redbank closes in on oxide copper production

MEDIA RELEASE 22 APRIL 2008
REDBANK CLOSES IN ON OXIDE COPPER PRODUCTION
NOTICE OF INTENT LODGED FOR START-UP COPPER PROJECT IN THE NORTHERN TERRITORY
Redbank Mines Limited (ASX: RBM – “Redbank”) has taken a key step towards a proposed low-capital
development of its Redbank Copper Project in the Northern Territory after lodging a Notice of Intent with the
authorities for the Stage 1 Oxides Project.
The Perth-based company said today (Tuesday) that it was confident of securing the necessary approvals within
4-6 months, enabling it to commence production within 12 months from heap leaching of the available oxides at
the key Bluff, Azurite and Redbank deposits – which contain oxide resources of some 1.0 million tonnes grading
1.4% Cu within 35 metres of the surface.
“We are moving as quickly as possible to fast-track this development, for which the preliminary feasibility study
completed last year estimated a capital cost of just A$5.2 million,” said Redbank’s Managing Director, Mr Gino
Vitale.
“This represents a remarkably low capital outlay to commence production and secure the Company’s position as
a niche producer of high-grade, high-quality copper concentrates at the Redbank Project,” he added.
“The Feasibility Study forecast that the Stage 1 Oxides Project would generate revenue of A$61 million and a
pre-tax cash surplus of A$20 million over an initial 2.5 year life, with capital payback being achieved in just over
12 months,” he added. “That was based on the then forward curve copper price of US$3.10/lb, with the spot
price since increasing to almost US$4.00/lb.”
The Oxides Project has been boosted by recent positive in-fill and resource definition diamond and RC drilling,
which has delivered some outstanding high-grade results including 29m @ 7.7% Cu from 13m down-hole and
24m @ 4.5% Cu from 15m down-hole at the Redbank Deposit and 8.0m @ 2.1% Cu from 4m down-hole and
12m @ 1.7% Cu from 4m down-hole at the Azurite Deposit.
“Indications from the recent drilling are that we will be able to further increase the grade and potentially the
tonnage of the currently defined oxide resources ahead of production commencing and this will result in
improved profitability” Mr Vitale commented.
The successful development of the Oxides Project will pave the way for a broader staged development of the
Redbank Project including the deeper sulphide resources. The 2007 Feasibility Study outlined an overall
production profile for the Project of 31,500 tonnes of copper over 5 years, with average copper production of
6,300 tonnes per annum.
This would deliver total revenue of $200 million over the projected five-year mine life based on resources within
the top 100 metres alone, with an average EBITDA of $12.0 million per annum. The Company is currently a
small-scale producer from the treatment of high-grade stockpiles to clear the processing area for the new heap
leach pads in anticipation of the commencement of mining later this year.
Redbank acquired the Redbank Project in 2005 and moved quickly to prove up its resource potential. Within 12
months, the Company secured a life-of-mine off-take agreement with international commodities group, Swissbased
Glencore. Last year, it announced an upgraded resource within four oxide deposits and three sulphide
deposits to 5,028,000t @ 1.4% Cu for 71,000 tonnes of contained copper metal
