Redhawk Reports Results of Copper Creek Project Scoping Study

27/02/2009 6:07pm

Marketwired Canada


Redhawk Resources, Inc. ("Redhawk" or the "Company") (TSX
VENTURE:RDK)(FRANKFURT:QF7), through its wholly owned subsidiary Redhawk Copper,
Inc., is pleased to announce the results of a Scoping Study (Preliminary
Assessment) on its 100% owned Copper Creek Project located in the Bunker Hill
Mining District, Pinal County, Arizona. The Scoping Study was prepared by KD
Engineering of Tucson, Arizona under the direction of Joseph M. Keane, P. Eng.,
of KD Engineering pursuant to National Instrument 43-101, Standards for
Disclosure for Mineral Projects of the Canadian Securities Administrators. The
Scoping Study is based upon NI 43-101 compliant resource estimates prepared by
Independent Mining Consultants ("IMC") of Tucson, Arizona and released on
October 29, 2008. Golder Associates, Milne & Associates, WestLand Resources,
Call & Nicholas Engineers, and METCON, all well recognized consulting firms,
contributed to the Scoping Study authored by KD Engineering. All dollar numbers
in this news release and in the Scoping Study are in $US.


The Scoping Study financial analysis is pre-tax and based upon an initial mining
rate of 2,500 tons per day ("TPD") in near surface breccia resources and
increasing to 10,000 TPD as the deeper porphyry resources get developed. Using a
copper price of $2.25 per pound, $15.00 per pound molybdenum, $600 per troy
ounce gold, $10 per troy ounce silver, and $1000 per pound rhenium, the economic
analysis results in a pre-tax NPV of $80.8 million and an IRR of 11% at a 7.5%
discount rate. The breakeven copper price is $1.80 per pound (NPV of zero at a
zero discount rate). At a 7.5% discount rate, a NPV of zero is produced at a
copper price of $2.09 per pound. The NPV of the project based upon the
approaches and costs utilized in the Scoping Study at various discount rates is
shown below:




Discount Rate          Pre-Tax NPV

0%                 $ 545.2 million
5%                 $ 175.6 million
7.5%               $  80.8 million
10%                $  18.3 million



Joe Sandberg, President of Redhawk, commented: "The Scoping Study is a thorough
and conservative baseline starting point to evaluate and improve the economics
of the Copper Creek project. The Scoping Study was initiated in May 2008 when
metal prices were well above levels seen today and correspondingly many of the
costs used were also at higher levels. A 25% to 30% contingency has also been
built into this financial analysis. Redhawk believes the Copper Creek project
has considerable upside both in terms of exploration potential of the district
and potential enhancement of the project economics. The Company has identified
numerous factors that reasonably can be expected to dramatically improve the
project economics. These include reduction of the current 5.25% net smelter
royalties; potential open pit production from the Old Reliable breccia deposit
(briefly discussed in the Scoping Study); realization of significant gold and
silver credits from the Keel and American Eagle deposits with additional assay
information; possible reduction in mining costs in certain of the breccias if
development shows ground conditions to be better than the current study
anticipates; and the discovery of additional high grade resources from the 80%
of Copper Creek which has not been explored including more than 400 additional
known breccias. Redhawk, along with many others in the mining industry, believes
that metal prices will recover to better levels as the world economies improve
and Copper Creek, which could be in operation in a three to five year time
frame, will be a very attractive US based project when this occurs."


A summary of the inputs, methodology, and results of the Scoping Study are
discussed below. For complete information on the Scoping Study inputs,
methodology, and results, the reader is referred to the complete Scoping Study
that will be posted on SEDAR.com.


The Copper Creek property consists of more than 5,000 acres (2,030 hectares) in
one contiguous block on the west flank of the Galiuro Mountains, approximately
75 miles (121 km) north east of Tucson, Arizona. The Copper Creek resources
consist of numerous "higher grade" breccia hosted deposits and deeper "porphyry
like" deposits of Laramide age and situated within the southwest porphyry copper
province of North America. The deposits host significant copper mineralization,
many with strong molybdenum contribution, and by-product silver and gold.


IMC estimated Measured, Indicated, and Inferred Resources of the Copper Creek
project at cutoff grades of 0.75% copper equivalent ("CuEq") in the breccia
deposits and 0.60% CuEq in the porphyry deposits as follows:

The Scoping Study base case involves initial mining from the surface and near
surface breccia resources at a rate of 2,500 TPD increasing to 10,000 TPD as the
Keel and American Eagle ("AE") porphyry deposits are developed. Mining in the
breccias is anticipated to be a combination of blast hole stoping with fill and
mechanized cut and fill methods. Mining in the Keel and AE is anticipated to be
post-pillar room and pillar with engineered fill. Based upon the above mining
rates and methods, cutoff grades of each of the deposits were calculated using
$2.25/pound (lb) copper, $15.00/lb molybdenum, $600/troy ounce (oz) gold,
$10.00/troy oz silver, and $1000/lb rhenium. The breakeven cutoff grades used
were 1.00% CuEq for the Childs, Prince, and Globe breccia deposits; 1.30% CuEq
for the Mammoth and Old Reliable breccia deposits; and 0.70% CuEq for the Keel
and American Eagle deposits. Indicated economic resources are shown in the table
below:

At a mill feed rate of 3.6 million tons per year (10,000 TPD), this would
indicate a mine life of approaching 30 years, depending upon mining recovery
rates. Due to the recent downturn in the price of copper, a higher cutoff grade
than the breakeven cutoff grade of 0.70% CuEq, indicated for the Keel and
American Eagle deposits, was considered more appropriate to use as a base case.
At a 0.90% CuEq cutoff grade, the resulting indicated and inferred tons and
grades for both deposits is shown in the table below:

The smaller tonnage is still generally contained in discreet blocks, or lenses,
that lend themselves to good stoping shapes for efficient mining. At the 3.6
million tons per year mill feed rate, the resource would indicate about 10.5
years of mine life using a 70% mining recovery. As the first 3 to 4 years of
production are from the breccias, the remaining years of production are from the
Keel and AE resources that are above 0.80% CuEq cutoff to complete a minimum
mine life of 20 years. At a cutoff grade of 0.80% CuEq, an additional 23 million
tons, at an average grade of 0.97% copper and 0.024% molybdenum, would become
available extending the mine life to over 21 years.


Capital expenditures in the Scoping Study are estimated as shown below:



Mine Development       $268,159,000

Tailings Facility        26,455,000

Environmental             2,029,000

Plant and Equipment      92,454,000
                       ------------

TOTAL MINE AND MILL    $398,098,000
                       ------------
                       ------------



The current mining plan calls for a phased approach with the majority of the
capital contributions spread over the initial three years of mine development.

About Redhawk

Redhawk is a Canadian-based resource exploration and development company with
primary focus on the accelerated development of its advanced stage Copper Creek
copper-molybdenum project in San Manuel, Arizona. The Company also has two
gold/silver properties in Nevada.


The 100% owned Copper Creek property consists of approximately seven square
miles of almost totally contiguous patented and unpatented mining claims and
state prospecting permits, located about 70 miles northeast of Tucson, Arizona
and about 15 miles east of San Manuel. The property is in the prolific southwest
US porphyry copper belt at the projected intersection of a major northwest belt
of porphyry copper deposits or mines (Ray, Miami/Globe, Superior/Resolution,
Johnson Camp) and a major east-northeast belt of porphyry deposits (San
Manuel/Kalamazoo, Silver Bell, Lakeshore, Safford, Morenci). The property is
within sight of the former BHP Kalamazoo/San Manuel copper smelter and mine and
within 30 miles of an existing operating copper smelter. The area is a mining
friendly and politically secure location with excellent and readily accessible
infrastructure.


Mineral resources that are not mineral reserves do not have demonstrated
economic viability. The Scoping Study (preliminary assessment) includes inferred
mineral resources that are considered too speculative geologically to have the
economic considerations applied to them that would enable them to be categorized
as mineral reserves, and there is no certainty that the preliminary assessment
will be realized.
