DATA DEMONSTRATES HIGH-GRADE POTENTIAL AT BOUAFLÉ PROJECT IN CÔTE D’IVOIRE
Highlights
Significant high-grade intercepts, not previously released include:
23m at 2.5 g/t gold from 92m in hole BFRC069
9m at 4.3 g/t gold from 132m in hole BFRC060
12m at 5.6 g/t gold from 48m in hole BFAC627
16m at 2.3 g/t gold from 8m in hole BFAC980
8m at 9.4g/t gold from 4m in hole BFAC933
The complete data set includes 18,300 soil samples which outline anomalous gold in soil over a strike length of 17 kilometres.
Drilling data includes results from 994 aircore holes, 85 reverse circulation holes and nine diamond drill holes, for a total of over 80,000m of drilling.
High resolution airborne magnetic and radiometric data over 16,500 line kilometres to be used for direct drill targeting.
Several drill-ready targets exist based on follow up of high-grade intercepts that have never been fully drill tested.
Tanga Resources Limited (ASX: TRL) (Tanga or the Company) is pleased to announce the findings of a review of data on its Bouaflé Project located in Côte d’Ivoire. The review found a number of high-grade gold intercepts, which together with geochemical and geophysical data, have identified several drill-ready targets for follow up.
Tanga’s Chairman, Andrew Pardey, commented:
“We are extremely pleased to be able to release such a significant volume of data on our Bouaflé
Project in Côte d’Ivoire, including soil geochemistry, high resolution airborne geophysics and drilling
data. The tenement package remains highly prospective, with previous work having identified a 17-
kilometre long gold in soil anomaly, supported by numerous high-grade aircore and RC drill
intersections. Importantly for Tanga, many of these intersections were never adequately followed up
and this presents targets for further exploration and drilling with potential for high-grade discoveries.”
The data was acquired through multiple sources, including the former owner, Newcrest Mining Limited (Newcrest).

Project Work History at the Bouaflé Project
The Bouaflé Project was previously held by Newcrest subsidiary Equigold and explored by Newcrest
between 2009 and 2014. Equigold was acquired by Lihir Gold in 2008 and Lihir Gold was
subsequently acquired by Newcrest in 2010.
Work commenced on the Bouaflé Project in 2009 with the collection of 12,652 regional soil samples,
which were infilled with a further 10,812 samples, that together delineated the 17km long gold in soil
anomaly shown in Figure 1 below. The anomalous soil samples are particularly useful in delineating
the prospective structural corridor as outlined in the regional geology and geophysical datasets.

Following the successful soil sampling program conducted in 2009, Equigold undertook an airborne
magnetic and radiometric survey over the Bouaflé Project area in 2010 and then expanded this
program in 2012 to further cover the Bouaflé greenstone belt to the south of the project area. This
airborne survey was flown with a line spacing of 100m and a sensor height of 50m which produces a
very high definition magnetic image and allows for direct interpretation of the geology and the
structural features of interest without the need for further follow-up ground magnetics in most areas,
thereby providing significant cost and time savings.
Between 2011 and 2012, Equigold conducted an extensive large aircore drilling campaign consisting
of 994 holes for a total of 41,980 metres. Significant intercepts from this program included:
8m at 9.4g/t gold from 4m in hole BFAC933
12m at 5.6 g/t gold from 48m in hole BFAC627
16m at 2.3 g/t gold from 8m in hole BFAC980
23m at 1.1 g/t gold from 52m in hole BFAC940 ending in mineralisation and
12m at 2.1 g/t gold from 28m in hole BFAC222
Between 2012 and 2013 Equigold completed nine diamond drillholes and one RC drillhole with a
diamond tail for a total of 2,990m. Significant intercepts from this program included:
15.3m at 1.8 g/t gold from 197m in hole BFDD007
1.5m @ 16.2 ppm gold from 22m in hole BFDD009
3.64m at 4 g/t gold from 246.36m in hole BFDD006
Importantly, this drilling program and subsequent RC drilling delineated the Bouaflé North prospect,
which has recorded high-grade intersections over 1,000m of strike and represents an outstanding
drill-ready target.
Finally, between 2012 and 2013, Equigold executed a large RC drilling program consisting of 79 drill
holes for a total of 14,894m. This program was designed to better define mineralised segments of the
shear and recorded the following significant intercepts:
23m at 2.5 g/t gold from 92m in hole BFRC069
9m at 4.3 g/t gold from 132m in hole BFRC060
9m at 2.2 g/t gold from 31m in hole BFRC040
10m at 1.7 g/t gold from 21m in hole BFRC037
7m at 2.3 g/t gold from 33m in hole BFRC016
7m at 2.1 g/t gold from 155m in hole BFRC060

Bouaflé Project Geology
The Bouaflé Project is located on the Bouaflé greenstone belt which hosts the Yaouré deposit, owned
by Perseus Mining and currently under construction, and containing resources of 3.8Moz at 1.25g/t
Au including an underground resource of 346koz at 6.1g/t Au.1
The Bouaflé belt is divided into two domains; an eastern mafic domain and a western volcano-
sedimentary domain on which the Bouaflé Project Licences are situated.
Historically, the project was divided into three project areas, Bouaflé North, Central and South
targeting shear hosted mineralisation along a 17km mineralised trend as outlined by more than 900
aircore holes totalling some 40,000m of drilling completed by Newcrest between 2010 and 2012. This
drilling outlined a coherent geochemical anomaly with gold in soil of over 30ppb (See Figure 1).2
Follow-up drilling at the Bouaflé Project Licences defined two main mineralised areas referred to as
the Main Mineralised Shear Zone (MMSZ) and the East Mineralised Zone (EMZ). The MMSZ is a sub-
vertical shear zone hosted on the contact between the Dianfla granodiorite and the Birimian sediments
which mainly consist of sheared sandstone and siltstone. The EMZ includes mineralisation hosted on
the Okabo Shear Zone which is a parallel mineralised structure some 400m to the east of the MMSZ.
Drillholes indicate that the mineralisation in this zone consists of steeply west dipping gold bearing
quartz veins and sub-vertical pyritised sediments.
Other historical drilling, previously released by Newcrest included intercepts of:
8m at 18 g/t gold from 116m in hole BFRC0413
18m at 2.4 g/t gold from 107m in Hole BFRC0674
15m at 2.0 g/t gold from 136m in hole BFRC0612
10m at 1.2 g/t gold from 42m and 5m at 2.3 g/t from 55m in hole BFRC0754
32m at 1 g/t gold from 140m in hole BFRC0321
The Company believes that mineralisation remains open and untested both along strike and down dip
and that multiple drill-ready targets exist on the Bouaflé Project.

Appendix 1. JORC Table 1 Reporting
Section 1 Sampling Techniques and Data
CRITERIA 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.
Core assay samples were collected on half core sawed lengthwise with a
diamond saw. Sampling intervals were marked by an appropriately qualified
geologist depending on geology. Sampling intervals may vary between 0.3
and 5 metres in length with an average of 1 metre in mineralisation.
Aircore chips were spear sampled and combined into 4m composites. RC
chips were riffle split and combined into 4m composites.
Aspects of the determination of
mineralisation that are Material to
the Public Report.
Core samples are selected based on geological criteria (presence of quartz
veining and sulphide mineralisation). Sample lengths are between 0.3 and
1.2m in mineralisation and may be up to 5m in unmineralised material. Core
samples are crushed to -3mm, split and a 250g sub-sample is pulverised
with gold determined by fire assay/AAS based on a 30-50g charge.
Drilling
techniques
Drill type (eg core, reverse
circulation, open-hole hammer,
rotary air blast, auger, Bangka,
sonic, etc) and details (eg core
diameter, triple or standard tube,
depth of diamond tails, face-
sampling bit or other type, whether
core is oriented and if so, by what
method, etc).
Diamond drilling was conducted using either PQ (81mm) or HQ (63mm) in
weathered material and then reduced to NQ (40mm in diameter) in fresh
rock. Holes were drilled with a dip of between 45 and 90 degrees and
oriented roughly perpendicular to mineralisation. Core was oriented using a
Reflex ACT II core orientation tool. RC drilling was conducted with a 5.25
inch face sampling bit. Aircore was conducted using a 3.35 inch Aircore
blade bit.
Drill Sample
Recovery
Method of recording and
assessing core and chip sample
recoveries and results assessed.
Diamond drill hole recoveries were recorded during logging by measuring
the length of core recovered per 3m core run. Core recovery was calculated
as a percentage by measuring the recovery of actual core length divided by
expected core length. No recovery data for Aircore or RC drilling has been
sighted.
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.
Core recovery was routinely measured and monitored during drilling. There
is no known relationship between recovery and grade.
Logging
Whether core and chip samples
have been geologically and
geotechnically logged to a level of
detail to support appropriate
Mineral Resource estimation,
mining studies and metallurgical
studies.
All core and chip samples have been to a level of detail appropriate to
inclusion in a Mineral Resource estimation or future mining studies.
TORRENSMINING.COM PAGE 12 OF 16
CRITERIA EXPLANATION COMMENTARY
Whether logging is qualitative or
quantitative in nature. Core (or
costean, channel, etc)
photography.
Logging of drill core is qualitative and records colour, texture, lithology,
weathering, structure, alteration, veining and sulphides. No drill core
photography has been received for this project.
The total length and percentage of
the relevant intersections logged.
All drill holes have been logged in full.
Sub-
Sampling
techniques
and sample
preparation
If core, whether cut or sawn and
whether quarter, half or all core
taken.
Core samples were selected at intervals typically between 0.3-1.2m in
length. Core samples were cut in half using a rock saw, with half of the
sample retained in the core box and half inserted into a plastic sample bag.
If non-core, whether riffled, tube
sampled, rotary split, etc and
whether sampled wet or dry.
Aircore samples were spear sampled, RC samples were riffle split at the rig.
Non-core samples were combined into 4m composites.
For all sample types, the nature,
quality and appropriateness of the
sample preparation technique.
Sample preparation consisted of jaw crushing to -3mm, splitting 500 grams
and pulverizing to 95% passing 75µ. A sub-sample of 150-200g (pulp
sample) is retained for analysis.
The sample preparation procedures carried out are considered acceptable.
Quality control procedures
adopted for all sub-sampling
stages to maximise representivity
of samples.
Both Core and RC sample duplicates were submitted to monitor bias and
ensure representivity of sampling.
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.
Duplicates, Blanks and Standards (Certified Reference Material) were used
to ensure assay quality and representativeness of sampling.
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.
All samples were assayed for gold by fire-assay with AAS finish by Bureau
Veritas in Abidjan, Côte d’Ivoire. This is considered to be a total analysis for
Gold.
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.
Airborne magnetic and Radiometric data was collected using a Caesium
vapour total field magnetometer and a fluxgate 3 component vector
magnetometer mounted in a stinger array on the tail of the aircraft. Readings
were taken at 0.1 second intervals. Standard diurnal, aircraft magnetic field
and altitude calibrations have been applied to the data.
Radiometric data was collected using an Exploranium GR820 gamma ray
spectrometer with readings every second.
The survey was carried out by UTS Aeroquest under Job number B182 in
2010.

CRITERIA EXPLANATION COMMENTARY
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.
Industry best practice procedures were followed and included submitting
blanks at, field duplicates and Certified Reference Material. Acceptable
levels of accuracy and precision have been confirmed.
Verification
of sampling
and
assaying
The verification of significant
intersections by either
independent or alternative
company personnel.
All assays are reviewed by the Competent Person and significant intercepts
are calculated as composites >0 5g/t Au with a minimum width of 3m.
Composites are produced through the Database export process and verified
by the Competent Person.
The use of twinned holes. No twin holes have been drilled.
Documentation of primary data,
data entry procedures, data
verification, data storage (physical
and electronic) protocols.
All drill hole logging was completed on paper logging sheets and entered into
spreadsheets before importation into the company Datashed database.
Copies of all paper logs are on record.
Discuss any adjustment to assay
data.
No assay data was adjusted, and no averaging was employed.
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.
Drill hole collars were located using handheld GPS with 3-5m accuracy and
initial Dip and Azimuth determined using a handheld compass. A Reflex EZ
Shot downhole survey tool was used to record drill hole deviation at intervals
of 50m.
Specification of the grid system
used
Drill hole collars are recorded in WGS84 UTM Zone 30.
Quality and adequacy of
topographic control
RL recorded from handheld GPS and SRTM data.
Data
spacing and
distribution
Data spacing for reporting of
Exploration Results.
Drill hole spacing is variable depending on the location within the project.
Whether the data spacing and
distribution is sufficient to
establish the degree of geological
and grade continuity appropriate
for the Mineral Resource and Ore
Reserve estimation procedure(s)
and classifications applied.
The drill hole spacing is not considered sufficient to establish the required
degree of geological and grade continuity for the estimation of mineral
resources.
Whether sample compositing has

Samples were composited upon collection into 4m intervals in the case of
RC and Aircore samples. Significant intercepts represent composites
compiled on 3m minimum interval and a cut-off grade of 0.5g/t Au.
Orientation

sampling of possible structures
Drill holes were generally oriented perpendicular to the strike of geology and
shallow dips of drilling were used to intersect the structures at a high angle.

CRITERIA EXPLANATION COMMENTARY
geological
structure
and the extent to which this is
known, considering the deposit
type.
If the relationship between the
drilling orientation and the
orientation of key mineralised
structures is considered to have
introduced a sampling bias, this
should be assessed and reported
if material.
As drill holes were generally drilled perpendicular to the strike of
mineralisation it is not believed that there has been any sampling bias
introduced based on the current understanding of the structural orientations
and the dip and strike of mineralisation.
Sample
Security
The measures taken to ensure
sample security.
Drill samples were collected by Company personnel directly from the drilling
rig and transported to the exploration camp for processing. Prepared
samples were then transported directly to the laboratory by road by
representatives of the company. Other than sub sampling in the form of core
cutting, no sample preparation was conducted by the company.
Audits or
reviews
The results of any audits or
reviews of sampling techniques
and data.
No audits have been carried out.

Type, reference name/number,
location and ownership including
agreements or material issues
with third parties such as joint
ventures, partnerships, overriding
royalties, native title interests,
historical sites, wilderness or

The Bouaflé Project licences are currently under application. The applications are denominated on the Ivoirian cadastre by PR0822 and PR0861 held under Rampage Resources which is a local subsidiary of West African Venture Investments, with whom the Company is in a joint venture.
Further details of the joint venture can be found in the ASX announcement of September 8th 2020.
The security of the tenure held at
the time of reporting along with
any known impediments to
obtaining a licence to operate in
the area.
Both licences are held under application as above.
Exploration

parties
Acknowledgment and appraisal of
exploration by other parties.
Historical exploration was carried out by Equigold which was ultimately a subsidiary of Newcrest Mining Limited. This exploration was generally carried out to industry best practice.
Geology Deposit type, geological setting
and style of mineralisation
The Bouaflé mineralisation generally fits the Orogenic hosted Gold deposit model as applied to the Birimian systems of West Africa.
Drill hole
information
A summary of all information

the exploration results including a
tabulation of the following
All relevant drill hole details are provided in Table 1 above.

CRITERIA EXPLANATION COMMENTARY
information for all Material drill
holes:
o easting and northing of the drill hole collar
o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
Data
aggregation
methods
In reporting Exploration Results,
weighting averaging techniques,
maximum and/or minimum grade
truncations (eg cutting of high
grades) and cut-off grades are
usually Material and should be
stated.
Significant intercepts are determined above a 0.5g/t Au cut-off grade with
minimum 3m intercept and maximum 3m internal waste. No top cuts have
been applied.
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.
As above.
The assumptions used for any
reporting of metal equivalent
values should be clearly stated.
No metal equivalents are 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 only the down
hole lengths are reported, there
should be a clear statement to this
effect (eg ‘down hole length, true
width not known’).
All intercepts reported as downhole lengths. True widths of mineralisation
have not yet been determined.
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.
Balanced
reporting
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.
All significant intercepts as defined above have been reported.
Other
substantive
exploration
data
Other exploration data, if
meaningful and material, should
be reported including (but not
limited to): geological
observations; geophysical survey
results; geochemical survey
results; bulk samples – size and
method of treatment; metallurgical
test results; bulk density,
groundwater, geotechnical and
rock characteristics; potential
deleterious or contaminating
substances.
Geophysics, summary results of soil geochemistry and geology as available
have all been reported in full. No other studies have yet been completed.
Further work The nature and scale of planned
further work (eg tests for lateral
extensions or depth extensions or
large-scale step-out drilling).
Diagrams clearly highlighting the
areas of possible extensions,
including the main geological
interpretations and future drilling
areas, provided this information is
not commercially sensitive.
Further work is dependent on the license grant process. This is expected to
include further mapping, soil geochemistry and reconnaissance drilling to
follow up on significant intercepts.
