ASX ANNOUNCEMENT | ASX: DEX

22 September 2021

FIRST DRILL HOLE AT PRAIRIE CREEK INTERSECTS GOLD ZONES FROM SURFACE TO 150M DEPTH

Duke Exploration Limited (ASX: DEX) (“Duke” or “the Company”) is pleased to announce the assay results from the first of three diamond exploration holes recently drilled at the Company’s Prairie Creek Gold Project in Central Queensland, targeting a 1.6 km long 200m wide NE trending gold soil anomaly (0.5 – 5.0 g/t Au).

HIGHLIGHTS

• Six zones of epithermal gold mineralisation were intersected in the first exploration diamond drill hole completed by the Company at Prairie Creek from the surface to 150m down hole.

• The intersections include: o 2.30 m at 4.68 g/t Au from 7.00 m in PCDD001,

• 20.40 m at 1.86 g/t Au from 11.40 m in PCDD001 and

• o 5.35 m at 2.95 g/t Au from 38.10 m in PCDD001.

• The association of mercury and silver with the epithermal gold mineralisation suggests the hole has intersected the top of an epithermal low sulphidation gold system with exploration potential for deeper higher grade gold mineralisation associated with feeder veins to the breccia style gold intersected.

• Assays pending for 2 further holes

Managing Director Philip Condon commented:

“The Prairie Creek project drilling programme strategy is to confirm previous exploration results and to gain a critical understanding of the geology, so we can begin to evaluate the project potential for an economic mining operation. We planned and drilled three diamond holes to achieve that goal and the assays from the first hole are the first positive glimpse of the outcomes of that programme. The first hole has provided encouraging geological information that the depth potential at Prairie Creek may be significant and untested. We are looking forward to the results from the next two diamond holes, which will provide further detailed information on the geometry and trends of the epithermal gold zones intersected in the first hole and allow us to plan follow up exploration drilling. The diamond rig has moved to Mt Flora to complete two diamond drill holes to provide metallurgical samples for a definitive metallurgical test work programme. The rig will then start the next phase of

exploration drilling to test the new targets developed from our profile targeting techniques, which will lead to the prioritisation of the next resource development opportunity at the Bundarra project.”

Future Work Programme

• Finalise the timing of step-out extension RC resource drilling at the Mt Flora resource to test the new mineralisation discovered to the north.

• Continue accelerated pXRF soil sampling, to be completed by the end of the year, to sample the entire Bundarra Pluton to help prioritise resource development work.

• Accelerate and extend collection of electrical geophysical data over the entire Bundarra Pluton.

• Start exploration diamond drilling to collect geological data to confirm targets mapped to date and help prioritise resource development work.

• Start scout RC drilling to determine the highest priority target for resource development drilling.

• Provide all exploration diamond drilling assay results from the Prairie Creek gold project by the end of October.

This announcement has been authorised for release by the Board.

Technical Information

Prairie Creek Gold Project Exploration Drilling Details

The Prairie Creek Project is located 120 km southwest of Gladstone and 25 km southwest of Biloela, central Queensland, in EPM 26852 (Figure 1). This part of Central Queensland is prospective for epithermal gold mineralisation like the Cracow epithermal gold deposit 80 km to the south.

==> picture [541 x 384] intentionally omitted <==

Figure 1. Location of Prairie Creek project (EPM 26852)

The Prairie Creek gold prospect is the highest priority target within the project area (Figure 1 and Figure 2; see www.duke-exploration.com.au for project details). The prosect is highly anomalous in gold, as mapped by stream sediment and rock chip sampling and is defined by a NE trending elevated gold geochemical soil anomaly (0.5 – 5.0 g/t Au), extending over a strike length of 1.6 km and with a width of 200 m. The project is interpreted to be a gold rich epithermal system containing gold and silver associated with quartz-epidotechlorite veining. Historic drilling has been carried out on the southern end of the soil anomaly, but the extent and continuity beyond this outcrop has not been tested. Significant intersections in historic drilling, include 52m @ 2.11g/t Au, including 10m @ 3.2g/t Au and 6m @ 6.55g/t Au.

The diamond drill rig mobilised to site and started drilling on Saturday 31 July 2021. The programme comprised three diamond holes for 350 m that were planned to:

• Confirm the historic drill hole results and location of the historic holes.

• Document the geology, particularly structural trends and potential continuity of mineralisation.

• Collect petrophysical and geochemical downhole survey data to better understand the style and genesis of the gold mineralisation.

• Measure orientations of structures that hosts gold mineralisation in 3D downhole.

• Log the local geology and use the geology, geochemistry and petrophysical data from the drilling to mapping the 3D geology.

• Better understand the potential controls on mineralisation and potential for resource development.

A total of over 363.3 m were drilled over 30 days, averaging 12.3 m per day, which includes breakdowns and weather delays compared to the drill plan of 350 m. A total of 405 samples were sent to the laboratory in Townsville, with 160 assay results returned to date from the first hole, PCD001 (Table 1 and Table 2 and Figure 2 and Figure 3). Better intersections from the new drilling include (Table 2 and Figure 3):

• 4.0 m at 0.66 g/t Au from 0.0 m in PCDD001,

• 2.3 m at 4.68 g/t Au from 7.0 m in PCDD001,

• 20.4 m at 1.86 g/t Au from 11.4 m in PCDD001 and

• • 5.4 m at 2.95 g/t Au from 38.1 m in PCDD001.

Table 1. Prairie Creek new exploration diamond drill collar details

The first hole intersected andesitic tuff, volcaniclastics and acid tuff from the Torsdale volcanics that are intruded by younger porphyry dykes and a syenite intrusive at around 100m depth (Figure 3). Epithermal colloform quartz veins contain the gold mineralisation (Figure 4 and Figure 5), mainly hosted by the volcanic rocks but also occur in the underlying syenite (Figure 3). Six zones of gold mineralisation were intersected from the surface to a down hole depth of 151.2 m, with all rock types mineralised (Figure 3). The wider zones of gold mineralisation from the surface to 50 m down hole are associated with brecciated volcanoclastic and tuffaceous lithologies. The breccias are cemented by epithermal quartz veins with classic epithermal colloform textures (Figure 4 and Figure 5). The gold mineralisation is associated with anomalous silver and mercury, which along with the breccia and epithermal colloform textures suggest this part of the Prairie Creek gold anomaly is at the top of an epithermal system, with potential for vein hosted gold mineralisation like the Cracow epithermal gold deposit deeper in the system.

Table 3. Mount Flora Mineral Resource Summary

The exploration and development strategy is to define sufficient resources at Mt Flora and the other prospective targets in the Bundarra project area as a priority to allow feasibility studies to be undertaken to establish an economic mining operation and to delineate additional mineral resources from the current known exploration target areas to grow the project into the future. The Company has also started to test the more conceptual exploration targets on the Prairie Creek project and Red Hill project (see www.dukeexploration.com.aufor more project details). The business development strategy for the Company is to focus on the Bundarra project and simultaneously carry out resource development work on those targets evaluated and ranked as high priority, starting at Mt Flora, while exploring the regional potential of the Bundarra pluton.

Duke Exploration Limited www.duke-exploration.com.au

The aim is to discover a pipeline of resource development projects around the Bundarra pluton to add to the Mt Flora project organically.

pXRF soil sampling and gradient array resistivity and induced polarization (GAIP) surveys continue to be carried out to the north, south and east of the current survey areas around the northern and eastern contacts of the Bundarra pluton. The aim is to accelerate the collection of pXRF soil data and electrical geophysical data to map the entire prospective area of the Bundarra pluton to allow computer-based machine learning statistical analysis to be carried out to help target the highest priority targets for resource development drilling into the future.
