EXECUTIVE SUMMARY

This Proposal sets out to define the work that is required to undertake a Definitive Feasibility Study (DFS) for the development of the Boleo Copper Cobalt Project (the Project) in Baja California Sur, a State of Mexico. 




The document was prepared by BATEMAN, with input from a number of specialist Consultants in the following areas: 

·

Environmental

·

Geology 

·

Mining

·

Geotechnical Engineering

·

Infrastructure

·

Logistics

Upon commencement of the DFS, selection of the Consultants will take place based on the strength of their relevant experience and expertise.  The Consultants will work with BATEMAN to undertake the DFS, which BATEMAN will manage.  BATEMAN will also be responsible for mineral processing aspects of the study.  First Goldwater Resources (FGR), and their subsidiary Minera y Metalurgica del Boleo (MMB) will play a role in the Study via the involvement of certain key resources in co-ordination roles in Environmental, Geology & Mining and a consultation role in mineral processing.  

As currently envisaged the Project will produce approximately 45,000 tpa of copper cathode.  The nature of the cobalt and zinc products is not yet finalised and will depend upon the findings of some early metallurgical testwork, which has the potential to greatly enhance the overall Project economic outlook. A fallback position is likely to be the production of intermediate sulphate products, requiring further upgrade elsewhere.  




The DFS will cover aspects of the Project including geology and mining, geotechnical investigations and engineering, metallurgical testwork, mineral processing, infrastructure, logistics and environmental studies.  




The Project has a number of unique factors that drive the scope of the Study and influence the manner in which it will be undertaken.  These include:




·

The fact that a new, more simplified, process flowsheet has been developed in an effort to improve the Project's economic outlook.  The existing metallurgical testwork database was focused on validating the earlier more complex flowsheet, hence further batch and pilot test work is required to prove the new flowsheet.  (Note that a major assumption which affects both the Study Budget and Schedule is that the Process Development will proceed smoothly without significant changes of direction being required.)




·

The fact that the Project contemplates using seawater as process water in the 'front end' of the flowsheet as a result of an absence of a reliable fresh water source and the exorbitant cost of producing large volumes of desalinated and demineralised water.   














·

The fact that the plant throughput and, more importantly, the 'product type and mix' is not yet defined.  It is generally believed at this early stage that it is not economically viable or appropriate to produce three different metals on site.  The requirement to produce copper cathode on site is taken as given but intermediate product forms (eg sulphates) for the Cobalt and the Zinc may be more applicable given the proportions of these metals in the plant feed. 




·

The fact that there is no reliable source of power to the Project readily available.  This requires that all power requirements be catered for in the DFS through a combination of co-generation and the use of standby generators. 




·

The fact that the current concepts for the Port facility are very capital intensive and that an options study is required at an early stage in the program to explore more cost effective solutions before final concepts can be fixed.




·

The requirement that all sulphuric acid used on site will have to be produced in an on-site acid producing facility, using either sulphur or pyrite as the raw material.  Both the sulphur and the pyrite will need to be imported by sea.  As the choice of input material has not yet been determined an options study is required at an early stage in the program before the final concept can be fixed. Clearly this decision impacts the nature of the Port facility, and the size, nature and cost of the Acid Plant.




·

The fact that a novel underground mining method has been proposed in an effort to improve the Project economics and increase mining selectivity.   The method employs mechanised mining equipment and techniques but is as yet untested on this particular ore type, requiring that a test mining exercise be carried out as part of the DFS. 




·

The fact that the Project Resource interfaces with a proclaimed Mexican National Reserve.  The area to the north of the nearby town of Santa Rosalia has been proclaimed a Nature Reserve by the Mexican Government and although the Boleo Property is geographically situated within the Reserve, it was released from the Reserve as an Act of Government in 1991.




·

The fact that the Project will be developed in a seismically active area. This has implications for the design standards used in the engineering design and will impact the mining strategy.




Having regard for these and other features of the Project, an approach to the Study has been developed that defines the work in three phases:




·

Phase 1 – Data Collection and Options Study Phase.  This essentially involves environmental base line studies, geological drilling (if required), geotechnical drilling, bulk sampling, metallurgical testing and flowsheet development and the option studies relating to the Port and the Sulphuric Acid production.  At the end of Phase 1, the Project development concepts would be fixed.  Phase 1 has a duration of around 6 months.

·

Phase 2 – Engineering Design Phase.  This phase is essentially a production exercise, where the Project facilities are designed and quantified prior to cost estimating.  Phase 2 has a duration of around 4 months.






.. .












·

Phase 3 – Report Preparation Phase.  This phase involves cost estimating, financial analysis and report writing, editing and publishing of the DFS.  Phase 3 has a duration of around 4 months.

Based on a start date of 15th July 2004, the draft DFS report could be completed by the end of July 2005.  The critical path lies through the recovery of representative bulk samples, which are required for metallurgical testwork to determine processing performance, and tailings testwork to determine thickening characteristics.  This is followed by the Pilot Plant campaign and the generation of the Process Design Package which serves as the kick-off point for the Engineering Disciplines.  This is followed in turn by the Estimating activities followed by production of the Study Documentation. 




Although not on the critical path, the success or otherwise of test mining exercise becomes critical to the plan. 




BATEMAN have offered a Budget Price of US$6 365 220 (six million, three hundred and sixty five thousand, two hundred and twenty dollars US) as detailed in Section 8 of this Proposal.  This price is based on the currently defined scope of work and clarifications.  (Note that a major assumption in producing this Budget Estimate is that the process development will proceed smoothly without significant changes of direction being required.)




Management Procedures for use in the Study have been prepared and are provided as a separately bound addendum to this Proposal.  The Management Procedures can be found in the Study Implementation Plan (DMS Document no. ZAB406-00012).  




BATEMAN and the core Consultants are all available and ready to mobilise for an early July start to the DFS program to ensure final completion of the Study by the end of September 2005.

INTRODUCTION




The Boleo Copper Cobalt Project has been extensively studied and evaluated by others over the last 20 years.  




These studies utilised complex metallurgical flowsheets and processing methods to extract the copper, zinc and cobalt from the resource.  This, and other difficult engineering aspects, led to the Project being considered economically sub-marginal and interest was suspended in the Project for a period during which Optimum Project Services Ltd (Optimum) acquired the Project from International Curator Resources (ICR).  




In the third quarter of 2001, a Pre-Feasibility Study was prepared by BATEMAN Engineering Pty Ltd (BATEMAN), for Optimum, simplifying the process flowsheet and reducing the capital and operating costs.  This work was successfully completed in March 2002 and, although largely a 'desk-top' exercise, achieved its objectives of improving the economic outlook for the Project.  




A Definitive Feasibility Study (DFS) is now required to be completed for the Project.  If the Project exhibits satisfactory economic viability, the DFS will be used as the basis for acquiring equity partnership or raising project finance. 




In the interim, the ownership of the Boleo asset has changed and now resides with a public company listed on the Vancouver Stock Exchange called First Goldwater Resources (FGR) through its 100% owned Mexican subsidiary, Minera y Metalurgica del Boleo SA de CV (MMB).  MMB will be the vehicle through which further project development takes place. 




FGR, through MMB, have requested that BATEMAN submit a document outlining the methodology, resourcing, cost and duration of the proposed study.  In compiling this submission, BATEMAN is pleased to assist MMB realise the full potential of the Boleo Project through the following endeavours:

*

Provision of a detailed scope of works, itemised budget estimate and a schedule for the execution of the DFS;

*

The provision of key BATEMAN resources to execute the Study with a team experienced in copper/zinc/cobalt extraction plant design;

*

Identification of specialist expertise for consultation in particular areas of the Project; 

*

Provision of budget estimates for the review and revision of current concepts and designs by those specialist Consultants;

*

A commercial approach that demonstrates our commitment to the Boleo Copper Cobalt Project through the feasibility study and into the implementation of this project.




The Boleo DFS implementation will largely be co-ordinated from the BATEMAN Brisbane offices and will involve the efforts of a wide variety of Consultants and client team members from around the world.

2.1

PROJECT LOCATION




The Boleo property is located on the east coast of the State of Baja California Sur in Mexico -  adjacent to the town of Santa Rosalia.  Santa Rosalia has a population of about 10,000 people and services a large fishing fleet, fish processing facility and two open pit gypsum mines.  One of the gypsum mines is located about 6km north of the town and other 20km to the south, on a small island adjacent to the Baja.   The proposed plant site is approximately 5km to the north of Santa Rosalia. 




Refer to the location plan below.

2.2

PROJECT HISTORY




The Boleo district has been a large producer of copper for over 100 years.  Estimates suggest that in total almost 19 million tonnes of ore were mined and treated from the various mines at a grade of about 4% copper and an unknown cobalt content.  Production figures from the French company, Compagnie du Boleo indicate that just over 13 million tonnes averaging 4.8% copper were sent to the smelter between 1886 and 1947.  In 1948, the Mexican government took control of the property and modest mining by independent Mexican miners took place intermittently up to about 1985.






.. .












During the period 1964-1972, the Mexican government also adopted a leach-precipitation-flotation plant with limited success. As part of their strategy to encourage foreign investment, the Mexican government adopted a new Mining Law in 1991. One of the results of the new Mining Law was the release of the Boleo Property from the Mexican National Reserve.  The property was acquired by Terratech Environmental Corporation in 1991 and in early 1992, a purchase option agreement was entered into with International Curator Resources Limited.




These activities are summarised in the table below.




Table  - Boleo Mining History




		
	Date

	Activity


	1868-1885

	Mexican Miners mined 60,000 t of 24% Cu oxide ore.


	1885-1953

	Compagnie du Boleo mined 14.4 million t ore at 4.8% copper.


	1922

	Original Blast Furnaces replaced by Reverb & Converters 


	1953-1985

	CMSR mined & smelted 1.8 million t at 3.5% Cu.


	1962-1972

	CMSR processed 3 million tonnes of dumps through the Leach-Precipitation-Flotation plant at 2% Cu.


	1993

	International Curator exploration activities commenced.







A Pre-Feasibility Study was completed in 1997 by Fluor Daniel Wright (FDW) on behalf of International Curator Resources Ltd (ICR).




The FDW study detailed the development of a complex process flowsheet to produce copper, zinc and cobalt from the resource.  This, and other difficult engineering aspects, led to the Project being considered economically sub-marginal and interest was suspended in the Project.  Curator was unable to raise money for the development work leading to suspension of the Project.   Due to lack of [contractual] performance by ICR, the Project reverted to Terratech Environmental Corporation in March 2001.  Terratech Environmental Corporation thereby acquired 100% interest in Mintec.   




In the third quarter of 2001, Mintec retained BATEMAN to conduct a rework of the process aspects based on a simpler process flowsheet with the aim of reducing the capital and operating costs and project risks.  A Pre-Feasibility Study was subsequently prepared by BATEMAN for Optimum Project Services Ltd (Optimum) simplifying the process flowsheet and reducing the capital and operating costs.  This work was successfully completed in March 2002 and achieved its objectives of improving the economic outlook for the Project.  




In the interim, the ownership of the Boleo asset has changed and now resides with a public company listed on the Vancouver Stock Exchange called First Goldwater Resources (FGR) through their 100% owned Mexican subsidiary, Minera y Metalurgica del Boleo SA de CV (MMB).

DEFINITIVE FEASIBILITY STUDY




3.1

INTRODUCTION

The primary objective of the Study is to produce a definitive feasibility study which, for the purposes of this document, means that all material aspects of the Project will be considered to a level that would allow banking institutions to base investment decisions on the Project.




In essence, the feasibility study documentation will demonstrate whether the Project is feasible, and if not, will highlight the fatal flaws.  In the absence of any fatal flaws, the feasibility study report will:




·

Describe the extent of an economic resource assessed to JORC (Joint Ore Reserve Committee of the AusIMM) standards or their Canadian Equivalent. 

·

Consider the following aspects of the Project and describe a viable strategy for each:

-

Mining;

-

Mineral Processing;

-

Tailings Deposition;

-

Infrastructure, including energy supplies, water supplies, transport and logistics; labour and accommodation;

-

Land tenure, mineral leases, permitting and licensing;

-

Environmental and socio-economic impact;

-

Project Development Plan




·

Estimate capital and operating costs for the Project to an accuracy of -5% +15%.

·

Provide input into a financial analysis of the Project (conducted by others).

·

Highlight the significant risks and outline mitigation strategies.




BATEMAN will sign off on the Definitive Feasibility Study and will execute the Scope of Work through:

*

A combination of direct provision of services, and

*

The management of services by third party Consultants.

BATEMAN Proposes to execute the Study from the established Brisbane office located at Level 8, 301 Coronation Drive, Milton, Brisbane, Queensland, Australia.  The Boleo DFS implementation will largely be co-ordinated from the BATEMAN Brisbane offices and will involve the efforts of a wide variety of Consultants and client team members from around the world.  The office is fully serviced and resourced to a level commensurate with that required of a leading edge engineering design and construction company.  




The office is located within a short walk of both short and long-term accommodation suitable for MMB, BATEMAN and consultant personnel who may be required to visit Brisbane during the course of the study.  In addition it is likely that MMB will take out a long-term lease on an apartment in the Zona Rosa area of Mexico City which will be used by Study personnel when in Mexico City.  






.. .












This section defines the Project scope and the services to be provided by BATEMAN as well as any services specifically excluded from BATEMAN's scope.







3.2

SCOPE OF PROJECT

The ultimate development concepts of the Project will evolve through the course of undertaking the DFS, however, for the purposes of planning, the scope of work most likely to be included as the Project Base Case envisages a greenfields development that involves:




·

Mining of the Boleo Copper Cobalt deposits in Baja California Sur, Mexico and processing the mined ore on site to produce 45 000 tpa of copper cathode and intermediate products of cobalt and zinc. 

·

An underground mining operation employing mechanised mining methods and equipment to produce around 2.2 million tpa of oxide ore as plant feed.  

·

A Processing Plant Facility, assumed to be located at the Cementario Site. The Processing Plant will most likely comprise an atmospheric leach followed by neutralisation, CCD, Copper SX and EW circuits.  The remainder of the circuit will be dictated by the nature of the cobalt and zinc products required, which may be in the form of intermediate sulphates.    The main plant outputs are the copper cathodes, possible intermediate forms of cobalt and zinc and the tailings.

·

Final product handling and storage prior to shipping. (The requirements here will be determined largely by the decision regarding final product forms for the cobalt & zinc.)

·

Tailings handling and disposal systems.  The Boleo Creek area, situated in close proximity to the Processing Plant, has been earmarked as the tailings disposal site.  The suitability of this site will need to be verified from an environmental and geotechnical perspective. 

·

Reagent handling & storage systems including a Sulphuric Acid Plant, a possible Hydrogen Sulphide Plant, limestone, quicklime, flocculants, diesel and other plant reagents.

·

Power supply systems to supply around 40-50 MW to the Project, which could come from a combination of co-generation and the use of diesel generator sets. 

·

Water supply systems, which currently envisage the use of seawater for process water in some of the Processing steps and the production of potable water through the employment of desalination and demineralisation plant.  There are no local river systems or aquifers available to the Project. 

·

Possible upgrading of some existing roads and the establishment of other new roads including the site access road. 

·

Investigation of alternatives to the currently proposed new wharf and berthing system to accommodate Handymax size ships (60,000 tonnes).  The ships deliver supplies and reagents to the Project, and transport copper cathode & intermediate forms of cobalt & zinc to overseas destinations. The current proposal is reportedly too capital intensive. 

·

Construction Camp and Temporary facilities.  The permanent operational workforce will be drawn from, and be housed in, the local town of Santa Rosalia. 






.. .

3.6

KEY ISSUES AND CONSTRAINTS




The following are the main issues and constraints that affect the scope and manner in which the feasibility study is conducted:




·

The schedule, which anticipates a start date of early July 2004 and completion of all study activities by 30th September 2005;




·

The level of accuracy required of the Study;




·

The process of obtaining approvals to undertake fieldwork, in particular the getting of metallurgical samples, in the Baja;




·

The fact that a new, more simplified, process flowsheet has been developed in an effort to improve the Project's economic outlook.  The existing metallurgical testwork database was focused on validating the earlier more complex flowsheet, hence further batch and pilot test work is required to prove the new flowsheet.  




·

The fact that the plant throughput and more importantly the 'product type and mix' is not yet defined.  It is widely accepted at this early stage that it is not economically viable to produce three different metals on site.  The requirement to produce copper cathode on site is taken as given but intermediate product forms (eg sulphates) for the Cobalt and the Zinc are probably more applicable given the proportions of these metals in the plant feed. This issue requires early resolution. 




·

The fact that the Project now contemplates using seawater as process water in the 'front end' of the flowsheet as a result of an absence of a reliable fresh water source and the exorbitant cost of producing large volumes of desalinated and demineralised water.   









.. .















·

The fact that there is no reliable source of power to the Project readily available.  This requires that all power requirements be catered for in the DFS through a combination of co-generation and the use of standby generators. 




·

The fact that the current concepts for the Port facility are capital intensive and that an options study is required at an early stage in the program to explore more cost effective solutions before final concepts can be fixed.  (The current concept for the Port takes the form of a 700 m long jetty terminating at the 17m depth iso-line.  The facility would be for self-loading and unloading vessels, carrying sulphur, diesel and other raw materials.  Sulphur would subsequently be conveyed to a storage bunker close to the plant site.)




·

The requirement that all sulphuric acid used on site will have to be produced in an on-site acid producing facility, using either sulphur or pyrite as the raw material.  Both the sulphur and the pyrite will need to be imported by sea.  As the choice of input material has not yet been determined an options study is required at an early stage in the program before the final concept can be fixed. Clearly this decision impacts the nature of the Port facility.




·

The fact that a novel underground mining method has been proposed in an effort to improve the Project economics.   The method employs mechanised mining equipment and techniques but is as yet untested on this particular ore type requiring that a test mining exercise be carried out as part of the DFS. 




·

The fact that the Project Resource interfaces with a proclaimed Mexican National Reserve.  The area to the north of the nearby town of Santa Rosalia has been proclaimed a Nature Reserve by the Mexican Government and although the Boleo Property is geographically situated within the Reserve, it was released from the Reserve as an Act of Government in 1991.




Each of the above issues impacts the Study in a different way.  Certain of the issues have considerable bearing on the economic viability of the Project and if not adequately resolved provide significant risk to the further development of the Project.  Early resolution of certain issues and convergence of general approach is therefore critical to the Project schedule being achieved.

3.7

PROPOSED APPROACH




In addition to the above unique key issues and constraints many of aspects of the Project need to be revisited during the DFS.   In line with this intent, proposals have been solicited from selected Consultants and engineers for specialist disciplines of work covering the following activities:




·

Review the current designs and allowances, 

·

Identify inadequacies & sub-optimal proposals and concepts, 

·

Conduct options studies & trade-off studies where required (which will include design and costing components), 

·

Provide documentation suitable for inclusion in the DFS.




 Having regard for these and other features of the Project, an approach to the Study has been developed that defines the work in three phases:




·

Phase 1 – Data Collection and Options Study Phase.  This essentially involves environmental base line studies, geological drilling (if required), geotechnical drilling, bulk sampling, metallurgical testing and flowsheet development and the option studies relating to the Port and the Sulphuric Acid production.  At the end of Phase 1, the Project development concepts would be fixed.  Phase 1 has a duration of around 6 months,

·

Phase 2 – Engineering Design Phase.  This phase is essentially a production exercise, where the Project facilities are designed and quantified prior to cost estimating.  Phase 2 has a duration of around 4 months.

·

Phase 3 – Report Preparation Phase.  This phase involves cost estimating, financial analysis and report writing, editing and publishing of the DFS.  Phase 3 has a duration of around 4 months.

3.7.1

PHASE 1 – DATA COLLECTION AND OPTION STUDY PHASE

The focus of Phase 1 is to get the field programs underway as early as possible so that the base information that will allow the Study to progress can be gathered.  The priority activities are:




·

To confirm the sites for the main project facilities,

·

To commence the geotechnical drilling programs,

·

To recover a bulk sample of representative ore, 

·

To conduct metallurgical and tailings testing,

·

To commence the environmental field program.

The following activities are planned for Phase 1:




·

The DFS will commence with a formal kick-off meeting involving all of the main players immediately after BATEMAN is appointed and contracts are executed by all parties.  The purpose of the kick-off meeting will be to establish a common focus, identify and understand major constraints, confirm the overall project scope, establish and agree major reference data, establish and plan priorities for Phase 1 and confirm overall DFS schedule.  It is recommended that major reference maps providing details of the Boleo tenements are made available prior to kick-off.  It is proposed that the kick-off meeting be held in Mexico City followed by site inspections / briefings (if required) and commencement of the Phase 1 work.  The kick-off meeting, detailed team briefings and site visit will involve the core team and others as required and approved. 














·

Source and obtain all existing project information not obtained prior to kick-off including:

-

Existing survey data

-

Previous drilling information

-

Previous sampling and assay logs

-

Legislation procedures

-

Access procedures 

-

Lease information

-

All data from previous studies




·

Call tenders and award contracts for:

-

Site survey (both ground and aerial) – if required

-

Drilling contractor  - Geotechnical Drilling

-

Laboratory and pilot testwork.

-

Site Infrastructure Review and Options Study

·

On the basis of the sites selected, plan a geotechnical drilling program and commence fieldwork.  Appoint a Geotechnical Consultant, undertake geotechnical evaluation studies and commence supplying geotechnical design information to the engineers for incorporation into designs for the Project facilities.

·

Commence resource modelling and mine planning.

·

On the basis of previous drilling programs obtain representative (approximately 45 tonnes of Manto #3 and 5 tonnes of Manto #1 High Acid Consuming Ore) bulk samples of ore from the orebody and arrange to ship the ore to an offshore laboratory for testing.

·

Carry out the metallurgical testwork program including bench scale, variability and pilot plant operation on which to base the process plant design criteria.  (Note that a major assumption which affects both the Study Budget and Schedule is that the Process Development will proceed smoothly without significant changes of direction being required.)

·

Prepare the process design for the processing plant and develop plant design criteria, flowsheets and mass and energy balance.

·

Following the completion of metallurgical testing, carry out testing of tailings materials for the purposes of CCD and thickener design and to determine deposition characteristics and performance.

·

Complete a water balance for the Project.

·

Commence the environmental investigation program as soon as possible.   The majority of the on-site work is expected to be environmental in nature.  The numerous baseline and socio-economic studies may require several visits by the sub consultant.  The baseline studies are understood to be 70% completed to the standard required for the EIS.  









.. .












·

Appoint an Environmental Consultant. The Consultant needs to become familiar with the data and procedures being used to gather the data.  The environmental work must comply with World Bank criteria.  Sign-off is thus required by a credible, registered person or organisation. 

A 3-week rolling horizon based upon the key dates will be used to establish clear lines of communications for the collection and passage of information.  This will be vital to the start-up of the field investigations and options studies, to ensure adequate data flows through for the continuing phases of the work in a seamless process.

3.7.2

PHASE 2 – ENGINEERING PHASE

This phase commences at the point that the main body of data has been collected from the field, laboratory and pilot plant testwork is essentially complete, the overall project development concepts have been established, and process flowsheet has been frozen.  




This phase is essentially a production exercise, in which the design of the facilities is undertaken, in sufficient detail to compile and support the estimates at the required level of accuracy and to demonstrate project viability.




In undertaking the work, BATEMAN will manage the process in order to:




·

Provide a safe operating environment.

·

Provide facilities that are fit for purpose.

·

Deliver value for money.




The main activities planned for this phase are:




·

Complete resource modelling, resource estimation, mine planning and design for the orebody.

·

Complete Process and Engineering Criticality Analyses before undertaking engineering design.

·

Complete engineering design and plant layouts in sufficient detail for estimating purposes and prepare materials takeoffs in all major areas.  

·

Complete or manage via Consultants or vendors the definition or design of major project infrastructure including Port Facilities, Power Supply, Water Supply, Major Roads, Communications, Buildings, Change-house, Laboratory, Security Facilities, Workshops   and Accommodation Facilities.

·

Prepare technical documentation and issue enquiries for all major equipment for the purposes of developing the capital and operating cost estimate.

·

Prepare scopes of work for 'packaged' plants for issue to external specialists for turnkey prices on such items as:

-

Acid Plant

-

Power Station

-

Hydrogen Sulphide Plant

-

Others, as required.









.. .












·

Commence capital and operating cost estimates.

·

Prepare a Project Description document suitable for use as the basis for developing the EIS, if required.

·

Undertake technical audits throughout the design process.




3.7.3

PHASE 3 - REPORT PREPARATION PHASE

During and from the preceding phases, approved data will flow to form the Report Preparation Phase of the study, which incorporates the following activities:




·

Capital and operating cost estimates,

·

Financial analysis – by others,

·

Technical audits,

·

Draft DFS report publication,

·

Report review and editing,

·

Report publication.

The main emphasis will be the final compilation of the estimates and financial analysis, the overall planning for the Implementation stage of the Project together with sign-off and presentation of the draft DFS report by early August 2005, assuming a 15th July 2004 start.




External audits will have been completed and incorporated into the documentation.




3.7.4

MAJOR REVIEW POINTS

A number of major reviews have been scheduled, during which MMB will have the opportunity to conduct a comprehensive review of study direction and progress.  Major reviews have been scheduled to take place around the following dates:




·

30 November 2004, which is approximately mid way through Phase 1 at a time when many of the options studies will have been completed and most of the fieldwork well advanced. 

·

2 February 2005, which is timed for the end of Phase 1 at which time most of the fieldwork will have been completed (except environmental), as will metallurgical testing, and the process plant design flowsheet will have been developed along with the Project mass, energy and water balance.

·

End May 2005, which is timed to coincide with the completion of the engineering design phase.

It is proposed that the major reviews can be conducted in either Australia, Mexico City or Vancouver depending upon which location makes the most sense for the participants.  For example the first review should probably take place in Mexico City as it will largely involve Consultants from Mexico or the USA.  Reviews 2 and 3 should probably take place in either Brisbane, where the bulk of the documentation will be at that time, but could equally take place in Vancouver where a greater client involvement will be possible.

STUDY ORGANISATION




4.1

GENERAL




While all the unit operations in the new flowsheet utilise known technology and are based on commercially operating plants, the existing test work database was focused on validating the earlier more complex flowsheet, hence further batch and pilot test work is required to prove the new flowsheet.  A batch and pilot test work program for the validation of the proposed DFS has been incorporated in this proposal to be undertaken as part of the Study.




In addition many of the non-Metallurgical aspects of the Project need to be revisited during the DFS.   In line with this intent proposals have been solicited from selected Consultants and engineers for specialist disciplines of work covering the following activities:




·

Review the current designs and allowances, 

·

Identify inadequacies & sub-optimal proposals and concepts, 

·

Conduct options studies & trade-off studies where required (which will include design and costing components), 

·

Provide documentation suitable for inclusion in the DFS.




These non-Metallurgical aspects include:




·

Environmental,

·

Geological,

·

Geotechnical,

·

Mining,

·

Infrastructure, and

·

Logistics.

It can be seen that consultant and contractor input to the Study is a significant proportion of the scope of work and this is reflected in the proportioning of costs – see Section 8 of this report for details.

As part of earlier proposals to Optimum, BATEMAN canvassed pre-qualified major consulting companies in order to identify Consultants that had the expertise and experience required to support BATEMAN during the completion of the DFS.  Potential Consultants were issued with a Consultant's Briefing document and selected supporting project documentation to enable them to prepare proposals.

Subsequent to client discussions in late May 2005 an effort was made to increase the Mexican content of the Study by involving a greater component of Mexican companies.  In early June 2004 additional Consultants were issued with a Consultant's Briefing document and selected supporting project documentation to enable them to prepare proposals. 

















The following Consultants submitted draft proposals for the elements of the work for which they considered themselves qualified:

		
	·

CAM – Mexico City

	Environmental


	·

SRK – Brisbane

	Geology, Mining, Geotechnical, Hydro geological, Environmental


	·

AMDAD – Brisbane

	Mining


	·

III SA de CV – Mexico City

	Infrastructure and Logistics Review


	·

Uhde-Jacobs – Mexico City

	Infrastructure and Logistics Review


	·

Maunsell

	Infrastructure and Logistics Review


	·

AARL – Johannesburg

	Process Testwork & Piloting


	·

Lakefield Oretest  - Perth

	Process Testwork & Piloting







BATEMAN, with assistance from David Dreisinger, are also conducting discussions with the CSIRO in Perth with a view to getting their input on a potentially critical aspect of the flowsheet. We are currently awaiting an "in principle umbrella commercial/technical proposal" for working together under a non-exclusive arrangement before we proceed with targeted testwork.

Once the Study commences a number of Consultants will be selected to assist with the development of the Study.  The Consultants will be evaluated against the following selection criteria, where applicable:

·

Quality and availability of their team.

·

Experience in copper cobalt projects.

·

Experience in Mexico.

·

Understanding of the Project and the important issues.

·

Flexibility of approach and ability to provide innovative thinking.

·

Ability to work in an integrated team.

·

Charge rates and ultimate cost.

·

Ability to meet the required study timetable.

·

Attitude to responsibility and liability.

It is proposed that these core Consultants will go forward to form the core team to undertake the DFS with BATEMAN after having been approved by MMB.

It is acknowledged that work has been ongoing since the completion of the PFS by ICR and that of BATEMAN in November 2001, and that Mexican and Canadian engineering firms have been involved with ongoing work for the duration that the Project has been under consideration. It is planned to utilise this experience and expertise wherever possible either in a direct manner or supervised by others working under the direction of BATEMAN.




Clearly, a significant amount of work has been conducted on the Project to date and it is proposed to review this work in the Data Review and Options Study Phase referred to as Phase 1.  It is expected that some aspects of the Project will require more work than others however the level of the available documentation and standard of engineering or design on any works carried out to date needs to be assessed against the standards required for a DFS.

















A key outcome of the review process will be a clear understanding of what data is held, the reliability and adequacy of the data for the purpose intended, an understanding of what deficiencies exist and of those areas where additional engineering or investigation is required to complete the DFS.  




After the initial review period, the Consultants will be required to produce an accurate cost and study schedule for input to the Project Budget and Project Schedule. 




Where applicable, site visits will be undertaken but this requirement will be purely needs driven.  Review in certain disciplines may be carried out as a 'desk-top' exercise provided that the appropriate data (electronic or hard copy) can be made available.   




The review may involve meetings with selected Consultants and experts currently or previously involved in the Project.  These may include Mexican or Canadian based specialists.  




Note that one of the main purposes of Phase 1 is to gain a clear understanding of what data is held, make a judgement on the adequacy of the information for DFS purposes and determine those areas where re-engineering, additional engineering or additional investigation are required with the view to defining a more precise budget and study scope.  




The purpose of the work is to enable a more precise budget and study scope to be defined and it is not intended that this stage of work shall be directly for the preparation of the DFS.  It is anticipated that the data collection and review work in Phase 1 would generally be completed within 4-6 weeks of appointing, and contracting with, the appropriate Consultant.  Options studies, should they be required, will flow from this review process.




With that in mind the essential elements of each of the main work package areas are as follows:  




4.2

CONSULTANT SCOPES OF WORK




4.2.1

4.2.2

GEOLOGY AND RESOURCE ESTIMATION

For the purposes of this budget estimate it has been assumed that no additional geological resource drilling will be required for DFS purposes.  However, some metallurgical sample collection, involving drilling and some geotechnical drilling is required.  




It is further assumed that the geology work will involve an audit of the processes used in deriving the data generated, re-modelling to validate the resource estimates and a check of the variography to ensure drilling has indeed been done to a level appropriate for the reporting of a DFS.  Details of the geology program are presented below:




The Geology and Resource Estimate services will be executed by a competent consultant geologist and will include:

*

Sample preparation techniques and assay methodology;

*

Review of the diamond drill core including logging, recovery, storage, sample selection and data recording (including validation);

*

Review assaying methods and standards used;

*

Review sample preparation;

*

Review of the primary controls on mineralisation and regional/local geology in particular;

*

Review mapping and survey standards utilised;

*

Review variography and geostatistics to ensure reporting or resource estimates meet with JORC standards or the Canadian equivalent;









.. .












*

Validate the resources estimates. This is expected to require generation of an independent model by loading validated data into a geological modelling system  (Note that an Underground Resource Calculation and Review has recently been conducted by Dave Mehner – a Professional Geologist operating out of Vancouver.);

*

Identify sources of material in the region suitable for construction; and

*

Provide recommendations for any further Geological Investigation, if required.




BATEMAN shall provide the following services:




*

Facilitation of Consultants' tender briefing meeting;

*

Assistance in contract formation between MMB and the consultant; (Note that the Consultants shall be contracted directly with MMB.)

*

Interface between geologist and BATEMAN metallurgists to validate representative samples for metallurgical testwork (bench scale & pilot);

*

Supply of operating costs to establish cut-off grade and other process related information to the Consultant Geologist;

*

Commercial and performance management of the Consultant Geologist on behalf of MMB; and 

*

Monthly progress review and reporting to MMB.

MMB shall be responsible for:




*

Co-ordination of the Consultant Geologist by the MMB Project Geologist

*

Payment of approved progress claims; and

*

Attending progress and technical review meetings.




4.2.3

GEOTECHNICAL ENGINEERING/HYDROLOGY AND HYDROGEOLOGY

It is understood that insufficient work suitable for a DFS has been undertaken in the past.   




Mining of the deposit may involve a combination of open pit (Manto #1) and underground workings (Manto #3) and, perhaps initially, only high grade underground workings in Manto #3.  The scope of work that must be addressed in a Geotechnical Study for Definitive Feasibility purposes has been broken into different domains and includes:




4.2.4

OPEN PIT GEOTECH:

1.

A description of the geotechnical and geological models, identification of the geotechnical domains;

2.

Identification of the kinematically possible slope failure mechanisms incorporating seismicity of the area and hydrogeology aspects;

3.

Deterministic and probabilistic slope stability analyses;









.. .












4.

Recommendations of pit slope designs, slope drainage, drill and blast design;

5.

Comment on excavation techniques, trafficability, comminution characteristics (hardness etc for crushing and grinding) and materials handling characteristics; and

6.

Risk assessment;

7.

Waste Dump design criteria.

4.2.5

UNDERGROUND MINING GEOTECH:

1.

A description of the geotechnical and geological models, identification of the geotechnical domains;

2.

Identification of the kinematically possible slope failure mechanisms incorporating seismicity of the area and hydrogeology aspects;

3.

Comment on excavation techniques, trafficability, comminution characteristics (hardness etc for crushing and grinding) and materials handling characteristics; and

4.

Risk assessment.

4.2.6

TAILINGS DISPOSAL GEOTECH:

1.

Site assessment.  The Boleo Creek is currently proposed as the tailings disposal site.  

2.

Site evaluation/analyses.  The Boleo Creek is currently proposed as the tailings disposal site.  As such investigative drilling of at least one site is required.  Allowances have been made for drilling for tailings geotechnical investigation.

3.

Retention dam design.  This work is believed to be incomplete and there is potential to use mine waste materials; and

4.

Hydrogeological assessment with regards to seepage and contaminants entering the ground water systems.  Whilst the region is extremely arid, the EIS must take cognisance of the hydrology and hydrogeology aspects.  The Consultant Geologist would again work with CAM for the data gathering.  Once the data has been gathered, groundwater modelling will be undertaken and close interaction is essential with the environmental scientists for the tailings disposal design.

4.2.7

INFRASTRUCTURE GEOTECH – ON SITE




1.

Footings and foundation engineering for structures;

2.

Geotechnical engineering for site roads, and

3.

Identification of suitable building materials for roads, (if applicable) the rock wall emplacement for the port and concrete construction.









.. .












4.2.8

INFRASTRUCTURE GEOTECH - OFF SITE:

1.

Sulphur conveyance and handling.  Other raw materials and diesel supplied to the Project and their handling/storage; and

2.

Site access roads.

Note that the above work required is for the DFS and is not for construction purposes. 




Clearly, only an estimate of cost can be provided at this stage and Phase 1 of the DFS is required to provide better definition.  The work would be performed under the guidance of the Consulting Geologist, using a Mexican company for both the drilling and the subsequent testwork.




4.2.9

MINING

An underground operation producing high-grade ore early in the mine life may improve the Project's economics.  MMB have proposed the use of continuous mining equipment in an underground mining scenario.  The concept has shown promise in addressing access to the high-grade zones of the Boleo deposit. The mining consultant will need to further develop and work with this concept.  Due to the risks inherent in this decision a full scale on-site trial of this method of underground mining is proposed as part of the DFS and will take place in Jan 2005




The development of the mining component of the DFS will include:

*

Conduct a conceptual mining options study to determine the potential for different mining strategies including the incorporation of early underground mining methods.  Underground methods could include decline, adit or shaft entry using continuous miners to recover the ore;

*

Review geotechnical design parameters and cost assumptions for mine optimisation and mine design.  Conceptual designs must be devised and cost models generated;

*

Development of mine design criteria;

*

Review the mineral resources and examine ore geometries and ore types at various cut-offs;

*

Apply mine optimisation methods based on block models generated by the consultant geologist; 

*

Prepare mine designs including development and production plans;

*

Prepare mobile equipment schedules and technical specifications for development, production and support equipment;

*

Prepare mining reserve computation and dilution provision;

*

Prepare mining schedules for development and production;

*

Produce capital and operating costs for mining component;

*

Prepare new haul road designs and general mine layout work; and

*

Waste dump design.









.. .












BATEMAN shall provide the following services:




*

Facilitation for Consultants' tender meeting;

*

Assistance in contract formation between MMB and the consultant; (Note that the Consultants shall be contracted directly with MMB.)

*

Commercial and performance management of the consultant on behalf of Mintec; 

*

Monthly progress review and reporting;

*

Review of documentation for suitability for inclusion in the final document.




MMB shall be responsible for:




*

Co-ordination of the Consultant Mining Engineer by the MMB Project Geologist;

*

Payment of approved progress claims; and

*

Attending progress and technical review meetings.




4.2.10

ENVIRONMENT

The majority of the on-site work component is expected to be of an environmental nature.  The baseline and socio-economic studies may require several visits to site and prolonged periods of observation and data gathering.  The baseline studies are understood to be 70% completed to the standard required for the EIS. To ensure continuity and efficiency on the Project, Corporacion Ambiental de Mexico (CAM) have been retained to conduct the Environmental Study. They have a long history on the Project. 




It is intended that an Environmental Consultant to appointed, probably out of the USA or Canada, with the ability to sign-off on the environmental work conducted by CAM.  The Consultant will need to become familiar with the data and procedures being used to gather the data, and is required to ensure that sign-off formalities and protocols are conducted by a credible, registered person. The environmental work must comply with World Bank criteria.




In addition Manuel Moreno, a Mexico City based Consultant of impeccable reputation will monitor the performance of CAM and assist with the overall environmental strategy and direction. 




The development of the environmental component of the DFS will largely be executed from within Mexico and will include:









.. .












*

Completion of the base line study. It was recognised that a majority of the baseline study has already been conducted and it was therefore recommended that the firm previously involved, namely CAM, was best placed to complete this work.  

*

CAM & Manuel Moreno would initially review the work done to date and ascertain the remaining work required for the DFS.  The appointed Consultant would work with CAM and Mr. Moreno to complete the Study and sign-off on the end result;

*

Conduct hydrological and hydrogeological studies.  The geotechnical engineers will predominantly carry out these studies.  However, a close interaction is essential with the environmental scientists.  Particular reference must be made to any acid mine drainage issues and net acid generating potential.  This aspect will be undertaken in conjunction with the geotechnical engineering work on ground water.  Note that Golders previously conducted a study of this aspect and considered that there was low potential for the generation of acid generation;

*

Completion of a socio-economic impact assessment;

*

Completion of noise, visuals and dust/emissions reports;

*

Completion of an EIS/EIA suitable for submission to the appropriate authorities and baseline studies in support of the EIA have been deferred until the detailed engineering design of the Project is undertaken;

*

Determine rehabilitation plan and schedule;

*

Mine closure costs;

*

Prepare a preliminary environmental plan.

*

The environmental work must comply with World Bank criteria.

BATEMAN shall provide the following services:




*

Compilation and issue of tenders to selected Consultants, if required, and provide a technical and commercial evaluation of such tenders;

*

Assistance in contract formation between MMB and the consultant;  (Note that the Consultant shall be contracted to MMB.)

*

Commercial and performance management of the consultant on behalf MMB;

*

Monthly progress review reporting;

*

Preview of documentation for suitability for inclusion in the final document.

MMB shall be responsible for:




*

Co-ordination of the Environmental Consultant by the MMB Project Geologist;

*

Payments of approved progress claims; and

*

Attending progress and technical review meetings.






.. .












4.2.11

METALLURGY 




BATEMAN will provide the following services:




4.2.12

LABORATORY TESTWORK

*

Development of a metallurgical test work program.  This shall initially include assessment of a number of composites in a batch program preceding the proposed pilot plant program.  The focus of the batch test work program on these composites will be definition of operating parameters for unit operations not previously tested that are now included in the revised flow sheet.  This work will also allow clearer definition of the subsequent pilot plant requirements.

*

The composite of ore for piloting and the batch composites shall be based upon the scheduled results of mining engineering and mine optimisation work to determine the ore mix that can be expected over the life of the Project.  In this way the test work will be conducted on representative ore types and mixes in particular the ore types likely to be encountered during the "initial project payback period'.  Consideration will be given to production of a small number of different composites representing sequential time frames in the mining schedule to allow the plant design to cater for longer term variability in the ore supplied to the plant, and enable decisions to be made as to what design allowances will be made in this area.

A preliminary test work scope has been developed by BATEMAN and D Dreisinger.  This has been costed by two commercial laboratories to provide a basis for the costs presented in this proposal.  The preferred proposal at this stage in the development of the Project is the submission from AARL in Johannesburg, South Africa.  These costs have been updated in Jan 2004 and appear in the Budget Estimate.   For the DFS these budget costs will need to be firmed up and this can only take place once the testwork scope is completely defined. 

BATEMAN activities include the following:

*

Compilation and issue of tender for laboratory test work;

*

Technical and commercial evaluation of tenders;

*

Assistance in contract formation between MMB and the service providers;

*

Management, audit and review of metallurgical test work;

*

Compilation and analyses of results; and

*

Reporting for DFS purposes.












.. .












Thereafter a period of flowsheet development will take place, during which a preferred flowsheet is taken forward to the Process Plant Design Phase of the DFS level of definition & engineering. 




4.2.13

FLOWSHEET DEVELOPMENT




*

Validation and selection of an appropriate flow sheet;

*

Collate all test work results and formulate preliminary design criteria;

*

Development of mass and heat balances;

*

Document for DFS purposes.




Note that it has been assumed that BATEMAN have reviewed the metallurgy and process engineering sufficiently during the Pre-Feasibility period and that a specialist site visit is not necessary.  The initial site inspection by the BATEMAN Study Manager conducted on 21/22 May 2004 is considered adequate for this purpose.




4.2.14

PROCESS PLANT DESIGN

BATEMAN will undertake the following to an appropriate level of definition & engineering commensurate with a Definitive Feasibility Study:

*

Development of design criteria for the selected flowsheet;

*

Optimise the Product Mix;

*

Develop mass, water and heat balances for the system;

*

Prepare process flow diagrams;

*

Develop a simulation model for the chosen option to confirm process design and aid training;

*

Prepare site layout plans for the chosen option;

*

Plan and co-ordinate geotechnical drilling and test work for the processing plant, process facilities and infrastructure and evaluate results;

*

Prepare preliminary P &ID's, equipment list, equipment data sheets, instrumentation list, piping line list and valve list;

*

Prepare general arrangement drawings, plans, sections and sketches sufficient for estimation of bulk quantities;

*

Estimate I/O and control loops, instrument list and motor list;

*

Prepare a listing of installed power, maximum demand and running loads;

*

Prepare preliminary cable schedules;

*

Prepare technical specifications of all major items of equipment in sufficient detail to obtain estimate accuracy's required;









.. .












*

Estimate first fills as required;

*

Estimate spares including insurance spares; 

*

Prepare HV reticulation and tie up with site grid;

*

Allow for plant stormwater drainage;

*

Determine start up and control strategy;

*

Prepare a manning schedule; and

*

Prepare operating consumables quantities.




4.2.15

PROJECT INFRASTRUCTURE REVIEW




Support infrastructure will comply with Mexican standards and shall be provided in line with standard practise in Mexico.  It therefore makes sense to utilise a Mexican Engineering company in this role.  




A review of all of the infrastructure facilities required for the production outputs is required. The review will address the adequacy of the following:

*

The design for conditions including seismic and climatic conditions;

*

The capacity of the item under review to meet the production outputs;

*

The work for a DFS, and

*

The cost estimates for the task.




4.2.16

ON-SITE INFRASTRUCTURE

A review shall be conducted of the site selection assessments with respect to revised proposed plant and mining operations.




Planning assumptions for Ancillary Buildings should be reviewed. These include:




·

Guardhouse

·

Warehouse

·

Change-house and canteen

·

Laboratory

·

In all reviews the costs would be reviewed and updated accordingly. Specific areas of review include:









.. .












4.2.17

WATER SUPPLY

Based on our current understanding of the process, the process water in the first half of the plant flowsheet is expected to be seawater.  Thereafter the process will use fresh water supplied from the desalination plant.  Potable water will also be supplied from the desalination plant.




The seawater and fresh water requirements for the new processing plant flowchart will be provided by BATEMAN.  This will include allowances for return water from tailings dams and requirements for dust control.  Potable and desalinated water estimates will be gained from manning lists and plant demand estimated by the consultant.  Design and documentation for fire and emergency water supply shall be provided.




The designs, costs and allowances for the water supplies will be reviewed, updated and documented.




4.2.18

ROADS

On site road designs shall be assessed for cost estimation, design adequacy and the application of the roads for the duty intended.  The assessment should also include an assessment of the local materials proposed for road construction.  This materials study shall be done in conjunction with the geotechnical engineer.




4.2.19

SULPHUR HANDLING AND STORAGE

Sulphur and raw materials handling and storage systems designs and cost estimates shall be reviewed updated and documented.  These facilities are expected to be retrofitted to the gypsum facility for out-loading gypsum through the port facility.  Refer to 4.9.10 Power Supply for reference to power plant study requirements.




4.2.20

FUEL HANDLING AND STORAGE

Diesel is designed to be stored in 2 x 2,000m3 tanks.  The capacity, design and cost estimation shall be reviewed, updated and documented.




4.2.21

SEWAGE AND WASTE DISPOSAL

The capacity, design and cost estimation shall be reviewed, updated and documented.




4.2.22

PLANT AREA DRAINAGE

The capacity, design and cost estimation of stormwater deviation channels shall be reviewed, updated and documented.




4.2.23

COMMUNICATIONS

Telephone, data transmission and radio communications allowance, designs, costs and technological suitability shall be reviewed with respect to capacity, design and cost updated and documented.









.. .












4.2.24

CONSTRUCTION PHASE

Review on site construction phase requirements including size and cost, temporary facilities and services, concrete batch plant, water and materials supply, maintenance facilities, office and change-rooms, power supply, communications, waste treatment and stores.  Mexican contractors are expected to be utilised.  Approximately 800 to 1,000 personnel will be required to construct the facility.




4.2.25

POWER SUPPLY

The plant power supply will be delivered primarily by co-generated power from the sulphur-burning-acid-plant, but will be supplemented by a diesel operated generating sets. The design calculations for the extent of co-generated power possible from the burning of either sulphur or pyrite need to be reviewed.




4.2.26

OFF SITE INFRASTRUCTURE

Port

The port facility needs a major review.  The current concepts for the Port facility are too capital intensive for the Project to bear and an options study is required at an early stage in the program to explore more cost effective solutions before final concepts can be fixed.  (The current concept for the Port takes the form of a 700 m long jetty terminating at the 17m depth iso-line.  The facility would be for self loading and unloading vessels, carrying sulphur, diesel and other raw materials.  Sulphur would be conveyed to a storage bunker close to the plant site.)




BATEMAN has assumed responsibility for the engineering, design and estimation of the raw materials delivery conveyor system from a discharge point on the pier to the plant storage facilities on site.  BATEMAN Materials Handling specialists are proposed for this work




Several options for transport of the sulphur are likely and these will be evaluated conceptually before undertaking detailed engineering and costing.  Capital cost may be less for some options but operating costs could be more and an economic decision is required to ascertain the best alternative.    




The work will include review and update of costs of the port facilities design, construction materials, capacity and cost estimates.




Access Roads to Plant and Site

The work will include review and update of the cost estimates accordingly.




Construction Camp

Although the majority of long term workers will be sourced from the town a construction camp will be required to house the peak levels of manning likely to be seen on site during the construction period.  




4.2.27

LOGISTICS REVIEW




The following represents the scope of work for this activity:




Raw materials supply is a key issue in the continuous successful operation of a plant and mining operation dependent upon those supplies.  









.. .















The logistics of providing bulk raw materials and consumables to the site need to be assessed as part of a detailed study to verify the operational assumptions and risks associated with current proposals for delivery and storage of these materials on site.  The focus will need to be on interrelationships between infrastructure, capital cost, operating cost and logistics planning. 




The Study should take account of usage rates for raw materials, options for delivery of the materials to site including shipment size and frequency, minimum inventory quantities and acceptable risk levels, and the cost associated with delivery and storage of the materials.




The work must include an assessment of the door to door supply chain for materials to be transported and stored on site including:




·

Process for consolidation & shipping of materials, including definition of pack type (dry bulk, liquid bulk, unitised, break bulk, containers);

·

Shipping arrangements – charter, contract of affreightment, liner shipping etc;

·

Materials handling needs;

·

Port site costs;

·

Wharf to mine transport costs;

·

Storage needs, quantities, type;

·

Risk assessment of the supply chain and where applicable

·

Permitting;

·

Governmental clearances;

·

Importation taxes.

The outcomes of the review should be presented in terms of cost per tonne and where applicable a Capex component should be included.  Qualitative assessments need to be made for each logistics system option identified.




The logistics report must present a series of recommendations on the provision of bulk raw materials and consumables to the site for consideration.  Once the delivery and storage requirements for each of the material types has been selected, facilities that meet the approved requirements must be configured for inclusion in the DFS.  




Consumption rates of all raw materials will be provided by BATEMAN.  




*

BATEMAN proposes to use a Mexican company to undertake the Logistics Review and Study contribution.

.  

4.2.28

MARKETING AND SALES ANALYSIS




On the client's instruction BATEMAN has made no allowances for the Marketing and Sales Analysis for the Project.  




MMB shall be responsible for the provision of the following:












.. .












*

Assessment of market supply and demand for the products from the Project;

*

Details of historical and forecast copper, cobalt and zinc prices;

*

Description of marketing strategy;

*

Philosophy of product transportation and handling; and

*

Provision of the key parameters to be set for financial evaluation purposes (eg. Selling Prices and battery limits that the market can sustain).




4.2.29

LEGAL MATTERS, LEGISLATION AND DUTY




MMB shall be responsible for all lease, legal, tenure and security of title issues associated with the Project.  MMB shall make available to BATEMAN all information pertaining to taxes, depreciation, royalties and other pertinent charges associated with the Project.




4.2.30

Prepare construction manning schedule;

*

Prepare a freight tonnage schedule by place of origin; and

*

Prepare an occupation health and safety plan.




4.2.31

CAPITAL COST ESTIMATE




Based on preliminary design and work scopes described above, BATEMAN will compile a project capital cost estimate for the DFS inclusive of:

*

A capital cost estimate with an accuracy of –5% +15% for the DFS;

*

A Sustaining Capital Schedule for mobile equipment and fixed plant replacement or expansion;

*

Estimates for indirect costs including: EPCM, temporary facilities, first fills, insurance, commissioning, duties and taxes;






.. .












*

A description of the estimate basis;

*

A capital cost estimate by breakdown by facilities, equipment items, domestic freight; overseas freight, direct labour, construction equipment, contractors installation costs, spare components, foreign currency components and exchange rates; and

*

Contingency assessment and allocation commensurate with estimate accuracy.




4.2.32

OPERATING COST ESTIMATE




BATEMAN will compile a project operating cost estimate inclusive of:

*

Operating cost estimates with and accuracy of –5% +15%;

*

Contingency assessment and allocation commensurate with estimate accuracy;

*

The costs for the operation of each facility including operating labour, maintenance labour, consumables, maintenance supplies and administration costs;

*

Descriptions of estimate basis; and

*

Estimate by operating area, sub area and commodity.




4.2.33

FINANCIAL EVALUATION




On the client's instruction BATEMAN has made no allowances for the generation of an economic model for the Project. 




It is expected that development of the model will be carried out by an independent consultant operating in close consultation with MMB.  A range of sensitivities should be conducted using the model as a base.  




An economic Risk Assessment should be performed on the model employing Monte Carlo simulation and probability information derived from discussions with MMB and the various experts contributing to the Project.  




Note that it is only required to evaluate the model for the major sensitivities such as selling price, escalation, exchange rates, operating costs and capital costs.  Typical results show the economic parameters such as IRR and NPV on a probability distribution "S" curve or bell curve or cash flow for the Project with one and two standard deviation halo lines.  This type of information enables investment decisions to be made with a better understanding of the probability of making and losing money on the Project.




The input data (e.g. the range of selling price and probability of achieving those prices) are key inputs and are best determined in consultation with MMB, BATEMAN and other experts with considered knowledge of the parameters.









.. .












4.2.34

PROJECT RISK ANALYSIS




BATEMAN, in conjunction with the various Consultants and MMB, will undertake a project risk analysis. This shall include quantitative economic risk analysis as described above.




4.2.35

FEASIBILITY STUDY DOCUMENT COMPILATION




BATEMAN will be responsible for assembling the DFS documentation as follows:

*

Incorporate studies carried out by Consultants including appropriate audit statements;

*

Review of the Executive Summary and other pertinent sections by a technical editor;

*

Preparation of a draft document for review by client personnel;

*

Management of the reproduction of copies of the DFS documentation.  The number of copies shall be agreed during the scoping study.

*

MMB will be responsible for the final approval of the document.




4.2.36

MANAGEMENT PROCEDURES




A preliminary Study Implementation Plan has been produced – see document  number ZAB406-00012 for detail.  This document contains important information relevant to all Study participants. 




BATEMAN Management Procedures are designed to cover the following subjects:




·

Study Set-up

·

Study Management

·

Planning and Scheduling

·

Estimating and Cost Control

·

Engineering

·

Contracts and Contract Administration

·

Construction Site Management

·

Purchasing, Expediting and Inspection

·

Commissioning

·

Accounting and Administration

·

Study Close-out

The following summarises some key aspects that are relevant to all participants involved in the study, particularly the core Consultants.




5.1

STUDY MANAGEMENT

5.1.1

AUTHORITY LEVELS

Authority to commit funds for the Study will be governed by a project-specific procedure.  Only the DFS Study Manager has the authority to approve and commit funds except for the Consultant Co-ordinators who each have the authority to make financial commitments limited to the capped budgets set for their respective scopes of work.  Any commitments that are outside the approved budget require specific approval of the DFS Study Manager.




5.1.2

AUDIT TRAILS

The final study will be the subject of review by independent third parties.  A number of external reviews are planned and reinforces the need for the Study documentation to be of highly auditable standard with easy traceability of all outcomes back to their source.




It is possible that the Study files will re-use some files from previous studies.  In order to keep all study documents together and to facilitate auditability, the relevant documents are to be copied over into the Study files and marked with appropriate notes.




5.1.3

INTERFACES AND COMMUNICATIONS

The fact that there are a number of participants in the Study means that there are many interfaces.  BATEMAN as the managers of the Study are responsible for the effective management of the inter-relationships and interfaces between the parties involved.












.. .












In order to achieve the desired outcomes, the Study will be conducted as an integrated team involving all participants and stakeholders with formal lines of communication and responsibilities as shown in the organisation chart.  The team will meet regularly throughout the Study to exchange information, report progress, and discuss and resolve issues.  With regard to communications:




·

Team members at all levels will be encouraged to communicate directly with their counterparts in order to enable them to progress their work efficiently and effectively.

·

However, while frequent, informal communications are encouraged, all formal communications, (i.e. those that have the potential to significantly influence study outcomes), will be in writing.

·

All formal written study communications will be channelled through Consultant Co-ordinators.

·

The Consultant Co-ordinators will be responsible for conveying formal communications to BATEMAN and appropriate people internally and externally as quickly as possible; 

·

BATEMAN will schedule regular meetings to bring the Consultant Co-ordinators together to report on progress and resolve issues that might arise.

·

The Consultant Co-ordinators will schedule regular internal meetings within their respective organisations for the same purpose, enabling reporting and issues to be 'rolled up' to BATEMAN quickly.

·

All telephone discussions that have the potential to influence the DFS outcome are to be recorded and if significant brought to the attention of the DFS Study Manager.

5.1.4

MEETINGS

A regular meeting schedule will be established at project kick-off, which will include as a minimum:




·

Internal co-ordination meetings, involving the BATEMAN study team on a routine, weekly basis throughout the study. 

·

Consultant interface and project review meetings, involving Consultant Co-ordinators from the various sub-Consultants on a routine, weekly basis throughout the study.

There will also be other meetings that will be conducted in the course of the study, some on a routine basis, and others ad-hoc around specific issues.  All meetings will be minuted, with minutes circulated in English within three working days.  MMB will be invited to attend all meetings. 




5.1.5

REPORTING

BATEMAN will compile a monthly report for issue to MMB on a routine basis, with reports being issued as follows:




·

BATEMAN's reports will be issued to MMB in English by the 12th day of each month.

·

Sub-Consultant’s reports will be issued to BATEMAN by the 9th of each month in English.

·

Timesheet summaries for all Consultants showing hours consumed for the previous period will be issued to BATEMAN each fortnight on Wednesdays.  The summaries will compare actual hours against budget and provide a forecast based on the estimated work outstanding.

·

Reports will be set out according to an agreed format.  The BATEMAN report will cover all sub consultants, whose reports will be structured in such a way as to streamline assembly of the report to MMB.






.. .












5.1.6

WORK BREAKDOWN STRUCTURE

The proposed WBS for the Study is based on the major areas of the process plant, infrastructure and utilities describing the Project and will be structured under the following major headings, each of which will be a major area of the Project as shown in the Study Report:




·

0000

Mining and Geology

·

1000

Process Plant

·

2000

Support Services

·

3000

Support Facilities

·

4000

Infrastructure

·

5000

Temporary Construction Facilities

·

6000

Indirect Costs

·

7000

Pre-production Costs

·

8000

Escalation and Contingency

·

9000

Other Costs and Expenses

A WBS for the Project implementation phase, similar to that shown above, will be developed in more detail during the Study and used for project implementation planning and estimating purposes.




5.1.7

COMMON SYSTEMS 

To maintain compatibility of software systems, the following software will be used on the study:




·

Microsoft Word for all word processing requirements

·

Microsoft Excel for spreadsheets

·

Microsoft Project for project planning

·

AutoCAD Version 14 for drafting

5.1.8

OWNERSHIP OF DOCUMENTS

All documents produced as a part of the deliverables of the Study will become the property of MMB as deliverables of the Study.




5.2

PROJECT QUALITY PLAN

A Study Quality Plan (SQP), defining the procedures to be used to control project execution, the Project organisation, specific client requirements, and approved departures from the Standard Practice System, will be prepared for the Study.  




Where the SQP also covers topics covered here, the SQP takes precedence.




Sub-consultants will be required to submit Study Quality Plans for their scopes of work.




5.2.1

STUDY QUALITY AUDITS

A schedule of Quality Audits will be established at the outset of the study, which will:









.. .












·

Cover regular scheduled audits into document control, engineering, procurement and estimating;

·

Include audits of Sub consultants;

·

Provide for audits to involve the Project Quality Engineer and the relevant functional managers. 

5.2.2

DOCUMENT CONTROL

The Study will also be the subject of BATEMAN's Standard procedures with respect to document management, transmittals and emails.  The basic philosophy is that all documentation that is raised for the Study, whether it was generated during the Study or prior, belongs in the Study files as a correctly registered document.




5.2.3

CHANGE CONTROL

BATEMAN's standard Change Control Procedure will apply to work undertaken in the Study, including work undertaken by sub consultants:




·

Any changes in scope will be the subject of a Change Alert, which will bring the matter to the attention of the BATEMAN Study Manager.

·

If the change has a cost or schedule impact then it will be raised as a Scope Change Notice and submitted to MMB for approval along with an explanation of the circumstances, the cost and schedule impact.

·

Additional work or charges are not authorised without MMB and BATEMAN's specific approval.

·

A register of Change Alerts, Scope Change Notices and Approvals will be maintained.

5.2.4

LANGUAGE

All study documents will be prepared in English.  




5.3

SAFETY AND ENVIRONMENTAL

5.3.1

SAFETY OVERVIEW

BATEMAN's objective during the Study will be to develop the culture and processes to ensure the safety and health of all employees and contractors.  In striving for that objective the following criteria will apply:




·

No business objective will take priority over safety and health.

·

All incidents and injuries are preventable both on and off the job.

·

Accountability for providing a safe working environment rests with each employee.

·

All individuals have the responsibility and accountability to identify and eliminate or manage risks associated with their workplace.

·

Legal obligations will be the minimum requirements of any safety and health standards.

·

All employees (including those of contractors) will be trained and equipped to have the skills and facilities to enable an injury free workplace.

Safety is the responsibility of each person involved with the Project, and every individual will be expected to play an integral part in its promotion and in the implementation of appropriate Safety Plans.









.. .












5.3.2

SAFETY PLANS

As the greater bulk of the work in the Study is office-based, it is not intended that a study-specific Safety Plan be prepared on the basis that standard operating practices within the consultant’s premises will suffice.  However, where the Study involves site activity, the responsible consultant or contractor will prepare a Safety Plan for the work.




Each contractor will be responsible for managing their own safety program, however, BATEMAN will review Safety Plans to ensure the minimum safety standards are met.  BATEMAN will also monitor and audit Consultants and contractors on site to ensure compliance with the Safety Plans.

Before any person will be permitted to work or move on the site unsupervised, they shall have attended the site induction course.




During the study, project-specific Safety Requirements will be developed so that study bidders can take any special requirements into account when submitting budget quotations.  A draft Safety Plan for the Project implementation phase is a deliverable of the study.




5.3.3

HAZOP

No HAZOP has been allowed for during the DFS.  It is felt it is more appropriate to conduct this analysis during the Project Implementation Phase.  However an internal "Preliminary Environmental & Hazard Review" has been scheduled and allowed for in the Budget Estimate.




5.3.4

COMPLIANCE WITH ENVIRONMENTAL REQUIREMENTS

In order to ensure that all areas of the Project are in compliance with the environmental requirements of the Project, the following actions are proposed:




·

At the outset, all relevant Consultants will be issued with the procedure that outlines the specific requirements that study participants need to be alert to in the conduct of their work.

·

At certain points throughout the design process design documents will be reviewed on a formal basis to test compliance with the environmental requirements.

·

In the event of any significant issues or fatal flaws being revealed by the reviews, the parties concerned will meet with MMB and the environmental Consultants to discuss the issues and agree alternative designs or mitigation measures.

·

All field activities will be undertaken in accordance with the established guidelines and procedures in place in Mexico.




5.4

ENGINEERING

5.4.1

DESIGN CRITERIA

The Project design criteria will be developed during the course of the study.









.. .















5.4.2

STANDARDS, SPECIFICATIONS AND DATA SHEETS

Baja California Sur, being a State of Mexico, is governed by the standards that apply in Mexico. Given that funding for the Project is likely to be of European or American origin it is important that globally accepted standards are met in certain areas particularly those of the resource estimation and the environment.  It has already been stated that the environmental study must meet the requirements or standards of the World Bank for example.  In essence the most appropriate standard (i.e. typically the higher of two options) will be used.  




It is intended that documentation be of a consistent format and quality across all Consultants.  At the commencement of the study, it is intended that the Study Manager will discuss this topic with the Consultant Co-ordinators after which a policy will be agreed for the Study.




5.4.3

DESIGN REVIEW, VERIFICATION AND VALIDATION

The design processes used throughout the Study will be in accordance with BATEMAN's Study Quality Plan, and with Consultant's Quality Plans, which will be reviewed and approved by BATEMAN.




5.5

DRAWING OFFICE

5.5.1

DRAWING OFFICE PROCEDURES

It is intended that drawings be of a consistent format and quality across all Consultants.  At the commencement of the study, it is intended that the Study Manager will discuss this topic with the Consultant Co-ordinators after which a policy will be agreed for the Study.




5.6

PROCUREMENT AND CONTRACTING

5.6.1

PROCUREMENT AND CONTRACTING STRATEGY

The proposed procurement and contracting strategy for the Project is outlined below.  The ultimate contracting strategy adopted for the Project will unfold as the Study progresses and will be the subject of a range of factors including client input.  




·

Mining area: owner mining although the mining studies will consider the possibility of mining by contractor.

·

Project civil works, including earthworks, dynamic compaction, piling, foundations, roadworks and drainage: generally on a schedule of rates basis administered by the EPCM contractor.

·

General packaging approach: vertical packages (above foundations) bid and awarded as lump sum turnkey contracts where possible.

·

As a general rule, BATEMAN will prepare the enquiry documentation to suppliers and contractors based on technical documentation prepared by core Consultants.  The relevant Consultants will participate in the evaluation process.  This general rule will not apply to the mining area, where tenders will be sought by the geology and mining consultant.

5.6.2

STUDY PRICING APPROACH

The following general approach will be used for obtaining prices for the study:












.. .












·

All equipment that forms part of the process plant equipment list will be issued to tender for budget pricing against data sheets and technical specifications that will be prepared as part of the study.  Typically, a minimum of three prices will be sought and equipment selections made according to the normal process of technical and commercial evaluation.

·

Tenders will be called for all vertical packages (such as the Sulphuric Acid Plant, the Power Plant and the H2S Plant), which will typically be issued to three suppliers against full technical and commercial documentation.  Normal technical and commercial evaluation processes will apply.

·

A similar tender process will apply for the pricing of bulk materials.

·

Where possible, work that is intended to be packaged into construction packages will be issued to suitably qualified and experienced construction contractors for competitive pricing or estimate verification. 

Deviations from this approach will be will be subject to the approval of the DFS Study Manager.




5.6.3

BIDDERS LISTS

Where competitive bids are sought, they will be sent to a minimum of three bidders unless MMB approves a lesser number.  Bidders list for major packages are subject to client review.  Suppliers and contractors with previous experience in Mexico will be preferred.




5.6.4

COMMERCIAL CONDITIONS

Enquiries issued to suppliers and contractors during the Study will include BATEMAN's standard commercial conditions, revised as required to accommodate any special client or Mexican requirements.




5.6.5

TRANSPORT AND SHIPPING

The proposed approach to transport and shipping for the Project, which is subject to review during the Study, is as follows:




·

A clearance agent would be contracted to deal with traffic into Mexico.

·

Staging areas to consolidate loads as appropriate.

·

A transport company or companies would be contracted for the transport of purchased equipment items.

·

Supply and erect contractors would be responsible for their own transport but will operate through the Project clearing agent.

5.6.6

LONG LEAD ITEMS

As part of a procurement criticality analysis in the study, long-lead supply items (say over twelve month delivery items) will be identified in order to ensure that appropriate strategies are adopted in the execution phase to minimise their impact on ultimate construction completion.




5.6.7

PROCUREMENT PLANS

As part of the study, operating plans for procured items and construction contracts will be developed as part of the planning process for the construction phase.









.. .















5.7

CONSTRUCTION AND COMMISSIONING

There are no construction or commissioning activities in the Study stage but the Study does need to consider the construction issues in order to develop a complete project development plan.




5.7.1

CONSTRUCTION PHASE APPROACH

The approach to construction and commissioning in the Project phase currently anticipates:




·

the contracting strategy described above;

·

construction using experienced contractors, making maximum use of local labour where appropriate;

·

construction supervision by EPCM contractor;

·

commissioning by EPCM contractor with support from relevant suppliers and contractors.

5.7.2

SITE ESTABLISHMENT

The Study will need to consider the issues surrounding the establishment of facilities for the construction phase as they will form part of the Project execution plan.   The current plan is to have the site established as a mix of temporary and semi-permanent facilities.  The temporary facilities will be removed at the end of construction.




5.7.3

PERSONNEL ACCESS TO SITE




All site visits will be co-ordinated through MMB in Mexico City.  




The BATEMAN Study Manager must be informed of travel plans prior to the visit to ensure that the visits are optimally discharged.  




5.8

PLANNING

5.8.1

STUDY SCHEDULE PROGRESS CONTROL AND REPORTING

For the purposes of monitoring, reporting and controlling the progress of the study, BATEMAN will:

·

update the Study schedule on a monthly basis throughout the study;

·

provide earned value by consultant and for the total study;

·

STUDY SCHEDULE

We expect a study duration of 14 months from commencement of the DFS subject to test work duration and availability of bulk samples for metallurgical test work.  Attached in Appendix B is a draft schedule for discussion purposes.




7.1

STUDY PHASES AND REVIEWS

As previously described, study activities are divided into three main phases:




·

Phase 1 – Data Collection and Options Study Phase.  This essentially involves environmental base line studies, geological drilling (if required), geotechnical drilling, bulk sampling, metallurgical testing and flowsheet development and the option studies relating to the Port and the Sulphuric Acid production.  At the end of Phase 1, the Project development concepts would be fixed.  Phase 1 has a duration of around 6 months,

·

Phase 2 – Engineering Design Phase.  This phase is essentially a production exercise, where the Project facilities are designed and quantified prior to cost estimating.  Phase 2 has a duration of around 4 months.

·

Phase 3 – Report Preparation Phase.  This phase involves cost estimating, financial analysis and report writing, editing and publishing of the DFS.  Phase 3 has a duration of around 4 months.

A number of major reviews have been scheduled, during which MMB will have the opportunity to conduct a comprehensive review of study direction and progress.  




Major reviews have been scheduled to take place around the following dates:




·

Early October 2004. A review of Process Concepts is proposed at the end of the Process Development Phase and the building of the MetSim model.

·

Late November 2004, which is approximately mid way through Phase 1 at a time when many of the options studies will have been completed and most of the fieldwork well advanced. 

·

Early February 2005, which is timed for the end of Phase 1 at which time most of the fieldwork will have been completed (except environmental), as will metallurgical testing, and the process plant design flowsheet will have been developed along with the Project mass, energy and water balance.

·

Late May 2005, which is timed to coincide with the completion of the engineering design phase.




7.2

MAJOR MILESTONES




Major milestones include the following:




·

The delivery of the Bench Scale Testwork Report.  This report is of significance because it provides direction for the Pilot Campaign.

·

The delivery of the Pilot Plant Campaign Testwork Report.  The results of this report are of significance as they feed into the Design Criteria prior to producing the Rev B Flowsheets. 

·

The production the Rev B Flowsheets which serve as the prelude to getting the other Engineering disciplines involved.  In effect, the Rev B Flowsheets form the basis of the Process Package.














·

The completion of the Plant Layout & General Arrangement Drawings.  This allows materials take-offs to be conducted enabling the Estimating function to commence.

·

Finalising the Estimate in early July 2005.

BUDGET ESTIMATE – DEFINITIVE FEASIBILITY STUDY

BATEMAN have offered a Budget Price of US$ 6 365 220  (six million, three hundred and sixty five thousand, two hundred and twenty dollars US).  This figure is broken down in the table below. 




Note that a major assumption which affects both the Study Budget Estimate and the Study Schedule is that the process development will proceed smoothly without significant changes of direction being required. Once greater study definition has been achieved, more accurate costs, timings and allowances can be made for the work required for the delivery of a DFS.  




The basis of the cost estimate is the various proposals provided to BATEMAN by numerous Consultants.  BATEMAN costs have been built up from a list of deliverables and tasks required to deliver the Study.  The exchange rate applied is AU$1.00 = US$0.70, the rate as at 10th June 2004.

This was financed 100% by guarantees from the US Ex-Im, Czech EGAP and Israeli IFTRIC credit agencies.  The Project represents the first time that Ex-Im has agreed to finance a gas project in Turkmenistan.  It is also the first time that Ex-Im has entered into a joint financing project in Central Asia with IFTRIC and EGAP.




BATEMAN’s $100 million project for Tomskneft in Siberia for the turnkey supply of a large gas compression and treatment station, represents one of its largest financed project references to date. A significant factor contributing to the implementation of the Project was BATEMAN’s ability to successfully structure and secure a 100% financial package needed to finance the Project.  Financing was obtained by a co-finance agreement between the US Ex-Im Bank and Israel’s IFTRIC, the first of its kind, with input of other Western and Russian banks.  The Project was also the first to be financed under the Oil and Gas Framework Agreement between the Russian and the American Governments.




BATEMAN has a proven record in all types of project finance, including structured, export, trade and project finance.  Years of international experience grant BATEMAN the benefit of a global approach where all sources of finance are examined, internationally and locally.




Several successful projects, other than those above, have already been completed or are currently underway, proving the group’s abilities.




The £27 million ZISCO Project (Zimbabwe Iron and Steel Co.) in Zimbabwe, commissioned in 1996, for the construction of the world’s longest (15.6km) overland single flight troughed belt conveyor was jointly financed by the country of Zimbabwe, the South African CGIC and the British ECGD.  Ingenuity was required in order to arrange project financing, minimise project costs and to fulfil each country’s stipulations and benefit profiles.









.. .















The ALROSA Aykhal and Nurba Projects in Yakutia (Siberia) were structured with South African CGIC guarantees to a first phase value of US$27 million.  This work involves a greenfields diamond mine feasibility study, a bulk processing plant and two major upgrades of existing factories. Commissioning of the first phase will be in the year 2000.




The Kasese Cobalt Project in Uganda, commissioned early in 1999, was structured with $60 million of financing from several international banks, backed by CGIC guarantees.




The Sangan Iron Ore Project in Iran, due to begin in early 2001, has been made possible by a specially structured finance package of $140 million put together by BATEMAN with both the Canadian EDC and the South African CGIC.




BATEMAN was involved in structuring a $70 million finance package for the Ecopol Project in Poland.




Other successful financing facilitations have been provided to projects in the Ukraine, Georgia (FSU), Karg Island, Honduras and the DRC (Zaire).  These again underline the depth of experience and expertise that BATEMAN can bring to bear on international projects where tax and financial structuring can bring substantial benefits to the client.




BATEMAN has established a sound reputation in its dealings with the major first class bank, for example, ABN AMRO, Standard Bank, ABSA Bank, BOE Investment Bank, Ing-Barings Bank, Barclays Bank, Exim Bank, IDC SA, Rothschilds and Natwest Bank.  Coupled with this profile are good relations with, and experience of dealing with the Credit Agencies in obtaining the political and commercial cover required for the Projects.  Some of the agencies BATEMAN has had business dealings with are CGIC (South Africa), EDC (Canada), ECGD (UK), IFTRIC (Israel), MITI (Japan), EGAP (Czech) and EXIM (Turkey).




BATEMAN believes that a project must contain the correct level and profile of financial and taxation structuring in order to optimise client benefits.




BATEMAN has utilised South African export finance on many projects over the years since first arranging finance for the Dwangwa sugar mill in Malawi, Central Africa, in 1976.  This can be greatly advantageous for projects, which wish to take advantage of competitive South African equipment, material and labour costs.




Through its activities, BATEMAN has built close personal and professional relationships with CGIC staff at all levels up to the CEO of CGIC.  Some of the export destinations that have been involved are Angola, Australia, Argentina, Brazil, China, Colombia, Chile, Egypt, Guatemala, Honduras, Hong Kong, Iran, Israel, Mozambique, Russia, Saudi Arabia, Thailand, Turkmenistan, Uganda, USA, Zimbabwe, Zambia and Zaire.
