BISHA UPDATE – AGREEMENT
FOR STATE PARTICIPATION SIGNED
Nevsun
Resources Ltd., (NSU-TSX/AMEX) (“Nevsun”) is
pleased to announce that it has arrived at
agreement with the Government of the State
of Eritrea through the Eritrean National
Mining Corporation (“ENAMCO”) regarding the
State’s participation in the Bisha Project.
This is a precursor to the finalization of
discussions regarding a mining agreement for
the Bisha Project.
As a
very strong signal of support for the Bisha
Project, the Government has agreed to
purchase at fair value a 30% paid
participating interest, to add to its 10%
free participating interest provided by the
country’s mining legislation, resulting in a
total participation of 40% (30%
contributing; 10% free carried). ENAMCO will
pay the full fair value for its share of the
project determined by an independent
valuator at the time of Bisha’s first gold
shipment.
In late
2006 the Government established ENAMCO for
the purpose of holding ownership interests
and to promote the development of the mining
industry in Eritrea. Over the course of the
past number of months Nevsun and ENAMCO have
worked together to arrive at a fair and
reasonable method for the determination of
fair value, based on a reliable and
independent process. The first step will see
a provisional payment by ENAMCO within three
months of this agreement. At the time of
Bisha’s first gold shipment an independent
professional valuation will be conducted
using a discounted cash flow analysis based
on the Bisha feasibility study financial
model, updated for the market consensus for
metal prices, actual capital costs incurred,
and applying the then applicable discount
rate.
This
participation allows both parties to move
forward together as partners in the Project
and are beneficial to the Project, the
Company and the Government of Eritrea in
many ways:
-
Positive Government support will help
expedite all local requirements,
reducing risk of disruption
-
Early
cash contribution by the Government
provides the Company with some of its
immediate capital funding requirements
-
Reduced political risk with the Eritrean
Government as a major shareholder
-
Government provides proportionate share
of capital to build the mine (33.3%) and
shares the risk of capital spend (and
over-run facilities) for loan financing
With the conclusion of this milestone the
Ministry of Energy & Mines has assured
Nevsun that the mining license and the
underlying Mining Agreement for Bisha will
be advanced very promptly. The
Company looks
forward to the Government’s continued
support.
In
addition to the project purchase price, the
Government will fund its pro-rata 33.3%
share of capital expenditure for the Project
(33.3% = 30/90ths of contributing
interests).
Naturally the future market will have a
significant bearing on the final purchase
price. The feasibility study demonstrates
quite clearly that the Bisha Project is most
sensitive to metal prices and is very much
less sensitive to capital costs and
operating costs. The project is financially
robust as a result of low operating costs
throughout the mine life.
The
following provides a technical summary of
the Bisha project and the capital and
operating costs estimated in the feasibility
study.
The Bisha Deposit
The
Bisha deposit is configured in three
distinct layered zones – a 35m thick surface
oxide zone having a high gold and silver
content immediately overlying a 30m thick
copper enriched supergene zone which itself
overlies a primary sulphide zone containing
both zinc and copper. Significant byproduct
gold and silver are recoverable from both
the supergene and primary ores.

Processing
Processing of the three
ore types will utilize a common crushing and
SAG/ball grinding circuit, but will require
three different extraction and processing
circuits. After grinding, gold and silver
will be extracted from the oxide ore by
conventional cyanide leaching and recovered
by the carbon in pulp process. Later in the
project the supergene and primary ores will
be processed by a conventional flotation
process to recover copper and zinc as
concentrates for direct sale to smelters.
The tailing systems will be common for all
three ore types.
The feasibility study
envisages the mining and processing of each
zone in succession starting with the surface
oxide zone. Before the oxide ore is
exhausted the copper flotation process
equipment will be installed and commissioned
so that a smooth transition can be made from
oxide ore to the supergene ore treatment.
Similarly, before the supergene ore is
exhausted, the additional flotation
equipment required to recover the zinc from
the primary ore will be installed and
commissioned to permit a smooth transition
from supergene to primary ore.
In the first two years of
production, gold and silver will be
extracted together. Production of copper
concentrate will begin with a minor amount
in Year 2, significant quantities for Years
3 to 5, and smaller quantities in Years 6 to
10. Zinc concentrate production occurs only
in Years 6 to 10.

-
The operating cost per ounce for
gold is after taking silver
production as a credit.
-
The gold produced from the
supergene and primary is taken
as a byproduct credit to copper
and zinc.
-
The operating cost per pound for
copper from the supergene is
after taking silver and gold as
credits.
-
The operating cost per pound
during the primary phase has not
been presented in the table so
as to avoid potential
misinterpretation regarding
allocations of credits.
Depending upon metal prices at
the time there may be greater
emphasis on zinc or copper
credits. If copper, gold &
silver were regarded as
byproducts in the zinc phase,
the operating cost of zinc would
be $0.06 per pound (base case).
