BANKAN AEROMAGNETICS IDENTIFIES NUMEROUS DRILL TARGETS ALONG 35KM-LONG STRUCTURAL CORRIDOR

  • 9 high priority regional gold drill targets identified from recently completed aeromagnetic survey, flown across the Bankan Project, located in Guinea.
  • New targets are located on interpreted ENE-WSW faults, crosscutting a newly recognised major 35km-long north-northwest structural corridor with the potential to host numerous "NE Bankan-style" discoveries.
  • Newly identified lithological and structural elements controlling mineralisation at NE Bankan have provided a model for gold discovery across the Bankan Project.
  • 15,000m of regional power auger drilling underway, with auger grids testing nine new targets designed to outline further gold auger footprints.

Figure 1 – Location diagram of Bankan Project with aeromagnetic data overlain by nine new high priority gold targets.

Managing Director Paul Roberts commented: "As we continue to make excellent progress with deeper drilling at NE Bankan in preparation for the Maiden Resource Estimate, we are increasing our exploration on gold targets across the Bankan Project, where there is enormous potential to make new gold discoveries in areas which have never been drilled before.

The recent aeromagnetic survey has demonstrated why the NE Bankan deposit is in such prospective gold ground and delivered us much a better approach for selectively targeting new, NE Bankan-like prospects along strike to the north and south. Some of the new targets are coincident with shallow artisanal mine pits similar to the workings we encountered over part of the NE Bankan deposit prior to the drill discovery."

Predictive Discovery Limited (ASX: PDI, Predictive or the Company) is pleased to announce that a recently completed 3,384 line-kilometre airborne magnetic and radiometric survey has identified nine, high priority new targets within the Bankan Project, located in Guinea.

The Company is also pleased to report results of six Reverse Circulation (RC) drillholes totalling 735m at Bankan Creek, which have extended the strike length of the known mineralisation to more than 300m.

Aeromagnetic Survey and Targeting Study

A helicopter-borne magnetic and radiometric survey was conducted by New Resolution Geophysics (NRG™) in February covering the Bankan project area on a 100m-line spacing.

The geophysical data has been processed and an initial geological interpretation and target generation program has been carried out. Project-level aeromagnetic and interpreted geological maps are provided in Figures 1-3. Additional survey details are provided in Table 3.

Images of processed aeromagnetic data show lithological and structural features that may have controlled the localisation of the known gold mineralisation.

A particularly notable interpreted regional geological feature is a 35km-long NNW-orientated structural trend that traverses all four permits and passes to the east of the NE Bankan gold deposit. This structure appears to form the western margin of the Siguiri Basin in the northern part of the project area (Figure 2). It lies sub-parallel to possible related "second order" structures at the NE Bankan deposit itself (Figure 3).

A more detailed examination of processed data and geological interpretation from the immediate NE Bankan area show that gold mineralisation coincides with the following (see Figure 3):

• Intersection of a series of ENE-orientated and NW orientated magnetic linears, and

• A contact between granitic rocks and mafic volcanics,

both of which provide useful guidance for prioritising other targets within the project area.

These observations along with additional interpretation by Predictive's Chief Geologist Dr Barry Murphy using the Company's PredictoreTM methodology, has resulted in identification of nine high priority target areas, some of which coincide with known artisanal workings, along with numerous lower priority targets to be followed up in the future.

The Company has now deployed two auger rigs to follow-up on the new targets with more than 15,000m of auger drilling programmed for completion in the coming months with an initial focus on the AG1, AG2 and KA1 targets (Figures1- 2). Auger is fast, relatively cheap, and was the drilling discovery method for the NE Bankan deposit, providing the Company with strong confidence in the effectiveness of auger for making new discoveries at the Bankan Project.

Bankan Creek Extensional Drilling

Results have been received from the final six RC holes drilled at Bankan Creek totalling 735m. The holes were part of a 7-hole program designed to test for northern and southern extensions to the known Bankan Creek gold mineralised system and were drilled to a maximum down-hole length of 150m. Encouraging intercepts were obtained at the southern end of the prospect (see Table 1; Figures 5-6), including:

BCKRC0003

  • 17m @ 1.08g/t Au from 18m,
  • 6m @ 2.10g/t Au from 49m, and
  • 8m @ 0.56g/t Au from 92m (gold mineralised to end of hole)

BCKRC0005A

• 8m @ 2.88g/t Au from 9m including 1m @14.9g/t Au

BCKRC0007

• 3m at 3.24g/t Au from 90m

The drilling was carried out using a large, multipurpose (RC-DD) drill rig operated by Capital Drilling. Samples were assayed at the SGS laboratory in Bamako, Mali. More detailed information is provided in Tables 1 and 2.

There is very limited outcrop in the immediate area but based on the small
number of geological observations and the overall strike of the anomaly, an
east west line orientation with holes inclined to the west was considered most
likely to test the target mineralised zone. Results from earlier drilling has now
determined that the overall dip of the gold mineralised envelope is to the
west. All drill holes reported in this release were drilled from WSW to ENE to
obtain near-true widths through the gold mineralisation.

Reporting
Where comprehensive reporting of all
Exploration Resultsis not practicable,
representative reporting of both low and
high grades and/or widthsshould be
practiced to avoid misleading reporting of
Exploration Results.
Not applicable to geophysical survey.
Other
Substantive
Exploration
Data
Other exploration data, if meaningful and
material, should be reported including (but
not limited to): geological observations;
geophysicalsurvey 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.
All other exploration data on this area has been reported previously by
PDI.
Further Work The nature and scale of planned further
work (eg tests for lateral 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.
These results form part of an ongoing exploration program conducted to
explore the Bankan Project permits for gold mineralisation similar to that
already discovered at the NE Bankan and Bankan Creek prospects.
