The project includes two scenarios, the unconstrained model, which disturbs Federal Bureau of Land Management land within the first year of development, and a constrained model, which will limit disturbance to private land for the initial three years of production.
According to the PFS, the project is expected to produce 598Mlb of molybdenum and 534Mlb of copper over a mine life of 42 years.
The construction cost of the Liberty project is estimated to cost about $556m for the unconstrained model and $573m for the constrained model.
