Duke Exploration : Prairie Creek Assay Results Confirm Epithermal Gold

ASX ANNOUNCEMENT | ASX: DEX		Media Release
	29 November 2021

only		PRAIRIE CREEK ASSAY RESULTS CONFIRM EPITHERMAL GOLD
Duke Exploration Limited (ASX: DEX) ("Duke" or "the Company") is pleased to announce assay results
use	from the remaining two diamond exploration holes recently drilled at the Company's Prairie Creek
Gold Project in Central Queensland, targeting a 1.6 km long 200 m wide NE trending gold in soil
	anomaly (0.5 - 5.0 g/t Au). This announcement follows on from results from the first hole
	announced on 22 September.
		HIGHLIGHTS
personal		• Zones of epithermal-style quartz veining and breccias and associated gold mineralisation
	were intersected in diamond drill holes.
		• The intersections include:
		o 7 m at 31.17 g/t Ag from 0.0 m in PCDD002
		o 4.0 m at 0.59 g/t Au from 0.0 m in PCDD003
		o 2.4 m at 0.71 g/t Au from 16.0 m in PCDD003
		o 1 m at 0.54 g/t Au from 37.4 m in PCDD003, and
		o 2.1 m at 1.64 g/t Ag from 52.9 m in PCDD003
		• These are in addition to previously reported intersections from PCDD001:
		o 2.30 m at 4.68 g/t Au from 7.00 m
		o 20.40 m at 1.86 g/t Au from 11.40
		o 5.35 m at 2.95 g/t Au from 38.10
	Commenting on progress - Philip Condon, MD:
	"The Prairie Creek project drilling programme strategy was to confirm previous exploration results
	and to gain an understanding of the geology and style of gold mineralisation, so we can begin to
	evaluate the project potential for an economic mining operation. Three diamond holes were
	planned and drilled in the vicinity of historic high-grade drill intercepts in RC drilling to achieve that
	goal. Geological logging and assay results confirm that epithermal-style gold mineralisation is
Forpresent and provides the impetus for further work on the project. Follow-up will be focused on

geological mapping and interpretation and expanding soil geochemistry to define other targets. The diamond rig is now drilling at Duke's Bundarra project."

Technical Information

Prairie Creek Gold Project Exploration Drilling Details

The Prairie Creek Project is located 120km 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.

The Prairie Creek prospect is the highest priority target within the project area (Figure 1 and Figure 2; see www.duke-exploration.com.aufor project details). The prosect was historically identified from stream sediment sampling and is defined by a NE trending high grade gold in 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 mineralisation style is interpreted as a gold-rich epithermal system containing minor silver associated with colloform quartz veining and breccia fill within a chlorite-hematite-k-feldspar-sericite altered volcaniclastic. 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 included:

• 13.3 m @ 2.81 g/t Au from 55.3 m in DD93GW9
• 20 m @ 1.18 g/t Au from 20 m in RC93GW3
• 8 m @ 2.09 g/t Au from 60 m in RC93GW7
• 52 m @ 2.11 g/t Au from 52 m in RC93GW5, including 10 m @ 3.2 g/t Au and 6 m @ 6.55 g/t Au.

Duke's drilling program comprised three diamond holes for a total of 363.3 m, which were drilled over 30 days. A total of 405 samples were sent to ALS Global's laboratory in Townsville, with all assays now returned (Table 2 and Figure 3). Best gold and silver intersections from all holes include (Table 2 and Figure 3):

• 4.0 m at 0.66 g/t Au from 0.0 m in PCDD001, (previously reported)
• 2.3 m at 4.68 g/t Au from 7.0 m in PCDD001, (previously reported)
• 20.4 m at 1.86 g/t Au from 11.4 m in PCDD001, (previously reported)
• 5.4 m at 2.95 g/t Au from 38.1 m in PCDD001, (previously reported)
• 7 m at 31.17 g/t Ag from 0.0 m in PCDD002,
• 4.0 m at 0.59 g/t Au from 0.0 m in PCDD003,
• 2.4 m at 0.71 g/t Au from 16.0 m in PCDD003,
• 1 m at 0.54 g/t Au from 37.4 m in PCDD003, and
• 2.1 m at 1.64 g/t Ag from 52.9 m in PCDD003

Table 1. Duke Exploration diamond drill collar details

The three diamond drill holes from the current program intersected a succession comprising an upper volcaniclastic conglomerate/breccia dominated unit and a lower more massive unit interpreted as a K- feldspar-hematite altered crystal tuff of the Torsdale Volcanics that are cross-cut by intrusions of mafic and syenitic composition up 10 m thick (Figure 3).

Gold-silver mineralisation is associated with breccia zones that have colloform banded quartz vein infill (Figure 4 and Figure 5). These breccias mostly occur within the upper volcaniclastic unit although PCDD001 did intersect one zone in the lower unit. Breccias overprint earlier chlorite-hematite±sericite±k-feldspar alteration in the host volcaniclastics. No wider veins were intersected and there is no clear structural control on the gold mineralisation other than the spatial relationship to breccia zones. Other colloform quartz infill breccias and veins were also noted in core that did not have associated gold mineralisation. Colloform quartz textures
