MULTI-DEPOSIT POTENTIAL GROWS onlyWITH STRONG REGIONAL GOLD RESULTS
Predictive Discovery Limited ("Predictive" or "Company") is pleased to announce highly encouraging new drill results from regional aircore (AC) drilling testing multiple prospects at its Bankan Gold Project (Figure 1), located in Guinea.
BACKGROUND | |||
use | • Regional drilling has been following up ten structural targets identified by the 2021 aeromagnetic | ||
survey along with additional geochemical targets within 3km of the NE Bankan deposit. Shallow gold | |||
mineralisation has been discovered on most areas drilled to date. | |||
• Follow-up aircore (AC) drilling has obtained substantial gold intercepts on four prospects so far: 800W, | |||
SW Bankan, Bankan Creek North and AG2, three of which are within 3km of NE Bankan. All are open | |||
along strike and at depth and require follow-up deeper drilling. | |||
• Two of the original structural targets remain untested by any drilling method and ongoing analysis of | |||
geophysical and geological data continues to identify new structural targets across the Bankan Project. | |||

Executive Director, Paul Roberts said:
only"The Bankan Project is at a very exciting stage. Adding to the ongoing, deep drill success at NE Bankan, AC drilling of the Bankan regional prospects continues to identify new, highly encouraging zones of gold mineralisation. With further drilling and the improved geological understanding that flows from that, these prospects are expected to add significantly to the Bankan Project's mineral resource inventory.
Near NE Bankan, at 800W, new drill results have identified a broad zone of shallow, ENE-trending gold mineralisation which is open along strike and at depth. Further to the north, on the AG2 prospect, new zones of gold mineralisation have emerged in several separate locations, some on structurally controlled contacts
usewith mafic rocks.
All of the previously discovered prospects and new discoveries require follow-up AC and RC drilling while ongoing auger drilling continues to test new structural positions with the aim of uncovering yet more new gold mineralised zones."

Bankan Regional Exploration: Background
onlySituated in north-east Guinea, the Bankan Project covers 365km2 across four Exploration Permits (Figure 1). Initial discovery of the now 3.3Moz NE Bankan gold discovery1 was announced in April 20202. Following the NE Bankan discovery, Predictive quickly completed a series of early-stage exploration programs, including broad spaced auger drilling and a helicopter-borne magnetic and radiometric survey. The aeromagnetics identified a major 35km-longnorth-northwest structural corridor with the potential to host multiple "NE Bankan-style" discoveries.
useStructural targets identified using the aeromagnetics have been progressively followed up with power auger and aircore drilling. The strategy to date has been to undertake wide-spaced auger drilling covering the tructural targets, typically 320m x 80m, followed by closer spaced infill where encouraging gold results have been obtained (generally plus 0.25g/t composite values in saprolite to depths of around 20m.
AC drilling has then followed up the encouraging auger results, typically with pairs of scissor holes to help assess the orientation of the gold mineralisation.
personalTen structural targets have been at least partially drilled so far and two remain untested. Ongoing structural analysis based on the aeromagnetic survey continues to identify new areas of interest. This process has
yielded numerous gold prospects, the most promising to date being 800W, SW Bankan, AG2, and N-BCK (Figure 1). Earlier results from 800W and SW Bankan included the following:

Near NE Bankan Prospects (800W, N-NEB,N-BCK,S-NEB)
These prospects are all located within 3km of the NE Bankan deposit (Fig. 1) and contain gold mineralisation with potential to add significant shallow resource ounces to the Bankan Project.
The drill program at 800W was designed to follow-up on gold mineralisation previously intersected on two adjacent section lines (see above). A total of 27 AC holes (totalling 1,294m) were completed on 6 traverses
at 80m spacing.
personalWhat has emerged is a broad, ENE-trending zone of gold mineralisation which remains open along strike and to depth. This is a different mineralised strike direction to what has been observed at NE Bankan and
Bankan Creek and potentially represents a different style of gold mineralisation.
Reinterpretation of aeromagnetic data suggests that mineralisation distribution is possibly controlled by an ENE magnetic linear (Figure 2) which may represent a rock type change. While the apparent dip on section is shallow to the west, the true dip of gold mineralisation may be steeper to the NNW.
Figures 2-5 show a plan view of the gold mineralisation discovered to date along with three cross-sections 40m apart. All the drilling is in deeply weathered material and the primary host rock to gold mineralisation is not yet known.
Further drilling is now required to test along strike and at depth, drilling in a SSE direction. Deeper RC and diamond drilling is planned to better define the geology and test this new gold mineralised zone at depth.
