Redhawk Reports Positive Preliminary Economic Assessment for Underground Mining of Copper Creek Project

 

 

 

 

 

Redhawk Resources, Inc. (TSX:RDK)(OTCQX:RHWKF)(FRANKFURT:QF7) is pleased to report the results of a Preliminary Economic Assessment using independent consultants Milne and Associates, Call & Nicholas, Inc., Golder Associates, SGS METCON/ KD Engineering, Westland Resources, and Independent Mining Consultants.
PEA Highlights:

 



--  Pre-tax NPV of US$488 million at 7.5% Discount Rate and US$794 million
    at 5% Discount Rate and 16% IRR at US$3.30 copper over 18 year life of
    mine

--  Average total operating cash cost of US$1.74 per pound copper net of
    byproduct credits

--  Average annual production of 121.7 million pounds of salable copper
    (55,200 metric tons)

--  Production rate of 25,000 short tons per day mining and milling

--  Milling produces 30% copper concentrate and a separate molybdenum
    concentrate

--  92% copper recovery in flotation mill

 

 

The PEA uses a mining and milling rate of 25,000 short tons per day (tpd). Mining is by room and pillar/post pillar with backfilling method in the porphyry deposit and results in approximately 75% recovery of the resource. Mining of the near surface breccia deposits is by cut and fill or blasthole stoping and fill with very high recovery of the resource. A small open pit may be used to mine the Old Reliable breccia, but is not considered in the current PEA. Milling is by standard flotation and produces a copper concentrate and a molybdenum concentrate with 92% copper recovery and 30% copper concentrate grades. All dollar figures are in $US. The resource used in the PEA is the NI 43-101 compliant resource reported December 20, 2012.
R. Joe Sandberg, President and CEO of Redhawk, commented; “The results of the 2013 PEA confirm the economic potential of the Copper Creek Project and a successful growth in project scale from a 10,000 tpd operation in the 2009-2010 NI 43-101 Scoping Study to the 25,000 tpd operation in the current NI 43-101 PEA. Management believes there are several aspects of the PEA that can be further optimized based upon additional work. In addition, the drilling in 2010-2012 and the ongoing geologic work in the district suggests the potential for significant expansion of the existing resources and identification of several very large untested porphyry targets on the Redhawk controlled lands. The Company will announce these resource expansion plans and further development plans in separate news releases.”
The table below shows the pre-tax Net Present Value at 5% Discount Rate and 7.5% Discount Rate, Internal Rate of Return and payback period for copper prices between $3.00 and $3.60 per pound.
