Tropicana partners AngloGold Ashanti and Independence Group commit to Long Island

(Perth) -- AngloGold Ashanti Australia Ltd (AGAA) is pleased to announce that the Tropicana Joint
Venture has approved Phase One of the Long Island strategy, increasing production from the mine in
the medium term and extending mine life.

Long Island has been driven by developing a more cost-effective way to mine waste. It involves using
a strip-mining approach that minimizes waste haulage distances by using in-pit backfill, rather than
trucking the material long distances to surface waste dumps.

The Tropicana Gold Mine, located 330 kilometers east-northeast of Kalgoorlie in Western Australia, is
owned by AGAA (70% and manager) and Independence Group NL (30%).

Phase One of Long Island comprises mining of the Havana South pit and a cutback of the Boston
Shaker pit, which utilizes the completed Tropicana pit as the first backfill location.

The full Long Island strategy adds 2.1 million ounces to Tropicana’s business plan, extending mine life
by approximately seven years to 2027. The project value has been enhanced by the decision to install
a 6MW ball mill in the processing plant, enabling throughput to be matched to the increased mining
rate and improving gold recovery by up to 3% to approximately 92%.

Grade streaming, which prioritizes the processing of higher-grade ore and stockpiling lower-grade
material for processing at a later date, has resumed at Tropicana and will continue through 2018 and
2019. Gold production (100%) is forecast to be between 478,000oz and 492,000oz next year and
between 530,000oz–548,000oz in 2019.

“This project is in line with our approach of developing cost-effective brownfield projects with attractive
payback periods that extend life and improve margins,” said Michael Erickson, AngloGold Ashanti’s
Senior Vice President Australia. “The project validates the innovative ideas developed by our site
team and technical specialists, and also gives us an excellent base from which we can investigate
adding additional value through underground mining opportunities and regional exploration.”




                                                                                                          1
Gold production over Tropicana’s remaining life of mine is now forecast to be about 4Moz. This does
not include potential future underground production from mineralization at the Boston Shaker ore
body, which remains open at depth. A scoping study will lead into a pre-feasibility study on
underground mining in 2018.

The Long Island strategy is underpinned by continued exploration success, evidenced by another
increase in the Ore Reserve to 66.59 Mt grading 1.91 g/t for a total of 4.08 Moz. This represents an
increase of 280,000oz over the past year, even after depletion of about 550,000oz is taken into
account.

Including gold produced to date, Tropicana has delivered a 72% increase in Ore Reserves since the
Tropicana project was approved in November 2010. (Full Ore Reserve and Mineral Resource
information can be found in Appendix B).

Long Island strategy

As part of the cost-effective strip mining approach, waste haulage distances are reduced by using in-
pit backfill. After initially considering mining a starter pit at Havana South to act as a void for waste
from the proposed pit cutbacks, it became apparent from drilling that because there was limited
upside beneath the Tropicana pit, it would provide significant value as a backfill location.

As previously reported, the Long Island concept provides optionality and flexibility, with eight mining
stages and three decision points (see Figure 1 in the full announcement on the AngloGold Ashanti
website: http://www.anglogoldashanti.com/investors/announcements/) giving the opportunity to adjust
to changing economic conditions. If all three phases are implemented mine life will be extended to
2027.

Mining rates at Tropicana have been successfully increased over the past year to more than 90 Mtpa
with the addition last year of a 600 tonne face shovel, de-risking the increase to the Long Island
mining rate of between 95-107 Mtpa. The mining rate will peak at 107 Mtpa in 2019 and continue at
that rate for about four years until the bulk of the Havana pit is mined.

To achieve the additional material movement increase, a second 600t shovel with up to five additional
Caterpillar 793 trucks and supporting ancillary equipment, will be added to the fleet. The capital
expenditure related to Long Island will be approximately A$18 million, primarily for expansion to the
accommodation camp and heavy vehicle workshop infrastructure.

The additional fleet will be provided by Macmahon Holdings as part of the mining contract at the site.

Productivity improvements through AGA’s Operational Excellence programme have resulted in a
reduction in mining costs at Tropicana over the past two years to A$3.07/t using conventional mining
methods. It is anticipated that ongoing mining efficiencies will further reduce mining costs by 5-10%
during Phase One.




Boston Shaker drilling and underground PFS




                                                                                                            2
Diamond drilling beneath the Boston Shaker pit in the second half of 2017 has returned encouraging
intercepts including: 18m at 6.58 g/t from 587m depth (BSD087W1), 37m at 6.49 g/t from 509m
(BSD088); and 20m at 5.82 g/t from 609m (BSD089AW2). See Figure 2 and Figure 3 and detailed
table of intercepts in Appendix A of the full announcement on the AngloGold Ashanti website:
http://www.anglogoldashanti.com/investors/announcements/.

Step out holes BSD090 and BSD091A have confirmed mineralisation up to 1,000m down dip of the
Long island pit design.

Evaluation of open pit grade control drilling shows strong grade continuity in the Boston Shaker
southern ore shoot. This, combined with the thick zones of high-grade mineralisation identified in
recent exploration drilling, suggests the Boston Shaker ore zones will be amenable to underground
mining.

Following a scoping study, which is currently underway, a pre-feasibility study will be carried out in
2018 to investigate potential for underground mining at Boston Shaker with the aim of defining an
underground Ore Reserve by the end of the calendar year. The PFS will include infill drilling and
mining studies.

Successful development of an underground mine at Boston Shaker has the potential to contribute
high grade ore to the processing plant from 2021 onwards.


Approval of additional ball mill

The installation of a second ball mill in the Tropicana processing plant grinding circuit has been
approved. The 6MW ball mill will enable the annual throughput rate to be lifted to approximately
8.1Mtpa and through a reduction in grind size, baseline metallurgical recovery will be improved by up
to 3%, to approximately 92%.

The increased throughput will efficiently match processing capacity to the Long Island mining rate,
and effectively bring forward gold production delivering the best production profile for the operation.
The improved recovery rate will add approximately 160,000 oz to recovered gold over the life of mine.

Total capital expenditure is anticipated to be A$28 million (100%) including equipment, construction
cost and spares, and the new mill is scheduled to be commissioned in Q4 2018. The site has
adequate power generation capacity to cater for the additional mill and no further infrastructure is
required.

Based on mill throughput of 8.1 Mtpa and a recovery improvement of 2.7% in the first year the
payback period will be less than a year.

The additional ball mill follows a range of expansion and optimization projects that have lifted the
throughput rate at commissioning from a nameplate 5.8 Mtpa to approximately 7.6 Mtpa by the end of
2017.

A fines pulping circuit was commissioned in November this year, further improving efficiency and
throughput by minimizing downtime during maintenance shutdowns.



Regional Exploration




                                                                                                         3
Regional exploration at Tropicana in 2017 has been guided by new thinking and work completed
through 2016.

Palinspastic reconstruction and a geological review have provided an updated understanding and
revised interpretation of the regional geology and prospectivity in the belt. The evolution of this work
continues, with inputs from current exploration drilling and further specialist and academic work.

In 2017, a balanced strategy was adopted, comprising resource development at Tropicana, and early-
to-advanced stage exploration regionally.

Advanced exploration continued to evaluate existing prospects (Madras, Voodoo Chile, Angel Eyes,
Springbok) and test the New Zebra anomaly identified through aircore drilling in late 2016. Early stage
aircore drilling was carried out at Chocalatini, Iceburg, Caprioska and Watchtower.

Following highly encouraging results at Boston Shaker in 2017, priority was given to resource
development drilling to evaluate underground potential. This focus will continue in 2018 along with
regional exploration to test new targets identified as a result of the palinspastic reconstruction.


Ore Reserve and Mineral Resource update

As part of the Long Island study a total of 193,554 metres of drilling was carried out between 2015
and 2017 to test the down-dip extent of the Tropicana Mineral Resource at Havana South, Tropicana
and Boston Shaker.

This delivered an increased Mineral Resource which formed the foundation of the Long Island study.

The Ore Reserve (as at 31 December 2017) has increased by 820,000 oz, net of depletion, since 31
December 2016 as a result of the incorporation of Boston Shaker 03, Boston Shaker 04 and the
revised Havana South.

Section 1 Sampling Techniques and Data

           Criteria                                                                           Commentary
 Sampling techniques                     - AngloGold Ashanti Australia (AngloGold) has used drilling and sub-sampling of the cuttings or cores as the data
                                           basis for the Mineral Resource estimates of the Tropicana deposit. Details are given in the following subsection.
                                         - Drill hole spacing ranges from 25m×25m grids to 100m×100m grids, with most of the drilling of the Open Pit
                                           Mineral Resources on a 50m×50m spacing with 25m×25m testing the starter pits of the Tropicana and Havana
                                           initial pits, and the southern end of the Boston Shaker deposit.
                                         - A 100m×100m area of Havana was drilled out on a 10m×10m grid to validate the resource model and optimise
                                           the grade control sample spacing.
                                         - The Underground Mineral Resource down-plunge extensions of Havana Deeps is tested using a 100m×100m
                                           grid. Deep +800m deep step-out holes have been drilled on nominal ?200m×100m to test the high-grade
                                           mineralisation of Havana Deeps.
                                         - All holes are drilled plunging towards the west to intersect the east dipping mineralised zones


 Drilling techniques                 - Reverse circulation (RC) percussion drilling using face-sampling bits (5 ¼ inch or 133 mm diameter) has been
                                       used to collect samples from the shallower (up-dip) part of the deposits with a nominal maximum RC depth of
                                       150m.
                                     - Diamond core drilling has been used for deeper holes, with diamond tails drilled from RC pre-collars. To
                                       control the deviation of deep DD holes drilled since 2011, many of these holes were drilled from short ? 60m
                                       RC pre-collars or using 63.5mm (HQ) diameter core from surface.
                                     - Diamond core drilling for Mineral Resource definition is predominantly 47.6mm (NQ) diameter core, with a
                                       lesser number of holes drilled for collection of metallurgical and/or geotechnical data using 63.5mm (HQ2,
                                       HQ3) or 85mm (PQ) core diameters.
                                     - In fresh rock, cores are oriented wherever possible for collection of structural data. Prior to 2009, core
                                       orientations are made using the EzyMark tool with the Reflex Ace Tool replacing the system in later drilling
                                       programmes.

        Criteria                                                          Commentary
Drill sample recovery     -   RC recovery
                               o Prior to 2008 semi-quantitative assessment was made regarding RC sample recovery with recovery
                                   visually estimated as 25%, 50%, 75% of 100% of the expected mass volume of a 1m drilling interval.
                               o Since 2008, AngloGold has implemented quantitative measure on every 25th interval where the masses
                                   of the sample splits are recorded and compared to the theoretical mass of the sampling interval for the
                                   rock type being drilled.
                               o AngloGold found that overall recovery in the regolith was >80% and total recovery in fresh rock.
                          -   DD Recovery
                               o DD recovery has been measured as percentage of the total length of core recovered compared to the
                                   drill interval.
                               o Core recovery is consistently high in fresh rock with minor losses occurring in heavily fractured ground
                                   or for DD drilling in the regolith.
                          -   The main methods to maximise recovery have been recovery monitoring as described above and diamond
                              core drilling below ? 150m depth.
                          -   No relationships have been noted between sample recovery and grade and sample biases that may have
                              occurred due to the preferential loss or gain of fine or course material are considered unlikely.


Logging                   -   RC cuttings and DD cores have been logged recording geological and geotechnical characteristics with
                              reference to AngloGold’s logging standard library, to levels of detail that support Mineral Resource estimation,
                              Ore Reserve estimation and metallurgical studies.
                          -   Qualitative logging includes codes for lithology, regolith, and mineralisation for both RC and DD, with sample
                              quality data recorded for RC such as moisture, recovery, and sub-sampling methods.
                          -   DD cores are photographed, qualitatively structurally logged with reference to orientation measurements
                              where available.
                          -   Geotechnical quantitative logging includes QSI, RQD, and matrix and fracture characterisation.
                          -   The total lengths of all drill holes have been logged.

                          -   RC – Primary splitting
Sub-sampling techniques
and sample preparation         o   Prior to 2007 RC samples were collected from the cyclone stream using a tiered riffle splitter. From
                                   2007 a static cone splitter was introduced and replaced riffle splitters on all rigs.
                               o   The RC sampling interval is generally 1m but from 2016 2m intervals were introduced for RC pre-
                                   collars.
                               o   The splitters collected a ? 12% split from the primary lot with two 12% splits collected – the first for
                                   laboratory submission and second as a reference or replicate. Most samples were collected dry with
                                   <2% of samples recorded as being split in moist or wet state.
                               o   The main protocol to ensure the RC samples were representative of the material being collected was
                                   monitoring of sample recovery and collection and assay of replicate samples.
                          -   DD – Primary sample
                               o   DD cores are collected of intervals determined by geological boundaries but generally targeting a 1m
                                   length
                               o   All NQ cores have been half-core sampled with the core cut longitudinally with a wet diamond blade.
                               o   A small amount of DD whole cores have been sampled from HQ3 cores drilled to twin RC holes in the
                                   regolith or for geotechnical or metallurgical testing.
                               o   In 2005, some 1,150m of cores drilled in the oxide zone were chisel split rather than wet cut but this
                                   poorer sub-sampling represents <0.01% of the core drilled.
                          -   Laboratory preparation
                               o   Sample preparation has taken place at three laboratories since commencement of Mineral Resource
                                   definition drilling including SGS Perth (pre- 2006), Genalysis Perth (2006 to April 2016) and Tropicana
                                   site laboratory (2015 Boston Shaker samples and post-April 2016 samples)
                               o   RC samples were over dried then pulped in a mixer mill to a PSD of 90% passing 75 microns before
                                   sub-sampling for fire assay.
                               o   SGS prepared DD half-core samples by jaw-crushing then pulverisation of the whole crushed lot to a
                                   particle size distribution (PSD) of 90% passing 75 microns. A 50g subsample of the pulp was then
                                   collected for fire assay.
                               o   Genalysis prepared the samples in a Boyd crusher rotary splitter combo with nominally 2.5kg half-core
                                   lots crushed to <3 mm then rotary split to ? 1 kg before pulverisation and sub-sampling for fire assay.
                               o   Samples less with mass <800g submitted to Tropicana laboratory are pulped in a LM2 mill to a PSD of
                                   75 microns before sub-sampling for fire assay. Samples with larger masses are crushed in a Boyd
                                   crusher to a PSD of 90% passing 2mm then subsampled using a linear sample divider.
                               o   From May 2016, a jaw crusher has been used to crush half-core samples to a PSD of 100% passing 6
                                   mm.
                          -   Quality controls for representative sampling:
                               o   SGS inserted blanks and standards at a 1:20 frequency in every batch with a duplicate pulp collected
                                   for assay every 20th sample. Further repeats were also completed at a 1:20 frequency in a random
                                   manner. Sieve checks were completed on 5% of samples to monitor PSD compliance.

        Criteria                                                             Commentary
                                 o    Genalysis inserted blanks and standards in every batch and a duplicate pulp was collected for assay on
                                      every 25th sample and 6% of each batch was randomly selected for replicate analysis. Sieve checks
                                      were completed on 5% of samples to monitor PSD compliance.
                                 o    Tropicana laboratory used barren basalt and quartz to clean equipment between routine samples
                            -   Sample size versus grain size
                                  o   No specific heterogeneity tests have been carried out but the sample sizes collected are consistent with
                                      industry standards for the style of mineralisation under consideration.
                                  o   A 2008 sampling variability study found that 72% of the gold in the samples tested was in size fraction
                                      <300 microns, and that repeated sampling of the same lot have very low variance between replicates.


Quality of assay data and   - No geophysical tools were used to determine any element concentrations material to the Mineral Resource
laboratory tests              estimate.
                            - All Mineral Resource prepared pulps have undergone 50g fire assay which is considered a total assay for
                              gold
                            - As discussed above all laboratories have used industry standard quality control procedures with standards
                              used to monitor accuracy, replicate assay to monitor precision, blanks to monitor potential cross
                              contamination and sieve tests to monitor PSD compliance.
                            - AngloGold has also used other ‘umpire’ laboratories to monitor accuracy including Genalysis Perth (prior to
                              November 2006), SGS (from November 2006 to August 2007) and ALS Perth (since August 2007), with these
                              check assaying campaigns coinciding with each Mineral Resource update.
                            - AngloGold has reviewed the quality sample results on a batch by batch and monthly basis and has found that
                              the overall performance of the laboratories used for Mineral Resource estimation samples is satisfactory.


Verification of sampling    -   Significant intersections of mineralisation are routinely verified by AngloGold senior geological staff and have
and assaying                    also been inspected by several independent auditors as describe further below.
                            -   Twin holes have been drilled to compare results from RC and DD drilling with the DD results confirming that
                                there is no material down-hole smearing of grades in the nearby RC drilling and sampling.
                            -   All logging and sample number data is captured digitally in the field using Field Marshall Software (upgrade to
                                Micromine Geobank in 2016). Data is downloaded daily to the Tropicana exploration server and checked for
                                accuracy, completeness and structure by the field personnel.
                            -   Assay data is merged electronically from the laboratories into a central Datashed database, with information
                                verified spatially in Vulcan software. AngloGold maintains standard work procedures for all data
                                management steps.
                            -   An assay importing protocol has been set up to ensure quality samples are checked and accepted before
                                data can be loaded into the assay database
                            -   All electronic data is routine backed up to AngloGold’s server in Perth and provided to IGO via FTP transfer.
                            -   There have been no adjustments or scaling of assay data other than setting below detection limit values to
                                half detection for Mineral Resource estimation work.


Location of data points     -   All early drill hole collar locations of surface holes have been surveyed using RTK GPS equipment, which was
                                connected to the state survey mark (SSM) network.
                            -   The grid system is GDA94 Zone 51 using AHD elevation datum.
                            -   Prior to 2007, drill hole path surveys have been completed on all holes using Eastman single shot camera tools,
                                with down-hole gyro tools used for all drilling post 2007
                            -   A digital terrain model was prepared Whelan’s Surveyors from aerial photography flown in 2007, which has
                                been supplemented with collar data surveyed using RTK GPS. This model is considered to have centimetre-
                                scale accuracy.


Data spacing and            -  The drill hole spacing nominally ranges from 25mN×25mE to 100mN×100mE (local grid) over most of the
distribution                   Mineral Resource area with a small area of 10mN×10mE used for grade control calibration work.
                            - Most of the Open Pit Mineral Resources has been tested on a 50mN×50mE grid with closer spaced
                               25mN×25mE patterns in the upper parts of the deposit within initial open pit designs.
                            - The Havana Deeps area has been drilled on a 100mN×100mE pattern.
                            - Down-hole sample intervals are typically 1m with 2m compositing applied for Mineral Resource estimation work.
                             - The Competent Person considers that data spacing is sufficient to establish the degree of geological and
                               grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedures applied, and
                               the JORC Code classification applied.


Orientation of data in      -   Most drill hole are oriented to intersect the shallowly east dipping mineralisation at a high angle and as such,
relation to geological          a grade bias introduced by the orientation of data in relation to geological structure is highly unlikely.
structure

Sample security             -   The chain-of-sample custody is managed by AngloGold.

         Criteria                                                             Commentary
                             - Samples were collected in pre-numbered calico bags, which are then accumulated into calico bags for
                               transport from the collection site. The accumulated samples are then loaded into wooden crates and road
                               hauled to the respective laboratories (Perth or Tropicana).
                             - Sample dispatches are prepared by the field personnel using a database system linked to the drillhole data.
                             - Sample dispatch sheet are verified against samples received at the laboratory and any missing issued such
                               as missing samples and so on are resolved before sample preparation commences.
                             - The Competent Person considers that the likelihood of deliberate or accidental loss, mix-up or contamination
                               of samples is considered very low.


 Audits or reviews           - Field quality control data and assurance procedures are reviewed on a daily, monthly and quarterly basis by
                               AngloGold field personnel and senior geological staff.
                             - The field quality control and assurance of the sampling was audited by external consultants Optiro during
                               2017. Optiro rated the standard of work completed as good.




Section 2 Reporting of Exploration Results

           Criteria                                                             Explanation

 Mineral tenement and        -  The Tropical Gold Mine Mineral Resources are located wholly within WA mining lease M39/1096, which
 land tenure status             commenced on 11 Mar 2015 and has a term of 21 years (expiry 10 Mar 2036).
                             - Tropicana Gold Mine in a joint venture between AngloGold (70%) and IGO (30%) with AngloGold as manager.
                             - Gold production is subject to WA State royalties of 2.5% of the value of gold value.
                             - There are no material issues relating to native title or heritage, historical sites, wilderness or national parks, or
                                environmental settings
                              - The tenure is secure at the time of reporting and there are no known impediments to exploitation of the
                                Mineral Resource and Ore Reserve and on-going exploration of the mining lease.



 Exploration done by other   -   AngloGold entered in to a JV with IGO in early 2002 with the main target of interest being a WMC gold soil
 parties                         anomaly of 31ppb, which was reporting in a WA government open file report. Prior to the JV, the WMC soil
                                 sampling program was the only known exploration activity and the only dataset available were WA government
                                 regional magnetic and gravity data.


 Geology                     -   The Tropicana Gold Mine is on the western margin of a 700km long magnetic feature that is interpreted to the
                                 collision suture zone between the Archean age Yilgarn Craton to the west and the Proterozoic age Albany-
                                 Fraser Origan to the east of this feature. The gold deposits are hosted by a package of Archean age high
                                 metamorphic grade gneissic rocks.
                             -   Four distinct structural domains have been identified – Boston Shaker, Tropicana, Havana and Havana
                                 South, which represent the same mineral deposit offset by NE striking faults that post-date the mineralisation.
                             -   The gold mineralisation is hosted by a shallowly SW dipping sequence of quartz-feldspar gneiss, amphibolite,
                                 granulite and meta-sedimentary chert.
                             -   The gold mineralisation is concentrated in a ‘favourable horizon’ of quartz-feldspar gneisses, with a footwall of
                                 garnet gneiss, amphibolite or granulite.
                             -   Mineralisation is characterised by pyrite disseminations, bands and crackle veins within altered quartz-
                                 feldspar gneiss. Higher grades are associated with close-spaced veins and sericite alteration
                             -   Mineralisation presents as stacked higher grade lenses within a low-grade alteration envelope. Geological
                                 studies suggest the mineralisation is related to shear planes that post-date the development of the main
                                 gneissic fabric and metamorphic thermal maximum.

 Drill hole Information      -   A summary of the all drillholes used to prepare the Mineral Resource estimate is not practical for this public
                                 report. The Mineral Resource estimate gives the best-balanced view of all the drillhole information available
                                 as at June, 2017.

 Data aggregation            -   No metal equivalent values are considered in the Mineral Resource estimate.

          Criteria                                                            Commentary
 Database integrity          - AngloGold captures field data and drill hole logging directly in to handheld devices or laptop computers using
                               Field Marshall and Geobank software.
                             - The drillhole data is managed in DataShed software, which is an industry recognised system for management
                               of geoscientific drillhole information. Logging, assays and survey information is loaded directly into
                               Datashed using data import routines, with loading procedures incorporating quality control checking.
                             - Data is validated following loading through visual inspection of results on-screen both spatially and using
                               database queries and cross section plots. Typical checks carried out against original records to ensure data
                               accuracy include items such as overlapping records, duplicate records, missing intervals, end of drillhole
                               checks and so on.


 Site visits                 -   The Competent Person makes regular site visits to Tropicana to review the data collection procedures and
                                 discuss the geology and mineralisation of the deposit prior to any Mineral Resource update.


 Geological interpretation   - To control the Mineral Resource estimation process, three dimensional digital solids were prepared in LeapFrog
                               software for the mineralised zones, dykes, shears and garnet (mostly hanging wall) gneiss.
                             - Mineralised solids were prepared using a nominal 0.3g/t AU drill hole cut-off grade to encompass the gold
                               mineralisation targeted for Mineral Resource estimation. The dykes, shears and garnet gneiss solids were
                               prepared from geological logging codes. Regolith units were prepared as digital surfaces below topography
                               based on the geological logging.
                             - The resulting models encompass the mineralisation, the post-mineralisation barren dykes, and the shears
                               controlling higher grade mineralisation and the main waste rock units that are the footwall and hanging wall to
                               the mineralisation.

 Dimensions                  -   The Open Pit Mineral Resource is reported within a combination of life-of-mine pit designs and an open pit
                                 Lerchs-Grossman-Analysis (LGA) pit optimisation ‘shell’ based on a gold price of 1,824 AUD/troy ounce
                                 (1,400 USD/troy ounce).
                             -   This reporting shell has dimensions of approximately 4.7km along strike, up to 1km wide and up to 450m
                                 deep, spanning all the major deposits.
                             -   The Underground Mineral Resource extends from the base of the Open Pit Resource below the Havana
                                 Open Pit with plan extents in long dimension down dip to the SE by up to 900 m and up to ?200 m wide.
                                 Additional Underground Mineral Resource is down-dip from the Boston Shaker Open Pit. A smaller lode
                                 extends from the Havana South pit with down dip extents of ? 200m and up to 200 m wide. Other parts of the
                                 Underground Resource are below the other pits.

Estimation and modelling   -   The Open Pit Mineral Resource:
techniques
                                o   Has been estimated from the drill hole data available to 16 January 2017, which included 3,666 drill
                                    holes for a total of 702,961 m of drilling of which, 1,101 holes were DD for 387,191 m and 2,421 holes
                                    were RC for 278,683 m. A further 144 holes of RC with DD holes totalled 37,087 of drilling.
                                o   The December 2017 update included 279 new holes (170 RC and 109 DD) for an additional 54,753 of
                                    drilling compared to the prior estimate.
                                o   The drill hole data was composited to 2m lengths within geological estimation domains using Vulcan
                                    software.
                                o   No grade top-cut or caps were applied to the composites, but high-grade estimation limits were applied
                                    to limit the spatial spread of high grades.
                                o   The composite data was declustered in each estimation domain using cell declustering commensurate
                                    with the drill spacing (25mE×25mN or 50mE×50mN and planned kriging panel height (10 m for Havana
                                    and Tropicana, 7.5 m for Boston Shaker)
                                o   Gold continuity was interpreted for each estimation domain and grades for large panels were estimated
                                    using ordinary block kriging in Isatis, with estimation panel dimension 30mE×45mN×10mElv used for
                                    Havana and Tropicana, and panels of 15mE×30mN×7.5mElv for Boston Shaker.
                                o   Sample searches were oriented down dip with a 160mX×160mY×30mZ search used for mineralised
                                    domains and 120mX×120mY×30mZ search in waste domains. A minimum of 8 (or 4 for Boston
                                    Shaker) and maximum of 32 samples were required for a panel grade to be estimated. A second pass
                                    search was then applied to address blocks with >1% negative kriging weights with the maximum
                                    number of samples reduced to 12.
                                o   Selective Mining Unit (SMU) grades were then estimated for each panel using the Local Uniform
                                    Conditioning method, where the SMU grade distribution within each panel is estimated through a
                                    change of support then the SMUs are localised using kriging so the distribution within the panel reflects
                                    the local grade trends in nearby data. The information effect of 12mE×12mN grade control information
                                    was accommodated in the change of support from panels to SMUs
                                o   The SMU dimensions were set to prepare 36 SMUs per panel with SMU dimensions of
                                    10mE×15mN×3.33mElv for Havana and Tropicana and 5mE×7.5mN×2.5mElv for Boston Shaker. The
                                    elevation heights nominally match the mining flitch heights applied at each area.
                                o   The estimate model was validated by comparing (input) data declustered means for each domain to the
                                    respective (output) block estimated grades both globally within each domain and locally using moving
                                    window ‘swath-plot’. On screen visual inspections were also completed in plan and section to ensure
                                    that the grade trends observed in the data were acceptably reproduced in the estimates without over
                                    extrapolation in areas of sparse drilling.
                                o   Comparison of the Open Pit estimate forecasts to mine production indicates acceptable forecasting
                                    performance for monthly, quarterly and annual recompilation periods.
                           -   The Underground Mineral Resource:
                                o   Is estimated in a separate model from the Open Pit with the model oriented to follow the 30? east dip of
                                    mineralisation.
                                o   The estimate has been prepared using Ordinary Block Kriging in Isatis software into block dimensions
                                    10mX×10mY×2mZ in the rotated coordinates.
                                o   A higher-grade zone (>2g/t) was defined by implicit modelling, with grades estimated into the higher and
                                    lower grades zones separately. Search ranges were consistent with the Open Pit estimate, with an
                                    additional longer–range search used.
                                o   Drill hole data were composited to 2m prior to estimation with no-top cuts applied
                                o   The model was validated in an equivalent manner to the Open Pit estimates.
                                o   There has been no mining of the Underground Resource to compare to the estimate
                           -   There are no assumptions relating to deleterious elements of non-grade variables of economic significance.
                               Gold and density are the only relevant variables.

                                    pits (‘Long Island Study’).
                                o   On the basis described above, and assuming lower processing costs and higher metallurgical oxide ore,

                                o   The Underground estimate cut-off grade is based on assumptions of a pre-feasibility study completed in
                                    2013 which used a gold price of 1,400 USD/tr.oz (1,817 AUD/tr.oz) and underground mining and
                                    process cost assumptions for fresh Mineral Resource.
                                o   The cut-off grade for reporting the Underground Mineral Resource on this basis is ?2.0g/t Au.

                           -   The assumption for the Underground Mineral Resource is long-hole open stoping between 20 m levels.
                           -   No Mineral Resource margin (external) dilution has been modelled in either estimate.
                           -   Eventual prospects of economic extraction for the Open Pit resource have been assessed through pit
                               optimisation studies and reporting the Mineral Resource within pit designs and an optimisation shell.
                           -   Eventual prospects of economic extraction for the Underground Resource have been demonstrated in the 2013
                               study, albeit the project development is not currently economical attractive at current metal prices and costs.

assumptions                   and legislative requirements.
                           - Mined waste rock is disposed in waste dumps which are progressively rehabilitated as mining progresses with
                              any potentially acid generating waste encapsulated in non-acid generating material.
                            - A tailing storage facility is used to contain and capture process residues.
                            - The mine produces rehabilitation plans for ongoing rehabilitation and mine closure plans, and the costs are
                              included in the financial model.


Bulk density               -  AngloGold routinely collects in situ bulk density measurements on ?10cm long core segments using the
                              Archimedes principle method of dry weight versus weight in water. There are ?138,000 density measurements
                              in the estimation database with 131,000 from fresh rock and the remainder in the regolith or cover.
                           - Measurements are collected over 1m to 5 m intervals targeting intervals that are deemed representative of key
                              lithology in fresh rock. Density has been collected on core within the regolith from ‘core-from-surface’ drill holes,
                              with the measurement method accounting for voids.
                            - Depending on rock type density ranges of 1.89 t/m3 to 2.18 t/m3 in the saprolite and ranges from 2.56 t/m 3 to

                            - Density is estimated by ordinary block kriging in the Mineral Resource estimates apart from a few minor
                               domains with sparse data (such as the regolith), where density is assigned as a mean of the data.

Classification             -   The basis of classification of the Tropicana estimates into different JORC Code confidence categories is drill
                               hole spacing as follows:
                                 o   Measured Mineral Resources: average 25mE×25mN collar spacing.
                                 o   Indicated Mineral Resources: average50mE×50mN collar spacing.
                                 o   Inferred Mineral Resources: average 100mE×100mN collar spacing (or less) when evidence of
                                     geological or grade continuity is sufficient to support grade estimation.
                           -   AngloGold considers that the Measured Resource supports mine planning with a 90% confidence interval of
                               ±15% on tonnage or grade on a quarterly production basis, with Indicated Resources have the same confidence
                               but applicable on an annual production basis.
                           -   The Competent Person considers this classification takes in to account all relevant factors such as data
                               reliability, confidence in the continuity of geology and grades, and the quality, quantity and distribution of the
                               data.
                           -   The classification reflects the view of the Competent Person reporting the estimate with the same methodology
                               applied to both the Open Pit and Underground estimates.

                           historical exchange rates.

Market assessment        - No specific market assessment has been completed for this Ore Reserve update.

Economic                 - The inputs into the economic analysis for the Ore Reserve update have already been described
                            above under previous subsections.
                         - The economic evaluation has been carried out on a real basis (adjusted for inflation) with rates
                            provided by AngloGold corporate.
                         - The confidence in majority of the economic inputs is high as Tropicana is an operating mine and as
                            such, costs (opex and capex) are well understood.
                         - The confidence in metal prices and exchange rates is consistent with routine industry practices with
                            the data derived from reputable forecasters.
                          - The discount rate used for NPV calculations is derived from the weighted average cost of capital in
                            Australia.
                          - Sensitivity studies have been completed on inputs such a mining and processing costs, gold price
                            and discount rate. NPV has the greatest sensitivity to gold price with an estimated 30,000 ounces
                            lost from the Ore Reserve for a 10% reduction in gold price.

Social                   - Tropicana Gold Mine has all necessary agreements in place with key stakeholders and matters
                           leading to social licence to operate.

Other                    - There are no material naturally occurring risks associated with the Tropicana operation.
                         - There are no material legal agreements or marketing arrangements not already discussed in prior
                           sub sections.
                         - All necessary government and statutory approvals are in place.
                         - There are no unresolved third-party matters hindering the extraction of the Ore Reserve.

Classification           - The Ore Reserve has been classified into Proved and Probable Ore Reserve JORC Code classes
                           based on the underlying MRE classification in the MRE model, with Measured Mineral Resources
                           converted to Proven Ore Reserves, and Indicated Mineral Resources converted to Probable Ore
                           Reserves.
                         - The classifications applied to the estimate are consistent with the opinion of the Competent Person
                           reporting the Ore Reserve.
                         - There is no portion of Probable Ore Reserves derived from Measured Mineral Resources

Audits or reviews        - A Mineral Resource and Ore Reserve audit was completed in 2017 and no material recommendation
                           came from the audit
                         - The current Ore Reserve estimate has been reviewed internally by AngloGold personnel

Discussion of relative   - AngloGold has carried out simulation to quantify the confidence in the Ore reserve – refer to the
accuracy/ confidence       commentary at the end of Section 3 above.
                         - The main driver of accuracy and confidence is the spacing of the pre-production drilling, which is
                           captured in the Mineral Resource JORC Code classifications underpinning the Ore Reserve
                           estimates.
                         - Confidence in Ore Reserve inputs is generally high given the mine is operation and costs, prices,
                           recoveries and so on are well understood.

       Criteria                                                  Commentary
                       - The Ore Reserve estimates are considerate to have sufficient local accuracy to support mine
                         planning and production schedules with Proved Ore Reserves considered a reliable basis for
                         quarterly production targeting and Probable Ore Reserves reliable for annual production targets.
                       - Confidence in the mine design and schedule are high as mining rates and modifying factors are
                         based on actual site performance. Mine designs are consistent with what has been effective
                         previously.
                       - The mine to mill reconciliation data to date indicates the forecast precision of the estimates is good
                         with the Ore Reserve estimate slightly conservative.
