NPV for Kun-Manie: $84 million Post Tax
(all financial figures are in US dollars)
Amur Minerals Corporation (AIM: AMC), the exploration and development company
focused on the Far East of Russia, announces the results of the SRK Consulting
Pre Feasibility study on its Kun-Manie nickel sulphide deposit located in
eastern Russia. The projections in the study indicate a Post Tax NPV (10%) of
$84 million with an IRR of 15.7%. At approximately 16,000 tonnes of nickel
contained in concentrate per year, the facility would be one of the largest new
nickel sulphide producers since the discovery of Voisey's Bay.
Key Production Parameters:
•Production of ore will be derived from three ore bodies;
•The mine and plant will operate 365 day per year;
•Seasonal roads will be used for 8 months each year to deliver concentrate
and supplies between the site and rail head;
•Annually, four million tonnes of ore are proposed to be mined by open pit
methods with a stripping ratio of 2.9 to 1.0 - one of the lowest stripping
ratios associated with nickel sulphide mines worldwide;
•A Probable Ore Reserve of 31.5 Mt with mean grades of 0.54% Ni and 0.15%
Cu has been derived from the previously reported Measured and Indicated
Mineral Resource.
•The production schedule envisages that a total of 38.2 million tonnes
(Mt) of ore at a grade of 0.55% nickel and 0.15% copper containing 210,000
tonnes of nickel and 59,000 tonnes of copper will be delivered to the plant
providing a ten year mine life. This schedule includes a portion of Inferred
Mineral Resources. All mine production has been adjusted to reflect mining
loss and dilution assumptions; and
•The projected 76% metallurgical recovery will yield a total of 159,000
tonnes of nickel and 43,000 tonnes of copper.
Key Financial Parameters:
•Initial capital expenditure is projected to be $331 million. This
includes the construction of a road to the site, all necessary ancillary
structures, a processing plant, the tailings dam, mining fleet,
preproduction mining, haul road construction and transport fleet.
Engineering, procurement and construction management and contingencies are
included. Approximately 42% of the initial capital cost relates to the
construction of a seasonal access road;
•A total of $66 million sustaining capital is projected over the 10 year
mine life. This includes replacement of the mining and transport fleets as
well as expansion of the tailings impoundment area as required;
•The total operating cost to generate a tonne of concentrate and deliver
it to the nearest rail load out facility is projected to be $16.63. This
includes mining, processing, tailings disposal, royalties, administrative
and transport costs ;
•The combined cost per ore tonne for rail transport and smelter charges is
projected to be $6.33 per ore tonne;
•The total cost to generate a pound of nickel will be $2.51 including
mining, processing, administrative, and all transportation fees. This
excludes the contribution made from by-products;
•The projected Post Tax NPV (10%) is $84 million with an IRR of 15.7%.
This is based on post-tax projections - the most conservative approach to
reporting on a project's economic potential; and
•The nickel price utilised in the evaluation study is $7.50 per pound
($16,530 per tonne), compared to an average price for the first 11 months of
2007 of $17.30 per pound. Each dollar per pound increase adds more than $100
million to the NPV (10%).

Robin Young, Chief Executive Officer, Amur Minerals commented:
'Our primary objective was to determine if the resource we have identified to
date is large enough to justify the significant capital expenditure required due
to the remote location of Kun-Manie. This report confirms that the first phase
of the Kun-Manie development is economic. It also confirms our belief that
Kun-Manie will be a premier nickel producer when in production.
'Multiple undrilled targets remain and we have not yet defined the limits of the
mineralisation in two of our drilled deposits, all of which is recoverable by
open pit mining. There is the potential to more than double the resources on the
site.
'These open pit mineable ore bodies will provide a solid platform for further
development. The exploration of additional defined targets of similar grade in
the immediate area will add to the upside of the project and the potentially
higher grade, larger targets of Yan-Hegd and Chorny Espiline could significantly
change the scale of the operation.
'With the completion of the study, Amur has entered a new era: every tonne of
newly drilled nickel will now increase and enhance the economic potential of the
project.'

General Description of the Project
The project is based on a single simple concept that consists of generating a
sulphide concentrate for sale on the international market. Conventional open pit
mining and flotation of the ores serve as the base case. The concentrate will be
trucked from the site over a 320 kilometre long road for delivery to the rail
head at Ulak located on the Baikal Amur railroad in the Amur Oblast. From there,
it will be transported by rail to a commercial smelter. For rail transport
costing, it has been assumed that the concentrate will be shipped a maximum
distance of 5,000 kilometres. There are several smelters located within this
distance of the site.
The project will require the construction of a 320 kilometre long road, to allow
truck access to the site over 8 months of the year, as well as the construction
of a power line. The local state owned utility company has stated it will cover
the capital expenditure to construct the power line and offset this investment
by utilising a higher cost per kilowatt hour for power consumption. Surveys for
the road and power line will be commissioned over the next year and final
engineered designs will be submitted to the Local Government for approval.
The site will be operational throughout the year. Mine production will be
derived from pits located along the Krumkon Trend within the Ikenskoe,
Vodorazdelny and Maly Krumkon deposits. Mining will result in the delivery of
4.0 million tonnes of ore per year to the mill, which is planned to be
constructed approximately midway between the three deposits. Waste will be
placed in dumps located adjacent to the pits. An average stripping ratio of 2.9
tonnes of waste per tonne of ore is anticipated.
The mill is planned to treat 4.0 million tonnes of ore per year and is projected
to have an overall recovery of 76%. This recovery is based on metallurgical test
work completed by Sibsvetmetniproject of Krasnoyarsk with adjustments by SRK
Consulting metallurgical engineering staff. The mill tailings will be stored
within an impoundment adjacent the mill site. The concentrate will be
transported by truck during an eight month period and stored at a secured yard
next to the rail head in Ulak. Monthly shipments to the smelter will provide a
stable production cycle and recovery of revenues.
The smelter has not been identified in the study. The terms for smelting the
concentrate were derived from an unsolicited smelter schedule identifying
payment and charge parameters. Payments for delivered nickel will range from 61
to 67% of the contained nickel and 50% of the contained copper. As the smelters
are land-locked the Company has assumed that the freight costs can be shared.
The Company believes that these terms can be significantly improved.
Identified Areas Of Upside Potential to Improve Results
The study has not optimised the operation nor was it intended to accomplish
this. It was intended to establish the current viability of the existing
mineralisation to support the operation as a large low grade producer. There are
numerous areas of potential improvement as follows:
• Exploration potential remains very high within the property limits and
additional resources could be added thereby expanding the mine life and
impacting the overall annual production rate. The limits of the
mineralisation within the Maly Krumkon and Ikenskoe pits have not been
established. These could be enlarged and this next season's drill programme
will continue to conduct step out drilling within these two areas.
Successful results will extend the life of the mine and may permit selective
mining wherein higher grades could be delivered to the mill earlier in the
production cycle. In addition, the Chorney Espiline, Kubuk and Falcon
targets have not been drilled. These could add mineable resources . Yan Hegd
also represents a large target that could provide added resources;
• The access road represents approximately half of the initial capital
expenditure. The study results are based on large scale maps. Flights over
part of the route indicate that there is potential to minimise costs over
approximately half of the route though the principal objective of further
studies will be to identify a low-cost route over a watershed and to firm up
the cost estimate.
• The Maly Krumkon pit was not optimised and optimisation studies are
expected to increase the size of the open pit;
• Metallurgical test work has not been optimised. Follow up work is needed
to determine the extent of improvement in metallurgical recoveries and
concentrate quality potentially improving the global project economics;
• The smelter schedule used in this analysis was an unsolicited offer. It
has not been negotiated and can therefore be considered to be onerous to the
project. In addition, Brook Hunt has documented that in 2012 there will be a
shortage of sulphide concentrate available to toll smelters as smelter
capacities are projected to increase while sulphide nickel production will
decrease. The Company believes it is better to delay detailed negotiations
until a later date when better terms may be available that would further
enhance the project economics;
• Alternative metallurgical processes will be investigated in the near
term. As there is a large hydroelectric dam within the Amur Oblast, the
Company considers that there could be potential for smelting of the
concentrate by using flash smelting and / or electric arc furnaces that will
result in the generation of a saleable matte. Successful results would
reduce the cost to produce a pound of metal, recover a higher percentage of
the contained metal value and allow for the recovery of revenues from the
cobalt and other minor constituents. Concurrently, rail transport costs
would also be significantly reduced. The Company also intends to examine
hydrometallurgical processes; and
• A comprehensive evaluation of the preferred size and scale of the
operation is required. This will include a series of trade off studies that
will establish the final configuration of and its production capacity.
