UPDATED LIFE OF MINE PLAN FOR PERSEUS MINING’S EDIKAN GOLD MINE

Perseus Mining Limited (“Perseus”) (ASX/TSX: PRU) is pleased to announce details of its updated Life of Mine Plan (“LOMP”) for the Edikan Gold Mine (“EGM”) in Ghana, West Africa.

HIGHLIGHTS

  • Independently estimated Proved and Probable Ore Reserves for the EGM total 61.6 Mt of ore grading 1.2 g/t of gold and containing approximately 2.35 Mozs of gold as at 1 February 2015.

  • The revised LOMP involves mining and processing of ore from seven optimised open pits designed using US$1,200/oz pit shells and input costs based on actual operating experience and recently contracted supply agreements.

  • For the period from FY2016 to FY2023 inclusive, average gold production of 240,000 ounces/year at an average all-in site cash[1] cost of US$937/ounce.

  • Current FY2015 production and cost guidance of 200-210kozs of gold at an all-in site cash cost of US$1,075-1,125/ounce remains unchanged by the updated LOMP.

  • Value of future cash flows contribute materially to the underlying value of Perseus as follows:

Comments from Perseus’s Managing Director, Jeff Quartermaine

The updated Life of Mine Plan clearly demonstrates that Edikan is an economically robust operation that has successfully come through an extended ramp up phase. Based on this updated plan, the future prospects of Edikan, and therefore Perseus, are both very positive.

Over the past twelve months we have demonstrated that by focussing on achieving incremental improvements to both the technical and commercial aspects of our operation, we can consistently deliver credible results.

The external environment in which we operate can be unpredictable and challenging at times, however, based on recent performance, we are very confident that we have a highly professional site team that is adaptable and more than capable of rising to these challenges when they occur.

We are very much looking forward to consistently delivering to this plan and in the process creating material value for our shareholders.

MINERAL RESOURCES

An updated Mineral Resource estimate for EGM has been prepared by independent consultant, RungePincockMinarco (“RPM”) in accordance with the JORC Code – 2012 Edition. This estimate is based on the 1 May 2014 Mineral Resource estimate previously prepared by RPM that has been amended for mining depletion to 31 January 2015 in the case of the AF Gap and Fobinso pits. It has also been amended to include in-fill drilling results returned from a recent drilling campaign on the Mampong mineral deposit which amendment is immaterial to the total Edikan Resource.

In summary, the updated global Measured and Indicated Mineral Resource for EGM is now estimated as 149.5Mt grading 1.1g/t gold, containing 5.25 Mozs of gold. A further 68.1Mt of material grading 1.0g/t gold and containing a further 2.17 Mozs of gold are classified as Inferred Mineral Resources. Details of these estimates are shown below in Table 1.

SCENARIO PLANNING

Based on the revised Mineral Resource estimate, Perseus examined a range of development scenarios with the objective of maximising the net present value of forecast cash flows from EGM. This task involved varying key parameters such as the pit development sequence, applying technical assumptions that reflected actual operating parameters, and working within known constraints such as the expected timing of access to new mining areas. .

ORE RESERVES

Based on the re-estimated EGM Mineral Resource, pit optimisation and scheduling, RPM independently calculated the Ore Reserves for the EGM as at 1 February 2015 in accordance with the requirements of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code, 2012 Edition). (Refer to Appendix 1 for JORC 2012 Table 1)

In summary, the updated Proved and Probable Ore Reserve for EGM is now estimated as 61.6Mt grading 1.2g/t gold, containing 2.35 Mozs of gold including 44.2Mt of material grading 1.2g/t gold and containing a further 1.66 Mozs of gold in the Proved category and 17.3Mt of material grading 1.2g/t gold and containing a further 0.69Mozs of gold classified as Probable Ore Reserves. Details of these estimates are shown below in Table 2 .

The estimation of the Ore Reserves for Edikan was based on the following assumptions:

  1. Proven and Probable Ore Reserves are found within the economic limits of seven discrete open pits that have been designed based on Measured and Indicated Mineral Resources that incorporated all available Resource infill drilling results, a gold price of US$1,200/oz and mining, processing and general and administration costs derived from recent operating experience;

  2. The January 2015 Mineral Resource model has been re-blocked to reflect mining ore loss and dilution that is consistent with the historical reconciliations between the Resource model and grade control drilling (98% of contained gold) and between grade control drilling and the mill reconciliations (96% of contained gold);

  3. Economic assumptions

  4. a. Gold metal price US$1,200/oz.

  5. b. Un-escalated average costs used in optimising pit designs are as shown in Table 3 below.

  6. c. A discount rate of 10% (real) has been assumed to calculate net present values of forecast cash flows.

Notes:

  1. Estimate has been rounded to reflect accuracy

  2. All the estimates are on a dry tonne basis

  3. Based on March 2015 Mineral Resource estimation

  4. Variable gold cut-off grade based on material type

  5. Inferred Mineral Resource is treated as mineralised waste

  6. Calculated in March 2015 and allows for mining depletion up to and including 31 January 2015

  7. The boundary between Ore Reserves included in the Fetish and Bokitsi pits has been modified since calculation of the July 2014 Ore Reserve. The northern portion of the mineralised material that was previously to be mined in the Bokitsi pit will now mined in the Fetish Pit.

US$3.33/t mined US$9.03/t milled US$2.48/t milled US$0.04/oz sold 6.75%

4. Mining parameters

  • a. The chosen method of mining is conventional open pit mining utilising hydraulic excavators and trucks, mining bench heights of 5 m with 2.5m flitches to minimise ore loss and waste rock dilution.

  • b. The economic pit shell was defined using Whittle 4X pit optimisation software (“Whittle 4X”) with inputs such as geotechnical parameters, ore loss and dilution, metallurgical recovery and mining costs.

  • c. The pit optimisation was run with revenue generated only by Measured and Indicated Mineral Resources. No value was allocated to Inferred Mineral Resources.

  • d. Whittle 4X input parameters were generally based on Perseus’s operating site experience and supporting technical studies.

  • e. The pit slope design assumptions are based on a geotechnical study by George, Orr and Associates (Australia) Pty Ltd. Overall pit slopes are 30 to 50 degrees inclusive of berms spaced at between 5 and 20m vertically and berm widths of 5 to 12 m.

  • f. Pit ramps have been designed for a 777 truck fleet and are set at a net 16m (single lane) to 26m (dual lane).

  • g. Vertical mining advance has been set at a maximum of 90m/year based on historical performance and operational improvements.

==> picture [120 x 37] intentionally omitted <==

  • h. Appropriate mining modifying factors such as ore loss, dilution and design parameters were used to convert the Mineral Resource to an Ore Reserve.

  • i. Mining dilution varies by deposit as a result of block regularisation resulting in a range, due to multiple block models used, between 3-12%.

  • j. Minimum mining width of 40 m was generally applied to the pit designs.

  • k. As the mine has been in operation and the mining method is not changed, no major infrastructure is required due to the selected mining method other than that required to provide access to the Eastern and Northern mining areas.

  • l. There are no physical constraints to mining within the lease area. No property, infrastructure or environmental issues are known to exist which may limit the extent of mining within the mining lease.

  • m. Ore cut-off grades are based on the gold price, cost and mining parameters described in paragraphs 3, and 4(a) to (l) above and are as shown in Table 4 as follows:

  • n. Due to a reduction in contract mining costs, the push back of the AG Final pit wall will now extend to surface at the Stage 3 end of the AG pit and will take out most of the area of wall instability that has occurred on the southern side of the AG Stage 3 Pit.

  • o. Mining is scheduled to commence in the Eastern pits (including Fetish, Bokitsi and Chirawewa) in April 2015. As at the date of this release, the Ghanaian Environmental Protection Agency had not approved the Supplementary Environmental Impact Statement, a pre-requisite for the commencement of mining activities.

  • Processing parameters

  • a. The process metallurgical recovery for gold is fixed by material type in each deposit. Gold recovery rates range from 57-61% for oxide ore and 82-94% for primary ore. Recovery variation is a function of differing metallurgical properties of ores from different deposits and recoveries by pit are as shown in Table 5 .

  • b. No deleterious material has been identified.

  • c. Average annual processing throughput rate of ore from all pits of 7.0Mtpa. The processing circuit involves single stage crushing, semi-autogenous grinding, gravity recovery, flotation, regrind and CIL.

6

==> picture [120 x 37] intentionally omitted <==

  • d. A secondary crusher is planned to be installed and available for use by March 2016, at a capital cost of US$15 million.

  • e. Allowance has been made in the calculation of ore processing rates for the 33% decrease in plant availability in the months of February to April 2015 as a result of government imposed power restrictions. Beyond April 2015, an amount of power will be generated on site using diesel generators and this will supplement power from the grid and restore the availability of full power to the site.

6. Classification

Ore Reserves have been classified based on the underlying Mineral Resources classifications and the level of detail in the mine planning. The Mineral Resources were classified as Measured, Indicated and Inferred. The Ore Reserves, based only on the Measured and Indicated Resources, have been classified as Proven and Probable Ore Reserves, respectively.

The Ore Reserve is classified as Proved and Probable in accordance with the JORC Code, corresponding to the Mineral Resource classifications of Measured and Indicated and taking into account other factors where relevant. The deposit’s geological model is well constrained. The Ore Reserve classification is considered appropriate given the nature of the deposit, the moderate grade variability, drilling density, structural complexity and mining history. Therefore it was deemed appropriate to use Measured Mineral Resources as a basis for Proven Reserves and Indicated Mineral Resources as a basis for Probable Reserves.

No Inferred Mineral Resources were included in the Ore Reserve estimate.

UPDATED LIFE OF MINE PLAN

Based on the Ore Reserves stated above, the updated life of mine production profile for the EGM is forecast as shown in Table 6 below. In summary, in the eight years of production between FY2016 and FY2023 inclusive, annual gold production will average approximately 235,000ozs at weighted average all-in site cost of US$937/oz.

Compared to the October 2013 LOMP (adjusted for mining depletion to 31 January 2015), the updated LOMP results in the following changes to physical parameters:

  • Tonnes of ore and waste moved - Up by 4%

  • • Tonnes of Ore - Down by 18% • Life of mine strip ratio - Up by 1.3 to 4.0 • Head grade - Up by 8% • Contained gold in Ore Reserve - Down by 10% • Life of mine - Reduced by 14 months to July 2023

7

==> picture [120 x 37] intentionally omitted <==

The forecast unit all-in site cash costs for the EGM’s LOMP are also as shown in Table 6 below. It should be noted that these costs differ marginally from the input costs used in the calculation of the Ore Reserve and reflect actual cost reductions achieved plus cost reductions expected to be realised from recently implemented initiatives at the EGM in the period between the commencement of calculation of Ore Reserves and finalisation of pit optimisations. These estimated unit costs are based on the following assumptions:

  1. The weighted average un-escalated life of mine mining cost assumed in the LOMP is US$3.33/t of material moved. Mining costs include the cash cost of mining both ore and waste (including all waste stripping costs) during the period. The weighted average mining cost is based on the following:

  2. a. AG Pit – For Stages 2 and 3 of the pit, costs are contracted rates negotiated in November 2009 with mining contractor, African Mining Services (Ghana) Pty Ltd (“AMS”), adjusted for historical rise and fall factors. The costs for mining the Final Stage of the AG Pit are based on recently negotiated rates for mining the Final Stage of the Fobinso Pit.

  3. b. Fobinso Pit – un-escalated contracted rates negotiated in September 2014 with mining contractor Rocksure International.

  4. c. Fetish, Bokitsi, and Chirawewa (the “Eastern Pits”) - un-escalated contracted rates for mining the negotiated in March 2015 with mining contractor, AMS.

  5. d. Esuajah North and Esuajah South - mining rates are based on recently negotiated rates for minng the Eastern Pits.

  6. Un-escalated unit processing costs are assumed to be US$9.03/t of ore processed plus a further US$0.04/t of ore processed for bullion transport and refining costs.

  7. An un-escalated General and Administration unit cost of US$2.48/t of ore processed has been assumed for the remaining years of the mine.

  8. Royalty is based on a US$1,200/oz gold price and assumes a 5% royalty paid to the Ghanaian government, a 1.5% royalty payable to Franco Nevada and a 0.25% royalty payable to Waratah Investments Ltd.

  9. Sustaining capital expenditure is estimated at US$108 million (un-escalated) over the remaining life of mine. (Refer to Table 6 below for details).

The largest items of forecast capital expenditure relate to the total costs of gaining access to areas for mining within the existing Mining Lease boundary. Under Ghanaian laws, Perseus is required to compensate landowners for loss of crops, structures and livelihood as well as provide alternative housing built to the rigorous building standards specified in relevant legislation. In addition, where infrastructure such as roads is located within a blast radius of 500 metres from a planned open pit, the infrastructure needs to be relocated. In the case of the Esuajah South pit, this involves the relocation of several roads as well as a number of dwellings. In total, access costs accounts for approximately 64 percent of the total estimated sustaining capital required to be spent during the remaining 8-9 years of mine life.

The use of underground mining techniques to mine the Esuajah South Mineral Resource (and therefore minimise disruption to existing land use and the need for housing and infrastructure relocation) has been investigated, however, this is not an economic proposition at the currently assumed gold price. Notwithstanding the relatively high estimated cost of gaining access to the Esuajah South mine area, the economics of developing an open pit mining operation and processing the ore are incrementally positive, and therefore development of this pit has been included in the LOMP schedule. Further investigation of underground mining options is being considered.

Section 1 Sampling Techniques and Data

Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling (eg cut channels,
random chips, or specific specialised industry
standard measurement tools appropriate to the
minerals under investigation, such as down hole
gamma sondes, or handheld XRF instruments, etc).
These examples should not be taken as limiting the
broad meaning of sampling.

Include reference to measures taken to ensure
sample
representivity
and
the
appropriate
calibration of any measurement tools or systems
used.

Aspects of the determination of mineralisation that
are Material to the Public Report. In cases where
‘industry standard’ work has been done this would
be relatively simple (eg ‘reverse circulation drilling
was used to obtain 1 m samples from which 3 kg
was pulverised to produce a 30 g charge for fire
assay’). In other cases more explanation may be
required, such as where there is coarse gold that
has
inherent
sampling
problems.
Unusual
commodities or mineralisation types (eg submarine
nodules) may warrant disclosure of detailed
information.
AAF

Drill holes included in the Mineral Resource
were sampled using close spaced Grade Control
(GC) drilling on a nominal 8m to 10m grid, and
Reverse Circulation (RC), and diamond drill (DD)
holes on a nominal 20m by 40m grid spacing. A
total of 4,890 holes were included in the
resource for a total 134,341m within the
resource wireframes. Holes were generally
angled at 60° towards grid south to optimally
intersect the mineralised zones. Grade control
holes were drilled vertically.

Drill hole collars were picked up and down hole
surveyed by licensed surveyors. RC samples
were collected by a riffle splitter at 1m intervals.
Diamond core was cut in half using a core saw
with sampling at 1m intervals, locally to
geological
boundaries.
All
samples
were
collected from the same side of the core.
Sampling and QAQC procedures were carried
out to industry standards.

Approximately 6% of all RC samples were sent to
ALS Minerals at Kumasi/Ghana for 24hr bottle
roll with AAS finish. All other RC samples were
analysed by 50g Fire Assay and AAS finish.
Diamond half core samples were sent to Intertek
Laboratories (Gh) Ltd at Tarkwa/Ghana for 50g
Fire Assay and AAS finish.
Fetish

Samples at Fetish were collected using drilling
techniques such as Reverse Circulation (RC) and
Diamond Drilling (DD). Holes were generally
angled at between 45° and 60° towards grid
west or east to optimally intersect the
mineralised zones. Some RC drill holes have
diamond tails.

RC samples were collected as 4m composites
until potential mineralisation was expected at
which time samples were collected at 1m
intervals from a rig mounted cyclone into large
numbered plastic bags. Recently, PRU drilling
has used 2m composite samples, and then 1m
samples
through
potential
mineralisation.

HQ2 and NQ2 sized equipment.
Drill
sample
recovery

Method of recording and assessing core and chip
sample recoveries and results assessed.

Measures taken to maximise sample recovery and
ensure representative nature of the samples.

Whether a relationship exists between sample
recovery and grade and whether sample bias may
have occurred due to preferential loss/gain of
fine/coarse material.

Recoveries from historical drilling are unknown.
Actual recoveries from PRU diamond drilling
recorded in the database and averaged as
follows for each deposit with no significant
issues noted:

geologically and geotechnically logged to a level of
detail to support appropriate Mineral Resource
estimation, mining studies and metallurgical
studies.

Whether logging is qualitative or quantitative in
nature.
Core

The total length and percentage of the relevant
intersections logged.

All holes were field logged by company
geologists. Weathering, lithology, alteration,
structure, mineralogy and veining information
were recorded. RC chips are glued to boards as
a visual reference of every hole.

Logging of diamond core additionally recorded
recovery, core strength, orientation, roughness,
and infill type. Diamond core was photographed.

For all sample types, the nature, quality and
appropriateness
of
the
sample
preparation
technique.

Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.

Measures taken to ensure that the sampling is
representative of the in situ material collected,
including
for
instance
results
for
field
duplicate/second-half sampling.

Whether sample sizes are appropriate to the grain
size of the material being sampled.
Esuajah North samples were predominantly dry.
Esuajah South samples were predominantly wet
but very few occur within the Mineral Resource
wireframes. For AAF 1% of samples were
recorded as wet in the supplied database in the
‘sampquality’ field and were removed from the
resource composites. For Esuajah North less than
0.5% of samples were recorded as ‘wet’ in the
supplied data in the ‘sampquality’ field, although
55% of records in this field are blank.

Sampling of diamond core and RC chips uses
industry standard techniques. After drying the
sample is subject to a primary crush, then
pulverised so that 90% passes a -75um sieve.

Field QC procedures involved the use of certified
reference materials (1 in 20), and field duplicates
(1 in 20).

Field duplicates were taken on 1m to 2m
composites for RC using a riffle splitter.

Sample sizes are considered appropriate to
correctly represent the moderately nuggetty gold
mineralisation
based
on:
the
style
of
mineralisation, the thickness and consistency of
the intersections, the sampling methodology and
assay value ranges for Au.
Quality of assay
data
and
laboratory tests

The nature, quality and appropriateness of the
assaying and laboratory procedures used and
whether the technique is considered partial or
total.

For geophysical tools, spectrometers, handheld
XRF instruments, etc, the parameters used in
determining the analysis including instrument
make and model, reading times, calibrations
factors applied and their derivation, etc.

Nature of quality control procedures adopted (eg
standards, blanks, duplicates, external laboratory
checks) and whether acceptable levels of accuracy
(ie lack of bias) and precision have been
established.

The analytical techniques used Fire Assay on 50g
samples or BLEG bottle roll on 1kg samples both
with AAS finish. This method approaches total
dissolution of most minerals.

No geophysical tools were used to determine any
element concentrations used in the resource
estimate.

Sample preparation checks for fineness were
carried out by the laboratory as part of internal
procedures to ensure the grind size of 90%
passing 75µm was being attained. Laboratory
QAQC includes the use of internal standards using
certified reference material, and pulp replicates.
Certified reference materials demonstrate that
sample assay values are accurate.

The QAQC results confirm the suitability of the
drilling data for use in the Mineral Resource
estimation.
Verification
of
sampling
and
assaying

The verification of significant intersections by
either
independent
or
alternative
company
personnel.

The PRU logging process involves placing RC drill
samples for each 1m interval onto a board to
form a visual log of the entire hole. PRU senior
exploration personnel verified the significant
intersections by comparing the returned assay
results to the photographs of the ‘chip boards’.

RPM has not independently verified significant
intersections of mineralisation.

Discuss any adjustment to assay data.

For AAF a total of 4 RC holes have been twinned
by DD to test down hole contamination in wet
intervals.
Twinned holes have not been drilled for Fetish,
Bokitsi and Chirawewa. The same applies to Esuajah
South althouth the east and west dipping holes on
20m spacing result in ‘crossing’ of drill traces at
depth.
For Esuajah North DKRC067 and DKRC068 are
twinned holes and display similar down hole grades.
The east and west dipping holes on 40m spacing
result in ‘crossing’ of drill traces at depth.

Primary data is entered on hard copies in the
field,
then
entered
digitally
using
LogChiefSoftware (Maxwell GeoServices). This
data is directly imported into the central
Datashed database (Maxwell GeoServices).

Assay values that were below detection limit
were adjusted to equal half of the detection
limit value. Intervals with no samples were left
blank in the database (updated from the -9 value
used by PRU).
Location of data
points

Accuracy and quality of surveys used to locate drill
holes (collar and down-hole surveys), trenches,
mine workings and other locations used in Mineral
Resource estimation.

Specification of the grid system used.

Prior to 2012, a local grid, including baseline,
was established at Edikan by Cluff Plc using
licensed surveyors. Licensed surveyors were
used to locate all drill collars in local grid co-
ordinates.

The majority of PRU drill holes are surveyed
down hole at 10m to 30m intervals using either
Reflex or Flexit multi-shot equipment. Historical
RC holes have not been down hole surveyed and
are assumed to be straight. Historical diamond
holes were down hole surveyed using either acid
tubes or a single shot camera.

For recent drill programs, collars have been
located in UTM, WGS84, Zone 30N co-ordinates
and transformed to local grid. True azimuths
were converted to local by subtracting 43 from
the true value.

Local RL elevations were adjusted by adding
1,000m to avoid negative values. This was not
done for the previous Mineral Resource
estimates.

weighting
averaging techniques, maximum and/or minimum
grade truncations (e.g. cutting of high grades) and
cut-off grades are usually Material and should be
stated.
Where aggregate intercepts incorporate short
lengths of high grade results and longer lengths of
low grade results, the procedure used for such
aggregation should be stated and some typical
examples of such aggregations should be shown in
detail.

The assumptions used for any reporting of metal
equivalent values should be clearly stated.

Exploration drill results have been previously
reported by PRU.

No aggregation of intercepts was carried out.
Drilling intervals are predominantly even 1m, or
composites of 2m or 4m. Mineralised composites
are re-split to 1m for re-assay.

Metal equivalent values are not being reported.
Relationship
between
mineralisation
widths
and
intercept
lengths
These relationships are particularly important in the
reporting of Exploration Results.

If the geometry of the mineralisation with respect
to the drill hole angle is known, its nature should
be reported.
If it is not known and only the down hole lengths
are reported, there should be a clear statement to
this effect (e.g.’down hole length, true width not
known’).

Drill holes are angled to local grid which is
approximately perpendicular to the orientation of
the mineralised trend.
Diagrams Appropriate maps and sections (with scales) and
tabulations of intercepts should be included for any
significant discovery being reported. These should
include, but not be limited to a plan view of drill
hole collar locations and appropriate sectional
views.

A plan showing drilling on the deposits is
included in the underlying Mineral Resource
reports.
Balanced
Reporting

Accuracy and quality of surveys used to locate drill
holes (collar and down-hole surveys), trenches,
mine workings and other locations used in Mineral
Resource estimation.
Where comprehensive reporting of all Exploration
Results is not practicable, representative reporting
of both low and high grades and/or widths should
be practiced to avoid misleading reporting of
Exploration Results.

Drill holes have been accurately located by PRU
surveyors using the local grid system.

Database
integrity

Measures taken to ensure that data has not been
corrupted by, for example, transcription or keying
errors, between its initial collection and its use for
Mineral Resource estimation purposes.

Data validation procedures used.

The data base is systematically audited by PRU
geologists. All drill logs are validated digitally by
the database geologist once assay results are
returned from the laboratory. In 2010, RUL
reviewed the logging of several holes and
validated the records in the database against the
drill core and logging boards. No significant
errors were noted.

RPM also performed data audits in Surpac.

For AAF RPM validated the 2013 data against
previous data from the 2011 estimate. The dip
and depth intervals of down hole surveys for a
number of drill holes differed from the 2011
database. PRU instructed RPM to use the 2011
data for those holes as the errors were
attributed to converting of the PRU current
database to Datashed format.
RPM noted that recent supplied grade control
information contained duplicate hole_id’s.
These have been documented and were sent to
PRU. All the affected hole numbers were
excluded from the current resource update.
For Esuajah North RPM validated the 2013 data
against previous data from the 2012 estimate.
For Esuajah South RPM validated the 2013 data
against previous data from the 2010 estimate.
One drill hole (AKRDD256) had an incorrect
prospect name so had not been used in
previous estimates. The dip and depth intervals
of down hole surveys for a number of drill holes
differed
from

Reconciliation with historic production records
was
conducted
by
RUL
in
2010.
The
discrepancies noted between the model and
reported production was attributed to the pit
having not been accurately surveyed, and
currently filled with water. The mined portion of
the model was based on the survey of the pit.

RPM has completed numerous Mineral Resource
estimates for the deposits since 2009. Each
successive update was based on the previous
estimate. For AAF mine reconciliation figures
show that reconciliation is +8% for the AAF
deposit to date.

No assumptions have been made regarding
recovery of by-products.

No estimation of deleterious elements was
carried out. Only Au was interpolated into the
block models.

An orientated ‘ellipsoid’ search was used to
select data and was based on parameters taken
from the variography or the observed lode
geometry at each deposit. Three passes were
used for each domain. The following search
parameters were used at each deposit

minimum of 10 samples. For the second pass,
the range was extended to 60m, with a
minimum of 6 samples. For the final pass, the

was used to control the resource estimates.

Discussion of basis for using or not using grade
cutting or capping.

The process of validation, the checking process
used, the comparison of model data to drill hole
data, and use of reconciliation data if available.

The deposit mineralisation was constrained by
wireframes constructed using a 0.2g/t Au cut-off
grade in association with logged lithology codes.
The wireframes were applied as hard boundaries
in the estimate.

Statistical analysis was carried out on data from
28 lodes for AAF, 30 lodes for Fetish, all lodes for
Bokitsi, 14 lodes for Chirawewa . The high
coefficient of variation and the scattering of high
grade values observed on the histogram for some
of the lodes suggested that high grade cuts were
required if linear grade interpolation was to be
carried out. As a result high grade cuts ranging
between 10g/t to 30g/t (10-50g/t for Bokitsi)
were applied to selected domains, resulting in a
total of 86 samples being cut for AAF, 23 for
Fetish, 20 for Bokitsi, 31 for Chirawewa.

A three step process was used to validate each
model. A qualitative assessment was completed
by slicing sections through the block model in
positions coincident with drilling. A quantitative
assessment of the estimate was completed by
comparing the average Au grades of the
composite file input against the Au block model
output for all the resource objects. A trend
analysis was completed by comparing the
interpolated blocks to the sample composite
data within the granite domain. This analysis was
completed for:

20m eastings and 10m bench heights for
AAF;

20m northings and 20 bench heights for
Fetish, Esuajah North and Esuajah South;

20m northings for Bokitsi;

The Chirawewa deposit is of similar style to that

underground mining.

RPM has assumed that the Esuajah South deposit
could potentially be mined using large scale open

scale open pit mining of the oxide material has
previously occurred at Esuajah South.
Metallurgical
factors
or
assumptions

The basis for assumptions or predictions regarding
metallurgical amenability. It is always necessary as
part of the process of determining reasonable
prospects for eventual economic extraction to
consider potential metallurgical methods, but the
assumptions regarding metallurgical treatment
processes and parameters made when reporting
Mineral Resources may not always be rigorous.
Where this is the case, this should be reported with
an explanation of the basis of the metallurgical
assumptions made.

Extensive metallurgical test-work was completed
on material from a number of deposits within
Edikan Project area, by AMMTEC Pty Ltd in Perth
for Cluff Plc in the early 1990’s. This focused on
CIL test-work on both oxide and sulphide
material and later to heap leach. Preliminary
amalgamation and cyanidation results using
bottle roll methodology confirmed the free
milling nature of both the oxide and granite
mineralisation.

Metallurgical test-work was undertaken by PRU
in 2011 as part of the DFS.

Mineralisation characteristics of the granite
hosted mineralisation at Fetish are similar to the
mineralisation being processed at the AAF
operation.

Mineralisation characteristics of the sediment
hosted mineralisation at Bokitsi are different to
the mineralisation currently being processed at
the Edikan operation. Metallurgical response is
not as favourable as AAF but testwork has shown
that gold recovery from Bokitsi is still adequate.
Environmental
factors
or
assumptions

Assumptions made regarding possible waste and
process residue disposal options. It is always
necessary as part of the process of determining
reasonable prospects for eventual economic
extraction to consider the potential environmental
impacts of the mining and processing operation.
While at this stage the determination of potential
environmental
impacts,
particularly
for
a
greenfields project, may not always be well
advanced, the status of early consideration of
these potential environmental impacts should be
reported. Where these aspects have not been
considered this should be reported with an

made.

diamond core samples of which 360 were
conducted in-house by PRU and 378 completed
by commercial laboratories.

A recent study by PRU (2014) determined that
the current density assigned to fresh granite was
likely too high. This assumption was based on a
better understanding of the granite lodes from
open pit mining activities which suggested the
material should be less dense than originally
expected. A program of submitting existing drill
core for analysis was instigated in early 2014. A
total of 254 grab samples from the AAF pit and
485 drill core samples were sent to commercial
laboratories for analysis.. Results suggested the
fresh granite material had a density in the order
of 2.7t/m3 and that fresh sediment material had
a density of 2.77t/m3. These values have been
assigned to this material type in the current RPM
block models.

Measurements were determined by wax coating
samples and immersing in water.

RPM recommends an ongoing program of
submitting grab samples to laboratories for
analysis. Suitable core samples from any future
diamond drilling programs should be selectively
sent for analysis.

Mineral Resources were classified in accordance
with the Australasian Code for the Reporting of
Exploration Results, Mineral Resources and Ore
Reserves (JORC, 2012). Classification at each
deposit was based primarily on data quality,
continuity of mineralization, drill spacing, and
confidence in the geological interpretation and
subsequent block model estimation.

north and south margins of the granite where
continuity of mineralisation was good. Areas of
the resource defined at greater than 40m
spacing, as well as the sediment to the south of
the main granite, were classified as Inferred
Mineral Resource. This includes the sparsely
intersected depth extension of the mineralised
granite.
Esuajah South

The
Mineral
Resource
was
classified
as
Measured, Indicated and Inferred Mineral
Resource based on data quality, drill hole
spacing, and continuity of mineralisation. The
portion of the granite where the drill spacing
was 20m by 20m or less and demonstrating good
lode and grade continuity supported by high
kriging efficiencies was classified as Measured
Mineral Resource. This was confined to the
central portion of the granite domain from
surface down to 830mRL. The portion of the
deposit where the drill spacing was generally
greater than 20m by 20m but still demonstrated
good lode and grade continuity was classified as
Indicated Mineral Resource. The portion of the
deposit classified as Inferred Mineral Resource
included areas where the drill spacing was
greater than 40m by 40m (generally the deeper
portions of the granite), and the zones of
mineralisation within the adjacent sediments
that were defined by limited drilling.

The input data is comprehensive in its coverage
of the mineralisation and does not favour or
misrepresent in-situ mineralization at each
deposit. The definition of mineralised zones is
based on high level geological understanding
producing robust models of mineralised
domains. The AAF model has been confirmed by
infill drilling and mining which supported the
interpretation. Validation of the block models
shows good correlation of the input data to the
estimated grades.

Mining factors or
assumptions

The method and assumptions
used as reported in the Pre-
Feasibility or Feasibility Study
to convert the Mineral Resource
to an Ore Reserve (i.e. either by
application of appropriate
factors by optimisation or by
preliminary or detailed design).

The choice, nature and
appropriateness of the selected
mining method(s) and other
mining parameters including
associated design issues such as
pre-strip, access, etc.

The assumptions made
regarding geotechnical
parameters (eg pit slopes, stope
sizes, etc), grade control and
pre-production drilling.

The mining recovery factors

The manner in which Inferred
Mineral Resources are utilised
in mining studies and the
sensitivity of the outcome to

The chosen method of mining is conventional open pit mining
utilising hydraulic excavators and trucks, mining bench heights of 5
m with 2.5m flitches to minimise ore loss and waste rock dilution.

The economic pit shell was defined using Whittle 4X pit
optimisation software (“Whittle 4X”) with inputs such as
geotechnical parameters, ore loss and dilution, metallurgical
recovery and mining costs.

The pit optimisation was run with revenue generated only by
Measured and Indicated Mineral Resources. No value was allocated
to Inferred Mineral Resources.

Whittle 4X input parameters were generally based on Perseus’s
operating site experience and supporting technical studies.

The pit slope design assumptions are based on a geotechnical study
by George, Orr and Associates. Overall pit slopes 30 to 50 degrees
inclusive of berms spaced at between 5 and 20m vertically and
berm widths of 5 to 12 m.

Appropriate mining modifying factors such as ore loss, dilution and
design parameters were used to convert the Mineral Resource to an
Ore Reserve

Mining dilution varies by deposit as result of block regularisation
resulting in a range, due to multiple block models used, between 3-
12%.

Minimum mining width of 40 m was generally applied to the pit
designs.

As the mine has been in operation and the mining method is not
changed, only infrastructure needed to access new mining areas is
required due to the selected mining method.

RPM has not identified or been informed of any physical constraints
to mining within the lease area. No property, infrastructure or
environmental issues are known to exist which may limit the extent
of mining within the mining lease.

should be reported.

No environmental issues are known to exist which will prevent open
pit mining and ore processing to continue to operate. Perseus
appears to have sufficient space available for waste dumps to store
the expected quantities of mine waste rock associated with the
Edikan open pit Ore Reserve. Based on testing to date there is no
risk of acid rock drainage as any potentially acid generating material
is encapsulated within acid neutralising material.

Edikan has sufficient capacity in its purpose designed and approved
tailings storage facilities to meet the requirements generated from
mining and processing quantities listed in for the Edikan Ore
Reserve. The FTSF has been designed to contain up to 54 million
tonnes of flotation tailings depending on the insitu density achieved
in the deposited tailings. The final crest height of the embankments
will be RL203m. The CTSF is double HDPE lined facility with
underdrainage above the top liner and a leak detection system
between the upper and lower liner. It has capacity for 1.5 Mm3 of
tailings which is sufficient for the life of mine.

Ore Reserves, respectively.

The Ore Reserve is classified as Proved and Probable in accordance
with the JORC Code, corresponding to the Mineral Resource
classifications of Measured and Indicated and taking into account
other factors where relevant. The deposit’s geological model is well
constrained. The Ore Reserve classification is considered
appropriate given the nature of the deposit, the moderate grade
variability, drilling density, structural complexity and mining history.
Therefore it was deemed appropriate to use Measured Mineral
Resources as a basis for Proven Reserves and Indicated Mineral
Resources as a basis for Probable Reserves.

No Inferred Mineral Resources were included in the Ore Reserve
estimate.
Audits or reviews
The results of any audits or

RPM has completed an internal review of the Ore Reserve estimate.

The JORC Code provides guidelines which set out minimum
standards, recommendations and guidelines for the Public
Reporting of exploration results, Mineral Resources and Ore
Reserves. Within the JORC Code is a “Checklist of Assessment and
Reporting Criteria” (Table 1 – JORC Code). This checklist has been
used as a systematic method to undertake a review of the
underlying Study used to report in accordance with the JORC Code.

A high level LOM Plan was prepared based on the ROM mineable
ore contained with the pit designs. RPM reviewed the LOM Plan for
reasonableness and accuracy and confirmed that it was suitable for
estimation of Ore Reserves. An economic model was prepared by
Perseus that confirmed the Operation to be economically viable.

quantify the relative accuracy
of the reserve within stated
confidence limits, or, if such an
approach is not deemed
appropriate, a qualitative
discussion of the factors which
could affect the relative
accuracy and confidence of the
estimate.

The statement should specify
whether it relates to global or
local estimates, and, if local,
state the relevant tonnages,
which should be relevant to
technical and economic
evaluation. Documentation

The accuracy and confidence of the inputs are, as a minimum, of a
feasibility level (for the global open pit Ore Reserves).

The key factors that are likely to affect the accuracy and confidence
in the Ore Reserves are:
o
Accuracy of the underlying Resource Block Models;
o
Changes in gold prices and sales agreements;
o
Changes in metallurgical recovery; and
o
Mining loss and dilution.

The Ore Reserve has utilised all parameters provided by site as
made available.

The accuracy of the underlying Mineral Resources is defined by the
Resource Category that the Mineral Resources are assigned to. Only
the highest categories of Resource classification, Measured and
Indicated, have been used as a basis for estimating Ore Reserves.
