Marketwired Canada
Los Andes Copper Ltd. ("Los Andes", or the "Company") (TSX VENTURE:LA) is
pleased to announce that the Company has filed a Preliminary Economic Assessment
("PEA") and an updated resource estimate on its 100% owned Vizcachitas porphyry
copper-molybdenum project ("Vizcachitas Project") located in Region V, Chile.
The PEA and updated mineral resources announced on December 13, 2013 was
prepared during the process of consolidation of the non-consumptive water rights
over a section of the Rocin River, Putaendo, Fifth Region, Chile, together with
the engineering and other studies and reports for the development of a
run-of-river hydroelectric project generation facility. Such consolidation took
place effective January 23, 2014. This updated PEA does not change in any way
the resource estimate or the technical and economic aspects of the PEA except
that it removes all references and economic calculations related to the
possibility that these water rights might not have been included in Los Andes.
The PEA was prepared by Coffey Consultoria y Servicios SpA (Coffey) and Alquimia
Conceptos S.A., and can be accessed under the Company's profile at www.sedar.com
and on the Company's website.
Resource Estimate Update
As part of the PEA the resource estimate for the Vizcachitas Project was updated
by Coffey. At a 0.3 % copper equivalent (Cu Eq) cut-off, the Indicated Resources
are 1,038 Mt @ 0.434 % Cu Eq (0.373 % Cu and 0.012 % Mo), containing an
estimated 8.5 billion pounds of copper and 281 million pounds of molybdenum, and
the Inferred Resources are 318 Mt @ 0.405 % Cu Eq (0.345 % Cu and 0.013 % Mo)
containing an estimated 2.4 billion pounds of copper and 88 million pounds of
molybdenum.
The estimate increases the Indicated Resources from the mineral resources which
had an effective date of June 9, 2008. The resource estimate was based on a
total of 146 drill holes and 40,383 metres drilled, including a total of 16
drill holes and 5,128 metres of drilling completed after the June 9, 2008
resource estimate.
The Mineral Resource estimates for different cut-off grades with an effective
date of January 23, 2014 are shown in the tables below:

-- Copper equivalent grade has been calculated using the following
expression: Cu Eq (%) = CuT (%) + 4.95 x Mo (%), using the metal prices:
$ 2.75 / lb. Cu and $13.6 / lb. Mo.
-- Small discrepancies may exist due to rounding errors.
-- The quantities and grades of reported Inferred Mineral Resources are
uncertain in nature and further exploration may not result in their
upgrading to Indicated or Measured status.
-- Mineral Resources are reported within a Whittle pit shell based on: Mine
Cost - 2.25 USD/t, Process Cost - 6.94 USD/t, Copper Price - 3.00
USD/lb, Molybdenum Price - 13.6 USD/lb. Conc. Copper Sales Cost - 0.5537
USD/lb., Conc. Molybdenum Sales Cost - 1.60 USD/lb., Recovery Copper -
90%, Recovery Molybdenum - 60%, Slope Angles - 42 degrees to 47 degrees.
PEA Highlights
The PEA evaluated four mining scenarios feeding flotation facilities with a
throughput of 44 ktpd, 88 ktpd, 176 ktpd and 88 ktpd with a step up in
production to a final throughput of 176 ktpd. The 176 ktpd case was selected to
be the base case as it produced the highest net present values (NPV).
The base case has a life of mine of 28 years, initial capital expenditures of
$2.9 billion, sustaining capital expenditure of $0.7 billion for the
construction of the second tailings dam facility and mine extensions, and
considered flat projected copper prices of $2.75/lb and molybdenum prices of
$13.64/lb.
On a pre-tax basis, the base case, results in an NPV of $746 million, internal
rate of return (IRR) of 11.4%, and an estimated payback period from initial
commercial operations (Payback Period) of 5.9 years. On an unlevered after-tax
basis, the base case, results in an NPV of $274 million, IRR of 9.5%, and a
Payback Period of 6.0 years.
Note: The Preliminary Economic Assessment is considered preliminary in nature
and 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 Economic Assessment will be realized. Mineral resources
that are not mineral reserves do not have demonstrated economic viability.
