The BFS has demonstrated a highly robust business case for a 60ktpa operation at Epanko and has also substantially enhanced and de-risked the project’s development. Discussions are progressing with both existing and new blue-chip German industry partners for the sale of additional products. These arrangements will support the downstream processing of Epanko graphite to produce spherical graphite products for the high growth battery market, which has the potential to provide significant additional value and increase margin capture. A separate feasibility study on the production of battery grade spherical graphite and value add graphite products is currently being finalised and is expected to be released in Q3 2017.

Kibaran Managing Director Andrew Spinks commented: “This detailed updated feasibility study shows that Epanko is a world-class graphite project in every respect. The outstanding quality of the deposit underpins the project’s extremely robust economics, demonstrated by the strong alliance the project has managed to secure with a range of German industrial groups. Passing this milestone was the key catalyst to advance debt financing and allows Kibaran and its sales partners, industry groups and private equity groups that have previously expressed interest, to commence project financing discussions in detail.

The support of such partners has facilitated the increase in production to 60ktpa and underpins the commercial development of the downstream processing facility. This places Kibaran in the ideal position for the enormous growth forecast for graphite demand, on the back of the increased electrical vehicle and renewable energy battery boom. The downstream processing plant is expected to provide the Company with another source of substantial cash flow generation by supplying our products to lithium battery manufacturers.”

BANKABLE FEASIBILITY STUDY SUMMARY

SCOPE OF WORK

In order to achieve the highest standard required by our lenders and to accommodate an upgrade in production, Kibaran has undertaken a 12 month program of work recommended by SRK which encompassed almost every facet of the projects metrics, costing over US$8m and involving leading consulting teams from Australia, Africa and Europe. The quality of the BFS has been significantly enhanced through the involvement of SRK Consulting. Their diligence and rigour has resulted in a bankable level of project definition. Potential value adding opportunities have also been identified and will be incorporated as the project is progressed.

SRK Consulting, appointed as Independent Engineers for KfW, to perform KfW’s technical due diligence on the project concluded with the following:

  • The additional work SRK required to be undertaken by Kibaran to update the 2015 Feasibility Study has been completed in its entirety

  • All technical areas have been significantly advanced to conform with the requirements of international project financing standards

  • The Environmental and Social Management Planning and supporting impact assessments conform to relevant Tanzanian legislation, IFC Performance Standards and World Bank Group Environmental Health and Safety Guidelines

Achieving this positive outcome is the catalyst for securing debt financing for the Epanko project and Kibaran is now engaged with a number of lenders. Following a positive initial review, the Company has commenced an international debt financing program under the leadership of KfW, a leading German bank which has extensive experience in the successful financing of development projects around the world.

TECHNICAL

Over 8,000m of resource drilling was completed, together with a new program of geophysics and structural geology that has increased resource confidence levels, extended the scale of resource and importantly confirmed the continuity of graphite mineralisation along strike, which provides the potential to extend forecast mine life beyond the current 18 year plan.

2

==> picture [29 x 32] intentionally omitted <==

This drilling and associated testwork provided data for hydrological studies, geotechnical programs and the design and optimisation of new mining pits and a new mining schedule.

Additional metallurgical testwork was undertaken on both drill samples and on a 200 tonne bulk sample. The bulk sample was successfully processed through a commercial scale graphite plant to produce final processing parameters and provide credible production scale samples for assessment by key offtake partners.

During the study Kibaran explored the potential to generate a higher carbon grade product from <150 micron material for use as spherical graphite feedstock. Importantly, starting with high grade and large flake provides significant flexibility in process flowsheet design. Fresh material which comprises 28% of the Ore Reserve and 72% of the Mineral Resource produces a product grade of 99% carbon with no modifications to the process flowsheet. Both the Eastern and Western pits remain open at depth and any conversion of Mineral Resources to Ore Reserves will be fresh material.

GR Engineering have utilised this mining and processing data to refine designs for the mine processing flowsheet and optimise the overall mine configuration to provide the most effective and efficient operating plan for Epanko. This has included additional studies for all required infrastructure, associated access roads and minesite facilities.

SOCIAL, ENVIRONMENTAL AND SAFETY

Over US$2m of the total US$8m expenditure was directed to the environmental and social disciplines, in order to conform with IFC Environmental & Social Performance Standards and the Equator Principles and to progress the Resettlement Action Plan to near completion. This builds on the Company’s commitment to ensure global best practice in community relations and environmental management. The Kibaran team has a strong track record in community relations and environmental management with a previous project in which they were involved receiving two Presidential Awards in Tanzania for environmental excellence and with Mr Grant Pierce, our in-country Executive Director, receiving the Order of Australia Medal for his contribution to rural communities in Tanzania.

The environmental and social program was assisted by UK based Zyl Consulting and consisted of an intensive on-ground process of environmental review and social engagement involving the Company’s in-house social development and community relations team, together with experienced resettlement, social and environmental professionals such as independent valuers, surveyors, planners, architects and engineers.

In addition to the Company’s Resettlement Policy Framework and Social Engagement Plan which have been made public via the Kibaran website, a comprehensive environmental and social strategy has been developed in accordance with the Equator Principles and is supported by a suite of 14 detailed management plans to ensure impacts and risks are identified and managed in accordance with leading global standards.

KEY OUTCOMES

The BFS evaluated both a 40ktpa and 60ktpa graphite operation at Epanko, with the 60ktpa case delivering superior capital efficiency and financial outcomes under updated inputs.

Pre-production capital costs are estimated to be US$88.9m, including a US$7.1m contingency. The BFS results deliver an improved capital efficiency compared to the July 2015 study, as demonstrated by the 24% reduction in capital intensity from US$1,937/t to US$1,482/t concentrate. Capital cost estimates were re-quoted to reflect Q1 2017 market prices and monetary terms.

The BFS estimates a C1 Free-On-Board (FOB) operating cost of US$500/t and an All In Sustaining Cost (AISC) of US$572/t. The C1 FOB operating cost is significantly lower than the estimate in the July 2015 study of US$570/t (and AISC of US$622/t). The improvement is primarily due to lower power costs arising from accessing grid power after 2019 and the increased ore throughput delivering process cost efficiencies. Mining costs are based on a contractor mining scenario with the lower costs driven by the lower strip ratio compared to the July 2015 BFS (0.4 versus 1.1 waste to ore). Operating cost estimates were re-quoted to reflect Q1 2017 market prices and monetary terms.

PROJECT FINANCING

A positive outcome of the technical due diligence of the updated Epanko BFS by the Independent Engineer SRK Consulting has been the catalyst to facilitate credit approvals by debt financiers. Following a positive initial review, a debt financing program has commenced under the leadership of Germany’s KfW to determine the optimum structure, quantum and terms of the debt facilities.

In conjunction with the KfW process, the Company is also working through assessment processes with Nedbank Limited, acting through its Corporate & Investment Banking Division (‘Nedbank CIB’), one of the largest banks in South Africa and a key lender across the African continent, together with Australia’s Export Finance and Insurance Corporation (‘EFIC’). Both institutions have indicated potential support for the proposed development and following completion of the BFS, the Company and the international banking group are currently preparing a detailed, multi-party program to complete all project requirements and secure debt financing facilities.

A number of strategic equity investors, including both industry participants and private equity groups, have also expressed interest in potential investment in the project and the downstream processing value adding initiatives. The Company is progressing these discussions in parallel with the debt financing program in order to determine the preferred debt and equity funding structure.

MARKETING AGREEMENTS AND ADDITIONAL CUSTOMER SUPPORT

The executed marketing strategy for the Epanko project is focused on the supply of high quality graphite products into specific geographic markets which are seeking a diversified and consistent long term supply partnership.

As a result, the project has secured strong support from German, Japanese and South Korean markets with existing sales and binding offtake agreements for 44ktpa of planned graphite production. The Company is in discussion with its key partners and other leading German carbon groups for the sale of an additional 16ktpa of graphite products. Negotiations are well advanced and the Company expects to formalise agreements in due course.

In addition, the Company has also received positive support for its proposed value adding downstream processing initiatives, including for the purchase of both battery grade (spherical) graphite production and byproducts (fines), together with co-investment in the planned downstream processing facilities.

The BFS is based on the conservative assumption that all products are sold into the German, Japanese and Korean markets for use in traditional graphite applications, primarily as refractory products in the production of steel and iron materials.

Kibaran firmly believes that near term to medium term demand growth for graphite will be a function of Electric Vehicle (‘EV’) penetration rates (for which numerous independent forecasts are available). The interest in our battery grade graphite samples has significantly increased since the Company commenced its separate feasibility study with additional German support further aligning the Company strategy with German industry, which is expected to experience significant growth through participation in the EV supply chain.

DOWNSTREAM PROCESSING

Consistent with the demand outlook, Kibaran is nearing the completion of the feasibility study for the production of battery grade spherical graphite targeting value capture of high quality Epanko graphite in the battery anode supply chain and other value added products. The study is due to be completed in Q3 2017 and is based on a staged integration with the ramp-up of graphite production at Epanko. The initial downstream processing throughput of 10ktpa to deliver approximately 6ktpa spherical graphite with testwork supporting a 50% yield which is superior to existing feedstock.

It is planned to adopt a modular process route, enabling the Company to progressively scale the production of spherical graphite products in accordance with market demand. Preliminary results include:

  • Positive feedback from end users on product suitability from the industrial scale production of spherical graphite in testing facilities

  • Key properties, including particle size distribution, tap density and impurity levels are in-line with and meet leading battery anode manufacturer specifications

  • Design and work for micronisation and spherical shaping has been completed, with the purification process flowsheet nearing completion

  • Battery testing is continuing at leading testing facilities, with the results expected shortly

The initial results support the Company’s strategy to become a key player in the supply chain for the growing battery market, which is planned to be progressed through Kibaran’s existing binding agreement and partnership with Sojitz Corporation of Japan, supported by on-going discussions with key anode manufacturers.

Downstream processing is expected to provide a floor price for mine gate products, given the access to the value added markets through the additional processing facility .

LEADERSHIP IN GRAPHITE PROJECT DEVELOPMENT

Accomplishing the positive outcomes of the BFS and the associated marketing and downstream processing progress provides the Epanko Graphite Project with a number of key competitive benefits in terms of early mover advantage.

Kibaran is the only listed graphite Company globally that has completed a BFS with Environmental and Social Planning which conforms with IFC Performance Standards and World Bank Group Environmental Health and Safety Guidelines. This status will be a significant advantage, given the emerging new markets for graphite, including batteries, are seeking to ensure graphite supply from sources which conform with such standards.

Key Competitive Advantages

  • Rigorous Independent Engineer’s due diligence significantly de-risks the project

  • Compliance with IFC Performance Standards and World Bank Group Environmental Health and Safety Guidelines provides green and social credentials which are now becoming pre-requisites for sales and partnerships

  • Secured sales and offtake agreements with established and credible partners in both Europe and Asia

  • Executed marketing strategy with strong alignment to German industry and the battery supply chain in Japan, Korea and Taiwan

  • Access to grid power and close proximity to road and rail infrastructure

  • Favourable gangue mineralogy with high degree of metamorphism which determines the graphite crystallinity

  • High proportion of large flake graphite products with high in-situ ore grade

  • Representative commercial scale testwork completed successfully, with a 200t bulk sample processed through an operating graphite plant providing samples to support process design testwork and marketing

The Ore Reserve has been reported at a 5% cut-off grade due to a reduction in the economic cut-off grade determined by the BFS.

MINERAL RESOURCE ESTIMATE

The Ore Reserve forms part of a significantly larger JORC resource of 30.7Mt grading 9.9% TGC for 3,049kt graphite (67% classed as M&I). The extent of mineralisation in the resource envelope plus the potential for strike and depth extensions, highlights the potential to both increased production rates as market demand allows and extend the LOM.

A substantial amount of graphite mineralisation exists within the reported Mineral Resource at lower TGC grade at 5% TGC as follows, 113.3Mt at 7.2% TGC for 8.1Mt contained graphite (refer ASX release 31 March 2017, Epanko Mineral Resource Upgrade ).

MINING

Mining operations will commence in the Eastern Pit and move to the Western Pit in Year 6 through to the scheduled reserve exhaustion in Year 16. The average LOM strip ratio is expected to be 0.4:1 (waste to ore).

Mining will be undertaken via conventional drill and blast with the fleet comprising of an 80t backhoe excavator and 40t off-highway haul trucks. The BFS is based on a mining contractor scenario.

The Western Deposit consists of mining a strike length of 1,360m along the top of the ridge to a depth of 210m in the south, and the Eastern Deposit sits partially over a hill within a small valley and will be mined to a depth of 125m and the pit will have a strike extent of 350m.

PROCESSING AND METALLURGY

The process plant is designed with a throughput capacity of 720ktpa for an average TGC grade of 96% and average annual production of 60ktpa. The process plant is based on a crush and grind comminution circuit (two stage crushing circuit with single stage rod mill) followed by rougher flotation. The tailings are reground in a ball mill before they enter the scavenger flotation. The rougher and scavenger concentrates are combined and fed into the primary cleaner section, consisting out of polishing mills and cleaner flotation banks. The concentrate is than screened into two size fractions, with subsequent polishing and four stage cleaning applied with no further milling required in the cleaning circuit. Product is then dewatered, dried and screened into saleable size fractions. The flowsheet is optimised for a high yield of large flakes, however it could be easily modified to get higher carbon content by flotation if required.

Notes for table 4 & 5. 1mm=1000 micron and fixed carbon content determined by Loss on Ignition method (LOI)

During the study Kibaran explored the potential to generate a higher carbon grade product from <150 material for use as spherical graphite feedstock. Importantly starting with high grade and large flake provides significant flexibility in process flowsheet design. Key findings included:

  • Fresh material which comprises 28% of the current Ore Reserve and 72% of the Mineral Resource produces an average product carbon grade of 98.2% and 99.0% carbon grade for the Western Pit with no modifications to the process flowsheet. Both the Eastern and Western pits remain open at depth and any potential additions below the current pit floor will be fresh material.

  • Potential to introduce low capital additional attritioning stages into the flowsheet to produce a higher grade carbon content product in <150 micron material for use in technology applications

INFRASTRUCTURE

Tailings Storage facility

The waste output (tailings) from the flotation process will be pumped from the processing plant to a Tailings Storage Facility (TSF).

The TSF design allows for an 18 year life of mine, at an average production rate of 60ktpa graphite product delivering an annual average of 660ktpa of tailings to the TSF.

Power

Epanko is expected to have installed power of 2.8MW and a maximum power draw of 2.4MW. The study has assumed on site diesel generation for project construction and the first years of production. From Year 2 power is expected to be sourced from the TANESCO grid through a dedicated 33kv powerline from an upgraded Ifakara Substation to Epanko.

Water

Process water supply for the main process will be sourced from the tailings storage facility and supernatant water storage. Raw water supply will be sourced from pit dewatering and the raw water supply borefield. The borefield will comprise two bores with sufficient capacity to supply the necessary volume required for the project infrastructure requirements.

Logistics

The Epanko project site can be accessed from the existing national road network to the chosen export port of Dar es Salaam. The transport route runs from Dar es Salaam to Epanko. The road from Dar es Salam to Ifakara is bitumen, and the 120km road from Ifakara to Epanko is predominantly compacted laterite.

The BFS assumes road haulage to the port of Dar es Salaam in bulk bags, however, as production increases a combined road-rail link may be utilised. Epanko is located ~120km from the Ifakara rail siding which links to Dar es Salaam.

PROJECT IMPLEMENTATION SCHEDULE

An overall Project schedule has been updated as part of this Study. The schedule has based on specific design requirements, preliminary vendor nominated manufacturing and delivery periods and in-house experience with similar projects. Some of the more significant schedule milestones are listed below:

PRODUCT SPECIFICATION AND MARKETING

The high proportion of >150micron flake size product and high graphitic carbon product grades allows Kibaran to sell product into established markets. Kibaran has demonstrated a high quality product, relative to incumbent production sources from China, through the securing of pre-production offtake agreements with ThyssenKrupp, European Trading Group and Sojitz Corporation which covers 73% of Epanko production once name plate capacity has been reached.

Product specifications including carbon content and sizing has been developed in discussions with our binding sales and offtake partners and discussions with established graphite users and traders across both industrial and technology (battery) markets. The average carbon content of Epanko product envisaged by the BFS is >96% carbon grade across 4 size fractions to meet market demand which is currently dominated by traditional industries and is expected to maintain the majority of market share during the initial years of production.

ADDITIONAL SALES SUPPORT AND DOWNSTREAM PROCESSING ARRANGEMENTS

In support of the expanded production rate of 60ktpa Kibaran has experienced additional demand from European and Southern Asian graphite markets. Discussions are well advanced and it is expected that this interest will be developed through additional sales agreements.

The Company has also received positive market support for its proposed value adding downstream processing initiatives, including for the purchase of both battery grade (spherical) graphite production and by-products (fines), together with co-investment in the planned downstream processing facilities.

EPANKO PRICING

Kibaran engaged leading independent industrial minerals forecaster Roskill Consulting (‘Roskill’) to provide updated graphite product pricing forecasts, based on Industrial Minerals quoted prices.

Kibaran expects to produce a portion of larger flake size and higher carbon content products than is quoted by leading forecasters and therefore Kibaran has made adjustments to capture the expected prices for its higher quality Epanko product. Roskill prices are based on a CIF basis.

The assumed 2017 basket price, after adjusting for CIF deductions, is US$1,181/t in the BFS and represents an 18% reduction to June 2015 study basket price of US$1,446/t.

Kibaran has not reflected any potential pricing dynamics from high growth markets in the BFS, including spherical and expandable graphite, however it is expected that graphite demand growth will be a function of Electric Vehicle penetration rates (for which numerous independent forecasts are available). Kibaran has demonstrated that Epanko product is desirable as a feedstock for spherical graphite and has superior expansion properties, which provides excellent suitability for production of expandable graphite.

CAPITAL AND OPERATING COSTS

Pre-production capital costs are estimated to be US$88.9m, including a US$7.1m contingency. The BFS results deliver an improved capital efficiency compared to the July 2015 study, as demonstrated by the 24% reduction in capital intensity from US$1,937/t to US$1,482/t. Capital cost estimates were re-quoted to reflect 2017 market prices.

The study estimates a C1 FOB cost of US$500/t and an All In Sustaining Cost (AISC) of US$572/t. This is significantly lower than the estimate in the July 2015 study of C1 FOB cost of US$570/t (and AISC of US$622/t) primarily due to lower power costs arising from accessing grid power after 2019 and the increased ore throughput delivering process cost efficiencies. Mining costs are based on a contractor mining scenario with the lower costs driven by the lower strip ratio compared to the July 2015 study (0.4 versus 1.1 waste to ore). Operating cost estimates were re-quoted to reflect Q1 2017 market prices and monetary terms.

EPANKO OPERATING OUTCOMES

Ore Reserve and Mineral Resource Estimate

The updated Epanko Ore Reserve of 11.7Mt grading 8.32% TGC for 971Kt graphite (2015 estimate 10.9Mt grading 8.7% TGC for 938Kt contained graphite) supports the 60ktpa production rate for an 18 year LOM. An additional 64 holes for 7,644m were completed as part of the BFS update including 43 diamond holes of 5,899m and included in the Ore Reserve model. The Ore Reserve estimate was completed by Intermine Mining Consultants.

The quality of Epanko Graphite is driven by two geological aspects, firstly the dominant host gangue mineral is a calc silicate mineral with very little deleterious elements and the Epanko rocks have undergone extremely high metamorphic pressure and temperature creating a very high crystallinity.

==> picture [156 x 87] intentionally omitted <==

The degree of metamorphism determines the graphite crystallinity and it is important to recognise this provides its physical and industrial properties. A favourable mineralogy ultimately determines recovery and quality which drives strong project economics.

The commercial benefit of these combined geological aspects is an easily liberated graphite flakes from a low cost simple flotation process that is saleable high quality graphite without further processing steps.

20

==> picture [29 x 32] intentionally omitted <==

A 200t bulk sample has outperformed the block model with assays reconciling the Ore Reserve block model grades. This positive reconciliation not only fully supports the integrity of the model but demonstrates the overall robust nature and significant upside of the Epanko Mineral Resource Estimate undertaken by CSA Global. Consistent positive reconciliations from both mineralised zones have been demonstrated.

PROJECT ENHANCEMENT OPPORTUNITIES

Significant opportunities for further value enhancement including extension of mine life beyond 18 years, incorporation of high grade graphite (>10%) encountered outside current pit design and other savings on implementation due to conservative design and costings.

Project economics do not include product sales into the high growth lithium-ion battery markets through downstream processing.

SPHERICAL GRAPHITE PRODUCTION AND DOWNSTREAM STUDY

Kibaran is nearing the completion of a feasibility study for the production of uncoated spherical graphite to capture the forecast demand growth in graphite anodes for lithium-ion batteries. The study is expected to be completed in Q3 2017.

Due to the high metamorphic gradient, Epanko graphite has a highly ordered crystal structure. This is supported by testwork indicating a D002 measure of 0.3356nm which compares to perfect crystallinity of 0.3354nm. A high level of crystallinity is important for battery applications.

The study has considered a number of potential milling and purification flowsheets, including site visits to spherical graphite production plants and potential equipment vendors outside of current producing facilities.

Figure 15: Current natural graphite process chain to anode material by process and geography

==> picture [504 x 73] intentionally omitted <==

Source: ProGraphite 2017 - Industrial Minerals Conference in Berlin

The initial findings favour a grinding and shaping (which are mechanical processes) flowsheet based on Chinese technology. The favoured purification (chemical) flowsheet design is based on Korean technology which is less acid intensive and therefore more environmentally sustainable than other technologies.

Key parameters of the study include:

  • Staged integration with the ramp up of production at Epanko

  • Initial production of 10ktpa value-added product, consisting of 6ktpa spherical graphite and 4ktpa of other value-added products, mainly specially screened and blended products, together with micronized products

  • Yield to spherical graphite of ~50%

The ability of bringing the downstream processing into production has been significantly strengthened given advanced discussion with leading German Carbon groups for the purchase of both battery grade (spherical) graphite production and by-products (fines), together with co-investment in the planned downstream processing facilities.

The Company expects that the completion of the feasibility study will result in the Company accessing a number of funding opportunities to develop the downstream processing project.

PROJECT FUNDING

Completion of the Epanko BFS and successful completion of the technical due diligence by the Independent Engineer SRK Consulting were the key catalysts to facilitate a positive credit assessment of the project by debt financiers.

SRK Consulting have confirmed that in addition to satisfying the scope of work agreed in 2016, all technical components of the BFS have been appropriately addressed in terms of project finance standards and that the Environmental and Social Planning conforms with the IFC Performance Standards and World Bank Group Environmental Health and Safety Guidelines.

Achieving this positive outcome ensures that the proposed development of Epanko has established a platform which conforms with the Equator Principles, a global risk management framework adopted by the world’s leading financial institutions for the assessment of environmental and social aspects of project funding submissions.

Following the positive initial review, a debt financing program has commenced under the leadership of KfW to determine the optimum structure, quantum and terms of debt facilities to enable, subject to all necessary approvals, a final investment decision to allow the commencement of mine construction.

22

==> picture [29 x 32] intentionally omitted <==

The focus of this funding process is to secure, with the support of KfW, an Untied Loan Guarantee from the Federal Republic of Germany, which supports the development of businesses that can supply products deemed to be important to the future of German industry. This guarantee provides political and commercial risk insurance cover for applicable loan funds advanced to such qualified projects facilitating the provision of loan funding from KfW under terms and conditions more favourable than ordinarily available through other lending institutions.

As previously reported, the Company has received a Letter of Interest confirming “ in-principle eligibility for cover ” under the Untied Loan Guarantee scheme and the process to obtain Final Approval involves:

  • Submission by KfW of a request for Preliminary Approval by the German Inter-Ministerial Committee, which will incorporate, inter alia, the term sheet for the proposed loan funding, a detailed project information memorandum, environmental and social impact assessment, base case financial model, together with key marketing, technical, insurance, legal and taxation reports.

  • Following the Preliminary Approval, completion and submission of final due diligence reports and other documents as required.

In conjunction with the KfW process, the Company is also working with Nedbank CIB, one of the largest banks in South Africa and a key lender across the African continent, together with Australia’s Export Finance and Insurance Corporation (‘EFIC’). Following recent discussions with KfW, Nedbank and EFIC, the parties are considering the potential to progress the project financing program on a joint basis so that the preparation of project assessments, key agreements and the finalisation of credit commitments and supporting loan documentation can be progressed expeditiously.

A number of strategic equity investors, including both industry participants and private equity groups, have also expressed interest in potential investment in the project and the downstream processing value adding initiatives. The Company is progressing these discussions in parallel with the debt financing program in order to determine the preferred debt and equity funding structure for the proposed development.

Squared (IDS) estimation was concurrently run as a check estimate.
The composited drill sample data were statistically analysed, examining the
relationship between TGC and weathering profiles, hole types, and
structural domains. A variography study was also carried out examining the
influence of structural domains (principally the impact of the D2 faults in the
Western Zone). Within the oxide domain there was a population difference
noted, but no discernible population differences were noted in the fresh
rock domain. Variogram models present a very low relative nugget effect
(<15%) for the Western and Eastern zones, with ranges typically between
90m and 170m. Short ranges at the first sill were also modelled.
Due to the low nugget effect, a low number of samples were required for
grade interpolation, with a minimum of 4 and maximum of 12 composited
samples were used in any one block estimate for the Western and Eastern
Zones. A maximum of 5 composited samples per drill hole were used in any
one block estimate. Cell Discretisation of 5 x 5 x 5 was used. Grade
interpolation was run within the individual mineralisation domains (Epanko

hard boundary for both Western and Eastern deposits.

The Inferred classification level was applied to the volumes where geological

Mineral Resource classification was carried out by stepping through both
the West and East models, and creating 3D wireframe surfaces constraining
the resource classification levels (Western Zone) or by applying northing and
easting limits (Eastern Zone). Weathering profiles also controlled the
classification, with the oxide weathering zone generally classified at the
same or higher level to the adjacent blocks in transitional and fresh zones,
due to high confidence in the geological continuity of graphitic schist as
observed in outcrop and from trench data.
