- Phase I, which is a standalone operation requiring only state and local permits for an extended 20-year mine life, has an after-tax net present value (8%) of $1.1 billion and generates a 19% internal rate of return at a copper price of $3.75 per pound.2345234Mineral Reserve and Resource Estimates(millions)1234(%)(%)12(%)(%)Vice President, Investor Relations

[email protected]A detailed cash flow model containing annual production and cost information is shown below. Overall assumptions for commodity prices, marketing parameters, operating costs and capital costs are also provided.2Phase I is expected to consist of four open pits and all associated infrastructure within a footprint that requires only state and local permits for 20 years of operation.
Phase I includes a 60,000 ton per day conventional concentrator with an expansion in year 5 to include a concentrate leach facility to produce copper cathode onsite.
The project assumes conventional tailings deposition in three tailings storage facilities located on land requiring only state and local permits for Phase I.
One of the many benefits of producing copper cathode on site using the concentrate leach facility as presented in the PFS is that the cathode is likely to be sold entirely to the domestic U.S. market, thereby reducing total GHG emissions by an estimated 14% compared to an operation that solely produces copper concentrate (flotation only). Constructing the full 100% capacity concentrate leach facility at inception would reduce total GHG emissions by 25%.
The mineral resource estimates were prepared using a 0.1% copper cut-off and include four deposits: Peach-Elgin, West, Broadtop Butte and East.iiiiiihttps://www.globenewswire.com/NewsRoom/AttachmentNg/e4323281-f65c-48e8-b9c1-2857280eba39
