Mr Paul Roberts, PDI’s Managing Director said: “This program was planned to make low cost, shallow drill tests of multiple targets. Most of the drill holes were less than 30m deep and we have also demonstrated good hole-to-hole continuity in at least three of the new prospects. The next step is to follow up the new gold discoveries with deeper drilling along strike and down-dip with the aim of delineating new resources to add to the high-grade Bongou discovery[1] .”
1184,000oz in the Inferred and Indicated Mineral Resource categories with an average grade of 2.6g/t Au including 136,000oz at 3.8g/t Au (ASX release dated 4 September, 2014).

INTRODUCTION
PDI has identified nearly 100 exploration targets near the high grade Bongou gold discovery[1] (Figure 1) through a rigorous ranking process focused on prospects with Bongou-like geological and geophysical characteristics.

Drill Program Results
A 3,854m drill program consisting of reverse circulation (RC) and limited air core drilling was carried out in May-June 2015. The program was conducted using a UDR650 drill rig with both RC and air core drill capabilities. The drilling tested nine targets in six different areas as follows:
Target 92 (see Figure 1 for location)
This prospect was identified as a high priority location in PDI’s Bonsiega rainy season project review in 2014. The target area overlaps a large area of surficial artisanal gold workings and coincides with a large east-west structure interpreted from magnetic data. PDI’s exploration around Bongou in 2014 showed that such east-west features may have controlled the location of gold mineralisation in this area.

Power auger drilling in March and April 2015 revealed a 3km long gold anomalous area at a 25ppb Au cut-off (Figure 2).

Shallow RC drilling was carried out on widely spaced cross sections, testing areas with better values in power auger drilling. Better intercepts included:
-
TBFRC004: 2m at 3.27g/t Au from 0m and 2m at 2.03g/t Au from 10m.
-
TBFRC010: 3m at 3.91g/t Au from 17m, including 1m at 10.75g/t Au (last metre drilled).
-
TBFRC011: 9m at 2.83g/t Au from 4m, including 1m at 11.80g/t Au.

Figure 3: Target 92 – cross section through the encouraging TBFRC010 and TBFRC011 drill intercepts.
The better mineralisation intersected in holes TBRC010 and TBRC011 is hosted within gabbro on the margins of steeply dipping diorite bodies (Figure 3). This is an interesting new style of mineralisation with some geological similarities to Bongou. The zone is open in all directions, including for at least 600m along strike to the east and west. The presence of higher grades in both holes is certainly encouraging. The mineralisation will be followed up with drilling along strike and at depth in the next program.

Prospect 71 (see Figure 1 for location)
This prospect lies near the northern edge of a large gold geochemical anomaly covering 2.4km[2] (Figure 4). Close spaced power auger drilling and ground magnetic surveys in early 2015 revealed two sub-parallel NW striking structures within the broader anomaly. Of these, the southern zone contains a series of strongly anomalous power auger values including 4.7g/t Au and 1.8g/t Au (ASX releases dated 20 February 2015 and 24 April 2015).

The pre-2015 results were prepared and first disclosed under the JORC Code 2004; they have not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported).
The 2015 drilling program (Figure 4), totalling 911m, was designed to test both of the targeted structures. The best results were obtained in a cross section through the southern zone (Figure 5), and included:
-
PSORC056: 6m at 2.25g/t Au from 19m, including 1m at 6.80g/t Au . Stopped in gold mineralisation
-
PSORC058: 4m at 3.32g/t Au from 10m, including 1m at 9.22g/t Au.

==> picture [596 x 77] intentionally omitted <==
PSORC060: 14m at 0.84g/t Au from 0m, including 3m at 2.70g/t Au.
This drilling showed a clearly defined shallow dipping gold mineralised zone, which correlates well from hole to hole (Figure 5). The mineralisation appears to strike NW. Drilling on a parallel section 110m to the SE revealed several similar, sub-parallel shallowly dipping zones, including 5m at 1.09g/t Au and 24m at 0.47g/t Au in hole PSORC051 (Figure 4). This mineralisation appears to correlate with the mineralisation drilled in PSORC056, indicating that this newly discovered gold zone is open to the south-east.
The dip and strike of the newly discovered mineralisation is entirely new for the area and provides a possible explanation for the wide area of gold anomalism at Prospect 71. Earlier drilling was designed to test at right angles to steep dipping, NNE-striking mineralised structures mapped in artisanal mining workings. It is now clear that the earlier drill lines were not optimally oriented. Despite this, several gold intercepts were obtained from the earlier drilling, most notably PSORC030 which contained 4m at 7.02g/t Au from 20m[2] . This suggests that there is ample opportunity to discover more zones of similar, shallow-dipping gold mineralisation within the Prospect 71 anomaly.

Bongou (See Figure 6 for location)
Bongou W2
This target is located 600m from Bongou where PDI has reported a high-grade Indicated and Inferred Resource of 184,000oz at 2.6g/t Au (reported to the ASX on 4[th] September 2014). The W2 target was initially identified by power auger drilling in 2013 and followed up with trenching. In 2014, a single RC hole intersected 12m at 1.4 g/t Au (reported to the ASX on 1[st] April 2014).
Three additional RC holes, totalling 241m, were drilled on section lines approximately 50m apart, with the following results:
-
BNGRC025: 2m at 3.40g/t Au from 10m, including 1m at 6.17g/t Au.
-
BNGRC026: 9m at 1.27g/t Au , including 1m at 5.22g/t Au .
-
BNGRC027: 21m at 0.98g/t Au , including 8m at 1.57g/t Au .
This drilling showed that the mineralisation is open to the west in what appears to be an ENE trending shear zone cutting through the granite. Geological interpretation based on power auger drilling through thin cover indicates that the inferred shear zone is likely to persist to the WSW within granite for at least 150m (Figure 7). The mineralisation dips almost vertically indicating good down-dip continuity (Figure 8).

Calculated Resources at the Bongou Deposit consist of 184,000oz at 2.6g/t including 138,000oz at 3.8g/t Au in the Indicated and Inferred Resource categories (reported to the ASX on 4[th] September, 2014).

Bongou W8
This target is located 2km WNW of Bongou (Figure 6). It coincides with a 60m long artisanal open pit working and gold anomalous values in power auger drilling and trenches. Four RC holes, totalling 341m, were drilled on section lines approximately 50m apart, with the following best results:
-
BNGRC023: 8m at 1.65g/t Au from 18m, including 1m at 5.26g/t Au .
-
BNGRC024: 8m at 0.72g/t Au from 40m, including 3m at 1.51g/t Au .
The BNGRC023 is located on the westernmost drill line and the mineralised zone is therefore open to the west and at depth.
Bongou Other
Two holes approximately 50m apart were drilled at Bongou W7 and one hole was drilled southwest of the Bongou open pit. None of these holes contained a reportable gold intersection.
Targets 4, 11 and 75 (see Figure 1 for locations)
RC drilling, totalling 1,320m, at these three locations identified:
-
Target 11: anomalous gold in 8 out of 12 holes, including:
-
LATRC057: 7m at 1.34g/t Au from 8m, including 4m at 2.05g/t Au , and
-
LATRC059: 2m at 2.10g/t Au from 7m.
-
Target 75: anomalous gold in 4 out of 11 holes but with no results exceeding 1g/t Au.
-
Target 4: a large, Bongou-like altered granite zone with disseminated sulphides and probably extending over more than 500m of strike length but with no anomalous gold values.
Future Work
With the onset of the rainy season, PDI’s exploration program in Burkina Faso for the 2014-15 field season is now complete. The Company will now undertake a project-wide assessment of all drill results to date before designing the next drill program. The next program will be focused on building on these results to delineate resources that can add to the already defined Bongou high grade gold resource[3] .

Commentary | |
| Sampling Technique Drilling |
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 downhole 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 detailedinformation. |
All of the sampling described in this report refers to either reverse circulation (RC) drill samples or air core (AC) drill samples. Both methods were used to obtain either 4m or1 m samples were obtained, and from each of which 2 kg was pulverised to produce a 50 g charge for fire assay. In the first place, all holes were composite sampled using a soil scoop plunged into each sample bag. Composite samples usually consisted of 4m each. At the same time, riffle splitting of each 1m interval was employed to produce representative one metre samples, each of 2kg. The riffle split 1m samples from the composite scoop samples which returned higher gold values (generally >0.5g/t Au) were re-assayed to ensure that more representative samples of the mineralised intercepts of potential economic interest had been assayed. The drill samples are judged to be representative of the rock being drilled because representative sub-sampling of both the RC and air core samples was achieved. |
| 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,bywhat method,etc). |
RC and AC drilling were carried out using a 4.5 inch face sampling hammer and a 4.5 inch blade bit, respectively. |

| 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. |
Sample recovery was estimated for all samples. RC recoveries were estimated by weighing the samples and estimating the recovery based on the likely in situ density of the material and the known volume of the drill hole Sample recovery was maximised in the RC drilling by use of a face sampling hammer. |
|---|---|---|
| Logging | Whether core and chip samples have been geologically and geotechnical 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 (or costean/Trench, channel, etc) photography. The total length and percentage of the relevant intersections logged. |
Detailed geological logging has been carried out on all drill samples, recording lithology, weathering, structure, veining and/or mineralisation, grainsize and colour. Logging of sulphide mineralization and veining is quantitative. No judgement has yet been made by independent qualified consultants on whether the geological and geotechnical logging has been sufficient to support Mineral Resource estimation, mining and metallurgical studies. |
| Sub-Sampling Technique and Sample Preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. 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. |
An on-site riffle splitter was employed to produce a 2kg assay sample for submission to SGS. Either one or two reference riffle-split 2kg samples are retained from the RC samples for future re-assay or metallurgical testwork. The sampling (and analytical) methods were appropriate for the style of mineralisation, especially as no visible gold has been observed. |

| 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. |
All samples were assayed for gold by 50g fire assay at the SGS laboratory in Ouagadougou, Burkina Faso. The technique is considered a total analysis. No geophysical tools, spectrometers or handheld XRF instruments have yet been employed. Unlabelled standards, blank and duplicate samples were submitted with all assay batches, generally at the rate of one standard every 15thsample. Where any problems with bias or accuracy, especially outside of a +/- 10% envelope is observed, samples are re-assayed. External laboratory checks are planned but have not yet been carried out. |
|---|---|---|
| Verification of Sampling and Assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes The verification of significant intersections by either independent or alternative company personnel. Discuss any adjustment to assay data |
No holes have yet been twinned. Field data collection is undertaken by the company’s Burkina Faso-based geologists. All results are checked by Mr Paul Roberts, the company’s Managing Director. |
| Location of Data points |
Accuracy and quality of surveysused tolocate drill holes (collar and down- hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used Quality and adequacy of topographic control |
Collar positions were located using a hand held GPS with a location error of +/- 3m. Collar coordinates listed in the table are for Universal Transverse Mercator (UTM), Datum WGS 84, Zone 31 - Northern Hemisphere. |
| Data Spacing and Distribution |
Data spacing for reporting of Exploration Results 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. Whether sample compositing has beenapplied |
The drill intercepts are irregularly spaced. Drill spacing along lines was “heel to toe” i.e. the hole collar spacing was designed such that the bottom of each hole would be approximately below the collar of the next hole – in order to provide complete drill coverage. For example, this would generally mean that 20m long 60 degree angled holes would have collars spaced 20m apart. Given that this was a reconnaissance program, drill line spacings were very variable – from 50m to 600m. No judgement has yet been made by an independent qualified consultant on whether the drill density is sufficient to calculate a Mineral Resource. Sample compositing was applied as described elsewhere in this table. |
| Orientation of Data in Relation to Geological Structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures 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. |
All drill holes reported here were drilled approximately at right angles to the anticipated strike of the target mineralization. In most prospects, the target mineralisation lies under cover. For this reason, there is a risk that the drill orientation was not optimal.t |

| Sample Security | The measures taken to ensure sample security |
The large RC sample bags are stored at a sample farm on PDI’s exploration permits. These are guarded by local individuals hired for this purpose. 2kg reference samples are stored at the company’s field camp in the town of Gayeri, which is guarded 24 hours per day. Pulp samples are retained at company premises in Ouagadougou which are also guarded 24 hours perday. |

| Mineral Tenement and Land Tenure Status |
Type, reference name/number, location and ownership including agreements or material issues with third partiessuch asjoint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. 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. |
The locations reported here lie within the Sirba Permit (Arrêté N°2014/14/296/MCE/SG/DGMGC) which covers an area of 137 sq km, Madyabari Permit (Arrêté N°2014/14/295/MCE/SG/DGMGC) which covers an area of 172 sq km and the Basieri permit (Arrete No. 2013- 16/MCE/SG/DGMGC ) which covers an area of 73.5 sq km. There are no overriding reserves or national parks over this permit. In a future mining operation, the Government of Burkina Faso is entitled to a 10% share of any mine along with a 3-5% ad valorem royalty, the percentage of which is determined by the gold price prevailing at the time. The company believes that (a) the permit is securely held as it has complied with all the necessary government requirements and (b) the permit can be replaced in due course by a mining licence as long as a feasibility study shows that a future mine would be viable and that company completes meets the Government’s legal requirements, which it fully intends to do.. The Sirba and Madyabari permits were initially acquired, along with two other nearby permits (Fouli and Tantiabongou), by Birrimian Pty Ltd (Birrimian), which is a British Virgin Islands-registered company now 100% owned by PDI. The original owners of Birrimian subsequently entered into an agreement with Eldore Mining Corporation Limited (Eldore) through which Eldore could acquire the Birrimian permits through a series of payments and a commitment to issue US$2 million worth of Eldore stock on completion of a Bankable Feasibility Study on one or more ore deposits within the Birrimian permits. PDI initially acquired an interest in Sirba and Madyabari along with the two other Birrimian permits via a joint venture with Eldore which commenced in January 2010. In 2012, Eldore changed its name to Stratos Resources Limited (ASX: SAT) after which PDI bought out SAT’s residual interest (in late 2012). In acquiring Birrimian, PDI also inherited the one unfulfilled commitment in the original Eldore agreement with the original Birrimian shareholders.

| Geology | Deposit type, geological setting and style of mineralisation. |
Mineralisation is variable across the various prospects tested in this drill program, and consists of albite-silica altered granite containing disseminated pyrite near Bongou and weathered and (presumably) altered sheared gabbro elsewhere. The mineralisation is interpreted as a variant of the orogenic gold mineralisation style, which is known throughout the Birimian Belt of West Africa. |
| Drill Hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length • If the exclusion of this information is justified on the basis that the |
Intercepts that form the basis of this announcement are tabulated in Table 1 within the body of the announcement and incorporate Hole Number, Easting, Northing, Dip, Azimuth, Depth and Assay data for mineralised intervals. Appropriate locality maps accompany this announcement. |

| 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. 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. |
Over 95% of the gold mineralised material (with grades exceeding 0.5g/t Au) was sampled in intervals of one meter or less. No top cuts have been applied to exploration results as the maximum value in the entire assay database is 12g/t Au. Up to 4m (down-hole) of internal waste is included. Mineralised intervals are reported on a weighted average basis. |
| 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 (eg ‘down hole length, true width not known’). |
True widths have been estimated for all intercepts based on geological interpretation of the drill results and/or what seem to be the most logical correlation of gold values from hole to hole. |
| 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. |
Appropriate plans and cross sections are included in the text of this document. |
| 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 intercepts containing average gold grades exceeding 2g-m (e.g. 1 g/t Au over a down-hole width of 2m) are reported. Holes in which no significant result has been obtained are also routinely reported by PDI. |
| 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 |
No other work has yet been carried out on these prospects owing to the reconnaissance nature of the drilling program reported here. |

Predictive Discovery Limited (PDI) was established in late 2007 and listed on the ASX in December 2010. The Company is focused on exploration for gold in West Africa. The Company’s major focus is in Burkina Faso, West Africa where it has assembled a substantial regional ground position totalling 1,605km[2] and is exploring for large, open-pittable gold deposits. Exploration in eastern Burkina Faso has yielded a large portfolio of exciting gold prospects, including the high grade Bongou gold deposit on which a resource estimate was calculated in September 2014. PDI also has interests in a strategic portfolio of tenements in Côte D’Ivoire covering a total area of 1,533 km[2] .
