Anglo American announces 750Mt West Wall Mineral Resource in Chile
Anglo American announces a Mineral Resource estimate for the West Wall copper
project in central Chile`s Valparaiso Region. Anglo American and Xstrata Copper
each have a 50% interest in the mining company which holds the project, West
Wall SCM.
The estimated Inferred Resource for the project`s Lagunillas deposit, based on
57 drill holes (33,600 metres), amounts to 750 million tonnes at a grade of
0.54% copper and 0.01% molybdenum, containing 4.0 million tonnes of copper using
a 0.3% copper cut-off grade. The Mineral Resource also contains estimated
average grades for gold of 0.05 grams per tonne.
The West Wall project is located 100 kilometres northeast of Santiago and 70
kilometres north of the Rio Blanco - Los Bronces mineral district. Porphyry
copper style hydrothermal alteration covers a large area of approximately seven
kilometers by three kilometers. Exploration activities have focused in the south
of the prospect at Lagunillas, where drilling has outlined copper sulphide
resources associated with porphyry intrusive bodies.
Anglo American Head of Exploration for the Andes Region and West Wall board
member, Vicente Irarrazaval, said: "This is an exciting new exploration
accomplishment. In recent years Anglo American has been very successful in
discovering copper deposits near our operations in Chile and we are pleased to
include a new greenfield discovery that shows promising potential to add to our
project development pipeline."
This is the first Mineral Resource estimate published by Anglo American for West
Wall.

*The Mineral Resource is reported at a 0.30% copper cut-off grade constrained to
a depth of 600 metres below surface. The Mineral Resource estimate, which is
reported in accordance with the Australasian Code for the Reporting of
Exploration Results, Mineral Resources and Ore Reserves, 2004 Edition (JORC
code), is reported without dilution or ore loss.
*Numbers in the above table are rounded, generally to two significant figures
with tonnes and grades for Inferred Resources and grades in the total column
rounded to one significant figure and the contained metal numbers rounded to
nearest 100k.
*Due to the uncertainty that may be attached to Inferred Mineral Resources, it
cannot be assumed that all or part of an Inferred Mineral Resource will
necessarily be upgraded to an Indicated or Measured Resource after continued
exploration.
*The information in this report that relates to Mineral Resources is based on
information compiled by Mr. Graeme Lyall, who is Member of the AusIMM and full-
time employee of Anglo American. Mr. Graeme Lyall has sufficient experience
which is relevant to the style mineralisation and type of deposit under
consideration and to the activity which he is undertaking to qualify as a
Competent Person as defined in the 2004 Edition of the "Australasian Code for
Reporting of Exploration Results, Mineral Resources and Ore Reserves". Mr.
Graeme Lyall consents to the inclusion in this announcement of the matters based
on his information in the form and context in which it appears.
