1.Feasibility Study -On or Near Site Mine Generation
See attached Exhibit A-1 for Revisions to the Scope of Work .These revisions are
discussed below:
A.Task 2 Revision
Discussion:This primary focus of this task will be to concentrate on constructing a large
coal plant at Bethel to supply the energy needs of the region and the Donlin Creek mine.
Stage 1 of coal plant to be competed in the year 2008 rather than 2011,since Nova Gold
has recently stated that it will need 40 MWs of power in 2008.Stage 2 is assumed to be
completed in 2012.A smaller 15-20 MW coal plant to supply the energy needs of the
region absent the development of the Donlin mine will not be investigated,since all
efforts need to be focused on providing accurate costs associated with constructing and
operating a large coal plant.The installation of 10-20 MW of backup diesel generation
originally included as part of this task will be now be included as part of Task 2,in
Exhibit B-1.Since Nova Gold wants 40 MWs of power by 2008,there will be little if any
addition time after this study to reevaluate the results of the study before a decision is
made to construct or not construct the coal plant at Bethel.Therefore,it is necessary to
shift focus of this task to the 80 MW coal plants so that the funding available for this task
will be effectively used to develop more accurate construction,operational and power
costs associated with power supply option.-
Suggested Revisions:Focus efforts on 80 MW coal plant.Delete work on 15-20 MW
coal plant.Include 20 MW of backup diesel generation as part of Task 2 in Exhibit B-1.
B.Task 3 Revisions
Discussion:The original scope of work presumed that Nuvista would construct an on-
shore power plant at Crooked Creek to supply the initial mine load as outlined in Task 2,
Exhibit B-1.The emphasis has now been shifted to constructing a multiple barge-
mounted power plant that would presumably be located at Bethel.Therefore,it is
necessary to evaluate both a 3 and a 14 million fuel tank farm at Bethel.
Suggested Revision:The scope of work for Task 3 modified to evaluate constructing both
a3 and 14 million gallon fuel tank farm at Bethel.
C.Task 5 Revisions:
Discussion:All involved parties,including Nova Gold,have recognized construction of
the 138 kV power line between Bethel and the mine site is a necessity first step in
providing lower cost power to the region,regardless of whether long term power is
supplied to the region and the mine,from a large generation plant located at Bethel or a
intertie to the railbelt.Since Nova Gold wants 40 MWs of power by 2008,there will be
little if any addition time after this study to reevaluate the results of the study before a
decision is made to construct or not construct the 138 kV transmission line from Bethel to
the Donlin mine.Therefore,it is necessary to shift focus of this task to 138 kV
transmission system so that the funding available for this task will be effectively used to
develop more accurate construction,operational and power costs associated with 138 kV
transmission system.The feasibility level analysis of the SWGR system and wind
generation,which was originally a part of the task could easily be postponed for a year
without any adverse effect on the region and could be the subject matter of a latter study.
It is estimated the cost of conducting a separate SWGR +wind generation feasibility
study would be $100,000.
Suggested Revision:Focus efforts on 138 kV transmission system.Delete evaluation of
SWGR system and wind generation as part of this task and make these items the subject
matter of a latter study.
D.Results of Implementing Suggested Revisions.The result of implementing the above
Suggested Revision will result in the development of more detailed feasibility level
designs,more accurate construction,operational and power cost for the 138 kV
transmission system and 80 MW coal plant.It is important to develop as accurate cost as
practicable using the existing funding as there will be little if any addition time after this
study to reevaluate the results of the study before a decision must be made to move
forward with the construction of the 138 kV transmission line and/or 80 MW coal plant at
Bethel.
2._Feasibility Study -On or Near Site Mine Generation
See attached Exhibit B-1 for Revisions to the Scope of Work .These revisions are
discussed below::
A.Change name of Feasibility Study to:Donlin Creek Mine Interim Power Supply
B.Task 2 Revisions
Discussion:The original scope of work submitted for the above feasibility study was to
evaluate the feasibility of constructing a diesel power plant at Crooked Creek to supply
the initial mine load estimated at approximately 25 MWs,for a period of 5-6 years,while
lower cost long term permanent power is made available to the mine site.As suggested
in the recent Calista Region Energy Needs Study Part I,long term power would be supply
from a large coal plant built at Bethel and delivered to the mine site via a 138 kV
transmission line.However,just recently Nova Gold has stated that the initial mine load
would be in the order of 40 MWs.It would require a power plant with an installed
capacity of approximately 55 MWs,assuming the use of 5 MW diesel generator sets,to
reliably supply a 40 MW load.The above study suggest that the region and the mine
would be better served by constructing generation facilities at Bethel and a 138 kV line to
the mine rather than constructing a large generation plant at Crooked Creek to serve the
mine load.Furthermore,all involved parties,including Nova Gold,have recognized
construction of a power line between Bethel and the mine site is a necessity first step in
providing lower cost power to the region,regardless of whether long term power is
supplied to the region and the mine,from a large generation plant located at Bethel or a
intertie to the railbelt.
Suggested Revisions:The scope of work for Task 2 be amended to evaluate the
feasibility of supplying the initial mine load of 40 MW from a barge mounted diesel plant
located at Bethel rather than an on-shore power plant located at Crooked Creek.It is
recognized that for various reasons the construction of the 138 kV transmission line may
be delayed past 2008.To accommodate this contingency it is suggested that the diesel
power plant be constructed on multiple barges that could not only be towed to Bethel,but
also small enough to be towed up the Kuskokwim River to Crooked Creek,in the event
construction of the 138 kV transmission line was delayed past 2008.Such an approach
would provide maximum flexibility in locating the power plant.
C.Task 3 Revisions
Discussion:The original scope of work presumed that Nuvista would construct an on-
shore power plant at Crooked Creek to supply the initial mine load as discussed in Task 1
above.The emphasis in Task 2 has now been shifted to constructing a multiple barge
mounted power plant that would preferable be located at Bethel.The funds for Task 3
need to be redirected to evaluate constructing the fuel tank farm at Bethel rather Crooked
Creek.In the event the 138 kV transmission line could not be built in a time manner,and
the barge mounted power plant is located at Crooked Creek,Nuvista could looked to
Nova Gold to construct the necessary fuel storage facilities.
Suggested Revisions:The scope of work for Task 3 be modified to evaluate constructing
the fuel tank farm at Bethel rather Crooked Creek.Note:Preliminary cost estimates were
prepared by LCMF for an 8 million gallon fuel tank farm at Crooked Creek in Part II of
the Calista Region Energy Needs Study.While these cost estimates will not be as
accurate as the cost estimates that will be developed as part of the feasibility study,they
can be used to estimate the cost of constructing fuel storage at Crooked Creek and the
power costs associated with this option.
D.Results of Implementing Suggested Revisions.The result of implementing the above
Suggested Revision will result in the development of feasibility level design,cost
estimates and economic evaluation of a multiple barge mounted power plant that can be
used at either Bethel or Crooked Creek.

INTRODUCTION
The State of Alaska legislature has recently appropriated $280,000 to Nuvista for the purpose of
conducting a feasibility study to examine the feasibility of constructing a coal-fired generation plant
at or near Bethel,Alaska and regional transmission system to supply the electric power and energy
needs of the Calista region.The following paragraphs describe the approach and methodology that
will be used in preparing the feasibility study.
SCOPE OF SERVICES
Upon receipt of a notice-to-proceed,immediate steps will be undertaken to implement the work.The
first step after receiving notice-to-proceed will be to meet with Client's personnel and/or
representative to discuss and establish realistic timelines for completion of the feasibility study.
The Scope of Services will be performed in a manner that is consistent with standard engineering
feasibility study practices.To insure the work completed under each task corresponds to the realistic
expectations of the Client,input and comments will be solicited from Client's personnel and/or
representative throughout the course of preparing the study.
A proposed seven-member project team has been assembled to prepare the feasibility study.Each
team member has been carefully selected to supply an essential expertise that is necessary for the
successful completion of the study.Each team member will be responsible for completing one or
more of the eleven major project tasks.Mr.Frank Bettine will serve as the project manager and all

TASK 2 -COAL PLANT FEASIBILITY DESIGN AND CONSTRUCTION COST ESTIMATES
Description of Work Included:
This task will develop a feasibility design,construction and operational cost for building and
operating a coal-fired power plant,to supply the electric energy needs of the Calista region,both with
and without the development of the Donlin Creek gold mine project.It is assumed that any coal-
plant constructed to supply the power needs of the Donlin Creek mine would be built in two stages:
Stage 1 to be completed and operational on or about the year 2008 and Stage 2 to be completed and
operational on or about the year 2012.It is also assumed that the total generation capacity of the coal
plant will be in the neighborhood of 80 megawatts,with approximately one-half this amount
installed by the year 2008.However,the final generation capacity and construction schedule will be
determined following further consultations with Nova Gold:.The primary focus of this task will,
be to develop accurate costs associated with constructing and operating a 80 MW +coal-plant to
supply the power needs of the region and the Donlin Mine project.A field trip has been made to
Bethel to identify potential locations for the power plant.
Under this task a feasibility level design will be prepared in sufficient detail to obtain construction
cost estimates accurate to within +15 percent of expected construction cost,which is typical of the
accuracy associated with a feasibility level study.This will be accomplished by working closely with
and soliciting cost estimates from qualified material suppliers and construction contractors.Various
coal combustion technologies will be investigated to determine which technology will be the most
appropriate.
Since power costs are highly dependent on delivered coal costs,significant efforts will be expended
to identify available coal sources and to accurately identify the cost of providing coal to a coal plant
in Bethel.
A district heating system feasibility level design will also be prepared for the purpose of obtaining
a cost estimates for constructing and operating a district heating system in the community of Bethel.
Waste heat from the coal-plant and/or interim barge mounted diesel power plant would be used to
supply heat to the district heating system.

INTRODUCTION
The State of Alaska legislature has recently appropriated $200,000 to Nuvista for the purpose of
conducting a feasibility study to examine the feasibility of constructing a combustion turbine or slow
speed diesel plant at or near the Donlin Creek mine site.The following paragraphs describe the
approach and methodology that will be used in preparing the feasibility study.
SCOPE OF SERVICES
Upon receipt of a notice-to-proceed,immediate steps will be undertaken to implement the work.The
first step after receiving notice-to-proceed will be to meet with Client's personnel and/or

TASK 2 -POWER PLANT FEASIBILITY DESIGN AND CONSTRUCTION COST
ESTIMATES
Description of Work Included:
This task will develop a feasibility design,construction and operational cost for building and
Feasibility Study
Donlin Creek Mine Interim Power Supply
operating a 40-45 MW low speed multi-barge mounted diesel power plant to supply the electric
power and energy needs of the Donlin Creek mine.Part I of the Calista Region Energy Needs Study
suggest that a mine load of 40+MW would most economically served from a power plant located
at Bethel rather than at Crooked Creek.Therefore,the primarily focus of this study will be to
evaluate the feasibility of locating the power barges at Bethel (85-90%effort)with secondary effort
(10-15%)on evaluating the feasibility of locating the power barges at Crooked Creek.It is assumed
that any plant constructed to supply the power needs of the Donlin Creek mine will need to be
operational on or about the year 2008.A field trip has been made to the Bethel and Crooked Creek
area to identify a proposed location(s)for the power plant.
Under this task a feasibility level design will be prepared in sufficient detail to obtain construction
cost estimates accurate to within +15 percent of expected construction cost,which is typical of the
accuracy associated with feasibility level study.This will be accomplished by working closely with
and soliciting cost estimates from qualified material suppliers and construction contractors.
Since power costs are highly dependent on delivered diesel fuel costs,significant efforts will be
expended to identify available fuel sources and to accurately identify the cost of providing #1,#2
and #4 fuel to supply the power plant.
Using waste heat from the power plant to heat the fuel stored in the tank farm allowing the use of
lower cost #2 or perhaps #4 diesel fuels will be evaluated where deemed practicable.
TASK 3 -TANK FARM
Description of Work Included:
It is anticipated that a fuel oil tank farm facility,estimated to be in the range of 12 million gallons,

15%will be expended for evaluating facilities at Crooked Creek.The final storage capacity will be
determined as part of the study.Under this task a feasibility level design will be prepared in
sufficient detail to obtain construction cost estimates accurate to within +15 percent of expected
construction cost.This task will be completed in conjunction with Task 3,Exhibit A-1.
TASK 4 -POWER PLANT PERMITTING
Description of Work Included:
Prepare a preliminary listing of the required permits and licenses required for constructing and operating the power
plant(s)and fuel oil tank farm facilities.Contact appropriate Federal,State and local agencies to solicit their comments
and to insure that regulatory and institutional concerns are adequately and timely identified and given appropriate
consideration.Review comments provided by various agencies and suggest potential mitigation measures.85-90%of
