Misima Resource drilling delivers additional high-grade gold and silver assays

Mineral Resource and Ore Reserve update on-track for September Quarter

• Initial phase of Resource diamond drilling completed at Kulumalia, comprising 19 holes for 3,820m, with results to be incorporated into the Misima Resource and Reserve update expected in the September quarter.

• Multiple new wide, mineralised intercepts outside of the Reserve pit shell

• Both high grade gold and silver assays returned, with highlights including:

• GDD108 3m @ 8.3g/t Au & 87.2g/t Ag from 1.5m, and

  • 21.3m @ 1.69g/t Au & 30.5g/t Ag from 218m

• GDD109 6m @ 2.32g/t Au & 46.5g/t Ag from 142m, and

  • 21.5m @ 0.94g/t Au & 121g/t Ag from 210.9m

• GDD110 19.4m @ 0.85g/t Au & 60.8g/t Ag from 94m, including

  • 3m @ 2.53g/t Au & 228g/t Ag from 104m

• Geological logging and mapping has improved understanding of the ore body, which will be incorporated into the new Resource model. New targets have been generated from the updated interpretation.

• Follow-up drilling is now underway at Kulumalia, ahead of a program of geotechnical drilling which will contribute to mining studies in the second half of 2021.

Kingston Resources Limited (ASX: KSN ) ( Kingston or the Company ) is pleased to report significant new results from the latest holes of the Resource drilling program at Kulumalia, located at the southern end of the main Umuna orebody at its flagship 3.6Moz Misima Gold Project in PNG.

These holes have returned multiple new wide, mineralised intercepts outside of the Reserve pit shell, increasing geological confidence in the existing Resource and Reserve models. Consistent with previously reported results (see ASX announcements 8[th] March 2021 and 10[th] May 2021), these results have also delineated new mineralisation beneath the current life-of-mine plan.

Kingston Resources Managing Director, Andrew Corbett, said: “The Kulumalia drill program has been a great success, returning intercepts of significant grade and width that have confirmed the mineralisation style across most of the Kulumalia area. This drilling has significantly advanced our understanding of the geology at Kulumalia, with expected positive implications for the life-of-mine plan in the southern portion of the proposed Umuna pit.”

“Following the latest program of Resource drilling at Kulumalia, the rigs completed a short drilling program at the Cooktown Stockpile aimed at increasing confidence in that component of the Resource. The rigs have now returned to Kulumalia for follow-up drilling.

“These programs put us on-track to deliver updated Resource and Reserve estimates in the September quarter, which will in turn feed into a Definitive Feasibility Study (DFS) for the Misima Gold Project. The DFS will be our core focus over the second half of this year, alongside the Environmental and Social Impact Assessment (ESIA) works which are ongoing. The team is also preparing for a geotechnical drilling program that will commence in July.

“Our ability to successfully deliver these work programs against the backdrop of continued global uncertainty generated by the COVID-19 pandemic is testament to the hard work and commitment of the Kingston team. We are now gearing up to move to the next stage of development for the Misima Project as we advance the mining studies and approvals.”

Silver Mineralisation

Drilling continues to confirm the presence of unexpectedly high-grade silver mineralisation that is spatially located within and peripheral to the gold-rich mineralised zone.

Best silver intercepts from the latest results include:

• GDD105 3.6m @ 46.9g/t Ag & 0.04g/t Au from 8.5m • GDD107 1.2m @ 48.5g/t Ag & 0.03g/t Au from 79m • GDD108 1.5m @ 34.8g/t Ag & 3.03g/t Au from 3m 1.5m @ 32.8g/t Ag & 5.67g/t Au from 212m 12m @ 44.0g/t Ag & 1.73g/t Au from 218m • GDD109 2m @ 52.2g/t Ag & 0.1g/t Au from 43m 2m @ 38.4g/t Ag & 0.28g/t Au from 70m 6m @ 46.5g/t Ag & 2.32g/t Au from 142m 27.7m @ 107g/t Ag & 0.84g/t Au from 210.9m • GDD110 1m @ 57.7g/t Ag & 0.42g/t Au from 94m 3m @ 228g/t Ag & 2.53g/t Au from 104m 2m @ 91.3g/t Ag & 1.19g/t Au from 110m 5m @ 29.7g/t Ag & 0.11g/t Au from 116m

High-grade silver intercepts are calculated independently of gold with a silver cut-off grade of 24g/t determined using commodity price assumptions, mining assumptions, operating costs and recoveries as published in the Misima PFS and Resource and Reserve Statement (see ASX Announcement 24 November 2020).

• 10.8m @ 3.4g/t Au & 2.6g/t Ag from 226.7m.

Updated Interpretation

Drilling from the Kulumalia Resource definition program has resulted in new insights into the nature of the geology and mineralisation at Kulumalia. Drilling confirms that gold-silver and silver mineralisation is hosted by all lithologies and is structurally controlled as breccias and quartz veins and stockworks. Continuity of the main mineralised structure at Kulumalia is confirmed, with occasional spatial discontinuities interpreted as being due to changes in dip-direction and offsets by late north/south trending structures. Characteristics of the mineralisation and alteration system are inferred to represent different depths of the original mineral system before displacement supporting extension potential along strike and up and down dip. The main mineralised structure at Kulumalia has been intersected at deeper levels progressively towards the east as shown in GDD108.

Improved structural understanding has highlighted the possibility of repeat extensions of the Kulumalia and Umuna structures to the north and east, with shallow mineralised structures in the hanging wall to the south. Future programs are designed to test the mineralisation potential adjacent to Kulumalia, and extensions along strike and down dip on splays and structures peripheral to the main Umuna deposit.

Next Steps

Drilling at Kulumalia will continue to infill the existing drill pattern and test shallow mineralisation potential within the Reserve and Production Target pit shells. Geotechnical drilling for the Feasibility Study is scheduled to commence in Q3, with various work programs for the Feasibility Study and ESIA ongoing.

•	Misima Island forms part of the Louisiade Archipelago which is	a continuation
	of the Papuan Fold Belt of the Papuan Peninsula offshore eastwards through
	the Papuan Plateau. The oldest rocks on Misima are Cretaceous to Paleogene
	metamorphic rocks, which can be subdivided into the western Awaibi
	Association and the younger overthrust eastern Sisa Association that is host to
	the gold and copper mineralization. The two associations are separated by an
	original thrust fault with later extensional activation.
•	Mineralisation deposit style on Misima Island is best described as		Low
	Sulphidation Epithermal due to the veining and characteristics, the dominance
	of Ag Zn Pb Au Cu Mn geochemistry as well as complex alteration styles and
	geometry, and strong association with precursor porphyry Cu Au style alteration.
•	Styles of mineralisation observed across Misima Island include multiphase
	hydrothermal breccia, stockworks both sheeted and three-dimensional, skarn,
	jasperoidal replacement, and poorly banded vein infill of quartz	and carbonate
	with associated pyrite, galena, sphalerite, barite and minor tetrahedrite.
	Combining all data sets with orientated drill core data for
	mineralised veins and breccias defines the predominant structure
	trends in the deposit and will provide the foundation for the
	resource model. The Current interpretation is that Kulumalia
	mineralisation is open along strike and at depth, with the potential
	for hangingwall splays and mineralised structures.
