and a 36-year mine life.
