News Release
11 November 2010
Tropicana Gold Project Development Approved
Development of the Tropicana Gold Project in Western Australia has been
approved by the Boards of AngloGold Ashanti Ltd and Independence Group NL.
AngloGold Ashanti has a 70% interest in the Project, which is located 330
kilometres east-northeast of Kalgoorlie in WA, and Independence Group has 30%.
The approved project will produce 3.45 million ounces of gold over a 10 year
mine life at a cash cost of A$710-A$730/oz (US$696/oz-US$715/oz*). In the first
three years of operation, gold production will be between 470,000-490,000 ozpa
at a cash cost of A$580/oz-A$600/oz (US$568/oz-US$588/oz*).
Capital expenditure, including pre-production operating costs, is estimated at
A$690-A$740 million (Real) or A$725-A$775 million (Nominal - including
escalation). At current exchange rates* this equates to US$676-US$725 million
or US$711-US$760 million, respectively. The higher production rate in the first
three years will contribute to accelerated payback.
Discovered in a remote, barely-explored area not previously thought prospective
for gold, Tropicana is the most significant gold discovery in Australia for
more than a decade. The Tropicana Joint Venture's first mover advantage has
enabled it to peg the bulk of what is now recognised as a major new gold field.
Construction will begin in the June quarter of 2011 and first gold is
anticipated in the December quarter of 2013.
"Tropicana is the first of AngloGold Ashanti's major gold discoveries to move
into production," said CEO Mark Cutifani. "We're delighted to give the green
light to its development."
"This is a clear demonstration of the impact an innovative, results-driven
exploration program can have on organic growth," Cutifani said.
"It's gratifying to be developing our own projects at a time when so many
majors are forced to pay huge premiums to fill their project pipelines."
The decision to commit to development follows the successful outcome of a
Bankable Feasibility Study (BFS) based on open cut mining of the Tropicana and
Havana deposits. The BFS does not take into account possible production from
the Boston Shaker or Havana Deeps deposits.
The approved project will utilise conventional drill and blast, truck and
excavator open cut mining methods carried out by a mining contractor. The 5.8
million tonnes per annum capacity (fresh ore) process plant has been designed
for water and energy efficiency, with the comminution circuit comprising
two-stage crushing, high pressure grinding rolls and ball milling, followed by
a carbon-in-leach circuit for gold recovery (see Figure 1).
The BFS was based on a Proved and Probable Reserve of 48 Mt grading 2.2 g/t for
3.4 million ounces of gold (see Table 1 in Appendices). The BFS mining
inventory totalled 59 million tonnes grading 2.0 g/t for 3.8 million ounces.
Whilst the initial mine life is estimated at 10 years, the Joint Venture
partners are confident this can be extended.
Step-out exploration drilling in late 2009 returned significant results from
the Boston Shaker prospect, which lies approximately 360m north of Tropicana
resource. Drilling to date has identified the faulted offset of Tropicana
mineralisation over an 850m strike length and the mineralisation remains open
at depth (see Figure 2).
An open pit scoping study based on data available to July 2010 has been
completed on Boston Shaker and indicates that an expansion to the current BFS
open pit resource is highly likely. Boston Shaker progressed into full
feasibility study in September 2010, with completion targeted for the first
half of 2011.
Significant results were also received from the Havana Deeps prospect, which
represents extensions of the Havana mineralised system external to the Havana
open pit.
The recently-completed Havana Deeps scoping study, based on drilling data to
the end of July 2010, indicates the potential viability of underground mining
at Havana Deeps (see Figure 4).
Although it is too early to determine the scale or timing of underground
mining, it could commence in parallel with open pit mining, once a suitable
portal position is available in the open pit. It is anticipated that Havana
Deeps will progress into a pre-feasibility study in early 2011.
The potential of Havana Deeps has been highlighted by a recent deep step-out
exploration drill hole, which intersected the mineralised package at 1km depth,
in excess of 2.1 km down plunge of the Havana open pit design. Assay results
are awaited (see Figure 5).
Work is in progress to incorporate the results of the Boston Shaker and Havana
Deeps scoping studies, along with subsequent drilling results, into a revised
resource estimate by year-end.
Encouraging intersections have also been returned by recent infill RC drilling
at the Crouching Tiger Prospect, 250m south of the Havana South BFS pit
outline, including 11m @ 5.27 g/t from 102m, 13m @ 1.47 g/t from 147m
(including 7m @ 2.27g/t) and 10m @ 1.69 g/t (including 4m @ 3.24g/t). (Table 2;
Figure 2)
In addition to the upside in the immediate mine area, the Joint Venture has
more than 30 exploration targets within trucking distance of the mine, along
with numerous anomalies on its 16,000 square kilometre tenement holding in the
highly prospective Tropicana Belt (see Figure 6).
Graham Ehm, EVP Australasia, said Tropicana would add to production from the
100% owned Sunrise Dam mine to lift AngloGold Ashanti's Australian gold output
to 600,000 ounces per annum by 2014.
"Tropicana will rank as the fifth largest contributor to the company's global
production in its first three years and will double the operating cash surplus
generated by the Australian region," Ehm said.
He said the Project would employ up to 550 people during construction, and up
to 450 people during operations, as well as contributing an estimated A$836
million to the WA economy during construction and a further A$825 million
during operations**.
Infrastructure will include 220 km of new road from Pinjin to the site, a
sealed all-weather airstrip and development of a borefield 50 km from the mine
site for water supply. The mine will operate on a fly-in, fly-out basis.
Tropicana was approved by the WA Minister for the Environment, the Hon Donna
Faragher, in October. Approval by the Federal Minister for Sustainability is
anticipated by the end of the year.
