Misima Resource increases to 3.21Moz of gold, 18.2Moz of silver

Higher-confidence Indicated Resource of 49.9Mt @ 0.95g/t for 1.52Moz to underpin Pre-Feasibility Study

• JORC 2012 Mineral Resource update for the Misima Gold Project delivers a 15% increase in contained gold ounces and 30% increase in contained silver ounces to:

• 105Mt @ 0.93g/t for 3.21Moz (Indicated and Inferred).

• 17% increase in total Indicated ounces, available for conversion to Ore Reserves, to:

• 49.9Mt @ 0.95g/t for 1.52Moz.

• Pre-Feasibility Study, including Ore Reserve estimate, to commence immediately with targeted completion by year-end.

• Ewatinona confirmed as starter pit delivering initial feed for the Pre-Feasibility Study.

• Substantial potential to further expand the Mineral Resource and upgrade additional Inferred ounces.

• Resource drilling to re-commence at Ewatinona once travel suspensions are lifted.

Kingston Resources Ltd (ASX: KSN) is pleased to report a significant increase in the JORC 2012 Mineral Resource Estimate for its flagship Misima Gold Project, PNG , incorporating the results of recent successful drilling programs and updated gold price assumptions.

The updated Misima Resource has delivered a 15% increase in total gold ounces and 30% increase in total silver ounces and now comprises an Indicated and Inferred Mineral Resource of 105.5Mt @ 0.93g/t Au and 5.4 g/t Ag for 3.2Moz Au and 18.2Moz Ag , (see Table 1), confirming the Project’s status as one of the most significant mid-tier gold development opportunities in the Asia-Pacific region.

Kingston commenced drilling at Misima in June 2018 with 49% equity ownership in the project, the Company has since increased its equity ownership to 80.5% and has a non-binding agreement to move to 100% ownership. Early work highlighted that a starter pit would considerably enhance project economics. With this in mind, the exploration strategy has focused on near-surface opportunities, and the Company can now confirm Ewatinona as the intended starter pit for Misima.

The Misima Resource update has focused on updating the geological model at Ewatinona while also revising project assumptions around cut-off grade and gold price inputs. The updated Resource will now underpin the Pre-Feasibility Study (PFS), which is expected to be complete by the end of 2020. The PFS will be enhanced by the 17% increase in Indicated ounces to 1.52Moz, of which 97% sits within a US$1,400 pit shell. The

Umuna Deposit currently contains 94% of the total Resource ounces and is expected to underpin the PreFeasibility work focusing on a large-scale, long-life open pit mining project.

Kingston Resources Managing Director, Andrew Corbett, said: “This is a great result for Kingston shareholders, with the substantial increase in gold and silver ounces firmly establishing Misima as one of the most exciting new mid-tier gold development opportunities in the Asia-Pacific. The significant increase in overall ounces, and in particular the 17% increase in Indicated ounces to 1.52Moz, provides a fantastic platform from which to launch our mining studies. Our improved understanding of Ewatinona is also a key step forward for the project and clearly establishes our proposed starter-pit.

“A special thanks goes out to the Kingston geological team, headed up by our Chief Geologist Stuart Hayward, for advancing the Project to this point. Under Stuart, the team has significantly advanced its understanding of Umuna and Ewatinona, and we are all looking forward to making the transition to mining studies to demonstrate the strength of the Misima Gold Project.

“Looking ahead, there are considerable operational and economic benefits to be unlocked by focusing on Ewatinona and Umuna. Both areas leverage off previous mining access which remains in place, they have both been mined historically, and had a combined total of over 90 million tonnes of ore processed through a standard CIL plant. Kingston therefore has considerable historical information on the mining, milling and geotechnical characteristics of these orebodies, as well as the historical processing plant design. Alongside giving us confidence in the Project’s future, this information will save time and costs in delivering the upcoming PFS.

“On the ground, as soon as we can re-commence exploration activity, drilling will focus on completing the infill program at Ewatinona cut short by domestic and international travel restrictions. Following that, the Resource work completed by the team has highlighted a number of priority areas where drilling could upgrade further near-surface Inferred ounces. We look forward to recommencing drilling in the near term and continuing to work with the people of Misima and PNG on the world-class Misima Gold Project.”

Exploration to drive further Resource upgrades

Kingston’s primary focus for ongoing drilling in 2020 will be on upgrading and potentially extending both the Umuna and Ewatinona Resource with a focus on near-surface opportunities.

Key growth opportunities at Umuna include: (see Figures 1, 4 & 5):

• Follow-up drilling and Resource model update at Umuna and Umuna East, building on all drilling completed to date;

• Extensional and in-fill drilling of the southern extensions of Umuna at Kulumalia; and

• Additional Umuna extensions including Tonowak and Padocol.

The Cooktown Stockpile exploration target material (3.6Mt @ 0.5g/t to 0.7g/t Au for 58,000 to 81,000oz) reported on 21st March 2019, is not included in any tonnes and grade calculations in the 2020 mineral resource estimation for Umuna.

Growth opportunities at Ewatinona include: (see Figures 2 and 6)

• Resource drilling to both upgrade and extend the Ewatinona Resource;

• Follow up extensional targets outside the current Resource identified from recent field work;

• Follow up drilling on the Abi discovery 600m SE of Ewatinona; and

• Resource model update to include additional nine holes for which assays were received post Resource cut-off date.

The new Misima Resource of 105.5Mt @ 0.93g/t Au for 3.21Moz Au builds on successful historical Placer production at Misima of 3.7Moz Au before mining ceased in 2001 in a sub-US$300/oz gold price environment.

Over its mining history, the operation was recognised as having one of the world’s lowest cost conventional gold extraction plants[1] . Kingston expects to benefit from many of the factors which contributed to this low-cost milling – in particular, the deposit’s very favourable metallurgical characteristics of soft ore and coarse grind size.

With a production history of 3.7Moz and a current Resource of 3.2Moz, Misima now has a total known gold endowment of over 7Moz. This positions Misima as a world-class gold deposit in a region known to host giant gold and copper-gold occurrences.

The Umuna Resource update has increased the Umuna Resource tonnes by 29% and overall ounces by 7% to 97.9Mt @ 0.94g/t for 3.01Moz AU and 18.2Moz of Ag. A significant proportion of the current Indicated Resource ounces reports within moderately priced pit shells, as shown in Table 2 below.

Having a high component of Indicated ounces inside relatively conservatively priced pit shells is encouraging as the Company makes the transition to mining studies and targets the completion of an Ore Reserve by the end of this year.

Technical Note Misima Gold Project Milne Bay Province, Papua New Guinea

Compiled by Competent Person: Stuart Hayward BAppSci (Geology), MAIG

Introduction

This technical note on the Misima Gold Project (the Property), has been prepared by Stuart Hayward for Kingston Resources Limited (KSN or the Company).The Misima Gold Project is located within EL1747 that encompasses the eastern half of Misima Island, Milne Bay Province, Papua New Guinea (PNG). Misima is located approximately 625km east of Port Moresby, the capital of PNG.

This technical note has been prepared to form part of the technical documentation for an ASX public release and is accompanied by a JORC 2012 Table 1 in accordance with the JORC Code 2012. The technical note summarises the Misima Gold Project mineral resource in terms of the JORC 2012 guidelines and in respect to reporting that part of the resource that has “reasonable prospects for eventual economic extraction”.

Further specific details are noted in the attached Umuna deposit JORC 2012 Table 1 and Ewatinona deposit JORC 2012 Table 1, and by referencing previous Kingston public reports.

Project Geology and Mineralisation

The Misima Gold Project comprises two main deposits, Umuna and Ewatinona, and multiple reconnaissance exploration targets along and adjacent to the 10km strike length of the Umuna Fault Corridor that hosts the historical Umuna deposit, and Quartz Mountain area that hosts the Ewatinona deposit (Figure 7).

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 mineralisation. 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 carbonate base-metal epithermal due to the vein 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. Mineralisation is strongly structurally controlled by pre-existing structures that have been reactivated and mineralised over time.

The Umuna deposit is a complex fault array with a large fault zone hosting the majority of the precious metal mineralisation, with numerous ancillary splays developed in the footwall to the main structure. Internal structures within the fault complex and the intersection of structures and splays with the dominant Umuna Fault, are loci for zones of well-developed mineralisation. A series of north west trending splays intersect and control the loci of the higher-grade material within the Umuna fault zone. Surrounding the Umuna lode, and most widely developed on the eastern (footwall) side, is a broad peripheral zone of lower grade mineralisation in quartz veins, often occupying shears, and of linear and irregularly shaped volumes of strongly jointed to brecciated rocks. The schists tend to carry shear or breccia mineralisation with a higher frequency of strong

==> picture [131 x 37] intentionally omitted <==

jointing and brecciation in the more compact intrusives and Ara Greenschist. Intrusive contacts are commonly brecciated and mineralised which, with their frequent shallow dips, has the effect of spreading mineralisation laterally in contrast to the steep attitude of Umuna lode mineralisation. As noted, mineralisation is dominantly structurally controlled, however, strong secondary stratigraphic controls are also observed, in particular, where skarn style mineralisation is developed at the Halibu Limestone – Ara Schist contacts.

The Ewatinona deposit is dominated by brecciated porphyry units which are cut by faults trending in three major directions (northwest, west northwest and southwest) with steep north and north east dips. Mineralised structures can range from crackle brecciated porphyry with base metal sulphide and quartz-carbonate-base metal sulphide infill, to more well-defined fault breccia with stockwork veining and crackle brecciation haloes. Orientation of mineralised structures in mined out areas is interpreted from 3D implicit modelling of grade distribution in grade control data and supported by pit mapping. Combining all data sets with orientated drill core data for mineralised veins and breccias defines the predominant structural trends in the deposit and the foundation for the resource model. The current interpretation is that Ewatinona mineralisation is open along strike and at depth.

Drilling

Diamond and RC drilling was completed on Misima from 1978 until Placer ceased mining operations in 2000. WCB Resources completed five diamond drill holes in 2017 focussed on porphyry copper targets adjacent to the Umuna pit. Kingston has completed 85 diamond drill holes across EL1747 since 2018. Twenty-seven new drill holes completed in 2019 and 2020 are included in the Ewatinona geology model and mineral resource update. The Umuna geology and resource model is not informed by new data and remains unchanged from 2017.

All historic diamond drill holes are PQ3, HQ3, or NQ3 in core size. Historic RC drilling comprise 4”to 5” diameter hammers. Kingston drill holes are all PQ3 and HQ3 with every core run orientated using electronic downhole tools.

Drill hole data is managed in an acQuire relational database with check and validation procedures assessing the stored data as being of a quality suitable for mineral resource estimation.

Sample Preparation and Analysis

From 1989-2000 sample preparation was completed on site with whole core prepared and assayed due to problems associated with splitting the drill core. RC samples were riffle split. Gold was determined using a screen fire assay and silver, copper, lead and zinc using an AAS at the Placer on site lab. Where gold was > 0.5 Au ppm, a check assay was carried out at Classic Labs in Townsville using screen fire assay.

Kingston diamond drill core is sampled in 2m intervals away from the ore zone or to lithological contacts, whichever is shorter. In mineralised areas, core is sampled in 1 to 2m lengths or to lithological contacts. Minimum interval sampled being 0.5m. All core was cut in half lengthwise using a diamond saw parallel to the orientation line. PQ core up to hole GDD051 were assayed using quarter core to reduce sample weight. All subsequent drill holes are assayed using half core. Half core samples were sent for assay and the other half retained as reference core in the core tray on site. Samples are transported to Intertek in Lae where they are dried and crushed to 95% passing 3mm. The crushed sample is then pulverised and a 50g charge is taken for gold analysis by fire assay in Lae. A 100g pulp from each sample is flown to Townsville where it is analysed using Intertek’s Four Acid 33 Element package. An optical emission spectroscopy (OES) finish is provided for Ag, Pb, Zn and Cu values that report over-range assays.

==> picture [131 x 37] intentionally omitted <==

Quality assurance (QA) and quality control (QC) protocols included the monitoring and analysis of inserted certified reference material, blanks and duplicate samples to monitor assay sample data for contamination, accuracy and precision and to ensure sample representivity. Check analysis of selected samples by an alternative laboratory (ALS Perth) in Australia has been completed to monitor laboratory performance.

Overall, the precision and accuracy of the total dataset for Umuna and Ewatinona is of acceptable standard and assessed as suitable for mineral resource estimation for the gold mineralisation and deposit style.

Survey Control

All Kingston diamond drill holes are surveyed using high accuracy RTK GPS equipment operated by registered surveyors. All spatial data sets are located relative to a high accuracy LiDAR topography survey completed in 2018. Historical spatial data sets have been translated from local grid systems to GDA94 Zone 56 based on translation derived from the detailed survey and cross-referenced with LiDAR topography.

Mineral Resource Estimation

The mineral resource model for Umuna has not been modified in any way and can be referenced in the Kingston Resources ASX announcement released 27 November 2017, and in the 2017 resource report (McManus, 2017b).

The Ewatinona geology and mineralisation model has been revised and rebuilt using all available historical and new data sets. The data sets have been compiled and cross referenced with each other to build a threedimensional model of the Ewatinona mineralised structures that are used as inputs to the resource model. Orientated drill core has provided corroborating data supporting interpretation of 3D structure trends.

Grade estimation has been completed by an independent consultant resource geologist Mr. Chris De-Vitry (MAIG, AUSIMM) of Manna Hill Geoconsulting. Mr De-Vitry has reviewed this report and consents to the inclusion of his work in the form and context in which it appears. Geology, structure, and validated data inputs to the resource estimation are managed and provided by Kingston with geological and mineral system context provided through direct consultation between Mr. De-Vitry and Mr. Hayward (CP).

The gold and silver block grade were estimated using Ordinary Kriging with Isatis software. Pb, Zn and Cu estimates were determined by inverse distance squared interpolation.

Ordinary Kriging is an appropriate method to use if top cutting or outlier restriction is carried out and the data is domained.

Specific details of modelling parameters and modelling approach can be referenced in the attached JORC 2012 Table 1.

Mineral Resources

Individual Mineral Resources were calculated for Umuna and Ewatinona, with results combined to calculate a total resource for Misima. Considerations, assumptions, and modifying factors specific to each deposit and common across the project are discussed in detail in the next section.

The Misima Mineral Resource totals 105.5Mt @ 0.93g/t Au and 5.4g/t Ag, for 3.21Moz gold and 18.2Moz silver (Table 3), comprising 47% classified as Indicated containing 1.52Moz gold, an increase of 7% in gold ounces and 29% in tonnes.

==> picture [131 x 37] intentionally omitted <==

Geology models for both deposits have been evaluated using Whittle pit shells at gold price points of USD$1400, USD$1500, USD$1600, USD$1700 and USD$1800, and USD$20 for silver. Pit shells were generated based on input mining parameters that are unchanged from previous resource estimations and are based on historical operational design factors and performance. Cut-off grades at each deposit have been assessed by Kingston as meeting the test of having reasonable prospects of eventual economic extraction.

Umuna mineral resources are estimated as 97.9Mt @ 0.94g/t Au and 5.6g/t Ag, for 3.01Moz gold and 17.5 Moz silver (Table 3). The Umuna resource update is based on an unchanged existing geology/block model that has been re-evaluated based on revised gold and silver price assumptions as input to development of Whittle pit shells for reporting. Resource classification has not been changed or modified from previous resource estimations, and mineral resources at Umuna are reported as material classified as indicated and inferred ≥ 0.4g/t Au cut-off within a USD$1700 pit shell, and material at ≥0.8 g/t Au cut-off immediately down dip and along strike that does not extend significant distances (50-75m) from the pit shell. The increase in contained gold and silver is due to the combined effect of cut-off grade and increased volume of material reporting within the USD$1700 pit shell.

It must be noted that the Cooktown Stockpile exploration target material (3.6Mt @ 0.5g/t to 0.7g/t Au for 58,000 to 81,000oz) reported on 21st March 2019, is not included in any tonnes and grade calculations in the 2020 mineral resource estimation for Umuna and has been considered as waste in pit optimization calculations.

Ewatinona mineral resources are estimated as 7.5Mt @ 0.83g/t Au and 3.0g/t Ag, for 0.2Moz Au and 0.7Moz Ag (Table 3). The Ewatinona mineral resource has been significantly updated and improved using all available historical and recently acquired geological data to develop a well-supported three-dimensional geological, structural and mineralisation model. Mineral resources at Ewatinona are reported as material classified as Indicated and Inferred ≥ 0.4g/t Au cut-off within a USD$1700 pit shell. Classification at Ewatinona has been revised to include 25% of the resource now assessed as Indicated using the approach detailed in the next section.

Both resource models are assessed as fit for purpose as inputs into mining studies planned for 2020.

Consideration of Input Parameters and Assumptions

The Misima Gold Project 2020 Mineral Resource Estimate and reporting has been completed with reference to the following summary of key considerations and assumptions. Kingston consider that the reported resources for both Umuna and Ewatinona have reasonable potential for eventual economic extraction.

General Considerations

Environmental, social, and geographical constraints:

• The area immediately around the mine lease has been subject to historical mining and is all secondary regrowth jungle and forest.

• Socially, the local people are accepting of mining, and after the closure of the Placer mine, many of the local people now work on fly-in-fly-out rosters to other mines. The local community brings a significant level of mining and trades talent and expertise to any future project as well as support for re-opening the mine.

• Kingston have continued a program of regular water quality and sediment sampling at key sample locations around the project and active exploration areas. A majority of sample locations are the same as those established by Placer/Placer and show no degradation in water quality or sediment loads due to exploration activities.

• Topographically, ore can be accessed early during project development with minimal stripping from some parts of both the Umuna and Ewatinona deposits.

• Topography is derived from a high accuracy LiDAR survey completed in 2018 and is used as a ground truth reference point for assessing historical spatial data sets.

Umuna

Geology and Block Model:

• No changes or modifications have been made to the underpinning geology and resource/block model from the 2017 resource update.

• All variables within the block model are retained and are unchanged.

• Gold and silver grades have not been re-estimated or modified in any way.

• Spatial data has been retained with reference to the historic local mine grid.

Mining Method:

• Mining is assumed to be by Open Pit.

• Geotechnical, pit wall stabilities and slope assumptions and parameters are well known from previous mining.

• Selective mining unit and grade control assumptions and parameters have all been based on previous mining.

• Material outside of the USD$1700 pit shell and reported at a higher cut-off grade (0.8g/t Au) is included in the resource as it is assessed as having reasonable potential for eventual economic extraction through specific design and mining schedule modifications developed during the life of mine, e.g. steeper pit walls and accelerated schedule.

Metallurgical Factors:

• There is a significant history of mining of the project with supporting mill records. The recovery, tails and milling factors and assumptions are well known and utilised in development of Whittle pit shells (recoveries: 92% for gold and 50% for silver).

==> picture [131 x 37] intentionally omitted <==

Cut-Off Grade:

• Shannon and Stoker (2013 Nat-Inst 43-101 report) used cut off grades determined from an optimized Whittle pit at a $US1,200 gold value.

• The same cut off grades were again used in 2015 (Shannon & Stoker 2015), and 2017 (McManus 2017a). A cut-off grade analysis undertaken during the two later reports showed that a lower cutoff could be achievable with Skandus considering that the 0.5g/t cut-off as being appropriate when reporting the 2017 resource in accordance with JORC (2012) (McManus, 2017b).

• Kingston has revised the gold cut-off grade and consider a 0.4g/t Au cut-off as being reasonable and appropriate for reporting in-pit resources when considering historical mine performance and higher gold price assumptions based on forward looking gold price forecasts.

• A cut-off grade of 0.8g/t Au is used to report material below and outside of the USD$1700 pit shell that could be reasonably potentially economically extracted through modified mining and mine design approaches at the time. Only blocks within a reasonable distance (50-75m) from the bottom of the USD$1700 pit-shell have been included in the resource.

Continuity and Classification:

• Classification has not changed between the Skandus 2017b (JORC 2012) resource and the Kingston 2020 update.

• During classification of the Skandus 2017b (JORC 2012) resource, care was taken to ensure that contiguous blocks were classified in section and that a computer generated ‘above a value’ classification was not the main driver to avoid the ‘spotted dog’ complex. (Stephenson, 2006). This also ensures that small pods of distant ore are not included in the reported resource that may not be economically extracted.

Exploration Considerations:

• Placer undertook minimal exploration outside of the designed pit shell. Mineralised structures continuing at depth were not drilled with sufficient density beyond the pit shell to be included in a resource at the time.

• The 310 striking mineralization as seen in the Tonowak and Kulumalia structures, often formed in shoots within the structure. The mineralisation is not well defined by drilling due to drill orientation, and the main Umuna structure and contact being the focus of most drilling. Ore at the intersection of structures within the main Umuna Structure corridor may account for much of the positive reconciliation in both tonnes and grade that was experienced during the life of the mine.

• Potential exists for defining near surface oxide mineralisation along parallel structures and splays adjacent to the historic mining footprint.

• Drilling density and thus block estimation has limited the bottom of the various Whittle pit optimisations.

• Mineralised material stockpiled by Placer on the crest of the historical pit (Cooktown Dump Stockpile) has not been included in the mineral resource estimate and does not contribute in any way to tonnes and grade and contained ounces calculations. Resource estimation of this material would allow inclusion in mine planning, potentially improving project economics.

Ewatinona

The Ewatinona deposit has undergone a significant revision of the geology and mineralisation model based on the addition of 27 diamond drill holes for 4608.80m completed by Kingston between April 2019 and February 2020. A combination of high quality drilling data including orientated structures, surface mapping and sampling, compilation and review of historical exploration, and production data sets, has resulted in a

==> picture [131 x 37] intentionally omitted <==

significantly improved understanding of the geology and controls on mineralisation, and thus confidence in 3D spatial interpretation and modelling.

Geology and Block Model:

• All available historical and new data sets were compiled and cross referenced with each other to build 3D mineralised structures that were used as inputs to the revised Ewatinona geology and mineralisation model. Orientated drill core has provided corroborating data supporting interpretation of 3D structure trends.

• Exploratory data analysis of data sets and geochemistry links gold grade and presence of mineralisation and mineralised structures in drill core.

Topography and Survey Datum:

• Spatial data sets have been developed and utilised with reference to the GDA94 Zone 56 datum. GDA94 has been assessed as being effectively the same as PNG94.

• The use of GDA94 Zone 56 (PNG94) represents a change from the Skandus 2017b (JORC 2012) model that was completed in a truncated AMG grid system. Kingston have completed a rigorous high accuracy ground survey and determined a spatial data translation for historical data sets to GDA94 datum.

• Topography is derived from a high accuracy LiDAR survey completed in 2018 and is used as a ground truth reference point for assessing historical spatial data sets.

• The Kingston 2020 (JORC 2012) resource is built and generated in GDA94 Zone 56 datum.

Mining Method:

• Mining is assumed to be by Open Pit.

• Geotechnical, pit wall stabilities and slope assumptions and parameters are well known from previous mining.

• Selective mining unit and grade control assumptions and parameters have all been based on previous mining.

• Material outside of the USD$1700 pit shell has not been reported within the Ewatinona 2020 resource.

Metallurgical Factors:

• Metallurgical factors used in assessing Ewatinona are the same as those used for Umuna. Recoveries used are 92% for gold and 50% for silver based on historical project performance.

Continuity and Classification:

• Classification has been revised in the 2020 Ewatinona model to reflect a combination of confidence in the underpinning geology model and 3D spatial models of mineralisation/structures, supported and corroborated by drilling spacing, and estimation metrics such as slope of regression for Au and Ag, Kriging variance, and distance to nearest samples informing a block estimate.

• 25% of material in the USD$1700 pit shell immediately below the center of the historical open pit and within the volume tested by new drilling completed by Kingston, is classified as Indicated.

• The remainder of material is classified as Inferred.

• This represents a material change from the Skandus 2017b (JORC 2012) resource.

Grade Estimation and Resource Reporting:

• A grade shell was deemed necessary to reducing the smearing/mixing of weakly mineralised and mineralised material during kriging of Au. Implicit models of gold from drill holes were created utilising the interpreted structural controls to guide the construction of a radial basis function (RBF) in

==> picture [131 x 37] intentionally omitted <==

Leapfrog. The resultant 0.2g/t Au shell is considered to appropriately reflect the geometry and spatial distribution of mineralised structures based on the available drill hole data. The choice of a 0.2g/t Au grade boundary is well below the resource cut-off of 0.4 g/t Au which will reduce conditional bias.

Cut-Off Grade:

• The last reported mineral resources were reported at 0.5 g/t cut-off based on assessment of previous reviews by Shannon & Stoker 2013, Shannon & Stoker 2015, and 2017 (McManus 2017b).

• Kingston has revised the gold cut-off grade and considers a 0.4g/t Au cut-off as being reasonable and appropriate for reporting in-pit resources when considering historical mine performance and higher gold price assumptions based on forward looking gold price forecasts.

About Kingston Resources

Kingston Resources is a metals exploration company which is focused on exploring and developing the worldclass Misima Gold Project in PNG. Misima hosts a JORC resource of 3.2Moz Au. Misima was operated as a profitable open pit mine by Placer Pacific between 1989 and 2001, producing over 3.7Moz before it was closed when the gold price was below US$300/oz. The Misima Project offers outstanding potential for additional resource growth through exploration success targeting extensions and additions to the current 3.2Moz Resource base. Kingston currently owns 80% of the Misima Gold Project.

In addition, Kingston owns 75% of the high-grade Livingstone Gold Project in Western Australia where active exploration programs are also in progress.

								WCB, and observations, data analysis and interpretation from
								recent diamond drilling.
								The Ewatinona deposit is dominated by brecciated porphyry
								units which are cut by faults trending in three major directions
								(northwest, west northwest and southwest) with steep north
								and north east dips. Mineralised structures can range from
								crackle brecciated porphyry with base metal sulphide and
								quartz-carbonate-base metal sulphide infill, to more well-
								defined fault breccia with stockwork veining and crackle
								brecciation haloes. Lithology does not appear to influence
								mineralisation and grade distribution within recent drilling and
								has not been used as a domain in resource estimation.
								Isotropic, unbiased, 3D implicit modelling of grade control data
								points maps out dominant structure trends of mineralisation in
								the open pit mined by Placer. Interpretation of planar surfaces
								from grade shells at 0.2, 0.3, 0.4, 1.0 and 2.5g/t Au, define a
								set of structures that are coincident with and supported by pit
								mapping by Placer, and Kingston. Highest grade shells are
								located at the intersection of interpreted structures. There is a
								general alignment with the steep north to northeast dipping
								structure trends determined from orientated drill core.
								Combining all data sets with orientated drill core data for
