The Life of Mine (LOM) commercial exploitation of the diamond resources in Nos. 1 and 2 Kimberlite pipes, the enlargement on Dyke Zone "A" and enlargement on Dyke Zone "B", Dyke Zone "A" and Dyke Zone "B" will be preceded by the completion of a BFS in pursuit of which internationally accredited consultants will be contracted to carry out a processing plant upgrade study (85tph to 150tph) to increase current processing capacity from 50tph, in addition to core drilling, mineral sampling, bulk sampling at depth on No 2 pipe, geotechnical evaluation and geohydrology investigations The respective programmes will be undertaken in support of formulating a robust resource-statement, geological model and mining feasibility study. The BFS is expected to be completed by the end of 2009.

Phase 1. Core Drilling Programme

Core drilling will be undertaken to firm up the resource statement as well as in support of geotechnical investigation and mineral analysis as follows;

i. Proposed decline for underground access, metres 1,200 - cost US$ 184,000

ii. Dyke zones, metres 9,520 - cost US$ 1,460,000

iii. No 1 pipe, metres 2,100 - cost US$ 322,000

iv. No 2 pipe, metres 1,200 - cost US$ 184,000

v. Total capital expenditure - US$ 2,170,000

Phase 2. Mineral Sampling and Analysis

Mineral sampling to be completed in respect of Petrographic, geochemistry, and micro diamond analysis - cost US$ 52,000

Phase 3. Bulk Sampling on Dyke Zone A and Dyke Zone B.

Bulk samples will be extracted from surface on Dyke zones A and B the target would be to recover a representative parcel of 2,000 cts from each of the two dyke zones. Two options are being considered for implementation starting March 2009 namely;

• Surface mining targeting a depth of between 3m to 6m of fresh kimberlite

[signature] 30 [signature]• Civil engineering tool (Bauer Trench Cutter) targeting a depth of between 5om to 80m

Phase 4. Bulk Sample programme on No 2 Pipe

No 2 pipe has not been mined since 2005, the pipe will be de-watered and muck and silt removed in order to facilitate the refurbishing of the existing ramp down to 325m amsl. Four 23 inch diameter holes will be drilled to 250m depth each in order to extract a representative macro diamond sample. The programme is scheduled for completion by May 2009 - cost US$ 600,000

Phase 5. Geo-hydrology Drilling Programme - No 2 pipe

In order to complete the geo-hydrology programme, four 17 inch diameter holes of 200m depth each will be drilled around the perimeter of No 2 pipe - cost US$ 700,000

Capital Costs

i. Estimated minimum capital expenditure - US$5,000,000


In order to improve the cash flow situation the current 50tph processing plant will be utilized during 2009. Ore will be extracted from Dyke zone "A", Dyke zone "B", Dyke

zone "A" enlargement and No 2 pipe using surface mining methods. A Civil Engineering tool (Bauer Trench Cutter) has been identified and mobilized to perform a trial mining test on the various ore bodies and it is hoped that an effective depletion rate equating to at least 10 cubic metres per hour will be achieved utilizing this method, Dyke zone "B" will be targeted for the initial trail mining tests.

Depletion Plan 2009

i. Dyke zone "B" - Trench Cutter teal mining or surface mining - 100,000t ore.

ii. Dyke zone "A" enlargement - 20,000t ore

iii. No 2 Pipe - 170,000t ore

iv. Total mining (ore) - 290,000t

v. Total mining waste - 1,000,000t

Processing 2009

i. Dyke zone "B" and enlargement - 120,000t at a grade of 0.55ct/t (66,000cts)


[symbols]ii. No 2 pipe - 80,000t at a grade of 0.28ct/t(22,400 cts)

iii. Total processing - 200,000t (88,400cts)

Closing stockpile 2009

i. No 2 pipe - 90,000t at a grade of 0.28ct/t

Note: Grades are subject to verification after bulk sample process

Operating costs

i. Average cost per unit processed - US$80/t

ii. Total operating cas costs - US$16,000,000


The economic viability of continuing with the open pit mine plan on No 2 pipe will be assessed after the completion of the bulk sample programmes conducted on the ore body during phase 1 and phase 2. The intention is to deplete No 2 pipe over a period of four years whilst development of the underground is ongoing. A pit optimization model and a practical pit design have been concluded and these are currently under review in order to formulate a detailed open pit design. It is envisaged that a total of 20,000,000 tonnes will be mined constituting 2,100,000 tonnes of ore and 18,900,000 tonnes of waste at a stripping ration of 8.8.

IT is envisioned that the No 2 pipe open pit will be included in the total mine schedule for the LOM underground mining play. The LOM plan is subject to completion of the BPS and subsequent securing of financing. However, it is envisioned that a twin decline access method will be developed in order to deplete No 1 pipe, Dyke zone "A", enlargement and dyke zones "A" and "B".


i. The above work programme, schedules and costs are based on estimates and are subject to completion of bulk samples and feasibility studies as outlined as well as market conditions and operational/technical conditions.





Associated Minerals (as defined in the Mining Law)



The Lessee shall sell prescribed mineral products obtained under its mining operations (a) in accordance with generally accepted international business practices; (b) at the best available international market prices at the time the contract for sale is made; and (c) on the best international terms compatible with world market conditions and conditions obtainable in the circumstances. The Lessee shall make sales commitments to Affiliates only at prices based on or equivalent to arms-length sales to non-affiliated purchasers and in accordance with such terms and conditions on which agreements would be made if the parties had not been affiliated. Failure to comply with the preceding two sentences shall result in the Minister, on the advice of the Minerals Advisory Board, determining the appropriate price.

The Lessee shall establish a sorting office in Sierra Leone and will provide appropriate training or suitable citizens.

The Valuer in making his valuation shall take into account the prevailing Diamond Trading Company (DTC) diamond purchase price for Sierra Leone diamonds and shall work with the Lessee’s representative in close harmony.

In the event the Lessee is unable to accept the valuation of the Valuer on any diamond or parcel of diamonds it will notify the Minister in writing identifying each diamond or parcel of diamond that is in dispute. The Parties shall thereupon mutually decree the appointment on an Independent Valuer of international repute who will be asked to value such diamonds, at the sole cost of the Lessee. The valuation of an Independent Valuer shall be binding on the Parties. Alternatively, and with mutual agreement of the Valuer and the Lessee, special diamonds of value in excess of Five Hundred Thousand United States Dollar (US$500,000.00) may be sent for competitive


international tender. If a tender is arranged, the Valuer may be present to witness the event.

As regards marketing, the Lessee may offer its diamonds to whomsoever it wishes in a free market but the valuation set by the Valuer shall be considered to be the reserve price for a period of three months. In the event that this prices is not reached then the reserve price may be reviewed by an Independent Valuer of international repute. The Lessee's marketing strategy may inevitably alter as market conditions change but as a general rule it will always take a long term view whilst having due consideration for is financial condition. In times of difficult market conditions the Minister will be kept fully briefed on a regular basis and his views sought.

Subject to its compliance with the provisions of this Schedule, the Lessee shall have the right freely to export and sell all production be it precious metals or diamond from the Mining Lease Area without restriction, interference or imposition of conditions by the Lessor or any Agency thereof.


[Initials][Initials][Initials]SCHEDULE 5


The following policies and procedures will be followed with respect to the hiring and training of local workers.

Sierra Leone citizens will be given priority in hiring for positions which are compatible with their experience and skill. In no case will unskilled positions be filled by non-Sierra Leone citizens. Candidates will be interviewed and selected for maintenance positions at the plant and mine.

The Lessee sees training of staff at all levels as an absolute priority and will provide funds for training of suitable individuals at all levels both in Sierra Leone and overseas. In the initial states the emphasis will be on safety and the development of underground skills in all disciplines.

The Lessee will make available an annual budget of $100,000, (a) 60% of which will be used for the training of suitable employees at all levels in Sierra Leone and overseas, and (b) 40% for training of Sierra Leone students of secondary school leaving age in various technical vocational institutes in Sierra Leone.

The investment decision of the Lessee has been influenced by the knowledge that there is a large cadre of extremely able and experienced Sierra Leoneans from mine level to management, most of whom were trained by Selection Trust and NDMC. Wherever possible, suitable candidates will be found for appropriate posts, with excellence of skills, work ethic and good character being the sole criteria for employment.

It is the declared policy of the Lessee to keep expatriate recruitment to a minimum consistent with fair play, good security and efficiency.

Any contracting arrangements entered into by the Lessee will contain the provisions, that Sierra Leone Citizens are to be employed where possible, and that these employees are to be genuinely trained and groomed for higher skilled positions. Training will be provided for suitable Sierra Leone citizens in the Lessee's Sorting Office due to be set up.

This report documents the Mine Reclamation and Closure Plan (MRCP) developed to outline the general closure and reclamation programmes for Koidu Holdings SA’s (hereafter referred to as KH) Koidu Kimberlite Mining Project (hereafter referred to as KKMP).

Mine closure is an ongoing programme designed to restore physical, chemical and biological quality of areas disturbed by the mining to a level acceptable to all concerned. It must aim at leaving the area in such a way that rehabilitation does not become a burden to the society after mining operation is over. It must also aim to create a self-sustained ecosystem. Mine closure is a continuous series of activities starting from the initiation of a mining project.

In planning for closure, there are four key objectives that must be considered;

l. protect public health and safety;

2. alleviate or eliminate environmental damage;

3. achieve a productive use of land, or a return to its original condition or an acceptable alternative; and,

4. to the extent achievable, provide for sustainability of social and economic benefits resulting from mine development and operation.

Impacts that change conditions affecting these objectives are often considered under four groupings:

1.Physical stability – buildings, structures, workings, pit slopes, underground openings etc. must be stable and not move so as to eliminate any hazard to the public health and safety or material erosion to the terrestrial or aquatic receiving environment at concentrations that are harmful. Engineered structures must not deteriorate and fail.

2. Geochemical stability – minerals, metals and ‘other’ contaminants must be stable, that is, must not leach and/or migrate into the receiving environment at concentrations that are harmful. Weathering oxidation and leaching processes must not transport contaminants, in excessive concentrations, into the environment, Surface waters and groundwater must be protected against adverse environmental impacts resulting from mining and processing activities.

3. Land use- the closed mine site should be rehabilitated to pre-mining conditions or conditions that are compatible with the surrounding lands or achieve an agreed


alternative productive land use. Generally the former requires the land to be aesthetically similar to the surroundings and capable of supporting a self-sustaining ecosystem typical of the area.

4.Sustainable development - elements of mine development that contribute to the sustainability of social and economic benefit, post mining, should be maintained and transferred to succeeding custodians.In order to minimize the various impacts, risks and liabilities, it is necessary to anticipate, as early in the process as possible, potential future liabilities and risks, and to plan for their elimination or minimization. In many areas, much of the liability or risk is associated with the uncertainty of the requirements for closure and rehabilitation from the succeeding custodian (be it a government agency, community organization or corporate entity). The mining company should determine, and provide for, the requirements of the succeeding custodians, gain their support for the closure plan and minimize the risks and liabilities that may derive from succeeding custodian rejection or objection to the closure measures at the time of mine closure. It is necessary to cover the cost of plan implementation, long term operations, monitoring and maintenance of the site post closure.

This plan includes descriptions of surface preparation, soil material placement, seeding and planting, soil amendments, and monitoring of re-vegetation success. Closure activities will be Performed to stabilize the site. Closure of the mine will include efforts required to chemically stabilize the site, as well as physically stabilize ponds created, tailing piles, and removal of above-ground structures, including processing facilities. Reclamation activities will be implemented to re-establish a beneficial post-mining land use , which will consist primarily of agricultural lands. Reclamation activities will include regarding disturbed areas to provide topographic relief that blends with the surrounding areas and will include applying soil amendments, seed bed preparation, planting and performance monitoring. Where practical, closure and reclamation activities will be performed concurrently with mining activities. Concurrent closure and reclamation will reduce reclamation costs at the end of the project as well as develop and improve reclamation techniques that can be continually improved over the life of the project to maximize re-vegetation success and productivity. Pressure on land resources and available farmland is often acute and leads to over utilization and degradation of the resource base in the area. Agricultural development is one of the main areas of investment under KH’s Community Development Action plan.

There are several other reports that allude to socio-economic development issues in the mining area that are important to the closure plan. These are not covered in detail in this report but are nevertheless referenced. It is recognized that these elements of mine development that contribute to the sustainability of social and economic benefit, post mining, should be maintained and transferred to succeeding custodians.

l.l Objectives


The mine reclamation and closure program has as a major objective the conversion of mined lands to an income-generating end use. Following cessation of mine operations, disturbed areas will be stabilized and reclaimed to a number of alternative land uses that will provide income opportunities for local communities. These alternative land uses will include the establishment of cash crops. The final land uses will be determined based on the agro-economic potential of the area and through public consultation programs. Post-mining land uses will draw from the investment in the Community Development Action Plan for agricultural intensification programs.

The MRCP is based on the following general objectives:

- Limit the area of land disturbance;

- Progressively reclaim disturbed land when no longer needed to support the project;

- Conduct project activities in ways aimed to reduce post-closure maintenance and monitoring;

- Salvage buildings, equipment or materials for which an end use after closure of the mine has been identified and to remove those that have no valuable end use;

- Consult with local stakeholders to identify reclamation options which present opportunities for improved agricultural and natural resource values;

- Restore disturbed land to conditions of similar agricultural value than before the project; and

- Develop sustainable community development and income diversification programs during operations to mitigate the potential social and economic effects of the mine closure.

As the project advances, the plan will be revisited and refined to reflect changes in mine development, operating plans, environmental conditions, and public inputs. it is the responsibility of the Environmental and Community Development Manager to oversee the effective implementation of reclamation programs, to evaluate the performance of the various reclamation initiatives, to improve reclamation procedures over time with an aim toward increased productivity, and to provide the required updates to the MRCP.

1.2 General Ecology of the KH Mining Lease area and other considerations

The KKMP Mine lease is only 4 sq. km in area and represents a relatively small area of land in the Chiefdom and District. The site has been mined before by other companies and there is a progressive resettlement project currently being implemented to resettle villages within the lease. Adequate provision has been made for agricultural land at the new settlements. The lease area has also been heavily mined by artisanal miners in the past, with adverse consequences for the general ecology. Notwithstanding these, KH will attempt to prepare the land, within practical limits to an acceptable state that will encourage resumption of farming activities. A large portion of the land has been scarred by artisanal mining and the ground lies bare. Other area are affected by current mining

4activities. There are however plant communities in various areas within the lease. Plant communities represented within the project area include fallow agricultural land/forest regrowth and inland valley swamps. The dominant plant community in the area is fallow agricultural land, which has been created by past agricultural practices. Fallow agricultural land comprises plant communities that have been cultivated, but are currently fallow as a result of local agricultural practices known as a slash-and-burn techniques, which are used to clear a patch of land. The area is then cultivated for a period of one or two years, and then left fallow for several years to allow the soil to rebuild nutrient capacity to sustain agricultural crops in the next fanning cycle. Crops that are continuously grown using slash and burn techniques include rice and cassava, and a variety of other vegetables. In the past, the typical fallow period lasted between 10 to 12 years. However, increasing land pressure from a growing population has significantly reduced the fallow periods. This has resulted in an overall decrease in soil fertility in many cultivated areas.


The Environmental and Social Impact Assessment (ESIA), earned out by Cemmats and Digby Wells and Associates in 2003 covered the following areas of work:

• Environmental Baseline study

• Environmental and Social Impacts

• Environmental Management Plan (EMP) (management and monitoring)

• Community Development Action Plan (CDAP)

• Resettlement Action Plan (RAP) and

• Public consultation and Disclosure Process

The EMP, CDAP, RAP and PCDP essentially covered many aspects of the Environmental and Social Action Plan (ESAP). The ESAP defines the mitigation, management, monitoring, and institutional measures to eliminate, offset, or reduce the environmental and social impacts to acceptable levels. It defines specific actions that KH will undertake to implement these measures and to document environmental and social performance of these measures. Other plans should also complement the ESAP. Such plans define the specific procedures, actions, and monitoring needed to accomplish certain tasks required at KKMP. These include the following:

• Waste Management Plan (WMP)

• Emergency Response and Contingency Plan (ERCP)

• Mine Reclamation and Closure Plan (MRCP)

Each of these plans should be developed based on the project plans, current site conditions, and the consultants' understanding of the local and regional environmental, social, and economic conditions. These plans will require the participation of KH managers, supervisors and employees, and the implementation of the procedural activities contained within the plans.

[signature] 5 [signature]The MRCP, which is the subject of this report is intertwined with the other plans mentioned. A well implemented CDAP goes a long way to addressing many of the issues that will augur well for the community even after mining ceases. A broad description KH's CDAP is provided in Section 3.0.


Mine reclamation and closure issues need to be addressed continuously throughout the life of the mine. KH is already addressing many of the socio-economic issues through its community Development Action Plan. Such plans are not sacrosanct and would constantly need to be revised. KH will review its CDAP to ensure that programmes undertaken will continue to benefit the community post mining. KH will also address the issue of managing economic repercussions of mine closure and manpower retrenchments and will address in greater specificity closure and reclamation methods.

3.1 Community Development Action Plan

KH recognizes that a community development program is essential in ensuring that local communities do not become dependent on the mining economy, but rather have a sustainable economy following mine closure. KH will invest into improving infrastructure, education, health care, and other economic programs to promote sustainability. The CDAP presents the actions that will be undertaken to further community development opportunities in the area. An effective public consultation program is a key component to the CDAP. The CDAP identifies program initiatives, and considers key stakeholders as members of a steering committee to prioritize and implement those initiatives. The Environmental and Community Development Manager is responsible for collecting stakeholder input through public consultation, planning, development, implementation and monitoring of the community development programs. Priorities will be set to provide the funding for the community development initiatives.

The CDAP also contains economic development and diversification initiatives. Mining inherently will take agricultural land out of beneficial use that local residents currently use for agricultural purposes. Population growth is rapid in this region so even without KH, the growing population alone results in increasing competition for and pressure on the available agricultural land in the area. The land demands for the mining project therefore exacerbate an already significant land pressure issue and therefore this issue demands rigorous mitigation efforts in order to assure that the residual project impacts are reduced to acceptable levels.

KH's CDAP consists of a management strategy, broke up into recommendation that attempt to maximize benefits and minimize adverse impacts on the local community. The plan focuses on developing alternate livelihood opportunities. The key objectives of the CDAP are:


• To provide opportunities for long-term community and economic development programmes for the target community;

• To identify appropriate mitigation measures to address socio-economic issues and impacts identified in the EIA;

• To identify appropriate mitigation measures to address induced population growth resulting from a possible influx of new comers into the area,, attracted by the mine development;

• To seek ways of building mutually beneficial linkages between the affected people and other developments; and

• To develop initiatives in the district and region.

The CDAP suggests specific development initiatives. Some of these are listed below;

• Enhanced agricultural productivity through the introduction of improved crop and livestock production technology and practices;

• Improved access to form education through the establishment of educational infrastructure and facilities;

• Improved security within the communities through alliance with the National Enforcement Agencies;

• Improved access to utilities and facilities through development in those sectors;

• Improved health status through the provision of quality, affordable and accessible health care services; safe drinking water, improved sanitation and waste disposal; HIV/AIDS and STDs sensitization and awareness raising on transmission and prevention;

• Improved adult literacy through the provision of adult literacy facilities;

• Enhanced middle-level manpower status through the provision of technical and vocational skills training opportunities;

• Youth empowerment; and

• Enhance the organizational, managerial and leadership capacities through training.

Furthermore, it is anticipated that the Mining Project will restore and sustain household incomes through a combination of improved agricultural practices and alternative sources of income such as:

• Skills training;

• Livestock and fisheries development;

• Support to small/medium size enterprises, micro-credit, and training n entrepreneurial skills;

• Adult literacy, technical, vocational skills development;


• Community infrastructure rehabilitation;

• Staff capacity training;

• Community sensitization of blasting operations; and

• Health, sanitation, education and HIV/AIDS education aimed at prevention and treatment.

Relevant economic diversification concepts will be introduced into local villages through the public consultation process and community development program.

3.2 Managing Economic Repercussions of closure of mine and manpower retrenchments

Manpower retrenchment and socio-economic repercussions of mine closure will be carefully considered in the closure plan. Due ecognizance will be given to the following issues:

• Number of local residents employed in the mine and their reverting to alternative forms of employment;

• Compensation given to the employees connected with sustenance of himself and their family members after mine closure;

• Satellite occupations connected to the mining industry-number of persons engaged therein-continuance of such business after mine closes;

• Continued engagement of employees in the rehabilitation of the mining lease area and any other remnant activities; and Expectations of the community around due to closure of mine.

KH will carry out extensive consultations with local communities, local governance structures and Government on these issues.

3.3 Closure and reclamation methods

General closure and reclamation activities relevant to the KH Project are discussed in this section.

3.3.1 Facility Salvage, Demolition and Disposal

Buildings, equipment and infrastructure will be managed for closure after the mine closes down. The closure after the mine closes down. The company clinic will be left in place and handed over to a competent local or government authority to manage. Offices and other structures that are not moveable will be left in place for community use. Stakeholder input will be used to determine the final disposition of mine facilities.

Closure of the site will include the decommissioning, demolition and disposal of the plants and ancillary facilities. The process Plant will be completely demolished and removed at the end mining operations. In the case that the plant is not demolished, responsibility for its upkeep will be passed from KH to another party. This determination


will be accomplished through stakeholder participation. Salvaging of equipment and facilities will be encouraged. Disposal of various plant components will follow the guidelines of the Waste Management Plan. Following disposal of the plant, the entire area will be ripped, graded to blend with the surrounding topography, and vegetated.

Following salvage, demolition and disposal activities, the area will be graded to create a natural final topographic relief. The only material to be included in regrading the mine facilities will be inert material such as concrete, stone, and brick used for foundations. Other materials will be taken to either to a Domestic Waste or Hazardous Waste Facility in accordance with the Waste Management Plan. Compacted surfaces will be ripped to relieve compaction and reduce surface run-off and sediment transport.

During facility closure, confirmation sampling and testing of the soils will be completed as needed to verify that areas have not been impacted by hydrocarbons or other potentially hazardous substances. In the case where hazardous substances are identified, the contaminated areas will be remediated in accordance with the Emergency Response and Contingency Plan.

3.3.2 Mined areas and other areas excavated

The mining operations, especially those due to the initial surface mining of pipes 1 and 2 will create water reservoirs. There are also areas where slimes has been deposited. Pipe 2 will eventually be mined by underground mining methods. It may not be possible to fully reclaim the land and it will not be cost effective to fill up such large craters. Considering that there will be a paucity of material to fill up the large voids, fish ponds are contemplated for these areas. This issue will be investigated in detail and discussed with the community. The slimes ponds will be partially drained. In doing so, this will expose slime areas that will require reclamation. Tailings pile slopes will not exceed a 3.0 horizontal to 1.0 vertical (3.0H to 1.0V) slope. Where feasible, tailings piles will be graded to match the surrounding topography. Once regraded, tailings will be covered with plant growth medium. The surface will also be graded to blend with the surrounding where possible.

Tailings that are mine overburden will be reclaimed primarily to agricultural use. Tailings piles will be regraded but will not be ripped due to their sandy nature. Topsoil material (150 mm) will then be placed over areas where the minimum 2.0H to 1.0V slope is achievable. For most tailings piles, soil material will be placed over tailings to establish a plant growth medium. The steep slopes of the tailings piles may present several revegetation challenges. Typically, revegetation success is poor, erosion potential is high, and stability is low on slopes greater than 3.0H to 1.0V. Equipment operation is not as easy on slopes steeper than 3.0H to 1.0V, which makes planting and maintenance activities difficult. Several specialized revegetation techniques may be required for tailings piles. These may include the use of broadcast-seeding techniques, hydromulch, bonded fiber matrix or erosion blankets, and hand-planting of trees and shrubs.

[signature] 9 [signature]A number of surface mined pits and borrow areas have been and will be created as part of mining operations. In some areas, excavation of surface mined and borrow areas has created small open pits with steep highwalls. These pits represent a potential safety and stability hazard. As part of closure, pit walls will be pulled back so that slopes are no steeper than 2.0H to 1.0V. The reclamation of dry mined and borrow areas will include the addition of soil amendments and revegetation.

3.3.3 Dam Safety

The earth dams on the lease are very low dams used mainly for water storage. Water storage and other dams built should be frequently inspected and problems remedied post mining. KH will be responsible for accomplishing dam safety inspections during operations, but must plan ahead for the period after mine closure. During the operating phase of the project, KH may contract the services of a cooperative organisation for an agreed upon wage to accomplish their dam safety audits. Through this on-the-job training process, the cooperative members will be sufficiently skilled at the end of the project life to carry out these inspections without KH assistance when mining is completed. The company will assure that long term funding is available to compensate for the inspection of dams by a qualified engineer at least every three years.

3.3.4 Roads

The project will reclaim roads and trails as necessary. There are numerous roads throughout the mine area that allow access to mine operations and to local villages. Some essential roads will be repaired. However, existing roads that will not be needed can be reclaimed. The community's views will be sought on this issue. Many of the roads may be considered useful. Roads requiring closure will be ripped to remove compaction. Once ripped, roads will be regraded to blend with the local topography, limit erosion, and promote natural drainage. Culverts will be removed where necessary and the disturbed area regraded to allow for unobstructed drainage. Water bars, or small berms, approximately 25 cm tall, will be built as needed along regraded road surfaces to reduce overland flow. The water bars will also allow flow away from the water bar toward a natural draw or channel.

3.3.5 Domestic and Hazardous Waste Facilities

The Domestic Waste Facility will include putrescible materials and non-degradable wastes generated throughout the area. These wastes may include paper, cardboard, plastic, rubber, and food refuse. The Domestic Waste Facility will include a compacted soil cover (600 mm) as part of final closure. The final closure of the Hazardous Waste Facility will also require a soil cover that will be vegetated and shaped to promote drainage of surface run-off. It is noted that the primary, secondary and tertiary containment for hazardous waste will be included in concrete containment vaults. These will be fully described in the Waste Management Plan.

[signature] 10 [signature]3.3.6 Surface grading

Long-term site stability and limiting erosion potential can be achieved through site grading. Site grading will also reduce visual impacts of past mining activities by blending the affected topography with the surrounding landscape. During grading, additional disturbance will be limited to the maximum extent practical. Sediment and erosion control measures will be implemented as part of the site grading work. In general, areas will be regraded to slope in the direction of the natural drainage. Slopes will be no steeper than 2.0H to 1.0V to reduce erosion potential and to maintain slope stablility. Slopes will also be regraded to prevent ponding of water. Prevention of ponded water will be important to limiting potential mosquito breeding areas.

3.3.7 Sediment and erosion control

Limiting sediment contributions to downstream receiving waters, and establishment of site-wide erosion and sedimentation rates that are consistent with development of vegetation cover can be achieved by sediment and erosion control. At the KH Project, both short-term and long-term sediment control techniques will be employed. Short term sediment control will include implementation of a number of control techniques such as surface roughening, mulching, and installation of silt fences and rock filter barriers. The implementation of these practices will reduce erosion and sedimentation rates during vegetation establishment. These sediment control structures will require regular inspection and maintenance until vegetation becomes adequately established. Vertiver grass (Vetiveria zizanioides) could be used for this purpose. It is an introduced species that does not spread on its own. When used as an erosion control, vertiver grass has to be planted in very thick rows. Areas between the rows are then seeded. The vertiver grass acts to reduce overland flow and facilitate establishment of seeded vegetation. On-site specialists will evaluate the feasibility of using vertiver grass as a short-term erosion control method.

Long-term sediment control plans will establish drainage and flood control techniques that will be employed to prevent croplands from becoming inundated with water during the wet season. Areas will be regraded to blend with existing topography, promote natural drainage, and reduce overland flow velocities. diversion channels will be constructed to divert water around areas susceptible to erosion. Storm water controls that may be implemented for roads include water bars, slope reduction, and armoring areas susceptible to erosion.

3.3.8 Soil salvage and redistribution

Topsoil from areas such as borrow pits, spoil areas, and dam sites will be removed and stockpiled for later use in reclamation efforts. KH will develop a plan for topsoil recovery if the post mining plan will result in exposed tailings material. Several general guidelines will be followed for stockpiling soils. The height of stockpiles will be limited to the


[initials [initials]extent possible to reduce compaction and to maintain the integrity of soils. Soil material will be placed in vertical lifts to limit handling and degradation of soil structure. Soil handling should be limited to the extent practical when it is either too wet or too dry. Handling wet soils often results in the creation of mud that can harden, and create a dense, brick-like layer with low permeability. Handling extremely dry soils can result in degradation of soil structure and loss of organic matter by breaking up soil aggregates. Stockpiled soils will be redistributed as part of reclamation activities. For areas that lack suitable plant growth materials, additional stockpiled soil will be used to create an adequate plant growth. Where possible and appropriate, stockpiled soil materials will be replaced to approximate topsoil depths. Soil material will not be screened to remove stones or rocks prior to placement. The use of heterogeneous materials will help to reduce erosion potential and also provide microsites to promote vegetation establishment.

3.3.9 Domestic and hazardous waste facilities

A soil cover will be used in the closure of the Domestic Waste and Hazardous Water Facilities. The cover helps limit water infiltration into these facilities. The Domestic and Hazardous Waste Facilities will include hydrologic control structures that mitigate the potential for erosion due to stormwater run-on and run-off.

3.3.10 Seed mixtures

The goal of the reclamation program is to reestablish disturbed lands to a productive, income generating post mining land use. As such, seed mixes will comprise domestic food items and cash crops based on stakeholder preferences. The use of native species in revegetation projects is generally preferred. Non-native species may also out-compete native species and thus inhibit the reestablishment of native plant communities.

3.3.11 Plant propagation and seedbed preparation

A seed collection and cuttings program will be implemented to generate plant material for reclamation. Seed collections and vegetative cuttings should focus on obtaining samples from “mother plants” from viable populations to help maintain genetic heterogeneity. Non-destructive propagation methods, such as seed collection and cuttings, will also be used to collect plant material. For areas that will be disturbed, removal and transplanting of entire plants is a viable option. If plants are removed, the disturbance to natural communities and large-scale removal of entire plants should be avoided until absolutely necessary.

A greenhouse or lathe house should be established for plant propagation. An on-site nursery will be established. The nursery will be used to raise plants that will later be used for reclamation activities. The Environmental and Community Development Manager will oversee the nursery and greenhouse/lathe house operations.


Seedbed preparation will be undertaken utilizing a number of techniques to physically prepare the soil for planting by removing compaction, breaking-up large soil aggregates, and developing a firm, but not compacted, seedbed. Seedbed preparation increases availability of water to plants, improves root penetration, removes competing vegetation, and promotes contact between planted seeds and the surrounding soil. Depending on the nature of the soil material, seeding and planting methods, and climate, a number or techniques can be used for seedbed preparation. Seedbed preparation techniques can be divided into primary and secondary tillage techniques. Heavily compacted areas will be ripped prior to application of plant growth material. Potentially compacted areas include roads, trails, equipment storage areas, and other areas of equipment operation. Areas where vehicles with rubber tires have been operated can become severely compacted, and may require ripping to great depths than other compacted areas. Common secondary tillage methods include harrowing, packing, and rolling.

3.3.12 Seeding methods

There are two basic seeding techniques for reclaiming sites; drill-seeding and broadcast-seeding. Drill-seeding will be primarily used at the KH Project where the goal is to reclaim sites to agricultural lands. The advantage of using drill-seeding is that seeds are placed directly in contact with the soil. This placement results in good soil/seed contact and also improves germination and seeding survival rates.

3.3.13 Tree and shrub planting

In planting trees, a 30 to 45 centimeter (cm)-wide area will be initially excavated to a depth necessary to properly position seedlings. Seedlings will be placed into the hole in as near a vertical position as possible. Depending on the soil quality, stockpiled topsoil will be placed into the hole. A small collection basin will then be formed around the seedling stem to catch water. Once the seedling has been transplanted, mulch will be applied to the area. A shingle or slat may then be placed adjacent to the seedling in a position that will decrease incident solar radiation and, as a result, decrease the potential for water loss via evaporation and transpiration. The installation of tubes or cages may be considered to protect the seedlings until they have become well established.

3.3.14 Application of fertilizers

Mineral fertilizers leach readily from soils and can inhibit the establishment of native plants and germination of leguminous species. Consequently, organic fertilizers will be used where possible in the place of mineral fertilizers. A number of organic fertilizers are available for soil amendment Compost and manure can be used as organic fertilizer

13amendments. A composting program will be implemented as part of the Waste Management Plan. Compost is an excellent organic fertilizer that will be used to amend soils with poor nutrient quality. Cow or horse manure may be a good option for organic soil amendments in the future as animal husbandry programs are developed, but these animals are not common in the area at the current time. Numerous commercially available organic fertilizer products are also now available and represent viable alternatives to use mineral fertilizers. KH will evaluate the results of the soil tests to determine the most suitable fertilizer treatments. Care will be taken so that areas are not over-fertilized because high rates of fertilizer application are expensive and encourage establishment of weedy species.

The Community Development Plan includes an alignment with national institutions to develop the abilities in to test for the agronomic capability of soils and identify appropriate fertilizers for soil amendment.

3.3.15 Irrigation

Development of permanent stands of vegetation requires the establishment of plants capable of surviving without supplemental irrigation. Therefore, species adapted to the environmental and climatic conditions of the KH site area will be selected for revegetation or for use as cash crops. However, some irrigation may be required to facilitate vegetation establishment or plant selection may be a function of land proximity to a permanent water source (i.e. rice). Supplemental irrigation activities will specifically focus on providing water to sensitive areas or areas that are difficult to revegetate during the dry season.

3.3.16 Revegetation monitoring

Monitoring will included field reconnaissance during the first growing season to evaluate seedling emergence. The establishment of weeds will also be monitored twice per annum, at the end of the wet and dry seasons, for a two-year period following completions of reclamation activities.

Post reclamation monitoring will begin once site grading and revegetation is completed. Monitoring data will be reviewed to determine if reclamation objectives have been achieved. Base on the results of this review, the various programs will be continued or modified, as required. The two year period should be adequate for documenting compliance with reclamation objectives;



The progress of the closure/reclamation effort will be monitored through a programme of closure and post-closure monitoring. The elements of the closure and post-closure monitoring programs will include the following:

• Confirm the long-term stability of reclaimed surfaces, highwalls, and embankments;

• Evaluate the success of revegetated areas using ground cover, species diversity, and productivity (in reclaimed areas) as measurement tools;

• Assess the adequacy and performance of drainage structures and sediment control systems; and

• Demonstrate that water quality objectives are met.

Closure and post-closure monitoring and control programs will be conducted twice per year (dry and wet seasons) for a period of two years after closure has been completed. In the event that deficiencies in vegetation establishment are identified, appropriate mitigation measures will be taken to correct these deficiencies. Monitoring will include field reconnaissance during the first growing season to evaluated revegetation success. Monitoring will also be used to identify areas that may require supplemental irrigation or nutrients.


5.1 Reclamation schedule

In general, reclamation will be carried out in tandem with the mining operation. As areas are no longer required to support the mine operations, they will be reclaimed. Concurrent reclamation will continue throughout the life of the project, as areas are no longer needed. Once mining operations are completed in an area, final closure and reclamation activities will begin. Upon completion of final closure and reclamation, areas will also be monitored for a two-year period to evaluated program performance.

5.2 Reclamation costs

Costs associated with closure and reclamation are summarized in Table 1. The total costs of reclamation for the proposed mine plan is approximately $US 736.368 (Seven Hundred and Thirty Six Thousand Three Hundred and Sixty Eight United States Dollars). Line items are listed within the table. The following assumptions are included in the cost estimate:

• The thickness of cover material is 150 mm for the reclamation of tailings piles.

• The thickness of cover material for the domestic and hazardous waste facilities is 600 mm.

• Costs associated with plant and equipment salvaging is included in the cost estimate.

• A contingency of 10 percent is included to account for miscellaneous items.


It should be noted that since Mine Reclamation and Closure is a progressive process throughout the life of the mine, many of the environmental, reclamation and social costs would be already integrated into the operating cost of the mine, especially for the Environmental and Community Development Department. It is also assumed that provision will be made for final redundancy payments.


The MRCP will be updated from time to time to reflect the current status of the reclamation programs and to better detail the plans and actions that are anticipated. This budget for the MRCP will be modified from time to time by the Environmental and Community Affairs Department.


The public consultation process will provide local communities with an opportunity to become involved in the various stages of reclamation planning. Local communities will be consulted to determine post-mining land uses and will provide input on placement of buildings, preferred crop species, and training required to manage reclaimed areas over both the short and long-term. Transparency of the environmental and social aspects of the KH Project is important in maintaining public confidence. The environmental management and social programs should properly monitor and document activities and condition to determine how these activities are affecting employees, local communities and the receiving environment. KH will proactively solicit input from local communities and other interested stakeholders through the effective implementation of its public consultation program. The Chief Executive Officer, in coordination with the Environmental and Community Development Manager is responsible for assessing the effectiveness of the overall environmental management a social programs.

The Public Consultation and Disclosure Plan (PCDP) is an important tool for disseminating information and demonstrating transparency to project stakeholders. The Plan defines how KH will collect and disseminate information with people who are interested and/or affected by the project. The PCDP establishes the basis for how KH will conduct its business with the community, and if implemented as presented, will assure transparency in project activities as they may affect the health, safety, environmental and social conditions. In addition, KH will prepare an annual report summarizing the results of its social and environmental programs over the past year, and will present their tentative plans in these areas for the coming year. The report will disclose significant environmental, and social incidents that occurred during the reporting period and will reconcile the performance of monitoring programs, compliance issues, and anything that may be considered important to understanding the activities and performance of these programs. This report will be distributed to government agencies, project leaders, and interested stakeholders, and may be posted on an KH-hosted web site. The general information contained in the annual report will also be articulated to the public through

16its annual public consultation meeting and its more frequent local village consultation program.
