Hudbay has filed a technical report containing the results of the preliminary economic assessment of its Copper World Complex in Arizona.  It includes the recently discovered Copper World Deposits along with the Rosemont deposit.

Highlights of the report include a two phase mine plan that has an after tax net present value of 1296 million dollars and generates an 18 percent rate of return at $3.50 per pound copper.  The processing facilities are planned to have annual production capacity of 100 thousand tonnes of copper cathode during Phase One and 125 thousand tonnes of copper cathode during Phase Two and have been designed to reduce the project’s carbon footprint to produce “Made in America” copper.

Phase One reflects a stand along operation on private land and patented mining claims over a 16 year mine life with average annual copper production of approximately 86 thousand tonnes and Phase Two expands mining activities onto federal land and extends mine life to 44 years with average annual copper production of approximately 101 thousand tonnes.
