Mineral Commodities Limited (“MRC” or “the Company”) is pleased to release the outcomes of the Definitive Feasibility Study (“DFS”) on a concentrate only production scenario at the Munglinup Graphite Project (“Munglinup”) in the south of Western Australia. The DFS confirms the Company’s view that Munglinup will become a crucial asset in its overall ambition to supply natural graphite into the key high-demand battery anode markets.

Executive Chairman Mark Caruso said, “This is an important milestone in the anticipated development of the Munglinup Graphite Project which continues to deliver robust project economics as a standalone graphite concentrate producer. The DFS further enhances the Company’s ambitions to build a global, vertically integrated carbon business based on two global strategic operating production centres in Tier 1 jurisdictions, Australia and Norway, producing sustainable natural graphite concentrate as a crucial raw material for the production of precursor and active anode materials.”

Having completed the DFS, MRC has received board approval and intends to increase its ownership in Munglinup from 51% to 90% by:

  • paying AU$800,000 to GT; and

  • issuing GT with 30 million fully paid ordinary shares in MRC.

==> picture [93 x 25] intentionally omitted <==

MRCG and GT will then consider and formulate the development strategy and program for Munglinup.

Next Steps

The Company intends to implement a vertically integrated development strategy that will provide a broader range of higher value products, which diversifies the risks associated with supplying the traditional natural flake graphite market.

The Company will continue ongoing test work and comprehensive market analysis as part of a determined integrated downstream value-adding strategy focused on the production of precursor and active anode materials for consumption in the growing lithium-ion battery sector. The Company will continue technical and economic study work, considering the production of purified, micronised, spheronised and coated Munglinup Concentrate to identify the optimal economic outcome from the deposit.

Cautionary Statements

The DFS discussed herein has been undertaken to determine the feasibility to mine and process graphite ore from a production plant constructed at Munglinup. The DFS is predicated on a Pre-Feasibility Study (“PFS”) (see ASX announcement dated 30 May 2018) completed in May 2018 and is based on the same project sizing as developed during the PFS. The DFS is a continued technical and economic study of the PFS considering the development of the Munglinup Graphite Deposit. It is based on a revised Ore Reserves estimate of 4.24 million tonnes at an average grade of 12.8% TGC and builds on the mine design and engineering assessment described in the PFS. The operating parameters of the DFS differ materially from the plan and assessments described in the PFS and are based on feasibility-level technical and economic assessments. The DFS evaluation work and appropriate studies have provided feasibility-level estimates of cost and rates of return to provide an assurance of an economic development based on the DFS.

The production targets underpinning financial forecasts included in the DFS includes 61% Indicated Resources and 39% Inferred Resources over the 14-year mine life. No exploration target material has been included in the economic valuation or production target of Munglinup. There is a lower level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of additional Indicated Mineral Resources or that the Inferred Mineral Resources will add to the economics of Munglinup. However, in preparation of the production target and associated NPV, each of the modifying factors was considered and has therefore passed the “economics test”.

The DFS is based on the material assumptions outlined elsewhere in this announcement. These include assumptions about the availability of funding.

==> picture [93 x 25] intentionally omitted <==

While MRC considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the DFS will be achieved. To achieve the range of outcomes indicated in the DFS, additional funding will likely be required. Investors should note that there is no certainty that MRC will be able to raise the amount of funding required. It is also possible that such funding may only be available on terms that may be dilutive to or otherwise affect the value of MRC’s existing shares. It is also possible that MRC could pursue other ‘value realisation’ strategies such as a sale, partial sale or joint venture of Munglinup. If it does, this could materially reduce MRC’s proportionate ownership of Munglinup.

Supporting Information

This announcement is intended to be a summary of key DFS findings and is to be read together with the supporting detailed presentation titled “Munglinup Graphite Project DFS Summary Outcomes”, which discloses details of the material assumptions and underlying methodologies for deriving the above forecast financial information and production targets, including material price assumptions and operating cost assumptions.

FINANCIAL ANALYSIS

  • A financial model was built for the purpose of analysing the cash flows that would be generated by the Project. The model was used to evaluate the cash flow effects of the mining schedule and process plant.

  • The Net Present Value (“NPV”) and Internal Rate of Return (“IRR”) estimates are base case only and reflect robust EBITDA performance, debt funding of initial pre-production capital costs with payback within three years and US$102 million in forecasted corporate tax payments to the Australian government.

• Cash flows were modelled on a ‘real’ basis with no cost escalation, no sales price escalation, and no inflation. In addition, a discount rate of 7% was applied for the calculation of the Project NPV. The discount rate applied reflects the weighted average cost of capital expected from debt funding the Project.

BACKGROUND & INTENT

MRC’s wholly owned subsidiary MRC Graphite Pty Ltd (“MRCG”) entered into a Joint Venture Agreement on 17 November 2017 with Gold Terrace Pty Ltd (“Gold Terrace”), to Farm-In to the Munglinup Graphite Project. The Stage 1 Agreement gave MRC an initial 51% interest in the Project. In addition, there were provisions that allowed for the acquisition of a further interest in the Joint Venture.

Stage 1 Joint Venture Farm-In to 51%:

  • AU$3.2M cash payment representing acquisition cost to date incurred by Gold Terrace; and

  • MRC issuing 10M ordinary shares.

  • Stage 2 Joint Venture Farm-In Agreement to acquire a further 39% Interest (from 51% to 90%):

  • Completing a DFS by 17 November 2019*; and

  • AU$0.8M cash payment and MRC issuing 30M ordinary shares to the Vendor.

  • Stage 3 Joint Venture Farm-In Agreement to acquire a further 10% (from 90% to 100%).

Vendor can elect that MRC acquires remaining 10% interest for full MRC ownership by:

  • MRC issuing 10M ordinary shares; or

  • MRC granting the Vendor a 1% gross royalty on all minerals produced; or

  • Otherwise standard vendor contribution or watering down provisions to apply.

  • Due to delays, MRC requested and was granted from Gold Terrace an extension for the completion of the original DFS. The extension was granted until 31 December 2019.

MUNGLINUP DEFINITIVE FEASIBILITY STUDY - OVERVIEW

The Munglinup Graphite Project (“the Project”) lies along the border of the shires of Esperance and Ravensthorpe on Western Australia's Fitzgerald Coast approximately 640km southeast by road from Perth. The Project is 4km north of the township of Munglinup on the South Coast Highway, 107km west of Esperance and 81km east of Ravensthorpe.

The Port of Esperance handles bulk grain and mineral exports and currently supports the export of nickel concentrates and iron ore from mining operations in Western Australia. Esperance has a regional airport with 3 flights per day to and from Perth. The flight time is approximately one and a half hours. The Project is 610km by road from the Port of Fremantle, where it would export its graphite concentrate product.

The Pre-Feasibility Study (“PFS”) was completed in May 2018 and was predicated on the Project to mine and process 400ktpa of graphite ore grading 15.9% TGC over 9 years, producing a nominal 54ktpa of flake graphite concentrate resulting in an ore reserve of 3.4Mt at 15.9% TGC. The financial metrics from the PFS demonstrated robust project economics.

Following completion of the PFS, MRC made the decision to proceed directly to a Definitive Feasibility Study (“DFS”) based on the same project sizing as developed during the PFS.

  • Sensitivities of the NPV to changes in key assumptions were analysed. These were run on the following key model assumptions: flake graphite pricing, flake graphite recovery, exchange rate, discount rate, operating costs, capital costs and construction schedule (capex timing).

  • In each case, the effect of the sensitivities were considered based on historical observation of mining projects.

  • The tornado diagram above shows the variance to the base case post-tax NPV for the Project (US$111M). The most sensitive metrics are flake graphite pricing, opex and flake graphite recovery.

  • The upside case for the flake graphite pricing forecast (120% base pricing forecast from Roskill) demonstrates a post-tax NPV at US$174M. The downside case (80% base pricing forecast from Roskill) demonstrates a post-tax NPV of US$48M.

GEOLOGY & RESOURCE

  • MRC has undertaken two additional drilling programs and re-estimated the Mineral Resource since acquiring the Project. The latest Mineral Resource has been prepared in accordance with the 2012 JORC Code and is estimated at 7.99 million tonnes at 12.2% TGC using a 5% cut-off.

  • The graphite deposits are located in the northern foreland of the AlbanyFraser Orogen and are hosted by paragneisses of the Munglinup Gneiss. Structurally the prospect is located adjacent to the intersection between the northeast trending Fraser Range Fault and the northwest trending Merredin Fault.

The Munglinup graphite deposits occur as discrete layers in a zone of graphitic schists within a sequence of hornblende and hornblende-garnet gneisses. The rocks have been broadly folded about a WNW/ESE axis, with superimposed minor anticlinal and synclinal flexures. Complex small-scale folding and faulting is common in the relatively incompetent graphitic rocks and the enclosing competent hornblendic gneisses appear to be less deformed.

Targeted graphitic mineralisation occurs within saprolite consisting of clays, quartz, graphite (up to 42% flake) and goethite. Weathering extends down to at least 60m.

MINING & ORE RESERVE

  • The graphite distribution at Munglinup is well constrained and outcrops at surface. The mineralised zones lie within the weathered horizon, generally dipping to the east at around 50°. Material hardness measurements show that the deposit is free-dig with possible blasting required at the base of the deepest pits.

  • The general mine layout has been developed so that dumps and infrastructure do not encroach on areas of likely continuing mineralisation that have yet to be drilled. Exclusion areas have also been established around significant environmental and heritage areas.

  • Inferred material that is within the designed pits was included in the mine schedule using the same variable cut-off grade as the Ore Reserve. This material is generally included in designed cutbacks and predominantly scheduled later in mine life. This material will be upgraded by further drilling as part of the continuing resource development program.

  • The optimised shells selected comprised 6 open pit areas, mined over 2 stages, which initially target the higher value areas earlier in the mining plan. The stage 1 pits were optimised on the Measured and Indicated material while stage 2 optimisations include Inferred material.

  • Ore Reserve uses a variable cash flow cut-off grade

MINING & ORE RESERVE

Continued.

  • The mining method adopted is based on open pit mining and was evaluated assuming a traditional truck and hydraulic excavator operation.

  • The operational philosophy is to only operate the mine during day shift, on a 5/2 roster. Run of Mine (“ROM”) operations will continue 24/7 and be owner operated, managed by the process plant. This arrangement will reduce noise/light issues and be more attractive to potential employees. This will also enable employees to reside in Esperance and operate on a daily busin/bus-out plan.

  • Annual material movement is planned to be limited to 3.5Mt per annum for the first 3 years of operation then reducing to a maximum of 3Mt per annum.

METALLURGY

  • Significant historical metallurgical testwork exists with more than 20 metallurgical studies undertaken on the Munglinup Graphite mineralisation. These studies focused on maximising the recovery of coarse flake by minimising grinding and using multi-stage leaching to upgrade the concentrate grade.

  • Samples and head assay - The DFS Master Composite was formed from 86 intervals obtained from Halberts Main and Halberts South. The resulting composite contained 18% ironstone ore type and approximately 10% of near surface material.

  • Variability testwork program - results showed that the high-grade final concentrates can be consistently produced with TGC grades ranging from 95.0% to 98.3% after multiple stages of cleaner flotation.

  • The DFS Master Composite was prepared and underwent large batch flotation tests in order to produce concentrate for vendor and marketing purposes. The flotation scheme was based on optimisation test work and utilised larger laboratory equipment.

  • A 480kg bulk run produced a concentrate with a distribution close to that achieved in the smaller bench scale tests. The coarse flake fraction contained 48.6% of the mass with a TGC grade averaging 95.8%. The fines accounted for 51.4% of the mass with a TGC grade averaging 96%.

PROCESS PLANT

  • The Process Plant is designed to initially treat 400ktpa of ore, increasing to 500ktpa in 2027.

  • ROM ROM ore will be primary crushed and stockpiled.

• Crushed ore is reclaimed from the stockpile and fed to a scrubber. Scrubber

  • Scrubber discharge is screened, with the oversize sent to a closed circuit, variable speed ball mill.

  • Milling Screen undersize is conditioned and pumped to rougher flotation. • The flotation circuit consists of rougher flotation and multiple stages of cleaner flotation.

  • Flotation The rougher concentrate is reground in a polishing mill. • A coarse concentrate product will be screened out in the later stages of the cleaner flotation.

  • Screening

  • The concentrate from each cleaner stage (aside from the last stage) are reground in stirred media

  • Polishing mills prior to the subsequent cleaner flotation stage. • The final concentrate is dewatered and dried.

  • Drying • The dried concentrate is screened into multiple size fractions and bagged.

  • Bagging

INFRASTRUCTURE & LOGISTICS

  • Power The power requirements for the main process plant have been calculated at a total installed load of 5.3MW including all duty and standby equipment with an estimated average demand of the project being 2.5MW with a peak of 2.8MW.

Power is proposed to be supplied by a 4.0MW power station supplying power to the plant at 415V. The location of the power station and the plant MCCs have been optimised to eliminate the need for high voltage transmission and transformers. The power station will be fuelled by trucked LNG based on an onsite storage and vaporisation facility with a storage capacity design allowance of a nominal 10-11 days.

Water - A bore field with several production bores has been drilled and pump tested to ensure that the bore field will support the operation.

Buildings - Plant, administration, and infrastructure areas will be modular/prefabricated or containerised. An onsite laboratory will be constructed to support the operation. Accommodation for personnel is planned to be available in nearby townships.

Logistics - Product will be transported via road train travelling 610km for delivery to the Port of Fremantle. Product will be loaded into bulka-bags with a nominal weight of one tonne prior to transport via tautliner trailers. Approximate product weight per trip is 60-65 metric tonnes. It is estimated that approximately 3 triple road-train combinations will transport product to Port of Fremantle each day on a 5 day per week basis.

JORC Code, 2012 Edition – Table 1, Munglinup Graphite Deposit

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria Commentary
Sampling The current resource database consists of 161 air core holes, 26 RC holes and
techniques 46 diamond holes representing 8,332m of drilling and 3,569 analysed drill
samples.
Air core (undertaken by Graphite Australia) ore zone intervals were sampled
every meter using a scoop spear and the material bagged and numbered.
Waste was not sampled except for a small buffer either side of the
mineralisation.
Diamond drilling (undertaken by Graphite Australia) ore zone intervals were
sampled every meter except for ore boundaries where a longer or shorter
interval was taken. Waste was not sampled except for a small buffer either side
of the mineralisation.
Drilling Diamond drilling was done using HQ triple tube.
techniques The mineralisation occurs from surface and drilling was done to a maximum of
91m depth.
Drill sample No continuous data was recorded on core or chip recovery. Only poor sample
recovery quality and recovery was recorded for air core.
Due to the style of the deposit it is considered that any material loss is not
significant to the estimation of mineralisation. However, statistical analysis of
core recovery is still to be completed.
Logging Holes were initially logged by on-site geologists. Diamond core was relogged
and resampled in 2016.
The data and results obtained from the 2012-2013 (Graphite Australia) drilling
campaign were compared with the new logging and lab results from 2016
(AEMCO) as well as the historical logging and grades from the 1986 diamond
holes by Sons of Gwalia. The two datasets were correlated to an acceptable
level.
A comprehensive logging system was developed and included alteration (type,
style and intensity), grain size, rock type / lithology, colour, minerals, textures,
fabric, parent rock (where fresh), sedimentary setting and, graphite class and
grade.
Geotechnical aspects in the form of RQD parameters were also recorded for
the diamond core as well as specific structures and details in this regard, e.g.
alpha angles.
Sub-sampling Air core was sampled using a scoop spear.
techniques and Diamond core was cut by a diamond impregnated blade core saw and half core
sample
preparation
sampled. Re-sampling of the remaining core in 2016 for data validation
purposes (422 core samples including 26 duplicates and 19 repeat samples)
used quarter core.
Duplicates (quarter core) were taken every 20 meters during the Graphite
Australia drilling program.
Criteria Commentary
Quality of assay Standards were inserted every 20 meters. No blanks were used in addition to
data and normal laboratory QA/QC protocols.
laboratory tests Sample analysis was undertaken by Nagrom in Perth for the Graphite Australia
samples.
The graphite content is reported as Total Graphitic Carbon (TGC). Prepared
samples are dissolved in HCl over heat until all carbonate material is removed.
The residue is then heated to drive off organic content. The final residue is
combusted in oxygen with a Carbon-Sulphur Analyser and analysed for TGC.
Sample analysis was undertaken by Analabs in Perth for the Gwalia Minerals NL
samples. Two methods were used:
Fixed carbon (>40%C) – C graphite is determined as an expression of fixed
carbon, which is calculated by subtracting the sum of the percentages of
moisture in the sample, volatile matter and ash from 100 (BS1016
methodology).
Fixed carbon (<40%C) - the sample is washed with organic solvents, filtered
and washed with NaOH solution. The sample is then attacked with hot 1:1 HCL
to remove carbonates, washed and dried at 105°C, the residue is analysed for
carbon by converting the carbon to CO2 in a Leco furnace and measuring by
infra-red.
Eleven check samples (pulps) from Analabs were sent to Classic Laboratories
for cross checks. Classic Laboratories washed the samples with dilute HCL to
remove carbonates, ash at 450°C to remove organic carbon and assay by Leco
furnace for the remaining fixed carbon / C graphite. Check assays (>10% fixed
carbon) were all within ±10% of the original Analabs assay. Analabs assays
within the range 5% - 10% fixed carbon was approximately 15% lower than
Classic’s check assays.
Verification of Four twin holes were drilled by Graphite Australia near (8-14m) the historical
sampling and diamond holes by Sons of Gwalia.
assaying The database containing drilling data and results was provided by Graphite
Australia. A review of the data was done by the project field geologist Mr Luke
Forti and the accuracy of the data was discussed with him during a number of
meetings with AEMCO during 2015. Confirmation on the integrity and accuracy
of the data was provided.
A visual review of the diamond core was then done by AEMCO in 2016 to
confirm the historical logging by Graphite Australia. Any outstanding
information was recovered from the diamond core and updated geological
logs were created.
Diamond core was relogged and resampled in 2016. 422 core samples were re-
analysed by Nagrom during April 2016, including 26 duplicate and 19 repeat
samples to confirm grade results. GGC01, GGC08 & GGC09 standards were
used.
The data and results obtained from the 2012-2013 (Graphite Australia) drilling
campaign were compared with the new logging and lab results from 2016
(AEMCO) as well as the historical logging and grades from the 1986 diamond
holes by Sons of Gwalia. Any discrepancies or errors were either corrected or
the results rejected.
Location of data All exploration drillhole collars were re-surveyed to 0.05m accuracy by
points Esperance Surveys in July 2016. In total 90% (179 holes) were re-surveyed to
confirm location integrity. Average variation from the original field survey in all
directions was less than 2m.
Criteria Commentary
Holes drilled since 2016 have had their collars picked up by GPS. These hole
collars will be surveyed in the future.
Air core holes were down hole surveyed at the end of the hole only. Diamond
drill holes were surveyed at 30m depth and the end of hole.
Local grids were established at each of the prospects then later converted to
GDA94. Hole collars were originally surveyed by GPS only.

structure
Sample security Graphite Australia followed a disciplined QA/QC process as is evident from
their database and chain of command documents. AEMCO followed the same
procedure and personally took all resampled material to Nagrom and
recovered the processed sample material for storage with the remaining core
and air core samples at a secured location in Welshpool, WA.
Audits or reviews An audit was conducted by Coffey Mining Pty Ltd in 2011 prior to the
additional drilling undertaken by Graphite Australia. The review stated:
“Resources and reserves are assessed to be non-JORC compliant, given the age
and the lack of available core. However, given the level of documentation
provided, and the extent to which an auditable trail exists in relation to the
modelled resources and reserves, the metrics presented are credible and serve
as the basis for project decision-making.”
The 2012-2013 exploration work done by Graphite Australia was reviewed and
completed by AEMCO in 2015 and 2016 and from this review a maiden JORC
2012 resource was determined.

Geology The Munglinup area comprises Archean to Paleoproterozoic, metamorphosed
granitic and other metamorphic rocks of the Albany–Fraser Orogen, typically
hornblende (± garnet) gneiss and migmatite.
Within the gneissic rock mass, rocks containing the Munglinup graphite
deposits consist of a succession of tightly folded metasedimentary rocks with a
consistent dip from north north east to the south.
The classification scheme most widely accepted for graphite deposits was
introduced by Cameron (1960). It classifies known graphite deposits into five
categories reflecting the different types of graphite.
Using this classification scheme, it is most likely that the Munglinup deposit
can be characterised as a type 1, disseminated flake graphite in silica-rich
meta-sediments deposit.

Criteria Commentary
Database integrity Data is currently stored in a secure third party (Maxwell Geoscience) cloud
hosted and maintained geological database solution (WebShed). A review of
the data was done by the project field geologist Mr. Luke Forti and the
accuracy of the data was discussed with him during a number of meetings with
AEMCO during 2015. Confirmation on the integrity and accuracy of the data
was provided.
A visual review of the diamond core was then done by AEMCO in 2016 to
confirm the historical logging by Graphite Australia. Any outstanding
information was recovered from the diamond core and updated geological
logs were created.
Diamond core was relogged and resampled in 2016. 422 core samples were re-
analysed by Nagrom during April 2016, including 26 duplicate and 19 repeat
samples to confirm grade results. GGC01, GGC08 & GGC09 standards were
used.
The data and results obtained from the 2012-2013 (Graphite Australia) drilling
campaign were compared with the new logging and lab results from 2016
(AEMCO) as well as the historical logging and grades from the 1986 diamond
holes by Sons of Gwalia. Any discrepancies or errors were either corrected or
the results rejected.
Site visits No site visit was undertaken as all drilling, survey work and site rehabilitation
had been completed before this resource assessment started.
Geological The overall continuity of the graphitic schist is very strong yet local geometric
interpretation complexity can be high.
Geological logging, and to a minor degree assay, have been used to generate
estimation domains. Unassayed intervals have been set to zero before
estimation. The minimum interpreted thickness of mineralisation and internal
waste was 1m.
The strike and dip of the deposit is well understood. The mineralisation is
sometimes tabular but can also be geometrically complex. Mineralisation
pinches and swells and bifurcates. There may also be small scale faulting and
faulting which is still not well understood and, while probably not impacting on
global tonnes and grade, can impact significantly on the local geometry.
Dimensions The mineralised zones consist of numerous thin (2-20m wide) steeply dipping
folded zones reflecting a cover nappe system with late stage granite and
pegmatite intrusions.

considered to be approximately 7-10% TGC. The cashflow model developed
for mine optimisation included some blocks as low as circa 6% TGC as
economic, given favourable metallurgical response estimations and material
location (i.e. short haul distances).

Bulk density The bulk density is based on historical density calculation for the material at
2.0 g/cm3
The host geology comprises weathered metamorphic material. Visual
inspection of core indicates little loss of material due to vugs or discontinuities.
All material within the mineralisation domains were assumed to be a
combination of graphitic gneiss, graphitic ironstone and graphitic magnesite.
Classification Classification is Indicated for 40m spaced drilling.
Inferred resources are up to 100m from the nearest drill hole but extrapolation
distances of 30-50m would be more common. Inferred resources are generally
in areas where the mineralisation is considered thicker and more continuous.
These resource classifications are considered appropriate by the competent
person for the style of mineralisation and quality of data.
Audits or reviews No formal review or audit of the Mineral Resource model has been completed.
The model was informally reviewed by Mr. Andrew Scogings of CSA Global
who is a highly experienced geologist with expert knowledge of industrial
minerals exploration, mining and processing, product development, market
applications and commercialisation processes. Andrew has published several
papers on the requirements of JORC 2012 Clause 49 and is an AIG Registered
Professional Geologist specialising in industrial minerals.
Discussion of The Munglinup graphite deposit has been mapped, drilled, mined and
relative accuracy/ investigated numerous times over the past 100 years. The high-grade nature of
confidence the resource and its potential is well documented.
While large scale continuity of the mineralised domain is good, variogram
ranges are short and local estimation accuracy is often low.
The resource estimate compares favourably with historical production grades
of 19%.
Conditional simulations of total graphitic carbon were generated in 2019 for
Halberts Main. The indicated resource was divided into three elevation-based
zones each equating to about 12 months production. The uncertainty in
predicted tonnes of graphite was ± 14%. This, however, does not include
uncertainty for the geological interpretation and density which may be
significant.

Site visits Numerous site visits have been undertaken since October 2017. The nearby
Towns of Ravensthorpe and Esperance have also been visited to assess
regional infrastructure and support capabilities. Historical core from the site
has also been examined at various times by both the Mineral Resource and Ore
Reserve CP’s.
Surface mineralisation was examined along with locating of previous drill
collars and review of recent drilling programs while being conducted. Access
and exploration of possible mining issues were assessed along with a general
geographic overview of the area.
Study status This study is assessed as being at a Definitive Feasibility Study Level.
Historical study work on the Munglinup Deposit is extensive.
The Definitive Feasibility Study evaluated Geology and Resource, Mining,
Metallurgy, Process Plant and Tailings, Infrastructure and Logistics,
Environment and Permitting, Human Resources, Marketing, Implementation
Plan and Schedule, Capital and Operating Costs, Financial Assessment, Risk
Management and other activities/issues that could impact the proposed
operation as contained in the DFS report.
Criteria Commentary
The Definitive Feasibility study considered the technical, engineering and cost
components, as well as the health and safety, and social and community
impacts
Metallurgical test work shows that an acceptable minimum level of recovery
and concentrate grade can be obtained with confidence.
Cut-off A simplified cashflow script was developed to generate at a block level all of
parameters the required attributes to calculate the cashflow grades for the proposed
processing permutation for subsequent use in pit optimisation and strategic
mine schedule optimisation.
The basis for the application of the cut-off grade is a simplified variable cash
flow per tonne. This approach provides the most mathematically efficient
inputs to solve the objective function as used consistently in the optimisation
models developed, which is to maximise the real, pre-tax NPV.
The cash flow script provides the linkage between the block model, the
metallurgy models and the scheduling models and therefore needs to
accurately reflect the input assumptions. The cash flow script, and the cash flow
grade which it generates is current industry best practice, and supersedes other
forms of cut-off grade such as a graphite break-even estimation as used in the
historical studies.
The cash flow script was built with the current economic assumptions to
accurately reflect the proposed operating cost profiles. The throughput and
recovery calculation steps were based on the ALS testwork throughput and
recovery estimations.
Blocks where the cash flow per tonne is positive are designated ore and
negative blocks designated waste.
Mining factors or The pit shells were developed in Whittle 4x using the variable cashflow cut-off
assumptions grade estimated in the block model. The optimisation shells selected
comprised 13 open pits, mined over 2 stages, which initially target the higher
value areas earlier in the mining plan. The stage 1 pits are optimised on the
Measured and Indicated material while stage 2 optimisations include Inferred
material.
A revenue factor of 1 was used for the stage 1 shells and 0.45 was used for the
stage 2 shells. The lower revenue factor used in the stage 2 shells was deemed
appropriate given the lower geological confidence. This resulted in selection of
inferred material that is likely well above the cut-off grade and robust in terms
of remaining economic within the variability of other modifying factors.
Dilution was set to 5% and ore recovery at 3%
All the selected pit shells had detailed pit designs created which aligned with
the shells while retaining the geotechnical recommendations provided by
Mining One.
The deposits will be mined in multiple stages using conventional open pit
operation and will utilise conventional load-haul mining methods. Each bench
will be mined using 130 tonne to 150 tonne class excavators and 100 tonne
class rigid frame trucks.
A minimum mining width for pits of 35 meters based on the use of CAT 777
class rigid frame trucks.
Haul road widths designed to 22m for dual lane traffic and 15m for single lane,
based on the use of CAT 777 class rigid frame trucks, with all ramp gradients to
be limited to 1:10 (10%).
Criteria Commentary
Mineralisation extends to surface so only limited pioneering and soil collection
works are required. There is no pre-strip.
The high-grade nature of the deposit results in pit optimization shell sizes
increasing incrementally with revenue factor.
Access to the area is straight forward with council maintained roads available
to within 2 kilometers of the mining area.
The topography is gently undulating rises and it is anticipated that no
significant issues associated with mining are likely.
Historical work included a systematic examination of drill core to assess the
requirement for drill and blast during mining and to assess open pit stability.
The examination was based largely on RQD parameters and concluded that
drill/blast of the ore zone was unlikely to be necessary or desirable. Drill and
blast of the west wall gneiss may however be required at depth. This has been
costed in the contract mining proposals but not included in the financial model
at this stage. Further detailed work on material hardness at depth will be
conducted when appropriate.
Infrastructure requirements for the selected mining method are minimal.
Annual material movement is planned to be limited to 3.5Mt per annum for the
first 3 years of operation then reducing to a maximum of 3Mt per annum.
This level of mining activity is minor and will only require the most basic of
infrastructure such as a small workshop, office, crib and ablution block and
equipment hard stand.
The average strip ratio is 5:1 (waste:ore).
Based on the block model, the total mined mine waste rock volumes are
expected to be approximately 35.3 million tonnes over a 15-year mine life. This
equates to 19.3 million cubic meters of loose material at an average in-situ
bulk density of 2.45 and a swell factor post mining of 35%.
Halbert’s Main will be required for waste dumping once the pit has been
finalised at the end of 2026. Available volume in Halbert’s Main is 6.3 million
cubic meters. Total waste material remaining post completion of the Halbert’s
Main pit is 9.79 million loose cubic meters.
Metallurgical The metallurgical process proposed is comprised of standard graphite flotation
factors or processing. Flotation is a standard processing method for graphite flake
assumptions deposits.
Flotation technology is well tested and understood.
Significant historical metallurgical testwork has been undertaken. Overall,
more than 20 specific metallurgical studies were undertaken on the Munglinup
Graphite mineralisation, predominantly in the late 1980’s and early 1990’s. In
2017 a metallurgical testwork program was undertaken at ALS Laboratory (ALS)
in Perth to assess the ore’s amenability to beneficiation by gravity and froth
flotation. The results from this testwork program were used to support the
process design and engineering for the 2017 PFS. In 2018 and 2019 further
drilling was conducted to generate samples for additional metallurgical
testwork programs to support the DFS.
An 8t bulk sample was extracted from the Halberts Main deposit to be used for
metallurgical test work undertaken by Nagrom in 2011. This sample does
include material from the three mineralisation types. The sample has ultimately
been deemed only partially representative as it does not include material from
depth. Future metallurgical testwork is utilizing a master composite derived
from historical drilling core and that has been selected to provide high
representivityof the deposit.
Criteria Commentary

The 2018 PFS testwork utilised core that had been drilled in 2013 in Halberts
Main and Halberts South areas. The variability program utilised core from
eight drill holes from the 2018 program, located at Halberts Main and Halberts
South at varying depths and lithology.

Comminution testwork was undertaken on the Master Composite, near surface
scrubber feed samples that were relatively soft, and additional samples
targeted to provide more spatial variability as well as more competent material
based on visual selection of the core. The tests included:
o
SAG Mill Comminution test (SMC)
o
Bond Ball Work Index (BBWi)
o
Bond Rod Work Index (BRWi)
o
Bond Abrasion Index (Ai)

The ore is naturally very friable, weathered and can generally be considered to
be soft.

Initial flotation testwork was undertaken on the variability composites of
Halberts Main and Halberts South at varying depths and lithology. The TGC
recoveries were variable ranging from 56.0 to 97.5 % within the distribution.
The composites withpoor recoveries were either those in the ironstone-rich or

  • near surface zones. A size analysis of the final concentrates showed that all these composites contained little amounts of coarse flakes with most of the material in the -75 µm size fraction.

  • The feed size P100 of 1000 µm was selected as the primary grind for the rougher circuit. Generally, the test procedure involved desliming the ground material at 25µm followed by rougher flotation. The rougher concentrate then underwent a secondary grind, as there were some coarse composites that needed to be liberated, before undergoing multiple cleaning stages. Prior to each cleaning stage the concentrate was reground in a stirred mill using ceramic media. This procedure aimed to increase graphite particle liberation whilst trying to avoid the break-up of coarser flakes.

  • The flotation reagent scheme was relatively simple, consisting of kerosene as the collector, and a frother. All flotation tests were carried out at natural pH.

  • The TGC recoveries were variable ranging from 56.0% to 97.5 %. The results showed that the high-grade final concentrates can be consistently produced with TGC grades ranging from 95.0% to 98.3% after 5 stages of cleaner flotation.

  • The results showed that the coarse flake fraction (+150µm) can be maintained at around 50% proportion of the concentrate at high average TGC grades (up to 97.7%) and that high-grade fines (-150µm) concentrate can be produced with up to an average of 98.3% TGC.

  • In 2019 further drilling was conducted to generate samples for a metallurgical testwork program to support the DFS.

  • A DFS Master Composite was produced and test work focused on optimising the flake size distribution and final grades of the concentrate. The testwork also investigated adjusting reagents addition rates, the number of cleaning and recleaning flotation stages, the number of polishing grinds, alternate reagents and intermediate screening. Processing was generally in Perth water with additional tests conducted using site water.

  • A 480 kg bulk sample of the DFS Master Composite was prepared and underwent large batch flotation tests in order to produce concentrate for vendor and marketing purposes. The flotation scheme and was based on the optimisation test work and utilised larger laboratory equipment. The coarse flake fraction was contained 48.6% of the mass with a TGC grade averaging 95.8%. The fines accounted for 51.4% of the mass with a TGC grade averaging 96.0%.

  • Test work also included scrubbing, thickening, filtration, and rheology.

  • Thickener testwork results indicated that both tailings and concentrate can be thickened by high rate thickening over a range of fluxes. The tailings reached densities up to 50.2% solids (w/w) while the final concentrate reached densities up to 36.8% solids (w/w).

  • Comparative filtration testwork found that the most efficient method was pressure filtration over vacuum filtration. A final cake moisture of around 15% w/w was achieved with extensive air blowing.

  • Graphite flake size distribution is set using a Rosin-Rammler Regression model.

  • Analysis of the variability test work data shows that the n (dispersion) parameter on the Rosin-Rammler TGC feed distribution is a good predictor of the TGC Recovery.

Criteria Commentary
The distribution was also used to determine the product flake size distribution.
This estimation also correlated well with the variability test work data.
No specific allowances have been made for deleterious elements. Any non-
graphite material that reports to the graphite concentrate is deemed to be
dilutionary in nature only and does not attract any specific penalties beyond
the reduction in concentrate price based on the graphite concentrate purity as
is standard in the industry.
Both historical and recent work has been done on the mineralogy of the
deposit. The latest petrographical study was conducted on 12 samples from
drill core that are representative of the deposit. The petrographical nature of
the graphite mineralisation at Munglinup is well understood and shows that
the final product will be able to meet the required specifications
mineralogically.
Environmental Significant environmental assessment work has been undertaken. The deposit
lies entirely within a granted mining lease and information from the DMR
suggests that only limited additional information will be required to proceed
with operations.
The potential mine waste associated with the Project is dominated by Non-
Acid Forming (NAF) and uncertain material, a small proportion of the waste is
Potentially Acid Forming (PAF). The PAF material will need to be managed
during operations. The Project wastes were also found to contain metals above
local soil concentration that can be potentially harmful to the environment
such as arsenic, copper, lead, nickel and zinc, however only copper, nickel and
lead are of concern and may require specific management during operation
and closure. No metals were found to exceed health investigation level. All
materials tested were found to have Exchangeable Sodium Percent (ESP) values
>15% indicating that the wastes are strongly sodic and potentially dispersive.
Flood assessments for a 1-in-100 and 1-in-2000-year flood events are not
envisaged to impact on the Project, with the exception of a small creek line
adjacent to the Halberts Main pit
Results of geochemical characterisation associated with two tailings solids and
one tailings liquor. The results indicate that the Munglinup tailings are
Potentially Acid Neutralising (PAN), and that Molybdenum and Selenium are
potential constituents of concern in leachate from drytailings.
Criteria Commentary
Seven soil types have been identified and mapped within the Project area. The
majority of soil types within the Project are nutrient deficient, and typically very
shallow (2-5cm) with an organic material layer which included leaf litter and
degrading material with topsoil. Four of the soil types show high exchangeable
sodium percentage (ESP), and have a higher clay content and high sodium
levels, which indicates that these soils are potentially dispersive (ISPL 2018). The
most common soil type within the Project area is the Brown Loam Duplex, with
the majority of available growth medium likely to come from this soil type (ISPL
2018).
The Project lies within the Esperance Coast Topographic Drainage Division and
the Munglinup River sub-catchment, with drainage trending southwards via
two main features, the Munglinup River and its tributary, Clayhole Creek.
A Munglinup River Assessment Report was completed by Wetland Research
and Management in 2018. Concentrations of heavy metals are mostly below
the limit of detection and are not of ecological concern.
Two vegetation survey have been completed over the proposed Project area,
one by Ecologia Environment in 2014 and the second by Woodman
Environmental in 2018
In 2018, a Phytophthora Dieback assessment was completed within the main
Mining Area. This assessment found no Phytophthora Dieback infestations,
however the majority of the vegetation within the Project was mapped as
uninterpretable due to an insufficient coverage of reliable indicator species
(Glevan Consulting 2018).
No known groundwater users are expected to be impacted by the Project
groundwater abstraction.
Three fauna surveys have been completed across the Project Area, one in 2014
by Ecologia Environment and two by Red Dog Environmental in 2018. Field
records from fauna surveys and database records determined the 85 fauna taxa
were recorded from direct sightings and indirect evidence (scats, tracks and
calls). Two conservation significant species have been recorded in the area, one
an endangered species - Carnaby’s Black Cockatoo and the second a priority 4
species – Quenda.
Infrastructure The mining lease is currently devoid of any structures or buildings. Access to
the site from Munglinup township, 4km to the south, is by gravel road either
from the west across the Munglinup River or by station tracks from the east.
Both access roads are in need of an upgrade.
The power requirements for the main process plant have been calculated at a
total connected load of 5.3 MW including all duty and standby equipment with
an estimated average demand of the project being 2.5MW with a peak of
2.8MW. This running load was determined from the estimated plant load plus
allowances for losses.
Power is proposed to be supplied by POWERWEST with a 4.0 MW power
station comprising 4 x containerised Jenbacher J320 - 1,057kWe reciprocating
generator sets (gensets) operating with an n+1 strategy. The power station will
supply power to the plant at 415V.
The power station will be fuelled by liquefied natural gas (LNG) supplied by
EVOL LNG (a division of Wesfarmers), based on an onsite storage and
vaporization facility comprising a single 135 tonne LNG storage tank,
associated ancillary equipment and telemetry systems with a storage capacity
design allowance of a nominal 10-11 days.
Criteria Commentary
The Project will transport product via road train combinations travelling 610 km
from the Project via a third-party logistics provider (3PL) for storage, handling,
packing of containers for export, and delivery to the Port of Fremantle (POF).
Product will be loaded into bulka-bags with a nominal weight of one tonne
prior to transport via tautliner trailers. Approximate product weight per trip is
60-65 metric tonnes.
The Esperance-Goldfields region has a deep pool of mining trained employees
engaged primarily in the gold sector but also in other mining projects. It is
planned that employees will be recruited to a base location in Esperance.
The Project is located approximated 105 km west of Esperance. Site access is
proposed via the South Coast highway;
o
North on Farmer Rd - 8.8 km
o
West on Clayhole Rd - 3.6 Km
o
Primary site access eastern road – 6 km
o
Secondary site access western road
The new site access roads will be constructed in accordance with appropriate
Restricted Access Vehicle (RAV) requirements. In addition, both Farmer and
Clayhole roads will be upgraded as required to comply with RAV road
standards.
A borefield location has been investigated with several production bores drilled
and pump tested to ensure that the borefield will support the operation.
Water from the bores will be pumped to the raw water storage.
Generally, the project benefits from excellent infrastructure requiring only
minimal additional expenditure.
Tailings will be thickened and pumped to a conventional paddock type TSF.
The TSF will require storage of approximately 5.25 Mt of non-acid forming
tailings produced at a rate of 0.35 Mtpa for a design life of 14 years.
The stability analysis of the Munglinup Graphite TSF embankment was carried
out using the 2D limit equilibrium slope stability analysis software SlopeW
(Geostudio 2018). Models were constructed for sections through both the
South Western corner and Western embankments. Two representative cross-
sections were analysed using the Morgenstern-Price method. The results of
the stability analyses indicate that the estimated Factor of Safety against failure
is greater than the Australian National Committee on Large Dams (ANCOLD)
(2012) recommended minimum values.
A simplified dam break flow path assessment and hazard categorising was
carried out for the TSF. The TSF is classified as a Category 1 dam according to
DMIRS (2013). This classification is based on a High C hazard rating as defined
in ANCOLD (2012b) and an embankment height greater than 15m.

Revenue factors

Revenue from the project is derived from the sale of graphite product.
Testwork has established that the Munglinup graphite product can be
produced at a minimum of 94% graphite and, if produced to a minimum of
94% graphite in product, can expect to receive premium or near premium
pricing levels.

Head grade delivered to the processing plant was derived from the underlying
block model. A calculated recovery was used based on previous metallurgical
testwork.

Testwork to date shows that there are no by-products, co-products or
deleterious elements in the concentrate.

Revenue estimates are based on independent market pricing and life-of-mine
concentrate production of 745,022t at an average 52,000 tpa of production.

Prices are expected to rise in the long-term with rapid growth in demand from
the lithium-ion battery industry underpinned by uptake of electric vehicles and
energy storage systems.

The basket price used in the model has been calculated based on pricing
obtained from Roskill Information Services Ltd’s latest market report: “Natural
and Synthetic Graphite: Outlook to 2028, 12th Edition” (“Roskill Report”).

Forecast prices (real) for natural flake graphite (94-97% carbon) 2018-2028 for
fine, medium and large flake were incorporated into the model.

Graphite prices were modelled from 2029 onwards in line with the 2028
forecast.

Prices for small flake product were modelled conservatively to largely reflect
fine product pricing.

Prices for jumbo size flake graphite carry a 50-100% price premium over the
published price of 94-97% carbon large size flake, with a 75% premium
modelled.
  • Criteria Commentary  Super jumbo products have been modelled with a further 40% premium on jumbo product.

  • Revenue estimates are base case only, reflecting average graphite grades of 95%.

  • MRC will continue test work to optimise grade performance towards 99% carbon concentrate production. Per the Roskill Report prices of 99% carbon grade flake typically attract 55-65% higher prices than those of 95% carbon, representing significant upside to MRC.

Market
assessment

Graphite, a form of pure Carbon, has two main types - Natural and Synthetic.
The combined Natural and Synthetic graphite has a market size of some 2.52
million tonnes (2018). Natural graphite accounts for 38% of this market.

The graphite market is an opaque market where most information is not readily
available and market analysis is based on some available data combined with
estimations.

Production of Natural Graphite, including all three forms of it (Amorphous,
Flake, Vein), is 0.95 million tpa.

China, with 60% share, is the biggest producer and seller.

The refractory market still has the biggest share in graphite consumption and
graphite mainly goes into Magnesia Carbon bricks for iron and steel
production. It is estimated that around 0.5 kg of natural graphite is consumed
per tonne of steel, besides the given market share of 28%. In reality it is
estimated that refractories consume 600,000 tonnes of graphite every year.

Total graphite market size could be beyond what was reported. It should be
also considered that different graphite types could potentially substitute each
other, and natural flake graphite is the only graphite type that could possibly
substitute all other types of graphite, including synthetic graphite.

Battery markets, especially Lithium-ion Batteries, represent the fastest growing
market and their main demand driver is Electric Vehicles.

Both synthetic and natural graphite are mainly used as anode material in LiBs.

Natural graphite requires spheroidization, purification and coating processes
before being used in batteries.

To produce one tonne of natural spherical graphite, an average of two tonnes
of natural graphite concentrate is required, mainly because of the rejection of
non-spheroidized material during the process.

Natural spherical graphite and synthetic graphite are generally used together
in the LiBs, with a mixture of 60% natural and 40% synthetic.

It is also estimated that 1 kgofgraphite is required for each 1kWh of batteries.
Criteria Commentary
Global production of LiBs was some 146 GWh in 2018. Roskill forecasts this
level to grow to some 1,771 GWh in 2028. As a result, the demand for graphite
is forecast to grow substantially.
Roskill forecasts that demand for natural graphite will grow from 947kt in 2018
to 1,686kt in 2028 – a CAGR of some 5.9% p.a.
Prices for natural graphite with higher carbon content declined through the
second half of 2018 and into 2019 with increasing supply, mainly from Africa,
and a temporary slowdown in demand for lithium-ion batteries. Despite the
decline they remain relatively high when compared to recent protracted lows.
Growing supply coupled with existing overcapacity in China is expected to
push prices even lower through 2019. More supply will be available to come
online through the early 2020s from the ramp-up/expansion of existing
operations and potentially from some of the new projects currently under
construction, although start-ups will likely be hindered by the current climate
of weakening prices.
Such is the high level of forecast demand from lithium-ion batteries, however
that prices could begin to strengthen again as early as 2021-22 with the market
becoming tight in specific grades preferred for use in batteries.
Rising prices through the early 2020s could encourage a second wave of new
projects, many of which are already well developed and might take it into
production with the correct investment and offtake contracts in place. The
release of new supply into the market could then result in a downwards
recovery in prices towards 2028.
Based on MRC’s market approach, the main focus will be:
o
Possible value additions to our product, producing high purity
graphite, developing expandable production etc
o
Specialty product markets, targeting Alkaline batteries, Lubricants,
Powder Metallurgy, Conductive additives, etc
o
Diversified and customer specific products, closely engaging with
customers and developing the right products for the customers’
requirements
o
Total value proposition: packaging, logistics, offering short delivery
times, fast response times, consistent quality etc
Short-Term (1 to 3 years) – Selling concentrates with the highest possible price
and developing value-added products and markets. Expansion could be
considered in the short-term
Mid-Term (3 to 7 years) – Supplying the value-added product market (BAM)
Long-Term (>7 years) – New and downstream products (graphene for energy
storage, coated spherical graphite etc).
Economic A discount rate of 7% (real). The discount rate applied reflects the weighted
average cost of capital expected from debt funding the project.
Sensitivities of the NPV to changes in key assumptions have been analysed.
These were run on the following key model assumptions: flake graphite pricing,
flake graphite recovery, exchange rate, discount rate, operating costs, capital
costs and construction schedule (capex timing).
In each case, the sensitivities run were regarded as a possible downside
scenario and a possible upside scenario based on the historic experience of
mining projects.

Commentary

==> picture [330 x 132] intentionally omitted <==

  • The upside case for the flake graphite pricing forecast (120% base pricing forecast from Roskill) demonstrates a post-tax NPV at US$174M. The downside case (80% base pricing forecast from Roskill) demonstrates a posttax NPV of US$48M.

  • All cashflows have been prepared in real terms, assuming 2019 dollars, with no inflation of graphite concentrate prices.

  • Social  ML74/245 is a mining lease in the Esperance area granted on 26 August 2010 for a term of 21 years, expiring on 25 August 2031.

  • There are no plaints of other applications currently registered with respect to the tenement and no native title claims.

  • The tenement is in a Mining Reserve specifically set aside from agricultural release. The surrounding land use is primarily farmland. Proximal to mining lease 74/17A are reserves set aside for timber, recreation, water supply, parklands (recreation) and rubbish disposal.

  • An Archaeological Heritage survey across M74/245 identified five archaeological features, two ethnographic features and an additional 35 isolated finds. Following submission to the Department of Planning, Lands and Heritage (DPLH) for assessment, the Munglinup River (Site Id 37695), Mungan Wilgie Koort (Site ID 37631) and Munglinup Standing Stone (Site Id 37798) were registered as an Aboriginal Site (Applied Archaeology Australia 2018).

  • The two ethnographic features lie outside of the required Munglinup development envelope.

  • A section 18s application was submitted to the ACMC and subsequently granted to enable development of the project in areas registered as Aboriginal sites.

  • The Munglinup deposit (Munglinup) is located with the Shire of Esperance, a predominantly rural area with a population in the order of 14,242 residents. The closest town to the Project is Munglinup, which is 4km to the south. Esperance is the main town and administrative centre for the region, located approximately 105 km to the east.

  • Whilst the Munglinup operations will be new, the local community is generally familiar with the characteristics of mining, processing and product transport, as other resource extraction operations occur within the Shire. Stakeholder consultation conducted to-date has identified that the majority of the community are supportive of the Project. During the public consultation period for the Project referral, four submissions where received, suggesting that the community is not concerned about the Project.

Criteria Commentary
Other The Company is currently undergoing review of the environmental impact
submission by the EPA and EPBC under an accredited process to gain an
environmental operating permit.
As there is a Mining Lease in place, no economic evaluation or justification is
required.
Classification The current Mineral Resource classifies all mineralisation at Munglinup as
Indicated and inferred only.
Given predominantly the proposed mining rate and uncertainty of
mineralisation at the local scale, no measured material has been defined under
the JORC guidelines.
Currently, 100% of the Ore Reserve has been derived from Indicated Mineral
Resources.
A comprehensive resource development and grade control drilling program
has been developed and is planned for execution upon granting of project
environmental permits.
Pit optimisations and the proposed mining schedule are cognisant of the
Mineral Resource classification.
The first 6 years of ore feed is almost entirely classified as probable with the
current schedule, including inferred material as “In-Pit Resources” in later years
of production. The inferred material will be upgraded to indicated or
measured prior to the third year of production.
